Abstract:
1. In a wireless communication system including a base station and a plurality of wireless transmit/receive units (WTRUs), the base station including a plurality of antennas grouped into base station antenna groups, and at least one of said WTRUs including at least two antennas, wherein the number of antennas of the base station is not less than the number of antennas of any of the WTRUs, a method for implementing multi-user virtual multiple-input multiple-output (MIMO), the method comprising: the base station generating a multipath channel matrix between each WTRU and each base station antenna group, wherein the multipath channel matrix comprises channel coefficients for the antennas associated with each WTRU and the antennas associated with each base station antenna group of the base station; the base station generating an effective channel matrix for channels between the base station and the WTRUs, wherein the effective channel matrix comprises the multipath channel matrices for each WTRU and is an effective MIMO channel for the multi-user virtual MIMO; and the base station processing received signals from the WTRUs using the effective channel matrix.
