SYSTEMS AND METHODS FOR 8-TX CODEBOOK AND FEEDBACK SIGNALING IN 3GPP WIRELESS NETWORKS

Document Type and Number:

WIPO Patent Application WO/2012/002747

Kind Code:

A3

Abstract:

A mobile station for use in a wireless network. The mobile station is operable to transmit feedback values to a base station of the wireless network. The feedback values include a first precoder matrix indicator (PMI1) value and a second precoder matrix indicator (PMI2) value. The mobile station transmits the PMI2 value to the base station in the same subframe as a channel quality indicator (CQI) value. The CQI value may be either a wideband CQI value or a subband CQI value.
