Problems solved by technology

[0003] Therefore, the power allocation of the existing LTE-G 230M system will cause the problem of power mismatch between uplink and downlink, and then there will be a waste of base station power caused by the single subband of the base station still transmitting according to the maximum transmission power in the scenario where the uplink power is limited

Abstract

The embodiment of the invention provides a base station sub-band power distribution method and device. The method comprises the steps: determining the type of a user terminal if a judgment result shows that a target sub-band is occupied by the user terminal; and setting the transmitting power of the target sub-band according to the type of the user terminal. According to the base station sub-bandpower distribution method and device provided by the embodiment of the invention, different terminal types are identified, and the single sub-band transmitting power of the base station is dynamicallyadjusted according to the terminal types so as to improve the utilization rate of the base station power, so that the power loss is reduced on the premise of not reducing the system performance.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a method and device for subband power allocation of a base station. Background technique [0002] In terms of power usage of the current 230MHz discrete multi-carrier power wireless communication system based on LTE-G technology (hereinafter referred to as the LTE-G230MHz system), the power of various service types of subbands is consistent. There are different types of terminals distributed under a base station, including single-subband terminals and multi-subband terminals. The single-subband transmit power of the base station can transmit up to 27dBm, and the maximum transmit power of each type of terminal is not greater than 23dBm. For multi-subband terminals, each The transmit power of each subband will also decrease as the number of subbands increases. [0003] Therefore, the power allocation of the existing LTE-G 230M system will cause the problem ...
