Embodiment Construction
[0032] The present invention will be further described with reference to the accompanying drawings. Such as figure 1 As shown, the present invention is a resource allocation method for D2D communication in a long-term evolution system, which includes a mutual communication device that directly communicates, and users at both ends of the communication device. The method includes the following steps:
[0033] (1) One end user holding the communication device sends a discovery signal of the mutual communication device to the base station, wherein the discovery signal includes the temporary identification of the wireless network within the range of the one end user;
[0034] (2) The base station performs geographic location detection, wherein the base station obtains the geographic location information of the user at the end according to base station positioning or GPS or assisted A-GPS, and at the same time feeds back a record to the user at the end and the end A list of users in the...
