Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may reserve a set of sidelink resources for a first sidelink transmission. A detecting UE may identify a sidelink feedback channel collision arising from a first sidelink feedback transmission to a first UE and a second sidelink feedback transmission to a second UE sharing same feedback channel resources. The detecting UE may determine one or more UEs to transmit a sidelink feedback channel collision indication to, and transmit, the collision indication to the one or more UEs. The first UE may identify a collision involving the first sidelink feedback transmission associated with the first sidelink transmission and the second sidelink feedback transmission associated with a second sidelink transmission by the second UE. The first UE may determine to transmit or retransmit the first sidelink transmission based on the sidelink feedback channel collision being identified.

Abstract: Methods and devices for wireless communications are described. A first user equipment (UE) may establish a first sidelink connection with a second UE and a second sidelink connection with a third CE. The first UE may receive an indication of a first set of transmission resources for the second UE to use to transmit to the first UE. The first UE may transmit an indication of a second set of transmission resources for the second UE to use to transmit to the first UE, the second set of transmission resources identified by the first UE based at least in part on comparing signals received using the first transmission reception point with signals received using the second transmission reception point. The first UE may receive a data message from the second UE on the second set of transmission resources.

Abstract: Techniques for sidelink (SL) and uplink (UL) full duplex communication with multiple transmission and reception points (multi-TRP) may be performed. In an example, a user equipment (UE) may determine full duplex communication, including simultaneous reception of a SL communication from an SL UE via a first TRP of the UE and transmission of a UL transmission to a base station via a second TRP of the UE, is available. The UE may enable the full duplex communication. The UE may receive, from the SL UE, the SL communication via the first TRP. The UE may transmit, to the base station while simultaneously receiving the SL communication, the UL transmission via the second TRP.

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: Apparatus, methods, and computer program products for full-duplex determination are provided. An example method includes transmitting a Uu signal from the UE. The example method further includes performing a self-interference measurement (SIM) of the Uu signal for full-duplex reception at the UE using the sidelink interface.

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: 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.
