Abstract
Method, apparatus, and computer program product embodiments improve power saving in network environments. An example method embodiment comprises: generating in an access point device, a traffic indication map comprising a page bitmap field, a page control field, one or more block bitmap fields, and one or more sub-block bitmaps indicating wireless client devices having buffered data in the access point device available for them; and periodically broadcasting the traffic indication map in a beacon frame to the wireless client devices.
Claims26
A method, comprising:
- receiving by a wireless client device, a traffic indication map in a beacon frame from an access point, the traffic indication map comprising a page bitmap field, a page control field, and one or more block bitmap fields, indicating there is buffered data available in the access point device for one or more wireless client devices;
- decoding by the wireless client device, the traffic indication map;
- and
- determining by the wireless client device, that there is buffered data available in the access point device for the wireless client device.
A method, comprising:
- generating in an access point device, a traffic indication map comprising a page bitmap field, a page control field, and one or more block bitmap fields, indicating wireless client devices having buffered data in the access point device available for them;
- and
- periodically broadcasting the traffic indication map in a beacon frame to the wireless client devices.
An apparatus, comprising:
- at least one processor;
- at least one memory including computer program code;
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
- receive a traffic indication map in a beacon frame from an access point, the traffic indication map comprising a page bitmap field, a page control field, and one or more block bitmap fields, indicating there is buffered data available in the access point device for one or more wireless client devices;
- decode the traffic indication map;
- and
- determine that there is buffered data available in the access point device for the apparatus.
An apparatus, comprising:
- at least one processor;
- at least one memory including computer program code;
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
- generate a traffic indication map comprising a page bitmap field, a page control field, and one or more block bitmap fields, indicating wireless client devices having buffered data in the apparatus available for them;
- and
- periodically broadcasting the traffic indication map in a beacon frame to the wireless client devices.
A computer program product comprising computer executable program code recorded on a computer readable, non-transitory storage medium, the computer executable program code comprising:
- code for receiving by a wireless client device, a traffic indication map in a beacon frame from an access point, the traffic indication map comprising a page bitmap field, a page control field, and one or more block bitmap fields, indicating there is buffered data available in the access point device for one or more wireless client devices;
- code for decoding by the wireless client device, the traffic indication map;
- and
- code for determining by the wireless client device, that there is buffered data available in the access point device for the wireless client device.
A computer program product comprising computer executable program code recorded on a computer readable, non-transitory storage medium, the computer executable program code comprising:
- code for generating in an access point device, a traffic indication map comprising a page bitmap field, a page control field, and one or more block bitmap fields, indicating wireless client devices having buffered data in the access point device available for them;
- and
- code for periodically broadcasting the traffic indication map in a beacon frame to the wireless client devices.
