Channel quality reporting for adaptive sectorization

摘要

Apparatuses and methodologies are described that enhance performance in a wireless communication system using beamforming transmissions. According to one aspect, the channel quality is monitored. Channel quality indicators can be used to select a scheduling technique, such as space division multiplexing (SDM), multiple-input multiple output (MIMO) transmission and opportunistic beamforming for one or more user devices. In addition, the CQI can be used to determine the appropriate beam assignment or to update the beam pattern.

1. A method for enhancing performance for a wireless communication environment, comprising:
receiving a pilot; calculating an instantaneous channel quality indicator (CQI) based at least in part upon the pilot; calculating a long term CQI based at least in part upon the instantaneous CQI; and reporting the long term CQI in order to enable a modification of a condition of the wireless communication environment based at least in part on the reported long term CQI, the reporting being performed responsive to the occurrence a beam pattern change, a user device beam coverage change, a drop by the long term CQI below a predetermined threshold, or a combination thereof.
