OPERATING PARAMETER UPDATE WITH WIDER BANDWIDTH

摘要

Various embodiments relate to a method performed by 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, including: announcing by the first device original capabilities to the second device; receiving an announcement of capabilities from the second device; receiving frames from the second device in PHY Protocol Data Units (PPDUs) following the first protocol and the second protocol; announcing by the first device a change in its capabilities to the second device; and receiving frames from the second device in PPDUs transmitted using the changed capabilities following the first protocol and the second protocol, wherein the change in the capabilities includes a change in a one of a puncture parameter, bandwidth parameter, mode and coding scheme (MCS) parameter, and a number of simultaneous streams (Nss) parameter.
