OFDMA system method for the feedback calculation and decoding using the sub-carriers, which are coded in sync in and equipment

摘要

A method for wireless communications, equipment, and computer program is provided. Device may be in the UE. The UE receives the pilot signals from the serving base station and the at least one interfering base station. The UE determines the phase rotation to be used by the serving base station and at least one interfering base station to transmit a resource block. The UE determines the channel feedback based on the phase rotation that is determined received pilot signals, and for each of the serving base station and the at least one interfering base station. The UE transmits the channel feedback to the serving base station. UE receives the data based on the phase rotation that has been determined.
