Title:
METHOD AND APPARATUS FOR ALLOCATING RESOURCES FOR MULTIPLE DEVICE-TO-DEVICE COMMUNICATIONS
Document Type and Number:
WIPO Patent Application WO/2014/170750
Kind Code:
A3
Abstract:
The invention provides a scheme to allocate resources in a communication system so as to accommodate multiple simultaneous D2D communications. Firstly an eNB sends a predetermined neighbor distance to all of D2D UEs in a cell; the respective D2D UEs determines their respective neighbor information based upon the received predetermined neighbor distance and send their respective neighbor information to the eNB; the eNB determines respective neighbor information of all of D2D pairs according to the received respective neighbor information from all the D2D UEs; then a receiving D2D UE in a D2D pair determines its value of tolerant interference degree and sends the determined value to the eNB; and the eNB takes the received value of tolerant interference degree of the receiving D2D UE as a value of tolerant interference degree of the D2D pair to which the receiving D2D UE belongs; and finally the eNB divides all the D2D pairs into several groups according to the respective neighbor information and values of tolerant interference degree of all the D2D pairs and based upon a greedy algorithm and allocates a different resource for each of the groups, and then notifies each of the D2D pairs a resource allocated for the each D2D pair.
