Energy-saving wireless resource management method in intensively-deployed family base station network

Abstract

The invention relates to a distributed-type energy-saving wireless resource management method in an intensively-deployed family base station network, wherein power and information channels are jointly distributed. In order to avoid interference of the intensively-deployed family base station network on a macro base station, different frequency bands are used by the family base station and the macro base station. According to the method, information channel distribution and power control are achieved through two steps: firstly, the gain of each user for each information channel and the born same-layer interference are acquired by the family base station, the interference gain ratio is worked out by the family base station when each user occupies each information channel, and an information channel is distributed to a user with the minimum interference gain ratio; secondly, power distribution is that power consumption of user sides and the same-layer interference in the whole family base station network are taken into consideration through a non-cooperative game method, power distribution of the whole network reaches a Nash equilibrium state through non-cooperative games, and therefore energy efficiency of all users reaches the highest, and the energy-saving goal of the whole network is achieved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a wireless resource management technology for improving energy efficiency of all users by jointly allocating uplink channel and power in a densely deployed home base station network. Background technique [0002] The fourth-generation mobile communication technology is being gradually promoted for commercial use. Due to the high frequency band it uses, the penetration loss to walls is relatively large. Therefore, the coverage of macro base station signals in indoor environments is not ideal. At the same time, statistics show that 70% of voice services and 90% of data services occur indoors, and it is not enough to rely solely on macro base station signals to provide indoor users with high-quality services. Therefore, femtocell technology has emerged as the times require. The femtocell is a plug-and-play low-power small base station deployed by users. It is ma...

[0002] The fourth-generation mobile communication technology is gradually promoted for commercial use. Due to the high frequency band it uses, the penetration loss to the wall is relatively large. Therefore, the coverage of the macro base station signal for the indoor environment is not ideal.

[0004] At the same time, in residential areas, shopping malls, office buildings and other dense deployment areas of home base stations, the same frequency interference between home base stations is serious, which greatly reduces the overall capacity of the network

Due to differences in deployment and management methods, the traditional centralized wireless resource management method is not applicable in the femtocell network scenario. How to effectively manage wireless resources to meet user service quality requirements while reducing terminal energy consumption and improving home The energy efficiency of base station network users becomes a new challenge in the future design of femtocell network
