Abstract

The application discloses a signal processing method and a related device. In the method, in response to the time interval between the wake-up signal and the synchronous signal being greater than or equal to the offset, the terminal device listens for the wake-up signal, and correspondingly, the network device sends the wake-up signal. Optionally, if the time interval between the wake-up signal and the synchronization signal is smaller than the offset, the terminal device does not monitor the wake-up signal, and correspondingly, the network device does not send the wake-up signal. Therefore, when the low-power consumption receiver processes the synchronizing signal and monitors the wake-up signal by adopting hardware with different precision, the terminal equipment can synchronize in time through the synchronizing signal without monitoring the wake-up signal when the time interval is smaller than the offset, so that larger timing deviation is avoided when the terminal equipment monitors the wake-up signal.

In order to better understand the technical solution of the present application for a person skilled in the art, the technical solution of the present application in the embodiment of the present application is described below with reference to the accompanying drawings in the embodiment of the present application. It will be apparent that the described embodiments are some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art to which the application pertains without inventive faculty, are intended to fall within the scope of the application.
Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the described embodiments of the application may be combined with other embodiments.
It should be noted that, in the present application, "first", "second", "third", etc. are used for distinguishing similar objects and not necessarily for describing a particular sequential or chronological order. Furthermore, the term "include" and any variations thereof are intended to cover a non-exclusive inclusion. For example, a process, method, software, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus. It should also be understood that the term "and/or" as used in this disclosure refers to and encompasses any or all possible combinations of one or more of the listed items.
The embodiment of the application provides a signal processing method 100, in the signal processing method 100, when a low-power consumption receiver processes a synchronizing signal and monitors a wake-up signal by adopting hardware with different precision, a terminal device can respond to a time interval between the synchronizing signal and the wake-up signal to monitor the wake-up signal to be larger than or equal to an offset, and avoid monitoring the wake-up signal when the time interval is smaller than the offset, thereby causing incapability of processing the synchronizing signal. That is, in the present application, if the time interval between the synchronization signal and the wake-up signal is smaller than the offset, the terminal device may not monitor the wake-up signal, and perform synchronization in time through the synchronization signal, so as to avoid a larger timing deviation when the terminal device monitors the wake-up signal.
The embodiment of the application also provides a signal processing method 200, in the signal processing method 200, the terminal equipment can determine a first time interval, monitor the wake-up signal outside the first time interval, and avoid that the wake-up signal is monitored in the first time interval, so that the synchronization signal cannot be processed. That is, in the present application, the terminal device may determine the first time interval; during the first time interval, the terminal device does not listen for a wake-up signal. Therefore, when the terminal equipment processes the synchronous signal and monitors the wake-up signal by adopting hardware with different precision, enough time interval between the synchronous signal and the wake-up signal can be ensured, so that the terminal equipment has switching time of the hardware with different precision, and monitors the wake-up signal after switching to the hardware capable of monitoring the wake-up signal, thereby avoiding larger timing deviation when monitoring the wake-up signal. Alternatively, the first time interval may be understood as including two endpoints of the first time interval and a duration, and correspondingly, the first time interval may be understood as excluding time units other than the two endpoints of the first time interval. Or the first time interval may be understood to include both endpoints of the first time interval and units of time other than the first time interval, and correspondingly, the first time interval may be understood to include the duration of the first time interval but not both endpoints of the first time interval.
Referring to fig. 1, fig. 1 is a schematic diagram of a signal transmission system according to an embodiment of the application. The configuration of the apparatus shown in fig. 1 is for example and not intended to limit the embodiments of the present application.

In addition, the AAU can realize partial physical layer processing function, radio frequency processing and related functions of the active antenna. Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, in this network deployment, higher layer signaling (e.g., RRC layer signaling) may be considered to be transmitted by the DU or transmitted by both the DU and the AAU. It is understood that the network device may include at least one of CU, DU, AAU.

The primary radio may be seen as a module for transceiving 5G NR signals/channels in addition to low power wake-up signals.
In the embodiment of the application, the low-power wake-up signal receiver may also be called a low-power-consumption receiver, a wake-up signal receiver (WUS receiver), etc. A low power wake-up signal receiver may be seen as a module that is primarily used to receive signals/channels associated with the low power wake-up signal.
1. Low power wake-up signal (LP-WUS)
The network device may wake the terminal device out of a deep sleep state, such as a power save mode (power saving mode, PSM), by sending a low power wake-up signal. Accordingly, the terminal device determines whether it is necessary to exit the deep sleep state to enter the rrc_idle state, the rrc_inactive state, or the rrc_connected state by listening/detecting a low power wake-up signal. In this way, the terminal device can enter a deep sleep state while being awakened by the network.
For simplicity of description, the low power wake-up signal may also be referred to herein simply as wake-up signal (WUS). That is, the "low power consumption wake-up signal" mentioned in the present application may be collectively referred to as "wake-up signal".
2. Low power consumption wake-up signal receiver
In some scenarios, the terminal device may simply turn on the low power wake-up signal receiver independent of the primary radio. Therefore, the terminal equipment can not only turn off the main radio to achieve the purpose of saving energy (reducing power consumption), but also monitor the low-power consumption wake-up signal through the low-power consumption wake-up signal receiver to wait to be woken up by the network, thereby achieving the purpose of network accessibility. The signal receiver is awakened through the main radio and low power consumption, and the purposes of energy saving and network accessibility are simultaneously achieved. In some scenarios, the low-power wake-up signal receiver may monitor the low-power wake-up signal according to a denser frequency, so that the terminal device is awakened with a lower time delay, and thus the low-power wake-up signal receiver also potentially has the benefit of reducing the time delay.
For simplicity of description, the low power wake-up signal receiver may also be referred to herein simply as a low power receiver (low power receiver, LPR). That is, the "low power consumption wake-up signal receiver" mentioned in the present application may be collectively referred to simply as "low power consumption receiver".
3. Preamble (preamble) and data
The wake-up signal may be divided into two parts: preamble and data. The preamble may include a Delimiter (Delimiter) portion, a Synchronization (SYNC) portion, and a Gap (Gap) portion. The preamble may be used for the low power receiver to learn the wake-up signal to start transmission, for the low power receiver to learn the starting position of the data, or for time/frequency synchronization. The data may also be referred to as wake-up signal data. The data may be used to transport control information and data information of the network.
4. Synchronization signal
The synchronization signal is a signal periodically sent by the network device, and is mainly used for time/frequency synchronization of the low-power consumption receiver.
5. Receiving method of low-power consumption receiver
In the embodiment of the application, the low-power consumption receiver can have the following two receiving methods:
(1) First class receiving method
The first type of receiving method may be that the low power consumption receiver periodically detects a wake-up signal.
In this method, the power consumption of detecting the wake-up signal once is large, but the average power consumption is low due to the long period (the low power consumption receiver only needs to wake up once every long period to detect). Since it is necessary to wake up periodically for detection, a low power receiver requires accurate time synchronization.
In addition, under this method, the low power consumption receiver generates a deviation (erro) in timing (timing) due to frequency drift (frequency drift). When the period is too large, the accumulated timing deviation will be too large; when the timing deviation exceeds a certain degree (such as exceeds a fraction or one modulation symbol), the demodulation decoding performance is drastically reduced, which is represented by a large miss rate (miss detection rate, MDR) and/or false alarm rate (FALSE ALARM RATE, FAR).
(2) Second class receiving method
The second type of receiving method may be that the low power consumption receiver may be in a state of detecting a wake-up signal (also referred to as a stand-by state) all the time.
In this way, the power consumption for detecting the wake-up signal once is low, and the average power consumption is low although the detection is always performed. Low power receivers do not require very accurate time synchronization because of the constant detection.
Under this approach, when the network device does not transmit a wake-up signal for a long time, the accumulated timing offset will also be excessive. When the timing deviation exceeds a certain degree (for example, exceeds a fraction or one modulation symbol), although the low power consumption receiver may assume that a plurality of time points are detected as the starting points of the wake-up signals (demodulation decoding is performed if the wake-up signals are channels, and sequence correlation operation is performed if the wake-up signals are signals), the influence of the timing deviation may be reduced, but if the network device is not synchronized for a long time, the time interval between the transmission of the wake-up signals by the network device and the detection of the wake-up signals by the low power consumption receiver is too large, resulting in too large delay.
Thus, the wake-up signal may also comprise a synchronization signal for low power consumption reception synchronization (at least correcting timing deviations, for envelope detection). The synchronization signal may not employ OOK modulation. The synchronization signal may be transmitted in the form of a frequency domain sequence. Since the frequency domain sequence behaves in the time domain as a filtered time domain sequence receiver may employ a time domain correlation approach (i.e., the received time domain signal is correlated with a time domain version of the local sequence or portion of the sequence). In practice, the time domain correlation approach is equivalent to the frequency domain point multiplication approach (i.e., the received frequency domain signal is point multiplied with a frequency domain version of the local sequence or portion of the sequence).
6. Architecture for low power consumption receiver
In the embodiment of the application, the low-power consumption receiver can have the following three architectures:
The first architecture is an envelope detection (envelop detection) architecture based on zero intermediate frequency (zero IF), which can be done in baseband.
The second architecture is a low IF (low IF) based envelope detection architecture, which can be done at an intermediate frequency.
A third architecture is an envelope detection architecture based on radio frequency, which can be done in radio frequency.
Both of the above three architectures can implement the two types of receiver modes described above.
7. Modulation of wake-up signals (modulation)
In the embodiment of the application, in order to reduce the complexity of the low-power consumption receiver, the wake-up signal can be modulated by on-off keying (OOK).
This is because OOK modulation has only amplitude information, and no frequency or phase information, and the amplitude has only two amplitudes, high and low (or zero). For OOK, the receiving method may be envelope detection (envelope detection) which directly accumulates the amplitude of the received signal, which requires less power consumption due to its simplicity. In this way, the low power consumption receiver in the terminal device can be reduced to detect the energy of the modulation symbol (instead of the amplitude/phase of the modulation symbol), and can be determined to be on (on) as long as the energy of the modulation symbol is detected to exceed a certain threshold, and off (off) otherwise.
In addition, since the processing is performed at radio frequency or intermediate frequency, an envelope detection manner can be adopted.
8. Waveform of wake-up signal
The wake-up signal may be a single tone (single tone) waveform or a single carrier (SINGLE CARRIER) waveform, or a multi-tone (multi tone) waveform or a multi carrier (multi carrier) waveform.
For OOK in a single tone waveform or a single carrier waveform, an OOK modulation symbol may be a single tone or single carrier time domain symbol.
For OOK in a multi-tone or multi-carrier waveform, an OOK modulation symbol may be a multi-tone or multi-carrier time domain symbol, such as an orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) time domain symbol.
For OOK under a multitone or multi-carrier waveform, at a transmitting end (such as a network device), the values of a plurality of subcarriers of one modulation symbol may be random or preset.
In order to map multiple OOK modulation symbols to one OFDM symbol, waveform shaping (shaping) is often required, such as re-mapping OOK modulation symbol sequences into corresponding subcarriers through precoding (e.g., DFT precoding, quasi-inverse based precoding). This has the further advantage that one OFDM symbol has both OOK modulation symbols for low power wake-up signals and modulation symbols for other signal channels.
For OOK under a multitone or multi-carrier waveform, at a receiving end (such as a low-power receiver in a terminal device), one way is envelope detection, which has lower complexity, lower power consumption at the receiving end, but poorer detection performance; another way is sequence detection, in which the OOK sequence is detected by correlating the received sequence with the local sequence, where the detection performance is better, but the complexity is higher, the power consumption at the receiving end is higher, and the number of bits carried in the sequence is generally smaller.
In order to reduce the power consumption of the main radio, in some scenarios or moments, the terminal device may switch off the main radio, simply switch on a low power receiver independent of the main radio to receive a low power wake-up signal from the network device, thereby reducing the transition power consumption of the main radio to wake-up from deep sleep and the power consumption of the detection signal. However, since the low power consumption receiver needs to periodically detect the wake-up signal, once the wake-up signal has a problem of large timing deviation, the wake-up signal is missed. Therefore, how to avoid timing deviation of the wake-up signal in the low power receiver is a urgent problem to be solved.
In the application, if the time interval between the wake-up signal and the synchronous signal is smaller than the offset, the terminal equipment does not monitor the wake-up signal, i.e. the terminal equipment can monitor the wake-up signal in response to the time interval between the wake-up signal and the synchronous signal being larger than or equal to the offset. Accordingly, if the time interval between the wake-up signal and the synchronization signal is smaller than the offset, the network device does not send the wake-up signal. Therefore, when the low-power consumption receiver processes the synchronizing signal and monitors the wake-up signal by adopting hardware with different precision, the terminal equipment can synchronize in time through the synchronizing signal without monitoring the wake-up signal when the time interval is smaller than the offset, so that larger timing deviation is avoided when the terminal equipment monitors the wake-up signal.
In the application, the terminal equipment can determine a first time interval; in the first time interval, the terminal device does not monitor the wake-up signal, i.e. outside the first time interval, the terminal device monitors the wake-up signal. Therefore, when the terminal equipment processes the synchronous signal and monitors the wake-up signal by adopting hardware with different precision, enough time interval between the synchronous signal and the wake-up signal can be ensured, so that the terminal equipment has switching time of the hardware with different precision, and monitors the wake-up signal after switching to the hardware capable of monitoring the wake-up signal, thereby avoiding larger timing deviation when monitoring the wake-up signal.
Referring to fig. 2, fig. 2 is a flowchart of a signal processing method 100 according to an embodiment of the application. The signal processing method 100 is described by taking an example that a time interval between the wake-up signal and the synchronization signal is smaller than an offset, and the terminal device does not monitor the wake-up signal. As shown in fig. 2, the signal processing method 100 may include, but is not limited to, the following steps:
s201, the terminal equipment determines a time interval between a wake-up signal and a synchronous signal;
The network device may send configuration information, such as transmission resources, of the wake-up signal and the synchronization signal, respectively, to the terminal device, and the terminal device may determine a time interval between the wake-up signal and the synchronization signal according to the configuration information. Alternatively, the method may not include step S201.
S202, if the time interval between the wake-up signal and the synchronous signal is smaller than the offset, the terminal equipment does not monitor the wake-up signal.
Correspondingly, if the time interval between the wake-up signal and the synchronization signal is smaller than the offset, the network device does not send the wake-up signal.
Optionally, the method may further include: if the time interval between the wake-up signal and the synchronization signal is greater than or equal to the offset, the terminal device monitors the wake-up signal, i.e. the terminal device monitors the wake-up signal in response to the time interval between the wake-up signal and the synchronization signal being greater than or equal to the offset. Correspondingly, if the time interval between the wake-up signal and the synchronization signal is greater than or equal to the offset, the network device transmits the wake-up signal, i.e. the network device transmits the wake-up signal in response to the time interval between the wake-up signal and the synchronization signal being greater than or equal to the offset.
In an alternative embodiment, the offset is determined, or preset, by any one or more of terminal device capabilities and higher layer parameter configurations. The capability of the terminal device is related to the hardware structure of the terminal device, for example, the time required for switching the hardware structure, such as the time required for switching the terminal device between hardware with different precision (or the time required for switching the low-power consumption receiver between hardware with different precision). For example, the hardware structure of the terminal device includes hardware used when the terminal device processes a synchronization signal, such as an Analog-to-digital converter (Analog-Digitial Convertor, ADC), and hardware used when the terminal device listens for a wake-up signal, such as an ADC. The precision of the hardware adopted by the terminal equipment when processing the synchronous signal is higher than that of the hardware adopted by the terminal equipment when monitoring the wake-up signal, such as an ADC with higher resolution or sampling rate and an ADC with lower resolution or sampling rate. For example, the time required for a hardware configuration switch may be the time required for a terminal device to switch from a higher resolution or sampling rate ADC to a lower resolution or sampling rate ADC. Alternatively, the offset may include terminal device capabilities. Alternatively, the terminal device may report different offsets as different terminal capabilities, for example, a smaller offset corresponds to a fast switching capability and a larger offset corresponds to a slow switching capability.
The higher layer parameter configuration is a time of the higher layer parameter configuration, which is a time of adjusting the radio frequency. The synchronization signal processed by the low power consumption receiver in the terminal device or the terminal device is a signal shared with the main radio, and the synchronization signal may be configured in a shared position in the carrier, so the time for the low power consumption receiver in the terminal device or the terminal device to adjust the radio frequency refers to the time required by the low power consumption receiver in the terminal device or the terminal device to adjust the radio frequency to the shared position, so as to process the synchronization signal. Alternatively, the offset may include the time of the higher layer parameter configuration.
In the embodiment of the application, the terminal equipment can determine the time interval between the wake-up signal and the synchronous signal; if the time interval is smaller than or equal to the offset, the terminal device does not monitor the wake-up signal, and correspondingly, the network device does not send the wake-up signal. Therefore, by adopting the embodiment of the application, the terminal equipment can ensure enough time interval between the wake-up signal and the synchronous signal, so that the terminal equipment has switching time of hardware with different precision, the terminal equipment can monitor the wake-up signal after finishing hardware switching, and larger timing deviation during monitoring the wake-up signal can be avoided.
In another embodiment, the case where the synchronization signal is the one closest to the wake-up signal before the wake-up signal is also explained in comparison with the signal processing method 100. Optionally, in this embodiment, the time interval between the wake-up signal and the synchronization signal includes, but is not limited to, what is described in any one of the following embodiments 1.1 to 1.3.
In embodiment 1.1, the time interval between the wake-up signal and the synchronization signal may be the time interval between the first time of the wake-up signal, which is the first time unit within the duration of the wake-up signal, and the synchronization signal. Wherein the duration is a period of time and the time unit is a time.
In this embodiment, if the time interval between the first time of the wake-up signal and the synchronization signal is smaller than the offset, the terminal device does not monitor the wake-up signal. Accordingly, if the time interval between the first time of the wake-up signal and the synchronization signal is smaller than the offset, the network device does not send the wake-up signal.
Optionally, if the time interval between the first time of the wake-up signal and the synchronization signal is greater than or equal to the offset, the terminal device listens for the wake-up signal, i.e. the terminal device listens for the wake-up signal in response to the time interval between the first time of the wake-up signal and the synchronization signal being greater than or equal to the offset. Correspondingly, if the time interval between the first time of the wake-up signal and the synchronization signal is smaller than the offset, the network device does not transmit the wake-up signal, i.e. the network device transmits the wake-up signal in response to the time interval between the first time of the wake-up signal and the synchronization signal being greater than or equal to the offset.
Optionally, the first time unit is a start time unit of the wake-up signal. Wherein the starting time unit is the starting time. Optionally, the time unit is a symbol, a slot, a subframe, or a frame. For example, the start time unit of the wake-up signal is the 3 rd symbol or the like.
For example, as shown in fig. 3a, taking an example that one slot includes 10 symbols, assuming that the offset is 5 symbols, the starting time unit of the wake-up signal is 7 th symbol, and the time interval between the starting time unit of the wake-up signal and the synchronization signal is 4 symbols, in this case, since the time interval (4 symbols) is smaller than the offset (5 symbols), the terminal device does not monitor the wake-up signal in symbol 3, symbol 4, symbol 5, and symbol 6, and accordingly, the network device does not transmit the wake-up signal in symbol 3, symbol 4, symbol 5, and symbol 6.
Optionally, the first time unit is a preset or configured time unit within the duration of the wake-up signal.
It can be seen that, in this embodiment 1.1, the terminal device may support a time interval in which the first time of the wake-up signal is the reference time of the wake-up signal, so that the terminal device can switch from high-precision hardware to low-precision hardware within the time interval after the synchronization signal is processed, and then monitor the wake-up signal, thereby avoiding a larger timing deviation when monitoring the wake-up signal.
In embodiment 1.2, the time interval between the wake-up signal and the synchronization signal may be a time interval between the wake-up signal and a second time of the synchronization signal, the second time being a second time unit within the duration of the synchronization signal.
It can be seen that if the time interval between the wake-up signal and the second time of the synchronization signal is smaller than the offset, the terminal device does not monitor the wake-up signal. Accordingly, if the time interval between the wake-up signal and the second time of the synchronization signal is smaller than the offset, the network device does not send the wake-up signal.
Optionally, if the time interval between the wake-up signal and the second time of the synchronization signal is greater than or equal to the offset, the terminal device listens for the wake-up signal, i.e. the terminal device listens for the wake-up signal in response to the time interval between the wake-up signal and the second time of the synchronization signal being greater than or equal to the offset. Correspondingly, if the time interval between the wake-up signal and the second time of the synchronization signal is greater than or equal to the offset, the network device transmits the wake-up signal, i.e. the network device transmits the wake-up signal in response to the time interval between the wake-up signal and the second time of the synchronization signal being greater than or equal to the offset.
Optionally, the second time unit is an end time unit of the synchronization signal. Optionally, the time unit is a symbol, a slot, a subframe, or a frame.
For example, as shown in fig. 3b, taking an example that one slot includes 10 symbols, assuming that the offset is 3 symbols, the end time unit of the synchronization signal is the 5 th symbol, and the time interval between the wake-up signal and the end time unit of the synchronization signal is 2 symbols. In this case, since the time interval (2 symbols) is smaller than the offset (3 symbols), the terminal device does not listen to the wake-up signal in symbol 6, symbol 7, and correspondingly, the network device does not transmit the wake-up signal in symbol 6, symbol 7.
Optionally, the second time unit is a preset or configured time unit within the duration of the synchronization signal.
It can be seen that, in this embodiment 1.2, the terminal device may support a time interval in which the second time of the synchronization signal is taken as the reference time of the synchronization signal, so that the terminal device can switch from high-precision hardware to low-precision hardware within the time interval after the synchronization signal is processed, and monitor the wake-up signal, so that a larger timing deviation during monitoring the wake-up signal can be avoided.
In embodiment 1.3, the time interval between the wake-up signal and the synchronization signal may be a time interval between a first time of the wake-up signal and a second time of the synchronization signal, wherein the first time is a third time unit within the duration of the wake-up signal and the second time is a fourth time unit within the duration of the synchronization signal.
In this embodiment, if the time interval between the first time of the wake-up signal and the second time of the synchronization signal is smaller than the offset, the terminal device does not monitor the wake-up signal. Accordingly, if the time interval between the first time of the wake-up signal and the second time of the synchronization signal is smaller than the offset, the network device does not send the wake-up signal.
Optionally, if the time interval between the first time of the wake-up signal and the second time of the synchronization signal is greater than or equal to the offset, the terminal device listens for the wake-up signal, i.e. the terminal device listens for the wake-up signal in response to the time interval between the first time of the wake-up signal and the second time of the synchronization signal being greater than or equal to the offset. Correspondingly, if the time interval between the first time of the wake-up signal and the second time of the synchronization signal is greater than or equal to the offset, the network device transmits the wake-up signal, i.e. the network device transmits the wake-up signal in response to the time interval between the first time of the wake-up signal and the second time of the synchronization signal being greater than or equal to the offset.
Optionally, the third time unit is a start time unit of the wake-up signal; the fourth time unit is an end time unit of the synchronization signal. Optionally, the time unit is a symbol, a slot, a subframe, or a frame. For example, the start time unit of the wake-up signal is the 4 th symbol, and the end time unit of the synchronization signal is the 6 th symbol.
For example, as shown in fig. 3c, taking an example that one slot includes 10 symbols, assuming that the offset is 4 symbols, the start time unit of the wake-up signal is 7th symbol, and the end time unit of the synchronization signal is 3rd symbol, in this case, since the time interval (3 symbols) between the start time unit of the wake-up signal and the end time unit of the synchronization signal is smaller than the offset (4 symbols), the terminal device does not monitor the wake-up signal in symbol 4, symbol 5, and symbol 6, and correspondingly, the network device does not transmit the wake-up signal in symbol 4, symbol 5, and symbol 6.
Optionally, the third time unit is a start time unit of the wake-up signal; the fourth time unit is a start time unit of the synchronization signal.
Optionally, the third time unit is a preset or configured time unit within the duration of the wake-up signal; the fourth time unit is a preset or configured time unit within the duration of the synchronization signal.
It can be seen that, in this embodiment 1.3, the terminal device may support a time interval in which the first time of the wake-up signal is taken as the reference time of the wake-up signal and the second time of the synchronization signal is taken as the reference time of the synchronization signal, so that the terminal device may switch from high-precision hardware to low-precision hardware within the time interval after the synchronization signal is processed, and monitor the wake-up signal, thereby avoiding a larger timing deviation when monitoring the wake-up signal.
In this embodiment, the terminal device may ensure a sufficient time interval between the synchronization signal and the subsequent wake-up signal, so that the terminal device has a switching time of hardware with different precision, that is, the terminal device may switch from high-precision hardware to low-precision hardware in the time interval, and then monitor the wake-up signal, so that a larger timing deviation during monitoring the wake-up signal can be avoided.
In yet another embodiment, the case where the synchronization signal is the nearest one from the time after listening for the wake-up signal is also described in comparison to the signal processing method 100. Alternatively, in this embodiment, the time interval between the wake-up signal and the synchronization signal may include, but is not limited to, what is described in any one of the following embodiments 2.1 to 2.3.
In embodiment 2.1, the time interval between the wake-up signal and the synchronization signal may be a time interval between a first time of the wake-up signal, which is a first time unit within the duration of the wake-up signal, and the synchronization signal. Wherein the duration is a period of time and the time unit is a time.
It can be seen that if the time interval between the first time of the wake-up signal and the synchronization signal is smaller than the offset, the terminal device does not monitor the wake-up signal. Accordingly, if the time interval between the first time of the wake-up signal and the synchronization signal is smaller than the offset, the network device does not send the wake-up signal.
Optionally, if the time interval between the first time of the wake-up signal and the synchronization signal is greater than or equal to the offset, the terminal device listens for the wake-up signal, i.e. the terminal device listens for the wake-up signal in response to the time interval between the first time of the wake-up signal and the synchronization signal being greater than or equal to the offset. Correspondingly, if the time interval between the first time of the wake-up signal and the synchronization signal is greater than or equal to the offset, the network device transmits the wake-up signal, i.e. the network device transmits the wake-up signal in response to the time interval between the first time of the wake-up signal and the synchronization signal being greater than or equal to the offset.
Optionally, the first time unit is an end time unit of the wake-up signal. Optionally, the time unit is a symbol, a slot, a subframe, or a frame.
Optionally, the first time unit is a preset or configured time unit within the duration of the wake-up signal.
It can be seen that, with the embodiment 2.1, the terminal device may support a time interval with the first time of the wake-up signal as the reference time of the wake-up signal, so that the terminal device performs switching of hardware with different precision within the time interval, and thus the terminal device may process the synchronization signal after monitoring the wake-up signal and after completing switching of hardware.
In embodiment 2.2, the time interval between the wake-up signal and the synchronization signal may be a time interval between the wake-up signal and a second time of the synchronization signal, the second time being a second time unit within the duration of the synchronization signal.
It can be seen that if the time interval between the wake-up signal and the second time of the synchronization signal is smaller than the offset, the terminal device does not monitor the wake-up signal. Accordingly, if the time interval between the wake-up signal and the second time of the synchronization signal is smaller than the offset, the network device does not send the wake-up signal.
Optionally, if the time interval between the wake-up signal and the second time of the synchronization signal is greater than or equal to the offset, the terminal device listens for the wake-up signal, i.e. the terminal device listens for the wake-up signal in response to the time interval between the wake-up signal and the second time of the synchronization signal being greater than or equal to the offset. Correspondingly, if the time interval between the wake-up signal and the second time of the synchronization signal is greater than or equal to the offset, the network device transmits the wake-up signal, i.e. the network device transmits the wake-up signal in response to the time interval between the wake-up signal and the second time of the synchronization signal being greater than or equal to the offset.
Optionally, the second time unit is a start time unit of the synchronization signal. Optionally, the time unit is a symbol, a slot, a subframe, or a frame.
Optionally, the second time unit is a preset or configured time unit within the duration of the synchronization signal.
It can be seen that, with the embodiment 2.2, the terminal device may support a time interval in which the second time of the synchronization signal is taken as the reference time of the synchronization signal, so that the terminal device performs switching of hardware with different precision in the time interval, and the terminal device may process the synchronization signal after listening for the wake-up signal and after completing switching of hardware. Accordingly, the network device may send the synchronization signal after the time interval after sending the wake-up signal.
In embodiment 2.3, the time interval between the wake-up signal and the synchronization signal may be a time interval between a first time of the wake-up signal and a second time of the synchronization signal, wherein the first time is a third time unit within the duration of the wake-up signal and the second time is a fourth time unit within the duration of the synchronization signal.
It can be seen that if the time interval between the first time of the wake-up signal and the second time of the synchronization signal is smaller than the offset, the terminal device does not monitor the wake-up signal. Accordingly, if the time interval between the first time of the wake-up signal and the second time of the synchronization signal is smaller than the offset, the network device does not send the wake-up signal.
Optionally, if the time interval between the first time of the wake-up signal and the second time of the synchronization signal is greater than or equal to the offset, the terminal device listens for the wake-up signal, i.e. the terminal device listens for the wake-up signal in response to the time interval between the first time of the wake-up signal and the second time of the synchronization signal being greater than or equal to the offset. Correspondingly, if the time interval between the first time of the wake-up signal and the second time of the synchronization signal is greater than or equal to the offset, the network device transmits the wake-up signal, i.e. the network device transmits the wake-up signal in response to the time interval between the first time of the wake-up signal and the second time of the synchronization signal being greater than or equal to the offset.
Optionally, the third time unit is an end time unit of the wake-up signal, and the fourth time unit is a start time unit of the synchronization signal. Optionally, the time unit is a symbol, a slot, a subframe, or a frame.
Optionally, the third time unit is an end time unit of the wake-up signal, and the fourth time unit is an end time unit of the synchronization signal.
Optionally, the third time unit is a preset or configured time unit within the duration of the wake-up signal, and the fourth time unit is a preset or configured time unit within the duration of the synchronization signal.
It can be seen that, with the embodiment 2.3, the terminal device may support a time interval in which the first time of the wake-up signal is taken as the reference time of the wake-up signal and the second time of the synchronization signal is taken as the reference time of the synchronization signal, so that the terminal device performs switching of hardware with different precision within the time interval, and the terminal device may process the synchronization signal after monitoring the wake-up signal and after completing switching of hardware.
In this embodiment, the terminal device may ensure a sufficient time interval between the wake-up signal and the subsequent synchronization signal, so that the terminal device has a switching time of hardware with different precision, and thus monitors the wake-up signal after completing the hardware switching, and may avoid a larger timing deviation when monitoring the wake-up signal.
Alternatively, the signal processing method 100 described above may be applied in a case where the terminal device listens for the wake-up signal in the first type of receiving method described above. Optionally, if the time interval between the wake-up signal and the synchronization signal is equal to the offset, the terminal device may monitor the wake-up signal based on the period of monitoring the wake-up signal, and correspondingly, the network device may transmit the wake-up signal based on the period of transmitting the wake-up signal.
For example, assuming that the synchronization signal is the closest synchronization signal to the wake-up signal before the wake-up signal, the time interval between the wake-up signal and the synchronization signal is 6 frames, the offset is 6 frames, the end time unit of the synchronization signal is the 7 th frame, and one period of the terminal device for monitoring the wake-up signal is 8 frames, then the terminal device may monitor the wake-up signal at the 8 th frame, that is, the 15 th frame after receiving the synchronization signal, and correspondingly, the network device transmits the monitoring signal at the 15 th frame.
For the first type of receiving method, with the signal processing method 100 provided by the embodiment of the present application, the terminal device may monitor the wake-up signal after the reserved time interval after processing the synchronization signal, and correspondingly, the network device sends the wake-up signal after the reserved time interval after sending the synchronization signal. Therefore, a sufficient time interval can be ensured between the synchronous signal and the wake-up signal, so that the terminal equipment can perform hardware switching with different precision in the time interval, meanwhile, the network equipment can periodically send the synchronous signal or the wake-up signal, and correspondingly, the terminal equipment can periodically receive the synchronous signal or monitor the wake-up signal, thereby avoiding larger timing deviation when the terminal equipment monitors the wake-up signal, and further reducing the omission ratio or the false alarm ratio of the wake-up signal.
Referring to fig. 4, fig. 4 is a flowchart of a signal processing method 200 according to an embodiment of the application. The signal processing method 200 is illustrated by determining a first time interval during which the terminal device does not listen for a wake-up signal. As shown in fig. 4, the signal processing 200 may include, but is not limited to, the following steps:
S401, the terminal equipment determines a first time interval.
Accordingly, the network device determines a first time interval.
In an alternative embodiment, the first time interval may be the time interval between the synchronization signal and the subsequent wake-up signal.
In another alternative embodiment, the first time interval may be the time interval between the synchronization signal and its preceding wake-up signal.
In yet another alternative embodiment, the first time interval may also be the time interval between a preamble and a subsequent wake-up signal.
S402, in a first time interval, the terminal equipment does not monitor a wake-up signal.
Accordingly, the network device does not transmit a wake-up signal during the first time interval.
Optionally, the method further comprises: outside the first time interval, the terminal device listens for a wake-up signal. Correspondingly, outside the first time interval, the network device transmits a wake-up signal.
In the embodiment of the application, the terminal equipment can determine the first time interval, and does not monitor the wake-up signal in the first time interval, so that when the terminal equipment processes the synchronous signal and monitors the wake-up signal by adopting hardware with different precision, enough time interval between the synchronous signal and the wake-up signal can be ensured, so that the terminal equipment has switching time of the hardware with different precision, and monitors the wake-up signal after switching to the hardware capable of monitoring the wake-up signal (such as low-precision hardware), thereby avoiding larger timing deviation when monitoring the wake-up signal.
Referring to fig. 5, fig. 5 is a flowchart of a signal processing method 201 according to an embodiment of the application. In comparison to the signal processing method 200 shown in fig. 4, the signal processing method 201 specifically illustrates a case where the first time interval is a time interval between a synchronization signal and a subsequent wake-up signal. As shown in fig. 5, the signal processing method 201 may include, but is not limited to, the following steps:
S501, the terminal equipment starts with a fifth time unit and ends with the addition of an offset to the fifth time unit, and determines a first time interval, wherein the fifth time unit is within the duration of the synchronous signal.
Correspondingly, the network device starts with a fifth time unit and ends with the fifth time unit plus the offset, and determines a first time interval, wherein the fifth time unit is within the duration of the synchronization signal.
In an alternative embodiment, the specific description of the offset may be referred to in the foregoing step S202, and will not be described herein.
S502, in a first time interval, the terminal equipment does not monitor a wake-up signal.
Accordingly, the network device does not transmit a wake-up signal during the first time interval.
Optionally, the method further comprises: outside the first time interval, the terminal device listens for a wake-up signal. Correspondingly, outside the first time interval, the network device transmits a wake-up signal.
That is, the terminal device does not listen for the wake-up signal within an offset after a fifth time of the synchronization signal, which is a fifth time unit within the duration of the synchronization signal. Accordingly, the network device does not transmit the wake-up signal within the offset after the fifth time of the synchronization signal. Optionally, the terminal device monitors the wake-up signal outside the offset after the fifth time of the synchronization signal, and correspondingly, the network device sends the wake-up signal outside the offset after the fifth time of the synchronization signal. That is, after the synchronization signal is processed, the terminal device needs to keep a time interval and starts to monitor the wake-up signal. Accordingly, after the network device finishes transmitting the synchronization signal, a time interval needs to be reserved and then a wake-up signal needs to be transmitted as required.
Optionally, the fifth time unit is a start time unit or an end time unit of the synchronization signal, or a preset or configured time unit within the duration of the synchronization signal. Optionally, the time unit is a symbol, a slot, a subframe, or a frame. For example, the duration of the synchronization signal is 6 frames, wherein the start time unit of the synchronization signal is the 3 rd symbol and the end time unit is the 5 th and the symbol.
For example, as shown in fig. 6a, taking an example that one slot includes 10 symbols, assuming that the offset after the terminal device determines the start time unit of the synchronization signal is 3 symbols and the start time unit of the synchronization signal is 3 rd symbol, the terminal device does not monitor the wake-up signal in 3 symbols after the 3 rd symbol, that is, in symbol 4, symbol 5, and symbol 6, and correspondingly, the network device does not transmit the wake-up signal before symbol 4, symbol 5, and symbol 6.
For another example, as shown in fig. 6b, taking an example that one slot includes 10 symbols, assuming that the offset after the terminal device determines the end time unit of the synchronization signal is 3 symbols and the end time unit of the synchronization signal is the 5 th symbol, the terminal device does not monitor the wake-up signal in 3 symbols after the 5 th symbol, that is, in symbol 6, symbol 7, and symbol 8, and correspondingly, the network device does not transmit the wake-up signal in symbol 6, symbol 7, and symbol 8.
It can be seen that the terminal device can support a time interval in which the fifth time of the synchronization signal is the reference time of the synchronization signal, so that the terminal device can switch from high-precision hardware to low-precision hardware in the time interval to monitor the wake-up signal, thereby avoiding a larger timing deviation when monitoring the wake-up signal.
In the embodiment of the application, in the offset after the synchronization signal, the terminal equipment does not monitor the wake-up signal, and correspondingly, the network equipment does not send the wake-up signal. Therefore, by adopting the embodiment of the application, enough time interval between the synchronous signal and the subsequent wake-up signal can be ensured, so that the terminal equipment has switching time of hardware with different precision, and the wake-up signal can be immediately monitored after the terminal equipment is switched to the hardware with low precision, thereby avoiding larger timing deviation when the wake-up signal is monitored.
Referring to fig. 7, fig. 7 is a flowchart of a signal processing method 202 according to an embodiment of the application. In comparison with the signal processing method 200 shown in fig. 4, the signal processing method 202 shown in fig. 7 specifically illustrates a case where the first time interval is the time interval between the synchronization signal and the wake-up signal before the synchronization signal. As shown in fig. 7, the signal processing method 202 may include, but is not limited to, the following steps:
And S701, the terminal equipment starts with a sixth time unit and starts with the subtraction of the offset from the sixth time unit, and determines a first time interval, wherein the sixth time unit is within the duration of the synchronous signal.
Correspondingly, the network device determines the first time interval starting with the sixth time unit minus the offset, wherein the sixth time unit is within the duration of the synchronization signal.
In an alternative embodiment, the specific description of the offset may be referred to in the foregoing step S202, and will not be described herein.
S702, in a first time interval, the terminal equipment does not monitor a wake-up signal.
Accordingly, the network device does not transmit a wake-up signal during the first time interval.
Optionally, the method further comprises: outside the first time interval, the terminal device listens for a wake-up signal. Correspondingly, outside the first time interval, the network device transmits a wake-up signal.
That is, the terminal device does not listen for the wake-up signal within an offset before a sixth time of the synchronization signal, which is a sixth time unit within the duration of the synchronization signal. Accordingly, the network device does not transmit a wake-up signal within an offset before the sixth time of the synchronization signal. Optionally, the terminal device listens for the wake-up signal except for an offset before a sixth time of the synchronization signal, where the sixth time of the synchronization signal is a sixth time unit within the duration of the synchronization signal. Correspondingly, the network device sends a wake-up signal outside the offset before the sixth time of the synchronization signal.
That is, the terminal device needs to reserve a time interval as a hardware switching time before the synchronization signal so that the wake-up signal is monitored after switching to the hardware that can monitor the wake-up signal. Correspondingly, the network device needs to reserve a time interval before the synchronization signal as the switching time of hardware with different precision in the terminal device, so that the terminal device can send the wake-up signal to the terminal device as required after switching to the hardware capable of monitoring the wake-up signal.
Optionally, the sixth time unit is a start time unit or an end time unit of the synchronization signal, or a preset or configured time unit within the duration of the synchronization signal.
Optionally, the time unit is a symbol, a slot, a subframe, or a frame.
It can be seen that the terminal device may support a time interval with the sixth time of the synchronization signal as the reference time of the synchronization signal, so that hardware switching with different accuracy is performed within the time interval.
In the embodiment of the application, in the offset before the synchronous signal, the terminal equipment does not monitor the wake-up signal, and correspondingly, the network equipment does not send the wake-up signal. Therefore, by adopting the embodiment of the application, the sufficient time interval before the arrival of the synchronous signal can be ensured, so that the terminal equipment can switch hardware with different precision.
Referring to fig. 8, fig. 8 is a flowchart of a signal processing method 203 according to an embodiment of the application. In comparison with the signal processing method 200 shown in fig. 4, the signal processing method 203 shown in fig. 8 specifically illustrates a case where the first time interval is the time interval between the preamble and the subsequent wake-up signal. As shown in fig. 8, the signal processing method 203 may include, but is not limited to, the following steps:
s801, starting with a seventh time unit, and ending with the addition of an offset to the seventh time unit, the terminal equipment determines a first time interval, wherein the seventh time unit is in the duration of the preamble.
Accordingly, the network device determines the first time interval starting with a seventh time unit and ending with the seventh time unit plus the offset, wherein the seventh time unit is within the duration of the preamble.
The preamble refers to the preamble in the wake-up signal, and the preamble also has a synchronizing effect. Since the wake-up signal is sent on-demand by the network device or is sent discontinuously (discontinuous transmission, DTX), the preamble is also sent on-demand by the network device or is sent discontinuously. Alternatively, the terminal device relies mainly on the synchronization signal for reliable synchronization and by the preamble for opportunistic synchronization. That is, when the network device randomly transmits the synchronization signal, the terminal device may perform time synchronization based on the preamble. The preamble may further improve synchronization accuracy based on the synchronization signal. Alternatively, in some scenarios, the terminal device may receive and process the preamble using high precision hardware.
In an alternative embodiment, the specific description of the offset may be referred to in the foregoing step S202, and will not be described herein.
S802, in a first time interval, the terminal equipment does not monitor a wake-up signal.
Accordingly, the network device does not transmit a wake-up signal during the first time interval.
Optionally, the method further comprises: outside the first time interval, the terminal device listens for a wake-up signal. Correspondingly, outside the first time interval, the network device transmits a wake-up signal.
That is, the terminal device does not listen for the wake-up signal within an offset after a seventh time of the preamble, which is a seventh time unit within the duration of the preamble. Accordingly, the network device does not transmit a wake-up signal within an offset after the seventh time of the preamble. Optionally, the terminal device listens for the wake-up signal outside the offset after the seventh time of the preamble, the seventh time of the preamble being a seventh time unit within the duration of the preamble. Correspondingly, the network device sends a wake-up signal outside the offset after the seventh time of the preamble.
That is, the terminal device needs to keep a time interval (greater than or equal to the offset) after processing the preamble, and then starts to monitor the wake-up signal, and correspondingly, the network device needs to keep a time interval after transmitting the preamble, and then transmits the wake-up signal.
Optionally, the seventh time unit is a start time unit or an end time unit of the preamble, or a preset or configured time unit within the duration of the preamble. Optionally, the time unit is a symbol, a slot, a subframe, or a frame.
It can be seen that the terminal device can support a time interval with the seventh time of the preamble as the reference time of the preamble, so that the terminal device can switch from high-precision hardware to low-precision hardware in the time interval to monitor the wake-up signal, thereby avoiding a larger timing deviation when monitoring the wake-up signal.
It can be seen that, by adopting the embodiment of the present application, in the offset after the preamble, the terminal device does not monitor the wake-up signal, and correspondingly, the network device does not send the wake-up signal. Therefore, a sufficient time interval between the leading signal and the following wake-up signal can be ensured, so that the terminal equipment has switching time of hardware with different precision, and the wake-up signal is monitored after the terminal equipment is switched to the hardware with low precision, thereby avoiding larger timing deviation when the wake-up signal is monitored.
Alternatively, the signal processing method 200, the signal processing method 201, the signal processing method 202, and the signal processing method 203 may be applied to the case that the terminal device listens for the wake-up signal by the second type of receiving method.
For this second type of reception method, although the synchronization signal is periodic, the wake-up signal is not periodic. Therefore, with any one of the signal processing methods 200 to 203 provided in the embodiments of the present application, the terminal device may restart monitoring the wake-up signal after the first time interval, and correspondingly, the network device sends the wake-up signal as needed after the first time interval. In this way, a sufficient time interval can be ensured between the synchronous signal and the wake-up signal before or after the synchronous signal or a sufficient time interval can be ensured between the lead and the wake-up signal after the synchronous signal, so that the terminal equipment performs hardware switching with different precision within the time interval, and meanwhile, the terminal equipment can clearly know when to start monitoring the wake-up signal according to the first time interval, thereby avoiding larger delay when the terminal equipment monitors the wake-up signal.
