Problems solved by technology

However, in reality, communication has high requirements on delay, and because the complexity of allocation between RRH and BBU increases exponentially, when the number of RRH and BBU is dozens, the power of two is already astronomical. The numbers are gone, so the brute force search algorithm is not feasible

Abstract

The invention discloses a resource scheduling optimization method for a remote radio head and a baseband processing unit, which improves the existing RRH and BBU resource allocation algorithm, and applies the hybrid chemical reaction optimization algorithm to the scheduling allocation between the RRH and the BBU, not only It can reduce the allocated power consumption of RRH and BBU, and can also reduce the operator's investment in power resources in C-RAN, so as to achieve the effect of environmental protection and energy saving.

Description

technical field [0001] The invention belongs to the technical field of cloud wireless access networks, and in particular relates to the design of a resource scheduling optimization method for a remote radio head and a baseband processing unit. Background technique [0002] As a new cloud architecture, C-RAN (Cloud-Radio Access Network, Cloud-Radio Access Network) is introduced to become the infrastructure of future mobile network operators. Using the method of function separation, the traditional base station is divided into two parts: (1) the base band processing unit (Base Band Unit, BBU), which performs layer-shift digital processing of the base band signal and all upper-layer functions and interfaces with the backhaul network, and ( 2) The remote radio head (Remote Radio Head, RRH), which is connected to the front / rear end of the antenna, and performs the remaining layer 1 functions, that is, the baseband signal of the digital-to-analog conversion / analog-to-digital conve...
