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: 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.

Abstract: Aspects described herein relate to encoding wireless communications using feedback from receiving devices to achieve an adaptive coding rate, which can include generating, for a set of source symbols representing data to be transmitted in a broadcast channel, a set of encoded symbols for transmitting in the broadcast channel, transmitting a first number of the set of encoded symbols over the broadcast channel, requesting, based on transmitting the first number of the set of encoded symbols, feedback from a set of user equipment (UEs), and determining, based at least in part on the feedback, whether to continue transmitting a second number of the set of encoded symbols or begin transmitting a new set of encoded symbols representing new data to be transmitted in the broadcast channel.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may encode, at a layer two (L2) layer of the transmitting device, a set of service data units (SDUs) according to a set of network coding parameters to obtain a first set of protocol data units (PDUs). The transmitting device may transmit, to one or more receiving devices, the first set of PDUs. The transmitting device may receive, from a receiving device of the one or more receiving devices, a report indicating an SDU of the set of SDUs that was unsuccessfully received at the receiving device. The transmitting device may transmit, to the one or more receiving devices, based at least in part on the received report, a second set of one or more PDUs corresponding to at least the SDU of the set of SDUs.

Abstract: Methods, systems, and devices for wireless communications are described. The techniques described herein relate to control signaling for multiple radio access technology (RAT) carrier aggregation. A user equipment (UE) receives downlink control information (DCI) for a first RAT (e.g., 5G) and/or a second RAT (e.g., 6G), in a downlink control channel of the first RAT. The UE determines whether the DCI is associated with the first RAT or the second RAT by monitoring different search spaces, different control resource sets (CORESETs), different radio network temporary identifiers (RNTIs), different DCI lengths, different indication fields of the DCI, different capability parameters, and/or wake-up signals, that are associated with the downlink control channel communicated via the first RAT. The UE 115 communicates via the second RAT based on receiving the DCI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, a capability report indicating one or more capability parameters that are associated with wideband interference measurement of an orthogonal frequency division multiplexing (OFDM) channel and a supported subband size for the OFDM channel. The UE may receive, from the network node, configuration information indicating an interference measurement resource associated with a set of frequency domain resources, wherein the set of frequency domain resources includes a greater number of frequency domain resources than the supported subband size. The UE may measure, based on the reception of the configuration information, the interference measurement resource to obtain interference measurement information associated with the OFDM channel. The UE may transmit, to the network node, a measurement report indicating the interference measurement information. Numerous other aspects are described.

Abstract: Some techniques described herein provide indication of a preferred scheduling mode for a user equipment (UE) based at least in part on an energy harvesting state of the UE. For example, the preferred scheduling mode may indicate a configured grant scheduling mode or a dynamic grant scheduling mode and/or one or more parameters associated with the preferred scheduling mode. For example, the one or more parameters may be based at least in part on an energy harvesting state of the UE. By indicating the preferred scheduling mode, the UE can selectively perform a transmission using a dynamic grant resource or a configured grant resource. Thus, the UE can request a dynamic grant resource when the UE is associated with a high energy level or a relatively fast charging rate, or a CG resource when the UE is associated with a low energy level ora relatively slow charging rate.
