Abstract

The invention discloses a multi-station and community-sharing transmitted power control method and device. The multi-station and community-sharing transmitted power control method comprises the steps of acquiring power control parameter when a mobile terminal switches to a target RRU position; calculating power-control step length based on the power control parameter; determining power-control level based on the power-control step length; sending the power control level so that an end can conduct transmitted power control based on the power control level. The multi-station and community-sharing transmitted power control method and device are advantageous in that when a BSS detects that the mobile terminal switches to the target RRU position group, the power-control step length and corresponding power-control level can be calculated through acquiring the power-control parameter; the uplink or downlink power control when the mobile terminal moves to the RRU position group can be realized; energy consumption of base stations and the mobile terminal can be reduced, and the uplink and downlink interference of network can be reduced.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a transmission power control method and device under a multi-site common cell. Background technique [0002] Shared cell refers to setting multiple location groups RRU (Radio Remote Unit, radio remote module) of different physical sites as a logical cell, so as to improve the signal quality of the coverage area and reduce the number of handovers in scenarios such as high-speed rail coverage and tunnel coverage , to improve user experience. The cell parameters such as the physical configuration, the number of carriers, and the frequency point of each location group are the same, covering a certain area, and the continuous coverage area of ​​multiple adjacent location groups is the coverage area of ​​the multi-site shared cell. The multi-site shared cell is referred to as the RRU shared cell, and the RRU location group is a constituent element of the RRU share...
