Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for retransmission and selection of HARQ and MCS based on partial sensing. A UE may perform a partial sensing procedure to identify one or more available resources for a sidelink transmission of the UE and transmit the sidelink transmission on a resource selected from the one or more available resources. The sidelink transmission may include at least one of a HARQ retransmission parameter or an MCS selected for the sidelink transmission based on at least one of a number of candidate slots for the partial sensing procedure, a quantity of the one or more available resources within the number of candidate slots, or a number of times that a threshold for a minimum amount of the one or more available resources is increased.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, within a synchronization resource set, synchronization resources to use to transmit a UE-specific sidelink synchronization signal. The UE may transmit the UE-specific sidelink synchronization signal using the synchronization resources included in the synchronization resource set. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a payload for inclusion in an uplink transmission. The UE may organize the payload into a code block group (CBG) that includes one or more code blocks (CB). The UE may map each CB of the CBG to a corresponding uplink shared channel resource unit (e.g., a physical uplink shared channel resource unit) of an uplink transmission occasion of the first UE. The uplink transmission occasion may also be shared with one or more additional UEs such that the CBG of the first UE is multiplexed with additional CBGs from the additional UEs. The UE may transmit, to a base station, the uplink transmission including each uplink shared channel resource unit on which the CBG is organized.

Abstract: To facilitate coexistence of a first radio access technology (RAT) and a second RAT, methods, apparatuses, and computer program products are provided. An example method of a first wireless device operating based on a RAT includes receiving a sidelink resource reservation from a second wireless device based on a second RAT, the sidelink resource reservation indicating a first set of resources. The example method further includes determining whether to exclude, from a candidate resource set for the first RAT within a sidelink resource pool for the first RAT, resources that overlap with the set of reserved resources for the second RAT. The example method further includes transmitting a sidelink transmission using one or more sidelink transmission resources selected from the candidate resource set in the sidelink resource pool for the first RAT.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, at a first transmission reception point, a first transmission from a second UE associated with communications between the second UE and a third UE. The first UE may receive, at a second transmission reception point, a second transmission. The first UE may identify transmissions having overlapping time-frequency resources based on receiving the first transmission and the second transmission. In some examples, the identified transmissions may include the first transmission and the second transmission. Additionally or alternatively, the identified transmissions may include a third transmission and a fourth transmission. The first UE may transmit an interference mitigation signal to the second UE. The interference mitigation signal may include an indication to orthogonalize one or more reference signals, a negative acknowledgment indication, or both.

Abstract: An apparatus may be configured to receive a polar-encoded transmission comprising at least one intermediate node associated with a first configuration of frozen leaf nodes and information leaf nodes. The apparatus may further be configured to apply an FHT to a first set of values associated with a first intermediate node of the at least one intermediate node to generate a second set of values associated with the first intermediate node. The apparatus may also be configured to select, based on the second set of values, one or more paths associated with the first intermediate node for a SSCL decoding. The apparatus may further be configured to calculate a path metric for each of the selected one or more paths associated with the first intermediate node.

Abstract: Techniques for wireless communications are described. A communication device, such as a user equipment (UE) may determine a resource usage level in a wireless communications system. Additionally or alternatively, the UE may determine a transmission property associated with sidelink communication at the UE. The UE may adjust, based on the determined resource usage level in the wireless communications system or the determined transmission property associated with the sidelink communication at the UE, or a combination thereof, a sensing mode of a sensing procedure or a sensing parameter of the sensing procedure, or a combination thereof. In some examples, the UE may identify a set of resources used for the sidelink communication at the UE based on the adjusted sensing mode or the adjusted sensing parameter, or a combination thereof. The UE may perform the sidelink communication based on the sensing mode or the sensing parameter, or a combination thereof.

Abstract: Aspects relate to techniques for MCS selection of a packet to be network coded for sidelink communication. A transmitting UE may encode a packet using an MCS that is greater than a normal MCS that may be used for encoding the packet without network coding. The transmitting UE may then transmit the encoded packet to one or more receiving UEs and a network coding device over a sidelink data channel. The transmitting UE may further transmit a network coding request flag associated with the packet to initiate one or more retransmissions of the packet by the network coding device.
