Abstract

A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, an apparatus is configured to determine a multicast schedule for communicating data associated with a service over an NDL and to transmit the multicast schedule to at least one other wireless device.

First claim

What is claimed is:

1 . A method of wireless communication by a first wireless device, comprising:
determining a multicast schedule for communicating data associated with a service over a neighbor awareness networking (NAN) data link (NDL); and transmitting the multicast schedule to at least one other wireless device.

2 . The method of claim 1 , wherein the first wireless device is a service anchor for the service, and wherein the service anchor is a sole entity responsible for communicating the multicast schedule associated with the service.

3 . The method of claim 2 , wherein the first wireless device does not publish the service.

4 . The method of claim 1 , further comprising receiving a request from the at least one other wireless device to initiate the NDL for the service, wherein the multicast schedule is an immutable schedule.

5 . The method of claim 1 , wherein the service remains available for subscription by another wireless device based on an availability of the first wireless device to communicate the multicast schedule.

6 . The method of claim 1 , further comprising transmitting a message indicating that the multicast schedule is for propagation to other wireless devices requesting subscription to the service.

7 . The method of claim 6 , wherein the multicast schedule is associated with an instance of the service, and the multicast schedule is different from a set of multicast schedules associated with different instances of the service.

8 . The method of claim 1 , further comprising receiving a message that indicates the multicast schedule, wherein the multicast schedule is determined based on the received message.

9 . The method of claim 8 , wherein the message indicates that the multicast schedule is for propagation to other wireless devices requesting subscription to the service.

10 . The method of claim 1 , further comprising determining whether the service is a one-to-many or many-to-many service during service initialization.

11 . The method of claim 1 , wherein the multicast schedule is associated with a service identifier and a service instance identifier related to the service.

12 . The method of claim 1 , further comprising indicating from an application or a service layer whether the service is a one-to-many or a many-to-many service during service initialization through a data link initialization primitive.

13 . The method of claim 1 , further comprising transmitting a traffic announcement that includes a multicast identifier associated with the service, wherein the traffic announcement indicates that data will be transmitted for the service.

14 . A method of wireless communication by a first wireless device, comprising:
transmitting a message to a second wireless device to request a multicast schedule for communicating data associated with a service over a neighbor awareness networking (NAN) data link (NDL); and receiving a second message from the second wireless device based on the transmitted message, wherein the second message includes the multicast schedule for communicating data associated with the service over the NDL.

15 . The method of claim 14 , wherein the multicast schedule is inherited from a service provider of the service.

16 . The method of claim 14 , wherein the first wireless device is allowed to authenticate a third wireless device to join the NDL after successfully authenticating with the second wireless device to join the NDL.

17 . The method of claim 14 , further comprising receiving a common group key (CGK) after being authenticated by the second wireless device, wherein the CGK enables single authentication group authorization for encrypting and decrypting group-addressed traffic associated with the NDL.

18 . The method of claim 14 , wherein the multicast schedule is an immutable schedule.

19 . The method of claim 14 , wherein the second message indicates that the multicast schedule is for propagation to other wireless devices requesting subscription to the service.

20 . The method of claim 14 , wherein the second wireless device is a service anchor for the service, and the second wireless device is a sole entity responsible for communicating the multicast schedule associated with the service.

21 . The method of claim 14 , further comprising determining whether the service is a one-to-many or many-to-many service during service initialization.

22 . The method of claim 14 , further comprising indicating from an application or a service layer whether the service is a one-to-many or a many-to-many service during service initialization through a data link initialization primitive.

23 . The method of claim 14 , further comprising receiving a traffic announcement that includes a multicast identifier associated with a multicast service, wherein the traffic announcement indicates that data will be transmitted for the multicast service.

24 . The method of claim 23 , further comprising determining whether to enter a sleep mode based on the received traffic announcement.

25 . An apparatus for wireless communication, comprising:
means for determining a multicast schedule for communicating data associated with a service over a neighbor awareness networking (NAN) data link (NDL); and means for transmitting the multicast schedule to at least one other wireless device.

26 . The apparatus of claim 25 , wherein the apparatus is a service anchor for the service, and wherein the service anchor is a sole entity responsible for communicating the multicast schedule associated with the service.

27 . The apparatus of claim 26 , wherein the apparatus does not publish the service.

28 . The apparatus of claim 25 , further comprising means for receiving a request from the at least one other wireless device to initiate the NDL for the service, wherein the multicast schedule is an immutable schedule.

29 . The apparatus of claim 25 , wherein the service remains available for subscription by another wireless device based on an availability of the apparatus to communicate the multicast schedule.

30 . The apparatus of claim 25 , further comprising means for transmitting a message indicating that the multicast schedule is for propagation to other wireless devices requesting subscription to the service.

31 . The apparatus of claim 30 , wherein the multicast schedule is associated with an instance of the service, and the multicast schedule is different from a set of multicast schedules associated with different instances of the service.

32 . The apparatus of claim 25 , further comprising means for receiving a message that indicates the multicast schedule, wherein the multicast schedule is determined based on the received message.

33 . The apparatus of claim 32 , wherein the message indicates that the multicast schedule is for propagation to other wireless devices requesting subscription to the service.

34 . The apparatus of claim 25 , further comprising means for determining whether the service is a one-to-many or many-to-many service during service initialization.

35 . The apparatus of claim 25 , wherein the multicast schedule is associated with a service identifier and a service instance identifier related to the service.
