Abstract  Abstract

A wireless communication system facilitates multichannel periodic and aperiodic feedback (e.g. Channel Quality Indicator (CQI) Rank indicator (RI) Precoding Matrix Indicator (PMI)) from a population of user equipment while facilitating legacy single carrier communication. Paired downlink (DL)/ uplink (UL) or many-to-one mapping communication can be established by common system information or dedicated signaling. In one aspect a flag sent by system information or by dedicated signaling can indicate which means controls. Feedback can be configured for each carrier independently reported in a concatenated in frequency fashion reported in a cycle in time fashion or reported in a staggered in time and frequency fashion. Feedback can be reported jointly as one wide bandwidth. Feedback can be a single report perhaps reported on a data channel for more capacity or by cycled carrier/subband reporting.
