Problems solved by technology

Since the BSC adjusts the transmit power of the base station for power control according to the measurement report information, it takes at least 470ms or 480ms to update the judgment information once. When the network environment changes rapidly, the transmit power control of the base station may not be timely enough

Abstract

The embodiment of the invention discloses a base station power control method, comprising the following steps: receiving a coding mode request (CMR) sent by user equipment (UE), requesting a base station by the CMR to send data to the UE in the coding mode in the CMR; obtain the coding mode in the CMR; and regulating the transmission power of the base station according to the coding mode. By utilizing the method of the embodiment of the invention, empty-port quality is judged according to the coding mode in the CMR, and the transmission power of the base station is regulated also on the basisof the coding mode in the CMR, thus the transmission power of the base station can be regulated timely according to the change of network environment.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a base station power control method and equipment in the field of communication systems. Background technique [0002] In a communication system, power control is required for both uplink and downlink. When the level and quality of the received signal at the receiving end are very good, the transmission power of the opposite end can be appropriately reduced to keep the communication quality at a certain level, which can reduce the interference to other calls in the surrounding area. [0003] In the prior art, the communication system judges whether to adjust the transmit power of the base station according to the current communication quality, and how to adjust the transmit power of the base station if the transmit power of the base station needs to be adjusted. Taking the Global System for Mobile Communication (GSM for short) communication system as an example, the trans...
