Abstract: Certain aspects of the present disclosure provide a method for wireless communication at a first user equipment (UE). The method generally includes receiving, from a second UE, sidelink control information (SCI) scheduling a physical sidelink shared channel (PSSCH), determining a sequence for providing feedback for the PSSCH, from a plurality of possible sequences, based on one or more parameters, and transmitting the sequence via a physical sidelink feedback channel (PSFCH) as feedback for the PSSCH.

Abstract: Apparatus, methods, and computer program products for handover of transport blocks (TBs) for network coding are provided. An example method may include receiving, from a user equipment (UE), a transport block (TB) associated with a networking coding request. The example method may further include transmitting, based on at least one of first movement information of the UE, second movement information of one or more recipients of the TB, or a TB load of the first network coding device being above a threshold, a handover request message to a network entity for handover of the TB to a second network coding device. The handover request message may be for a handover of the TB to a second network coding device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain a first indication, based at least in part on a first threshold, that a hybrid automatic repeat request (HARQ) discontinuous transmission (DTX) is caused by a listen-before-talk (LBT) failure. The UE may obtain a second indication, based at least in part on a second threshold, that the HARQ DTX caused by the LBT failure is a type of HARQ DTX that is to be counted for identifying a sidelink radio link failure (RLF). The UE may identify the sidelink RLF based at least in part on detecting a number of consecutive occurrences of the type of HARQ DTX occurrences. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE, an initial transmission of a transport block via a sidelink unlicensed band. The UE may receive, from the second UE, a negative acknowledgement (NACK) based at least in part on the initial transmission of the transport block. The UE may transmit, to the second UE and based at least in part on the NACK and a retransmission reservation, a retransmission of the transport block via the sidelink unlicensed band in a retransmission occasion of a plurality of retransmission occasions associated with the retransmission reservation. Numerous other aspects are described.

Abstract: According to a first method, a first user equipment (UE) may receive sidelink control information (SCI) over a sidelink communication link between the first UE and a second UE. The SCI may indicate a precoding resource block group (PRG) size associated with sidelink communications with the second UE. The first UE may determine the PRG size for communications over the sidelink communication link based at least in part on the SCI. The first UE may then receive a sidelink message from the second UE via the sidelink communication link based on the determined PRG size, and may transmit a sidelink message to the second UE based on the determined PRG size. According to a second method, a first user equipment may identify a sidelink configuration for a sidelink communication link between the first UE and a second UE, determine a PRG size for communications over the sidelink communication link based at least in part on the sidelink configuration, and receive, from the second UE, a sidelink message based at least in part on the PRG size.
