System and method for wireless communication of uncompressed video having a link control and bandwidth reservation scheme for control/management message exchanges and asynchronous traffic
First Claim
1. A method of performing medium access control in a system for wireless communication of uncompressed video, wherein the system comprises a high rate channel and a low rate channel, the method comprising:
- receiving a control initiation request message over the low rate channel from a client device;
determining at least one time slot for communication of control messages associated with the client device within a superframe period of a predetermined length; and
transmitting a message over the low rate channel containing information identifying the at least one determined time slot.

Abstract
A system and method for performing medium access control in a system for wireless communication of uncompressed video is disclosed. In one aspect, the method includes communicating a control initiation request message during a contention based period of a superframe period. The control initiation request message contains information allowing a device coordinator to determine a reserved time slot for communication of the requested message exchange. The requested message exchange is then performed in a non-contentious environment, thereby limiting collisions of contention based messages. The control initiation procedure and subsequent message exchanges take place on a low-rate channel. Transmission on the low-rate channel is time division duplexed with a high-rate channel, where transmission at any one time can take place on either the high-rate or the low-rate channel.

33. A system for communicating uncompressed video data over a wireless communication link, the wireless communication link including a high rate channel associated with a bandwidth capable of supporting transmission of the uncompressed video data, and a low rate channel associated with a bandwidth smaller than the bandwidth of the high rate channel, wherein frequency bands of the low rate channel and the high rate channel at least partially overlap, the system comprising:
-
a device coordinator comprising; a receiver to receive a control initiation request message over the low rate channel during a first period of a superframe period of a predetermined length, a link controller to determine a time slot within a second portion of the superframe period for communication of control messages over the low rate channel, and a transmitter to transmit a response message over the low rate channel containing information identifying the determined time slot; and a client device comprising; a transmitter to transmit the control initiation request message over the low rate channel, and a receiver to monitor the low rate channel and to receive the response message, wherein the transmitter is further configured to transmit a control message during the identified time slot of one or more subsequent superframes in response to receiving the response message containing the reserved time slot information.
