Methods and apparatus for resource collision avoidance in vehicle to vehicle communication

An apparatus of a first vehicle user equipment (UE) for collision avoidance using channel sensing in a wireless communication network, the apparatus comprising:

• a transceiver configured to receive a set of scheduling assignment (SA) information that is allocated to a set of second vehicle UEs in the wireless communication network;
• and
• at least one processor configured to:
• decode the set of SA information each of which includes SA information to each of the set of second vehicle UEs;
• perform energy sensing operation for resources to be used by each of the set of second vehicle UEs to determine additional potential SA transmission and data transmission from the set of second vehicle UEs over the resources;
• determine available resources for the data transmission from the first vehicle UE based on the performed energy sensing and SA sensing;
• and
• skip a channel sensing operation on at least one subframe that is used for the data transmission from the first vehicle UE based on a result of the determination of available resources, wherein if the at least one subframe is determined as a subframe m that is skipped for sensing by the first vehicle UE, a resource selection in subframes m to m+k*Pmin is avoided until the channel sensing operation is performed in subframe m+k*Pmin, wherein k is an integer and k>0, and Pmin is set to 100, and
• wherein the transceiver is further configured to transmit data among resources identified as unused in next transmissions from second vehicle UEs.
