Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to one or more other UEs, one or more sidelink reference signal block (S-RSB) bursts in a sidelink beam measurement gap (SBMG) based at least in part on one or more SBMG configurations. The UE may receive, from the one or more other UEs, one or more beam reports or beam measurement reports based at least in part on the one or more S-RSB bursts and the one or more SBMG configurations. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station may schedule a multi-transmission reception point (mTRP) UE for concurrent uplink and sidelink transmissions based on interference measure. For example, abase station may determine an amount of interference associated with resources used for sidelink communications between the mTRP UE and a second UE. Based on the determined amount of interference, the base station may transmit a resource grant to the mTRP UE indicating a first set of resource for transmitting one or more uplink messages to the base station and a second set of resources for transmitting one or more sidelink messages to the second UE, where the first set of resources and the second set of resources at least partially overlap in time.

Abstract: Certain aspects of the present disclosure provide techniques for facilitating sidelink (LS) cross-link interference (CLI) measurements within a wireless communication network. A method that may be performed by a second UE includes receiving a sidelink (SL) cross-link interference (CLI) configuration from a second base station indicating resources for performing the SL CLI measurements, performing the SL CLI measurements on the resources indicated in the SL CLI configuration, and transmitting a report to the second base station indicating the SL CLI measurements.

Abstract: The apparatus may be a base station configured to receive a request for resources for transmission of a first SL communication; to determine one or more destination IDs associated with the transmission of the first SL communication; to determine, based on the one or more determined destination IDs, a set of resources that support FD SL communications by the requesting UE; and to transmit, based on the determined set of resources, a resource grant to the requesting UE for transmission of the first SL communication. The apparatus may be a UE configured to transmit a request for resources for transmission of a SL communication and an indication of at least one destination ID associated with at least one SL communication received at the UE to the base station; and to receive, from the base station, a SL resource grant based on the transmitted request and indication.

Abstract: A first UE transmits, on a first unicast link to a second UE, a first RS from a first TRP of the first UE. The first UE receives, based on the first RS transmitted, a first channel measurement for the first unicast link from the second UE and a first interference measurement for a second unicast link from a third UE. The first UE transmits, on the second unicast link with the third UE, a second RS from a second TRP of the first UE. The first UE receives, based on the second RS transmitted, a second channel measurement for the second unicast link from the third UE and a second interference measurement for the first unicast link from the second UE. The first UE applies SDM for the first unicast link and the second unicast link based on the received channel and interference measurements.

Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A first user equipment (UE) may transmit, to a second UE, sidelink control information (SCI) including an indication of resources and a number of spatial layers for a sidelink transmission. The first UE may perform spatial domain multiplexing (SDM) between the spatial layers. The first UE may transmit a first data packet associated with the first spatial layer from a first transmission reception point (TRP) and may transmit a second data packet associated with a second spatial layer from a second TRP. In some examples, the first UE may include a first and second stage of the SCI, such that the first SCI corresponds to shared information for all spatial layers and the second stage of the SCI corresponds to separate information for each spatial layer.

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.
