  • Publication number: 20220417905
    Abstract: Methods, systems, and devices for wireless communications are described that support sidelink cancellation for out of coverage user equipment. Described techniques provide for signaling of cancellation indications to a user equipment (UE) or a group of UEs to refrain from performing sidelink communications on a set of resources. A base station may transmit a cancellation indication to one or more sidelink UEs via an access link that indicates that an allocation of one or more resources for sidelink communications has been canceled. A first UE may receive the cancellation indication from the base station via the access link and transmit a sidelink communication to one or more other UEs that indicates the canceled resource allocation. Based on the sidelink communication of the cancellation indication from the first UE, the one or more other UEs may refrain from transmitting using the canceled resources.

  • Patent number: 11540303
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may alter, or otherwise cancel, a sidelink communication as a result of a cancelation indicator (CI) corresponding to a different UE to support automatic gain control (AGC) calibration. The UE may determine to cancel or alter sidelink resources that at least partially overlap in time and are adjacent to, yet non-overlapping, in frequency to a high priority transmission. In some implementations, the UE may cancel the sidelink communication from an earliest overlapping symbol to the end of a slot. In other implementations, the UE may cancel a portion of the sidelink communication and resume sidelink communications within the same slot. Additionally or alternatively, the UE may utilize one or more reference signals or symbols to enable AGC recalibration during the slot.
