Methods and arrangements to determine station assignments to restricted access windows in wireless networks

摘要

Logic may implement a restricted access window association scheme that uses information provided in traffic indication map (TIM) bitmap and restricted access window (RAW) parameter set (PS) to determine stations associated with RAWs. The TIM information element (IE) may comprise a bitmap indicating paged and unpaged stations. The RAW PS IE may comprise a range of station association identifiers (AIDs) and possibly other station selection data. Logic may determine a range of stations associated with a RAW based upon AIDs for the first and last stations in the range based upon a position for the station in the TIM bitmap. And the range of stations associated with a RAW may be independent of block associations of the first and last stations in the TIM bitmap.

主权项

1. An apparatus comprising:
circuitry to access restricted access window (RAW) group fields of a RAW parameter set element (RPS element), the fields comprising:
a Page index, a RAW Start Association Identifier (AID), and a RAW End AID, wherein:the Page index, the RAW start AID, and the RAW end AID to collectively identify a group of one or more stations permitted to access a medium during a RAW,the Page index is to identify a page index for the group of one or more stations,the RAW start AID comprises a portion of an AID of a first station in the group of one or more stations and the first station to have a corresponding RAW, andthe RAW end AID field comprises a portion of an AID of a second station in the group of one or more stations and the second station to have a corresponding RAW; and circuitry to access the medium based at least in part on the Page index, the RAW start AID, and the RAW end AID.
