Problems solved by technology

Due to the high cost of high-power power amplifiers, the implementation cost of ultra-distance coverage applications is greatly increased; on the other hand, the overall power efficiency of current ultra-distance base stations is very low (about 10%), so the higher the output power The ultra-distance base station will cause higher power waste

Embodiment Construction

[0037] In the wireless communication system, in order to reduce the waste of electric energy when the base station (hereinafter referred to as the ultra-distance base station) that adopts the dual time slot technology to realize the long-distance coverage is working, in this embodiment, when the mobile terminal initially accesses the wireless communication system , the ultra-distance base station receives the access request sent by the mobile terminal, measures the distance between the current location of the mobile terminal and the base station, and allocates a preset first carrier or second carrier for the mobile terminal according to the distance. During the continuous communication process of the terminal, the base station measures the distance between the current location of the mobile terminal and the base station, and confirms the home area of ​​the mobile terminal's current location according to the distance, and determines the current home area of ​​the mobile terminal ...

Abstract

The invention discloses a multi-carrier power sharing method. The method comprises the following steps: a base station receives an access request sent by a mobile terminal; the base station measures distance between present location of the mobile terminal and the base station; and the base station allocates a first carrier wave or a second carrier wave for the mobile terminal according to the distance, wherein, the base station uses the first carrier wave to perform inner cell signal coverage, and uses the second carrier wave to perform outer cell signal coverage. In such way, the method helpsto reduce maximum output power and power consumption of the base station to a certain extent while realizing super long-range coverage of the base station, thus saving electric energy of a system andlowering the system operation cost. The invention further discloses a corresponding base station and a communication system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for multi-carrier power sharing. Background technique [0002] With the rapid development of wireless communication network (for example, GSM network) technology, the competition among operators is increasingly fierce, and "signal coverage" has gradually become the most competitive advantage, so each operator needs to It is recommended to build wireless communication networks in areas with low traffic volume but high market potential. For example, set up base stations in special areas such as grasslands, offshore, Gobi, and deserts to obtain long-term economic benefits. However, the coverage of the wireless communication network will be limited by relevant regulations. For example, in the GSM relevant regulations, it is stipulated that the cell coverage radius of the base station in the GSM network cannot exceed 35 kilometers at most. However, for th...
