Claim:
1. A transmission apparatus for receiving a plurality of uplink (UL) signals from a user equipment (UE) and transmitting the plurality of received UL signals to a base station (BS) in a wireless communication system, the transmission apparatus comprising: a plurality of reception antennas (Nrx,REP Rx antennas) configured to receive a plurality of UL signals from the UE; a radio frequency (RF) repeater configured to amplify and map the plurality of received UL signals to at least one transmission antenna; and a plurality of transmission antennas (Ntx,REP Tx antennas) configured to transmit the plurality of amplified UL signals to the BS, wherein the RF repeater is further configured to select M received UL signals from among Nrx,REP received UL signals which are received by the Nrx,REP Rx antennas, and map the M received UL signals to N Tx antennas from among the Ntx,REP Tx antennas, wherein if M is higher than N, the RF repeater is configured to perform grouping of the M received UL signals to N signal groups, where one of the N signal groups is respectively mapped to one of the N Tx antennas, wherein the N signal groups comprise a first signal group which includes relatively good-quality UL signals among the M received UL signals and a second signal group which includes relatively poor-quality UL signals among the M received UL signals, and wherein a number of UL signals belonging to the first signal group is less than a number of UL signals belonging to the second signal group.
