Title:
INTERFERENCE CANCELLATION IN BEAMFORMING TRANSCEIVERS
Document Type and Number:
WIPO Patent Application WO/2019/155092
Kind Code:
A8
Abstract:
A solution for interference cancellation is disclosed, comprising determining (300) communication parameters for a set of phased subarrays each configured to transmit or receive an independent data signal utilising a beam at a given direction, determining (302) for each subarray direction of the transmitted or received signal and interference level caused by each other subarray of the apparatus in the directions used by the subarrays, forming (304) from the data signal of each other subarray in the direction used by the subarray a cross-coupling signal having an amplitude similar to the determined interference level, inverting (306) the phase of the cross-coupling signal of each other subarray and combining (308) the cross-coupling signals of each other subarray with the independent data signal of each subarray.
