Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that the UE has received, from a network, a sufficient quantity of protocol data units (PDUs) to decode a frame. Accordingly, the UE may indicate, to the network, that the UE has decoded the frame. Similarly, the UE may determine that the network has received, from the UE, a sufficient quantity of PDUs to decode a frame. Accordingly, the UE may refrain from transmitting one or more additional PDUs associated with the frame. Additionally, or alternatively, the UE may receive, from the network, an indication to disable some feedback to the network. Accordingly, the UE may refrain from transmitting one or more feedback signals based at least in part on the indication. Numerous other aspects are described.
Description
FIELD OF THE DISCLOSURE

Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for traffic and feedback management based on frame decoding.


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.

DETAILED DESCRIPTION

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 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 determine that the UE has received (e.g., from the base station 110) a sufficient quantity of protocol data units (PDUs) to decode a frame and indicate (e.g., to the base station 10) that the UE 120 has decoded the frame. Additionally, or alternatively, the communication manager 140 may determine that the base station 110 has received (e.g., from the UE 120) a sufficient quantity of PDUs to decode a frame and refrain from transmitting one or more additional PDUs associated with the frame. Additionally, or alternatively, the communication manager 140 may receive (e.g., from the base station 110) an indication to disable some feedback to the network and refrain from transmitting one or more feedback signals based at least in part on the indication. 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 determine that the UE 120 has received, from the base station, a sufficient quantity of PDUs to decode a frame and refrain from transmitting one or more additional PDUs associated with the frame. Additionally, or alternatively, the communication manager 150 may determine that the base station 110 has received (e.g., from the UE 120) a sufficient quantity of PDUs to decode a frame and indicate (e.g., to the UE 120) that the base station 110 has decoded the frame. Additionally, or alternatively, the communication manager 150 may transmit (e.g., to the UE 120) an indication to disable some feedback from the UE 120 and refrain from monitoring an uplink control channel with the UE 120 based at least in part on the indication. 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. 3-16).


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. 3-16).


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 traffic and feedback management based on frame decoding, 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 900 of FIG. 9, process 1000 of FIG. 10, process 1100 of FIG. 11, process 1200 of FIG. 12, process 1300 of FIG. 13, process 1400 of FIG. 14, 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 900 of FIG. 9, process 1000 of FIG. 10, process 1100 of FIG. 11, process 1200 of FIG. 12, process 1300 of FIG. 13, process 1400 of FIG. 14, 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, a UE (e.g., the UE 120 and/or apparatus 1500 of FIG. 15) may include means for determining that the UE has received, from a network, a sufficient quantity of PDUs to decode a frame; and/or means for indicating, to the network, that the UE has decoded the frame. Additionally, or alternatively, the UE may include means for determining that the network has received, from the UE, a sufficient quantity of PDUs to decode a frame; and/or means for refraining from transmitting one or more additional PDUs associated with the frame. Additionally, or alternatively, the UE may include means for receiving, from the network, an indication to disable some feedback to the network; and/or means for refraining from transmitting one or more feedback signals based at least in part on the indication. The means for the UE 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, a base station (e.g., the base station 110 and/or apparatus 1600 of FIG. 16) may include means for determining that a UE has received, from the base station, a sufficient quantity of PDUs to decode a frame; and/or means for refraining from transmitting one or more additional PDUs associated with the frame. Additionally, or alternatively, the base station may include means for determining that the base station has received, from the UE, a sufficient quantity of PDUs to decode a frame; and/or means for indicating, to the UE, that the base station has decoded the frame. Additionally, or alternatively, the base station may include means for transmitting, to the UE, an indication to disable some feedback from the UE; and/or means for refraining from monitoring an uplink control channel with the UE based at least in part on the indication. 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.


Using network coding allows for a UE and a base station to replace retransmission with error correction. For example, in network coding, an encoder (or transmitter), such as the base station on a downlink or the UE on an uplink, may encode data, such as a set of source packets or original packets, into a set of encoded packets using network coding. As used herein, “packet” may refer to a service data unit (SDU) that is encoded and decoded by a medium access control (MAC) layer, a radio link control (RLC) layer, or another higher layer, or may refer to a protocol data unit (PDU) that is encoded and decoded by a physical (PHY) layer or another lower layer. An encoded packet may be the same as a source packet, may be a redundancy version of a source packet, may include a combination of multiple source packets (e.g., a subset of the source packets), and/or may include a redundancy version of the combination. The number of encoded packets may be the same as or different than the number of source packets. In some aspects, the number of encoded packets may be unlimited (e.g., the encoder may generate any number of encoded packets), such as when using a rateless network coding scheme. For example, the encoder may encode K source packets (where K=3) into N encoded packets (where N=4). The encoder transmits the encoded packets to a decoder (or receiver), such as the base station on an uplink or the UE on a downlink. The decoder uses network coding to decode the encoded packets and recover the source packets. As used herein, network coding may be performed using any type of network coding scheme, such as fountain coding, linear network coding, random linear network coding, Luby transform (LT) network coding, and/or Raptor network coding. Thus, the decoder can obtain the source packets even when some transmissions fail, and using less overhead than packet data convergence protocol (PDCP) duplication. For example, PDCP duplication may duplicate all of the source packets, while the example network coding uses fewer packets.


Another option for error correction is to use forward error correction (FEC) such that the decoder can recover the source packets, even when a channel between the transmitter and receiver is noisy, using one or more error correction codes (ECCs) encoded with the packets. For example, FEC may use an erasure coding scheme, such as Reed-Solomon codes or other maximum distance separable (MDS) codes. For example, the encoder may apply a generator matrix (e.g., represented by A) to the source packets (e.g., represented by a, b, and c) to generate the encoded packets. In one example, the generator matrix may be of a form similar to

where α represents a coefficient, such that the encoded packets may be represented by a, b, c, a+b+c, and a+αb+α2c. Other erasure coding schemes may include applying different generator matrices to the source packets to generate different encoded packets. Similar to network coding, by using FEC, the decoder can obtain the source packets while using less overhead than PDCP duplication.


When using network coding or FEC, a receiver (such as a UE on a downlink or a base station on an uplink) may successfully decode a frame of data before receiving all of the encoded packets from the transmitter (such as the UE on an uplink or the base station on a downlink). Accordingly, the transmitter wastes power, processing resources, and network resources by transmitting additional encoded packets that are not necessary. Additionally, the receiver may waste power and processing resources by monitoring for, and receiving, the additional encoded packets that are not necessary.


Some techniques and apparatuses described herein enable a base station (e.g., base station 110) to refrain from transmitting one or more additional PDUs by determining that a UE (e.g., UE 120) has received a sufficient quantity of PDUs to decode a frame associated with the additional PDU(s). For example, the UE 120 may indicate, to the base station 110, that the UE 120 has successfully decoded the frame. Additionally, or alternatively, the base station 110 may determine that the UE 120 has received the sufficient quantity of PDUs (e.g., using feedback from the UE 120). As a result, the base station 110 conserves power, processing resources, and network resources by not transmitting the additional PDU(s). Additionally, the UE 120 may conserve power and processing resources by not monitoring for, and receiving, the additional PDU(s).


Similarly, some techniques and apparatuses described herein enable the UE 120 to refrain from transmitting one or more additional PDUs by determining that the base station 110 has received a sufficient quantity of PDUs to decode a frame associated with the additional PDU(s). For example, the base station 110 may indicate, to the UE 120, that the base station 110 has successfully decoded the frame. As a result, the UE 120 conserves power, processing resources, and network resources by not transmitting the additional PDU(s). Additionally, the base station 110 may conserve power and processing resources by not monitoring for, and receiving, the additional PDU(s).



FIG. 3 is a diagram illustrating an example 300 associated with downlink traffic management based on frame decoding, in accordance with the present disclosure. As shown in FIG. 3, a base station 110 and a UE 120 may communicate with one another.


As shown by reference number 305, the base station 110 may transmit, and the UE 120 may receive, one or more packets (e.g., one or more PDUs/SDUs) associated with a frame of data. For example, the base station 110 may receive the frame of data from an application (e.g., as described in connection with FIGS. 4A, 4B, 5A, and/or 5B) for transmission over-the-air (OTA) to the UE 120. Accordingly, the base station 110 may encode the frame as one or more packets.


The base station 110 may apply network coding or FEC such that the one or more packets are one or more encoded packets from which the UE 120 may decode the frame of data. Accordingly, as shown by reference number 310, the UE 120 may decode the data from the PDU(s)/SDU(s) received from the base station 110. The decoding may occur at an application (e.g., as described in connection with FIGS. 4A and/or 5A) or at an access stratum of the UE 120 (e.g., as described in connection with FIGS. 4B and/or 5B).


As shown by reference number 315, the UE 120 may transmit, and the base station 110 may receive, feedback associated with the frame. In some aspects, the feedback may include acknowledgement (ACK) and/or negative-acknowledgement (NACK) signals such that the base station 110 may determine that the UE 120 has received a sufficient quantity of PDUs (or SDUs) to decode the frame. The sufficient quantity may be indicated by the application that generated the frame (e.g., as described in connection with FIGS. 4A and/or 5A) and/or determined at an access stratum of the base station 110 (e.g., as described in connection with FIGS. 4B and/or 5B). Accordingly, the base station 110 may determine that the UE 120 has received the sufficient quantity of PDUs (or SDUs) by comparing a quantity of the feedback signals, from the UE 120, to the sufficient quantity to decode the frame.


In some aspects, the base station 110 may transmit, and the UE 120 may receive, a configuration message associated with conditional deactivation of feedback (e.g., as described in connection with FIG. 8). Accordingly, the base station 110 may determine that the UE 120 has received the sufficient quantity of PDUs (or SDUs) by determining that the base station 110 either did not receive an ACK signal from the UE 120 or stopped receiving ACK/NACK signals from the UE 120.


Additionally, or alternatively, the UE 120 may transmit, and the base station 110 may receive, an indication that the UE 120 has successfully decoded the frame. For example, the UE 120 may transmit uplink control information (UCI), a MAC control element (MAC-CE), and/or another signal indicating that the UE 120 has decoded the frame. Accordingly, the base station 110 may determine that the UE 120 has received the sufficient quantity of PDUs (or SDUs) based on the indication from the UE 120.


In some aspects, the UE 120 transmits the indication with a lower MCS than other transmissions to the base station 110. As a result, reliability of the indication is improved so that the base station 110 will receive the indication and refrain from continuing to transmit PDUs to the UE 120.


In any of the aspects described above, the sufficient quantity of PDUs may include one or more PDUs that account for one or more erroneous decodings associated with the feedback signals. For example, an ACK from the UE 120 may be dropped or erroneously encoded and/or decoded as a NACK. Similarly, a NACK from the UE 120 may be dropped or erroneously encoded and/or decoded as an ACK. Accordingly, the application that generated the frame may determine the sufficient quantity to account for erroneous decoding(s) or the access stratum of the base station 110 may increase a quantity output by the application to account for erroneous decoding(s). As an alternative, the access stratum of the base station 110 may determine the sufficient quantity to account for erroneous decoding(s).


Accordingly, as shown by reference number 320, the base station 110 may refrain from transmitting, to the UE 120, one or more additional PDUs associated with the frame. As a result, the base station 110 conserves power, processing resources, and network resources by not transmitting the additional PDU(s).


In some aspects, and as shown by reference number 325, the base station 110 may additionally transmit, and the UE 120 may receive, an instruction to enter a low-power mode. As used herein, “low-power mode” may refer to an idle mode or an inactive state (e.g., as defined in 3GPP specifications) or another mode in which the UE 120 conserves power by not monitoring for communications, or monitoring for fewer than usual communications, from the base station 110. For example, the base station 110 may transmit downlink control information (DCI), a MAC-CE, and/or another signal instructing the UE 120 to enter the low-power mode. As a result, the UE 120 conserves power and processing resources. The base station 110 may transmit the instruction based on determining that the UE 120 has received the sufficient quantity of PDUs (or SDUs). Additionally, in some aspects, the base station 110 may transmit the instruction based on determining that a buffer of downlink data, intended for the UE 120, at the base station 110 is empty. Accordingly, as shown by reference number 330, the UE 120 may enter the low-power mode rather than monitoring for additional scheduling information from the base station 110.


In some aspects, the base station 110 transmits the instruction with a lower MCS than the packet(s) from the base station 110. As a result, reliability of the instruction is improved so that the UE 120 will receive the instruction and conserve power and processing resources.


By using techniques as described in connection with FIG. 3, the base station 110 refrains from transmitting the one or more additional PDUs by determining that the UE 120 has received the sufficient quantity of PDUs to decode the frame associated with the additional PDU(s). As a result, the base station 110 conserves power, processing resources, and network resources by not transmitting the additional PDU(s). Additionally, the UE 120 may conserve power and processing resources by not monitoring for, and receiving, the additional PDU(s).


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



FIGS. 4A and 4B are diagrams illustrating examples 400 and 450, respectively, associated with interfaces for downlink traffic management based on frame decoding, in accordance with the present disclosure. As shown in FIG. 4A, example 400 includes an application 403 (e.g., software executing on a server 401) that generates data (e.g., a frame of data) intended for an application 409 executing on a UE 120. Accordingly, the application 403 may pass the frame to an access stratum 405 of a gNB 110 for transmission OTA to the UE 120. The access stratum 405 encodes the frame as one or more PDUs for transmission to the UE 120. In example 400, the application 403 applies FEC to the frame such that the gNB 110 may transmit the PDU(s) without retransmission.


Accordingly, an access stratum 407 of the UE 120 may receive the PDU(s) OTA and pass the same to the application 409 for decoding. Once the application 409 decodes the frame, the application 409 may indicate (e.g., via an application programming interface (API)) that the frame was decoded to the access stratum 407. Accordingly, as described in connection with FIG. 3, the access stratum 407 of the UE 120 may transmit an indication (e.g., UCI) that the frame was decoded to the access stratum 405 of the gNB 110. As a result, the gNB 110 may refrain from transmitting one or more additional PDUs, associated with the frame, to the UE 120 to conserve power, processing resources, and network resources.


As an alternative, in example 450, the access stratum 405 of the gNB 110 applies network coding to the PDUs such that the gNB 110 may transmit the PDU(s) without retransmission. Accordingly, an access stratum 407 of the UE 120 may receive the PDU(s) OTA and decode the PDU(s). Once the access stratum 407 decodes the frame, the access stratum 407 of the UE 120 may transmit an indication (e.g., UCI) that the frame was decoded to the access stratum 405 of the gNB 110, as described in connection with FIG. 3. As a result, the gNB 110 may refrain from transmitting one or more additional PDUs, associated with the frame, to the UE 120 to conserve power, processing resources, and network resources.


By using techniques as described in connection with FIGS. 4A and 4B, the access stratum 405 of the gNB 110 refrains from transmitting the one or more additional PDUs by determining the UE 120 has received the sufficient quantity of PDUs for the application 409 to decode the frame associated with the additional PDU(s). As a result, the gNB 110 conserves power, processing resources, and network resources by not transmitting the additional PDU(s). Additionally, the UE 120 may conserve power and processing resources by not monitoring for, and receiving, the additional PDU(s).


As indicated above, FIGS. 4A and 4B are provided as examples. Other examples may differ from what is described with respect to FIGS. 4A and 4B.



FIGS. 5A and 5B are diagrams illustrating examples 500 and 550, respectively, associated with interfaces for downlink traffic management based on frame decoding, in accordance with the present disclosure. As shown in FIG. 5A, example 500 includes an application 403 (e.g., software executing on a server 401) that generates data (e.g., a frame of data) intended for an application 409 executing on a UE 120. Accordingly, the application 403 may pass the frame to an access stratum 405 of a gNB 110 for transmission OTA to the UE 120. The access stratum 405 encodes the frame as one or more PDUs for transmission to the UE 120. In example 400, the application 403 applies FEC to the frame such that the gNB 110 may transmit the PDU(s) without retransmission. Accordingly, the application 403 may indicate (e.g., via an API or a gateway) a sufficient quantity of PDUs to decode the frame to the access stratum 405.


Accordingly, an access stratum 407 of the UE 120 may receive the PDU(s) OTA and pass the PDU(s) to the application 409 for decoding. Once the gNB 110 determines that the sufficient quantity of PDUs have been received by the UE 120, the gNB 110 may refrain from transmitting one or more additional PDUs, associated with the frame, as described in connection with FIG. 3. As a result, the gNB 110 conserves power, processing resources, and network resources.


As an alternative, in example 550, the access stratum 405 of the gNB 110 applies network coding to the PDUs such that the gNB 110 may transmit the PDU(s) without retransmission. Accordingly, the access stratum 405 may determine the sufficient quantity of PDUs to decode the frame. Once the gNB 110 determines that the sufficient quantity of PDUs have been received by the UE 120, the gNB 110 may refrain from transmitting one or more additional PDUs, associated with the frame, as described in connection with FIG. 3. As a result, the gNB 110 conserves power, processing resources, and network resources.


By using techniques as described in connection with FIGS. 5A and 5B, the access stratum 405 of the gNB 110 refrains from transmitting the one or more additional PDUs by determining the UE 120 has received the sufficient quantity of PDUs for the access stratum 407 of the UE 120 to decode the frame associated with the additional PDU(s). As a result, the gNB 110 conserves power, processing resources, and network resources by not transmitting the additional PDU(s). Additionally, the UE 120 may conserve power and processing resources by not monitoring for, and receiving, the additional PDU(s).


As indicated above, FIGS. 5A and 5B are provided as examples. Other examples may differ from what is described with respect to FIGS. 5A and 5B.



FIG. 6 is a diagram illustrating an example 600 associated with uplink traffic management based on frame decoding, in accordance with the present disclosure. As shown in FIG. 6, a base station 110 and a UE 120 may communicate with one another.


As shown by reference number 605, the UE 120 may transmit, and the base station 110 may receive, an indication of a sufficient quantity of PDUs (or SDUs) to decode a frame of data (e.g., as described in connection with reference number 610). For example, the UE 120 may transmit UCI, a MAC-CE, and/or another signal indicating the sufficient quantity. The sufficient quantity may be indicated by the application that generated the frame (e.g., as described in connection with FIG. 7A) and/or determined at an access stratum of the UE 120 (e.g., as described in connection with FIG. 7B). Accordingly, the base station 110 may determine when the base station 110 has received the sufficient quantity of PDUs (or SDUs) based on the indication from the UE 120.


In some aspects, the UE 120 transmits the indication with a lower MCS than other transmissions to the base station 110. As a result, reliability of the indication is improved so that the base station 110 will receive the indication and can determine when the base station 110 has received the sufficient quantity. Additionally, or alternatively, the UE 120 may transmit the indication more than once (e.g., with a first quantity of a plurality of packets, as described in connection with reference number 610) in order to increase reliability of the indication. As a result, the base station 110 will receive the indication and can determine when the base station 110 has received the sufficient quantity.


As shown by reference number 610, the UE 120 may transmit, and the base station 110 may receive, one or more packets (e.g., one or more PDUs/SDUs) associated with the frame of data. For example, the UE 120 may receive the frame of data from an application (e.g., as described in connection with FIGS. 7A and/or 7B) for transmission OTA to the base station 110. Accordingly, the UE 120 may encode the frame as one or more packets.


The UE 120 may apply network coding or FEC such that the one or more packets are one or more encoded packets from which the base station 110 may decode the frame of data. Accordingly, as shown by reference number 615, the base station 110 may decode the data from the PDU(s)/SDU(s) received from the UE 120. The decoding may occur at an application (e.g., as described in connection with FIG. 7A) or at an access stratum of the base station 110 (e.g., as described in connection with FIG. 7B).


As shown by reference number 620, the base station 110 may transmit, and the UE 120 may receive, an indication that the base station 110 has received the sufficient quantity of PDUs (or SDUs)) to decode the frame. In some aspects, the indication may include DCI, a MAC-CE, an RLC control PDU, a PDCP control PDU, and/or another signal such that the UE 120 may determine that the base station 110 has a received a sufficient quantity of PDUs (or SDUs) to decode the frame.


In some aspects, the base station 110 transmits the indication with a lower MCS than other transmissions to the UE 120. As a result, reliability of the indication is improved so that the UE 120 will receive the indication and can determine when the base station 110 has received the sufficient quantity.


Accordingly, as shown by reference number 625, the UE 120 may refrain from transmitting, to the base station 110, one or more additional PDUs associated with the frame. As a result, the UE 120 conserves power, processing resources, and network resources by not transmitting the additional PDU(s).


In some aspects, and as shown by reference number 630, the base station 110 may additionally transmit, and the UE 120 may receive, an instruction to enter a low-power mode. For example, the base station 110 may transmit DCI, a MAC-CE, and/or another signal instructing the UE 120 to enter the low-power mode. As a result, and as shown by reference number 635, the UE 120 enters the low-power mode to conserve power and processing resources. The base station 110 may transmit the instruction based on determining that the base station 110 has received the sufficient quantity of PDUs (or SDUs). Additionally, in some aspects, the base station 110 may transmit the instruction based on determining that a buffer of uplink data, intended for the base station 110, at the UE 120 is empty. For example, the base station 110 may use one or more buffer status reports (BSRs), received from the UE 120, to determine that the buffer of uplink data is empty.


By using techniques as described in connection with FIG. 6, the UE 120 refrains from transmitting the one or more additional PDUs by determining that the base station 110 has received the sufficient quantity of PDUs to decode the frame associated with the additional PDU(s). As a result, the UE 120 conserves power, processing resources, and network resources by not transmitting the additional PDU(s). Additionally, the base station 110 may conserve power and processing resources by not monitoring for, and receiving, the additional PDU(s).


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



FIGS. 7A and 7B are diagrams illustrating examples 700 and 750, respectively, associated with interfaces for uplink traffic management based on frame decoding, in accordance with the present disclosure. As shown in FIG. 7A, example 700 includes an application 703 on a UE 120 that generates data (e.g., a frame of data) intended for an application 709 (e.g., software executing on a server 701). Accordingly, the application 703 may pass the frame to an access stratum 705 of a UE 120 for transmission OTA to a gNB 110. The access stratum 705 encodes the frame as one or more PDUs for transmission to the gNB 110. In example 500, the application 703 applies FEC to the frame such that the UE 120 may transmit the PDU(s) without retransmission. Accordingly, the application 703 may indicate (e.g., via an API or a gateway) a sufficient quantity of SDUs to decode the frame to the access stratum 705.


Accordingly, an access stratum 707 of the gNB 110 may receive the PDU(s) OTA and pass the PDU(s) to the application 709 for decoding. The access stratum 705 of the UE 120 may additionally indicate the sufficient quantity to the gNB 110. Once the gNB 110 determines that the sufficient quantity of SDUs have been received by the gNB 110, the gNB 110 may transmit an indication (e.g., a MAC-CE, an RLC control PDU, and/or a PDCP control PDU) that the frame can be decoded to the UE 120, as described in connection with FIG. 6. As a result, the UE 120 may refrain from transmitting one or more additional PDUs, associated with the frame, to the gNB 110, to conserve power, processing resources, and network resources.


As an alternative, in example 750, the access stratum 705 of the UE 120 applies network coding to the PDUs such that the UE 120 may transmit the PDU(s) without retransmission. Accordingly, the access stratum 705 may determine the sufficient quantity of PDUs to decode the frame. The access stratum 705 of the UE 120 may additionally indicate the sufficient quantity to the gNB 110. Once the gNB 110 determines that the sufficient quantity of SDUs has been received by the gNB 110, the gNB 110 may transmit an indication (e.g., a MAC-CE, an RLC control PDU, and/or a PDCP control PDU) that the frame can be decoded to the UE 120, as described in connection with FIG. 6. As a result, the UE 120 may refrain from transmitting one or more additional PDUs, associated with the frame, to the gNB 110 to conserve power, processing resources, and network resources.


By using techniques as described in connection with FIGS. 7A and 7B, the access stratum 705 of the UE 120 refrains from transmitting the one or more additional PDUs by determining that the gNB 110 has received the sufficient quantity of PDUs to decode the frame associated with the additional PDU(s). As a result, the UE 120 conserves power, processing resources, and network resources by not transmitting the additional PDU(s). Additionally, the gNB 110 may conserve power and processing resources by not monitoring for, and receiving, the additional PDU(s).


As indicated above, FIGS. 7A and 7B are provided as examples. Other examples may differ from what is described with respect to FIGS. 7A and 7B.


When network coding or FEC is used, hybrid automatic repeat request (HARD) feedback may waste network resources, power, and processing resources because retransmissions are disabled in favor of the network coding or the FEC. Accordingly, some techniques and apparatuses described herein enable a base station (e.g., base station 110) to indicate that a UE (e.g., UE 120) should refrain from transmitting one or more feedback signals. As a result, the UE 120 conserves power, processing resources, and network resources by not transmitting the feedback signal(s). In some aspects, the UE 120 may enter a low-power state sooner than if the UE 120 had transmitted the feedback signal(s), which further conserves power and processing resources. Additionally, the base station 110 may conserve power and processing resources by not monitoring for, and receiving, the feedback signal(s).



FIG. 8 is a diagram illustrating an example 800 associated with feedback management based on frame decoding, in accordance with the present disclosure. As shown in FIG. 8, a base station 110 and a UE 120 may communicate with one another.


As shown by reference number 805, the base station 110 may transmit, and the UE 120 may receive, an indication to disable some feedback to the network. The indication may include an RRC message and/or DCI.


The indication may instruct the UE 120 to omit feedback unconditionally. Accordingly, the UE 120 may refrain from transmitting any feedback signals to the base station 110. In some aspects, the indication may further include an ackNack-Mask parameter and/or another parameter such that the UE 120 refrains from transmitting any feedback signals to the base station 110 outside an active discontinuous reception (DRX) time associated with the UE 120.


As an alternative, the indication may instruct the UE 120 to omit feedback conditionally. Accordingly, the UE 120 may refrain from transmitting feedback signals, associated with a frame of data, to the base station 110 after the UE 120 successfully decodes the frame. Additionally, or alternatively, the base station 110 may transmit, and the UE 120 may receive, the indication after the UE 120 indicates that the UE 120 successfully decoded the frame. Accordingly, the UE 120 may omit feedback dynamically when instructed by the base station 110.


As shown by reference number 810, the base station 110 may transmit, and the UE 120 may receive, one or more packets (e.g., one or more PDUs/SDUs) associated with a frame of data. For example, the base station 110 may receive the frame of data from an application (e.g., as described in connection with FIGS. 4A, 4B, 5A, and/or 5B) for transmission OTA to the UE 120. Accordingly, the base station 110 may encode the frame as one or more packets. The base station 110 may apply network coding or FEC such that the one or more packets are one or more encoded packets from which the UE 120 may decode the frame of data. The UE 120 may decode the data from the PDU(s)/SDU(s) at an application (e.g., as described in connection with FIGS. 4A and/or 5A) or at an access stratum of the UE 120 (e.g., as described in connection with FIGS. 4B and/or 5B).


In some aspects, and as shown by reference number 815, the UE 120 may transmit, and the base station 110 may receive, one or more feedback signals. In some aspects, the feedback may include ACK and/or NACK signals. For example, the indication described in connection with reference number 805 may have included a configuration message associated with conditional deactivation of feedback. Accordingly, the UE 120 may still transmit some feedback. As an alternative, the indication described in connection with reference number 805 may have included a configuration message associated with unconditional deactivation of feedback. Accordingly, the UE 120 may omit processes described in connection with reference number 815.


After the base station 110 transmits a final PDU associated with the frame, as shown by reference number 830, the UE 120 may refrain from transmitting one or more feedback signals to the base station 110, as shown by reference number 825. The UE 120 may refrain based on the indication from the base station 110. Additionally, in some aspects, the UE 120 may refrain based on determining that a downlink period associated with the frame has ended (e.g., by the base station 110 transmitting the final PDU). Accordingly, the base station 110 may refrain from monitoring an uplink control channel (e.g., a physical uplink control channel (PUCCH)) with the UE 120 in order to conserve power and processing resources.


In some aspects, and as shown by reference number 830, the base station 110 may transmit, and the UE 120 may receive, an instruction to enter a low-power mode. For example, the base station 110 may transmit DCI (e.g., including a new “Disable HARQ Feedback & Go To Sleep” parameter, as may be defined in 3GPP specifications and/or another standard, and/or including a “PDSCH-to-HARQ feedback timing indicator” that is associated with an RRC parameter like dl-DataToUL-ACK set to a new value like −1, as defined in 3GPP specifications and/or another standard), a MAC-CE, and/or another signal instructing the UE 120 to enter the low-power mode. As a result, the UE 120 conserves power and processing resources. The base station 110 may transmit the instruction based on determining that the UE 120 has received a sufficient quantity of PDUs (or SDUs), as described in connection with FIG. 3. Additionally, in some aspects, the base station 110 may transmit the instruction based on determining that a buffer of downlink data, intended for the UE 120, at the base station 110 is empty. Accordingly, as shown by reference number 830, the UE 120 may enter the low-power mode rather than monitoring for additional scheduling information from the base station 110.


As shown by reference number 835, the UE 120 may enter the low-power state. For example, the UE 120 may enter the low-power mode based at least in part on the instruction from the base station 110. Additionally, or alternatively, the base station 110 may set (e.g., via RRC signaling) a retransmission timer to zero (e.g., by setting a drx-RetransmissionTimerDL, as defined in 3GPP specifications and/or another standard, to a value of zero) and an inactivity timer to a low (e.g., less than a few microseconds (ms)) value (e.g., by setting a DRX_InactivityTimer, as defined in 3GPP specifications and/or another standard, to a value of zero).


By using techniques as described in connection with FIG. 8, the base station 110 indicates that the UE 120 should refrain from transmitting one or more feedback signals. As a result, the UE 120 conserves power, processing resources, and network resources by not transmitting the feedback signal(s). In some aspects, the UE 120 may enter a low-power state sooner than if the UE 120 had transmitted the feedback signal(s), which further conserves power and processing resources. Additionally, the base station 110 may conserve power and processing resources by not monitoring for, and receiving, the feedback signal(s).


As indicated above, FIG. 8 is provided as an example. Other examples may differ from what is described with respect to FIG. 8.



FIG. 9 is a diagram illustrating an example process 900 performed, for example, by a UE, in accordance with the present disclosure.

As shown in FIG. 9, in some aspects, process 900 may include determining that the UE has received, from a network (e.g., including base station 110 and/or apparatus 1600 of FIG. 16), a sufficient quantity of PDUs to decode a frame (block 910). For example, the UE (e.g., using communication manager 140 and/or determination component 1508, depicted in FIG. 15) may determine that the UE has received, from a network, a sufficient quantity of PDUs to decode a frame, as described herein.

In a fifth aspect, alone or in combination with one or more of the first through fourth aspects, process 900 further includes refraining from monitoring (e.g., using communication manager 140 and/or reception component 1502) for additional PDUs from the network based at least in part on indicating to the network that the UE has decoded the frame.

As shown in FIG. 11, in some aspects, process 1100 may include determining that a network (e.g., including base station 110 and/or apparatus 1600 of FIG. 16) has received, from the UE, a sufficient quantity of PDUs to decode a frame (block 1110). For example, the UE (e.g., using communication manager 140 and/or determination component 1508, depicted in FIG. 15) may determine that a network has received, from the UE, a sufficient quantity of PDUs to decode a frame, as described herein.


As further shown in FIG. 11, in some aspects, process 1100 may include refraining from transmitting one or more additional PDUs associated with the frame (block 1120).

FIG. 12 is a diagram illustrating an example process 1200 performed, for example, by a base station, in accordance with the present disclosure. Example process 1200 is an example where the base station (e.g., base station 110 and/or apparatus 1600 of FIG. 16) performs operations associated with traffic management based on frame decoding.


As shown in FIG. 12, in some aspects, process 1200 may include determining that the base station has received, from a UE (e.g., UE 120 and/or apparatus 1500 of FIG. 15), a sufficient quantity of PDUs to decode a frame (block 1210). For example, the base station (e.g., using communication manager 150 and/or determination component 1608, depicted in FIG. 16) may determine that the base station has received, from a UE, a sufficient quantity of PDUs to decode a frame, as described herein.

Although FIG. 12 shows example blocks of process 1200, in some aspects, process 1200 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in FIG. 12. Additionally, or alternatively, two or more of the blocks of process 1200 may be performed in parallel.



FIG. 13 is a diagram illustrating an example process 1300 performed, for example, by a UE, in accordance with the present disclosure. Example process 1300 is an example where the UE (e.g., UE 120 and/or apparatus 1500 of FIG. 15) performs operations associated with feedback management based on frame decoding.


As shown in FIG. 13, in some aspects, process 1300 may include receiving, from a network (e.g., including base station 110 and/or apparatus 1600 of FIG. 16), an indication to disable some feedback to the network (block 1310). For example, the UE (e.g., using communication manager 140 and/or reception component 1502, depicted in FIG. 15) may receive, from a network, an indication to disable some feedback to the network, as described herein.


As further shown in FIG. 13, in some aspects, process 1300 may include refraining from transmitting one or more feedback signals based at least in part on the indication (block 1320). For example, the UE (e.g., using communication manager 140 and/or transmission component 1504, depicted in FIG. 15) may refrain from transmitting one or more feedback signals based at least in part on the indication, as described herein.
