Patent ID: 8472547

Claim:
A method in a first wireless communication transceiver of controlling precoder selection feedback sent to a second wireless communication transceiver that precodes transmissions to the first wireless communication transceiver, wherein said precoder selection feedback indicates precoder selections by said first wireless communication transceiver, said method comprising: receiving restriction signaling from the second wireless communication transceiver that identifies: one or more permitted subsets within a defined set of overall precoders, each of which comprises a combination of a conversion precoder from a defined set of conversion precoders and a tuning precoder from a defined set of tuning precoders, or, one or more permitted subsets of precoders within the defined sets of said conversion precoders and tuning precoders; and generating said precoder selection feedback for sending to the second wireless communication transceiver based on restricting precoder selections by said first wireless communication transceiver according to said restriction signaling.
