Detailed Description

First, a system architecture of an embodiment of the present application will be briefly described with reference to fig. 1, and fig. 1 is a system schematic diagram of a signal amplifying method provided by an embodiment of the present application, as shown in fig. 1:

including a network device 101, a terminal device 102, and a first device 103.

The network device 101 is an entity on the network side for transmitting or receiving signals, and may be, for example, a Base Station (BS) in a global system for mobile communications (Global System for Mobile Communications, GSM) or code division multiple access (Code Division Multiple Access, CDMA), or a Base Station NodeB in wideband code division multiple access (Wideband Code Division Multiple Access, often abbreviated as W-CDMA), or an evolved Base Station eNB, gNB in long term evolution (Long Term Evolution, LTE), which is not limited to a specific implementation manner of the network device 101.

The terminal device 102 may be a mobile terminal, a mobile user device, a computer device, a tablet computer, a smart phone, or the like, or the mobile terminal may also be a mobile phone (or referred to as a "cellular" phone), an in-vehicle processing device, or a computer with mobility, for example, a portable computer, a pocket computer, or a handheld computer, etc., which is not limited to the embodiments of the present application.

It should be noted that, the embodiment of the present application may be applied to a 5G communication system, or may also be applied to any other communication system such as 4G, 3G, etc., as long as the communication system includes a network device and a terminal device, where the network device and the terminal device may perform information interaction through a wireless signal.

In particular, in a wireless communication system, such as a New Radio (NR) communication system, information interacted between a terminal device and a network device is carried over a physical channel. Wherein, the data sent by the terminal device, namely uplink data, is usually carried by a physical uplink shared channel (physical uplink shared channel, PUSCH); the control information sent by the terminal device, i.e. uplink control information, is typically carried by a physical uplink control channel (physical uplink control channel, PUCCH). In addition, the terminal device may also transmit sounding reference signals (sounding reference signal, SRS), and the network device may estimate the channel quality of the terminal device on different frequencies by receiving the SRS of the terminal device. Accordingly, the data transmitted by the network device to the terminal device may be referred to as downlink data.

In a wireless communication system, the path loss of wireless signal propagation is very serious for some deep coverage scenarios, such as cell edges, or basements, etc. In this case, coverage enhancement needs to be considered for the wireless signal, because when the terminal device performs uplink data transmission, its transmission power tends to be low, so that the uplink signal transmitted by the terminal device in the deep coverage scenario is very weak when reaching the network device, and it is difficult for the network device to correctly detect or demodulate the uplink signal transmitted by the terminal device, so that coverage enhancement for the uplink wireless signal is particularly important.

Specifically, the first device 103 is disposed in an area where coverage enhancement is required in the wireless communication system to amplify and forward signals sent by the network device and/or the terminal device, so that the coverage enhancement effect on the signals can be effectively played, where the first device 103 is an entity capable of receiving signals and forwarding the received signals, or may be a terminal device with a capability of receiving and forwarding, specifically, the first device 103 may be, for example, a repeater, a relay, a special terminal device (a special device with a function of receiving signals and forwarding signals), etc., it is to be understood that the implementation manner of the embodiment is not limited in particular as long as the first device 103 can amplify and forward the received signals.

Referring to fig. 1, a network device 101, a terminal device 102, and a first device 103 constitute a communication system. In the communication system, the terminal device 102 may transmit uplink data to the network device 101, and the network device 101 may transmit downlink data to the terminal device 102. Downstream data sent by the network device 101 may also be forwarded to the terminal device 102 by the first device 103, while upstream data sent by the terminal device 102 may also be forwarded to the network device 101 by the first device 103. It can be considered that in the communication system, the network device 101 may transmit downlink information to the terminal device 102, the first device 103 may also transmit downlink information to the terminal device 102, and the first device 103 may also receive uplink information transmitted by the terminal device 102.

The first device in the communication system may be a repeater or a relay device.

The working principle of the repeater is briefly described below. The repeater can receive the downlink signal sent by the network equipment through the forward antenna, and the downlink signal is sent to the terminal equipment through the backward antenna after filtering, noise reduction and signal amplification. The repeater may also amplify and transmit the uplink signal transmitted by the terminal device to the network device in a similar manner.

Next, the working principle of the relay is briefly introduced, the relay can receive the downlink signal of the network device through the forward antenna, demodulate and/or decode the received downlink signal to obtain an original bit stream, then re-modulate and/or encode the original bit stream, and send the original bit stream to the terminal device through the backward antenna. The relay may also amplify and transmit the uplink signal transmitted by the terminal device to the network device in a similar manner.

Either the repeater or the relay may amplify and transmit one of the uplink signal and the downlink signal, or may amplify and transmit both the uplink signal and the downlink signal.

However, in the prior art, whether the first device is a repeater or a relay, the first device is in a continuously activated state after the first device is powered on, that is, for a wireless signal received by the first device, whether the wireless signal needs to be amplified or not, the first device always amplifies the received signal. Specific implementation manners of the uplink signal and the downlink signal are described below with reference to fig. 2A and fig. 2B, where fig. 2A is a schematic diagram of amplifying the uplink signal provided by the embodiment of the present application, and fig. 2B is a schematic diagram of amplifying the downlink signal provided by the embodiment of the present application.

An implementation manner in which the first device amplifies the uplink signal will be described first with reference to fig. 2A.

Referring to fig. 2A, the terminal device 1-2 of the present cell does not currently transmit an uplink signal, and the terminal device 2-1 of the neighboring cell transmits an uplink signal, wherein the uplink signal transmitted by the terminal device 2-1 may be directly transmitted to the network device 2. However, since the first device 0 that amplifies bi-directionally (i.e. amplifies both the downlink signal and the uplink signal) is always in an active state, the first device still amplifies the same-frequency uplink signal from the terminal device 2-1 in the neighboring cell, and thus, the uplink signal in the cell is interfered, even if there is no uplink signal that needs to be amplified in the current cell.

Meanwhile, in fig. 2A, since the terminal device 1-1 is far from the first device 0, the uplink signal transmitted by the terminal device 1-1 may be directly transmitted to the network device 1 without passing through the first device 0 at this time, that is, the network device 1 may receive the uplink signal directly transmitted by the terminal device 1-1.

An implementation manner in which the first device amplifies the downlink signal is described below with reference to fig. 2B.

Referring to fig. 2B, the network device 1 may directly send a downlink signal to the terminal device 1-2, and because the network device has a higher transmission power, the downlink channel of the cell in which the network device 1 is located does not need to be coverage-enhanced, but because the first device 0 is always in an active state, it amplifies all received signals, thereby amplifying the same-frequency downlink signal sent by the base station 2 from the neighboring cell, and it may cause interference to the downlink signal received by the terminal device 1-2.

When the first device is in an active state, the first device always unconditionally amplifies the received signal, which may result in that the received signal is still amplified in some time when signal amplification is not needed, so that interference suffered by the network device and the terminal device is increased, and communication quality is reduced.

Aiming at the problems in the prior art, the embodiment of the application provides a signal amplifying method which can effectively improve the communication quality. The signal amplifying method provided by the embodiment of the present application is described below with reference to fig. 3. Fig. 3 is a flowchart of a signal amplifying method according to an embodiment of the present application. The following embodiments are described by taking a time division duplex (Time Division Duplex, TDD) system as an example. The implementation of the frequency division duplex (Frequency Division Duplex, FDD) system is similar to that described in the TDD system, and this embodiment will explain the differences, and the other implementations are similar, and the implementation for the FDD system is similar to that of the TDD system and will not be described.

As shown in fig. 3, the method includes the following steps.

S301, acquiring indication information, wherein the indication information is used for indicating a first time length.

The method provided in this embodiment may be performed by the first device, or may be implemented by a chip in the first device, for example, a baseband processor, or a baseband processor and a radio frequency unit together. When the method provided in this embodiment is implemented by the baseband processor, the above-mentioned receiving operation may be understood as an operation of decoding the received signal to obtain the indication information, or may be understood as an operation of reading the signal input by the radio frequency unit.

When the above method is implemented by the baseband processor and the radio frequency unit together, the above receiving operation may be understood as an operation that the radio frequency unit receives a signal and performs down-conversion processing on the received signal, and the baseband processor decodes a signal output by the radio frequency unit to obtain the indication information.

The execution body in the present embodiment will be described by taking the first device as an example.

In the present embodiment, the indication information is used to indicate a first period (first period). The indication information may be indicated in various manners only for the first duration, for example, by carrying identification information corresponding to the first duration in the message, or directly sending the first duration in the message. The present embodiment is not limited to this, and may be specific as long as the indication information can indicate the first time length.

In one possible implementation, the indication information may be sent by the network device, or may also be sent by the terminal device, specifically, radio resource control (radio resource control, RRC) signaling sent by the network device/terminal device to the first device in real time, so as to configure the first duration.

The first duration may be configured for N slots, subframes, frames, milliseconds, seconds, etc., e.g., through RRC signaling. In an alternative embodiment, for a TDD system, since there is an uplink and downlink switching period, the first duration may also be in units of uplink and downlink switching periods, such as the first duration is N uplink and downlink switching periods, where N is an integer,

in another possible implementation manner, the indication information may be pre-agreed between the first device and the network device/terminal device through a protocol, for example, the first duration is pre-agreed between the first device and the network device terminal device through a protocol is 10 ms, and then the indication information is directly obtained from the agreed protocol.

Or, a plurality of first time periods may be pre-agreed between the first device and the network device terminal device, where each first time period corresponds to a respective identifier, and at this time, the indication information may indicate the identifier corresponding to the first time period, so as to determine the target first time period.

The specific implementation manner of the indication information is not limited in this embodiment, so long as the indication information can indicate the first time length, and the specific implementation manner of the first time length is also not limited in this embodiment, so long as the first time length is a period of time.

S302, when a first reference signal sent by the network equipment is detected, amplifying the first signal received in the first duration to obtain a second signal.

In this embodiment, the first device amplifies the signal received in the first time period, and does not amplify the signal received in other time periods than the first time period.

In this embodiment, the network device may further send a first reference signal to the first device, where the first reference signal is used to trigger the first device to amplify a signal received in the first duration. It will be appreciated that the first device may detect a plurality of first reference signals, wherein different first reference signals may be amplified respectively corresponding to different signals, such that the first device may put a signal corresponding to the first reference signal based on the detected first reference signals. The different signals may be signals of different frequency bands, or uplink signals and downlink signals, or signals corresponding to different services, and the like.

In one possible implementation, the indication information is used to indicate that the first device corresponds to a first duration, and the first device detects multiple first reference signals corresponding to the same first duration, for example, the first duration is 20 ms, when the first reference signal a is detected, the received uplink signal may be amplified within the next 20 ms from the time when the first reference signal a is detected, and when the first reference signal B is detected, the received uplink signal may be amplified within the next 20 ms from the time when the first reference signal B is detected.

In another possible implementation manner, the indication information is used to indicate the first duration corresponding to the first reference signal, that is, the different first reference signals correspond to respective indication information, and thus correspond to respective first durations. For example, when the first device detects the first reference signal C, it first determines that the first duration corresponding to the first reference signal C is 30 frames (frames) according to the indication information corresponding to the first reference signal C, then the first device may amplify the received first signal in 30 frames next to the time when determining the first duration, when detecting the first reference signal D, first determines that the first duration corresponding to the first reference signal D is 20 frames according to the indication information corresponding to the first reference signal D, and then the first device may amplify the received first signal in 20 frames next to the time when determining the first duration.

In an alternative embodiment, a predefined first time interval may also exist between the first reference signal and the first time period, and the first device amplifies the received uplink signal in the first time period after receiving the first reference signal and passing the first time interval, so that the first device has more sufficient starting time of hardware devices, and amplification quality is ensured.

In this embodiment, the first reference signal may be a reference signal generated in any manner, for example, may be a reference signal generated based on a Gold sequence, and specifically, different reference signals may be generated by different initial phases; or may be a reference signal generated based on a Zadoff-Chu, ZC sequence, specifically, different reference signals may be generated through different roots or cyclic shifts, and the embodiment of the present application does not limit a specific implementation manner of generating the first reference signal.

Those skilled in the art will understand that the first device that receives the first reference signal is in an active state for a first period of time, and the first device in the active state may amplify and transmit the received first signal; if the first device does not receive any first reference signal, the first device keeps the deactivated state, the first device in the deactivated state does not receive and amplify the forwarded signal, and the first device is set to a first duration for amplifying the first signal, so that interference caused by amplifying any received signal by the first device is avoided, but it should be noted that the explanation of the activated state is only for convenience of understanding, and in an actual implementation process, the action of setting the first device to the activated state may not exist.

In an alternative embodiment, the first reference signal may also be sent by the terminal device, where the specific implementation manner of the first device is similar to that described above, and will not be repeated herein.

S303, sending a second signal.

The first device transmits the amplified second signal. Specifically, if the first signal is an uplink signal sent by the terminal device, the first device uplink-sends the second signal obtained by amplification to the network device; if the first signal is a downlink signal sent by the network device, the first device sends the second signal obtained by amplification to the terminal device.

In the signal amplifying method provided by the embodiment, the first device determines the first duration according to the indication information, so that the first device amplifies and transmits the received first signal within the first duration, thereby avoiding that the first device amplifies all the received signals whenever the first device amplifies, effectively reducing interference generated within the time when the signal is not required to be amplified, and improving communication quality.

On the basis of the embodiment, the first signal which can be received in the first time period is set to be amplified, and in an actual communication network, an uplink signal can be amplified, and a downlink signal is not amplified; alternatively, it is also possible to amplify the downstream signal and not amplify the upstream signal. Or the signals of the specific time period in the first time period can be amplified, and the signals of other time periods can be not amplified. Thus, in addition to setting the first time period, the first time period may be set so as to indicate that those times within the first time period are periods during which amplification of the first signal is actually required, thereby enabling selective amplification of only the first signal that is required to be amplified.

In a possible implementation manner, the indication information provided in this embodiment is further used to indicate a first period (duration) in the first duration, and specifically when the received first signal is amplified, the first signal received in the first period in the first duration is amplified.

For example, an arbitrary number of first time periods may be divided into first time periods according to actual requirements, where the time periods corresponding to the first time periods may be the same or different, and the specific number of the first time periods and the time period corresponding to the first time periods may be selected according to actual requirements, which is not limited in this embodiment.

According to the embodiment, the indication information is used for indicating the first time period in the first time period, so that the first equipment can be indicated to amplify the received first signal in the appointed first time period according to actual requirements, and the accuracy and flexibility of the first equipment in amplifying the first signal are improved.

In another possible implementation manner, the indication information is further used for indicating a first period and a first period, where the first period includes at least one first period, and each first period includes the first period, and specifically when the received first signal is amplified, the first signal received in the first period in each first period in the first period is amplified.

By setting the first period and the first period, the signal in the first period can be amplified periodically, and the description will be given below with reference to fig. 4, where fig. 4 is a schematic diagram of a period of the signal amplifying method according to the embodiment of the present application.

Specifically, referring to fig. 4, the relationship between a first period and a first period is indicated by the corresponding indication information 1 of the first reference signal 1 in the exemplary embodiment of fig. 4, it can be seen from fig. 4 that the first reference signal 1 indicates that the first device amplifies the first signal received in the first period in each of the first periods, while referring to fig. 4, it can be understood that the horizontal axis indicates time, the vertical axis indicates the amplification factor of the first signal, the first reference signal is received at time t1, the received first signal is amplified in the first period according to the first reference signal, specifically, the received signal is amplified in the range of the duration corresponding to each first period, and the received signal is not amplified outside the first period and the period outside each first period in the first period.

In the actual implementation process, different first reference signals may correspond to respective first periods and first time periods, so fig. 4 also exemplarily further describes another correspondence between first periods and first time periods indicated by the first reference signal 2 corresponding to the indication information 2, which corresponds to similar implementation manners when amplifying the first signals, but different divisions of the first periods and the first time periods, and it will be understood by those skilled in the art that specific first periods and first time periods may be selected according to actual requirements, which is not limited herein, and signals in different time periods may be correspondingly amplified by dividing different first periods and first time periods.

According to the method and the device for amplifying the first signals, the indication information is arranged to indicate the first period and the first time period, so that the first signals in the first time period can be periodically amplified, each first time period required to amplify the first signals does not need to be independently arranged for periodic amplification, the simplicity of amplifying the first signals by the device is enhanced, and meanwhile, the first signals in the first time period required to be amplified can be only amplified by the device, and the accuracy of amplifying the first signals by the first device is enhanced.

On the basis of the above embodiment, the first period in the first period is an uplink period and/or a downlink period in the first period, and the description is given below with reference to fig. 5, and fig. 5 is a second period schematic diagram of the signal amplifying method provided by the embodiment of the present application.

Specifically, the first period may be an uplink/downlink switching period, referring to fig. 5, where an uplink/downlink switching period includes an uplink period (UL) and a downlink period (DL), and the corresponding first period may be an uplink period, and the corresponding first device amplifies the first signal in the uplink period and does not amplify the signal in other time, so as to amplify only the uplink signal; or the corresponding first time period can be a downlink time period, and the corresponding first equipment only amplifies the first signal in the downlink time period, so that the effect of only amplifying the downlink signal is achieved; alternatively, the first period may include both an uplink period and a downlink period, and all signals received in the first period may be amplified at this time.

In a possible practical scenario, when the terminal device sends an uplink signal to the network device, because the sending power of the terminal device is often lower, the signal of the uplink signal sent by the terminal device is very weak when the uplink signal arrives at the network device, and only the first signal in the uplink period can be amplified at this time, so that the weak uplink signal sent by the terminal device to the network device can be amplified in a targeted manner.

In this embodiment, because the transmission intensities of the uplink signal and the downlink signal are often different, the degrees of amplification required by the uplink signal and the downlink signal are also different, and the respective amplification factors of the uplink period and the downlink period may be indicated by correspondingly setting the indication information corresponding to each first reference signal, so as to realize different amplification factors in different periods.

According to the embodiment, the first time period in the first period is set as the uplink time period and/or the downlink time period in the first period, so that the uplink signal and/or the downlink signal can be flexibly configured and amplified, weak useful signals are amplified in a targeted manner, communication interference is reduced, and communication quality is improved.

It should be noted that, if the indication information does not indicate any first period, all the received first signals are amplified by default within the time range of the first duration.

On the basis of the above embodiment, when uplink signal transmission or downlink signal transmission is performed, it is likely that only a part of the full bandwidth of the network device is used to perform signal transmission, and all that is required is to receive and amplify the first signal under the bandwidth corresponding to the actually transmitted frequency range, and at this time, amplifying the first signal in another frequency range may increase interference of the signal, so in this embodiment, the correspondence between the first reference signal and the specific frequency range may be set, so that when the first device receives a different first reference signal, only the first signal in the frequency range corresponding to the first reference signal may be received and amplified.

Specifically, in this embodiment, the indication information further indicates a frequency range, and specifically when the received first signal is amplified, the received first signal in the frequency range in the first time period is amplified.

Fig. 6 is a schematic diagram of a frequency range of a signal amplifying method according to an embodiment of the present application.

Assuming that the indication information 1 corresponding to the first reference signal 1 indicates the frequency range 1, the indication information 2 corresponding to the first reference signal 2 indicates the frequency range 2, and the indication information 3 corresponding to the first reference signal 3 indicates the frequency range 3, the indication information 1 corresponding to fig. 6 indicates that the first signal received in the frequency range 1 is amplified in the first duration, where the horizontal axis of coordinates in fig. 6 is frequency.

Specifically, the frequency ranges indicated by the indication information may overlap or may not overlap with each other, which is not limited in this embodiment, where the frequency range corresponding to the indication information may be selected according to the actual requirement, which is not limited in this embodiment.

It should be noted that, if the indication information does not indicate any frequency range, the first signals received in all frequency ranges may be amplified by default in the time range of the first duration; alternatively, the first signals received within the operating frequency range of the network device may be amplified.

According to the embodiment, the indication information is set to indicate the frequency range, so that the first signal in a part of the frequency range can be selectively amplified, the amplification of the signal in the frequency range without amplification is avoided, and the interference in the communication process is reduced.

On the basis of the above embodiment, the signal amplifying method provided by the embodiment of the present application may further specifically indicate an amplifying degree of amplifying the first signal.

Specifically, the indication information further indicates power indication information, where the power indication information may indicate an absolute power value at which the second signal is transmitted, for example, the power indication information indicates that the first device transmits the second signal according to 29 dBm; alternatively, the power indication information may also indicate a power amplification factor by which the first signal is amplified, e.g. the power indication information indicates that the first signal is amplified by a factor of 10 (i.e. 10 dB) to obtain the second signal.

In one possible implementation, the power indication information may also be information configured separately from the indication information, that is to say that the power indication information and the indication information are two separate pieces of information, wherein the power indication information is dedicated to indicating an absolute power value or a power amplification factor at which the first signal is amplified.

In an alternative embodiment, if the indication information does not indicate power indication information, or the first device does not receive power indication information, the first signal may be amplified according to a predefined absolute power value or power amplification factor.

Based on the foregoing embodiments, a detailed description of a specific implementation of the first reference signal in this embodiment is provided below in conjunction with table 1.

Specifically, the first reference signal in this embodiment is determined according to first reference signal configuration information, where the first reference signal configuration information includes one or more of first sequence information, first frequency domain candidate resource information, and first time domain candidate resource information.

The first reference signal configuration information may be information independent of the indication information, or the first reference information may also be one piece of information in the indication information, which is not limited in this embodiment.

The contents included in the first reference signal configuration information are described below with reference to table 1:

table 1:

the first reference signal identifier is used for uniquely indicating a first reference signal, where a specific implementation manner of the first reference signal identifier may be selected according to actual needs, which is not limited in this embodiment.

The first sequence information is used to indicate a sequence of the first reference signal, and specifically, the first sequence information may be, for example, a sequence generated based on a Gold sequence as in the above embodiment, or may be a sequence generated based on a Zad-off Chu (ZC) sequence.

The first frequency domain candidate resource is used to instruct the first device to detect the frequency domain resource of the first reference signal, and the first time domain candidate resource is used to instruct the first device to detect the time domain resource of the first reference signal, which is understood to be a signal, which corresponds to a period and a frequency range of transmission, so that the first frequency domain candidate resource actually indicates a frequency range in which the first reference signal may occur, and the first time domain candidate resource actually indicates a time domain position in which the first reference signal may occur.

In the actual implementation process, the network device may configure one or more first reference signals for the first device, so that the first device may determine a specific first reference signal according to the identifier of the first reference signal, and detect the first reference signal in the frequency domain resource range indicated by the first frequency domain candidate resource and in the time domain resource range indicated by the first time domain candidate resource according to the first frequency domain candidate resource and the first time domain candidate resource of the first reference signal, thereby avoiding energy consumption and complexity overhead caused by large-scale blind detection, and improving efficiency and accuracy of detecting the first reference signal.

On the basis of the above embodiment, in addition to the first reference signal for triggering the first device to amplify the signal received in the first duration, the embodiment of the present application further provides a second reference signal for triggering the signal received by the first device to stop amplifying, and the implementation manner of the second reference signal is described below with reference to fig. 7, and fig. 7 is a second flowchart of the signal amplifying method provided by the embodiment of the present application.

As shown in fig. 7, the method further includes:

s701, receiving a second reference signal.

In particular, the second reference signal is similar to the implementation of the first reference signal, except that the second reference signal is used to trigger the signal received by the first device to stop amplifying, and those skilled in the art will understand that the second reference signal is used to set the first device to a deactivated state.

In this embodiment, the second reference signal is determined according to second reference signal configuration information, where the second reference signal configuration information includes one or more of second sequence information, second frequency domain candidate resource information, and second time domain candidate resource information;

The implementation manner of the second reference signal configuration information and the first reference signal configuration information is similar, and the specific implementation manner thereof may refer to the description in the above embodiment, which is not repeated here.

In an alternative implementation, the second reference signal may be a signal corresponding to the first device, that is to say that the first reference signals of the first device all correspond to the same second reference signal; alternatively, the second reference signals may be signals corresponding to the first reference signals, i.e. the first reference signals of the first device correspond to the respective second reference signals.

S702, according to the second reference signal, stopping amplifying the received signal.

When the second reference signal is received, the amplification of the received signal needs to be stopped, but as to when the amplification of the signal is to be stopped in particular, the stop time needs to be determined according to the second reference signal.

Specifically, determining a stop time according to the second reference signal, wherein the stop time is a smaller value in a first end time and an end time of a first duration corresponding to the second reference signal; the first device starts at a stop time and stops amplification of the received signal.

That is, the stopping time is the first ending time, or the stopping time is the ending time of the first time, the two implementations are described below with reference to fig. 8 and fig. 9, respectively, fig. 8 is a schematic diagram one of the stopping and amplifying signal provided by the embodiment of the present application, and fig. 9 is a schematic diagram two of the stopping and amplifying signal provided by the embodiment of the present application:

as shown in fig. 8, the first reference signal 1 corresponds to a first duration 1, the first reference signal 2 corresponds to a first duration 2, the first reference signal 3 corresponds to a first duration 3, on a time axis, that is, on a horizontal axis, an end time corresponding to the first duration 1 is t1, an end time corresponding to the first duration 2 is t2, an end time corresponding to the first duration 3 is t3, and a first end time corresponding to the second reference signal is t 4.

It will be appreciated that the situation illustrated in fig. 8 is actually that the amplification of the received signal is stopped after the first time period indicated by each indication information has ended, and that in the situation illustrated in fig. 8, the second reference signal is not actually needed.

As shown in fig. 9, according to the correspondence relationship of each time point on the time axis, it can be determined that the first end time is the minimum value of t4 compared with the end time of the first duration, and the first device stops amplifying the received large signal from the time t 4.

In a possible implementation manner, a predefined second time interval may also exist between the second reference signal and the end time, and after the second time interval elapses after the first device receives the second reference signal, the first device stops amplifying the received uplink signal, so that the first device has a more sufficient hardware device closing time, and device damage caused by abrupt changes of current or voltage is prevented.

It will be appreciated that the situation illustrated in fig. 9 is actually that after the second reference signal is received, whether or not the first time period indicated by each indication information is ended, amplification of the received signal is stopped in direct response to the second reference signal.

Alternatively, in another possible manner, the first duration may be configured to be infinity by the indication information, that is, after the first reference signal is received, the received reference signal is continuously amplified until the second reference signal is received, and the amplifying and transmitting of the received first signal is stopped.

The signal amplifying method provided in this embodiment includes: a second reference signal is received. And stopping amplifying the received signal according to the second reference signal. According to the second reference signal, the amplification of the received signal is stopped, so that the amplification of the signal can be accurately and effectively stopped, whether the first signal is amplified or not can be flexibly and effectively realized, interference generated in the time when the signal is not required to be amplified is effectively reduced, and the communication efficiency is improved.

In summary, the foregoing embodiments are described, and in exemplary embodiments, a complete indicator may include the following:

indication information = { first reference signal identification, first duration, first period, frequency range, power indication information, second reference signal identification }

And the first equipment detects the first reference signal in the frequency domain resource of the first reference signal and the time domain resource of the first reference signal according to the first reference signal identification in the indication information, and after the first reference signal is detected, the first equipment is triggered to amplify the signal received in the first duration, specifically, the first signal in the frequency range is amplified in the first duration, the first signal is amplified to an absolute power value indicated by the power indication information, or the first signal is amplified according to the amplification factor indicated by the power indication information, so as to obtain the second signal and send the second signal.

Meanwhile, the second reference signal is detected according to the second reference signal identifier, and after the second reference signal is detected, the amplification of the received signal is stopped according to the second reference signal.

Meanwhile, the network device may configure the first device with a plurality of the above-described indication information:

{ indication information 1, indication information 2, indication information 3}

If any of the indication information is not configured, it can be understood as predefined, and no notification or configuration is required.

In the following, a specific implementation process is taken as an example to fully describe the signal amplifying method provided in this embodiment, fig. 10 is a schematic diagram of amplifying a signal of uplink data provided in the embodiment of the present application, and fig. 8 is a schematic diagram of stopping amplifying a signal provided in the embodiment of the present application, as shown in fig. 10:

the network device sends a first reference signal to the first device, after the first device receives the first reference signal, the first device determines indication information corresponding to the first reference signal, amplifies the received first signal according to each item of content indicated by the indication information, and supposes that the indication information at the moment indicates to amplify the first signal received in the uplink time period.

For example, at time t1, the network device schedules the terminal device to transmit uplink data through the PUSCH, specifically, the network device sends downlink control information (Downlink Control Information, DCI) to the terminal device, so as to instruct the terminal device to send uplink data to the network device through the PUSCH according to DCI signaling, specifically, the first device receives a first signal (uplink signal) sent by the terminal device, amplifies the first signal to obtain a second signal, and sends the second signal to the network device, and the network device can receive the amplified second signal, thereby effectively solving the problem of signal attenuation caused by lower transmission power of downlink data and uplink data in a deep coverage scene, and meanwhile, the first device amplifies the uplink signal only in a first duration, thereby realizing only amplifying the uplink signal required and avoiding interference generated by amplifying all signals.

On the basis of the above embodiments, differences between the FDD system and the TDD system are described below:

for a TDD system, since uplink transmission and downlink transmission are performed on the same frequency band according to time cross allocation, in the TDD system, only uplink signal amplification or only downlink signal amplification can be achieved by configuring only an uplink period or a downlink period, but for a frequency division duplex (Frequency Division Duplex, FDD) system, since uplink transmission and downlink transmission of the FDD system are distinguished in different frequency ranges, in the FDD system, the effect of "only uplink amplification" or "only downlink amplification" cannot be achieved by setting only the uplink period or the downlink period.

Therefore, for the FDD system, an uplink frequency band or a downlink frequency band needs to be set separately, so as to instruct how to amplify the first signal specifically, the indication information corresponds to the frequency band to be amplified, and the indication information needs to correspondingly instruct whether the amplified frequency band is the uplink frequency band or the downlink frequency band.

Specifically, the indication information is further used for indicating frequency band information, where the frequency band information may be an uplink frequency band or a downlink frequency band, and the indication information in the FDD system may be as follows:

in the configuration information, information of DL or UL frequency bands is included, for example:

indication information = { first reference signal identification, first duration, first period, uplink or downlink frequency band, frequency range, power indication information, second reference signal identification }

In summary, according to the embodiment, through flexible configuration and on-demand activation of the working interval of the first device, cell coverage is effectively improved, useless amplification of the first device is avoided, and therefore energy consumption and interference are reduced.
