Abstract:
1. A method executed in a mobile station that communicates with a base station, said mobile station having multiple mobile station antennas, and said base station having M base station antennas, M being an integer greater than one, said method comprising: determining in said mobile station channel conditions between said mobile station antennas station and said base station antennas; and sending a request to said base station, contents of said request based on said channel conditions, said request requesting said base station to send information coded for Co-Channel interference (CCI) suppression, Multiple-Input-Multiple-Output (MIMO) reception, or to send information coded for both CCI suppression and MIMO reception, said request requesting said base station to send a particular stream of information through multiple ones of said base station antennas when requesting information coded for said CCI suppression, and to send multiple different streams of information, each of the multiple different streams being sent over a different one of the base station antennas, when requesting information coded for said MIMO reception; where, when said determining concludes, by performing comparisons, that Signal-to-Interference-and-Noise Ratio (SINR) is higher than a preselected first threshold and channel fading correlation is lower than a preselected second threshold, said request is for MIMO reception, and where, when said determining concludes, by performing comparisons, that Signal-to-Interference-and-Noise Ratio (SINR) is not higher than a preselected first threshold or channel fading correlation is not lower than a preselected second threshold, said request is for CCI suppression.
