Embodiment Construction
[0085] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0086] Such as figure 1 As shown, it is a model of a possible transfer path of the UE during the dormancy process of the base station of the present invention.
[0087] The heterogeneous network includes a macro base station and n evenly distributed macro users, n≤200, and N small base stations are distributed in the coverage edge area of the macro base station, N≥5, randomly distributed within the coverage area of any small base station f l small base station users, where f=1,...,N, l≥5, macro base station has M available physical resource blocks (physical resource blocks, PRB), M≤200, where F f PRBs are allocated to N small base stations for multiplexing, F f =N, the number of small base station users using the same frequency band PRB(r) for communication at the same time is F r , where 1≤r≤M, F r ≥2.
