Abstract

The embodiments of the invention provide a power control method. The method comprises: a base station emitting a reference signal through first emission power; and the first base station receiving power control performed on the first emission power of the first base station by a second base station, the first base station being disposed in the coverage scope of the second base station. The embodiments of the invention further provide a base station. Single emission power is employed for trying, and a macro base station, through determining the interference bought to surrounding cells by use of the tried emission power by a micro base station, decides whether to adjust the emission power of the micro base station of maintain current emission power, such that the downlink power control of the micro base station by the macro base station is realized.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and more specifically, to a power control method and a base station. Background technique [0002] Third Generation Partnership Project (3 rd Generation Partnership Project (3GPP) Long Term Evolution-Advanced (LTE-A) Rel-10 / 11 / 12 releases are enhancements to Long Term Evolution (LTE) Rel-8 / 9 releases, LTE-A The system has higher bandwidth requirements than the LTE system and supports a peak data rate of up to 1G / s. In order to meet the requirements of LTE-A, the LTE-A system uses the carrier aggregation (Component Aggregation, CA) technology as its method to expand the system bandwidth, and uses a large number of multiple-input multiple-output (Multiple-Input Multiple-Output, MIMO) enhancement technology and Adaptive technology increases data rate and system performance. [0003] In the Rel-12 version, enhancement for hotspot regions becomes a hot topic. Hotspot areas include i...
