First Claim
Patent Images
1. A node for use in a wireless communications system, said node comprising:
- a receive antenna side having at least one receive antenna for receiving a signal through a wireless connection;
an amplifier for amplifying the signal and a transmit antenna side having at least one transmit antenna for forwarding the amplified signal; and
a mode switching unit for switching between at least a first forwarding mode and a second forwarding mode of operation of the node in dependence of an amplification gain requirement, wherein said forwarding mode determines a way of utilizing resources by the transmit antenna side and the receive antenna side.

Abstract
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 comprising 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.
