Abstract

Embodiments disclose a multi-frequency transceiver and a base station. The multi-frequency transceiver is connected to an antenna, and includes: at least one transmit multiplexer, where each transmit multiplexer includes multiple transmit paths, and each transmit path is used to transmit one frequency band by using the antenna; and at least one receive multiplexer, where each receive multiplexer includes multiple receive paths, and each receive path is used to receive one frequency band by using the antenna.

First claim

What is claimed is:

1 . A multi-frequency transceiver, comprising:
a first transmit multiplexer comprising a plurality of transmit paths, wherein each transmit path is used to transmit a signal in one frequency band using an antenna; and a first receive multiplexer comprising a plurality of receive paths, wherein each receive path is used to receive a signal in one frequency band by using the antenna.

2 . The multi-frequency transceiver according to claim 1 , wherein the plurality of transmit paths comprises a transmit path of each frequency band in N frequency bands, and the plurality of receive paths comprises a receive path of each frequency band in the N frequency bands, wherein N is a positive integer greater than or equal to 2.

3 . The multi-frequency transceiver according to claim 2 , further comprising:
a second transmit multiplier, wherein each transmit multiplexer comprises a transmit path of each frequency band in three frequency bands; and a second receive multiplexer, a third receive multiplexer, and a fourth receive multiplexer, wherein each receive multiplexer comprises a receive path of each frequency band in the three frequency bands.

4 . A multi-frequency transceiver, comprising a plurality of multiplexers, wherein each multiplexer comprises:
a single transmit path, used to transmit a signal in one frequency band by using an antenna; and a first receive path, wherein the first receive path is used to receive a signal in one frequency band by using the antenna.

5 . The multi-frequency transceiver according to claim 4 , wherein the frequency band transmitted by the single transmit path is the same as the frequency band received by the first receive path.

6 . The multi-frequency transceiver according to claim 5 , wherein each multiplexer further comprises a second receive path, and wherein the frequency band received by the first receive path is different from a frequency band received by the second receive path.

7 . The multi-frequency transceiver according to claim 4 , wherein the frequency band transmitted by the single transmit path is different from the frequency band received by the first receive path.

8 . The multi-frequency transceiver according to claim 7 , wherein each multiplexer further comprises a second receive path, and wherein the frequency band received by the first receive path is different from a frequency band received by the second receive path.

9 . The multi-frequency transceiver according to claim 4 , wherein the plurality of multiplexers comprises N multiplexers, and in each multiplexer of the N multiplexers, a frequency band transmitted by a transmit path is one of N frequency bands, a frequency band comprised in each receive path is one of the N frequency bands, and a frequency band transmitted by a transmit path in each multiplexer is different from a frequency band transmitted by a transmit path in any other multiplexer in the N multiplexers, wherein N is a positive integer greater than or equal to 2.

10 . The multi-frequency transceiver according to claim 9 , wherein the N multiplexers comprise M multiplexers, and each multiplexer in the M multiplexers comprises a same quantity of receive paths, wherein M is a positive integer less than N.

11 . The multi-frequency transceiver according to claim 9 , wherein the N multiplexers comprise a multiplexer in which a quantity of receive paths is different from a quantity of receive paths in another multiplexer of the N multiplexers.

12 . The multi-frequency transceiver according to claim 9 , wherein in the N multiplexers a total quantity of receive paths that receive a frequency band in the N frequency bands is the same as a total quantity of receive paths that receive another frequency band in the N frequency bands.

13 . The multi-frequency transceiver according to claim 9 , wherein the N frequency bands comprise a frequency band in which a total quantity of receive paths that receive the frequency band in the N multiplexers is different from a total quantity of receive paths that receive another frequency band in the N frequency bands in the N multiplexers.

14 . A base station, comprising a multi-frequency transceiver, wherein the multi-frequency transceiver comprises:
a first transmit multiplexer comprising multiple transmit paths, wherein each transmit path transmits a signal in one frequency band by using an antenna; and a receive multiplexer, wherein each receive multiplexer comprises a plurality of receive paths, and each receive path is used to receive a signal in one frequency band using the antenna.

15 . The base station according to claim 14 , wherein the first transmit multiplexer comprises a transmit path of each frequency band in N frequency bands, and the receive multiplexer comprises a receive path of each frequency band in the N frequency bands, wherein N is a positive integer greater than or equal to 2.

16 . The multi-frequency transceiver according to claim 15 , wherein multi-frequency transceiver further comprises a second transmit multiplexer, and each transmit multiplexer comprises a transmit path of each frequency band in three frequency bands; and wherein the multi-frequency transceiver further comprises a second receive multiplexer, a third receive multiplexer, and a fourth receive multiplexer, and each receive multiplexer comprises a receive path of each frequency band in the three frequency bands.
