Abstract
An electronic device includes a first circuit (111) operable to generate at least a first and a second channel quality indicator (CQI) vector associated with a plurality of subbands for each of at least first and second spatial codewords respectively and generate a first and a second reference CQI for the first and second spatial codewords, and operable to generate a first and a second differential subbands CQI vector for each spatial codeword and generate a differential between the second reference CQI and the first reference CQI, and further operable to form a CQI report derived from the first and the second differential subbands CQI vector for each spatial codeword as well as the differential between the second reference CQI and the first reference CQI; and a second circuit (113) operable to initiate transmission of a signal communicating the CQI report. Other electronic devices, processes and systems are also disclosed.
