Abstract
A Frequency Division Duplex (FDD) wireless communication apparatus is provided. The FDD wireless communication apparatus includes a first antenna configured to one of transmit and receive, a second antenna configured to receive, and a switch configured to selectively connect one of the first antenna and the second antenna to a receiver.
Claims17
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, 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.

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.
7 more elements
A frequency division duplex (FDD) wireless communication method comprising:
- connecting one of a first antenna for one of transmitting or receiving and a second antenna for receiving to a receiver;
- transmitting and receiving a signal via the first antenna, if the received signal power level is greater than or equal to a threshold value;
- and
- transmitting a signal via the first antenna and receiving a signal via the second antenna, if the received signal power level is less than the threshold value.
