[0018] like figure 1 As shown, in a single cell environment, there is one base station, M cellular users, and N D2D pairs, and all users are evenly distributed in the cell. Assuming that all D2D pairs have completed the device discovery and pairing process, the base station can detect all D2D pairs. Related Channel State Information (CSI). In the LTE system, the system bandwidth is divided into resource blocks of equal size, ...
