1. A wireless communication device configured to scan for an access point, comprising:
- a baseband processor configured to generate a data download command comprising a preferred network list comprising a list of preferred network identifiers associated with access points to be scanned for, and a first scan command when the baseband processor enters deep sleep mode; and
a WLAN processor configured to receive the data download command and the first scan command, wherein the first scan command informs the WLAN processor that the baseband processor is entering deep sleep mode and triggers the WLAN processor to independently begin scanning a number channels corresponding to the preferred network identifiers while the baseband processor is deactivated.

Abstract
Techniques are provided for scanning for access points with a wireless communication device including a baseband processor and a WLAN processor. A data download command which defines a preferred network list can be sent from the baseband processor to the WLAN processor. In addition, a first scan command can be sent from the baseband processor which triggers the WLAN processor to independently begin periodically scanning a number channels.

13. A wireless communication device configured to scan for an access point, comprising:
-
a baseband processor configured to generate a data download command comprising a preferred network list comprising a list of preferred network identifiers associated with access points to be scanned for, a first scan command, and wherein the baseband processor is configured to send a configure wake-up command; and a WLAN processor configured to receive the data download command and the first scan command, wherein the first scan command triggers the WLAN processor to independently begin scanning a number channels corresponding to the preferred network identifiers while the baseband processor is deactivated, wherein the configure wake-up command defines when the WLAN processor generates a wake-up command for the baseband processor. - View Dependent Claims (14)

15. A method of scanning for an access point with a wireless communication device comprising a baseband processor and a WLAN processor, the method comprising:
-
sending a data download command from the baseband processor to the WLAN processor, wherein the data download command defines a preferred network list comprising a list of preferred network identifiers associated with access points to be scanned for; and sending, when the baseband processor enters deep sleep mode, a first scan command from the baseband processor to a firmware module of the WLAN processor, wherein the first scan command indicates that the baseband processor is entering deep sleep mode and triggers the WLAN processor to independently begin scanning a number channels corresponding to the preferred network identifiers at a defined scanning interval while the baseband processor is deactivated. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A wireless communication device configured to scan for an access point in accordance with a user-defined scan interval, the wireless communication device comprising:
-
a WLAN processor; and a baseband processor configured to generate; a data download command comprising a preferred network list comprising a list of preferred network identifiers associated with access points to be scanned for and scanning criteria for use by the WLAN processor including the user-defined scanning interval, and a first scan command when the baseband processor enters deep sleep mode, wherein the WLAN processor is configured to; receive the data download command and the first scan command, wherein the first scan command informs the WLAN processor that the baseband processor has entered deep sleep mode; scan, in response to the first scan command, a number channels corresponding to the preferred network identifiers associated with access points to be scanned for according at the user-defined scanning interval. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34)
