Claim 5:
6. A method for indicating the number of multi-user multiple-input multiple-output (MU-MIMO) users, comprising:
receiving a physical layer protocol data unit (PPDU), wherein the PPDU comprises a signal field B, the signal field B comprises at least one resource unit allocation subfield, the at least one resource unit allocation subfield is a resource unit allocation index, the resource unit allocation index is used to indicate a resource unit arrangement and combination, the resource unit allocation index is further used to indicate the number of MU-MIMO users supported in a resource unit that consists of at least 106 subcarriers, and the number of MU-MIMO users is greater than 8; and
determining, based on the at least one resource unit allocation subfield, the number of MU-MIMO users supported in the resource unit that consists of at least 106 subcarriers.
