Abstract: Methods, systems, and devices for wireless communications are described that provide for multi-RAT spectrum sharing (MRSS) for network access procedures. MRSS may provide common resources for initial access information for each of two or more RATs. In some aspects, an initial bandwidth part (BWP) configuration may be provided for a MRSS cell, and a user equipment (UE) supporting MRSS, as well as UEs that support only one RAT (e.g., a legacy UE that supports an older technology RAT), may monitor for network access information in the common resources, such as a synchronization signal block (SSB) that provides access information for two RATs.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for RLC buffer reduction techniques. A wireless transmitter may generate at least one RLC PDU and at least one RLC parity PDU based on an encoding procedure for an RLC SDU. The wireless transmitter may store, in an RLC buffer, the at least one RLC parity PDU for the RLC SDU and transmit, to a MAC layer, at least one of the segmentation of the RLC SDU or the at least one RLC PDU. A wireless receiver may generate RLC PDU feedback for at least one of the RLC SDU, the segmentation of the RLC SDU, or the at least one RLC PDU and transmit, to an RLC layer, the RLC PDU feedback including an indication of an additional number of encoded RLC PDUs and at least one of an ACK_SN or a NACK_SN.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications system may support compression of channel information (e.g., channel feedback) in accordance with multiple compression schemes, from which a transmitting device may select for a channel reporting transmission. For example, a user equipment (UE) may be configured with multiple channel state information compression schemes, corresponding to different encoders or decoders, which may involve various machine learning or neural network techniques. The UE may select or otherwise determine which compression scheme to use for channel reporting in various scenarios, including a selection based on whether a compression scheme maintains relatively accurate reporting, or whether a more power-intensive or processor-intensive compression scheme is supported by an operating mode of the UE, among other selection criteria. The UE may indicate which compression scheme was selected by a transmitted indication included with or otherwise accompanying a channel reporting transmission.

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.
