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 schedule for communicating data in a NAN network. The apparatus is configured to communicate data over a data link within the NAN network based on the determined schedule.

First claim

What is claimed is:

1 . A method of wireless communication by a wireless device, comprising:
determining a schedule for communicating data in a neighbor awareness networking (NAN) network; and communicating data over a data link within the NAN network based on the determined schedule.

2 . The method of claim 1 , further comprising:
transmitting a first availability information to a second wireless device, the first availability information comprising a first schedule at which the wireless device is available on a first channel and a first indicator indicating whether the wireless device is available on any channel of a set of channels; and receiving a second availability information from the second wireless device based on the transmitted first availability information, the second availability information comprising a second schedule at which the second wireless device is available on a second channel and a second indicator indicating whether the second wireless device is available on any channel of the set of channels.

3 . The method of claim 2 , wherein the second schedule is the same as the first schedule or the second schedule is different from the first schedule.

4 . The method of claim 2 , wherein the schedule is determined based on the transmitted first availability information and the received second availability information.

5 . The method of claim 4 , wherein the determining the schedule comprises determining that the wireless device is unavailable for communication during the second schedule, and wherein the method further comprises transmitting a third availability information to the second wireless device, the third availability information comprising a third schedule at which the wireless device is available on a third channel and a third indicator indicating whether the wireless device is available on any channel of a set of channels.

6 . The method of claim 4 , further comprising transmitting a schedule confirmation message that indicates the wireless device is available for communication based on the received second availability information, wherein the schedule for the data link within the NAN network is based on the received second availability information, and wherein the data is communicated after transmitting the schedule confirmation message.

7 . The method of claim 2 , wherein the first availability information further includes a data link identifier identifying the data link.

8 . The method of claim 1 , further comprising:
receiving a data link setup solicitation message; transmitting availability information to a second wireless device, the availability information comprising a first schedule at which the wireless device is available on a channel and an indicator indicating whether the wireless device is available on any channel of a set of channels, wherein the availability information is transmitted based on the received data link setup solicitation message; and receiving a data link schedule based on the transmitted availability information, wherein the schedule is determined based on the received data link schedule.

9 . The method of claim 1 , further comprising:
receiving a data link schedule, wherein the data link schedule comprises one or more logical channels, each of the one or more logical channels comprising a respective time block duration and a respective time block periodicity, wherein the determining the schedule is based on the received data link schedule.

10 . The method of claim 9 , wherein the received data link schedule is non-negotiable and the schedule is determined based on the received data link schedule if the wireless device is available for communications during more than half of the received data link schedule.

11 . The method of claim 1 , wherein the data is communicated based on a lifetime associated with the data link, wherein the lifetime provides a boundary for schedule transition.

12 . The method of claim 11 , wherein the lifetime associated with the data link is extended by a period of time to enable data communication.

13 . The method of claim 1 , wherein the data link is associated with one or more NAN data paths (NDPs), each NDP is associated with a session of a service between the wireless device and a second wireless device, and each NDP is associated with the same determined schedule.

14 . The method of claim 13 , wherein the data link is associated with a data link identifier, and each NDP is associated with an NDP identifier.

15 . The method of claim 13 , wherein each NDP of the one or more NDPs has a quality of service and security requirements that are different from other NDPs of the one or more NDPs.

16 . A method of wireless communication by a first wireless device, comprising:
determining a schedule for communicating data over a data link within a neighbor awareness networking (NAN) network; and communicating data with a second wireless device based on the determined schedule.

17 . The method of claim 16 , further comprising:
receiving a first availability information from a second wireless device, the first availability information comprising a first schedule at which the second wireless device is available on a first channel and a first indicator indicating whether the second wireless device is available on any channel of a set of channels; and transmitting a second availability information to the second wireless device based on the received first availability information, the second availability information comprising a second schedule at which the wireless device is available on a second channel and a second indicator indicating whether the wireless device is available on any channel of the set of channels.

18 . The method of claim 17 , wherein the determining the schedule comprises:
determining whether the wireless device is unavailable for communication based on the first availability information, wherein the second availability information is determined based on the first availability information.

19 . The method of claim 17 , further comprising receiving a schedule confirmation message that indicates the second wireless device is available for communication based on the transmitted second availability information, wherein the schedule for the data link within the NAN network is based on the received second availability information, and wherein the data is communicated after receiving the schedule confirmation message.

20 . The method of claim 16 , further comprising:
transmitting a data link setup solicitation message; receiving availability information from at least one other device, the availability information including a schedule at which each of the at least one other device is available on a particular channel and an indicator indicating whether each of the at least one other device is available on any channel of a set of channels, wherein the availability information is received based on the data link setup solicitation message; and transmitting the determined schedule for communicating data, wherein the determined schedule for communicating data is based on the received availability information from the at least one other device.

21 . The method of claim 16 , wherein the determining the schedule comprises determining one or more logical channels, each of the one or more logical channels comprising a respective time block duration and a respective time block periodicity, and the method further comprising transmitting the determined schedule that indicat
