Short-range radio communications system and method of use
First Claim
1. A method for simultaneously communicating voice information and data between a first terminal and a second terminal in a short-range wireless communications system, comprising the steps of:
- defining a repetitive frame of predetermined time duration;
dividing the repetitive frame into a plurality of time slots;
in a first time slot of a first said frame, transmitting from one of the first and second terminals directly to the other of the first and second terminals a first quantity of voice information produced at the one terminal in response to a voice stimulus provided at the one terminal by a voice-sending party operating the one terminal, and the other terminal receiving the first quantity of voice information directly from the one terminal and reproducing therefrom the voice stimulus to be heard by a voice-receiving party operating the other terminal; and
communicating data directly between the first and second terminals simultaneously with the communication of voice information directly between the first and second terminals, including, in a second time slot of said first frame, transmitting a first quantity of data from one of the first and second terminals directly to the other of the first and second terminals, and the other terminal receiving the first quantity of data directly from the one terminal.

Abstract
A short-range wireless radio communications system is provided that can carry data, voice, or data and voice traffic simultaneously. The band is divided into a plurality of channels or hops, and a burst composed of either voice information, data information, or a combination of data and voice information is transmitted during one of the hops. The system operates preferably in a simplex mode, but full duplex operation can also be employed. The present system can also be operated in a cellular, TDMA system. A multiple time slot method is employed whereby one time slot can carry data and another time slot can carry voice information.

13. A method for retransmitting erroneous voice information and data between a first terminal and a second terminal in a short-range wireless radio communications system, comprising the steps of:
-
defining a repetitive frame of predetermined time duration; dividing the repetitive frame into a plurality of time slots; in a first time slot of a first said frame, transmitting from the first terminal directly to the second terminal a first quantity of voice information produced at the first terminal in response to a voice stimulus provided at the first terminal by a voice-sending party operating the first terminal, the second terminal receiving the first quantity of voice information directly from the first terminal and reproducing therefrom the voice stimulus to be heard by a voice-receiving party operating the second terminal; communicating data directly between the first and second terminals simultaneously with the communication of voice information directly between the first and second terminals, including, in a second time slot of said first frame, transmitting a first quantity of data from the first terminal directly to the second terminal, the second terminal receiving the first quantity of data directly from the first terminal; upon detection at the second terminal of an erroneous payload in at least one of said first quantity of voice information and said first quantity of data, transmitting an error indication and said payload from the second terminal to the first terminal in a third time slot of said first time frame; and retransmitting said at least one of said first quantity of voice information and said first quantity of data in a time slot of a second said frame.

14. A method for permitting a first terminal to simultaneously communicate with a plurality of other terminals in a short-range wireless radio communications system, comprising the steps of:
-
defining a repetitive frame of predetermined time duration; dividing the repetitive frame into a plurality of time slots; selecting a first time slot of a first said frame for the first terminal to transmit data directly to one of the other terminals; selecting a second time slot of said first frame for the first terminal to receive directly from one of the other terminals voice information that is produced at the one other terminal in response to a voice stimulus which is provided at the one other terminal by a voice-sending party operating the one other terminal, and which voice stimulus is to be reproduced from the voice information by the first terminal and heard by a voice-receiving party operating the first terminal; selecting said second time slot independently of said first time slot; selecting a first frequency for transmitting in said first time slot; selecting a second frequency for receiving in said second time slot; and selecting said second frequency independently of said first frequency. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. A terminal for communicating with other terminals in a short-range wireless radio communications system, comprising:
-
a resource allocation section operable to define a repetitive frame of predetermined time duration and divide the repetitive frame into a plurality of time slots; a transmitting section operable to transmit a first quantity of data directly to one of the other terminals in a first time slot of a first said frame; and a receiving section operable to receive directly from one of the other terminals in a second time slot of said first frame a first quantity of voice information produced at the one other terminal in response to a voice stimulus provided at the one other terminal by a voice-sending party operating the one other terminal, and said receiving section further operable to reproduce from the first quantity of voice information the voice stimulus to be heard by a voice-receiving party operating the terminal. - View Dependent Claims (24, 25, 26, 27, 28, 29)
