Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0042] Embodiment 1 of the present invention discloses a carrier aggregation circuit. The carrier aggregation circuit is used for signal transmission through three frequency bands. Specifically, the three frequency bands include: the transmission frequency band and the receiving frequency band of the main carrier, and the receiving frequency band of the auxiliary carrier. band.

[0043] During the carrier aggregation process, the carrier aggregation circuit is...

Abstract

The invention provides a carrier aggregation circuit. The carrier aggregation circuit is used for transmitting signals through three frequency bands, which comprise a transmitting frequency band and a receiving frequency band of a main carrier and a receiving frequency band of an auxiliary carrier; the carrier aggregation circuit comprises: a first antenna; at least one first device connected with the first antenna; a second antenna; at least one second device connected with the second antenna; one antenna in the first antenna and the second antenna is used for transmitting signals of two frequency bands through the same device connected with it, and the other antenna is used for transmitting the signal of one frequency band by another device connected with it; different devices are arranged on different links and the frequency ranges are different; and the device for transmitting the signals of two frequency bands is a duplexer. According to the carrier aggregation circuit provided by the invention, signal transmitting and receiving are separated by the duplexer to reduce the insertion dissipation, the signal transmitting and receiving are achieved by two antennas to solve the problem of a poor isolation degree between different frequency bands, thereby improving the data transmission efficiency of the carrier aggregation circuit.

Description

technical field [0001] The present invention relates to the field of self-communication, and more specifically relates to a carrier aggregation circuit. Background technique [0002] Carrier aggregation technology is a technology that combines different frequency bands for common transmission to form a sufficiently large equivalent bandwidth to provide high-speed wireless network services. At present, various operators around the world combine the frequency bandwidths of different frequency bands such as two-two or three-three through the frequency band bandwidth allocated by themselves to achieve the maximum bandwidth of communication work transmission bandwidth to achieve faster data transmission rate. [0003] The carrier aggregation can be divided into two types: intra-band carrier aggregation and inter-band carrier aggregation. For intra-band carrier aggregation, since different carrier paths carried by it are still the same, it has little impact on the architecture of...
