Abstract: Apparatus, methods, and computer-readable media for network coding for dual connectivity are disclosed herein. A base station (BS) sends encoded symbols from a first network coding layer to a first radio link control (RLC) layer and transmits, to a user equipment (UE), encoded data comprising the encoded symbols. The BS also transmits encoded data to a road side unit (RSU) for passing to the UE as a split transmission. The UE can receive encoded packets from the BS and RSU at a network coding layer via a second RLC layer. The UE recovers source packets from the encoded packets with a rateless network code at the network coding layer. The UE sequences the source packets into an ordered set of source packets at the network coding layer and sends the ordered set of source packets from the network coding layer to a packet data convergence protocol layer for processing.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver may determine that a quantity of a first plurality of radio link layer (RLC) protocol data unit (PDU) packets, received from a transmitter, satisfies a first quantity threshold. The receiver may perform a decoding attempt for the first plurality of RLC PDU packets based at least in part on the determination. The receiver may transmit, to the transmitter, an RLC layer feedback report for the first plurality of RLC PDU packets. The RLC layer feedback report may be based at least in part on the decoding attempt. Numerous other aspects are provided.

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: 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.
