Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for network energy savings using a cell wake-up signal (C-WUS) and/or a simplified version of a synchronization signal block (SSB).
Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, or the like). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).
A wireless network may include one or more network nodes that support communication for wireless communication devices, such as a user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communications and uplink communications. “Downlink” (or “DL”) refers to a communication link from the network node to the UE, and “uplink” (or “UL”) refers to a communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via a local link (e.g., a sidelink (SL), a wireless local area network (WLAN) link, and/or a wireless personal area network (WPAN) link, among other examples).
The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate on a municipal, national, regional, and/or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink, using CP-OFDM and/or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful.

The foregoing has outlined rather broadly the features and technical advantages of examples according to the disclosure in order that the detailed description that follows may be better understood. Additional features and advantages will be described hereinafter. The conception and specific examples disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present disclosure. Such equivalent constructions do not depart from the scope of the appended claims. Characteristics of the concepts disclosed herein, both their organization and method of operation, together with associated advantages, will be better understood from the following description when considered in connection with the accompanying figures. Each of the figures is provided for the purposes of illustration and description, and not as a definition of the limits of the claims.
While aspects are described in the present disclosure by illustration to some examples, those skilled in the art will understand that such aspects may be implemented in many different arrangements and scenarios. Techniques described herein may be implemented using different platform types, devices, systems, shapes, sizes, and/or packaging arrangements. For example, some aspects may be implemented via integrated chip embodiments or other non-module-component based devices (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail/purchasing devices, medical devices, and/or artificial intelligence devices). Aspects may be implemented in chip-level components, modular components, non-modular components, non-chip-level components, device-level components, and/or system-level components. Devices incorporating described aspects and features may include additional components and features for implementation and practice of claimed and described aspects. For example, transmission and reception of wireless signals May include one or more components for analog and digital purposes (e.g., hardware components including antennas, radio frequency (RF) chains, power amplifiers, modulators, buffers, processors, interleavers, adders, and/or summers). It is intended that aspects described herein may be practiced in a wide variety of devices, components, systems, distributed arrangements, and/or end-user devices of varying size, shape, and constitution.
So that the above-recited features of the present disclosure can be understood in detail, a more particular description, briefly summarized above, may be had by reference to aspects, some of which are illustrated in the appended drawings. It is to be noted, however, that the appended drawings illustrate only certain typical aspects of this disclosure and are therefore not to be considered limiting of its scope, for the description may admit to other equally effective aspects. The same reference numbers in different drawings may identify the same or similar elements.
For various reasons, network energy saving and/or network energy efficiency measures are expected to have increased importance in wireless network operations. For example, although New Radio (NR) generally offers a significant energy efficiency improvement per gigabyte over previous generations (for example, LTE), new NR use cases and/or the adoption of millimeter wave frequencies may require further improvements to energy efficiency. Furthermore, even with the improved energy efficiency of NR, energy costs still account for a significant proportion of the cost to operate a wireless network. For example, according to some estimates, energy costs are about one-fourth the total cost to operate a wireless network. The largest proportion of energy consumption and/or energy costs are associated with a radio access network (RAN), with data centers and fiber transport accounting for smaller shares. Accordingly, measures to increase network energy savings and/or improve network energy efficiency are important factors that may drive adoption and/or expansion of wireless networks.
Various aspects relate generally to a cell wake-up signal (C-WUS) associated with a cell discontinuous reception (DRX) mode. Some aspects more specifically relate to contents and formats of a C-WUS to be transmitted by a user equipment (UE) to activate a network node from an inactive or sleep state. In some aspects, a network node may transmit, and a UE may receive, C-WUS configuration information indicating multiple C-WUS formats, with each C-WUS format, of the multiple C-WUS formats, being associated with respective information to be included in the C-WUS transmission.
The UE may transmit, and the network node may receive, a C-WUS associated with a C-WUS format of the multiple C-WUS formats. The C-WUS may include the respective information associated with the C-WUS format. In some examples, the network node may switch from a first network energy state (NES) to a second NES in connection with receiving the C-WUS. For example, the network node may switch from a sleep state or an inactive state to an active state in connection with receiving the C-WUS. In some examples, the UE and the network node may communicate based in part on the respective information included in the C-WUS and associated with the C-WUS format of the C-WUS. For example, the information included in the C-WUS may include information relating to traffic to be transmitted by the UE, an energy state of the UE, a requested time for the UE to receive a system information block type 1 (SIB1), a sidelink scheduling request, beam information, configuration preferences, and/or capability information, among other examples.
Various aspects relate generally to a simplified version of a synchronization signal block (SSB) for network energy savings. Some aspects more specifically relate to contents of the simplified version of the SSB including information about NESS and/or support of a wake-up radio (WUR) of a UE. In some aspects, a network node may transmit, and a UE may receive, a first SSB associated with an NES of the network node. The first SSB may include a first master information block (MIB) indicating first information that is different from second information indicated in a second MIB of a second SSB associated with a second NES of the network node. The UE and the network node may communicate based at least in part on the first information included in the first SSB. In some examples, the first NES may be associated with a reduced power consumption by the network node, as compared to the second NES, and the first information indicated in the first MIB of the first SSB may include a reduced amount of information, as compared to the second information indicated in the second MIB of the second SSB. In some examples, the first information may include information relating to one or more NESs of the network node and/or information indicating support for low power wake-up signal (LP-WUS) transmission associated with one or more WURs.
Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some examples, by including, in a C-WUS transmission, information in addition to an indication for the network node to switch to an active mode, the described techniques can be used to decrease signaling overhead between the UE and the network node once the network node receives the C-WUS and switches to an active state. Furthermore, by including information in the C-WUS transmission, instead of communicating the information between the UE and the network node after the network node receives the C-WUS and switches to the active state, the described techniques can be used to decrease latency of traffic (e.g., uplink traffic and/or sidelink traffic) to be transmitted by the UE and/or decrease an amount of time that the network node remains in the active state, thus increasing network energy savings. In some examples, by configuring different C-WUS formats associated with different information to be included in the C-WUS transmission, different C-WUS formats may be used to communicate different sets of information during C-WUS transmission, which may increase flexibility of the information included in C-WUS transmissions, resulting in further decreases in signaling overhead and latency and/or further increases in network energy savings.
In some examples, by transmitting first SSB associated with a first NES that is a different or simplified version of a second SSB associated with a second NES, the described techniques may be used to increase network energy savings in the first NES. In some examples, by including, in the first SSB, information relating to one or more NESs and/or support for LP-WUS transmission associated with one or more WURs, the described techniques may be used to decrease signaling overhead, increase network energy savings associated with the one or more NESs, and/or enable decreased power consumption by a UE using a WUR.
Various aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. One skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using other structure, functionality, or structure and functionality in addition to or other than the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.
Several aspects of telecommunication systems will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, or the like (collectively referred to as “elements”). These elements may be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.
While aspects may be described herein using terminology commonly associated with a 5G or NR radio access technology (RAT), aspects of the present disclosure can be applied to other RATs, such as a 3G RAT, a 4G RAT, and/or a RAT subsequent to 5G (e.g., 6G).
In some examples, a network node 110 is or includes a network node that communicates with UEs 120 via a radio access link, such as an RU. In some examples, a network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, a network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or a core network via a backhaul link, such as a CU. In some examples, a network node 110 (such as an aggregated network node 110 or a disaggregated network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and/or one or more DUs. A network node 110 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmission reception point (TRP), a DU, an RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, the network nodes 110 may be interconnected to one another or to one or more other network nodes 110 in the wireless network 100 through various types of fronthaul, midhaul, and/or backhaul interfaces, such as a direct physical connection, an air interface, or a virtual network, using any suitable transport network.
In some examples, a network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term “cell” can refer to a coverage area of a network node 110 and/or a network node subsystem serving this coverage area, depending on the context in which the term is used. A network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and/or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs 120 with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs 120 having association with the femto cell (e.g., UEs 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. A network node 110 for a femto cell may be referred to as a femto network node or an in-home network node. In the example shown in
In some aspects, the terms “base station” or “network node” may refer to an aggregated base station, a disaggregated base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, “base station” or “network node” may refer to a CU, a DU, an RU, a Near-Real Time (Near-RT) RAN Intelligent Controller (RIC), or a Non-Real Time (Non-RT) RIC, or a combination thereof. In some aspects, the terms “base station” or “network node” may refer to one device configured to perform one or more functions, such as those described herein in connection with the network node 110. In some aspects, the terms “base station” or “network node” may refer to a plurality of devices configured to perform the one or more functions. For example, in some distributed systems, each of a quantity of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to duplicate performance of at least a portion of the function, and the terms “base station” or “network node” may refer to any one or more of those different devices. In some aspects, the terms “base station” or “network node” may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the terms “base station” or “network node” may refer to one of the base station functions and not another. In this way, a single device may include more than one base station.
The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive a transmission of data from an upstream node (e.g., a network node 110 or a UE 120) and send a transmission of the data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that can relay transmissions for other UEs 120. In the example shown in
The wireless network 100 may be a heterogeneous network that includes network nodes 110 of different types, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, or the like. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and/or different impacts on interference in the wireless network 100. For example, macro network nodes may have a high transmit power level (e.g., 5 to 40 watts) whereas pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 to 2 watts).
A network controller 130 may couple to or communicate with a set of network nodes 110 and may provide coordination and control for these network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may communicate with one another directly or indirectly via a wireless or wireline backhaul communication link. In some aspects, the network controller 130 may be a CU or a core network device, or may include a CU or a core network device.
The UEs 120 may be dispersed throughout the wireless network 100, and each UE 120 may be stationary or mobile. A UE 120 may include, for example, an access terminal, a terminal, a mobile station, and/or a subscriber unit. A UE 120 may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and/or a satellite radio), a vehicular component or sensor, a smart meter/sensor, industrial manufacturing equipment, a global positioning system device, a UE function of a network node, and/or any other suitable device that is configured to communicate via a wireless or wired medium.
Some UEs 120 may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. An MTC UE and/or an eMTC UE may include, for example, a robot, an unmanned aerial vehicle, a remote device, a sensor, a meter, a monitor, and/or a location tag, that may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet-of-Things (IoT) devices, and/or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered a Customer Premises Equipment. A UE 120 may be included inside a housing that houses components of the UE 120, such as processor components and/or memory components. In some examples, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and/or electrically coupled.
In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a particular RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology, an air interface, or the like. A frequency may be referred to as a carrier, a frequency channel, or the like. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.
In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120c) may communicate directly using one or more sidelink channels (e.g., without using a network node 110 as an intermediary to communicate with one another). For example, the UEs 120 may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, or a vehicle-to-pedestrian (V2P) protocol), and/or a mesh network. In such examples, a UE 120 may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the network node 110.
Devices of the wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, channels, or the like. For example, devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz-7.125 GHZ) and FR2 (24.25 GHz-52.6 GHZ). It should be understood that although a portion of FR1 is greater than 6 GHZ, FR1 is often referred to (interchangeably) as a “Sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often referred to (interchangeably) as a “millimeter wave” band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz-300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band.
The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified an operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHZ-24.25 GHZ). Frequency bands falling within FR3 may inherit FR1 characteristics and/or FR2 characteristics, and thus may effectively extend features of FR1 and/or FR2 into mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHZ. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHZ-71 GHz), FR4 (52.6 GHZ-114.25 GHZ), and FR5 (114.25 GHZ-300 GHZ). Each of these higher frequency bands falls within the EHF band.
With the above examples in mind, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like, if used herein, may broadly represent frequencies that may be less than 6 GHZ, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like, if used herein, may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and/or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and/or FR5) may be modified, and techniques described herein are applicable to those modified frequency ranges.
In some aspects, the UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive, from a network node, C-WUS configuration information indicating a plurality of C-WUS formats, each C-WUS format of the plurality of C-WUS formats associated with respective information; and transmit, to the network node, a C-WUS associated with a C-WUS format of the plurality of C-WUS formats, the C-WUS including the respective information associated with the C-WUS format. Additionally, or alternatively, as described in more detail elsewhere herein, the communication manager 140 may receive, from a network node, a first SSB associated with a first NES of the network node, the first SSB including a first MIB indicating first information different from second information indicated in a second MIB included in a second SSB associated with a second NES of the network node; and communicate with the network node based at least in part on the first SSB. Additionally, or alternatively, the communication manager 140 may perform one or more other operations described herein.
In some aspects, the network node 110 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may transmit C-WUS configuration information indicating a plurality of C-WUS formats, each C-WUS format of the plurality of C-WUS formats associated with respective information; and receive, from a UE, a C-WUS associated with a C-WUS format of the plurality of C-WUS formats, the C-WUS including the respective information associated with the C-WUS format. Additionally, or alternatively, as described in more detail elsewhere herein, the communication manager 150 may transmit a first SSB associated with a first NES of the network node, the first SSB including a first MIB indicating first information different from second information indicated in a second MIB included in a second SSB associated with a second NES of the network node; and communicate with a UE based at least in part on the first SSB. Additionally, or alternatively, the communication manager 150 may perform one or more other operations described herein.
As indicated above,
At the network node 110, a transmit processor 220 may receive data, from a data source 212, intended for the UE 120 (or a set of UEs 120). The transmit processor 220 may select one or more modulation and coding schemes (MCSs) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from that UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS(s) selected for the UE 120 and may provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and/or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and/or the reference symbols, if applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems), shown as modems 232a through 232t. For example, each output symbol stream may be provided to a modulator component (shown as MOD) of a modem 232. Each modem 232 may use a respective modulator component to process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 may further use a respective modulator component to process (e.g., convert to analog, amplify, filter, and/or upconvert) the output sample stream to obtain a downlink signal. The modems 232a through 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas), shown as antennas 234a through 234t.
At the UE 120, a set of antennas 252 (shown as antennas 252a through 252r) may receive the downlink signals from the network node 110 and/or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems), shown as modems 254a through 254r. For example, each received signal may be provided to a demodulator component (shown as DEMOD) of a modem 254. Each modem 254 may use a respective demodulator component to condition (e.g., filter, amplify, downconvert, and/or digitize) a received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modems 254, may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, May provide decoded data for the UE 120 to a data sink 260, and may provide decoded control information and system information to a controller/processor 280. The term “controller/processor” may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and/or a CQI parameter, among other examples. In some examples, one or more components of the UE 120 may be included in a housing 284.

The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the network node 110 via the communication unit 294.
One or more antennas (e.g., antennas 234a through 234t and/or antennas 252a through 252r) may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and/or one or more antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, and/or one or more antenna elements coupled to one or more transmission and/or reception components, such as one or more components of
On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports that include RSRP, RSSI, RSRQ, and/or CQI) from the controller/processor 280. The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by the modems 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of the antenna(s) 252, the modem(s) 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, and/or the TX MIMO processor 266. The transceiver may be used by a processor (e.g., the controller/processor 280) and the memory 282 to perform aspects of any of the methods described herein (e.g., with reference to
At the network node 110, the uplink signals from UE 120 and/or other UEs may be received by the antennas 234, processed by the modem 232 (e.g., a demodulator component, shown as DEMOD, of the modem 232), detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and provide the decoded control information to the controller/processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and/or uplink communications.

As indicated above,
Deployment of communication systems, such as 5G NR systems, may be arranged in multiple manners with various components or constituent parts. In a 5G NR system, or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element, a base station, or a network equipment may be implemented in an aggregated or disaggregated architecture. For example, a base station (such as a Node B (NB), an evolved NB (eNB), an NR base station, a 5G NB, an access point (AP), a TRP, or a cell, among other examples), or one or more units (or one or more components) performing base station functionality, may be implemented as an aggregated base station (also known as a standalone base station or a monolithic base station) or a disaggregated base station. “Network entity” or “network node” may refer to a disaggregated base station, or to one or more units of a disaggregated base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).
An aggregated base station (e.g., an aggregated network node) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A disaggregated base station (e.g., a disaggregated network node) may be configured to utilize a protocol stack that is physically or logically distributed among two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, a CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed throughout one or multiple other network nodes. The DUs may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU also can be implemented as virtual units, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), among other examples.
Base station-type operation or network design may consider aggregation characteristics of base station functionality. For example, disaggregated base stations may be utilized in an IAB network, an open radio access network (O-RAN (such as the network configuration sponsored by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate scaling of communication systems by separating base station functionality into one or more units that can be individually deployed. A disaggregated base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented for at least one unit virtually, which can enable flexibility in network design. The various units of the disaggregated base station can be configured for wired or wireless communication with at least one other unit of the disaggregated base station.
Each of the units, including the CUs 310, the DUs 330, the RUs 340, as well as the Near-RT RICs 325, the Non-RT RICs 315, and the SMO Framework 305, may include one or more interfaces or be coupled with one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units, or an associated processor or controller providing instructions to one or multiple communication interfaces of the respective unit, can be configured to communicate with one or more of the other units via the transmission medium. In some examples, each of the units can include a wired interface, configured to receive or transmit signals over a wired transmission medium to one or more of the other units, and a wireless interface, which may include a receiver, a transmitter or transceiver (such as an RF transceiver), configured to receive or transmit signals, or both, over a wireless transmission medium to one or more of the other units.
In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions can include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, among other examples. Each control function can be implemented with an interface configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (for example, Central Unit-User Plane (CU-UP) functionality), control plane functionality (for example, Central Unit-Control Plane (CU-CP) functionality), or a combination thereof. In some implementations, the CU 310 can be logically split into one or more CU-UP units and one or more CU-CP units. A CU-UP unit can communicate bidirectionally with a CU-CP unit via an interface, such as the E1 interface when implemented in an O-RAN configuration. The CU 310 can be implemented to communicate with a DU 330, as necessary, for network control and signaling.
Each DU 330 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers depending, at least in part, on a functional split, such as a functional split defined by the 3GPP. In some aspects, the one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation, among other examples. In some aspects, the DU 330 may further host one or more low PHY layers, such as implemented by one or more modules for a fast Fourier transform (FFT), an inverse FFT (iFFT), digital beamforming, or physical random access channel (PRACH) extraction and filtering, among other examples. Each layer (which also may be referred to as a module) can be implemented with an interface configured to communicate signals with other layers (and modules) hosted by the DU 330, or with the control functions hosted by the CU 310.
Each RU 340 may implement lower-layer functionality. In some deployments, an RU 340, controlled by a DU 330, may correspond to a logical node that hosts RF processing functions or low-PHY layer functions, such as performing an FFT, performing an iFFT, digital beamforming, or PRACH extraction and filtering, among other examples, based on a functional split (for example, a functional split defined by the 3GPP), such as a lower layer functional split. In such an architecture, each RU 340 can be operated to handle over the air (OTA) communication with one or more UEs 120. In some implementations, real-time and non-real-time aspects of control and user plane communication with the RU(s) 340 can be controlled by the corresponding DU 330. In some scenarios, this configuration can enable each DU 330 and the CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.
The SMO Framework 305 may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO Framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operations and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO Framework 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 390) to perform network element life cycle management (such as to instantiate virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements can include, but are not limited to, CUs 310, DUs 330, RUs 340, non-RT RICs 315, and Near-RT RICs 325. In some implementations, the SMO Framework 305 can communicate with a hardware aspect of a 4G RAN, such as an open eNB (O-eNB) 311, via an O1 interface. Additionally, in some implementations, the SMO Framework 305 can communicate directly with each of one or more RUs 340 via a respective O1 interface. The SMO Framework 305 also may include a Non-RT RIC 315 configured to support functionality of the SMO Framework 305.
The Non-RT RIC 315 may be configured to include a logical function that enables non-real-time control and optimization of RAN elements and resources, Artificial Intelligence/Machine Learning (AI/ML) workflows including model training and updates, or policy-based guidance of applications/features in the Near-RT RIC 325. The Non-RT RIC 315 may be coupled to or communicate with (such as via an A1 interface) the Near-RT RIC 325. The Near-RT RIC 325 may be configured to include a logical function that enables near-real-time control and optimization of RAN elements and resources via data collection and actions over an interface (such as via an E2 interface) connecting one or more CUs 310, one or more DUs 330, or both, as well as an O-eNB, with the Near-RT RIC 325.
In some implementations, to generate AI/ML models to be deployed in the Near-RT RIC 325, the Non-RT RIC 315 may receive parameters or external enrichment information from external servers. Such information may be utilized by the Near-RT RIC 325 and may be received at the SMO Framework 305 or the Non-RT RIC 315 from non-network data sources or from network functions. In some examples, the Non-RT RIC 315 or the Near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the Non-RT RIC 315 may monitor long-term trends and patterns for performance and employ AI/ML models to perform corrective actions through the SMO Framework 305 (such as reconfiguration via an O1 interface) or via creation of RAN management policies (such as A1 interface policies).

During each of the DRX on durations 410 (for example, the active times), the UE 120 may monitor a downlink control channel (for example, a PDCCH). For example, the UE 120 may monitor the PDCCH for downlink control information (DCI) pertaining to the UE 120. If the UE 120 does not detect and/or successfully decode any PDCCH communications intended for the UE 120 during the DRX on duration 410 (as shown at 425 in

As indicated above,
One potential technique to increase energy efficiency in a RAN may be to enable cell DRX. In some aspects, a network node may transmit (for example, to one or more UEs) a cell DRX configuration to configure a cell DRX cycle. The cell DRX configuration may configure time periods in which a network node does not receive transmissions from UEs in the cell, which allows the network node to enter a sleep state. The cell DRX configuration may configure discontinuous transmission (DTX) for one or more UEs in the cell. The cell DRX configuration may also be referred to as a DTX/DRX configuration or a DTX configuration for a UE. The cell DRX configuration may have similar characteristics as a DRX configuration that may be configured for a UE. For example, the cell DRX cycle may include a cell DRX on duration (or active time), during which the network node is awake and in an active state, and a cell DRX off duration (or inactive time), during which the network node is configured to be in a sleep state. The network node may not transmit or receive channels or signals while in the sleep state. For example, the network node may not receive or monitor for uplink channel communications, random access channel (RACH) communications, or uplink reference signals, among other examples, during the cell DRX inactive time.
In some examples, the cell DRX configuration may be activated during times of the day (for example, off-peak times) in which there is no traffic or a light traffic load in the cell. However, the network node may still be required to periodically broadcast signals and/or channels, such as SSBs and system information (SI). Furthermore, the network node may still need to periodically monitor PRACH occasions for possible RACH or small data transmission (SDT) from a UE that is not is an RRC connected mode. All such periodic transmission and monitoring requires the network node to be in the active state, and thus limits network power savings that can be achieved from cell DRX. In some examples, if the network node knows that there are no connected UEs or a light traffic load in the cell, the network node may stop or slow down periodic transmission and/or periodic monitoring to achieve network power savings. However, in some cases, the network node may not be aware of whether one or more UEs need to switch to a connected state (for example, RRC connected mode) or perform some SDT so the network node can transition to the active state. In some aspects, such UEs may proactively wake up the network node by sending a C-WUS. The C-WUS may be a physical layer signal, such as a PRACH or scheduling request (SR).
As shown in
As indicated above,
As shown in
In some aspects, the network node 110 may transmit the C-WUS configuration information via layer 3 (L3), layer 2 (L2), or layer 1 (L1) signaling (for example, in an RRC message, a MAC control element (MAC-CE), or DCI, respectively) to the UE 120 or to a group of UEs including the UE 120. In such examples, the network node 110 may separately signal the C-WUS configuration information to each UE or group of UEs in the cell. In some aspects, the network node 110 may broadcast the C-WUS configuration information to UEs in the cell using L1, L2, or L3 signaling. For example, the C-WUS configuration information may be included in an SIB1, a MIB, one or more other SIBs, or a combination thereof (for example, a combination of the MIB and the SIB1). In some aspects, the C-WUS configuration information (or a portion of the C-WUS configuration information) may be indicated in a MIB included in a simplified version of an SSB (e.g., the first SSB described in connection with FIG. 7) associated with a certain NES of the network node 110, as discussed elsewhere herein.
In some aspects, the C-WUS may be a sequence (for example, a baseband sequence) transmitted by a UE (e.g., the UE 120) to wake up the network node 110 from a sleep state. In some aspects, the C-WUS may be a sequence transmitted via a physical uplink control channel (PUCCH). For example, the sequence may be transmitted via a PUCCH format 0 communication. In some aspects, a C-WUS associated with a certain C-WUS format may include a sequence transmitted together with a payload that includes the respective information associated with that C-WUS format. In some aspects, a cell-specific sequence may be configured (e.g., indicated in the C-WUS configuration information) for the C-WUS. In this case, C-WUSs associated with different C-WUS formats may include the cell-specific sequence transmitted with different payloads (e.g., different bits representing different sets of information). In some aspects, different C-WUS formats may be associated with different sequences. For example, the C-WUS configuration information may indicate different sequences and/or different cyclic shifts (CSs) for different C-WUS formats of the multiple C-WUS formats.
In some aspects, the C-WUS configuration information may indicate one or more C-WUS monitoring occasions. The C-WUS monitoring occasions may correspond to active times in a cell DRX cycle, during which the network node 110 may switch from a sleep state to an active state to monitor for C-WUS transmissions. The C-WUS configuration information may indicate respective C-WUS resources associated with each of one or more C-WUS monitoring occasions. In some aspects, different C-WUS monitoring occasions may be configured for different C-WUS formats of the multiple C-WUS formats. In some other aspects, the same configured C-WUS monitoring occasions may be used by the UE 120 to transmit a C-WUS associated with any C-WUS format. In some aspects, one or more of the C-WUS formats may be associated with multi-stage C-WUS transmission. In this case, each C-WUS monitoring occasion configured for a multi-stage C-WUS transmission may include respective monitoring occasions for each of multiple stages in the multi-stage C-WUS transmission. For example, a C-WUS monitoring occasion may include a first stage monitoring occasion associated with a first stage of the C-WUS transmission and a second stage monitoring occasion associated with a second stage of the C-WUS transmission.
In some aspects, the C-WUS configuration information may indicate one or more C-WUS triggering conditions that trigger the UE 120 to transmit the C-WUS in a C-WUS monitoring occasion. For example, the one or more triggering conditions may include at least one of an uplink buffer status report (BSR) threshold, an uplink delay status report (DSR) threshold, an energy level threshold, a charging rate threshold, or a discharging rate threshold, among other examples.
In some aspects, the C-WUS configuration information may indicate the multiple C-WUS formats, and each C-WUS format of the multiple C-WUS formats may be associated with a respective set of information. For example, each C-WUS format may be configured with a set of information bits to indicate the respective set of information. In some aspects, the respective set of information associated with each C-WUS format includes information bits in addition to the C-WUS sequence associated with indicating that the network node 110 is to wake up from the sleep state and remain in the active state. In some aspects, the C-WUS configuration information may indicate the respective set of information associated with each C-WUS format. That is, the C-WUS configuration information may indicate, for each C-WUS format, which information bits are to be included in a C-WUS associated with that C-WUS format. Examples of different information that may be associated with one or more different C-WUS formats are described in greater detail in connection with reference number 615. In some aspects, the different sets of information associated with the different C-WUS formats may include different combinations of the information discussed in connection with reference number 615
As further shown in
In some other aspects, the UE 120 may select the C-WUS format, from the multiple C-WUS formats indicated in the C-WUS configuration information, for the C-WUS to be transmitted by the UE 120. For example, the UE 120 may select the C-WUS format based at least in part on the respective set of information associated with the C-WUS format. That is, the UE 120 may select information to transmit with the C-WUS transmission, and the UE 120 may select the C-WUS format, from the multiple C-WUS formats, for which the respective set of information includes the selected information to be transmitted with the C-WUS transmission. For example, in a case in which an uplink buffer of the UE 120 includes uplink traffic to be transmitted by the UE 120, the UE 120 may determine to transmit information relating to the uplink traffic, such as a BSR and/or a DSR, with the C-WUS transmission. In such an examples, the UE 120 may select, from the multiple C-WUS formats indicated in the C-WUS configuration information, a C-WUS format that includes bits for indicating the BSR and/or the DSR associated with the uplink traffic in the uplink buffer of the UE 120.
As further shown in
In some aspects, the UE 120 may transmit the C-WUS based at least in part on uplink traffic (or sidelink traffic) to be transmitted by the UE 120 arriving in an uplink buffer (or a sidelink buffer) of the UE 120. For example, the UE 120 may transmit the C-WUS after the uplink traffic (or sidelink traffic) has arrived in the uplink buffer (or the sidelink buffer). In some aspects, the UE 120 may transmit the C-WUS in connection with a determination that a triggering condition for transmitting the C-WUS is satisfied. In some examples, the triggering condition may be satisfied in connection with a size of an uplink buffer (e.g., a size or amount of uplink data to be transmitted by the UE 120) satisfying a BSR threshold. For example, the UE 120 may transmit the C-WUS once the uplink buffer is greater than or equal to the BSR threshold. In some examples, the UE 120 may generate a DSR that indicates a waiting time (Twait) for packets in the uplink buffer of the UE 120 and the remaining packet delay budget (PDB) for the packets in the uplink buffer of the UE 120. In this case, the triggering condition may be satisfied in connection with a determination that the waiting time (Twait), or a comparison of the waiting time (Twait) and the PDB, satisfies a DSR threshold (e.g., equals or is greater than a DSR threshold). In some examples, the triggering condition may be satisfied based at least in part on an energy level (e.g., a power level) of the UE 120 satisfying an energy level threshold (e.g., the energy level equaling or being greater than the energy level threshold). In some examples, the triggering condition may be satisfied based at least in part on a charging rate of the UE 120 satisfying a charging rate threshold (e.g., the charging rate failing to exceed the charging rate threshold). In some examples, the triggering condition may be satisfied based at least in part on a discharging rate of the UE 120 satisfying a discharging rate threshold (e.g., the discharging rate equaling or being greater than the discharging rate threshold).
In some aspects, the UE 120 may transmit the C-WUS in multiple stages. In some aspects, the information included in the C-WUS (e.g., the respective set of information associated with the C-WUS format of the C-WUS) may be transmitted over multiple C-WUS transmissions in the multiple stages. For example, as shown in
If the network node 110 receives the first stage C-WUS in the first stage monitoring occasion, the network node 110 may then monitor the second stage monitoring occasion to receive the second stage C-WUS. If the network node 110 does not receive the first stage C-WUS in the first stage monitoring occasion, the network node 110 may refrain from monitoring the second stage monitoring occasion, which may allow the network node 110 to return to a sleep state prior to an end of the C-WUS monitoring occasion, and thus may increase network energy savings. As shown by reference number 640, in some aspects, the UE 120 may transmit the first stage C-WUS and the second stage C-WUS in back-to-back transmissions (e.g., in consecutive slots and/or symbols) in a C-WUS monitoring occasion. Although
In some aspects, as shown in
As show by reference number 650, in some aspects, the UE 120 may transmit the indication of the C-WUS format in a first stage monitoring occasion of a C-WUS monitoring occasion, and the UE 120 may transmit the C-WUS including the information associated with the C-WUS format in a second stage monitoring occasion (or multiple second stage monitoring occasions) of the C-WUS monitoring occasion. In this case, the network node 110 may monitor the first stage monitoring occasion. If the network node 110 receives the indication of the C-WUS format in the first stage monitoring occasion, the network node 110 may then monitor the second stage monitoring occasion to receive the C-WUS and the information associated with the C-WUS format. If the network node 110 does not receive the indication of the C-WUS format in the first stage monitoring occasion, the network node 110 may refrain from monitoring the second stage monitoring occasion, which may allow the network node 110 to return to a sleep state prior to an end of the C-WUS monitoring occasion, and thus may increase network energy savings. As shown by reference number 660, in some aspects, the UE 120 may transmit the indication of the C-WUS format in the first stage and the C-WUS including the information associated with the C-WUS format in the second stage (or in multiple second stages) in back-to-back transmissions (e.g., in consecutive slots and/or symbols) in a C-WUS monitoring occasion.
In some aspects, the information associated with the C-WUS format and included in the C-WUS (e.g., transmitted in one or more stages) may include information relating to uplink traffic in an uplink buffer of a UE 120. For example, the information associated with the C-WUS format may include an uplink BSR and/or an uplink DSR. Additionally, or alternatively, the information associated with the C-WUS format may include a low-resolution indication associated with the BSR or the DSR. For example, the information associated with the C-WUS format may include an indication (e.g., a one bit indication) of whether a threshold associated with the BSR is satisfied (e.g., a size of the uplink buffer satisfies the threshold associated with the BSR) and/or an indication (e.g., a one bit indication) of whether a threshold associated with the DSR is satisfied (e.g., whether a waiting time, a remaining PDB, or a comparison of the waiting time and the remaining PDB satisfies the threshold associated with the DSR). In this case, the threshold associated with the BSR and/or the threshold associated with the DSR may be based at least in part on configuration information received from the network node 110 (e.g., indicated in the C-WUS configuration information or other configuration information), an NES of the network node 110, or an energy state (or power state) of the UE 120.
In some aspects, the information associated with the C-WUS format and included in the C-WUS may include uplink and/or sidelink traffic statistics including one or more traffic types for uplink and/or sidelink traffic or one or more logical channel group (LCG) identifiers (IDs) corresponding to one or more LCGs associated with the uplink and/or sidelink traffic. For example, the information associated with the C-WUS format may include at least one of an indication of one or more traffic types associated with uplink or sidelink packets to be transmitted by the UE 120 or an indication of one or more LCG IDs associated with the uplink or sidelink packets to be transmitted by the UE 120. Additionally, or alternatively, the information associated with the C-WUS format and included in the C-WUS may include timing information associated with the uplink and/or sidelink traffic. For example, the timing information may include at least one of an indication of a remaining PDB associated with a highest priority packet of the uplink or sidelink traffics to be transmitted by the UE 120, an indication of a minimum remaining PDB across all of the uplink or sidelink packets to be transmitted by the UE 120, or an indication of a highest priority associated with the uplink or sidelink packets to be transmitted by the UE 120.
In some aspects, the information associated with the C-WUS format and included in the C-WUS may include a scheduling request for a sidelink communication. For example, the information associated with the C-WUS format may include a bit field for indicating whether the UE 120 requests a sidelink scheduling request, and the UE 120 may indicate, in the bit field, a bit value associated with requesting a sidelink scheduling request.
In some aspects, the information associated with the C-WUS format and included in the C-WUS may include a SIB1 request and an indication of a time offset associated with the SIB1 request. For example, the time offset associated with the SIB1 request may be a minimum time offset between the C-WUS transmission and the transmission of the SIB1 by the network node 110. In some examples, in a case in which the UE 120 is an energy harvesting device that charges by harvesting energy from RF signals transmitted by the network node 110, the UE 120 may indicate the minimum time offset, between the C-WUS transmission and the transmission of the SIB1, based at least in part on an amount of time for the UE 120 (or another energy harvesting device) to charge before receiving the SIB 1.
In some aspects, the information associated with the C-WUS format and included in the C-WUS may include information relating to a positioning or sensing procedure. For example, information included in the C-WUS may include an indication of a positioning or sensing request. In some examples, the information included in the C-WUS may further include an indication of a time offset associated with the positioning or sensing request. For example, the time offset associated with the positioning or sensing request may be a time offset between the C-WUS transmission and a requested start time for a positioning or sensing procedure associated with the positioning or sensing request. Additionally, or alternatively, the information included in the C-WUS may further include (e.g., in addition to an indication of a positioning or sensing request) an indication of at least one of a priority or a latency (e.g., a latency requirement) associated with the positioning or sensing request.
In some aspects, the information associated with the C-WUS format and included in the C-WUS may include at least one of a CSI report for a Uu link (e.g., a link between the network node 110 and the UE 120) or a CSI report for a sidelink (e.g., between the UE 120 and another UE). In this case, the UE 120 may buffer the CSI report(s) (e.g., for the Uu link and/or the sidelink) until the C-WUS transmission time (e.g., in the C-WUS monitoring occasion). In some aspects, the information associated with the C-WUS format and included in the C-WUS may include a power headroom report (PHR) that indicates a PHR associated with the UE 120.
In some aspects, the information associated with the C-WUS format and included in the C-WUS may include an energy request associated with energy harvesting to be performed by the UE 120. For example, in a case in which the UE 120 is an energy harvesting device and the network node 110 supports wireless energy transfer, the UE 120 may indicate, in the information associated with the C-WUS format, a request for transmission, by the network node 110, of a signal to be used for energy harvesting by the UE 120.
In some aspects, the information associated with the C-WUS format and included in the C-WUS may include information associated with a WUR of the UE 120 and/or LP-WUS transmission by the network node 110. For example, the information associated with the C-WUS format may include an indication of a configuration of an LP-WUS associated with a WUR of the UE 120. In this case, the indication of the configuration of the LP-WUS may indicate a selected configuration (e.g., from multiple LP-WUS configurations) of the LP-WUS to be transmitted by the network node 110 and received by the WUR (e.g., a low power WUR) of the UE 120 to wake up a main radio (MR) of the UE 120 from a sleep state to an active state. Additionally, or alternatively, the information associated with the C-WUS format may include an activation indication associated with a LP-WUS. For example, the activation indication may activate an LP-WUS so that the network node 110 transmits the LP-WUS based on LP-WUS compatibility of the WUR of the UE 120. In some examples, the information associated with the C-WUS format may include configurations for one or more low power synchronization signals (LP-SSs) associated with synchronizing the WUR of the UE 120 (e.g., synchronizing the LP-WUS to be received by the WUR of the UE 120). Additionally, or alternatively, the information associated with the C-WUS format may include configurations for one or more low power reference signals (LP-RSs) for radio resource management (RRM) measurements performed by the WUR of the UE 120 and/or configurations for one or more preamble signals associated with the WUR of the UE 120. In some examples, the information associated with the C-WUS format may include an indication of whether the LP-WUS to be transmitted by the network node 110 supports SSB configuration for the UE 120.
In some aspects, the information associated with the C-WUS format and included in the C-WUS may include information associated with CG uplink communications and/or SPS downlink communications. For example, the information associated with the C-WUS format may include an indication of one or more preferred CG configurations for the UE 120 and/or an indication of one or more preferred SPS configurations for the UE 120. In this case, the information associated with the C-WUS format may indicate a preferred CG configuration or a template of best (e.g., preferred) CG configurations, and/or the information associated with the C-WUS format may indicate a preferred SPS configuration or a template of best (e.g., preferred) SPS configurations.

In some aspects, the information associated with the C-WUS format and included in the C-WUS may include an indication of an SSB index selected by the UE 120. For example, the UE 120 may change an SSB index (e.g., based on SSB measurements performed by the UE 120), from a previously indicated SSB index, prior to transmitting the C-WUS (e.g., prior to the DRX active time of the network node 110). In this case, the UE 120 may select a new SSB index, as compared to a latest SSB index indicated by the UE 120, and the UE 120 may indicate the selected SSB index in the information included in the C-WUS to inform the network node 110 of the selected SSB index (e.g., and the beam information associated with the selected SSB index). In some aspects, the information associated with the C-WUS format and included in the C-WUS may include an indication of capability of the UE 120.

For example, the first information indicated in the first MIB of the first SSB may include an indication of whether the network node 110 supports WUR-based UEs in the current NES (e.g., the first NES) of the network node 110. Additionally, or alternatively, the first information indicated in the first MIB of the first SSB may include an indication of whether WUR-based UEs are barred from using the WUR.
