29 Claims

13. A road side unit (RSU) for wireless communications, comprising:

a memory configured to store instructions; and

a processor communicatively coupled with the memory, the processor configured to execute the instructions to:

receive, at the RSU, a scheduling request for resources directly from a first user equipment (UE) for side-link communication with a second UE;

determine, at the RSU, at least one characteristic associated with the scheduling request, the at least one characteristic associated with the scheduling request includes latency requirements of the first UE for transmitting directly from the first UE to the second UE via side-link communication, the determining comprises modifying RSU scheduling frame structure in response to the latency requirements of the first UE satisfying a latency threshold;

allocate, at the RSU, resources in a resource pool to the first UE for the side-link communication with the second UE based on determining the at least one characteristic associated with the scheduling request; and

transmit, directly from the RSU to the first UE using the modified RSU scheduling frame structure, a scheduling grant identifying the allocated resources, wherein the scheduling grant indicates to the first UE the allocated resources in the resource pool that the first UE is to utilize for transmissions of packets for side-link communication directly from the first UE to the second UE.
