  • Publication number: 20240107603
    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a first user equipment (UE) to establish a communication link with a base station and a sidelink communication link with a second UE using different transmission reception points associated with the first UE. The first UE may perform an interference measurement between downlink communications received on the communication link and sidelink communications transmitted on the sidelink communication link. The first UE may determine whether it is able to perform full-duplex operations on the communication link and the sidelink communication link based on the interference measurement and may transmit an indication of the capability of the first UE to the base station.

  • Publication number: 20240098657
    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.

  • Publication number: 20240040559
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from another UE, a coordination message that includes resource information (e.g., a preference status) for communication resources. The UE receiving the coordination message may determine a status of one or more resources based on the resource information, an intended recipient of the coordination message (e.g., based on a destination identifier of the coordination message), or a communication connection associated with the one or more resources. The status may indicate that a respective resource of the one or more resources is available, reserved, preferred, or non-preferred, or some combination thereof. In some examples, the one or more resources may be for a sidelink connection or a unicast connection. The receiving UE may utilize the determined status to select one or more resources for a sidelink transmission.
