Method, program, and system for transferring data between a number of terminals that communicate via a common communication channel in a wireless network, and a wireless terminal
First Claim
1. A method of transferring data between a plurality of terminals that communicate via a common communication channel in a wireless network, each terminal being adapted to cover a coverage area, the method including:
- a step of sending a request-to-send data signal, RTS, from a first terminal to a second terminal located in a coverage area of the first terminal to advise the second terminal that the first terminal is requesting to send data;
a step of sending a clear-to-send data signal, CTS, from the second terminal to the first terminal to advise the first terminal that the second terminal is available to receive the data;
a step of receiving the clear-to-send data signal, CTS, by a third terminal in a coverage area of the second terminal, the third terminal not having received the request-to-send data signal, RTS, from the first terminal; and
upon receiving the clear-to-send data signal, a step of sending a request-to-receive data signal, RTR, from the third terminal, to advise other terminals located in a coverage area of the third terminal that the third terminal is available to receive data from one of such other terminals during transfer of data from the first terminal to the second terminal, wherein the other terminals are terminals other than the first terminal and the second terminal, andwherein the clear-to-send data signal, CTS, specifies the intended recipient of that signal, and the request-to-receive data signal, RTR, specified specifies the identity of the third terminal but no intended recipient of that signal.

Abstract
According to this method, each terminal is adapted to cover a coverage area. The method includes a step of sending a request-to-send data signal from a first terminal to a second terminal located in its coverage areas to advise the second terminal that the first terminal is requesting to send it data, and a step of sending a clear-to-send data signal to the first terminal to advise the first terminal that the second terminal is available to receive the data. The method further includes a step of a third terminal that has received the clear-to-send data signal and has not received the request-to-send signal sending a request-to-receive data signal to advise that it is available to receive data.

15. A non-transitory computer-readable medium storing a data transfer program, for transferring data between a plurality of terminals that communicate via a common communication channel in a wireless network, each terminal being adapted to cover a coverage area, the program comprising:
-
instructions for sending a request-to-send data signal, RTS, from a first terminal to a second terminal located in a coverage area of the first terminal to advise the second terminal that the first terminal is requesting to send data; instructions for sending a clear-to-send data signal, CTS, from the second terminal to the first terminal to advise the first terminal that the second terminal is available to receive the data; instructions for receiving the clear-to-send data signal, CTS, by a third terminal in a coverage area of the second terminal, the third terminal not having received the request-to-send data signal, RTS, from the first terminal; and upon receiving the clear-to-send data signal, instructions for sending a request-to-receive data signal, RTR, from the third terminal, to advise other terminals located in a coverage area of the third terminal that the third terminal is available to receive data from one of such other terminals during transfer of data from the first terminal to the second terminal, wherein the other terminals are terminals other than the first terminal and the second terminal, and wherein the clear-to-send data signal, CTS, specifies the intended recipient of that signal, and the request-to-receive data signal, RTR, specifies the identity of the third terminal but no intended recipient of that signal. - View Dependent Claims (16, 17)
