Abstract: A method and apparatus for prioritization of sidelink and uplink. The apparatus compares priorities of a first group of transmission signals to determine a first signal from the first group of transmission signals having a highest priority. The first group of transmission signals comprise at least one uplink signal and at least one sidelink transmission signal. The apparatus compares a priority of the first signal from the first group of transmission signals against a reception signal having a highest priority of a second group of reception signals to determine to transmit at least the first signal from the first group of transmission signals or to receive at least one reception signal from the second group of reception signals. The second group of reception signals comprises at least one sidelink reception signal.

Abstract: Certain aspects of the present disclosure provide techniques for multiplexing HARQ feedback in a same slot for downlink and sidelink transmissions. An example method generally includes receiving, from a network entity, a downlink control information (DCI) that schedules resources for at least one physical sidelink shared channel (PSSCH) transmission from the first UE to a second UE, transmitting data to the second UE via the at least one PSSCH transmission using the scheduled resources, receiving, from the second UE, acknowledgment feedback for the at least one PSSCH transmission, selecting at least one codebook entry for providing feedback for at least one downlink transmission from the network entity to the first UE and the acknowledgment feedback for the at least one PSSCH transmission in a same physical uplink control channel (PUCCH) slot, and transmitting the at least one codebook entry to the network entity via at least one PUCCH transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may determine a set of resources available for transmission of one or more reference signals (e.g., one or more PRSs) in a shared radio frequency spectrum band (e.g., an unlicensed radio frequency spectrum band) in a time interval for sidelink positioning. The UE may transmit, in a second radio frequency spectrum, a control message reserving the set of resources for the UE to transmit the one or more reference signals in the time interval for sidelink positioning. The UE may transmit the one or more reference signals on the set of resources based on transmitting the control message reserving the set of resources.

Abstract: Apparatus, methods, and computer-readable media for sidelink control information forwarding for sensing procedure are disclosed herein. An example method of wireless communication at a forwarding user equipment (UE) includes receiving, from a forwarded UE, control information, and transmitting, to a sensing UE, a forward message including the control information and information associated with the forwarded UE. An example method of wireless communication at the sensing UE includes receiving, from the forwarding UE, a forward message including the control information containing a first measurement of the control information. The example method also includes obtaining a second measurement of the forward message and determining a ratio of the second measurement to the first measurement. The example method also includes selecting a specific resource based on the ratio and whether the forwarding UE is an intended receiver for the sensing UE or the forwarding UE intends to receive from the forwarded UE.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive scheduling information that schedules an uplink data message over a high priority physical uplink shared channel (PUSCH) that overlaps in time with a physical uplink control channel (PUCCH) resource over which the UE is scheduled to transmit feedback associated with sidelink communication. The UE may receive signaling from a base station indicating whether the feedback associated with the sidelink communication can be multiplexed with the uplink data message on the high priority PUSCH. As such, the UE may multiplex the feedback associated with the sidelink communication on the high priority PUSCH if the signaling from the base station indicates that the feedback associated with the sidelink communication can be multiplexed with the uplink data message on the high priority PUSCH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE, a resource reservation that indicates a reservation for one or more resources; and transmit an indication that at least one resource of the one or more resources is in conflict with an additional resource reservation, the indication including one or more of an identification of the at least one resource, an identification of the resource reservation, or an identification of the second UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit, within an active duration of a first sidelink discontinuous reception (DRX) pattern of a second UE, sidelink control information (SCI) indicating a resource reservation for a sidelink resource of the sidelink channel within at least a portion of an inactive duration of the first sidelink DRX pattern. The first UE may then communicate, with the second UE via the sidelink channel, a sidelink message within the sidelink resource indicated in the resource reservation.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may identify a set of resources for communication with a second UE, wherein the set of resources includes a subset of resources overlapping with a discontinuous reception (DRX) mode on duration of the second UE. The first UE may communicate with the second UE using one or more resources of the set of resources. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) or multiple UEs may transmit a grant-free uplink transmission to a base station. The base station may monitor resources for the grant-free uplink transmission (e.g., from one or more UEs) and the base station may generate a group feedback message corresponding to whether the base station successfully received the uplink transmission(s). The group feedback message may contain feedback for multiple uplink transmissions from one or multiple UEs. The group feedback message may be transmitted to a UE over a downlink shared channel or a downlink control channel and the UE may receive the group feedback message and may determine whether to retransmit the uplink transmission based on the group feedback message.

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.
