Resource access in device to device communication

One or more non-transitory, computer-readable media (NTCRM) having instructions that, when executed by one or more processors of an access node (AN), cause the AN to:

• generate a configuration message with an information element that is to associate a priority with a pool of transmission resources to be used by a user equipment (UE) for sidelink communications;
• cause a physical layer of a protocol stack of the AN to transmit a downlink communication to the UE with the configuration message;
• receive, from the UE, information on status of one or more buffers that respectively corresponds to one or more priority levels;
• generate scheduling information to schedule a sidelink communication of the UE based on the status of the one or more buffers;
• and
• transmit, to the UE, an indication of the schedule.

A processor for a user equipment (UE) in a communications network, the processor comprising:

• circuitry to execute one or more instructions that, when executed, cause the processor to perform operations comprising:
• receiving, from an access node in the communications network, a configuration message with an information element including information associating a priority with a pool of transmission resources used by the UE for sidelink communications;
• determining status of one or more buffers that correspond to one or more priority levels;
• transmitting, to the access node, information on the status of the one or more buffers;
• and
• receive, from the access node, scheduling information to schedule a sidelink communication of the UE, the scheduling information generated based on the status of the one or more buffers.
