Patent ID: 8804563

Claim:
A user equipment (UE) configure to perform channel estimation in a wireless communications network system, said UE comprising: a receiver circuit configured to receive a plurality of consecutive physical resource blocks from a radio base station; a channel estimator configured to estimate a channel coefficient of each received physical resource block; a calculator circuit configured to calculate for each two adjacent physical resource blocks, a difference between estimated channel coefficients of the two adjacent physical resource blocks; a comparator circuit configured to compare each calculated difference with a predefined threshold value; and an assembler circuit configured to group physical resource blocks for which said calculated difference is less than or equal to the predefined threshold value; wherein the channel estimator is further configured to perform a group-wise channel estimation on a group comprising physical resource blocks for which said calculated difference is less than or equal to the predefined threshold and to further perform per physical resource block channel estimation on each remaining physical resource block.
