Distributed user location awareness cell closing method for LTE-A cellular network

Abstract

The invention discloses a distributed user location awareness cell closing method for an LTE-A cellular network, and belongs to the field of LTE-A downlink cooperative communication energy resource management in wireless communication. The distributed user location awareness cell closing method for the LTE-A cellular network is characterized in that cells which are small in number of users and low in utilization rate can be closed preferentially according to the number of users in peripheral communication cells, and thus the closing probability of all the cells with the low utilization rate can be improved. According to the distribution of the users in the communication cells, the optional adjacent base station range for receiving all transfer users in one cell is decreased, and therefore the algorithm complexity caused by the adoption of a minimax principle is reduced. The distributed user location awareness cell closing method for the LTE-A cellular network has the advantages that under the condition that the communication quality of the users is guaranteed, the user number threshold value participating in cell closing judgment can be adjusted dynamically according to the number of the users in the peripheral cells, the cell closing number is increased, and more energy can be saved; combined with the positions of the users in the cells, the search scope of an optimal receiving set is decreased, and hence the algorithm complexity is lowered.

Description

technical field [0001] The invention relates to a method for closing a distributed cell based on a user location, and belongs to the related field of energy resource management of LTE-A downlink cooperative communication in wireless communication. Background technique [0002] After decades of rapid development, driven by the ever-increasing demand for data traffic, Information and Communication Technology (ICT) is developing towards a more performance-oriented direction, and related energy consumption is also increasing. Recently, energy consumption has been promoted as an important topic and widely discussed after realizing the fact that the energy consumption of the ICT industry accounts for 3% of global energy consumption, and the emission of greenhouse gases accounts for 2-4% of global emissions , and the energy consumption of the ICT industry is increasing at a rate of 15-20% per year, doubling every five years. In traditional wireless cellular networks, the energy co...
