Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving, from a network device, an initial transmission parameter that indicates whether a network coding function is enabled for initial transmissions from a first radio link control (RLC) entity associated with a multicast radio bearer (MRB) of a network device and a retransmission parameter that indicates whether the network coding function is enabled for retransmissions from a second RLC entity associated with the MRB. The method also includes receiving a set of initial data units from the first RLC entity. The method further includes receiving, from the second RLC entity, a set of retransmission data units based on transmitting status indicators that indicate the set of initial data units satisfy a failure condition.

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: A terrestrial UE may receive at least one of a PEI or a paging indication based on a configuration for a search space associated with the at least one of the PEI or the paging indication and transmit a message to a network node via an aircraft-based relay node based on the at least one of the PEI or the paging indication. The relay node may transmit the at least one of the PEI or the paging indication to the terrestrial UE or receive the at least one of the PEI or the paging indication from an NTN device. The relay node may receive the message from the terrestrial UE based on the at least one of the PEI or the paging indication and relay the message to the network node after receiving the message from the terrestrial UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first device may transmit a message indicating that the first device is operating on intermittently available energy harvested from outside the first device. The first device may receive a low-power wakeup signal. The first device may transmit, based at least in part on an energy harvesting state of the first device, an indication that the first device is capable of supporting continuous transmission and reception during a time frame having a configured duration. The first device may communicate during the time frame. Numerous other aspects are described.

Abstract: In an aspect, a network device may transmit one or more first sets of first chirp signals in a first bandwidth of an allocated frequency range assigned to the network device for data communications and sensing signals. The network device may transmit one or more second sets of second chirp signals in a second bandwidth of the allocated frequency range, wherein the second bandwidth is larger than the first bandwidth.

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.
