Adaptive SINR control

摘要

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 the 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 increase 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.

主权项

1. A method for comprising:
determining at a mobile device presence of interference from an interfering signal in a received signal; in response to determining the presence of interference from the interfering signal, sending a request to an assigned base station of the mobile device to increase transmission power of a desired signal; and reducing a signal level of the received signal at the mobile device in response to receiving an acknowledgement to the request from the assigned base station, the received signal including the desired signal and the interfering signal.
