Description

Radio frequency circuit, intelligent terminal, communication control method and storage medium

Technical Field

The present application relates to the field of radio frequency technologies, and in particular, to a radio frequency circuit, an intelligent terminal, a communication control method, and a storage medium.

Background

Due to the cost and maturity of the 5G core network, the 5G base station in the NSA mode preferentially accesses the 4G core network (EPC), so the Option 3 series (Option 3x) is the first choice for introducing the eMBB service in the 5G initial stage. The option 3 series architecture is a Dual Connection with 4G as the primary node and 5G as the secondary node, and is therefore also called EN-DC (EUTRA-NR Dual Connection). In such a dual connectivity architecture, the handset has two paths to the core network via the 4G or 5G base station.

In the course of conceiving and implementing the present application, the inventors found that at least the following problems existed: since the different power amplifier circuits in the two paths cannot share a power supply, they are split into two separate transmit paths. However, the receiving and main set transceiving common ends have to multiplex one port due to the port, and need to add a switch for realization, and the main set receiving part needs to use two multiplexing switches due to the insufficient port of the MLNA. The scheme needs four duplex switches and three multipath selection switches and matching circuits thereof, and seriously restricts the space of a swing part and the cost of a product.

The foregoing description is provided for general background information and is not admitted to be prior art.
