Problems solved by technology

The frequency bands used by the existing 4G network mobile communication system and the next-generation mobile communication system are all high-frequency bands around 2GHz. This high-frequency wireless signal has a very strong penetrating ability, and the transmission energy loss is also very large, resulting in a significant attenuation of indoor signals. , even in some closed environments, the coverage will be weak, and even the coverage "hole" phenomenon
Under such circumstances, only relying on the macro base station can no longer meet the communication needs of indoor users.

Abstract

The invention relates to the field of mobile communication, in particular to an intensive small cellular network resource allocation method based on energy efficiency. The method includes the following steps: determining an optimal cell choice based on load balancing; determining a channel allocation scheme according to the optimal cell choice; and optimizing the energy efficiency of the network to determine an optimal power allocation scheme according to the channel allocation scheme. The optimal cell choice controls the probability that a user accesses a base station through the modeling ofload balancing under the premise of ensuring the transmission requirements of the user, so that load balancing is realized, and the energy efficiency of the network is improved. Based on a determinedload balancing scheme, reasonable channel allocation and power allocation schemes are achieved by optimizing the energy efficiency of the network.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to an energy efficiency-based dense small cell network resource allocation method. Background technique [0002] With the widespread application of the Internet and the popularization of mobile smart terminals, people's demand for mobile data services is increasing day by day. Now people are used to and rely on the ubiquitous and all-time wireless network. The frequency bands used by the existing 4G network mobile communication system and the next-generation mobile communication system are all high-frequency bands around 2GHz. This high-frequency wireless signal has a very strong penetrating ability, and the transmission energy loss is also very large, resulting in a significant attenuation of indoor signals. , Even in some closed environments, the coverage will be weak, and even the coverage "hole" phenomenon. In such a situation, only relying on the macro base station can no l...
