Abstract
In a MIMO wireless communication system, a plurality of base stations (BSs) are provided each of which can transmit signals to, and receive signals transmitted from, one or more user equipments (UEs). The BSs are also organized into a plurality of groups. In a given group of BSs serving one or more UEs, those serving BSs coordinate with each other to simultaneously transmit signals to the one or more served UEs, and one or more of the served UEs feed back information to one or more of those serving BSs. The fed back information incorporates inter-group noise information related to interference between different BS groups. The method involves processing signals for simultaneous transmission by BSs of a group to one or more UEs served by that group and using the information fed back to the BSs of that group to improve system performance.
