Wireless repeating method and wireless repeating unit
First Claim
1. A wireless repeating method, where a wireless communication line is divided with respect to time using a first sub-frame comprising a plurality of time slots and a second sub-frame following said first sub-frame and comprising the same number of time slots as said first sub-frame, for relaying a wireless signal between a first wireless device for transmitting first information using a time slot of said first sub-frame and receiving second information transmitted at a time slot of said second sub-frame corresponding to said transmission time slot and a second wireless device for receiving said first information transmitted from said first wireless device and transmitting said second information to said first wireless device via a wireless repeating unit, comprising the steps of:
- (a) allotting Mth time slots of said first and second sub-frames to said first wireless device in such a manner that said first wireless device transmits said first information at said Mth time slot of said first sub-frame and receives said second information at said Mth time slot of said second sub-frame;
(b) allotting Nth time slots of said first and second sub-frames that are different from said Mth time slots to said second wireless device in such a manner that said second wireless device transmits said first information at said Nth time slot of said first sub-frame and receives said second information at said Nth time slot of said second sub-frame;
(c) storing said first information transmitted from said first wireless device at said Mth time slot of said first sub-frame and said second information transmitted from said second wireless device at said Nth time slot of said first sub-frame at said wireless repeating unit; and
(d) reading said held first information and outputting said first information at said Nth time slot of said second sub-frame and reading said held second information and outputting said second information at said Mth time slot of said second sub-frame.

Abstract
The object of the present invention is to provide a simple wireless repeating method and a repeater suitable for application to Time Division Multiple Access-Time Division Duplex communication methods. Transmission data transmitted from a base station and a mobile station at different time slots of a frequency for call channel use is received at a call channel receiver, analyzed every time slot at a frame analyzer and stored at a storage part. The data stored at the storage part is then read by a frame configuration unit on the timing of time slots Tb1 and Tb2 allotted to the base station and the mobile station prior to transmission and transmitted from a transmitter at the frequency for call channel use. The mobile station can therefore make calls with the base station with the same procedure regardless of whether or not a repeater is present or absent.

5. A wireless repeating system, where a wireless communication line is divided with respect to time using a first sub-frame comprising a plurality of time slots and a second sub-frame following said first sub-frame and comprising the same number of time slots as said first sub-frame, with a wireless signal being relayed between a first wireless device for transmitting first information using a time slot of said first sub-frame and receiving second information transmitted at a time slot of said second sub-frame corresponding to said transmission time slot and a second wireless device for receiving said first information transmitted from said first wireless device and transmitting said second information to said first wireless device via a wireless repeating unit,
wherein said first wireless device is allotted with Mth time slots of said first and second sub-frames in such a manner as to transmit said first information at said Mth time slot of said first sub-frame and receive said second information at said Mth time slot of said second sub-frame; -
said second wireless device is allotted with Nth time slots of said first and second sub-frames that are different from said Mth time slots in such a manner as to transmit said first information at said Nth time slot of said first sub-frame and receive said second information at said Nth time slot of said second sub-frame; and said wireless repeating unit is for storing said first information transmitted from said first wireless device at said Mth time slot of said first sub-frame and said second information transmitted from said second wireless device at said Nth time slot of said first sub-frame and reading said held first information and outputting said first information at said Nth time slot of said second sub-frame and reading said held second information and outputting said second information at said Mth time slot of said second sub-frame. - View Dependent Claims (6, 7, 8)

9. A repeater, where a wireless communication line is divided with respect to time using a first sub-frame comprising a plurality of time slots and a second sub-frame following said first sub-frame and comprising the same number of time slots as said first sub-frame, for relaying a wireless signal between a first wireless device for transmitting first information using a time slot of said first sub-frame and receiving second information transmitted at a time slot of said second sub-frame corresponding to said transmission time slot and a second wireless device for receiving said first information transmitted from said first wireless device and transmitting said second information to said first wireless device, said repeater comprising:
-
a receiver for receiving information of said first sub-frame of said wireless communication line; a storage part for storing said first information, of information received at said receiver, transmitted from said first wireless device at an Mth time slot of said first sub-frame and said second information transmitted from said second wireless device at an Nth (where N≠
M) time slot of said first sub-frame;a transmission controller for reading said first information stored in said storage part and outputting said first information at said Nth time slot of said second sub-frame and reading out said second information stored in said storage part and outputting said second information at said Mth time slot of said second sub-frame; and a transmitter for transmitting said first and second information outputted from said transmission controller via said wireless communication line. - View Dependent Claims (10, 11, 12)
