METHOD AND APPARATUS FOR IMPROVING DEVICE TO DEVICE (D2D) COMMUNICATION IN A WIRELESS COMMUNICATION SYSTEM

摘要

Methods and apparatuses for improving device to device (D2D) communication are disclosed herein. One method includes communicating, by a user equipment (UE), with a device via the D2D communication. The method further includes triggering, by the UE, a first power headroom report (PHR) to indicate a power status of the D2D. The method also provides for triggering and transmitting, by the UE, a Scheduling Request (SR) to ask for radio resources from a network for scheduling if the UE has no available resources to transmit the first PHR. The method further includes triggering, by the UE, a second PHR to indicate a power status of a transmission path from the UE to the network and not triggering and transmitting the SR to ask for radio resources from the network for scheduling if the UE has no available resource to transmit the second PHR.

1. A method for improving device to device (D2D) communication, the method comprising:
communicating, by a user equipment (UE), with a device via the D2D communication; triggering, by the UE, a first power headroom report (PHR) to indicate a power status of the D2D communication; triggering and transmitting, by the UE, a Scheduling Request (SR) to ask for radio resources from a network for scheduling if the UE has no available resources to transmit the first PHR; and triggering, by the UE, a second PHR to indicate a power status of a transmission path from the UE to the network and not triggering and transmitting the SR to ask for radio resources from the network for scheduling if the UE has no available resource to transmit the second PHR.
