Technical Field

The present application belongs to the field of communication technology, and specifically relates to a terminal radio frequency front-end structure and a terminal.

Background technique

At present, as the diversification of terminal functions continues to increase, the power requirements are also getting higher and higher. In order to improve the user experience, a low-power mode of the terminal is proposed. The terminal is in a standby state in the low-power mode, which can greatly reduce power consumption. After receiving the wake-up signal, the terminal resumes the normal working mode and sends and receives signals other than the wake-up signal.

However, the terminal in the related art needs to realize the low power consumption mode and the normal working mode through the same communication module. Thus, in the low power consumption mode, part of the transceiver hardware is idle, resulting in a waste of transceiver hardware resources.

The transceiver module is used for sending or receiving other signals besides receiving the wake-up signal;

N and M are positive integers, and N is greater than M.

In a second aspect, a terminal is provided, comprising the terminal radio frequency front-end structure as described in the first aspect.

In an embodiment of the present application, the transceiver module or the receiving module can be connected to M antennas through an antenna switching switch, so that in the low power consumption mode of the terminal, a receiving module dedicated to receiving wake-up signals can be started, avoiding the transceiver module from being connected to all antennas for signal reception and transmission, thereby reducing the consumption of transceiver hardware resources in the low power consumption mode of the terminal.

The terminal RF front-end structure and the terminal provided in the embodiments of the present application are described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

As shown in FIG2 , an embodiment of the present application provides a terminal radio frequency front-end structure, including:

A transceiver module 201, a receiving module 202, an antenna switch 203, and N antennas (only some of the antennas are shown in FIG. 2 );

Among them, M antennas among the N antennas are connected to the transceiver module 201 or the receiving module 202 through the antenna switching switch 203;

The receiving module 202 is used to receive a wake-up signal, where the wake-up signal is a low-power wake-up signal of the terminal;

The transceiver module 201 is used for sending or receiving other signals besides receiving the wake-up signal;

N and M are positive integers, and N is greater than M.

In this way, the terminal RF front-end structure of the embodiment of the present application can connect the transceiver module 201 or the receiving module 202 to M antennas through the antenna switching switch 203, so as to start the receiving module 202 dedicated to receiving the wake-up signal in the terminal low power consumption mode, avoid the transceiver module 201 from being connected to all antennas for signal reception and transmission, reduce the transceiver hardware resource consumption in the terminal low power consumption mode, and there is no need to add a dedicated receiving antenna for the wake-up signal, thereby saving costs.

In this embodiment, the low power consumption mode is a state in which the receiving module receives a wake-up signal, and the receiving module is connected to the M antennas through an antenna switching switch. The wake-up signal may also be referred to as a low power consumption wake-up signal.

As an implementation method, the receiving module is only used to receive the low-power wake-up signal of the terminal and has no sending function. Its power consumption is lower than that of the transceiver module as the main communication module, further reducing the power consumption of the terminal in the low-power mode.

Optionally, the transceiver module is further connected to at least one remaining antenna, and the remaining antenna is an antenna among the N antennas except the M antennas.

In this way, when the M antennas are connected to the receiving module through the antenna switching switch such as the antenna switching unit (Antenna Switch Module, ASM), the transceiver module can also be connected to at least one of the remaining NM antennas, that is, the transceiver module and the receiving module can work simultaneously in the low power consumption mode to meet the needs of sending and receiving signals other than the wake-up signal in the low power consumption mode; after the M antennas are connected to the transceiver module through the antenna switching switch, the number of transceiver module connections is greater than M antennas are connected to ensure that the performance does not decrease. Here, after the M antennas are connected to the transceiver module through the antenna switching switch, the number of antennas connected to the transceiver module is greater than or equal to M+1 and less than or equal to N.

Optionally, when the transceiver module is not connected to the M antennas, the transceiver module receives a downlink physical signal or a signal transmitted by a downlink physical channel through the at least one remaining antenna.

That is, when the receiving module is connected to the M antennas and receives the wake-up signal, the transceiver module works simultaneously to receive the downlink physical signal or the signal transmitted by the downlink physical channel through at least one remaining antenna connected.

Optionally, when the transceiver module is connected to the M antennas, the transceiver module sends or receives at least one of the following through the M antennas and/or the at least one remaining antenna:

Reference signal;

a synchronization signal or a synchronization signal block;

A signal transmitted via a random access channel;

Control channel transmission signals;

The data channel transmits information.

That is, the receiving module is not working and only the transceiver module is working. The transceiver module can transmit and receive at least one of the reference signal, synchronization signal or synchronization signal block, signal transmitted by random access channel, signal transmitted by control channel, and information transmitted by data channel through M antennas and/or at least one remaining antenna.

Among them, reference signals include but are not limited to: Sounding Reference Signal (SRS), Channel State Information-Reference Signal (CSI-RS), Phase Tracking Reference Signal (PTRS), Positioning Reference Signal (PRS), etc.

The control channels include but are not limited to: Physical Downlink Control Channel (PDCCH), Physical Uplink Control Channel (PUCCH), Physical Random Access Channel (PRACH). The signals transmitted by the control channels can also be understood as control signals.

The data channels include but are not limited to: Physical Uplink Shared Channel (PUSCH) and Physical Downlink Shared Channel (PDSCH).

It should be understood that in this embodiment, as shown in Figure 3, the transceiver module enters a closed or sleep state (the transceiver module is not connected to the M antennas) based on preset conditions. When the receiving module detects the wake-up signal sent by the transmitting end, the transceiver module is triggered/woken up (the transceiver module is connected to the M antennas), and data can be received and sent.

The wake-up signal includes information for waking up the terminal.

In addition, in this embodiment, a preset condition is predefined or configured to determine whether it is necessary to receive a wake-up signal, so as to determine whether to connect M antennas to the transceiver module or M antennas to the receiving module through the antenna switching switch. Therefore, optionally, when it is determined based on the preset condition that it is necessary to receive the wake-up signal, the M antennas are connected to the receiving module through the antenna switching switch;

The preset condition includes at least one of the following:

The transceiver module receives a control signal instructing the terminal to enter a low power consumption mode;

The transceiver module receives a control signal instructing the transceiver module to stop receiving or sending a preset signal;

The timer expires, and the timer is a timer that is triggered to run by receiving or sending a preset signal.

In this way, the terminal can connect the M antennas to the receiving module through the antenna switching switch, i.e., start the receiving module to start working, through the transceiver module and the antennas (greater than or equal to M) connected thereto, after receiving the first signal (a control signal instructing the terminal to enter a low power consumption mode) and/or the second signal (a control signal instructing the transceiver module to stop receiving or sending a preset signal). The terminal can also trigger a timer running by receiving or sending a preset signal, and after the timer expires, connect the M antennas to the receiving module through the antenna switching switch, i.e., start the receiving module to start working.

The preset signal is some special signal that is predefined or configured, such as a specific physical signal, a signal transmitted by a specific physical channel, etc. Of course, the preset signal can be sent or received by the transceiver module.

Optionally, when the M antennas are connected to the receiving module through the antenna switching switch, at least one of the following is performed:

If the receiving module receives the wake-up signal, the antenna switching switch switches the M antennas to connect to the transceiver module;

If the receiving module does not receive the wake-up signal, the antenna switching switch maintains the connection between the M antenna switches and the receiving module.

That is to say, when the receiving module is working, if a wake-up signal is received, that is, the terminal needs to exit the low-power mode, the antenna switching switch will switch the M antennas connected to the receiving module to be connected to the transceiver module, and stop the receiving module from working. At this time, the terminal enters normal mode (non-low-power mode) and can send or receive other signals except the low-power wake-up signal.

As an implementation method, the transceiver module may generally include at least one of the following items to realize the sending or receiving of other signals in addition to the reception of low-power wake-up signals: a radio frequency filter (RF filter), a switch (also called a transceiver switch (Switch between Tx and Rx)), a low noise amplifier (Low Noise Amplifier, LNA) and a power amplifier (Power Amplifier, PA).

The transceiver module in the terminal RF front-end structure can also reuse the above antenna switch or connect another antenna switch to select different working frequency bands; a matching network can also be set between the antenna switch and the antenna, and the matching network can flexibly realize the antenna impedance matching on different frequency bands to achieve the best performance of RF signal transmission and reception. The uplink transmission amplifies the transmission signal through the PA, and the downlink reception amplifies the reception signal through the LNA. In addition to the RF front-end part, the terminal can also include a transceiver and a baseband processing unit. The transceiver converts the RF signal to the baseband signal or converts the baseband signal to the RF signal through down-conversion or up-conversion, and processes it through the baseband processing unit.

Optionally, the transceiver module includes a transceiver unit on a time division multiplexing frequency band and a transceiver unit on a frequency division multiplexing frequency band.

Here, the transceiver unit is not an independent hardware structure, but is composed of multiple hardware structures. For example, the transceiver module includes a radio frequency filter, a duplexer, a switch, an LNA and a PA. When the antenna switch is switched to the frequency division duplex (FDD) band, a duplexer is used to realize simultaneous transmission and reception within the band. The device also has a radio frequency filtering function; when the antenna switch is switched to the time division duplexing (TDD) frequency band, after passing through an RF filter, a switch is used to select one of sending or receiving on the frequency band. Therefore, the transceiver unit on the time division duplexing frequency band is composed of at least an RF filter, a switch, an LNA and a PA; the transceiver unit on the frequency division duplexing frequency band is composed of at least a duplexer, an LNA and a PA. Among them, the two transceiver units can use their own LNA and PA independently, or they can share LNA and/or PA.

As an implementation method, the receiving module includes: an RF filter, an RF envelope detector, an LNA (such as a baseband amplifier) baseband filter, a comparator or an analog to digital converter (ADC), and a digital processing unit. In this way, the RF signal is received by the antenna, passes through a matching network, bandpass filtering, and then amplified by the LNA to obtain an amplified RF signal. After RF envelope detection, the RF signal is converted to a baseband signal. After amplification and low-pass filtering, the amplified baseband signal is obtained. Then, the analog signal is converted to a digital signal through a comparator or ADC, and digital processing is performed in the digital processing unit. Because the RF signal is converted to a baseband signal by using envelope detection, only the signal amplitude information is used, so it is more suitable for amplitude shift keying (ASK) modulation or binary amplitude keying (OOK) modulation.

As an implementation method, the receiving module includes: a radio frequency filter, a ring oscillator, a mixer, an LNA (such as an intermediate frequency amplifier, a baseband amplifier), an intermediate frequency filter, an intermediate frequency envelope detector, a baseband filter, a comparator or an ADC, and a digital processing unit. The radio frequency signal is received by the antenna, and after passing through a matching network and radio frequency bandpass filtering, it is mixed with the local signal generated by the ring oscillator to convert the radio frequency signal into an intermediate frequency signal. After amplification and intermediate frequency filtering, an amplified intermediate frequency signal is obtained. After intermediate frequency envelope detection, the intermediate frequency signal is converted into a baseband signal. After amplification and low-pass filtering, an amplified baseband signal is obtained. Then, through a comparator or an ADC, the analog signal is converted into a digital signal, and digital processing is performed in the digital processing unit. Because the radio frequency signal is converted into a baseband signal by using envelope detection, only the signal amplitude information is used, so it is more suitable for ASK modulation or OOK modulation.

Based on the characteristics of the above-mentioned terminal RF front-end structure, in order to support the terminal to receive the low-power wake-up signal at a lower power through the receiving module, the typical waveform or modulation method of the low-power wake-up signal is ASK or OOK, so that the receiving module does not need complex time-frequency domain transformation signal processing and other operations, and simply detects the amplitude information in the time domain to receive the low-power wake-up signal from the transmitter.

It should be noted that in this embodiment, the implementation of the above-mentioned transceiver module and receiving module is only one possible implementation, and there may be various implementation forms, such as the implementation of the transceiver switch in the transceiver module, etc. The present application will not list the specific implementation forms one by one.

Optionally, the transceiver module and the receiving module have different operating frequency bands.

In addition, in this embodiment, considering that both the transceiver module and the receiving module need to use devices such as radio frequency filters and low noise amplifiers, optionally, at least one device in the transceiver module and the receiving module is the same, and the at least one device includes:

RF filters;

Low noise amplifier.

In this way, when the M antennas are connected to the transceiver module or the receiving module through the antenna switching switch, Use RF filters and/or low noise amplifiers to reduce the complexity of the terminal RF front-end structure and save costs.

As an implementation method, when the transceiver module and the receiving module operate in the same frequency band, the same RF filter is used; otherwise, different RF filters are used.

Optionally, the transceiver module is at least one of the following:

NR terminal transceiver module, LTE terminal transceiver module, Narrow Band Internet of Things (NB-IoT) terminal transceiver module, Machine Type Communication (MTC) terminal transceiver module, NR side-link terminal transceiver module, LTE side-link terminal transceiver module, WIFI terminal transceiver module.

The application of the embodiments of the present application is described below in conjunction with specific scenarios:

As shown in Figure 4, the terminal RF front-end structure of the embodiment of the present application includes a transceiver module, a receiving module, an antenna switching switch (ASM-2 as shown in the figure) and 4 (N=4) antennas (Ant#0/1/2/3). ASM-2 can switch between the transceiver module and the receiving module. For the transceiver module, it includes a transceiver unit on the TDD frequency band and a unit on the FDD frequency band; for the receiving module, its operating frequency band can be different from that in the transceiver module.

Two (M=2) antennas Ant#2 and Ant#3 are connected to one of the transceiver modules or the receiver module through ASM-2.

When the receiving module is working, ASM-2 connects the receiving module with Ant#2 and Ant#3. Preferably, at least one of the other two antennas, Ant#0 and Ant#1, is connected to the transceiver module. For example, Ant#0 and/or Ant#1 are connected to the transceiver module through another antenna switching switch (ASM-1 as shown in the figure), at which time the receiving module and the transceiver module can work at the same time, and the wake-up module and the transceiver module are connected to the two antennas respectively. When the receiving module is not working, ASM-2 is connected to the transceiver module, at which time all antennas and transceivers can be connected.

Assume that only 2 receiving antennas need to be connected on band j and 4 receiving antennas need to be connected on band i.

In this way, as shown in Figure 4, Ant#2 and Ant#3 are connected to the transceiver module through ASM-2, and Ant#0 and Ant#1 are connected to the transceiver module through ASM-1, so that the terminal on Band i can support 4-antenna reception to support higher-order MIMO transmission. When the terminal turns on the receiving module, the typical scenario is that the terminal's business is not frequent at this time, or even there is no transceiver business for a period of time, and there is no need to maintain the state of receiving with 4 receiving antennas. At this time, 2 of the 4 antennas can be connected to the receiving module, and the other 2 antennas are still connected to the transceiver module. Although the transceiver module has only two antennas working, since the actual signal transmission is not frequent, or even there is no signal reception for a period of time, the performance degradation of only using 2 receiving antennas is also limited. In this way, the terminal can realize the simultaneous operation of the transceiver module and the receiving module without increasing the number of physical antennas.

Among them, when the transceiver module and the receiving module operate in different frequency bands, the transceiver module operates on band i, and the receiving module operates on band j, then the corresponding RF devices of the two modules are different, such as RF filters. As shown in Figure 4, when Ant#2 and Ant#3 are connected to the transceiver module, these two antennas are connected to RF filter-2 and RF filter-3 operating on band i. When Ant#2 and Ant#3 are connected to the receiving module, these two antennas are connected to RF filter-4 and RF filter-5 of band j. The LNA in the transceiver module and the receiving module is also an independent device. RF filter-4 and RF filter-5 are connected to LNA4 and LNA5 respectively.

Furthermore, when the transceiver and receiver modules operate on the same band, the RF components can be as Reuse. For example, both work on band i. When Ant#2 and Ant#3 are connected to the receiving module, the RF filter and LNA can be reused in the corresponding RF path. As shown in Figure 5, Ant#2 and Ant#3 are connected to the receiving module or the transceiver module. The corresponding RF paths are respectively connected to RF filter-2 and LNA2, and RF filter-3 and LNA3. In this structure, more devices can be shared. As antennas Ant#2 and Ant#3 switch between the two modules, the RF filter and LNA in the RF path are also switched between the two modules. The specific LNA and RF Filter connection switching method is not further described in this application.

In addition to the RF filter and LNA shown in Figures 4 and 5, which are completely switched between the transceiver module and the receiver module, only one of the RF filter and LNA can be switched between the two. As shown in Figure 6, although the transceiver module and the receiver module work in different frequency bands, the RF filter is not shared, but the LNA can be shared and switched between the two. When different transceiver modules and receiver modules work in different bands, the device is shared as much as possible.

In addition, even if the transceiver module and the receiving module operate in the same frequency band, the LNA between the two can be an independent device due to different design indicators. As shown in Figure 7, the difference from Figure 5 is that the RF filter between the two is still shared, but the LNA is an independent device. This method allows different design indicators to determine whether the LNA needs to be shared, which is more flexible.

It should also be noted that what is presented in FIG. 4-7 is only one possible implementation, and various implementation forms may be actually provided. For example, the receiving module further includes a ring oscillator, etc., which are not shown, and the transceiver module further includes a radio frequency envelope detector, etc., which are not shown, and are not listed one by one here.

In summary, the terminal RF front-end structure of the embodiment of the present application supports the simultaneous operation of the two modules by switching some antennas between the transceiver module and the receiving module without increasing the number of physical receiving antennas; when the receiving module is not working, the antenna and the transceiver module are connected to ensure that the transceiver module is connected to enough antennas after wake-up, and the performance will not decrease.

The terminal RF front-end structure in the embodiment of the present application is applied to the terminal, which may include but is not limited to the types of terminal 11 listed above, and other devices may be servers, network attached storage (NAS), etc., which are not specifically limited in the embodiment of the present application.
