Abstract:
1. A method of cancelling inter-channel interference between a first selected UE in one sector of a cell and a second selected UE in a second sector of said cell, comprising the steps of: a) estimating channel matrix blocks for said first and second selected UEs, said channel matrix blocks being representative of the channel characteristics between said first and second UE, in their respective sectors and a serving base station; b) loading said estimated channel matrix blocks into a cross-sector channel block matrix; c) calculating the inverse values of said channel block matrix to form a sector specific cross-sector pre-coding matrix; d) performing a pre-coding operation on input data of the formed pre-coding matrix to generate an output signal; and e) using said pre-coding matrix output signals to enable interference cancellation.
