Sidelink cancellation for out of coverage user equipment

A method for wireless communications, comprising:

• receiving a sidelink communication from a first user equipment (UE) at a second UE, the sidelink communication including a notification of a canceled resource allocation from an access network entity that cancels one or more resources for sidelink communications between a plurality of sidelink UEs, wherein the plurality of sidelink UEs include the first UE and the second UE, and the second UE is out of coverage for communications with the access network entity;
• canceling, based at least in part on the notification, one or more sidelink communications with one or more of the plurality of sidelink UEs;
• and
• transmitting, to at least a third UE of the plurality of sidelink UEs that is out of coverage for communications with the access network entity, a sidelink message that indicates the canceled resource allocation.

An apparatus for wireless communications at a first user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from an access network entity, an indication of a canceled resource allocation that identifies at least a portion of a sidelink resource allocation for communications between the first UE and one or more other UEs is canceled, wherein the one or more other UEs include at least a second UE that is out of coverage for communications with the access network entity;
• and
• transmit, to at least the second UE, a sidelink communication that includes a notification of the canceled resource allocation, wherein the sidelink communication includes one or more of a distance from the access network entity that is associated with the canceled resource allocation, or an identification of the access network entity that provided the indication of the canceled resource allocation, for determination at the second UE of whether to cancel sidelink transmissions that use the canceled resource allocation.
