Title: METHOD AND APPARATUS FOR SENDING AND RECEIVING DATA
Abstract:
Disclosed are a method and apparatus for sending and receiving data, relating to the technical field of wireless communications. The method comprises: a control node receives a transmission request sent by a source terminal, determines, according to a terminal identifier of the source terminal and a terminal identifier of a destination terminal, that the channel quality of a D2D link directly connecting the source terminal with the destination terminal does not satisfy a preset quality condition, determines a first D2D path with channel quality satisfying the preset quality condition from the source terminal to the destination terminal, the first D2D path comprising at least one transit terminal that is any multi-hop D2D terminal in the first D2D path other than the source terminal and the destination terminal, and sends path information of the first D2D path to the terminals in the first D2D path other than the destination terminal. The control node comprises: a first receiving module, a first determining module, a second determining module, and a first sending module. The present invention can improve the communication quality when the source terminal sends D2D data to the destination terminal.
