Abstract

The invention discloses a subdistrict division power configuration method and a system. The method comprises the following steps: calculating the maximum value of the descending transmission power ability of all current subdistrict divisions when receiving a power configuration request; configuring the actual descending maximum transmission power of every current subdistrict division according tothe maximum value of descending transmission power ability and subdistrict descending maximum configuration power preset in the power configuration request; and configuring the actual descending channel transmission power of every current subdistrict according to the maximum value of the descending transmission power ability and channel configuration power preset in the power configuration request. The invention can effectively solve the problem of power configuration of the maximum transmission power of every subdistrict division of a time-division duplex-station descending subdistrict and acommon channel and a shared channel under every subdistrict division.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and a system for power configuration in cell divisions. Background technique [0002] Implementing Cell Portion under TDD (Time Division Duplex) can improve the application scenarios of smart antennas and solve networking and coverage problems in complex scenarios. [0003] At present, the 3GPP protocol does not provide a method for configuring Cell Portion power under TDD, including the maximum transmit power of the cell, the power of common channels and shared channels. Contents of the invention [0004] In view of the above analysis, the present invention aims to provide a method and system for cell partition power configuration to solve the problem that the 3GPP protocol in the prior art does not provide the implementation of Cell Portion power configuration under TDD. [0005] The purpose of the present invention is achieved through the fol...
