Adaptive sinr control
ActiveUS20100130133A1Improve signal interferenceEnhanced signalPower managementRadio transmissionGeographic regionsTransmitted power
An adaptive SINR control process is triggered based on various quality measures associated with the received signal in a mobile device or on a geographic region in which a base station and an interferer are located. As part of the adaptive SINR control process the mobile device reduces the signal level of the received signal, which reduces both the signal strength of the desired signal and interfering signal. If the control process is triggered on the mobile device side, after detecting the presence of interference, the mobile device sends a request that the base station increases its transmit power of the desired signal to improve the receiving SINR in the mobile device. Alternatively, the mobile device may receive information from the base station causing the mobile device to reduce the signal level of the received signal based on quality indicators sent by the mobile device to the base station or based on geographic location of the base station.
