Techniques for feedback message payload size correction

Abstract

This disclosure provides methods, components, devices and systems for techniques for feedback message payload size correction. For example, techniques described herein may enable cyclic redundancy check (CRC) computation using a modified set of bits to differentiate between a CRC computed based on a relatively shorter hybrid automatic feedback request (HARQ) message and a CRC computed based on a relatively longer HARQ message. For example, a user equipment (UE) and a network entity may compute the CRC based on appending a quantity of ones to the payload prior to computing the CRC, by reversing an order of information bits of the payload prior to computing the CRC, or by using HARQ size-specific CRC computation function to compute the CRC such that a CRC function for a relatively larger HARQ message may be different from a CRC function for a relatively shorter HARQ message.

[0041] A communication system may include a radio access network (RAN) that supports wireless communication. Communication of a RAN may be performed in accordance with one or more radio access technologies (RATs), including 4G, 5G, or 6G, among others, including technologies not explicitly mentioned herein. A RAT may employ access technologies (such as multiplexing technologies) including code division multiple access (CDMA), time division multiple access (TDMA). frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), single-carrier FDMA (SC-FDMA), time division synchronous code division multiple access (TD-SCDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM), among others. A RAT may support one or more service types, including machine type communication (MTC), massive MTC (mMTC), Internet of Things (loT), narrowband loT (NB-IoT), reduced capability (RedCap), enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), or public safety, among others.

[0042] To support these and other target verticals, a communication system (such as a RAN) may be designed to implement one or more of a modularized functional infrastructure, a disaggregated and service-based network architecture, network function virtualization, network slicing, multi-access edge computing, spatial processing or multipath techniques, loT or RedCap device connectivity and management, industrial connectivity, licensed and unlicensed spectrum access, sidelink or other device-to-device (D2D) direct communication (such as vehicle-to-every thing (V2X)), frequencyAttorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO11spectrum expansion, overlapping spectrum use, small cell deployments, non -terrestrial network (NTN) deployments, device aggregation, advanced duplex communication (such as sub-band full-duplex (SBFD)), multiple-subscriber implementations, high-precision positioning, radio frequency (RF) sensing, network energy savings (NES), low-power signaling and radios, or artificial intelligence or machine learning (AI / ML), among other examples.

[0043] The foregoing and other technological improvements may support use cases such as voice calls, messaging, data transfer, streaming, wireless data centers, extended reality (XR) and metaverse applications, vehicle connectivity, holographic and mixed reality communication, autonomous and collaborative robots, sensing networks, gesture monitoring, human-brain interfacing, digital twin applications, asset management, and universal coverage using non-terrestrial or aerial platforms, among other examples. As the demand for connectivity continues to increase, further improvements may be implemented, and other RATs. including 6G and beyond, may be introduced to enable new applications and use cases. The systems, methods, and devices described herein may enable one or more of the foregoing technologies or new technologies or support one or more of the foregoing use cases or new use cases.

[0044] In some wireless communications systems, a user equipment (UE) may transmit a hybrid automatic repeat request (HARQ) feedback message (e.g., a HARQ-ACK message) indicating whether the UE received one or more messages (e.g., code blocks (CBs)) from a network entity. The UE may compute a parity value (e.g., a cyclic redundancy check (CRC)) based on inputting one or more bits of the HARQ feedback message into a function. The UE may encode the HARQ message using polar coding techniques in which the UE may append a quantity of frozen bits (e.g., zeroes) to the message prior to transmission.

[0045] In some examples, however, the UE may not receive or successfully decode a control message (e.g., a downlink control information (DCI) message) indicating a size of the HARQ feedback message. In such examples, the UE may transmit a HARQ message with a relatively smaller size than a size expected by the network entity, which may be associated with a same CRC as a relatively longer HARQ message including one or more zeros prior to a matching set of information bits. For example, a message with a payload of [al, a2, . . . aN] may result in a same CRC as a message with aAttorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO12payload of [0, 0, 0, al, a2, . . . aN], The network entity may accordingly interpret one or more of the frozen bits (e.g., zeroes) as information bits, which may result in the network entity incorrectly decoding the HARQ message.

[0046] Aspects of the subject matter described in this disclosure relate to techniques for CRC computation using a modified set of bits to differentiate between a CRC computed based on a relatively shorter HARQ message and a CRC computed based on a relatively longer HARQ message. For example, the UE and the network entity may compute the CRC based on appending a quantity of ones to the payload prior to computing the CRC. Additionally, or alternatively, the UE and the network entity may reverse an order of information bits of the pay load prior to computing the CRC.Additionally, or alternatively, the UE and the network entity may use HARQ sizespecific CRC computation function to compute the CRC such that a CRC function for a relatively larger HARQ message may be different from a CRC function for a relatively shorter HARQ message.

[0047] Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some examples, by enabling differentiation between CRCs computed using differently sized HARQ payloads, the described techniques can be used to improve coordination between device by enabling a network entity7to more accurately determine HARQ feedback from a UE. For example, by computing CRCs using a set of ones appended to the pay load, a reversed payload, or size-specific CRC computation functions, the network entity may determine whether a UE received a DCI indicating a HARQ size. The network entity7may accordingly retransmit one or more transmissions to the UE, which may result in improved coordination and improved reliability in the wireless communications system.

[0048] Figure 1 shows an example of a wireless communication system 100. The wireless communication system 100 includes a core network 150 and a RAN 120 that support communication with one or more devices, such as UEs 115. A RAN 120 may include one or more network entities 105 configured to support wireless communication with the UEs 115.

[0049] The wireless communication system 100 may support communication among network entities 105 and UEs 115 in accordance with a layered protocol stack. For example, in a user plane, communication at a bearer layer, a Packet Data Attorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO13Convergence Protocol (PDCP) layer, or Service Data Adaption Protocol (SDAP) layer may be Internet Protocol (IP)-based. A Radio Link Control (RLC) layer may perform packet segmentation and reassembly to communicate via logical channels. A Medium Access Control (MAC) layer may perform priority handling and multiplexing of logical channels into transport channels. A MAC layer also may implement error detection techniques, error correction techniques, or retransmissions. In a control plane, a Radio Resource Control (RRC) layer may provide establishment, configuration, and maintenance of an RRC connection between UEs 115 and a network entity 105 or a core network 150, supporting radio bearers for user plane data. A Physical (PHY) layer may map transport channels to physical channels.

[0050] A core network 150 may support user authentication, access authorization, tracking, IP connectivity, and other access, routing, or mobility functions (such as via network entities 105). A core network 150 may be a 5G core (5GC) or 6G core (6GC), and may include at least one control plane entity that manages access and mobility and at least one user plane entity that routes packets or interconnects to external networks (such as a serving gateway (S-GW), a Packet Data Network (PDN) gateway (P-GW), a user plane function (UPF)).

[0051] A network entity 105 may support wireless communication in accordance with one or more coverage areas 110, and may be referred to as a network element, a network node, a RAN node, or network equipment, among other nomenclature. One or more of the network entities 105 may include or may be referred to as a base station. Depending on its capabilities, a base station may be referred to as aNodeB, an eNodeB (eNB), a next-generation NodeB or giga-NodeB (either of which may be referred to as a gNB), a 5G NB, a 6G NB, a next-generation eNB (ng-eNB), a Home NodeB. a Home eNodeB, or other suitable terminology. The wireless communication system 100 may include a heterogeneous network in which different types of network entities 105 support communication for one or more coverage areas 110 using the same or different RATs.

[0052] In some examples, a network entity 105 may be implemented in an aggregated (such as monolithic, standalone) architecture, which may utilize a protocol stack that is physically or logically integrated within one network entity 105 (such as a single physical RAN node). In some other examples, a network entity’ 105 may beAttorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO14implemented in a disaggregated architecture, which may utilize a protocol stack that is physically or logically distributed among multiple network entities 105, including in an integrated access and backhaul (IAB) network, an open RAN (O-RAN), or a virtualized RAN (vRAN). In a disaggregated architecture, a network entity 105 may include or be referred to as one or more of a central unit (CU) (such as CU 160), a distributed unit (DU) (such as DU 165), a radio unit (RU) (such as RU 170), or a combination thereof. The wireless communication system 100 may also implement a service-based architecture that provides a modular framework in which control plane functionality and common data repositories may be delivered through a set of interconnected network functions (NFs) that may access services of other NFs.

[0053] UEs 115 may be located in a coverage area 110 of one or more network entities 105, and may include or be referred to as an access terminal, a mobile station, a client device, or a subscriber unit. A UE 115 may be, include, or be coupled with a cellular phone, a wireless modem, a tablet device, a laptop computer, a wireless local loop (WLL) station, a camera, a medical or biometric device, a wearable device, a gaming device, an entertainment device, an XR device, a vehicular component or sensor, a smart meter or sensor, industrial manufacturing equipment, a Global Positioning System (GPS) or other positioning device, a robot or other device implementing artificial intelligence, a UE function of a network node, or any other wireless communication device or function that may communicate using a wireless medium.

[0054] The wireless communication system 100 may support various types of communication links among devices. For example, wireless communication between a network entity 105 and a UE 115 may be supported using one or more of a communication link 125 (such as a Uu interface), which may include downlink communication from a network entity 105 to aUE 115, uplink communication from a UE 115 to a network entity7105, or both. Direct wireless communication between UEs 115 may be supported using a communication link 135 (such as a device-to-device (D2D) communication link, a sidelink, a PC5 interface).

[0055] Communication between a network entity 105 and a core network 150 may be supported using a backhaul link 132 (such as an SI, N2, N3. NG, or other interface). In some implementations, communication between network entities 105 may beAttorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO15supported using a backhaul link 132 (such as an X2, Xn, or other interface) either directly (such as directly between network entities 105) or indirectly (such as via a core network 150). In some implementations (such as in a disaggregated architecture), communication between a CU 160 and a DU 165 may be supported using a midhaul link 162, and communication between a DU 165 and an RU may be supported using a fronthaul link 168. A backhaul link 132, a midhaul link 162, a fronthaul link 168, or any combination thereof may be or include one or more wired links (such as an electrical link, an optical fiber link) or one or more wireless links (such as a radio link, a wireless optical link), among other examples or combinations thereof. Wireless backhaul, midhaul, or fronthaul may be implemented via one or more I AB nodes 104, which may act as a relay using resources of an IAB donor network entity 105 (such as via a wireless link 130).

[0056] The wireless communication system 100 may include one or more of a relay 172 that may steer or reflect signals transmitted by other entities, which may support any of the described communication links. A relay 172 may include active elements or passive elements, and may be in the form of a reconfigurable intelligent surface (RIS). An RIS may include tunable reflecting antenna arrays or metasurfaces, which may be used to enhance coverage or efficiency in multipath environments.

[0057] Network entities 105 and UEs 115 each may include one or multiple antennas. Multiple antennas of such devices may be used to employ techniques such as transmit diversity, receive diversity, M1M0 communication, or beamforming, and may be organized or structured as one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, among other examples. As used herein, the term “antenna” may refer to one or more antennas, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays. The term “antenna panel” may refer to a group of antennas (such as antenna elements) arranged in an array or panel, which may facilitate beamforming by manipulating parameters associated with the group of antennas. In some implementations, an antenna panel may support RF beamforming for a signal transmitted or received via an antenna port. The term “antenna module” may refer to circuitry including one or more antennas as well as one or more otherAttorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO16components (such as filters, amplifiers, processors, beamformers) associated with integrating the antenna module into a device such as a network entity 105 or a UE 115.

[0058] Beamforming, such as directional transmission or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (such as at a network entity 105, at a UE 115) to shape or steer a beam 175 (such as an antenna beam, a transmit beam, a receive beam) along a spatial path (such as along a direction), which may include one or more paths between a transmitting device and a receiving device. Beamforming may be achieved by combining signals communicated via multiple antenna elements of an antenna array such that signals propagating along some orientations (such as relative to the antenna array) experience constructive interference while others may experience destructive interference.Adjustments of signals communicated via the antenna elements may include a transmitting device or a receiving device applying phase offsets, amplitude offsets, or both to signals carried via (such as transmitted by. received by) antenna elements of the device, which may be defined by a beamforming weight set associated with a particular orientation (such as relative to the antenna array of the device).

[0059] Communication resources of the wireless communication system 100 (such as of a RAN 120) may refer to a resource in the frequency domain (such as a frequency resource, an RF resource), a resource in the time domain (such as a time resource), a resource in the spatial domain (such as a spatial resource, a spatial layer), or a combination thereof. The wireless communication system 100 may leverage orthogonality' of such resources to convey different communications to or from different devices (such as for a communication link 125, for a communication link 135, for unicast communication, for multicast communication, for broadcast communication).

[0060] A frequency resource may refer to a frequency or range of frequencies (such as a bandwidth, a frequency channel) of a frequency band implemented for wireless communication. For example, a frequency resource may refer to a resource of a lower frequency band (such as Frequency Range 1 (FR1), between 425 MHz and 7.125 GHz), a mid-band (such as Frequency Range 3 (FR3), between 7.125 GHz and 24.25 GHz), or an upper frequency band (such as Frequency Range 2 (FR2), between 24.25 GHz and 71 GHz). Communication in the upper frequency band may be referred to as millimeter wave (mmW) communication, and communication above an upper frequency bandAttorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO17(such as between mmW and THz frequencies, between 100 GHz and 1 THz) may be referred to as sub-Terahertz (sub-THz) communication.

[0061] A frequency resource may refer to a ’‘carrier” (such as a frequency channel), or portion thereof, and a carrier bandwidth may be referred to as a “system bandwidth.” A carrier may be subdivided in the frequency domain, including into subcarriers, bandwidth parts (BWPs), or both. For example, a resource block (RB), such as a physical resource block (PRB), may be defined in accordance with a set of subcarriers (such as twelve consecutive subcarriers in the frequency domain), and a BWP may be configured in accordance with a set of RBs (such as a set of contiguous RBs).

[0062] A frequency resource may be configured to carry7either downlink communication or uplink communication (such as in a frequency division duplexing (FDD) configuration), or may be configured to carry both downlink and uplink communication (such as in a time division duplexing (TDD) configuration, in a subband full duplex (SBFD) configuration). One or more numerologies for a carrier may be supported, each associated with a subcarrier spacing (SCS) and a cyclic prefix (CP). Supported numerologies may vary by frequency range (such as FR1, FR2, FR3), and a carrier may be divided into portions (such as BWPs) having the same or different numerologies. BWPs may be configured as uplink BWPs or downlink BWPs (such as by a network entity 105), including in response to network conditions (such as to allocate uplink and downlink BWPs in response to traffic conditions), device capability7(such as allocating BWPs with a greater quantity of RBs to UEs 115 with relatively higher capabilities), or both. A UE 115 may be configured with a set of multiple BWPs (such as a set of uplink BWPs, a set of downlink BWPs, or both), and a single BWP of a set (such as an active UL BWP, an active DL BWP, or both) may be active at a given time, such that communication of a UE 115 is supported by active BWP(s).

[0063] A time resource may refer to a duration of a frame (such as a radio frame, a frame structure), or portion thereof. For example, a frame may span a duration of 10 ms, and each frame may be identified by7a system frame number (SFN). A frame may be subdivided in the time domain, including into subframes, slots, mini-slots, or a combination thereof. Slots or mini-slots may each include a respective quantity of symbols (such as symbol durations, symbol periods, OFDM symbols), which may be aAttorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO18function of a configured CP. A duration of a symbol is a function of the SCS or frequency band of operation.

[0064] A spatial resource may refer to an antenna, an antenna direction, an antenna port, a signal direction (such as a beamforming direction), or other resource that supports spatial orthogonality. A device (such as a network entity 105, a UE 115) may perform communications of a given frequency resource and time resource with a single spatial resource (such as communication without regard to spatial orthogonality).Additionally, or alternatively, a device may implement multiple spatial resources to support multiple signal streams using resources that are overlapping in the time and frequency domains (such as to support MIMO techniques).

[0065] Signals of the wireless communication system 100 (such as of a RAN 120) may be communicated using one or more resource elements (REs), and an RE may refer to a resource that corresponds to one subcarrier in the frequency domain and one symbol in the time domain. An RE may be used to convey a modulation symbol corresponding to one or more bits of information (such as of a physical channel, of a reference signal) in accordance with a modulation scheme. For example, a quadrature phase shift keying (QPSK) or quadrature amplitude modulation (QAM) technique may be implemented to communicate one or more bits that are distinguished in accordance with phase components, amplitude components, or both of a signal conveyed using a RE. A quantity of bits carried by an RE may depend on an order of the modulation scheme, and a relatively higher order may correspond to a relatively higher rate of communication. A device may support communication of REs using multiple subcarriers concurrently by implementing multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM), among others.

[0066] Physical channels may carry information using modulation symbols conveyed by corresponding REs. Physical shared channels (such as for communicating user data) may include a physical downlink shared channel (PDSCH) for communicating user data in a downlink direction and a physical uplink shared channel (PUSCH) for communicating user data in an uplink direction. Physical control channels (such as for managing communication via physical channels) may include a physical downlink control channel (PDCCH) for communicating downlink control informationAttorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO19(DCI) and a physical uplink control channel (PUCCH) for communicating uplink control information (UCI). A network entity 105 may indicate (such as schedule, allocate) communication resources for a UE 115 using DCI, including indicating downlink resources of a PDSCH (such as in accordance with a downlink grant), uplink resources of a PUSCH (such as in accordance with an uplink grant), or a combination thereof. A control region (such as a control resource set (CORESET)) for a physical control channel may be configured in accordance with a pattern of REs in the time and frequency domains, and one or more control regions may be configured for a set of UEs. A UE 115 may monitor control regions for control information according to one or more search space sets, which may include a common search space set (such as for sending control information to one or more UEs 115), UE-specific search space sets (such as for sending control information to a UE 115), or a combination thereof. A physical broadcast channel (PBCH) may be used to broadcast parameters to UEs 115 to synchronize with a network entity 105 and establish communications (such as to establish a communication link 125).

[0067] Reference signals may be communicated to establish reference characteristics (such as a frequency reference, a temporal reference, a spatial reference, a signal quality reference) between devices of a RAN 120, which may support communication using physical channels. Reference signals communicated between network entities 105 and UEs 115 may include synchronization signals (such as a primary synchronization signal (PSS), a secondary synchronization signal (SSS)) that support temporal synchronization, channel state information-reference signals (CSI-RSs) that support evaluating downlink channel characteristics, sounding reference signals (SRSs) that support evaluating uplink channel characteristics, demodulation reference signals (DMRSs) that support demodulation, or phase tracking reference signals (PTRSs) for evaluating oscillator characteristics, among others. Network entities 105 and UEs 115 may receive and measure transmitted reference signals to support one or more of these and other functions.

[0068] To transmit information, a transmitting device (e.g., a UE 115, a network entity' 105) may encode a set of information bits via an encoder. An encoder may have a finite input bus width or input bits of a single input vector may become available at different times. For example, an input vector may include information bits, parity bits,Attorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO20check bits, etc., where some or all information bits may be generated by or received from different sources. Parity bits may be used in parity' check (PC), or cyclic redundancy check (CRC) techniques. Construction of an input vector may depend on information bit location / distribution amongst the channel instances of the encoder. The input vector may be, for example, a physical channel message (e.g., control channel message) or a data or shared channel message (e.g., a data packet). The encoder may generate different redundancy versions (RVs), which may include different combinations of encoded bits (e.g., systematic bits, redundancy bits).

[0069] The UEs 115 and the network entities 105 may support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) feedback is one technique for increasing the likelihood that data is received correctly via a communication link (e.g., a communication link 125, a D2D communication link 135). HARQ may include a combination of error detection (e.g.. using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)), and may support retransmissions of different RVs. HARQ may improve throughput at the MAC layer in poor radio conditions (e.g., low signal-to-noise conditions). In some examples, a device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific slot for data received via a previous symbol in the slot. In some other examples, the device may provide HARQ feedback in a subsequent slot, or according to some other time interval.

[0070] System performance of transmission of information bits in low-latency environments may be determined by factors such as overhead, coding gain, transmission pipelining, and decoding delay. Some processing techniques may emphasize improving transmission pipelining and decoding delay at the expense of higher overhead and lower coding gain. Generally, use of a larger code length (e.g., larger codeword) provides higher coding gain. However, a larger code length result in a larger decoding delay and overall system latency. In contrast, smaller code length reduces latency or decoding delay, but may result in an increase in overhead or lower coding gain.

[0071] Devices of the wireless communication system 100 may be configured to support one or more aspects of the described techniques for feedback message pay load size correction. For example, a UE 115 may include a processing system 140, and aAttorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO21network entity 105 may include a processing system 145, each of which may be configured to cause the respective device to perform (such as being configured as means for performing) one or more of the described operations. By configuring a processing system 140, a processing system 145, or a combination thereof in accordance with the described techniques, the communication system 100 (such as the RAN 120) may enable the UE 115 and the network entity 105 to differentiate between a CRC computed based on a relatively shorter HARQ message and a CRC computed based on a relatively longer HARQ message.

[0072] For example, the UE 115 and the network entity 105 may compute the CRC based on appending a quantity of ones to the payload prior to computing the CRC. Additionally, or alternatively, the UE 115 and the network entity 105 may reverse an order of information bits of the payload prior to computing the CRC. Additionally, or alternatively, the UE 115 and the network entity 105 may use a HARQ size-specific CRC computation function to compute the CRC such that a CRC function for a relatively larger HARQ message may be different from a CRC function for a relatively shorter HARQ message. Accordingly, the network entity 105 may not incorrectly decode HARQ messages based on a HARQ size mismatch, which may increase reliability of the wireless communications system by improving coordination between devices.

[0073] Figure 2 shows an example of a signaling configuration 200 that supports techniques for feedback message payload size correction. The signaling configuration 200 may implement or may be implemented by aspects of the wireless communication system 100. For example, the signaling configuration 200 may be implemented by a UE 115 (e.g., aUE 115-a) or a network entity 105 (e.g., a network entity 105-a), which may be examples of the corresponding devices as described with reference to Figure 1.

[0074] In some examples of the signaling configuration 200, a network entity 105-a may transmit control signaling (e.g., DCI 215, a system information block (SIB), an RRC message, a medium access control-control element (MAC-CE)) and one or more transmissions 220 (e.g., data messages, physical downlink shared channel (PDSCH) transmissions, code blocks) to a UE 115-a via a downlink channel 205. In some examples, the UE 115-a may transmit, via an uplink channel 210, a feedback message 230 (e.g., a message including HARQ feedback information) to the network entityAttorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO22105-a that indicates whether the UE 115-a received one or more transmissions 220. For example, the feedback message 230 may include ACK information for one or more transmissions 220 that were successfully received and decoded by the UE 115-a and NACK information for one or more transmissions 220 that were not successfully received and decoded by the UE 115-a. The network entity 105-amay accordingly transmit one or more retransmissions 225 of the transmissions 220 that were not successfully received.

[0075] In some examples, to increase a likelihood that the network entity 105-a may successfully receive and decode the feedback message 230 (e.g., an uplink control information (UCI) message), the UE 115-a may encode the feedback message 230 using a polar encoding scheme. For example, the UE 115-a may input a set of bits (e.g., a set of information bits and a set of frozen bits with a set value) into a corresponding set of channels. The channels may output an encoded set of bits that include information about the input set of bits (e.g., via one or more exclusive-OR (XOR) operations performed on the set of channels). The encoded set of bits may include relatively more information related to some channels (e.g., a first subset of channels) and relatively less information related to some other channels (e.g., a second subset of channels). Accordingly, to increase a likelihood that the network entity 105-a may successfully receive the set of information bits, the UE 115-a may input the information bits (e.g., and one or more bits related to performing integrity checks and the like, such as parity bits or a CRC) into the first subset of channels and the set of frozen bits into the second subset of channels.

[0076] In some examples, the network entity 105-a may output control signaling that indicates a size of the feedback message 230 (e.g., a Type2 dynamic HARQ-ACK code block). In such examples, if the UE 115-a misses the control signaling (e.g.. a DCI 215), the network entity 105-a may not correct the size of the feedback message 230 (e.g., via a downlink assignment index (DAI)). The UE 115-a may therefore transmit a feedback message 230 that is a different size than a feedback message 230 expected by the network entity 105-a. For example, the network entity 105-a may assume a larger code block size than the UE 115-a.

[0077] In some examples, if a total payload size of the feedback message 230 is larger than or equal to a threshold size (e.g., 12 bits), the UE 115-a may append a first CRC with a length E to the payload. In some examples, the first CRC may be a set ofAttorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO23bits used to confirm that a receiving device (e.g., the network entity 105-a) correctly decoded the payload. For example, the network entity 105-a may generate a second CRC based on a decoded payload, and may compare the second CRC with the first CRC. If the second CRC is the same as the first CRC. the network entity 105-a may assume that the pay load is correctly decoded. If the second CRC is different from the first CRC, the network entity’ 105-a may assume that the payload is incorrectly decoded.

[0078] The UE 115-a may perform polar coding to encode the code block and CRC to generate the feedback message 230. In some examples, the UE 115-a may generate such a CRC using a CRC computation function. The CRC computation function may output a same CRC for a message with a payload of [al, a2, . . . aN] as for a message with a payload of [0, 0, 0, al, a2, . . . aN], That is, one or more 0’s appended to the beginning of a message may not change an output of the CRC generation function.

[0079] Accordingly, if the network entity 105-a expects a message with a relatively longer payload than the UE 115-a (e.g., due to the UE 115-a missing the control signaling indicating for the UE 115-a to use a larger HARQ payload size), the network entity may incorrectly decode the feedback message 230. For example, the network entity 105-a may assume that one or more frozen bits associated with the polar encoding (e.g., bits that were set to 0 as part of the polar encoding) are one or more first bits of the feedback message 230. As an illustrative example, if the UE 115-a outputs a payload of [al, a2, . . . aN] and if channel conditions are relatively good such that the network entity 105-a may receive frozen bits transmitted on relatively lower quality channels, the network entity 105-a may interpret the payload as [0, 0, 0, al, a2, . . . aN] (e.g., due to treating some of the frozen bits as unknown information bits). The network entity 105-a may generate a second CRC based on the payload of [0, 0, 0, al, a2, . . . aN], which may be the same as a first CRC generated by the UE 115-a based on the payload of [al, a2, . . . aN], The network entity 105-a may therefore incorrectly determine that the payload has been successfully decoded, which may result in a NACK to ACK errors or ACK to NACK (A2N) errors that may not be resolved via lower layer signaling.

[0080] In other w ords, the CRC may not prevent the network entity 105-a from miscoding a code block size when polar coding is used to encode and decode the feedback message 230. For example, the network entity 105-a may interpret the frozen bits (e g., 0’s) as NACKs, and may misinterpret one or more bits of the payload asAttorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO24ACKs Such NACK to ACK errors may prevent the network entity 105-a from retransmitting one or more missed transmissions 220, which may reduce a reliability of the signaling configuration 200.

[0081] In some aspects, to prevent incorrect decoding of feedback message 230 due to such a payload size mismatch, the UE 115-a and the network entity 105-a may append a quantity of bits set to a value of 1 to a beginning of a pay load of the feedback message. For example, for a UCI payload of [al , a2, . . . aN], the UE 115-a may compute the first CRC using a set of bits [1, 1, . . . 1, al, a2, . . . aN]. In some examples, a quantity of 1 's appended to the payload may be greater than or equal to a length of the first CRC. Accordingly, if the network entity 105-a interprets the one or more frozen bits as part of the pay load, the network entity 105-a may generate the second CRC using a set of bits [1, 1, . . . 1, 0, 0, . . . 0, al, a2, . . . aN], which may not result in a same CRC as the set of bits [1, 1, . . . 1, al, a2, . . . aN]. The network entity 105-a may therefore not pass a CRC check (e.g., by comparing the first CRC with the second CRC) if there is a HARQ-ACK code block size mismatch.

[0082] In some aspects, the appended quantity of bits may include one or more values that are different from 1. For example, the UE 115-a and the network entity 105-a may append a quantity of bits to the beginning of the feedback message, and a last bit of the quantity of bits may be set of a value of 1. The remaining bits of the quantity of bits may be set according to another sequence (e.g., arbitrarily, according to a preconfigured binary sequence, based on an identifier (ID) of the UE 115-a, based on a cell ID of the network entity 105-a). As an illustrative example, for a UCI payload of [al, a2, . . . aN], the UE 115-a may compute the first CRC using a set of bits [xl, x2, ... xN, 1, al, a2. . . . aN], where [xl, x2, ... xN] is another sequence of bits. The network entity 105-a may append the bits [xl, x2, ... xN, 1] to a beginning of a received UCI to generate the second CRC.

[0083] In such examples, the network entity 105-a may not obtain information indicated via the payload of the feedback message 230 if there is a HARQ-ACK code block size mismatch. The network entity 105-a may accordingly assume that the transmissions 220 were not received, which may result in one or more A2N events (e.g., ACK to NACK errors). The network entity 105-a may accordingly retransmit all of the transmissions 220, which may increase an overhead of the signaling configuration.Attorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO25

[0084] Additionally, or alternatively, in some aspects, the UE 115-a and the network entity 105-a may reverse an order of bits in a pay load of the feedback message. For example, for a UCI payload of [al, a2, . . . aN], the UE 115-a may compute the first CRC using a set of bits [aN, . . . a2, al], The UE 115-a may encode the reversed payload and the CRC according to a polar coding scheme as described herein. For example, the UE 115-a may append the CRC to an end of the reversed payload [aN, . . . a2, al], and may encode the reversed payload appended with the CRC. Accordingly, if the network entity 105-a interprets the one or more frozen bits as part of the payload, the network entity 105-a may generate the second CRC using a set of bits [0, 0, . . . 0, aN, . . . a2, al]. In such examples, the second CRC may be the same as the first CRC. Accordingly, the network entity 105-a may correctly decode bits [al, a2, . . . aN], and may interpret the frozen bits as NACKs for one or more missed grants in the decoded payload. In other words, the frozen bits may pad the payload with one or more NACKs. Such techniques may reduce a quantity of A2N errors, and may enable the network entity7105-a to transmits retransmissions 225 of the missed grants (e.g., and one or more missed transmissions 220 indicated via the feedback message 230).

[0085] In examples in which the UE 115-a multiplexes the feedback message 230 with one or more additional UCI messages (e.g., channel state information (CSI) messages, scheduling requests (SRs)), the UE 115-a may encode the feedback message 230 and the one or more additional UCI messages with the one or more additional UCI messages located sequentially after the reversed payload of the feedback message 230. For example, for a set of bits [bl, . . . bK] of an additional UCI message, the UE 115-a may encode and transmit a set of bits [aN, . . . a2, al, bl, . . . bK] appended with a CRC that is computed based on the set of bits [aN, . . . a2, al, bl, . . . bK]. The UE 115-a may compute the CRC and may append the computed CRC to the end of the set of bits [aN, . . . a2, al, bl, . . . bK], and may encode the set of bits and the appended CRC. The network entity 105-a may accordingly pad one or more zeros (e.g., frozen bits) sequentially before the reversed payload of the feedback message 230, which may not reduce a reliability of decoding the additional UCI message.

[0086] Additionally, or alternatively, in some aspects, the UE 115-a and the network entity' 105-a may compute CRCs using a CRC computation function that is associated with (e.g., a function of) a size of the payload of the feedback message 230. ForAttorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO26example, the UE 115-a and the network entity 105-a may apply a scrambling (e.g., a CRC mask) to the CRC bits that is based on the HARQ-ACK code block size, or may use a CRC polynomial (e.g., with a same CRC length) that is based on the HARQ-ACK code block size. Accordingly, the network entity 105-a may decode the feedback message 230 (e.g., using the polar coding scheme) based on a code block size that is scheduled by the network entity 105-a.

[0087] The network entity 105-a may generate a second CRC based on the code block size that is scheduled by the network entity 105-a. If the CRC passes (e.g., if the second CRC is the same as the first CRC of the feedback message 230), the network entity 105-a may assume that the feedback message 230 is successfully decoded and may determine feedback information indicated by the pay load. If the CRC does not pass (e.g., if the second CRC is not the same as the first CRC of the feedback message 230), the network entity 105-a may generate a third CRC based on a different code block size (e.g., a code block size that was previously configured for the UE 115-a). and may perform an additional comparison of the first CRC with the third CRC. The network entity' 105-a may determine the HARQ-ACK code block size transmitted by the UE 115-a based on whether the second CRC or the third CRC is the same as the first CRC.

[0088] In some examples, a quantity' of sizes of the feedback message 230 (e.g., a quantity of HARQ-ACK code block sizes) may be variable (e.g., depending on a quantity of grants missed by the UE 115-a). Accordingly, the code block size-specific CRC scrambling or polynomial may be associated with a modulo operation of a code block size hypothesis. As an illustrative example, the UE 115-a and the network entity 105-a may be configured with two CRC masks (e.g., a first CRC mask and a second CRC mask, which may be defined according to a rule). The UE 115-a and the network entity 105-a may use the first CRC mask when the code block size is an even quantity of bits, and the second CRC mask when the code block size is an odd quantity of bits. In such an example, if the UE 115-a is configured with a code block size of 20 and the UE 115-a misses a first grant indicating a code block size of 21, the UE 115-a may transmit the feedback message 230 with the code block size of 20 with a first CRC that is scrambled using the first CRC mask. The network entity 105-a may decode the feedback message 230 assuming a code block size of 21, and may compute and scramble the second CRC using the second CRC mask. The second CRC may not passAttorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO27(e.g., may be different from the first CRC). The network entity 105-amay compute and scramble a third CRC using the first CRC mask, which may be the same as the first CRC.

[0089] The network entity7105-a may accordingly determine that the code block size used by the UE 115-a is an even number. In some examples, the network entity 105-a may determine that a most recently configured code block size is relatively more likely to be the code block size used by the UE 115-a. Referring again to the previous example, the network entity7105-a may assume that the UE 115-a used a code block size of 20, and may determine that the UE 115-a missed at least one grant (e.g., a grant indicating the code block size of 21).

[0090] The described techniques may accordingly prevent the network entity 105-a from incorrectly determining that a payload of a feedback message 230 has been successfully decoded. Such techniques may enable relatively improved reliability7in the signaling configuration 200 by reducing a quantity7of NACK to ACK errors.

[0091] Figure 3 shows an example of a process flow 300 that supports techniques for feedback message payload size correction. The process flow 300 may implement or may be implemented by aspects of the wireless communication system 100 or the signaling configuration 200. For example, the process flow 300 may be implemented by a UE 115 (e.g., a UE 115-b) or a network entity 105 (e.g., a network entity 105-b), which may be examples of the corresponding devices as described with reference to Figure 1.

[0092] In the following description of the process flow 300, the operations between the UE 115-b and the network entity 105-b may occur in a different order than the example order shown and, in some examples, may be performed by one or more different devices other than those shown as examples. Some operations also may be omitted from the process flow 300, and other operations may be added to the process flow 300. Further, although some operations or signaling may be shown to occur at different times for discussion purposes, these operations may actually occur at the same time.

[0093] In some examples, at 305, the network entity 105-b may output, to the UE 115-b, control signaling indicating a size of a HARQ feedback message. For example,Attorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO28the control signaling may indicate for the UE 115-b to switch from using a first feedback message size (e.g., a first quantity of bits for feedback information) to a second feedback message size (e.g., a second quantity of bits for feedback information).

[0094] At 310, the network entity 105-b may output, to the UE 115-b, a DCI message that schedules one or more transmissions (e.g., downlink transmission, physical downlink shared channel (PDSCH) messages, code blocks) from the network entity’ 105-b. At 315, the network entity 105-b may output (e.g., and the UE 115-b may monitor for) the one or more transmissions.

[0095] At 320, the UE 115-b may compute a feedback message associated with the one or more transmissions. For example, the UE 115-b may generate a second set of bits indicating whether the UE 115-b received the one or more transmissions based on the monitoring. In examples in which the UE 115-b did not receive one or more of the one or more transmission, the feedback information may indicate the one or more missed transmission.

[0096] The UE 115-b may compute, using the second set of bits, a first set of bits comprising a first CRC. In some examples, the UE 115-b may modify the first set of bits to obtain the CRC. For example, the UE 115-b may append a set of ones (e.g., 1 's) to the first set of bits before inputting the second set of bits into a CRC computation function. Additionally, or alternatively, the UE 115-b may reverse an order of the second set of bits before inputting the first set of bits into the CRC computation function. Additionally, or alternatively, the UE 115-b may use a first CRC computation function (e.g., a polynomial or a CRC mask) associated with a size of the second set of bits (e.g., or a size of a HARQ feedback message including the second set of bits) to compute the CRC, where the first CRC computation function is different from a second CRC computation function associated with a second size of the second set of bits (e.g., or a second size of the HARQ feedback message).

[0097] At 325, the UE 115-b may encode the feedback message including the first set of bits and the second set of bits to generate a feedback message (e.g.. a HARQ feedback message). In examples in which the UE 115-b reversed the second set of bits to generate the first set of bits, the UE 115-b may encode the reversed second set of bits and the second set of bits. The UE 115-b may encode the feedback message according to an encoding scheme (e.g., a polar encoding scheme).Attorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO29

[0098] At 330, the UE 115-b may transmit the HARQ feedback message to the network entity 105-b. In some examples, the UE 115-b may multiplex the HARQ feedback message with one or more UCI messages. In such examples, a third set of bits that are representative of the one or more UCI messages may be located sequentially after the second set of bits (e.g., the reversed second set of bits).

[0099] At 335. the network entity 105-b may decode the feedback message to generate the first set of bits and the second set of bits. For example, the network entity 105-b may decode the feedback message using a decoding scheme (e.g., a polar decoding scheme).

[0100] At 340, the network entity 105-b may determine the feedback information. In some examples, the network entity 105-b may generate a second CRC based on the decoded second set of bits. For example, the network entity 105-b may generate the second CRC based on the reversed second set of bits or based on appending a quantity of l’s to the second set of bits (e.g., in accordance with a CRC generation method used by the UE 115-b). Additionally, or alternatively, the network entity 105-b may generate the second CRC using the first CRC computation function associated with a size of the second set of bits (e.g., or a size of a HARQ feedback message including the second set of bits) to compute the CRC. For example, the network entity 105-b may use a CRC computation function associated with the HARQ feedback message size indicated via the control signaling.

[0101] In some examples, the network entity 105-b may determine that the first CRC is different from the second CRC based on comparing the first CRC and the second CRC. In such examples, the network entity 105-b may determine that the UE 115-b did not receive the control signaling indicating the HARQ feedback message size. In examples in which the network entity 105-b is configured with the first CRC computation function and the second CRC computation function, the network entity 105-b may generate a third CRC using the second CRC computation function, and may compare the first CRC with the third CRC. Additionally, or alternatively, in response to the first CRC being different from the second CRC, the network entity 105-b may determine that the UE 115-b did not receive the one or more transmissions.

[0102] In some examples, if the first CRC is the same as the second CRC (e.g., or the third CRC), the network entity 105-b may successfully determine the feedback Attorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO30information. The network entity 105-b may accordingly determine whether the UE 115-b received the one or more transmissions.

[0103] In examples in which the feedback information indicates that the UE 115-b did not receive one or more of the transmissions (e.g., or if the network entity 105-b does not determine the feedback information based on the first CRC being different from the second CRC). at 345. the network entity 105-b may retransmit some or all of the one or more transmissions. For example, the network entity 105-b may retransmit the one or more missed transmissions indicated by the feedback information or all of the one or more transmissions. The UE 115-b may accordingly receive the retransmissions.

Specifically, unless a phrase refers to “associated with only ‘a,’” or the equivalent in context, whatever it is that is “associated with ‘a,’” may be associated with “a” alone or associated with a combination of "a" and one or more other conditions, factors, criteria, elements, components or actions, among other examples. The phrase “associated with” may be interpreted to mean or be interchanged with “in association with,” “in accordance with,” “based on,” “based at least in part on,” “as a function of,” “in response to,” “responsive to.” “using,” “coupled with.” in communication with,” “configured with,” “included with,” or “in cooperation with,” as appropriate in the relevant context unless otherw ise explicitly indicated. Additionally, the use of such phrases does not indicate that what follows the phrase is the focal point or primary factor associated with the limitation preceding the phrase.

[0241] As used herein, a phrase referring to “at least one of’ or “one or more of’ a list of items refers to any combination of those items, including single members. For example, “at least one of: a, b, or c” is intended to cover: a, b, c, a-b, a-c, b-c, and a-b-c. Additionally, as used herein, a phrase referring to “a” or “an” element refers to one or more of such elements acting individually or collectively to perform the recitedAttorney Docket No. PY2962.WO (114958.6452)Qualcomm Docket No 2500288WO55function(s). Thus, the terms “a,” “at least one,’’ “one or more,” and “at least one of one or more” may be interchangeable. For instance, for a claim that refers to “a” component performing one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components, and subsequent reference to a component introduced with the article “a” using the term “the” may refer to any or all of the single or multiple components. Thus, a component introduced with the article “a” may be understood to mean “one or more” components, and referring to “the” component subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more” components. Additionally, as used herein, a “set” can refer to one or more items, and a “subset” can refer to a whole set or less than the whole set, but not an empty set. Additionally, as used herein, the term “or” is intended to be interpreted in the inclusive sense, such as when referring to a series, and may be used interchangeably with the term “and / or.” unless otherwise explicitly indicated (for example, if used in conjunction with “either” or “only one of’). For example, “a or b” may include a only, b only, or a combination of a and b.
