Abstract
An embodiment of a system for the coexistence of a wireless local area network (WLAN) and another type of wireless transmission is provided. A WLAN module in a power saving mode is configured to transmit a polling request (PS-Poll) at a supported rate higher than any basic rate in order to obtain buffered data from an access point (AP) when the coexisting wireless transmission module is operating. The supported rate is encoded in a supported rate set announced by the AP, and the basic rate is encoded in a basic rate set announced by the AP, and the PS-Poll is a polling request relating to a power saving mode of operation.
Claims16
A system for the coexistence of a wireless local area network (WLAN) in a power saving mode and another type of wireless transmission, comprising:
- a WLAN module transmitting a polling request (PS-Poll) at a supported rate higher than any basic rate in order to obtain buffered data from an access point (AP) when a coexisting wireless transmission module is operating,
- wherein the supported rate is encoded in a supported rate set announced by the AP, and the basic rate is encoded in a basic rate set announced by the AP, and the PS-Poll is a polling request relating to a power saving mode of operation.
A method for wireless local area network (WLAN) transmission, performed by a media access control (MAC) unit, comprising:
- transmitting a polling request (PS-Poll) at a supported rate higher than any basic rate in order to obtain buffered data from an access point (AP) when a coexisting Bluetooth or WiMAX module is operating,
- wherein the supported rate is encoded in a supported rate set announced by the AP, and the basic rate is encoded in a basic rate set announced by the AP.
