Abstract: Aspects are provided for HARQ feedback and retransmission procedures for cooperative relaying in sidelink networks. A relay attempts to decode sidelink data received from a source for relay to a destination. The relay may combine LLRs for the sidelink data and for a retransmission of the sidelink data. The relay determines a resource of a wireless channel for transmitting feedback to the source in response to the decoding attempt. If decoding is successful, the relay transmits the data to the destination. The destination then attempts to decode the data received from the relay. The destination may combine LLRs for the data and for a retransmission of the data. The destination determines a resource of a wireless channel for transmitting feedback to the relay in response to the decoding attempt. The resources are based on a relay identifier associated with the relay.

Abstract: An apparatus is disclosed. The apparatus may determine whether one or more PUCCH resources, one or more second PUCCH resources, or one or more third PUCCH resources of a plurality of PUCCH resources are suitable for at least one uplink transmission. Each of the one or more first PUCCH resources may include a payload capacity equal to a payload threshold. Each of the one or more second PUCCH resources may include a payload capacity greater than the payload threshold. Each of the one or more third PUCCH resources may include a payload capacity less than the payload threshold. The apparatus may transmit, based on the selection of PUCCH resources, the at least one uplink transmission via the selected at least one of the one or more first PUCCH resources, the one or more second PUCCH resources, or the one or more third PUCCH resources.

Abstract: Certain aspects of the present disclosure provide techniques for replacing and/or fixing broken uplink repetitions due to segmentation of nominal repetitions into actual repetitions. A method that may be performed by a user equipment (UE) includes detecting that a configured repetition pattern for uplink transmission to a network entity results in segmentation of at least one nominal repetition into multiple actual repetitions, modifying the configured repetition pattern, based at least in part on the detection, to avoid segmentation of nominal repetitions into multiple actual repetitions, and sending the uplink transmission to the network entity in accordance with the modified repetition pattern.

Abstract: A user equipment (UE) may partition a plurality of channels including physical uplink control channels (PUCCHs) and physical uplink shared channels (PUSCHs) into two groups, the plurality of channels being scheduled for transmission on a first set of component carriers (CCs) for communicating data and a second set of CCs for communicating control information and data, determine a first subset of PUSCHs of the one or more PUSCHs that is in the second set of CCs, determine that a first PUCCH of the one or more PUCCHs overlaps in time with at least a part of at least one PUSCH of the first subset of PUSCHs, and multiplex the first PUCCH with a first PUSCH of the first subset of PUSCH based on the determination that the first PUCCH overlaps in time with at least a part of the at least one PUSCH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a first sounding reference signal (SRS) transmission that occurred most recently in time, relative to a second SRS transmission, prior to transmission of one or more physical uplink shared channel (PUSCH) communications. The one or more PUSCH communications may correspond to a configured grant. The UE may transmit the one or more PUSCH communications using one or more SRS resources associated with the first SRS transmission. Numerous other aspects are provided.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for channel coding techniques based on unequal error protection for multiplexed LP UCI and HP UCI. In aspects, a UE may multiplex a set of LP UCI bits with a set of HP UCI bits. The set of HP UCI bits may be encoded through both a first encoder and a second encoder, and the set of LP UCI bits may be encoded through the second encoder to generate a set of coded UCI bits. The UE may transmit, to a base station, the set of coded UCI bits through one of a PUCCH or a PUSCH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may communicate with one or more second UEs to identify a resource overlap for a resource for relay communication. The first UE may selectively transmit using the resource with the resource overlap in accordance with a random access procedure. Numerous other aspects are described.

Abstract: Aspects relate to mechanisms for wireless communication devices to report sub-band (SB) channel state information (SB-CSI). A UE receives a physical downlink shared channel (PDSCH) transmission from a base station. The UE transmits either an acknowledgement (ACK) transmission or a negative acknowledgement (NACK) transmission to the base station in response to a reception of the PDSCH transmission. The UE determines whether to transmit a sub-band (SB) channel state information (SB-CSI) report to the base station based on whether the ACK transmission is transmitted to the base station or whether the NACK transmission is transmitted to the base station.

Abstract: A method of non-coherent wireless communication performed by a wireless communication device includes generating information bits for transmission to another wireless communication device. The method also includes identifying a configuration for a polar code encoder for encoding the information bits. The method further includes encoding a set of the information bits with a polar code encoding operation based on the configuration to generate a codeword, the configuration rendering the polar code encoding operation incapable of generating a codeword that is a bit-flipped counterpart of another codeword that the polar code encoding operation is capable of generating based on the configuration. The method still further includes transmitting the codeword via a wireless channel without a reference signal.

Abstract: Aspects described herein relate to receiving one or more downlink transmissions from a base station, and transmitting, based on comparing one or more parameter values of the one or more downlink transmissions to one or more threshold values, a sounding reference signal (SRS) to the base station over uplink resources. Other aspects relate to receiving, from a user equipment (UE), feedback related to decoding one or more downlink transmissions, wherein the feedback includes an indication that the UE is transmitting a SRS, and receiving, based on the indication, the SRS from the UE over uplink resources.
