  • Scheduling request procedure for D2D communication
    Patent number: 11723031
    Abstract: The present invention relates to a D2D capable a communication method and to a transmitting user equipment, which transmits data to a receiving user equipment over a direct link data channel, uses the services of the eNodeB in order to have resources allocated for transmitting said data. To this end the UE sends to the eNB scheduling information using resources of a subframe dedicated for standard uplink communication through the eNodeB, rather than using resources on the subframe dedicated to D2D data transmission. In order to allow the eNB to distinguish whether the received scheduling request is for allocating resources for transmitting data over the direct link channel or over the eNB, UE may send along with the scheduling information also identification information associated to the scheduling information.
