Abstract

In some examples, a method includes generating, at a first device, a paging message including an indication of whether the first device is available for a particular time period during which devices of a data link group of a neighbor aware network (NAN) are configured to operate in an active operating mode. The method also includes sending the message from the first device to one or more devices of the data link group of the NAN.

First claim

What is claimed is:

1 . A method of communication comprising:
generating, at a first device, a message including an indication of whether the first device is available during a particular time period during which devices of a data link group of a neighbor aware network (NAN) are configured to operate in an active operating mode; and sending the message from the first device to one or more devices of the data link group.

2 . The method of claim 1 , wherein the message comprises a service advertisement, wherein the message is sent during a discovery window of the NAN, and wherein the particular time period includes one or more periods of time between discovery windows of the NAN.

3 . The method of claim 1 , wherein the message comprises a paging message, wherein the message is sent during a paging window of the data link group.

4 . The method of claim 3 , wherein at least a portion of the particular time period is identified by multiple logical channels, and wherein each of the multiple logical channels corresponds to a communication channel and to at least one time period.

5 . The method of claim 1 , wherein the message is sent from the first device to the one or more devices during a paging window portion of a transmission window corresponding to a first logical channel referenced by an index of logical channels corresponding to the data link group of the NAN.

6 . The method of claim 5 , wherein the first logical channel corresponds to a basic communication channel or a supplemental communication channel of a plurality of supplemental communication channels referenced by the index of logical channels.

7 . The method of claim 6 , wherein the particular time period is identified by multiple logical channels, wherein the multiple logical channels represent communication channels and multiple time periods, and wherein an indication of the communication channels follows an indication of the supplemental communication channel in the index of logical channels.

8 . The method of claim 1 , wherein the indication identifies unavailability if the message includes a particular set of bits having a first value, and wherein the indication identifies availability if the particular set of bits has a second value that is different from the first value.

9 . An apparatus comprising:
a processor; and a memory coupled to the processor, wherein the memory stores instructions that are executable by the processor to perform operations comprising:
generating, at a first device, a message including an indication of whether the first device is available during a particular time period during which devices of a data link group of a neighbor aware network (NAN) are configured to operate in an active operating mode; and
initiating transmission of the message from the first device to one or more devices of the data link group.

10 . The apparatus of claim 9 , wherein the message comprises a paging message, wherein the message is transmitted during a paging window corresponding to the data link group, wherein the devices of the data link group are configured to operate in the active operating mode during the paging window.

11 . The apparatus of claim 9 , wherein the message comprises a service advertisement, wherein the message is transmitted during a discovery window corresponding to the NAN, wherein devices of the NAN are configured to operate in the active operating mode during the discovery window, the devices of the NAN including the devices of the data link group, and wherein the particular time period includes one or more periods of time between discovery windows of the NAN.

12 . The apparatus of claim 9 , wherein the indication identifies unavailability if the message includes a particular set of bits having a first value, and wherein the indication identifies availability if the particular set of bits has a second value that is different from the first value.

13 . The apparatus of claim 12 , wherein the particular set of bits includes a field or a particular bit.

14 . 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 a particular time period during which devices of the data link group are configured to operate in an active operating mode; and transitioning to a low-power operating mode during one or more transmission windows corresponding to the particular time period in response to determining that the first device is unavailable during the particular time period.

15 . The method of claim 14 , further comprising, if the second device is peered with other devices, determining that the other devices are unavailable during the particular time period prior to transitioning to the low-power operating mode.

16 . The method of claim 14 , wherein the message comprises a service advertisement, and wherein the particular time period includes a discovery window of the NAN.

17 . The method of claim 14 , wherein the message comprises a paging message, and wherein the particular time period includes a paging window of the data link group.

18 . The method of claim 17 , wherein at least a portion of the particular time period is identified by multiple logical channels, and wherein each of the multiple logical channels corresponds to a communication channel and at least one time period.

19 . The method of claim 18 , wherein the paging message is received during a paging window portion of a transmission window corresponding to a first logical channel referenced by an index of logical channels corresponding to the data link group.

20 . The method of claim 19 , wherein the first logical channel corresponds to a basic communication channel.

21 . The method of claim 19 , wherein the first logical channel corresponds to a supplemental communication channel of a plurality of supplemental communication channels referenced by the index of logical channels.

22 . The method of claim 14 , wherein the indication identifies unavailability if a particular bit has a first bit value, and wherein the indication indicates availability if the particular bit has a second bit value that is different from the first bit value.

23 . An apparatus comprising:
a processor; and a memory coupled to the processor, wherein the memory stores instructions that are executable by the processor to perform operations 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 for a particular time period during which devices of the data link group are configured to operate in an active operating mode; and
transitioning to a low-power operating mode during one or more transmission windows corresponding to the particular time period in response to determining that the first device is unavailable during the particular time period.

24 . The apparatus of claim 23 , wherein the operations further comprise, if the second device is peered with other devices, determining that the other devices are unavailable during the particular time period prior to transitioning to the low-power operating mode.

25 . The apparatus of claim 23 , wherein the message comprises a paging message.
