Multi-radio time base
First Claim
1. A first wireless device comprising:
- a wireless local area network (WLAN) module configured to selectively operate in a power save mode, wherein while not operating in the power save mode, the WLAN module is configured to communicate with a second wireless device;
a mobile phone radio module configured to receive, in accordance with a mobile phone protocol, base station time reference information from a base station;
a time module configured to maintain, at least while the WLAN module is operating in the power save mode, a base station time reference based on the base station time reference information received in accordance with the mobile phone protocol; and
a sleep module configured to control, based on the base station time reference maintained by the time module, when the WLAN module exits the power save mode to permit the WLAN module to communicate with the second wireless device.

Abstract
A method including selectively operating a wireless local area network (WLAN) module of a first wireless device in a power save mode. The method includes, while not operating the WLAN module in the power save mode, communicating wirelessly with a second wireless device using the WLAN module. The method includes receiving, in accordance with a mobile phone protocol, base station time reference information from a base station. The method includes maintaining, at least while operating the WLAN module in the power save mode, a base station time reference based on the base station time reference information received in accordance with the mobile phone protocol. The method includes controlling, based on the maintained base station time reference, when the WLAN module exits the power save mode to permit the WLAN module to communicate with the second wireless device.
