Patent ID: 8687678

Claim:
A method in a first wireless communication transceiver of generating precoder selection feedback to a second wireless communication transceiver that precodes transmissions to the first wireless communication transceiver, wherein said precoder selection feedback indicates precoder selection by said first wireless communication transceiver, wherein a defined set of overall precoders is represented by defined sets of conversion precoders and tuning precoders such that each overall precoder in the defined set of overall precoders 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, said method comprising: receiving restriction signaling from the second wireless communication transceiver that indicates at least one of a permitted subset of conversion precoders of said defined set of conversion precoders, and a permitted subset of tuning precoders of said defined set of 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.
