A METHOD FOR ADAPTIVELY DECIDING THE NUMBER OF FEEDBACK RESOURCE BLOCKS IN A DOWNLINK

摘要

A method for adaptively deciding the number of feedback resource blocks in a downlink. The method includes the following steps: a base station (500) determines the mode that a user equipment (100) feeds the number of resource blocks by monitoring the performance of a wireless zone and the number of user equipments; the base station (500) transmits the mode to the user equipment (100) by signaling; the user equipment (100) intercepts the mode and adaptively decides the number of feedback resource blocks according to the status of itself; the user equipment (100) feeds the information of the downlink channel quality indicator to the base station (500) using a feedback algorithm based on the best channel quality indicator number or a feedback algorithm based on a threshold of channel quality indicator; finally, the base station (500) performs scheduling of resource according to the feedback information. The present invention discloses a method for adaptively deciding the number of feedback resource blocks based on base station signaling and user equipment deciding, with respect to a feedback algorithm based on the best channel quality indicator number or a feedback algorithm based on a threshold of channel quality indicator in the downlink, thus insuring the performance of wirelesszone.
