Abstract

Enhanced low power medium access (LPMA) processes involve the enhanced LPMA STA indicating low power capabilities during association and being allocated an AID. The AID(s) for one or a group of enhanced LPMA STA(s) are included in one TIM sent during a different BEACON interval than the AID(s) for another or another group of enhanced LPMA STA(s). In addition, or alternatively, the AID(s) for enhanced LPMA STA(s) are located at an edge of the AID set within a TIM, a portion of the TIM that may be easily truncated and therefore not sent. The enhanced LPMA STAs and associated access point negotiate unique offset and sleepinterval periods for polling or data uplink by the enhanced LPMA STAs.

First claim

What is claimed is:

1. A method, comprising:
during association of at least one station (STA) with an access point (AP), receiving at the AP an indication of low power medium access (LPMA) capabilities for the at least one STA indicating that the respective STA is configured to poll the AP using a Power-Save Poll (PS-Poll) and does not wake to receive each beacon signal transmitted by the AP;
allocating an association identification (AID) to the at least one STA at the AP in a m…
