Abstract
A method and apparatus of switching a band in a wireless local access network (WLAN) is provided. The method includes transmitting a multi-band switch request message to request switching from a first frequency band to a second frequency band, and receiving a multi-band switch response message in response to the multi-band switch request message. The multi-band switch request message includes a multi-band switch schedule to operate in the second frequency band. Wider coverage can be supported by using multi-band.
Claims13
A method of operating in a power save mode in a wireless local access network (WLAN), the method comprising:
- transmitting, by a first station operating in a first frequency band, to a second station, a multi-band switch request message which requests switching to a second frequency band, wherein the multi-band switch request message includes a switching channel information indicating the second frequency band and a wakeup schedule for operating in the power save mode in the second frequency band;
- receiving, by the first station, a multi-band switch response message in response to the multi-band switch request message from the second station, the multi-band switch response message comprising a status code indicating success or failure cause of the switching of frequency band;
- if the status code indicates the success, switching, by the first station, from the first frequency band to the second frequency band;
- and
- operating, by the first station, in the power save mode in the second frequency band according to the wakeup schedule;
- wherein the first station is a non-AP station and the second station is a non-AP station.
A wireless apparatus comprising:
- a processor configured to:
- transmit, to a second station, a multi-band switch request message which requests switching to a second frequency band, wherein the multi-band switch request message includes a switching channel information indicating the second frequency band and a wakeup schedule for operating in the power save mode in the second frequency band;
- receive a multi-band switch response message in response to the multi-band switch request message from the second station, the multi-band switch response message comprising a status code indicating success or failure cause of the switching of frequency band;
- if the status code indicates the success, switch from the first frequency band to the second frequency band;
- and
- operate in the power save mode in the second frequency band according to the wakeup schedule;
- wherein the second station is a non-AP station.
