1. A dual-mode communication terminal comprising:

  • a first communication module configured to communicate with a first base station that is a long term evolution (LTE) base station;

    a second communication module configured to communicate with a second base station;

    a first antenna connected to the first communication module in order to receive a first base station signal from the LTE base station; and

    a second antenna configured to receive either the first base station signal from the first base station or to receive a second base station signal from the second base station, the second antenna comprising a switching module configured to connect the second antenna to either the first communication module or the second communication module,wherein the first communication module is further configured to measure quality of the second base station signal received from the second base station in response to receiving a command from the LTE base station,wherein the quality of the second base station signal is measured while receiving the first base station signal from the LTE base station via the first and second antennas,wherein the switching module is further configured to switch the second antenna between the first communication module and the second communication module, andwherein the first communication module is further configured to;

    report a rank indicator (RI) as N to the LTE base station, andreport a precoding matrix index (PMI) based on a layer N while the first base station signal is received via the first and second antennas.
