7. The method of claim 5 , wherein the first parameter set is signaled to the first group of users and the second group of users using a unicast, a multicast, or a broadcast message.
8. A method for providing channel quality indicator (CQI) feedback for a station (STA), comprising:
forming a first group of users that use the first parameter set, the first group of users formed based at least in part on parameters specific to the first group of users;
forming a second group of users that use the first parameter set;
establishing a reporting frequency for hierarchal CQI feedback reporting, wherein the reporting frequency is based at least in part on a periodicity of forming groups of users;
determining a first node in a hierarchical tree to report first CQI feedback via the hierarchical CQI feedback reporting;
determining a subband that correlates with the first node;
associating with the first group of users in the subband;
reporting the first CQI feedback in a first frame, the first CQI feedback to comprise a CQI value and a node value of the first node; and
reporting second CQI feedback in a second frame using best-m CQI feedback reporting that is periodically triggered, a reporting frequency of the best-m CQI feedback reporting to be less than the reporting frequency of the hierarchical CQI feedback reporting.
9. The method of claim 8 , wherein the determining the first node in the hierarchical tree is based upon at least one of determining which subbands the STA was last allocated and a current modulation and coding scheme (MCS) for the STA.
10. The method of claim 9 , further including determining a second subband that correlates with the first node.
