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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of available resources for a sidelink transmission by performing an iterative resource exclusion procedure, wherein performing the iterative resource exclusion procedure comprises determining, for an iteration, a set of potentially available resources that is based at least in part on a primary resource set and an auxiliary resource set, wherein the auxiliary resource set comprises a first resource of a set of sidelink resources in a resource selection window having a corresponding reference signal received power (RSRP) measurement that is less than an RSRP measurement corresponding to a second resource, and wherein the primary resource set includes the second resource. The UE may transmit the sidelink transmission using the set of available resources and at least one transmitter-receiver point of the UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for are described. A user equipment (UE) may transmit, via a first transmission-reception point (TRP), a first sidelink control information (SCI) scheduling a first sidelink transmission from the UE, the first SCI including an indication that a first hybrid automatic repeat request (HARQ) process associated with the first sidelink transmission is enabled. The UE may transmit, via a second TRP different from the first TRP, a second SCI scheduling a second sidelink transmission from the UE, the second SCI including an indication that a second HARQ process associated with the second sidelink transmission is disabled. The UE may transmit the first sidelink transmission and the second sidelink transmission via the first TRP and the second TRP, respectively, based on transmitting the first and second SCI. The UE may monitor, via the first TRP, for a feedback message based on transmitting the first sidelink transmission.
