Claim of US Patent No. 10,117,222

1. A method of communication comprising:receiving, at a second device of a data link group of a neighbor aware network (NAN), a message including an indication of whether a first device corresponding to a particular service is available during multiple time periods designated for devices of the data link group to operate in an active operating mode; and
transitioning, by the second device, to a low-power operating mode during one or more transmission windows corresponding to at least one time period of the multiple time periods in response to determining, based on the message, that the first device is unavailable during the at least one time period, wherein the one or more transmission windows comprise a subset of all transmission windows between a first discovery window and a second discovery window; and
transitioning, by the second device, to an active operating mode during at least one transmission window between the first discovery window and the second discovery window, wherein the second device is available to communicate with at least one device of the NAN during the active operating mode.
