Abstract

A method for reduced overhead paging by an access point is described. The method includes assigning at least one paging identifier to at least one station. The method also includes partitioning a paging identifier space into paging identifier sets. The method further includes generating a paging message based on at least one of the paging identifier sets and the at least one paging identifier. The method additionally includes sending the paging message.

First claim

What is claimed is:

1. A method for wireless communication by a station, comprising:
preparing a power save polling (PS-POLL) request message comprising a token number, wherein the token number in the PS-POLL request message is the token number in one or more previous paging messages and is configured to indicate a correspondence between the PS-POLL request message and the one or more paging messages; and
transmitting the PS-POLL request message to an access point.

2. A method for wireless communication by an access point, comprising:
preparing a plurality of paging messages, wherein each of the plurality of paging messages is associated with at least one paging identifier of a plurality of paging identifiers and comprises a token number, wherein each of the plurality of paging identifiers is associated with at least one station of a set of stations;
transmitting at least one paging message to the at least one station;
receiving a power save polling (PS-POLL) request message from the at least one station, wherein the PS-POLL request message comprises the token number, wherein the token number in the PS-POLL request message is the token number in one or more previous paging messages and is configured to identify the PS-POLL request message as corresponding to the one or more paging messages; and
associating the one or more paging messages with the PS-POLL request message.

3. A station configured for wireless communication, comprising:
a processor;
memory in electronic communication with the processor;
instructions stored in the memory, the instructions being executable to:
prepare a power save polling (PS-POLL) request message comprising a token number, wherein the token number in the PS-POLL request message is the token number in one or more previous paging messages and is configured to indicate a correspondence between the PS-POLL request message and the one or more paging messages; and
transmit the PS-POLL request message to an access point.

4. An access point configured for wireless communication, comprising:
a processor;
memory in electronic communication with the processor;
instructions stored in the memory, the instructions being executable to:
prepare a plurality of paging messages, wherein each of the plurality of paging messages is associated with at least one paging identifier of a plurality of paging identifiers and comprises a token number, wherein each of the plurality of paging identifiers is associated with at least one station of a set of stations;
transmit at least one paging message to the at least one station;
receive a power save polling (PS-POLL) request message from the at least one station, wherein the PS-POLL request message comprises the token number, wherein the token number in the PS-POLL request message is the token number in one or more previous paging messages and is configured to identify the PS-POLL request message as corresponding to the one or more paging messages; and
associate the one or more paging messages with the PS-POLL request message.

5. An apparatus configured for wireless communication, comprising:
means for preparing a power save polling (PS-POLL) request message comprising a token number, wherein the token number in the PS-POLL request message is the token number in one or more previous paging messages and is configured to indicate a correspondence between the PS-POLL request message and the one or more paging messages; and
means for transmitting the PS-POLL request message to an access point.

6. An apparatus configured for wireless communication, comprising:
means for preparing a plurality of paging messages, wherein each of the plurality of paging messages is associated with at least one paging identifier of a plurality of paging identifiers and comprises a token number, wherein each of the plurality of paging identifiers is associated with at least one station of a set of stations;
means for transmitting at least one paging message to the at least one station;
means for receiving a power save polling (PS-POLL) request message from the at least one station, wherein the PS-POLL request message comprises the token number, wherein the token number in the PS-POLL request message is the token number in one or more previous paging messages and is configured to identify the PS-POLL request message as corresponding to the one or more paging messages; and
means for associating the one or more paging messages with the PS-POLL request message.

7. A computer-program product for wireless communication, the computer-program product comprising a non-transitory computer-readable medium having instructions thereon, the instructions being executable by a processor to cause a station to perform the steps of:
preparing a power save polling (PS-POLL) request message comprising a token number, wherein the token number in the PS-POLL request message is the token number in one or more previous paging messages and is configured to indicate a correspondence between the PS-POLL request message and the one or more paging messages; and
transmitting the PS-POLL request message to an access point.

8. A computer-program product for wireless communication, the computer-program product comprising a non-transitory computer-readable medium having instructions thereon, the instructions being executable by a processor to cause an access point to perform the steps of:
preparing a plurality of paging messages, wherein each of the plurality of paging messages is associated with at least one paging identifier of a plurality of paging identifiers and comprises a token number, wherein each of the plurality of paging identifiers is associated with at least one station of a set of stations;
transmitting at least one paging message to the at least one station;
receiving a power save polling (PS-POLL) request message from the at least one station, wherein the PS-POLL request message comprises the token number, wherein the token number in the PS-POLL request message corresponds to the token number in one or more previous paging messages and is configured to identify the PS-POLL request message as corresponding to the one or more paging messages; and
associating the one or more paging messages with the PS-POLL request message.
