Embodiment Construction

[0023] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0024] figure 1 It is a flowchart showing a power allocation method on a reverse link power control channel according to an embodiment of the present invention.

[0025] like figure 1 As shown, the power allocation method on the reverse link power control channel according to this embodiment includes the following steps: step S102, the base station determines the total power amount used on the reverse link power control channel; step S104, the base station The change of the forward channel quality information reported by the mobile terminal is used to determine the amount of power that needs to be allocated to the reverse link power control channel corresponding ...

Abstract

This invention discloses a power distribution method on reverse link power control channels including: a base station determines a total power volume used in reverse link power control channels and determines the power necessary to be distributed to the reverse link power control channels corresponding to mobile terminals according to the changes of the forward channel quality information reported by the mobile terminals and compares the total power with that needed for all the terminals to distribute the power on the reverse link power control channels.

Description

technical field [0001] The present invention relates to the field of wireless communication, and more specifically, to a power allocation method on a reverse link power control channel. Background technique [0002] In the Direct Sequence Code Division Multiple Access (DS-CDMA) system, different mobile terminals work on the same frequency at the same time, and the system communicates by assigning different code words to each mobile terminal (usually called a code channel). This makes the capacity and performance of the system highly dependent on the interference received by the mobile terminals. In a CDMA system, any method to reduce the interference suffered by mobile terminals will improve the performance of the system. As an effective means to reduce the interference between system channels, power control technology has become a key technology of CDMA communication system. [0003] Usually, a base station has a single amplifier responsible for transmitting a complete CD...
