Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, configuration information indicating that network coding is enabled for initial transmissions associated with a multicast/broadcast service (MBS) and indicating that network coding is enabled for retransmissions associated with the MBS. The UE may receive, via a multicast traffic channel or a dedicated traffic channel, an initial transmission associated with the MBS, wherein the initial transmission is associated with a first set of encoded packets. The UE may transmit a radio link control (RLC) status feedback message associated with the initial transmission. The UE may receive, via the multicast traffic channel or the dedicated traffic channel, a retransmission associated with the initial transmission, wherein the retransmission is associated with a second set of encoded packets. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a wireless device may In use non-uniformly distributed bits for amplitude mapping and uniformly distributed bits for sign mapping to support probabilistic constellation shaping (PCS) for transmission of a message. To provide a coding gain with one or more retransmissions of the message, the device may configure redundancy versions based on the non-uniform distribution of one or more symbols. In some examples, the device may include the same set of non-uniformly distributed systematic bits or at least a portion of non-uniformly distributed systematic bits in each redundancy version of the message. Additionally or alternatively, the device may use multiple modulation and coding scheme (MCS) values to modulate one or more of the redundancy versions, where a first MCS value is used to modulate non-uniformly distributed symbols and a second MCS value is used to modulate uniformly distributed symbols.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting (Tx) node may perform a channel measurement in a channel sensing contention slot based at least in part on a measurement time, wherein the measurement time is based at least in part on one or more of a sensing bandwidth or a beam switching time. The Tx may perform, to a receiving (Rx) node, a transmission based at least in part on a value of the channel measurement satisfying a threshold. Numerous other aspects are described.

Abstract: Wireless communication methods and devices for selective receiver-assisted channel sensing are provided. In some aspects, one or more receivers (e.g., UEs) can be selectively configured to perform receiver-assisted channel sensing (e.g., class A channel sensing) using at least one of trigger signaling and channel sensing configuration by a BS, UE capabilities, or operational mode. For example, a method for wireless communication performed by a user equipment (UE) includes: sensing a channel based on at least one of a receiver-assisted channel sensing trigger, or a UE capability; and transmitting, to a base station (BS) based on the sensing, channel sensing information.

Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A user equipment (UE) may receive a configuration indicating a mapping between a set of multiple subband indices and a set of multiple encoding parameter sets. The UE may apply, at a first distribution matcher, a first encoding parameter set to a first subset of a bit stream. The UE may also apply, at a second distribution matcher, a second encoding parameter set to a second subset of the bit stream. The a first encoding parameter set may be associated with a first subband index and the second encoding parameter set may be associated with a second subband index. The UE may then transmit a first modulated bit stream on a first subband, and a second modulated bit stream on a second subband.
