1. A method of enabling reduced power consumption in wireless devices operating in a network, comprising:
- generating, by a wireless device, a first message, the first message including a field, the field indicating beacon transmit window information, the beacon transmit window information indicating a duration of a beacon window during which one or more beacon messages are transmittable by the wireless device or other wireless devices; and
transmitting the first message on the network at a time prior to a start of the beacon window,wherein the first message further indicates one or more of discovery query window information or discovery query response window information,wherein the discovery query window information indicates a second duration of a discovery query window during which discovery query messages are transmittable on the network, each discovery query message requesting one or more services, andwherein the discovery query response window information indicates a third duration of a discovery query response window during which discovery query response messages are transmittable on the network, each discovery query response message responding to a discovery query message and indicating one or more services that are provided by a node transmitting the discovery query response message.

Abstract
Methods, apparatus, and computer readable storage mediums for enabling reduced power consumption in wireless devices operating in a neighbor aware network are disclosed. In one aspect, a method includes generating a first message, the first message indicating beacon transmit window information, the beacon transmit window information indicating a first time interval when one or more beacon messages are transmittable, and transmitting the first message on the neighbor aware network.

19. A method of saving power in a wireless device when operating in a network that provides communication between stations, comprising:
-
receiving, by a wireless device, a first message, the first message including a field, the field indicating beacon transmit window information, the beacon transmit window information including a duration of a beacon window during which one or more beacon messages are transmittable on the network by the wireless device or other wireless devices; entering a sleep state during a time period outside the beacon window; and receiving or transmitting a beacon message during the beacon window, the first message being received at a time prior to a start of the beacon window, wherein the first message further indicates one or more of discovery query window information or discovery query response window information, wherein the discovery query window information indicates a second duration of a discovery query window during which one or more discovery query messages are transmittable on the network, each discovery query message requesting one or more services, wherein the discovery query response window information indicates a third duration of a discovery query response window during which discovery query response messages are transmittable on the network, each discovery query response message responding to a discovery query message and indicating one or more services that are provided by a node transmitting the discovery response message, and wherein the sleep state is entered during a time period outside both the beacon window and the second duration. - View Dependent Claims (20, 21, 22, 23)

24. An apparatus for saving power in a wireless device when operating in a network, comprising:
-
a receiver configured to receive a message, the message including a field, the field indicating beacon transmit window information, the beacon transmit window information including a duration of a beacon window during which one or more beacon messages are transmittable on the network by the apparatus or other apparatus; and a processor configured to cause the wireless device to enter a sleep state during a time period outside the beacon window, wherein the receiver is further configured to receive or transmit a beacon message during the beacon window, the message being received at a time prior to a start of the beacon window, wherein the message further indicates one or more of discovery query window information or discovery query response window information, the discovery query window information including a second duration of a discovery query window during which one or more discovery query messages are transmittable on the network, each discovery query message requesting one or more services, wherein the discovery query response window information indicates a third duration of a discovery query response window during which one or more discovery query response window messages are transmittable on the network, each discovery query response message responding to a discovery query message and indicating one or more services that are provided by a node transmitting the discovery query response message, and wherein the processor is further configured to cause the wireless device to enter the sleep state during a time period outside both the beacon window and the second duration of the discovery query window. - View Dependent Claims (25, 26, 27)
