| 1. A method of providing feedback to support restrictive reuse in a single code word (SCW) multiple-input multiple-output
(MIMO) system, comprising:
sending a quality indicator for a non-restrictive reuse set to a scheduler, wherein the quality indicator is based at least
in part upon a direct measurement;
sending a vectored quality indicator for all reuse sets other than the non-restrictive reuse set for all layers to a scheduler,
wherein the vectored quality indicator is based at least in part upon a direct measurement; and
scheduling a terminal in a reuse set based in part on at least one of the quality indicator or the vectored quality indicator,
wherein the quality indicator includes two bits for rank and six bits for said quality indicator (CQI) for the non-restrictive
reuse set.
