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 manner facilitating exclusion of the allocated AID from a traffic indication map (TIM) in a beacon signal transmitted by the AP based upon the indication of the at least one STA'"'"' s LPMA capabilities; and

    assigning a wakeup time to the at least one STA selected to decrease collisions with PS-Poll transmissions by other LPMA STAs associated with the AP.
