Abstract

Systems, methods, and devices for communicating data in a wireless communications network are described herein. In some aspects, a station includes a first receiver and a low power circuit including a second receiver. The second receiver may be configured to consume less power than the first receiver. The second receiver receives short paging messages from another wireless device, such as an access point. The paging messages may trigger transitions of the first receiver from inactive doze or sleep states to active awake states based on Traffic Information Maps. Once in the awake state, the first receiver receives messages. This enables the first receiver to reduce the time spent awake, thereby reducing power consumption. A system and method for identifying and managing paging modes is described herein.

8. The apparatus of claim 1, wherein the plurality of types of paging messages comprises an NDP message.

9. The apparatus of claim 1, wherein the plurality of types of paging messages comprises an encoded on-off keyed message.

10. The apparatus of claim 1, wherein the plurality of types of paging messages comprises an orthogonal frequency division multiplexed message.

11. An apparatus for wireless communication, comprising:

a transmitter configured to transmit a request for a paging message, the paging message being one of a plurality of types of paging messages; and

a receiver configured to receive the paging message.

12. The apparatus of claim 11, wherein the request includes an indication of a transmission rate that is less than a maximum rate of the receiver.

13. The apparatus of claim 11, wherein the request identifies a minimum time offset from reception of a beacon, and wherein the receiver is configured to receive the paging message at the minimum time offset.

14. The apparatus of claim 11, wherein the request identifies a maximum time offset from reception of a beacon, and wherein the receiver is configured to receive the paging message at the maximum time offset.

15. A method of wireless communication, comprising:

receiving a request for a paging message, the paging message being one of a plurality of types of paging messages;

generating the paging message; and

transmitting the paging message.

16. The method of claim 15, further comprising sending a response to the request for the paging message.

17. The method of claim 16, wherein the response indicates acceptance of at least one of the request, a length of the paging message, or a timing of transmission of the paging message.

18. The method of claim 16, wherein the response is configured to include at least one group identifier for at least one recipient of the paging message.

19. The method of claim 15, wherein transmitting the paging message occurs at an integer multiple of a period for transmitting beacons.

20. The method of claim 15, wherein transmitting the paging message is at a rate identified by the request, wherein the rate identified by the request is at a higher transmission rate than a beacon transmission rate.

21. The method of claim 15, wherein the plurality of types of paging messages comprises a TIM broadcast message.

22. The method of claim 15, wherein the plurality of types of paging messages comprises an NDP message.

23. The method of claim 15, wherein the plurality of types of paging messages comprises an encoded on-off keyed message.

24. The method of claim 15, wherein the plurality of types of paging messages comprises an orthogonal frequency division multiplexed message.

25. A method of wireless communication, comprising:
