Embodiment 1
[0039] Based on the network architecture of D2D clustering, the present invention proposes a D2D inter-cluster equalization method, and the mathematical model adopted is as follows:
[0040] Suppose there are N CPE terminals U={u within the coverage of ENB 0 1 , u 2 ,...u N}, can form P clusters Ω={Ω 1 ,Ω 2 ,…Ω P},Satisfy:
[0041]
[0042] Cluster members between different clusters are independent (non-overlapping), that is, no CPE belongs to two or more clusters. Definition||Ω k || is cluster Ω k The total number of inner CPE, including ||Ω k || - 1 cluster member and 1 cluster head.
[0043] order h 0-i for The LTE channel status (signal-to-noise ratio or received power) of the currently connected ENB. order h i-j for and Wi-Fi channel status. Define the channel state threshold as h LTE and h Wi-Fi , if and only if the channel state is greater than the threshold (h 0-i ≥ h LTE , h i-j ≥ h Wi-Fi ), the channel is connectable, that is, the QoS inde...
