Abstract: Apparatus, methods, and computer program products for resource allocation for multi-TRP sidelink communication are provided. 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.

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: In various embodiments supporting directional security, a user equipment (UE) may receive from a network device a noise resource allocation including an indication of a noise direction and a noise parameter, generate a noise signal based at least in part on the noise parameter, and transmit the noise signal in the noise direction while transmitting a communication transmission signal in a different direction from the noise direction. In various embodiments, a network device may determine a geographic zone of interest, select one or more reconfigurable intelligent surfaces (RISs) associated with the geographic zone of interest, selecting one or more noise transmitting UEs, control the one or more noise transmitting UEs to transmit at least one noise signal, and control the one or more RISs to steer the at least one noise signal into the geographic zone of interest.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit, to a base station, a buffer status report for a first sidelink transmission to a device. The first UE may receive, from a second UE, sidelink control information scheduling the first UE for a time resource for a second sidelink transmission from the second UE, the sidelink control information including an indication of a serving cell identifier of the second UE. The first UE may detect a half-duplex scheduling conflict, or a possible half-duplex scheduling conflict, based on the serving cell identifier and transmit an indication of the conflict to a serving base station. The base station may then assign, or re-assign, resources for the first sidelink transmission to avoid the scheduling conflict.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from one or more additional UEs, one or more indicators corresponding to one or more resource reservations. Accordingly, the UE may transmit data, to a second UE, on a sidelink channel, with at least one resource reservation, of the one or more resource reservations, indicated within a control element transmitted with the data. For example, the control element may include a list or a bitmap indicating the at least one resource reservation. 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 select, from stored configuration information or a received indication, an inter-UE coordination scheme that is configured for a resource pool associated with the first UE. The UE may transmit, to a second UE, an indication of one or more of preferred sidelink resources or non-preferred sidelink resources for transmission from the second UE to the first UE, based at least in part on the inter-UE coordination scheme. Numerous other aspects are described.
