Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may establish multiple unicast connections with multiple other UEs. The first UE may then determine individual sets of transmission parameters for each of the multiple other UEs, where the individual sets of transmission parameters may enable the first UE to receive transmissions from the multiple other UEs on a same set of time and frequency resources via a spatial division multiplexing scheme. For example, each of the individual sets of transmission parameters may include a transmission schedule adjustment, a transmit power, a transmit time, an indication of the time and frequency resources, or a combination thereof. The first UE may then transmit each of the individual sets of transmission parameters to a respective UE of the multiple other UEs.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) to measure self-interference between multiple transmission reception points (TRPs) of the UE and initiate sidelink full duplex communications based on the measured self-interference. The UE may transmit a message to a base station to request resources for sidelink communications by the UE and indicate an intended self-interference measurement by the UE using the resources. The base station may transmit a grant scheduling the resources for the self-interference measurement by the UE. The UE may measure interference between a TRP of the UE that is configured for transmission and a TRP of the UE that is configured for reception using the scheduled resources. The UE may transmit a sidelink feedback message indicating resources that are available for sidelink full duplex communications by the UE based on the measured self-interference.

Abstract: According to some aspects, a wireless device may indicate to another device a receive configuration indicator (RCI) to indicate a receive spatial configuration of the wireless device. For example, a first device may configure the first device to receive, from a second device, a signal using a first receive spatial configuration of the first device that corresponds to a first transmit spatial configuration of the second device. The first device may further determine a RCI to indicate the first receive spatial configuration of the first device, and may transmit the RCI to the second device.

An example method includes receiving one or more signals comprising sidelink control information (SCI) at multiple TRPs of the sidelink device, the SCI indicating a resource reservation. The example method further includes decoding the SCI based on the one or more signals measuring a reference signal received power (RSRP) associated with the SCI at each of the multiple TRPs. The example method further includes. The example method further includes determining available resources for sidelink transmission for a subset of one or more of the multiple TRPs based on the RSRP.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network entity, an indication of a required minimum value for a time offset associated with a communication with the network entity, wherein the required minimum value for the time offset is associated with communicating with the network entity via an assisting node. The UE may receive, from the network entity, an indication of an offset value for the time offset based at least in part on the required minimum value for the time offset. The UE may communicate with the network entity via the assisting node in accordance with the offset value. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, at a second protocol layer of the UE and from a first protocol layer of the UE, the second protocol layer being lower than the first protocol layer, an indication of one or more quality of service parameters associated with a data packet to be transmitted by the UE. The UE may identify, from the one or more quality of service parameters, directional coverage information associated with the data packet, the directional coverage information indicative of one or more transmission directions in which the data packet is to be transmitted. The UE may transmit the data packet in accordance with at least the directional coverage information of the one or more quality of service parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, from a second UE, a first sidelink synchronization signal (SLSS) at a first transmission-reception point (TRP) and a second TRP different from the first TRP. The first UE may perform a first set of measurements on the first SLSS received at the first TRP and a second set of measurements on the first SLSS received at the second TRP. The first UE may then transmit, to a third UE, a second SLSS based at least in part on the first set of measurements, the second set of measurements, or both, satisfying one or more measurement thresholds.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for sidelink resource selection with AD usage awareness. A UE may receive, from one or more ANs, one or more resource usage schedules associated with one or more ADs in communication with the one or more ANs. The UE may combine the one or more resource usage schedules associated with the one or more ADs into a combined resource usage schedule. The usages may be associated with the combined resource usage schedule, which may be indicative of excluded resources for a transmission of the UE. The UE may transmit, based on the combined resource usage schedule, the transmission of the UE on a resource other than the excluded resources.

Abstract: Methods, apparatuses, and computer-readable storage medium for SL communications are provided. An example method may include transmitting, to one or more UEs, an SL transmission in a first direction using a first precoder. The example method may further include retransmitting, to the one or more UEs based on a configured maximum number of directional retransmissions and without allocating additional processes and memory for the packet, the SL transmission in one or more directions different from the first direction using one or more precoders different from the first precoder based on a SL retransmission configuration.
