TDD repeater for a wireless network and method for operating said repeater
First Claim
1. A time-division duplex (TDD) repeater system comprising:
- a master unit configured for communicating with a base station of a wireless network;
at least one remote unit configured for communicating with a terminal device and located away from the master unit;
a waveguide connecting the remote unit with the master unit for transmitting communication signals in an uplink direction and in a downlink direction;
the master unit configured for exchanging uplink and downlink communication signals with the at least one remote unit;
the at least one remote unit having a defined uplink path and a separate defined downlink path therein and including a switch coupled with each of the defined paths for changing direction of the signal transmission in the at least one remote unit between transmission in the uplink direction and transmission in the downlink direction;
a control unit located in the at least one remote unit and configured for processing a signal portion of the signals in at least one of the uplink direction and the downlink direction, the control unit using the processed signal portion for determining the direction of the repeater system signal transmission and for controlling the remote unit switch and the signal transmission direction;
wherein the signal portion is derived from a radio-frequency (RF) control signal generated by the TDD repeater system and wherein the control unit drives the remote unit switch at a frequency determined from the processed signal portion.

Abstract
A repeater (1) particularly suitable for a time-division duplex transmission of communication signals is provided. The repeater (1) comprises a master unit (2) for communicating with a base station (3) of a wireless network, at least one remote unit (4) for communicating with a network terminal, as well as a waveguide (11) connecting the remote unit (4) with the master unit (2) for transmitting the communication signals in an uplink direction (6) from the remote unit (4) to the master unit (2) and in a downlink direction (5) from the master unit (2) to the remote unit (4). Both the master unit (2) and the remote unit (4) comprise one switch (19, 20) each for changing over the signal transmission between uplink direction (6) and downlink direction (5). Both switches (19, 20) are selected by a synchronizing unit (21) arranged in the master unit (2), the synchronizing unit (21) being designed for determining a clock pulsing from the communication signal fed to the master unit (2)—in particular from the base station (3)—and for supplying a control signal corresponding to this clock pulsing to the switches (19, 20).

11. A method for time-division duplex (TDD) signal repeating comprising:
-
communicating communication signals with a master unit from a base station of a wireless network; transmitting the communication signals with a waveguide between the master unit and at least one remote unit including selectively transmitting the communication signals in an uplink direction and in a downlink direction; in the at least one remote unit, having a defined uplink path and a separate defined downlink path, using a switch coupled with each of the defined paths for changing direction of the signal transmission between transmission in the uplink direction and transmission in the downlink direction; in the at least one remote unit, processing a signal portion of the signals in at least one of the uplink direction and the downlink direction and using the processed signal portion for determining the direction of the repeater system signal transmission and for controlling the remote unit switch and the signal transmission direction; wherein the signal portion is derived from a radio-frequency (RF) control signal generated by the TDD repeater system and wherein the control unit drives the remote unit switch at a frequency determined from the processed signal portion. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
