1. An access point apparatus complying with an IEEE802.11 series standard, comprising:
at least one memory that stores a set of instructions; and
at least one processing circuit that executes the set of instructions to cause the access point apparatus to:
receive, from a station apparatus, a Medium Access Control (MAC) frame, wherein the MAC frame includes a first subfield and a second subfield, wherein the first subfield represents whether an Uplink Multi User (UL MU) communication function is supported or not, wherein the UL MU communication function is a function of transmitting data in response to a triggering frame, and wherein the second subfield is used to represent whether the UL MU communication function is enabled or disabled;
determine, by interpreting the the first subfield and the second subfield, that the UL MU communication function is enabled by the station apparatus in a case where the first subfield represents that the UL MU communication function is supported by the station apparatus and the second subfield contains a value to represent that the UL MU communication function is enabled; and
determine, by interpreting the first subfield and the second subfield, that the UL MU communication function is disabled by the station apparatus in a case where the first subfield represents that the UL MU communication function is supported by the station apparatus and the second subfield contains a value to represent that the UL MU communication function is suspended.
