Claim of US Patent No. 10,924,227

1. A method for transmitting a radio frame comprising:generating, by an apparatus, a radio frame that includes a common information part and a user information part,
wherein a field in a sounding dialog token in the common information part indicates information of a standard to which the radio frame corresponds, wherein the standard comprises a first standard or a second standard,
wherein the user information part comprises one or more station information fields, wherein a length of a station information field is M bytes corresponding to information of the first standard, and a length of a station information field is MK bytes corresponding to information of the second standard, and
wherein for a station information field that corresponds to information of the second standard, a beginning M bytes of the MK bytes includes an association identifier (AID) field, and each following M bytes of the MK bytes after the beginning M bytes does not include any AID field, wherein M is an even natural number larger than 4, a most significant bit (MSB) of the front 12 bits of the each following M bytes of the MK bytes after the beginning M bytes is set to 1, wherein the MSB of the front 12 bits is a bit B in the station information field, wherein B=8Mj+11, wherein j=1, 2, 3, . . . , K?1, and wherein K is a natural number larger than 1; and
transmitting, by the apparatus, the radio frame.
