One or multiple bit restricted access window (RAW) end point determination within for single user, multiple user, multiple access, and/or MIMO wireless communications

摘要

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.).

主权项

1. An apparatus comprising:
a baseband processing module configured to generate a frame that includes a signal field (SIG) that includes at least one bit therein set to indicate a restricted access window (RAW) corresponding to a time period in which at least one wireless communication device of a first class has access to a communication medium within a communication system that includes a plurality of wireless communication devices; and a radio configured to transmit the frame or a signal corresponding to the frame to at least one of the plurality of wireless communication devices, wherein: the plurality of wireless communication devices includes the at least one wireless communication device of the first class and at least one communication device of a second class; after an end of the RAW, the at least one wireless communication device of the second class has the access to the communication medium; during the RAW, no wireless communication device of the second class has the access to the communication medium and only the at least one wireless communication device of the first class has the access to the communication medium; and outside of the RAW, the at least one communication device of the second class and the at least one wireless communication device of the first class has the access to the communication medium based on carrier sense multiple access/collision avoidance (CSMA/CA).
