Abstract

Official abstract text for this publication.

One or multiple bit restricted access window (RAW) end point determination within for single user, multiple user, multiple access, and/or MIMO wireless communications. A RAW is defined in which only devices of the particular class (e.g., low power class, Z class, smart meter station (SMSTA) class, etc.) are allowed access to the communication medium. Indication of the end of such a RAW may be included within one or more bits set within a signal field (SIG) field of a framer packet generated by a given device within the system and transmitted to one or more other devices. After completion of the RAW, other respective devices of at least one other type of class may be provided access to the communication medium. The manner of access to the communication media outside of the RAW may be varied (e.g., scheduled, based on carrier sense multiple access/collision avoidance (CSMA/CA), etc.).

First claim

Opening claim text (preview).

What is claimed is: 1. A wireless communication device comprising: a communication interface; and a processor, the processor and the communication interface configured to: generate a frame that includes a field having at least one bit set therein to indicate restricted access for at least one other wireless communication device and no other wireless communication device to a communication medium during at least one time period; transmit the frame to the at least one other wir…
