Abstract
A method is presented for dedicating and allocating frequency channels to control and data frames in a WiFi local area network system. The method comprising dedicating a frequency channel in a frequency band, determining by a station the dedicated frequency channel, transmitting by the station a probe request frame in the dedicated frequency channel, receiving by the station a probe response frame in the dedicated frequency channel.
Claims13
A method for wireless communication, the method comprising:
- dedicating a frequency channel in a frequency band;
- determining, by a station, the dedicated frequency channel by decoding, by the station, an information element within a beacon frame;
- transmitting, by the station, a probe request frame in the dedicated frequency channel based on the beacon frame;
- receiving, by the station, a probe response frame in the dedicated frequency channel,
- wherein a separate frequency channel from the dedicated frequency channel is in the frequency band and is allocated for transmitting data frames upon receiving the probe response frame,
- wherein the beacon frame in the dedicated frequency channel is transmitted more often than the beacon frame in the separate frequency channel,
- wherein the dedicated frequency channel and the separate frequency channel are allocated by decoding, by the station, the information element within the beacon frame, and
- wherein the information element indicates the dedicated frequency channel dedicated to the probe request frame and the probe response frame, and indicates the separate frequency channel.

A method for wireless communication comprising:
- allocating a first frequency channel in a first frequency band;
- allocating a second frequency channel in a second frequency band;
- transmitting, by a station, a probe request frame in the first allocated frequency channel based on a beacon frame;
- receiving, by the station, a probe response frame in the first allocated frequency channel;
- transmitting, by the station, a first data frame in the second allocated frequency channel, upon receiving the probe response frame;
- receiving, by the station, a second data frame in the second allocated frequency channel,
- wherein the first allocated frequency channel and the second allocated frequency channel are allocated by decoding, by the station, an information element within the beacon frame,
- wherein the information element indicates the first allocated frequency channel dedicated to the probe request frame and the probe response frame, and indicate sthe second allocated frequency channel, and
- wherein the beacon frame in the first allocated frequency channel is transmitted more often than the beacon frame in the second allocated frequency channel.

A method for wireless communication comprising:
- dedicating a frequency channel in a frequency band;
- determining, by an access point, the dedicated frequency channel by decoding, by the access point, an information element within a beacon frame;
- receiving, by the access point, a probe request frame generated based on the beacon frame in the dedicated frequency channel;
- and
- transmitting, by the access point, a probe response frame in the dedicated frequency channel,
- wherein a separate frequency channel from the dedicated frequency channel is in the frequency band and is allocated for transmitting data frames, upon transmitting the probe response frame,
- wherein the beacon frame in the dedicated frequency channel is transmitted more often than the beacon frame in the separate frequency channel,
- wherein the dedicated frequency channel and the separate frequency channel are allocated by decoding, by the station, the information element within the beacon frame, and
- wherein the information element indicates the dedicated frequency channel dedicated to the probe request frame and the probe response frame, and indicates the separate frequency channel.
