Description

FIELD OF THE DISCLOSURE

Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for power control configuration.

BACKGROUND

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 base stations that support communication for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink communications and uplink communications. “Downlink” (or “DL”) refers to a communication link from the base station to the UE, and “uplink” (or “UL”) refers to a communication link from the UE to the base station.

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.

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.

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 New Radio (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).

FIG. 1 is a diagram illustrating an example of a wireless network 100, in accordance with the present disclosure. The wireless network 100 may be or may include elements of a 5G (e.g., NR) network and/or a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network 100 may include one or more base stations 110 (shown as a BS 110a, a BS 110b, a BS 110c, and a BS 110d), a user equipment (UE) 120 or multiple UEs 120 (shown as a UE 120a, a UE 120b, a UE 120c, a UE 120d, and a UE 120e), and/or other network entities. A base station 110 is an entity that communicates with UEs 120. A base station 110 (sometimes referred to as a BS) 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, and/or a transmission reception point (TRP). Each base station 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 base station 110 and/or a base station subsystem serving this coverage area, depending on the context in which the term is used.

A base station 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 subscription. 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 base station 110 for a macro cell may be referred to as a macro base station. A base station 110 for a pico cell may be referred to as a pico base station. A base station 110 for a femto cell may be referred to as a femto base station or an in-home base station. In the example shown in FIG. 1, the BS 110a may be a macro base station for a macro cell 102a, the BS 110b may be a pico base station for a pico cell 102b, and the BS 110c may be a femto base station for a femto cell 102c. A base station may support one or multiple (e.g., three) cells.

In some examples, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a base station 110 that is mobile (e.g., a mobile base station). In some examples, the base stations 110 may be interconnected to one another and/or to one or more other base stations 110 or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces, such as a direct physical connection or a virtual network, using any suitable transport network.

The wireless network 100 may include one or more relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a base station 110 or a UE 120) and send a transmission of the data to a downstream station (e.g., a UE 120 or a base station 110). A relay station may be a UE 120 that can relay transmissions for other UEs 120. In the example shown in FIG. 1, the BS 110d (e.g., a relay base station) may communicate with the BS 110a (e.g., a macro base station) and the UE 120d in order to facilitate communication between the BS 110a and the UE 120d. A base station 110 that relays communications may be referred to as a relay station, a relay base station, a relay, or the like.

The wireless network 100 may be a heterogeneous network that includes base stations 110 of different types, such as macro base stations, pico base stations, femto base stations, relay base stations, or the like. These different types of base stations 110 may have different transmit power levels, different coverage areas, and/or different impacts on interference in the wireless network 100. For example, macro base stations may have a high transmit power level (e.g., 5 to 40 watts) whereas pico base stations, femto base stations, and relay base stations 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 base stations 110 and may provide coordination and control for these base stations 110. The network controller 130 may communicate with the base stations 110 via a backhaul communication link. The base stations 110 may communicate with one another directly or indirectly via a wireless or wireline backhaul communication link.

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, and/or any other suitable device that is configured to communicate via a wireless 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, a drone, a remote device, a sensor, a meter, a monitor, and/or a location tag, that may communicate with a base station, 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 120e) may communicate directly using one or more sidelink channels (e.g., without using a base station 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 base station 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 signaling identifying a plurality of power control configurations, wherein each power control configuration, of the plurality of power control configurations, includes one or more power control parameters; and transmit uplink traffic using a power control configuration, of the plurality of power control configurations, selected based at least in part on a channel type. The communication manager 140 may receive, from a base station, information configuring a set of resources associated with a set of pathloss reference signals; identify a pathloss reference signal, of the set of pathloss reference signals, based at least in part on a UE capability; and communicate with the base station based at least in part on identifying the pathloss reference signal. Additionally, or alternatively, the communication manager 140 may perform one or more other operations described herein.

In some aspects, the base station 110 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may transmit signaling identifying a plurality of power control configurations, wherein each power control configuration, of the plurality of power control configurations, includes one or more power control parameters; and receive uplink traffic transmitted using a power control configuration, of the plurality of power control configurations, associated with a channel type. The communication manager 150 may transmit, to a UE, information configuring a set of resources associated with a set of pathloss reference signals; configure a pathloss reference signal, of the set of pathloss reference signals, for the UE based at least in part on a UE capability; and communicate with the UE based at least in part on configuring the pathloss reference signal. Additionally, or alternatively, the communication manager 150 may perform one or more other operations described herein.

As indicated above, FIG. 1 is provided as an example. Other examples may differ from what is described with regard to FIG. 1.

FIG. 2 is a diagram illustrating an example 200 of a base station 110 in communication with a UE 120 in a wireless network 100, in accordance with the present disclosure. The base station 110 may be equipped with a set of antennas 234a through 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a through 252r, such as R antennas (R≥1).

At the base station 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 base station 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 base station 110 and/or other base stations 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 a communication unit 294, a controller/processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 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 FIG. 2.

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 base station 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 FIGS. 5-12).

At the base station 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 base station 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and/or uplink communications. In some examples, the modem 232 of the base station 110 may include a modulator and a demodulator. In some examples, the base station 110 includes a transceiver. The transceiver may include any combination of the antenna(s) 234, the modem(s) 232, the MIMO detector 236, the receive processor 238, the transmit processor 220, and/or the TX MIMO processor 230. The transceiver may be used by a processor (e.g., the controller/processor 240) and the memory 242 to perform aspects of any of the methods described herein (e.g., with reference to FIGS. 5-12).

The controller/processor 240 of the base station 110, the controller/processor 280 of the UE 120, and/or any other component(s) of FIG. 2 may perform one or more techniques associated with power control configuration, as described in more detail elsewhere herein. For example, the controller/processor 240 of the base station 110, the controller/processor 280 of the UE 120, and/or any other component(s) of FIG. 2 may perform or direct operations of, for example, process 700 of FIG. 7, process 800 of FIG. 8, process 900 of FIG. 9, process 1000 of FIG. 10, and/or other processes as described herein. The memory 242 and the memory 282 may store data and program codes for the base station 110 and the UE 120, respectively. In some examples, the memory 242 and/or the memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and/or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, and/or interpreting) by one or more processors of the base station 110 and/or the UE 120, may cause the one or more processors, the UE 120, and/or the base station 110 to perform or direct operations of, for example, process 700 of FIG. 7, process 800 of FIG. 8, process 900 of FIG. 9, process 1000 of FIG. 10, and/or other processes as described herein. In some examples, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and/or interpreting the instructions, among other examples.

In some aspects, the UE 120 includes means for receiving signaling identifying a plurality of power control configurations, wherein each power control configuration, of the plurality of power control configurations, includes one or more power control parameters; and/or means for transmitting uplink traffic using a power control configuration, of the plurality of power control configurations, selected based at least in part on a channel type. In some aspects, the UE 120 includes means for receiving, from a base station, information configuring a set of resources associated with a set of pathloss reference signals; means for identifying a pathloss reference signal, of the set of pathloss reference signals, based at least in part on a UE capability; and/or means for communicating with the base station based at least in part on identifying the pathloss reference signal. The means for the UE 120 to perform operations described herein may include, for example, one or more of communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller/processor 280, or memory 282.

In some aspects, the base station 110 includes means for transmitting signaling identifying a plurality of power control configurations, wherein each power control configuration, of the plurality of power control configurations, includes one or more power control parameters; and/or means for receiving uplink traffic transmitted using a power control configuration, of the plurality of power control configurations, associated with a channel type. In some aspects, the base station 110 includes means for transmitting, to a UE, information configuring a set of resources associated with a set of pathloss reference signals; means for configuring a pathloss reference signal, of the set of pathloss reference signals, for the UE based at least in part on a UE capability; and/or means for communicating with the UE based at least in part on configuring the pathloss reference signal. The means for the base station to perform operations described herein may include, for example, one or more of communication manager 150, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller/processor 240, memory 242, or scheduler 246.

While blocks in FIG. 2 are illustrated as distinct components, the functions described above with respect to the blocks may be implemented in a single hardware, software, or combination component or in various combinations of components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and/or the TX MIMO processor 266 may be performed by or under the control of the controller/processor 280.

As indicated above, FIG. 2 is provided as an example. Other examples may differ from what is described with regard to FIG. 2.

FIG. 3 is a diagram illustrating an example 300 of physical channels and reference signals in a wireless network, in accordance with the present disclosure. As shown in FIG. 3, downlink channels and downlink reference signals may carry information from a base station 110 to a UE 120, and uplink channels and uplink reference signals may carry information from a UE 120 to a base station 110.

As shown, a downlink channel may include a physical downlink control channel (PDCCH) that carries downlink control information (DCI), a physical downlink shared channel (PDSCH) that carries downlink data, or a physical broadcast channel (PBCH) that carries system information, among other examples. PDSCH communications may be scheduled by PDCCH communications. As further shown, an uplink channel may include a physical uplink control channel (PUCCH) that carries uplink control information (UCI), a physical uplink shared channel (PUSCH) that carries uplink data, or a physical random access channel (PRACH) used for initial network access, among other examples. The UE 120 may transmit acknowledgement (ACK) or negative acknowledgement (NACK) feedback (e.g., ACK/NACK feedback or ACK/NACK information) in UCI on the PUCCH and/or the PUSCH.

As further shown, a downlink reference signal may include a synchronization signal block (SSB), a channel state information (CSI) reference signal (CSI-RS), a DMRS, a positioning reference signal (PRS), or a phase tracking reference signal (PTRS), among other examples. As also shown, an uplink reference signal may include a sounding reference signal (SRS), a DMRS, or a PTRS, among other examples.

An SSB may carry information used for initial network acquisition and synchronization, such as a PSS, an SSS, a PBCH, and a PBCH DMRS. An SSB is sometimes referred to as a synchronization signal/PBCH (SS/PBCH) block. The base station 110 may transmit multiple SSBs on multiple corresponding beams, and the SSBs may be used for beam selection.

A CSI-RS may carry information used for downlink channel estimation (e.g., downlink CSI acquisition), which may be used for scheduling, link adaptation, or beam management, among other examples. The base station 110 may configure a set of CSI-RSs for the UE 120, and the UE 120 may measure the configured set of CSI-RSs.

Based at least in part on the measurements, the UE 120 may perform channel estimation and may report channel estimation parameters to the base station 110 (e.g., in a CSI report), such as a CQI, a precoding matrix indicator (PMI), a CSI-RS resource indicator (CRI), a layer indicator (LI), a rank indicator (RI), or an RSRP, among other examples. The base station 110 may use the CSI report to select transmission parameters for downlink communications to the UE 120, such as a number of transmission layers (e.g., a rank), a precoding matrix (e.g., a precoder), an MCS, or a refined downlink beam (e.g., using a beam refinement procedure or a beam management procedure), among other examples.

A DMRS may carry information used to estimate a radio channel for demodulation of an associated physical channel (e.g., PDCCH, PDSCH, PBCH, PUCCH, or PUSCH). The design and mapping of a DMRS may be specific to a physical channel for which the DMRS is used for estimation. DMRSs are UE-specific, can be beamformed, can be confined in a scheduled resource (e.g., rather than transmitted on a wideband), and can be transmitted only when necessary. As shown, DMRSs are used for both downlink communications and uplink communications.

A PTRS may carry information used to compensate for oscillator phase noise. Typically, the phase noise increases as the oscillator carrier frequency increases. Thus, PTRS can be utilized at high carrier frequencies, such as millimeter wave frequencies, to mitigate phase noise. The PTRS may be used to track the phase of the local oscillator and to enable suppression of phase noise and common phase error (CPE). As shown, PTRSs are used for both downlink communications (e.g., on the PDSCH) and uplink communications (e.g., on the PUSCH).

A PRS may carry information used to enable timing or ranging measurements of the UE 120 based on signals transmitted by the base station 110 to improve observed time difference of arrival (OTDOA) positioning performance. For example, a PRS may be a pseudo-random Quadrature Phase Shift Keying (QPSK) sequence mapped in diagonal patterns with shifts in frequency and time to avoid collision with cell-specific reference signals and control channels (e.g., a PDCCH). In general, a PRS may be designed to improve detectability by the UE 120, which may need to detect downlink signals from multiple neighboring base stations in order to perform OTDOA-based positioning. Accordingly, the UE 120 may receive a PRS from multiple cells (e.g., a reference cell and one or more neighbor cells), and may report a reference signal time difference (RSTD) based on OTDOA measurements associated with the PRSs received from the multiple cells. The base station 110 may then calculate a position of the UE 120 based on the RSTD measurements reported by the UE 120.

An SRS may carry information used for uplink channel estimation, which may be used for scheduling, link adaptation, precoder selection, or beam management, among other examples. The base station 110 may configure one or more SRS resource sets for the UE 120, and the UE 120 may transmit SRSs on the configured SRS resource sets. An SRS resource set may have a configured usage, such as uplink CSI acquisition, downlink CSI acquisition for reciprocity-based operations, uplink beam management, among other examples. The base station 110 may measure the SRSs, may perform channel estimation based at least in part on the measurements, and may use the SRS measurements to configure communications with the UE 120.

Some reference signals may be used as pathloss reference signals (PL-RSs). For example, a base station may transmit a reference signal with a fixed power value and may transmit information identifying the power of the reference signal that the base station is transmitting. The UE may decode the reference signal and measure a power of the reference signal. In this case, the UE may determine a path loss between the UE and the base station based at least in part on the transmit power of the reference signal and the measured received power of the reference signal. Using the path loss and information identifying a maximum allowable transmit power, the UE may determine a transmit power that the UE can use to avoid exceeding the maximum allowable transmit power in the presence of the path loss between the UE and the base station. This procedure may be termed an “open loop power control process.” Other power control processes may be possible, such as a closed loop power control process (e.g., in which a feedback loop is used to determine a transmit power).

As indicated above, FIG. 3 is provided as an example. Other examples may differ from what is described with regard to FIG. 3.

FIG. 4 is a diagram illustrating an example 400 of using beams for communications between a base station and a UE, in accordance with the present disclosure. As shown in FIG. 4, a base station 110 and a UE 120 may communicate with one another.

The base station 110 may transmit to UEs 120 located within a coverage area of the base station 110. The base station 110 and the UE 120 may be configured for beamformed communications, where the base station 110 may transmit in the direction of the UE 120 using a directional BS transmit beam, and the UE 120 may receive the transmission using a directional UE receive beam. Each BS transmit beam may have an associated beam ID, beam direction, or beam symbols, among other examples. The base station 110 may transmit downlink communications via one or more BS transmit beams 405.

The UE 120 may attempt to receive downlink transmissions via one or more UE receive beams 410, which may be configured using different beamforming parameters at receive circuitry of the UE 120. The UE 120 may identify a particular BS transmit beam 405, shown as BS transmit beam 405-A, and a particular UE receive beam 410, shown as UE receive beam 410-A, that provide relatively favorable performance (for example, that have a best channel quality of the different measured combinations of BS transmit beams 405 and UE receive beams 410). In some examples, the UE 120 may transmit an indication of which BS transmit beam 405 is identified by the UE 120 as a preferred BS transmit beam, which the base station 110 may select for transmissions to the UE 120. The UE 120 may thus attain and maintain a beam pair link (BPL) with the base station 110 for downlink communications (for example, a combination of the BS transmit beam 405-A and the UE receive beam 410-A), which may be further refined and maintained in accordance with one or more established beam refinement procedures.

A downlink beam, such as a BS transmit beam 405 or a UE receive beam 410, may be associated with a transmission configuration indication (TCI) state. A TCI state may indicate a directionality or a characteristic of the downlink beam, such as one or more QCL properties of the downlink beam. A QCL property may include, for example, a Doppler shift, a Doppler spread, an average delay, a delay spread, or spatial receive parameters, among other examples. In some examples, each BS transmit beam 405 may be associated with an SSB, and the UE 120 may indicate a preferred BS transmit beam 405 by transmitting uplink transmissions in resources of the SSB that are associated with the preferred BS transmit beam 405. A particular SSB may have an associated TCI state (for example, for an antenna port or for beamforming). The base station 110 may, in some examples, indicate a downlink BS transmit beam 405 based at least in part on antenna port QCL properties that may be indicated by the TCI state. A TCI state may be associated with one downlink reference signal set (for example, an SSB and an aperiodic, periodic, or semi-persistent CSI-RS) for different QCL types (for example, QCL types for different combinations of Doppler shift, Doppler spread, average delay, delay spread, or spatial receive parameters, among other examples). In cases where the QCL type indicates spatial receive parameters, the QCL type may correspond to analog receive beamforming parameters of a UE receive beam 410 at the UE 120. Thus, the UE 120 may select a corresponding UE receive beam 410 from a set of BPLs based at least in part on the base station 110 indicating a BS transmit beam 405 via a TCI indication.

The base station 110 may maintain a set of activated TCI states for downlink shared channel transmissions and a set of activated TCI states for downlink control channel transmissions. The set of activated TCI states for downlink shared channel transmissions may correspond to beams that the base station 110 uses for downlink transmission on a PDSCH. The set of activated TCI states for downlink control channel communications may correspond to beams that the base station 110 may use for downlink transmission on a PDCCH or in a control resource set (CORESET). The UE 120 may also maintain a set of activated TCI states for receiving the downlink shared channel transmissions and the CORESET transmissions. If a TCI state is activated for the UE 120, then the UE 120 may have one or more antenna configurations based at least in part on the TCI state, and the UE 120 may not need to reconfigure antennas or antenna weighting configurations. In some examples, the set of activated TCI states (for example, activated PDSCH TCI states and activated CORESET TCI states) for the UE 120 may be configured by a configuration message, such as a radio resource control (RRC) message.

Similarly, for uplink communications, the UE 120 may transmit in the direction of the base station 110 using a directional UE transmit beam, and the base station 110 may receive the transmission using a directional BS receive beam. Each UE transmit beam may have an associated beam ID, beam direction, or beam symbols, among other examples. The UE 120 may transmit uplink communications via one or more UE transmit beams 415.

Some networks may use different beam indication types for indicating one or more beams to use for communication via a set of channels. Beam indication types may include a beam indication that indicates to use a common beam for multiple channels and/or resources for reference signals, and/or beam indication types that include a single beam indication that indicates to use a beam for a single channel or a resource for reference signals.

In a unified TCI framework, a beam indication type 1 may indicate a joint uplink/downlink TCI state to indicate a common beam for at least one downlink channel and/or resource for downlink reference signals and for at least one uplink channel or resource for uplink reference signals. A beam indication type 2 may indicate a separate downlink common TCI state to indicate a common beam for at least two downlink channels or resources for downlink reference signals. A beam indication type 3 may indicate a separate uplink common TCI state to indicate a common beam for at least two uplink channels or resources for uplink reference signals. A beam indication type 4 may indicate a single TCI state to indicate a single beam for a single downlink channel or resource for downlink reference signals. A beam indication type 5 may indicate a single TCI state to indicate a single beam for a single uplink channel or resource for uplink reference signals. A beam indication type 6 may indicate a single uplink spatial relation to indicate a single beam for a single uplink channel or resource for uplink reference signals. TCI states, such as the TCI states described above, may be updated using DCI or medium access control (MAC) control element (CE) (MAC-CE) signaling.

Under the unified TCI state framework, different options may be possible for signaling power control configuration. For example, in a first option, a base station may signal a power control configuration on a per uplink channel/per reference signal object basis (e.g., regardless of which TCI state is applied to the uplink channel or reference signal object). In this case, signaled power control parameters may correspond to the uplink channel/reference signal object and may be invariant to the applied TCI state. In a second option, the base station may signal a power control configuration on a per TCI state basis (e.g., regardless of to which uplink channel or reference signal object the TCI state applies). In this case, signaled power control parameters may correspond to the applied TCI state and may be invariant to a type of uplink channel or reference signal object to which the TCI state is applied. In a third option, the base station may signal a power control configuration on a per uplink channel/reference signal object and per TCI state basis. In this case, the signaled power control parameters depend on both the applied TCI state and the uplink channel/reference signal object. The options for power control configuration may be non-exclusive, such that, for example, the first option and the third option may be deployed.

The base station 110 may receive uplink transmissions via one or more BS receive beams 420. The base station 110 may identify a particular UE transmit beam 415, shown as UE transmit beam 415-A, and a particular BS receive beam 420, shown as BS receive beam 420-A, that provide relatively favorable performance (for example, that have a best channel quality of the different measured combinations of UE transmit beams 415 and BS receive beams 420). In some examples, the base station 110 may transmit an indication of which UE transmit beam 415 is identified by the base station 110 as a preferred UE transmit beam, which the base station 110 may select for transmissions from the UE 120. The UE 120 and the base station 110 may thus attain and maintain a BPL for uplink communications (for example, a combination of the UE transmit beam 415-A and the BS receive beam 420-A), which may be further refined and maintained in accordance with one or more established beam refinement procedures. An uplink beam, such as a UE transmit beam 415 or a BS receive beam 420, may be associated with a spatial relation. A spatial relation may indicate a directionality or a characteristic of the uplink beam, similar to one or more QCL properties, as described above.

As indicated above, FIG. 4 is provided as an example. Other examples may differ from what is described with respect to FIG. 4.

As described above, a UE may determine an uplink power based at least in part on a pathloss estimation. For example, the UE may use information identifying a transmit power for a PL-RS and a measurement of a received power of the reference signal to identify a path loss for a path between the UE and a base station. Examples of pathloss reference signals that the UE and the base station may use include an SSB and a CSI-RS. Using the pathloss estimation and a set of power control parameters, the UE may determine a transmit power with which to transmit without exceeding a configured maximum transmit power. Examples of power control parameters include a PO parameter, an alpha parameter, or a closed loop index parameter, among other examples.

A base station may indicate a beamforming channel and associated beam using a TCI state or spatial relationship. Different beamforming channels may have different path losses, which may result in the UE using different PL-RSs for different TCI states. However, a maximum quantity of PL-RSs with which the UE may be configured is less than a maximum quantity of TCI states or spatial relationships. For example, for a UE with a particular UE capability, the UE may be configured to support up to 64 spatial relationships and 64 candidate beams, but may be configured with only up to 4 PL-RSs. Accordingly, not all of the uplink beams may have an associated PL-RS, which may result in a misalignment between a spatial beam (e.g., the beam that a TCI state indicates the UE is to use for uplink transmission) and a PL-RS beam (e.g., the beam for which the UE has a configured PL-RS). When the UE is configured with a different spatial beam from the PL-RS beams that the UE can use, such a misalignment may be termed a “a beam misalignment state.”

As described above, different options for power control configuration may include configuring power control parameters per uplink channel/reference signal object, per TCI state, or both per uplink channel/reference signal object and per TCI state. Accordingly, a UE may have a static power control configuration with a static set of power control parameters that may be signaled. However, different channels, traffic types, or priorities may have different conditions with respect to path loss and associated power control. Moreover, beam misalignment may result in issues with measuring path loss and associated power control that some UEs may lack a capability for resolving. Incorrect power control as a result of a static power control configuration or a beam misalignment that the UE is not capable of handling may result in incorrect transmit power determinations and poor communication performance.

Some aspects described herein enable power control configuration. For example, a UE may receive signaling identifying a plurality of power control configurations with each power control configuration including one or more power control parameters and corresponding to a channel type, a traffic type, and/or a traffic priority. In this case, the UE may select a power control configuration and associated power control parameters based at least in part on a channel type, traffic type, and/or traffic priority of uplink traffic that the UE is to transmit. The traffic type, and/or traffic priority of uplink traffic may be indicated to UE in the same signaling that schedules the uplink traffic. Additionally, or alternatively, a UE may optionally report a capability for handling a beam misalignment state, and a base station may configure a PL-RS for the UE in accordance with a UE report of the capability for handling the beam misalignment state and/or a rule for handling when the UE does not transmit a UE report of the capability for handling the beam misalignment state. In this way, the base station and the UE may ensure an accurate transmit power determination and power control, thereby improving communication performance relative to other techniques for power control.

FIG. 5 is a diagram illustrating an example 500 associated with power control parameter configuration, in accordance with the resent disclosure. As shown in FIG. 5, example 500 includes communication between a base station 110 and a UE 120. In some aspects, base station 110 and UE 120 may be included in a wireless network, such as wireless network 100. Base station 110 and UE 120 may communicate via a wireless access link, which may include an uplink and a downlink.

As further shown in FIG. 5, and by reference number 505, UE 120 may receive signaling identifying a plurality of power control configurations. For example, base station 110 may transmit the signaling to UE 120 to identify the plurality of power control configurations that UE 120 can use to determine a transmit power for uplink traffic. In some aspects, UE 120 may receive information identifying a TCI state and/or a PL-RS in connection with receiving the information identifying the plurality of power control configurations. For example, UE 120 may receive a plurality of communications to identify the plurality of power control configurations, to identify the TCI state, and to receive and measure the PL-RS. Additionally, or alternatively, UE 120 may receive information identifying the plurality of power control configurations and the TCI state in a single communication.

In some aspects, UE 120 may receive signaling configuring the plurality of power control configurations using a particular signaling path, such as via RRC signaling, MAC-CE signaling, or DCI signaling (e.g., which may convey information identifying a physical priority of a scheduled uplink channel). In some aspects, UE 120 may transmit a UE capability indicator to identify a UE capability associated with power control configuration. For example, UE 120 may indicate a UE capability, and base station 110 may configure a plurality of power control parameters (e.g., on a per channel or per channel/TCI state basis) for UE 120 based at least in part on the UE capability.

In some aspects, UE 120 may receive information identifying power control configurations corresponding to different types of uplink channels for transmitting uplink traffic. For example, UE 120 may receive information identifying power control configurations corresponding to PRACH communications, PUCCH communications, PUSCH communications, or SRS communications, among other examples. Additionally, or alternatively, UE 120 may receive information identifying power control configurations for different types of uplink traffic associated with different services. For example, UE 120 may receive information identifying power control configurations to use for enhanced mobile broadband (eMBB) traffic or ultra-reliable low-latency communication (URLLC) traffic, among other examples. Additionally, or alternatively, UE 120 may receive information identifying power control configurations for different priorities of traffic. For example, UE 120 may receive information identifying different power control configurations for high priority traffic and low priority traffic (e.g., or any other prioritization of traffic).

In some aspects, UE 120 may receive a power control configuration with a set of power control parameters configured for a particular TCI state. For example, when power control parameters are to be configured per TCI state, per channel, each TCI state may be associated with a plurality of power control parameter set lists per channel, with each power control parameter set list including a plurality of different power control parameter sets for a plurality of different traffic types or priorities. In this case, based at least in part on an indicated TCI state, an indicated channel, and/or an indicated traffic type or priority, UE 120 may identify a particular set of power control parameters to use for transmit power determination. In some aspects, UE 120 may receive, from base station 110, an RRC information element (IE) of a TCI state or associated with a TCI state identifier and linked to a TCI state. The RRC IE may include information identifying the plurality of power control parameter set lists.

In some aspects, when power control parameters are to be configured per uplink channel/reference signal object (“per channel object”), UE 120 may receive information identifying different parameter sets for each channel type with each parameter set corresponding to a traffic type or priority that can be transmitted within the corresponding channel type. Additionally, or alternatively, UE 120 may receive information identifying different parameter sets for each resource set, with each parameter set corresponding to a traffic type or priority that can be transmitted within the corresponding resource set. For example, each SRS resource set or PUCCH resource set may be configured with different power control parameter sets. Additionally, or alternatively, UE 120 may receive information identifying different parameter sets for each transmission scheme (e.g., for PUSCH communications, parameter sets for codebook-based transmission or non-codebook based transmission).

As further shown in FIG. 5, and by reference number 510, UE 120 may determine a transmit power for uplink traffic. For example, UE 120 may determine a pathloss estimation and, using the pathloss estimation and a set of power control parameters of a selected power control configuration, UE 120 may determine the transmit power for the uplink traffic. In some aspects, UE 120 may identify an uplink channel, an uplink traffic type, an uplink priority, or a TCI state associated with the uplink traffic to determine the transmit power. For example, UE 120 may determine that the uplink traffic is associated with a particular channel and a particular traffic type and may select a power control configuration, of a plurality of power control configurations for a plurality of different channel types, associated with the particular channel and may select a set of power control parameters of a list of sets of power control parameters for the power control configuration. In this case, UE 120 may use the selected set of power control parameters to determine the uplink transmit power.

As further shown in FIG. 5, and by reference number 515, UE 120 may transmit in accordance with the selected power control configuration. For example, based at least in part on determining a transmit power using the selected power control configuration, UE 120 may transmit on an uplink using the determined transmit power.

As indicated above, FIG. 5 is provided as an example. Other examples may differ from what is described with respect to FIG. 5.

FIG. 6 is a diagram illustrating an example 600 associated with PL-RS configuration, in accordance with the present disclosure. As shown in FIG. 6, example 600 includes communication between a base station 110 and a UE 120. In some aspects, base station 110 and UE 120 may be included in a wireless network, such as wireless network 100. Base station 110 and UE 120 may communicate via a wireless access link, which may include an uplink and a downlink.

As further shown in FIG. 6, and by reference number 605, UE 120 may transmit a report of a UE capability relating to a beam misalignment state. For example, UE 120 may report support for beam misalignment, in which case, base station 110 may configure PL-RSs and allow for misalignment between the PL-RSs and beams associated with indicated TCI states. Additionally, or alternatively, UE 120 may report that UE 120 does not support beam misalignment. In this case, base station 110 may configure PL-RSs to avoid beam misalignment with an indicated TCI state. Additionally, or alternatively, UE 120 may forgo reporting a UE capability. In this case, base station 110 may follow a default rule for evaluating whether UE 120 supports beam misalignment (e.g., base station 110 may determine that, by default, UE 120 supports beam misalignment).

As described above, beam misalignment state may occur when an uplink spatial beam is different from the PL-RS beam, resulting in a beam misalignment between the PL-RS and an uplink spatial filter for the uplink spatial beam. In contrast, a beam alignment may occur when the PL-RS is the same beam as a spatial relation RS (e.g., a source RS for quasi-co-location (QCL) type-D) in an uplink or joint TCI state. Additionally, or alternatively, beam alignment may occur when the spatial relation RS is a direct or indirect QCL source of a PL-RS, or when the PL-RS is a direct or indirect QCL source of the spatial relation RS. Additionally, or alternatively, beam alignment may occur when the PL-RS and the spatial relation RS share a common QCL source (e.g., a common SSB). In some aspects, base station 110 may indicate a QCL relationship in a pre-configuration message. For example, base station 110 may indicate two RSs (e.g., two SSBs of the same index on two component carriers (CCs)) that are quasi-co-located and subject to the same TCI updates. In some aspects, base station 110 may not indicate a PL-RS for each TCI state. For example, base station 110 may indicate a PL-RS for a first set of TCI states and forgo indicating a PL-RS for a second set of TCI states, in this case, base station 110 and UE 120 may apply a default PL-RS to a TCI state (e.g., a PL-RS from a PL-RS list with a lowest index may be applied as a default PL-RS).

As further shown in FIG. 6, and by reference number 610, UE 120 and base station 110 may communicate to configure PL-RSs and identify a PL-RS for UE 120 to use for transmit power determination. For example, when UE 120 supports beam misalignment, base station 110 may configure PL-RSs and UE 120 may identify a default PL-RS from a configured PL-RS list when a PL-RS is not specified for a TCI state, as described above. In contrast, when UE 120 does not support beam misalignment and a TCI state is not configured with a PL-RS, UE 120 may identify a PL-RS based at least in part on a source RS of the TCI state. For example, UE 120 may use the source RS or the SSB source of the TCI state to identify the PL-RS.

As further shown in FIG. 6, and by reference number 615, based at least in part on identifying the PL-RS, UE 120 may communicate with base station 110. For example, UE 120 may receive the PL-RS, estimate a pathloss, determine a transmit power, and transmit uplink traffic based at least in part on identifying the PL-RS.

As indicated above, FIG. 6 is provided as an example. Other examples may differ from what is described with respect to FIG. 6.
