Technical Field

The present invention relates to the field of communications, and in particular, to a radio frequency architecture and a terminal device.

Background

In a non-independent Networking (NSA) scheme, because both the MHB PAMID (Middle and high Band PA Module integrated multiplexer, Middle and high frequency Power Amplifier Module integrated multiplexer) and the N41 Module support New wireless (New Radio, NR) performance, a higher voltage is required for Power supply, and a Direct Current (dc) Power supply can be selected to be respectively externally hung for Power supply; the LB PAMID (Low Band PA Module) only supports LTE performance, and thus may be powered by a Power Management Integrated Circuit (PMIC). However, since the MHB PAMID and N41 modules require higher voltage power, i.e., higher performance requirements, the complexity of the radio frequency architecture increases.

Detailed Description

The embodiment of the invention provides a radio frequency framework and terminal equipment, which are used for reasonably optimizing the framework of a 4G and 5G dual-connection technical scheme, reducing the cost of PA components and achieving the purpose of reducing the cost of the whole machine.

In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. The embodiments based on the present invention should fall into the protection scope of the present invention.

The NSA scheme involved in the embodiments of the present invention can be briefly described as follows:

under an Enhanced Mobile Broadband (eMB) application scenario of 5G, an unprecedented requirement for data communication capability of a personal terminal device is provided by a geometrically-increased mass data demand, and both a 5G NSA (non-stand alone networking) and an SA (stand alone networking) deployment scheme are related to key scheme support in the aspect of improving communication rate, for example, 1T4R (1-way transmission and 4-way reception) under NSA, 2T4R (2-way transmission and 4-way reception) and 1T4R under SA are both used for improving communication rate, especially downlink communication rate; because of personal big data applications, such as short video, video movies, etc., the demand for downstream rates is higher.

Since the coverage area of the current 5G base station is small, the area of the current 5G base station is the same as that of Long Term Evolution (LTE), the number of the required 5G base stations is more than 3 times that of the former, and the network construction cost is increased suddenly. Due to the global economic development unevenness and different 4G to 5G evolution strategies in different countries, the global endec (E-UTRA NR Dual Connectivity, 4G and 5G Dual Connectivity) scheme will become an important 5G coverage scheme for a long time, i.e. the scheme using 4G and 5G Dual Connectivity ensures signal continuity in the area where the 5G signal is unstable or uncovered. ENDC is a dual connection of 4G and 5G, at present, in the global range, LTE has a plurality of frequency bands such as LB (Low Band, Low frequency)/MB (Middle Band, intermediate frequency)/HB (High Band), and the like, and 5G also has a plurality of frequency bands such as LB/MB/HB/SUB6G, so that any combination of the two can generate a plurality of ENDC schemes, such as common LB + LB, LB + MB, LB + HB, MB + HB, LB + SUB6G, MB + SUB6G and HB + SUB 6G. At present, the domestic requirements are MB + HB (B1/3/39+ N41), LB + SUB6G, MB + SUB6G and HB + SUB 6G.

A typical Radio Frequency (RF) architecture is currently shown in fig. 1: wherein, the NR/LTE MHB PAMID (Middle and high Band PA Module integrated multiplexer, Middle and high Band Power Amplifier Module) supports LTE and New Radio (NR) of MB and HB, and the LB PAMID (LB PA Module integrated multiplexer) supports LTE characteristics; because the NR/LTE MHB PAMID cannot support simultaneous transmission of MB and HB, in order to support the M + H ENDC requirement, a single N41 PA module is required to be hung externally.

However, the two DCDCs bring about a significant cost increase, and the cost of N41 PAM (Power Amplifier Module, PA Module, Power Amplifier Module) itself is also high.

The following describes terms used in the following examples of the present invention, as follows:

a dc power supply, Direct Current Source, dc converter, means a device that converts a dc power supply of a certain voltage class into a dc power supply of another voltage class. The DC/DC is divided into a boost power supply and a buck power supply according to the voltage grade conversion relation, and is divided into an isolated power supply and a non-isolated power supply according to the input and output relation. For example: the DC/DC converter connected to the on-vehicle DC power supply converts high-voltage DC power into low-voltage DC power.

The Power Management integrated circuit is used for managing Power supply equipment in a host system and is commonly used for mobile phones and various mobile terminal equipment.

High Band (HB), medium Band (Mid Band, MB), Low Band (LB), and N41 is a 5G Band. Wherein, the frequency range of N41 is 2496MHz-2690MHz, the frequency range of HB is 2300MHz-2690MHz, the frequency range of MB is 1710MHz-1980MHz, and the frequency range of LB is 663MHz-915 MHz. SUB6G refers to 5G frequency band, and the working frequency is below 6G frequency band of 450MHz-6000 MHz.

A Power Amplifier (PA), referred to as "power amplifier" for short, refers to an amplifier that can generate maximum power output to drive a certain load under a given distortion rate. The power of the power supply is converted into a current varying according to an input signal by using a current control function of a transistor or a voltage control function of a field effect transistor. For example, the speakers, power amplifiers play the role of "organisation and coordination" in the overall sound system, in part, governing whether the overall system can provide good sound quality output. The PA is a great help in the era of wide application in the field of the current Internet of things.

Among these, a power amplifier generally includes 3 parts: preamplifier, drive amplifier, final stage power amplifier. The preamplifier has matching function, the input impedance is high (not less than 10k omega), the former signal can be absorbed mostly, the output impedance is low (less than tens of omega), and the signal can be transmitted mostly. Meanwhile, the amplifier is a current amplifier, converts an input voltage signal into a current signal and provides proper amplification. The driving amplifier plays a role of a bridge, and further amplifies the current signal sent by the preamplifier to amplify the current signal into a signal with medium power to drive the final power amplifier to normally work. Without a driver amplifier, the final power amplifier cannot deliver a powerful sound signal. The final power amplifier plays a key role. It will drive the current signal that the amplifier sent to form the high-power signal.

In the embodiment of the present invention, the second power supply 201 and the third power supply 301 are the same integrated power management circuit PMIC power supply, because the second PA module supports the low frequency band LB in LTE, and the third PA module supports the middle frequency band MB in LTE, the requirements of the second PA module and the third PA module on voltage are not very high, and the PMIC power supply can be used to supply power to the second PA module and the third PA module.

Optionally, the first power supply is a dc-to-dc power supply DCDC power supply. Fig. 3G is a schematic diagram of another embodiment of the terminal device provided in the embodiment of the present invention. In the embodiment of the invention, the first PA module supports the N41 frequency band and the MHB of the middle and high frequency band in the new wireless NR/LTE, so the requirement on the voltage is higher, and in order to meet the working requirement, the DCDC power supply is used for supplying power to the first PA module. The DCDC power supply can flexibly adjust the voltage boosting and the voltage reducing, can provide a larger voltage range, and can better meet the requirements of users.

Optionally, the first PA module 102, the second PA module 202, and the third PA module 302 are modules integrated by a plurality of power amplifiers, respectively. In the embodiment of the invention, the first PA module can also be called NR/LTE MHB PAMID, the second PA module can also be called LTE LB PAMID, and the third PA module can also be called LTE MB PAMID. Namely, the external small PA module only supporting LTE MB is hung, HB NR under M + H ENDC goes through an NR/LTE MHB PAMID channel, and the LTE MB goes through an LTE MB PAMID channel; since the LTE LB PAMID and the LTE MB PAMID do not operate simultaneously and both operate in the LTE mode, one PMIC may be used to supply power to both simultaneously. Therefore, one DCDC power supply is saved, and meanwhile, the cost of the LTE MB PAMID scheme is far lower than that of the N41 PAM; by reasonably optimizing the ENDC scheme architecture, the use quantity of DCDCDC is reduced to the maximum extent, meanwhile, the cost of PA components is reduced, and the purpose of reducing the cost of the whole machine is achieved.
