1. A method for wireless communications, the method comprising:
operating an Access Point (AP) to receive a sounding feedback report from a client for a sounding bandwidth up to 320 MHz;
signaling, by the AP, to flail the client, in a Null Data Packet Announcement (NDPA) frame a feedback subcarrier location set on which flail the feedback report is solicited;
and
indicating, by the client, feedback subcarrier indices for the subcarrier location set via the feedback report solicited by the AP;
wherein for the sounding bandwidth of at most 160 MHz, the feedback subcarrier location set is indicated by 9-bits which indicate each of the possible combinations for an aggregation of 242-sized Resource Units (RUs) for the sounding bandwidth, wherein for the sounding bandwidth greater than 160 MHz, the feedback subcarrier location set is indicated by 9-bits which indicate each of the possible combinations for an aggregation of 484-sized RUs for the sounding bandwidth, and wherein an aggregation of more than two RUs is considered.
