APPARATUS AND METHOD FOR CHANNEL ESTIMATION IN A WIRELESS COMMUNICATIONS SYSTEM

摘要

The exemplary embodiments of the present invention relate to a user equipment and to a method for channel estimation in a wireless communications network system. The method comprises: receiving physical resource blocks from a radio base station; estimating a channel coefficient of each received physical resource block; calculating for each two adjacent physical resource blocks, a difference between estimated channel coefficients of the two adjacent physical resource blocks; comparing each difference with a predefined threshold value; grouping physical resource blocks for which said difference is less than or equal to the predefined threshold value; and performing a group-wise channel estimation and per physical resource block channel adaptively.
