[0067] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0068] The present invention is a scheme for estimating the utilization rate of BBU resources in the BBU pool, combined with the aggregation and removal algorithm to determine the switching of the BBU state, the state switching of the BBU is dynamically adjusted according to the transmission power utilization rate and the traffic utilization rate, and is summarized for 3 steps:
[0069] First, the transmission power between the RRH and MUE, the rate requirement of each MUE, the number of MUEs, the precoding matrix, the RRH bandwidth, the signal-to-interference-plus-noise ratio and other factors are considered, and the transmission power utilization rate and traffic usage.
[0070] Then, in the BBU pool of the C-RAN, the resource usage rate of each specific BBU is calculated according to the transmission power usage rate and the traffic usage rate. On this b...
