Abstract
A method (500) is provided for dynamic packet polling during a power save mode. The method can include polling (504) an access point (104) for packets at a first rate on at least one access category, determining (506) a polling time-out as a function of a packet priority, and possibly changing the rate to a second rate in view of a second packet priority. The polling time-out can correspond to a duration interval of the polling for increasing an efficiency of the power save mode. The method can include establishing a poll timeout and an overall poll timeout as a function of each access category. The function can include mapping a packet priority to a response time for setting a timeout. In one aspect, the polling can be combined into a single polling stream for multiple access categories.
