Abstract:
1. A user equipment (UE), comprising: a first antenna configured to both receive and transmit a first signal corresponding to a first frequency band, a second signal corresponding to a second frequency band and a third signal corresponding to a third frequency band; a second antenna configured to receive the first signal, the second signal and the third signal; a first wireless communication chip comprising a first Tx port for transmitting both the first and the second signal, a first primary Rx port for receiving the first signal and the second signal, and a first diversity Rx port for receiving the second signal; a second wireless communication chip comprising a second Tx port for transmitting the third signal, a second Primary Rx port for receiving the third signal and a second diversity Rx port for receiving the third signal; and a radio frequency (RF) front-end module configured to: transmit the first and second signals output from the first wireless communication chip to the first antenna, transmit the third signal output from the second wireless communication chip to the first antenna, transmit the first and second signal externally received in the first antenna to the first wireless communication chip, transmit the first and second signal externally received in the second antenna to the first wireless communication chip, and transmit the third signal received in the first and second antennas to the second wireless communication chip, wherein all the signals received via the first antenna other than the second signal are transmitted to the primary Rx ports of the first and second communication chips whereas the second signal received via the first antenna is transmitted to the diversity Rx port of the first communication chip, wherein all the signals received via the second antenna other than the second signal are transmitted to the diversity Rx ports of the first and second communication chips whereas the second signal received via the second antenna is transmitted to the primary RX port of the first communication chip, and wherein the first wireless communication chip is configured to use a first wireless communication scheme, and the second wireless communication chip is configured to use a second wireless communication scheme that is different than the first wireless communication scheme.
