Abstract

Embodiments of the invention provide a radio frequency transmit-receive apparatus, a terminal and a method. The radio frequency transmit-receive apparatus comprises a first antenna unit, a duplexer, a radio-frequency unit and a signal selection unit. The radio frequency transmit-receive apparatus, the terminal and the method can solve a problem of inflexible uplink and downlink resource allocation in a radio frequency transmit-receive apparatus in the prior art.

Description

technical field [0001] Embodiments of the present invention relate to wireless communication technologies, and in particular to a radio frequency transceiver device, terminal and method. Background technique [0002] In the long-term evolution of communication technology (LTE for short), according to the duplex mode, it can be divided into Frequency Division Duplexing (FDD for short) and Time Division Duplexing (TDD for short). ) of two types. In the FDD working mode, the uplink and downlink channels use different frequency points, and both uplink and downlink transmissions use frames with a fixed time length. In the TDD working mode, the uplink and downlink are transmitted in different time slots, and they usually share the same frequency. Compared with FDD, TDD has the characteristics of high frequency utilization and flexible allocation of uplink and downlink resources. [0003] A carrier aggregation (Carrier Aggregation, CA for short) technology is a key technology in...
