Background

Currently, 5G (5 th Generation Mobile Communication Technology, fifth generation mobile communication technology) networks are limited in uplink to terminals, frame structures and frequency bands, and experience is far from being downlink.

In order to enhance the Uplink transmission capability, the communication interface proposes a super Uplink technology (Uplink switching), and Uplink coverage and rate effects are enhanced by using an Uplink selective transmission function of a terminal. For example, in an area outside of the uplink coverage of the NR (New Radio) TDD (Time Division Duplexing, time division duplex), the terminal transmits data by using FDD (Frequency Division Duplexing, frequency division duplex) and TDD, respectively, 1TX (transmission Channel). In the UpLink coverage area shared by FDD and TDD, the UpLink time slot of TDD is switched to a mode that the TDD carrier uses 2Tx, that is, UL (UpLink) MIMO (multiple-in multiple-out) to transmit data, so as to improve the UpLink throughput rate.

When the 5G uplink transmission is promoted in the mode, in order to consider the throughput and the uplink coverage, only 1TX of FDD and TDD can be adopted to send uplink data when the terminal is in the middle zone covered by TDD and FDD, so that the promotion of the uplink performance in the middle zone covered by TDD and FDD is limited.

Detailed Description

Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Some concepts and/or terms involved in the schemes provided in the embodiments of the present application are explained below.

Frequency Division Duplexing (FDD), also known as full duplexing, refers to operation of the uplink (mobile to base station) and downlink (base to mobile) with two separate frequencies (with a certain frequency spacing requirement), i.e., two separate channels are required for operation. One channel is used to transmit information downward and the other channel is used to transmit information upward. A guard band exists between the two channels to prevent mutual interference between adjacent transmitters and receivers.

In a mobile communication system in a TDD mode, in which a transmitter and a receiver do not operate simultaneously, interference cannot be generated between them, and thus reception and transmission are performed in different time slots of the same frequency channel (i.e., carrier), the reception and transmission channels are separated by a guaranteed time.

Currently, two uplink enhancement technologies SUL (supplementary uplink) and UL CA (carrier aggregation ) are proposed by 3GPP (3 rd Generation Partnership Project, third generation partnership project), essentially by TDD/FDD, high frequency/low frequency co-complementary pair uplink enhancement. Referring to fig. 1, the sul can only perform uplink transmission on one carrier at the same time, and is mainly used for improving the coverage rate of the cell edge, but cannot improve the capacity of the near point; UL CA uplink two carriers are concurrent, and there is limited uplink capacity boost at near points.

The above conventional SUL and UL CA technologies have certain disadvantages, and in recent years, the communication industry proposes a super Uplink technology (Uplink switching), and further enhances Uplink coverage and rate effects (for example, uplink data is sent through an FDD carrier in a downlink slot of TDD and Uplink data is sent through a TDD carrier in an Uplink slot of TDD), and a signal transmission mode refers to fig. 2, which shows a slot diagram of TDD2TX and FDD1TX time division transmission, where U represents Uplink, D represents downlink, and S represents a special frame isolating U and D.

Taking UL CA fdd+tdd as an example, the UE (terminal) is located at a far point of the cell, and preferentially sends uplink data through an FDD (low frequency) carrier, so as to ensure that the network has a larger coverage area; the UE is located at a cell near point, the uplink time slot of the TDD switches the UE to the NR TDD carrier for uplink scheduling, at the moment, the UE can use UL MIMO for data transmission on the NR carrier, and the NR has larger bandwidth and higher frequency spectrum efficiency compared with the LTE (Long Term Evolution ), so that the uplink transmission rate can be improved, and the LTE FDD can be used for uplink data transmission on the downlink time slot and the special time slot of the NR TDD carrier; however, when the UE is in the middle point, that is, the middle zone between the far point and the near point, the throughput and the uplink coverage need to be considered, and the current UE is a 2TX terminal, and only FDD 1tx+tdd 1TX can be adopted to send uplink transmission.

Referring to fig. 3, an embodiment of the present application discloses a signal emission control method applied to an electronic device, where the electronic device supports carrier aggregation, the electronic device includes a plurality of power amplifiers, the power amplifiers are powered by three power sources, and the number of power amplifiers connected by each power source is greater than or equal to one, and the method includes:

step 101, obtaining an uplink signal strength value of a terminal.

In this embodiment, referring to fig. 4, the rfic is denoted as a radio frequency transceiver, the LBPA, the MHB PA, the NR MMPA, the N78 PA0, and the N78 PA1 are denoted as a plurality of power amplifiers for different transmit power levels, the APT/ET is denoted as a power supply, the plurality of power amplifiers are powered by three power supplies, and the number of power amplifiers connected to each power supply is greater than or equal to one. The radio frequency transceiver is configured to output LTE signals and/or NR signals, and perform signal processing on LTE signals and/or NR signals received by one or more antennas, where the signal processing includes, but is not limited to, frequency conversion, demodulation, analog-to-digital conversion, and the like. The uplink signal transmitted by the radio frequency transceiver is amplified by the power amplifier and then transmitted by the antenna. The antenna is a transducer for converting radio frequency signals into electromagnetic waves of a corresponding wavelength and radiating them into the air and/or for receiving electromagnetic waves and converting them into corresponding radio frequency signals. It will be appreciated that the same antenna may transmit radio frequency signals as well as receive radio frequency signals. The radio frequency signals may include LTE signals, NR signals, and the like. The input end of the power amplifier is connected with the radio frequency transceiver, the output end of the power amplifier is connected with the antenna, the power amplifier is also connected with the power supply, and when the terminal transmits an uplink signal in a preset frequency band, the power supply supplies power to the power amplifier connected with the preset frequency band, so that the transmission of the uplink signal is realized. The distance between the terminal and the base station can be judged by acquiring the uplink signal strength value of the terminal, so as to determine how the current terminal performs uplink transmission.

Optionally, step 101 specifically includes:

sub-step 1011, obtaining a first signal and a second signal, where the first signal is used to characterize a signal value transmitted by the base station received by the terminal, and the second signal is used to characterize a signal value transmitted to the base station after the terminal receives the first signal.

Sub-step 1012, determining an uplink signal strength value of the terminal according to the difference between the first signal and the second signal.

In this embodiment of the present application, the first signal may be an SRS (Signal Receiving Power channel sounding reference signal), the second signal may be an RSRP (Reference Signal Receiving Power, reference signal received power)), and by measuring the SRS and the RSRP, whether there is coverage in the TDD uplink is detected. In wireless communication, SRS is used for estimating up channel frequency domain information and carrying out frequency selective scheduling; the RSRP is used for estimating a downlink channel and performing downlink beam shaping. That is, the uplink signal strength value of the terminal can be determined by the difference between the signal value of the SRS signal transmitted to the terminal by the base station and the signal value of the RSRP transmitted to the base station after the terminal receives the SRS signal value. And determining how the current terminal transmits the uplink signal according to the uplink signal strength value.

Step 102, if the uplink signal strength value is greater than the first threshold and less than the second threshold, determining that the terminal is at the midpoint of the cell, and controlling three power supplies to respectively supply power to the connected power amplifiers simultaneously, so as to realize simultaneous uplink transmission of three transmission channels.

In this embodiment, referring to fig. 5, fig. 5 is a signal coverage diagram, where R1 is denoted as coverage of TDD signals, R2 is denoted as coverage of FDD signals, when a terminal is located within R1, it indicates that the terminal is located at a near point of a base station, when the terminal is located outside R1, it indicates that the terminal is located at a far point of the base station, and when the terminal is located within r1±δ, it indicates that the terminal is located in an intermediate zone between TDD and FDD coverage. The first threshold may be a signal strength value when the terminal is at the position of r1+δ and the second threshold may be a signal strength value when the terminal is at the position of r1- δ. When the uplink signal intensity value of the terminal is judged to be larger than the first threshold value and smaller than the second threshold value through obtaining the uplink signal intensity value of the terminal, the terminal is determined to be in the middle zone, at this time, in order to improve the uplink signal transmitting power of the middle zone, the TDD2TX transmission can be activated, so that three power supplies work simultaneously, three transmission channels work simultaneously, namely FDD1TX+TDD 2TX is realized to send uplink transmission simultaneously, and the uplink transmitting power of the terminal is improved when the terminal is in the middle zone.

After the TDD2TX transmission is activated, it is determined whether there is a harmonic or intermodulation interference signal in the uplink signal to determine whether NR and LTE are transmitted simultaneously.

The first power amplifier LBPA is used for amplifying a low-frequency signal transmitted by the low-frequency port LB TX, the second power amplifier MHB PA is used for amplifying an intermediate-frequency signal or a high-frequency signal transmitted by the first intermediate-frequency port MB TX1 and the first high-frequency port HB TX1, the third power amplifier NR MMPA is used for amplifying an intermediate-frequency signal and a high-frequency signal transmitted by the second intermediate-frequency port MB TX2 and the second high-frequency port HB TX2, the fourth power amplifier N78 PA0 is used for amplifying a first ultrahigh-frequency signal transmitted by the first ultrahigh-frequency port UHB TX1, the fifth power amplifier N78 PA1 is used for amplifying a second ultrahigh-frequency signal transmitted by the second ultrahigh-frequency port UHB TX2, wherein the low-frequency port of the radio-frequency transceiver may be a port integrating a plurality of low-frequency sub-bands, the intermediate-frequency port may be a port integrating a plurality of high-frequency sub-bands, and the ultrahigh-frequency port may be a port integrating a plurality of ultrahigh-frequency sub-bands. When the terminal transmits signals, the uplink signals are transmitted by the corresponding ports according to the frequency band supported by the terminal, amplified by the power amplifier corresponding to the frequency band, and transmitted by the antenna.

Referring to fig. 4, if harmonic or intermodulation interference signals exist, a third target port is determined from the low frequency port LB TX, the first intermediate frequency port MB TX1, the second intermediate frequency port MB TX2, the first high frequency port HB TX1, the second high frequency port HB TX2 for FDD1TX transmission, and the first ultra-high frequency port UNB TX1 and the second ultra-high frequency port UHNTX2 for TDD 2TX transmission. Reference is made to the transmission slots shown in fig. 2 in a manner of FDD1TX and TDD 2TX time division transmissions, TDD TX and FDD TX bursts. By time division transmission, mutual interference between signals is avoided.

And step 1023, if no harmonic or intermodulation interference signal exists, determining a fourth target port from the low-frequency port, the first intermediate-frequency port and the first high-frequency port, performing uplink transmission on the fourth target port, the first ultrahigh-frequency port and the second ultrahigh-frequency port at the same time, and controlling a power supply to supply power to power amplifiers corresponding to the fourth target port, the first ultrahigh-frequency port and the second ultrahigh-frequency port at the same time.

In this embodiment of the present application, referring to fig. 4, if no harmonic or intermodulation interference signal exists, FDD1TX and TDD 2TX are used for simultaneous transmission, that is, 3TX is used for simultaneous transmission of uplink transmission, a fourth target port may be determined from the low frequency port LB TX, the first intermediate frequency port MB TX1, and the first high frequency port HB TX1, where the fourth target port is used for implementing FDD1TX transmission, and the first ultrahigh frequency port UHBTX1 and the second ultrahigh frequency port UHB TX2 are used for implementing TDD 2TX transmission, which not only can ensure uplink coverage stability, but also can meet uplink rate requirements (especially, in the middle zone position, without backing to FDD1TX and TDD 1TX transmission), and referring to the signal time slot diagram of fig. 6, the thickened U in the diagram represents a time slot of uplink transmission.

Optionally, the three power supplies are respectively: the power amplifier comprises a first power supply, a second power supply and a third power supply, wherein the first power supply is connected with a first power amplifier and a second power amplifier, the second power supply is connected with the third power amplifier and a fourth power amplifier, the third power supply is connected with a fifth power amplifier, and the substep 1023 specifically comprises:

substep 10231, controlling the first power supply to supply power to the first power amplifier or the second power amplifier, the second power supply to supply power to the fourth power amplifier, and the third power supply to supply power to the fifth power amplifier.

So that different power supplies can be scheduled to supply power to the power amplifier according to different positions of the terminal, the signal transmission of the terminal under different uplink transmission scenes is realized,

Further, the first power supply, the second power supply, and the third power supply may be an average power tracking mode (APT) power supply, or an envelope tracking mode (ET) power supply. When the power supply is in an average power tracking mode, the power supply is connected with the radio frequency transceiver, and the radio frequency transceiver controls the power supply to supply power; when the power supply is in the envelope tracking mode, the power supply is connected with the integrated power supply management circuit, and the integrated power supply management circuit controls the power supply to supply power. An Envelope Tracking (ET) mode power supply is a technology for establishing a connection between an operating voltage of a power amplifier and an input radio frequency signal to enable the operating voltage and the input radio frequency signal to follow each other in real time, so that the operating efficiency of the power amplifier is improved. An Average Power Tracking (APT) mode power supply is a technique for automatically adjusting the operating voltage of a power amplifier according to the pre-output power of the power amplifier in combination with its own parameters.

Referring to fig. 4, by setting three power supplies and judging the position of the terminal, the uplink throughput of the middle zone position area is maximally improved, thereby improving the user experience and the time delay; aiming at different application scenes, the uplink transmission mode is flexible and changeable; the SOC chip module of the circuit multiplexing platform chip basically has no newly added hardware cost, like the BUCK module of figures 7 and 8, most of the projects are not used at present, the circuit multiplexing platform chip SOC chip module does not need to be purchased separately, can be used together with a power switch, and reduces the cost.

At this time, compared with the power supply by adopting three ET power supplies, the power supply reduces one ET power supply, reduces occupation of layout space of a PCB (Printed Circuit Board, a printed circuit board), realizes power supply change of a power amplifier under different uplink transmission scenes by a change-over switch, and basically does not cause pressure on cost and PCB layout while increasing performance.

Further, taking CA_n1-n78 as an example, the n1 band is amplified by MHB PA. When the terminal is at a far point of a cell, as n78 has large propagation loss and weak uplink coverage capacity, uplink transmission is carried out only through n1 1TX, and at the moment, APT/ET0 supplies power to MHB PA (the performance of the APT/ET0 is better than that of BUCK APT, so that power is preferentially supplied through the APT/ET 0); when the terminal is in a middle zone of a cell, and uplink coverage capacity and throughput are taken into consideration, n782TX+n1TX is concurrent, at the moment, MHB PA power supply is switched to BUCK APT, APT/ET1 supplies power to N78 PA0, APT/ET0 supplies power to N78 PA1, namely uplink data is transmitted in a mode of realizing 2TX or 3TX in N78 downlink time slots and uplink time slots; when the terminal is in the vicinity of the cell, the uplink common coverage area of n1 and n78, the terminal can select n1 1TX and n78 2TX according to the traffic to perform uplink transmission. n78 downlink time slots, APT/ET0 supplies power to MHB PA; n78 uplink time slots, APT/ET0 supplies power to N78 PA1, and APT/ET1 supplies power to N78 PA 0.

In the embodiment of the application, whether the terminal supports super uplink is judged so as to determine whether the terminal can perform uplink transmission by using super uplink technology.

And 106, if the terminal supports super uplink, judging whether the uplink signal strength value is greater than a second threshold value.

In the embodiment of the application, whether the signal strength value is larger than the second threshold value, namely the signal strength value at R1-delta is determined by continuously monitoring the RSP and the RSRP.

The radio frequency signals may include LTE signals, NR signals, etc., and the power amplifier amplifies the uplink signals, and then radiates the uplink signals into the air via the antenna for uplink transmission.

Furthermore, the method is realized based on PMIC and ET, simultaneously supplies power to a plurality of power supplies and is realized by combining network algorithm scheduling. The system can be expanded to ENDC combined power supply, such as LB+MHB combination, and the performance deterioration or cost increase caused by the complex scene can be improved through different power supply networks due to the scenes such as antenna switching or reverse connection and the like caused by the power supply problem.

Referring to fig. 10, fig. 10 is a flowchart of another signal transmission control method, in which in step S01, a terminal randomly accesses a master node and resides by searching for a broadcast signal; the main node of the network node provides control plane connection with the core network, the terminal enters a UE Capability flow, i.e. the UE Capability is reported, and the UE Capability comprises: UE Capability request and UE Capability report. When the base station needs the UE to report the UE Capability, the base station can send a UE Capability Enquiry instruction to the UE. And after receiving the UE capability information instruction, the UE reports the UE capability information according to the instruction. The base station knows the UE capabilities before it can make the correct scheduling for the UE. If the UE supports a certain function, the base station may configure the function for the UE; if the UE does not support a certain function, the base station may not configure the function for the UE.

Step S02, the terminal determines to support carrier aggregation through reporting, if not, the auxiliary node is not configured, and only the main node is used as a service.

If the terminal supports carrier aggregation, step S03 is entered, and an auxiliary node is added to the terminal. The secondary node may be activated based on the measurements or may be activated by blind addition.

Further, after adding the auxiliary node, step S04 is entered by: the SRS and the RSRP determine the uplink signal strength value of the terminal. If the uplink signal strength value is smaller than the first threshold value, the terminal is judged to be at a far point, and at the moment, FDD 1TX transmission is used for uplink.

If the uplink signal strength value is greater than the first threshold, step S05 is performed to determine whether the terminal supports super uplink, so as to determine whether the terminal can perform uplink transmission by using super uplink technology. If the super uplink transmission is not supported, uplink FDD1TX+TDD 1TX transmission is used.

If the super uplink is supported, the process proceeds to step S06, where the super uplink is activated.

In step S07, by continuously monitoring RSP and RSRP, it is determined whether the signal strength value is greater than the second threshold, that is, the signal strength value at R1- δ, if the uplink signal strength value is greater than the second threshold, it indicates that the terminal is in the area within (R1- δ), and at this time, the signal of the terminal is better, and TDD uplink coverage can meet the communication requirement of the terminal, so that at this time, FDD1tx+tdd2TX time division transmission can be adopted. After the uplink transmission is completed, the flow proceeds to S11, and the next round of transmission mode selection is prepared.

When the uplink signal strength value is greater than the first threshold and less than the second threshold, indicating that the terminal is currently in the middle zone of FDD and TDD uplink coverage, step S08 is performed at this time, and TDD2TX transmission is activated.

S09, judging whether an interference signal exists, if not, entering a step S10, and simultaneously carrying out uplink transmission by three paths of transmission channels, namely FDD1TX+TDD2TX, so as to improve the uplink transmission power of the terminal when the terminal is in an intermediate zone. If there is interference, FDD1TX+TDD2TX time division transmission is used.
