Problems solved by technology

[0004] However, when traditional quadruplexers or hexaplexers are used to implement carrier aggregation, the insertion loss of the RF front-end is often large, which reduces the conduction performance of radio frequency reception, and the cost of implementing carrier aggregation is high

Abstract

The application discloses terminal equipment. The terminal equipment comprises a first antenna, a second antenna, a first channel electrically connected with the first antenna, and a second channel electrically connected with the second antenna; the first channel comprises at least two first transmitting branches, at least two first transmitting branches are used for sending a carrier signal for realizing carrier aggregation through the first antenna; the second channel comprises a receiving branch electrically connected with the second antenna and a receiving filter electrically connected with the receiving branch, wherein the receiving branch is used for receiving a carrier aggregation signal through the second antenna, and the receiving filter is used for filtering the carrier aggregation signal, thereby obtaining the carrier signal for realizing the carrier aggregation.

Description

technical field [0001] The present application relates to the communication field, and in particular to a terminal device. Background technique [0002] Carrier aggregation is a key technology in LTE-A. In order to meet the requirements of single-user peak rate and system capacity improvement, one of the most direct methods is to increase the system transmission bandwidth. Therefore, the LTE-Advanced system introduces a technology for increasing transmission bandwidth, that is, carrier aggregation (Carrier Aggregation, CA). The CA technology can aggregate 2 to 5 LTE component carriers (Component Carriers, CCs) together to achieve a maximum transmission bandwidth of 100 MHz, effectively improving the uplink and downlink transmission rates. The terminal device can use up to several carriers for uplink and downlink transmission at the same time according to its capability. [0003] Currently, a quadplexer or a hexaplexer is usually used to implement carrier aggregation. A q...
