Abstract

The invention discloses a method and a system for controlling uplink and downlink power, which relate to the field of wireless communication and can reduce the outdoor interference caused by indoor communication. According to the invention, according to downlink signal sampling data of an adjacent cell, a downlink interference control threshold corresponding to an indoor cell is calculated; according to the downlink signal sampling data of the indoor cell, an uplink interference control threshold corresponding to the indoor cell is calculated; during power control, judgment for downlink and / or downlink transmission power is implemented on a terminal inside the indoor cell, if the downlink transmission power of network side to the terminal is larger than the downlink interference control threshold according to the power control judgment result after the power control, power adjustment is not performed according to the judgment result, instead, the downlink transmission power of the terminal is adjusted to the downlink interference control threshold. And if the uplink transmission power of the terminal is larger than the uplink interference control threshold according to the power control judgment result after the power control, the uplink transmission power of the terminal is adjusted to the uplink interference control threshold.

Description

technical field

[0001] The invention relates to the field of wireless communication, in particular to power control technology. Background technique

[0002] Code Division Multiple Access (CDMA for short) communication system occupies a pivotal position in mobile communication, especially in the third generation of mobile communication (The Third Generation, referred to as "3G"), the three relatively mature standards All belong to the category of CDMA. In a CDMA system, because all users share the same frequency, the mutual interference problem is prominent, so power control is very critical. Whether it is uplink or downlink, it is very necessary to keep the transmit power at the minimum power level that can meet the communication quality requirements, because too small power will cause users to be dissatisfied with the communication quality, and too much power will reduce the operational efficiency of the communication system .

[0003] There are generally two power cont...
