Abstract
A base station for a wireless network uses one or more MIMO channels having subchannels, to communicate with multiple user equipments, and allocates the sub channels to the user equipments. Different subchannels of a given one of the channels can be allocated to different user equipments. The ability to allocate sub channels individually rather than only allocating entire channels can enable higher data rates can be achieved. This is particularly useful for improving data rates at cell boundaries or sector boundaries, where the coverage is traditionally weakest. A user equipment can use subchannels from different MIMO channels from different sectors or from different base stations.
