CONTROL OVERHEAD REDUCTION IN SIDELINK NETWORK

Abstract:

Methods, systems, and devices for wireless communications are described. Multiple user equipments (UEs) may communicate as part of a sidelink communications system. The UEs may identify a frame for a sidelink connection. The frame may include a control portion and a data portion. One UE of a pair of UEs may receive a data signal from the other UE of the pair, and the data signal may be received in the data portion of the first instance of the frame and in the control portion of a second instance of the frame. Another pair of UEs may attempt to reserve a subsequent data portion by transmitting a request signal in the control portion in the second instance of the frame, and the second pair of UEs may receive a suppression signal from the first pair of UEs indicating ongoing data transmission by the first pair of UEs.
