Abstract

The invention discloses an antenna multiplexing radio frequency device and a terminal. The antenna multiplexing radio frequency device comprises a plurality of antennas, a radio frequency circuit, a gating module for connecting the plurality of antennas and a plurality of radio frequency front-end modules, and a control module for connecting the radio frequency circuit and the gating module. The radio frequency circuit comprises a plurality of radio frequency front-end modules working in different frequency bands; the control module is used for controlling the gating module to be in gating connection with the at least one antenna and the currently working radio frequency front end module, so that the currently working radio frequency front end module works through the at least one antenna.According to the antenna multiplexing radio frequency device provided by the embodiment of the invention, a plurality of radio frequency front-end modules with different frequency bands can transmitsignals or receive signals through the same antenna, so that antenna multiplexing is realized to reduce the requirement of a multimode communication terminal on the number of antennas, and meanwhile,the cost and the design complexity of the terminal are reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an antenna multiplexing radio frequency device and a terminal. Background technique [0002] 5GNR is a global 5G standard based on a new air interface design based on Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal Frequency Division Multiplexing). In non-independent networking, 5G NR terminals need to support EN-DC mode, that is, E-UTRA-NR dual connectivity, and 5G NR terminals can connect to 5G base stations and LTE base stations at the same time. [0003] In related technologies, 5G communication requires 4*4 antennas, and 4G communication requires up to 4*4 antennas (compatible with 2G and 3G). When a 5G NR terminal works in EN-DC mode, it needs up to 4+4=8 antennas. However, so many antennas are a huge challenge for the limited space of 5G NR terminals. Contents of the invention [0004] The invention provides an antenna multiplexing radio frequency ...
