1. A frequency division duplex (FDD) wireless communication apparatus comprising:
- a first antenna configured to one of transmit or receive;
a second antenna configured to receive;
a switch configured to selectively connect one of the first antenna or the second antenna to a receiver; and
at least one processor configured to;
control switching of the switch based on a received signal power level,control to transmit and receive a signal via the first antenna, if the received signal power level is greater than or equal to a threshold value, andcontrol to transmit a signal via the first antenna and receive a signal via the second antenna, if the received signal power level is less than the threshold value.

9. A frequency division duplex (FDD) wireless communication apparatus comprising:
-
multiple transmitters and receivers corresponding to multiple different communication bands; a first antenna configured to one of transmit and receive; a second antenna configured to receive; a first switch configured to selectively connect the first antenna to a transmitter corresponding to a communication band used out of the multiple communication bands; a second switch configured to selectively connect one of the first antenna and the second antenna to a receiver corresponding to the used communication band through the first switch; and at least one processor configured to; control switching of the second switch based on a received signal power level, control to transmit and receive a signal via the first antenna, if the received signal power level is greater than or equal to a threshold value, and control to transmit a signal via the first antenna and receive a signal via the second antenna, if the received signal power level is less than the threshold value. - View Dependent Claims (10, 11)
