Method, processor and base station for downlink power processing

Abstract

The invention discloses a downlink power processing method, a processor and a base station. According to the invention, the downlink power of N pre-configured non-authorized frequency points is reserved, and the downlink power of each non-authorized frequency point is a preset value P, wherein N is less than or equal to the number of pre-configured non-authorized frequency points. The method comprises the following steps: determining the number M of downlink sub-bands employed by a plurality of sub-band services according to the downlink rate information of the plurality of sub-band services when a request for processing the plurality of sub-band services is received; judging whether M is greater than N or not; sensing the usable frequency points in the pre-configured non-authorized frequency points if M is not greater than N; judging whether M is greater than the number Q of usable frequency points or not; distributing the downlink power of M usable frequency points to the plurality of sub-band services if M is not greater than Q, wherein the downlink power of each usable frequency point is P. Compared with the prior art, when the plurality of sub-band services needs to be carried out in a discrete narrow-band system, the method just need to add a few sub-bands to meet the bandwidth service demands, thereby reducing the impact on a cell coverage distance as much as possible.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a downlink power processing method, processor and base station. Background technique [0002] The transmit power of the base station determines the coverage of the cell and also affects the signal quality. For a multi-subband base station wireless system with a certain total power, that is, each base station in the wireless system is configured with multiple subbands, and the maximum power that each subband can achieve is inversely proportional to the number of subbands used in the system. When the system uses more sub-bands, the power of a single sub-band decreases, resulting in a decrease in cell coverage distance and a decrease in service signal quality; conversely, when the number of sub-bands used in the system is small, the power of a single sub-band is relatively large, and the coverage distance becomes larger , the service signal quality is improve...
