First Claim
Patent Images
1. A method of communicating information over one or more wireless channels in a network, comprising the steps of:
- controlling channel access among wireless stations by dividing channel time into one or more superframes;
providing one or more schedules in each superframe for communicating information, wherein each schedule comprises one or more channel time blocks (CTBs) including one or more reserved CTBs for communication of packets of information over a channel; and
communicating packets of information over the channel during the reserved CTBs according to each schedule.

Abstract
A channel time allocation and access control process for communication in wireless networks is provided. The channel time is divided into channel time blocks (CTBs), including one or more reserved CTBs and one or more unreserved CTBs. Schedules are implemented, wherein one or more periodic, equal-sized CTBs are reserved for isochronous streams. Dynamic CTB extension and truncation allow flexible channel time allocation.

30. A coordinator for managing communication of information over one or more wireless channels in a network, comprising:
-
a controller configured for receiving a bandwidth request from a source wireless station for transmission of information, and determining channel bandwidth availability; and
a scheduler configured for allocating available channel bandwidth by dividing channel time into one or more superframes, each superframe including one or more schedules comprising one or more channel time blocks (CTBs) that include one or more reserved CTBs for communication of packets of information over a channel. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)

53. A wireless station for communication of information over one or more wireless channels in a network, comprising:
-
a controller module configured for requesting reservation of available channel bandwidth from a coordinator for transmission of information; and
a communication module configured for communication of packets of information over a channel according to one or more schedules provided by the coordinator, wherein each schedule allocates available channel bandwidth by dividing channel time into one or more superframes, each superframe including one or more schedules comprising one or more channel time blocks (CTBs) that include one or more reserved CTBs for communication of packets of information over the channel. - View Dependent Claims (54, 55, 56, 57, 58, 59, 60, 61, 62, 63)
