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

Claim 0:
1. 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) OM (Operating Mode) Control field or another element;
wherein the processor is further configured to define a new EHT (Extreme High Throughput) OM (Operating Mode) Control field to announce EHT operating parameter changes; and
wherein the processor is further configured to combine the new EHT OM Control field with the HE OM Control field to announce the operating parameter changes when either Rx/Tx Nss is more than 8 or a bandwidth is more than 160 MHz.
