Abstract

Embodiments of the present invention provide a C-RAN network planning method and device. The method includes obtaining the overlapping coverage of each RRU in the RRU set and other RRUs; marking other RRUs whose overlapping coverage is higher than a preset coverage threshold as adjacent RRUs; selecting an RRU from the RRU set as the main RRU; if the main RRU Between the RRU and the adjacent RRUs in the RRU set, and between any two adjacent RRUs that meet the preset distance threshold, they are combined into a sub-cluster; the RRUs in the sub-cluster are removed from the RRU set, and then from the RRU set Select the next RRU from the remaining RRUs as the primary RRU until the remaining RRUs in the RRU set are not adjacent RRUs of other RRUs. The embodiment of the present invention obtains the adjacency relationship of each RRU in the RRU set, and then combines the mutual Dividing the RRUs in the RRU set into multiple sub-clusters is helpful for BBU planning, thereby reducing the anti-interference effect between RRUs and improving the spectrum efficiency function.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wireless communication, and in particular to a C-RAN network planning method and device. Background technique [0002] The centralized radio access network (Centralized Radio Access Network, C-RAN) is a new radio access network framework proposed according to the current network conditions and the trend of technological progress. C-RAN is a green wireless access network architecture (Clean system) based on centralized processing (Centralized Processing), collaborative radio (Collaborative Radio) and real-time cloud computing architecture (Real-time CloudInfrastructure). Its essence is to achieve low cost, high bandwidth and flexible operation by reducing the number of base station equipment rooms, reducing energy consumption, adopting collaborative and virtualization technologies, realizing resource sharing and dynamic scheduling, and improving spectrum efficiency. The network a...
