Multiple mode data communication system and method and forward and/or reverse link control channel structure

A method of communicating data between a wireless unit and at least one base station comprising the steps of:

• receiving a sequence of bits on a control channel from said wireless unit to indicate operation in an autonomous mode or a scheduling mode;
• and
• receiving data in an autonomous mode where data is received from said wireless unit autonomously after said wireless unit has switched from a scheduling mode and after a request is made by said wireless unit for transmission of data.

A method of communicating data between a wireless unit and a plurality of base stations comprising the steps of:

• receiving a first schedule grant from a first base station of said plurality of base stations and a second schedule grant, which is independent of said first schedule grant, from a second base station of said plurality of base stations for transmission of said data from said wireless unit;
• and
• transmitting said data by said wireless unit according to said first schedule grant and receiving an acknowledgment from at least said second base station that said data was received.

A method of receiving data between a wireless unit and a plurality of base stations, said method comprising the steps of:

• receiving data transmitted by a wireless unit using an autonomous mode established for transmitting data autonomously to at least a first base station of said plurality of base stations;
• and
• receiving data transmitted by said wireless unit using a scheduling mode where data is transmitted after a request is made for transmission of data, which is independent from said the autonomous mode, established for transmitting data between said wireless unit and at least a second base station of said plurality of base stations.

A wireless unit for use in communicating data with at least one base station, said wireless unit comprising:

• transmission circuitry configured to transmit according to an autonomous mode where data is transmitted autonomously after said wireless unit switches from a scheduling mode after a request for transmission of data is made by said wireless unit, said transmission circuitry further configured to transmit a sequence of bits on a control channel to said base station to indicate operation in said autonomous mode.
