INCREASED DIVERSITY BY MEANS OF REPEATERS
First Claim
1. A repeater for use in a wireless communications system, comprising receiving means for receiving a communication signal through the air interface from a communication unit in the communications system, signal processing means for processing the communication signal to produce an output signal, and transmitting means for transmitting the output signal, where said repeater comprises means for creating diversity in the output signal.

Abstract
The invention relates to communication in a wireless communications network in which a cell comprises areas with different topographies, for example between indoor and outdoor areas. The communication is optimized by means of a repeater for use in a fixed wireless broadband communications system, comprising receiving means for receiving a downlink signal from a base station, signal processing means for processing the downlink signal to produce an output signal, and transmitting means for transmitting the output signal, said repeater being characterized in that it comprises means for creating diversity in the output signal.

10. A communication method for use in a wireless communication system, for repeating signals transmitted by a communication unit in a wireless network, comprising the steps of
receiving in a repeater a communication signal from the communication unit, processing the communication signal to produce an output signal from the repeater, transmitting the output signal from the repeater in such a way as to create diversity.
-
18. A wireless communications system comprising at least one base station and at least one user terminal arranged to transmit communication signals to each other, said system further comprising a repeater, arranged to receive said communication signals from the base station and/or the user terminal, process the signals so as to create diversity and transmit the processed signals to the user terminal and/or the base station.

20. A communication method for use in a wireless communications system, comprising the steps of
transmitting from a first communication unit in the system a communication signal intended for a second communication unit in the system, receiving the communication signal in a repeater processing the communication signal to produce an output signal from the repeater transmitting the output signal from the repeater in such a way as to create diversity.
