Embodiment Construction

[0093] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, and to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and understandable, the following describes the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings For further detailed explanation.

[0094] see figure 1 , is a flow chart of a transmission power control method under a multi-site shared cell according to an embodiment of the present invention.

[0095] This embodiment is applicable to a scenario where a mobile terminal is handed over to a target RRU location group under a multi-site shared cell, especially a scenario where a mobile terminal is handed over to a target RRU location group under a voice service. The transmission power control method may include:

Abstract

Disclosed are a multi-site cell transmit power control method and device. The multi-site cell transmit power control method comprises: acquiring a power-control parameter when a mobile terminal is handed over to a target RRU subsite; calculating a power-control step length according to the power-control parameter; determining a power-control level according to the power-control step length; and sending the power-control level, so that a peer end performs transmit power control according to the power-control level. In the embodiments of the present invention, when a BSS detects that a mobile terminal is handed over to a target RRU subsite, a power-control parameter is acquired, and a power-control step length and a corresponding power-control level are calculated; therefore, uplink and / or downlink power control when the mobile terminal moves to the RRU subsite is implemented. Compared with a power control shutdown method in the prior art, the present invention reduces power consumption of base stations and the mobile terminal as well as uplink and downlink interference of a network.

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...
