Methods, wireless communication stations, and system for device coexistence in the 5 GHZ frequency band

摘要

Embodiments of a user station (STA) and methods for operating in a wireless communication network are generally described herein. In some embodiments, a STA separates a signal, into subchannels. The signal may be received on a wireless communication channel. The STA may detect a Short Training Sequence (STS) portion of a data packet on a subchannel of the subchannels. The STA may apply a coexistence technique, such as refraining from transmitting STA transmissions, on the channel responsive to the detecting.

1. A method, performed by a user station (STA), for operating in a wireless network, the method comprising:
separating a signal, received on a wireless communication channel in a frequency spectrum comprising 5 GHz, into subchannels, wherein a bandwidth of the subchannels into which the channel is separated is based on an expected bandwidth of transmissions of a device operating on a 5 GHz transmission band, on a frequency ranging from 5.85 GHz to 5.925GHz, in accordance with a standard of the Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards; detecting a Short Training Sequence (STS) portion of a data packet on a subchannel of the subchannels, wherein the separating includes filtering the signal into subchannels with bandwidths of 10 MHz and into subchannels with bandwidths of 5 MHz, and the detecting includes inspecting the 10 MHz subchannels, in parallel with each other, and the 5MHz subchannels in parallel with each other for a time duration based on a periodicity of the STS portion, and terminating the inspecting if the inspection of the 10 MHz subchannels detects the STS portion on one of the 10 MHz subchannels; and applying a coexistence technique on the channel, responsive to the detecting, by refraining from transmitting on the channel.
