METHODS AND APPARATUS FOR IMPROVING POWER EFFICIENCY AND LATENCY OF MOBILE DEVICES USING AN EXTERNAL TIMING SOURCE
First Claim
1. A method of increasing power efficiency and decreasing latency of communication of a mobile device operating in an unlicensed spectrum using global timing data, the method comprising:
- receiving, at the mobile device, the global timing data from an external timing source, the mobile device communicating in the unlicensed spectrum;
obtaining, at the mobile device, a time from the global timing data; and
determining, at the mobile device, a wake time to switch the mobile device from a sleep state to an active state based on the time obtained from the global timing data.
