Abstract
Single radio retransmission with a half duplex radio accomplished using Time Division Duplexing to alternate between transmit and receive cycles of a retransmission radio. This allows a single half duplex radio to function as the retransmission radio. The retransmission half duplex radio may be utilized in a communication system comprised of a plurality of remote units to increase communication range and area coverage and perform channel conversion.
Claims34
A half duplex radio for facilitating communication of data between two remote terminals using Time Division Duplexing where channel resources are divided in time into fixed size frames comprising:
- a receiver means for receiving data from a remote transmitting terminal in a receive segment of said fixed size frame;
- a buffering means for storing the data said buffering means comprising at least an input pointer, an output pointer, a counter and a control means;
- and,
- a transmitter means for transmitting said data to a remote receiving terminal in a transmit segment of said fixed size frame.
A method of retransmission of data using Time Division Duplexing in half duplex radios where channel resources are divided in time into fixed size frames comprising the steps of:
- (a) transmitting said data from a first half duplex radio in a transmit segment of said fixed size frame;
- (b) receiving the data from said first half duplex radio by a second half duplex radio in a receive segment of said fixed size frame;
- (c) buffering the data in said second half duplex radio;
- (d) transmitting the data by said second half duplex radio in a transmit segment of said fixed size frame;
- and,
- (e) receiving said data by a third half duplex radio in a receive segment of said fixed size frame.
A data retransmission system using Time Division Duplexing where channel resources are divided in time into fixed size frames comprising:
- a first radio wherein said radio transmits data to a half duplex radio in a transmit segment of said fixed size frame;
- said half duplex radio receiving the data from said first radio in a receive segment of said fixed frame, said half duplex radio further buffering the data and retransmitting the data to a second radio in a transmit segment of said fixed frame;
- and,
- said second radio receiving the data from said half duplex radio in a receive segment of said fixed frame.
A method of extending the range of communicated data using Time Division Duplexing where channel resources are divided in time into fixed size frames comprising the steps of:
- (a) transmitting said data from a first radio in a transmit segment of said fixed size frame;
- (b) receiving said data from the first radio by a half duplex radio in a receive segment of said fixed size frame;
- (c) buffering the data in said half duplex radio;
- (d) transmitting the data by said half duplex radio in a transmit segment of said fixed size frame;
- and,
- (e) receiving said data by a second radio in a receive segment of said fixed size frame.
A method of channel conversion of communicated data using Time Division Duplexing where channel resources are divided in time into fixed size frames comprising the steps of:
- (a) transmitting said data from a first radio in a transmit segment of said fixed size frame;
- (b) scanning at least two different channels by a half duplex radio until data is received from one of at least two different channels;
- (c) receiving said data from the first radio by said half duplex radio in a receive segment of said fixed size frame;
- (d) buffering the data in said half duplex radio;
- (e) transmitting the data by said half duplex radio in a transmit segment of said fixed size frame;
- and,
- (f) receiving said data by a second radio in a receive segment of said fixed size frame.
A system of channel conversion of communicated data using Time Division Duplexing where channel resources are divided in time into fixed size frames comprising:
- a first radio transmitting data to a half duplex radio in a transmit segment of said fixed frame;
- said half duplex radio receiving the data in a receive segment of said fixed frame, said half duplex radio further buffering said data and retransmitting the data to a second radio in a transmit segment of said fixed frame;
- and,
- said second radio receiving the data from the half duplex radio in a receive segment of said fixed frame.
