METHOD AND SYSTEM FOR HANDLING RADIO SIGNALS IN A RADIO BASE STATION
First Claim
1. A base station for communication with at least one mobile terminal, said base station comprising:
- an antenna arrangement for receiving a signal from said at least one mobile terminal, said antenna arrangement being of either a first or a second type;
receive processing circuitry for performing a first set of signal processing tasks on said signal; and
a processor for performing a second set of signal processing tasks, said second set of signal processing tasks being selected by said processor based upon whether said antenna arrangement is of said first or said second type.

Abstract
A radiocommunication system is described wherein a flexible transceiver is provided that can be switchably connected to different antenna structures. Switching matrices are provided between the antenna elements and the receive processing circuitry which, under the control of the central processing unit, allows the transceiver to handle the different antenna structures. The enhanced flexibility achieved by the present invention provides a novel transceiver which can, for example, be reconfigured between and during calls to dynamically assign resources based upon changes in the amount and type of load being experienced by the system and adjusted in order to render existing operating functions more efficient.
