Abstract
A method for a device-to-device (D2D) communication includes determining, by the a device, availability of a D2D buffer status report (BSR) resource. The method also includes in response to determining that the D2D BSR is not available, generating, by the device, a D2D scheduling request (D2D-SR) message in accordance with D2D-SR configuration information and transmitting, by the device, the D2D-SR message in a D2D-SR resource when the D2D-SR resource is available.
Claims24
A method for device-to-device (D2D) communication, the method comprising:
- determining, by a device, an availability of a D2D buffer status report (BSR) resource and that the device also has a cellular signal to transmit in a subframe corresponding to a D2D-scheduling request (D2D-SR) resource;
- and
- in response to determining that the D2D BSR resource is unavailable,
- generating, by the device, a D2D-SR message in accordance with D2D-SR configuration information, the D2D-SR message requesting allocation of an uplink resource for transmission of a D2D BSR message,
- prioritizing, by the device, in accordance with a prioritizing rule, the cellular signal and the D2D-SR message in the subframe corresponding to the D2D-SR resource, and
- transmitting, by the device, the D2D-SR message in accordance with the prioritizing.
A device for device-to-device (D2D) communication, comprising:
- a processor configured to:
- determine an availability of a D2D buffer status report (BSR) resource and that the device also has a cellular signal to transmit in a subframe corresponding to a D2D-scheduling request (D2D-SR) resource;
- and
- in response to determining that the D2D BSR resource is unavailable:
- generate a D2D-SR message in accordance with D2D-SR configuration information, wherein the D2D-SR message requests allocation of an uplink resource for transmission of a D2D BSR message, and
- prioritize, in accordance with a prioritizing rule, the cellular signal and the D2D-SR message in the subframe corresponding to the D2D-SR resource;
- and
- a transmitter operatively coupled to the processor and configured to transmit the D2D-SR message in accordance with the prioritizing.
A device for device-to-device (D2D) communication, comprising:
- a non-transitory memory storage comprising instructions;
- and
- a processor in communication with the non-transitory memory storage, wherein the processor executes the instructions to cause the device to:
- determine an availability of a D2D buffer status report (BSR) resource and that the device also has a cellular signal to transmit in a subframe corresponding to a D2D-scheduling request (D2D-SR) resource;
- in response to determining that the D2D BSR resource is unavailable:
- generate a D2D-SR message in accordance with D2D-SR configuration information, wherein the D2D-SR message requests allocation of an uplink resource for transmission of a D2D BSR message, and
- prioritize, in accordance with a prioritizing rule, the cellular signal and the D2D-SR message in the subframe corresponding to the D2D-SR resource;
- and
- transmit the D2D-SR message in accordance with the prioritizing.
