Medium access control layer that encapsulates data from a plurality of received data units into a plurality of independently transmittable blocks

摘要

A method of operating in a network in which a plurality of stations communicate over a shared medium, comprising providing a physical layer (e.g., PHY) for handling physical communication over the shared medium; providing a high level layer (e.g., PAL) that receives data from the station and supplies high level data units (e.g., MSDUs) for transmission over the medium; providing a MAC layer that receives the high level data units from the high level layer and supplies low level data units (e.g., MPDUs) to the physical layer; at the MAC layer, encapsulating content from a plurality of the high level data units; dividing the encapsulated content into a plurality of pieces (e.g., segments) with each piece capable of being independently retransmitted; and supplying low level data units containing one or more of the plurality of pieces.

主权项

1. A method of a station for operating in a network, the method comprising:
receiving, at a media access control (MAC) layer, a plurality of high level data units from a high level layer; encapsulating content from the plurality of high level data units into sub-frames; grouping a plurality of the sub-frames that belong to a same session as a stream of sub-frames; dividing the stream of sub-frames into a plurality of segments, each segment forming part of a physical layer (PHY) block; generating a low level data unit for transmission by a physical layer, the low level data unit containing one or more PHY blocks; and providing the low level data unit from the MAC layer to the physical layer for transmission over a shared communications medium.
