Assignee: NXP USA, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 18:
19. A first wireless device for announcing operating capabilities to a second wireless device, wherein the first wireless device and second wireless device support a first protocol and a second protocol, comprising:
a processor configured to,
announce original capabilities to the second wireless device;
receive an announcement of capabilities from the second wireless device;
receive frames from the second wireless device in PHY Protocol Data Units (PPDUs) encoded using the first protocol and the second protocol;
announce a change in the first wireless device operating parameters to the second wireless device; and
receive frames from the second wireless device in PPDUs transmitted using the changed operating parameters encoded using the first protocol and the second protocol,
wherein the change in the operating parameters includes a change in a one of a bandwidth parameter, modulation and coding scheme (MCS) parameter, and a number of simultaneous streams (Nss) parameter;
wherein the operating parameter changes are carried in either HE (High Efficiency) Control field or an element; and
wherein the operating parameters further include:
1-bit Additional BW, indicating whether the bandwidth is 320 MHz or not;
4-bit Additional Rx Nss where 8 values are for Nss values of 9 to 16 and an additional one value is used to indicate Rx Nss=8 and this value indicates the maximal Nss at 80 MHz; and
4-bit Additional Tx Nss where 8 values are for Nss values of 9 to 16 and additional one value is used to indicate Rx Nss=8 and this value indicates the maximal Nss at 80 MHz.
