Methods and apparatus for feedback computation and decoding with synchronously coded subcarriers in OFDMA systems
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE receives pilot signals from a serving base station and at least one interfering base station. The UE determines phase rotations used by the serving base station and the at least one interfering base station for transmitting resource blocks. The UE determines channel feedback based on the received pilots signals and the determined phase rotations for each of the serving base station and the at least one interfering base station. The UE sends the channel feedback to the serving base station. The UE receives data based on the determined phase rotations.
