Embodiment 1
[0111] In a relay network with 1 base station eNB, 2 relay stations RN1, RN2, and 3 users UE1, UE2, UE3, user 1 and user 2 are served by RN1 and RN2 respectively, and UE3 is directly served by the base station. The system can allocate resources to 5 RBs, denoted as RB1, RB2, RB3, RB4, RB5, and the average obtained resource quantization value of user i is known as T i . In the submission stage, the quantized value of the channel condition of user i on RBk is SINR2 U i,k , have exceeded the basic threshold THb2; in the delivery phase, the quantized channel status value of user i on RBk is SINR1 U i,k , the channel status quantization value of relay station j on the RBk in the transmission phase is SINR1 R j,k , have exceeded the basic threshold THb1.
[0112] 1. Firstly, the resource allocation in the submission stage is carried out. For RB1, the priorities of the three users are respectively obtained according to the following methods:
