摘要:
An electronic device includes a first circuit (111) operable to generate a precoding matrix index (PMI) vector associated with a plurality of configured subbands, and further operable to form a compressed PMI vector from the PMI vector wherein the compressed PMI vector includes one reference PMI and at least one differential subband PMI defined relative to the reference PMI; and a second circuit (113) operable to initiate transmission of a signal communicating the compressed PMI vector. Other electronic devices, processes and systems are also disclosed.
