Resource access in device to device communication
A wireless communication device is configured to perform resource access in device-to-device (D2D) communication. A user equipment (UE) is provided with processing hardware comprising application processing circuitry and baseband processing circuitry. The application processing circuitry assigns a per-packet priority to data packets in the application layer. The baseband processing circuitry maps the per-packet priority to a transmission priority in the physical layer and prioritizes access to a wireless resource pool depending upon the transmission priority. A UE having the application processing circuitry and baseband processing circuitry is also provided. A computer program product is also provided. An evolved Node B (eNodeB) allocates a resource quota to a UE based upon priority information from the UE corresponding to a D2D communication to be transmitted by the UE. Other embodiments may be described and claimed.
1. One or more non-transitory, computer-readable media (NTCRM) having instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
process a configuration message received from an access node to identify an information element that is to associate a priority with a pool of transmission resources to be used by the UE for sidelink communications, wherein the priority is a first priority; and
cause a physical layer of a protocol stack of the UE to transmit a sidelink communication in the pool of transmission resources based on the priority, wherein to cause the physical layer to transmit the sidelink communications, the UE is to:
generate information associated with a second priority;
map the second priority to the first priority;
encode the sidelink communication with the information associated with the second priority; and
transmit the sidelink communication in the pool of transmission resources based on mapping of the second priority to the first priority.
2. The one or more NTCRM of claim 1 , wherein the instructions, when executed, further cause the UE to:
autonomously select the pool of transmission resources for transmission of the sidelink communications.
3. The one or more NTCRM of claim 1 , wherein the pool of transmission resources is a physical sidelink shared channel pool and the sidelink communications is to include data to be transmitted to another UE.
4. The one or more NTCRM of claim 1 , wherein the pool of transmission resources is a physical sidelink control channel pool and the sidelink communications is to include sidelink control information to be transmitted to another UE.
5. The one or more NTCRM of claim 1 , wherein the information element is to associate the priority with a sidelink transmission period in which a plurality of pools of transmission resources, including the pool of transmission resources, are located.
6. The one or more NTCRM of claim 1 , wherein the pool of transmission resources include resources having a time-resource pattern of transmission (T-RPT) pattern.
7. The one or more NTCRM of claim 1 , wherein the pool of transmission resources include resources having a subset of time-resource pattern of transmission (T-RPT) patterns within one or more physical sidelink shared channel pools.
8. The one or more NTCRM of claim 1 , wherein the pool of transmission resources include sidelink control information resources within a physical sidelink control channel pool.
9. The one or more NTCRM of claim 1 , wherein the priority is selected from eight priority values.
10. 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.
11. The one or more NTCRM of claim 10 , wherein the instructions, when executed, further cause the AN to: select the priority from eight priority values.
12. The one or more NTCRM of claim 10 , wherein the pool of transmission resources is a physical sidelink shared channel pool and the sidelink communications is to include data to be transmitted to another UE.
13. The one or more NTCRM of claim 10 , wherein the pool of transmission resources is a physical sidelink control channel pool and the sidelink communications is to include sidelink control information to be transmitted to another UE.
14. The one or more NTCRM of claim 10 , wherein the pool of transmission resources include sidelink control information resources within a physical sidelink control channel pool.
15. 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:

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.
16. The processor of claim 15 , wherein the pool of transmission resources includes a physical sidelink control channel pool and the sidelink communications is to include sidelink control information to be transmitted to another UE.
