A NODE AND A METHOD FOR USE IN A WIRELESS COMMUNICATIONS SYSTEM

摘要

The invention relates to a relay or repeater node (21) for use in a wireless communications system said node comprising a receive antenna (23) for receiving a signal through a wireless connection, an amplifier (30) for amplifying the signal and a transmit antenna (27) for forwarding the amplified signal, said node further com- prising a mode switching unit (31) for switching between at least a first and a second mode of operation of the node in dependence of an amplification gain requirement. This enables optimization of the node for varying conditions in the network.
