Abstract

A multi-band multi-path receiving and transmitting device and method, and a base station system are provided. The multi-band multi-path receiving and transmitting device includes a broadband antenna, at least two multi-frequency couplers, a multi-band transceiver, and a signal processing module. The multi-band transceiver is adopted to decrease the number of the transceivers, thereby reducing the material cost and the mounting cost of the base station system.

Claims

1. A multi-band transceiver, comprising:

at least two first frequency band receiving branches, at least two second frequency band receiving branches, and a first frequency band transmitting branch,

wherein the at least two first frequency band receiving branches are configured to receive first frequency band signals from a first multi-frequency coupler and a second multi-frequency coupler, and to send the first frequency band signals to a baseband processing module;

wherein the at least two second frequency band receiving branches are configured to receive second frequency band signals from the first multi-frequency coupler and the second multi-frequency coupler, and to send the second frequency band signals to the baseband processing module;

wherein the first frequency band transmitting branch is configured to receive another first frequency band signal from the baseband processing module, and to send the another first frequency band signal to the first multi-frequency coupler.

2. The multi-band transceiver according to claim 1, further comprising:

a second frequency band transmitting branch, configured to receive another second frequency band signal from the baseband processing module, and configured to send the another second frequency band signal to the second multi-frequency coupler.

3. The multi-band transceiver according to claim 2, wherein the at least two first frequency band receiving branches, the at least two second frequency band receiving branches, the first frequency band transmitting branch, and the second frequency band transmitting branch are integrated in the multi-band transceiver.

4. The multi-band transceiver according to claim 1, wherein the at least two first frequency band receiving branches, the at least two second frequency band receiving branches, and the first frequency band transmitting branch are integrated in the multi-band transceiver.

5. The multi-band transceiver according to claim 1, further comprising:

a first frequency band transceiver and a second frequency band transceiver,

wherein the at least two first frequency band receiving branches and the first frequency band transmitting branch are integrated in the first frequency band transceiver;

wherein the at least two first frequency band receiving branches are integrated in the second frequency band transceiver.

6. The multi-band transceiver according to claim 1, wherein the first multi-frequency coupler and the second multi-frequency coupler are located inside the multi-band transceiver.

7. The multi-band transceiver according to claim 1, wherein the first frequency band or the second frequency band is a frequency band from 1710 MHz to 2690 MHz.
