AI Technical Summary

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 present application discloses a terminal device, including: a first antenna, a second antenna, a first channel electrically connected to the first antenna, a second channel electrically connected to the second antenna; the first channel Including at least two first transmission branches, the at least two first transmission branches are used to transmit carrier signals for carrier aggregation through the first antenna; the second channel includes a signal that is electrically connected to the second antenna A receiving branch and a receiving filter electrically connected to the receiving branch, the receiving branch is used to receive the carrier aggregation signal through the second antenna, and the receiving filter is used to filter the carrier aggregation signal , to obtain the carrier signal for 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...
