Sidelink communication resource set configuration and management

A method of wireless communication at a first user equipment (UE), the method comprising:

• negotiating with a second UE to select a first communication resource set (ComReSet) from a plurality of ComReSets for sidelink communication, each of the plurality of ComReSets having a corresponding periodicity of one or more hyper-frames;
• and
• communicating with the second UE using the first ComReSet using a frame timing synchronized with the corresponding periodicity of the first ComReSet;
• wherein the plurality of ComReSets comprise the first ComReSet and a second ComReSet;
• a first periodicity of the first ComReSet is different from a second periodicity of the second ComReSet;
• the first ComReSet repeats according to the first periodicity;
• and
• the second ComReSet repeats according to the second periodicity that is different in duration from the first periodicity in terms of a number of hyper-frames.

A first user equipment (UE) for wireless communication comprising:

• a transceiver configured to communicate with a second UE:
• a memory;
• and
• a processor operatively coupled to the memory and the transceiver,
• wherein the processor and the memory are configured to:
• negotiate with the second UE to select a first communication resource set (ComReSet) from a plurality of ComReSets for sidelink communication, each of the plurality of ComReSets having a corresponding periodicity of one or more frames;
• and
• transmit a message in a first time slot of the first ComReSet to reserve a second time slot of the first ComReSet in a same frame;
• transmit a message in the first time slot of the first ComReSet to reserve a third time slot of the first ComReSet in a different frame;
• sense the first ComReSet for a predetermined time duration to select available resources of the first ComReSet;
• communicate with the second UE using the selected available resources of the first ComReSet for sidelink communication;
• and
• receive control information from a scheduling entity, the control information configuring the predetermined time duration.
