Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method and related devices. Background Art

[0002] In order to reduce the power consumption of the terminal device, in some scenarios or at some times, the terminal device will turn on a wake-up signal receiver independent of the main radio. The wake-up signal receiver can listen to the wake-up signal to wake up the main radio. Therefore, the main radio can be turned off as long as possible and the network can be reachable. The wake-up signal receiver is mainly used to receive the wake-up signal.

[0003] There may be a large timing deviation when the wake-up signal receiver receives the wake-up signal. When the timing deviation exceeds a certain level, the wake-up performance will be reduced. Therefore, how to synchronize the wake-up signal receiver to obtain accurate time synchronization is an urgent problem to be solved. Summary of the invention

[0004] The embodiments of the present application provide a communication method and related devices, which can be synchronized based on a wake-up signal.

[0005] In a first aspect, an embodiment of the present application provides a communication method, which can be executed by a network device or a related device in the network device, the method comprising: configuring a wake-up signal to be sent, wherein the configuration of the wake-up signal comprises a configuration of a leading part.

[0006] It can be seen that in this method, the configuration of the wake-up signal includes the configuration of the leading part, and synchronization can be performed using the leading part, so that the terminal device can also be synchronized based on the wake-up signal.

[0007] In an optional implementation, the configuration of the leading part includes the configuration of multiple sub-parts or sub-sequences of the leading part. It can be seen that in this implementation, the leading part includes multiple sub-parts or sub-sequences, so that the window of the wake-up signal receiver receiving the leading part can always cover one of the sub-parts or sub-sequences, so as to avoid the problem of being unable to synchronize due to the accumulated time deviation being too large after the wake-up signal receiver has not been synchronized for a long time, resulting in the window of the leading part receiving the leading part not being able to cover the complete leading part.

[0008] In an optional implementation, the configuration of the sub-portion or sub-sequence includes the sequence number or index information of the sub-portion or sub-sequence in the leading portion. That is, the configuration of the sub-portion or sub-sequence of the leading portion includes the sequence number information or index information of the sub-portion or sub-sequence in the leading portion. It can be seen that in this implementation, after the terminal device detects a sub-portion or sub-sequence, it can determine the sub-portion or sub-sequence in the leading portion according to the sequence number or index information, thereby facilitating the acquisition of accurate timing information.

[0009] In an optional implementation, the configuration of the wake-up signal includes the configuration of a message part, and a specific field of the message part indicates that the message part includes specific information, wherein the specific information is preset information, and the preset information does not include identification information of the terminal device. It can be seen that this implementation indicates that the message part includes specific information by a specific field, so that it does not include identification information of the terminal device, thereby preventing the terminal device from mistakenly interpreting the message part as identification information of the terminal device and mistakenly waking up the main radio, resulting in unnecessary power consumption.

[0010] In another optional implementation, the configuration of the wake-up signal includes the configuration of the message part, and the message part uses a specific radio network temporary identity (RNTI) to indicate that the message part includes specific information, wherein the specific information does not include the identification information of the terminal device. It can be seen that this implementation uses the specific radio network temporary identity RNTI to inform that the message part does not include the identification information of the terminal device, thereby preventing the terminal device from mistakenly interpreting the message part as the identification information of the terminal device and mistakenly waking up the main radio, resulting in unnecessary power consumption.

[0011] In another optional implementation, the configuration of the wake-up signal includes the configuration of a message part, and the message part adopts a specific length, indicating that the message part includes specific information, wherein the specific information does not include identification information of the terminal device. It can be seen that this implementation uses a specific length to inform that the message part does not include identification information of the terminal device, thereby preventing the terminal device from mistakenly interpreting the message part as identification information of the terminal device and mistakenly waking up the main radio, resulting in unnecessary power consumption.

[0012] In an optional implementation manner, the specific information includes system information. It can be seen that the wake-up signal designed in this implementation manner can not only be used specifically for synchronization, but also can be used to carry some system information.

[0013] In a second aspect, an embodiment of the present application also provides a communication method, which can be performed by a terminal device or related devices therein, such as a chip, etc. The communication method includes: a configuration for receiving a wake-up signal, wherein the configuration of the wake-up signal includes a configuration of a leading part.

[0014] In an optional implementation, the configuration of the leading portion includes the configuration of multiple sub-portions or sub-sequences of the leading portion.

[0015] In an optional implementation, the configuration of the sub-portion or sub-sequence includes the sequence number or index information of the sub-portion or sub-sequence in the leading portion.

[0016] In an optional implementation, the configuration of the wake-up signal includes the configuration of a message part, a specific field of the message part indicates that the message part includes specific information, wherein the specific information is preset information, and the preset information does not include identification information of the terminal device.

[0017] In another optional implementation, the configuration of the wake-up signal includes the configuration of a message part, and the message part uses a specific wireless network temporary identifier RNTI, indicating that the message part includes specific information, wherein the specific information does not include identification information of the terminal device.

[0018] In another optional implementation, the configuration of the wake-up signal includes the configuration of a message part; the message part adopts a specific length, indicating that the message part includes specific information, wherein the specific information does not include identification information of the terminal device.

[0019] In an optional implementation, the specific information includes system information.

[0020] Among them, the beneficial effects of each implementation method in the examples of this application can be found in the relevant contents described in the first aspect and will not be described in detail here.

[0021] In a third aspect, an embodiment of the present application further provides a communication method, which can be executed by a network device or a related device in the network device. The method may include: a configuration of sending a wake-up signal, wherein the configuration of the wake-up signal includes a configuration of a message part.

[0022] It can be seen that the communication method can indicate whether the main radio of the terminal device needs to wake up through the message part.

[0023] In an optional implementation, the message part includes a first sub-part or a first segment. It can be seen that, for a low-complexity wake-up signal receiver, this implementation only requires decoding the first sub-part or the first segment, so that the network can accommodate low-complexity wake-up signals.

[0024] In an optional implementation, the message part includes a first sub-part or a first segment, and the first sub-part or the first segment contains a cyclic redundancy check CRC. This facilitates the terminal device to perform CRC descrambling on the first sub-part or the first segment to determine whether the decoding is successful.

[0025] In another optional implementation, the message part may include a first sub-part or a first segment, and also include a second sub-part or a second segment. In this way, it is beneficial for a high-complexity wake-up signal receiver to decode not only the first sub-part or the first segment, but also the second sub-part or the second segment; and a low-complexity wake-up signal receiver can only decode the first sub-part or the first segment, so that the network can accommodate low-complexity wake-up signal receivers, and can also allow high-complexity wake-up signal receivers to obtain more information, avoiding the high-complexity wake-up signal receiver from waking up with an excessively high probability and wasting power unnecessarily. It can be seen that this implementation can take into account both low-complexity wake-up signal receivers and high-complexity wake-up signal receivers to achieve efficiency and fairness.

[0026] In an optional implementation, the second sub-part or the second segment may also include a cyclic redundancy check CRC, which is helpful for the terminal device to perform CRC descrambling on the second sub-part or the second segment to determine whether the decoding is successful.

[0027] In a fourth aspect, an embodiment of the present application further discloses a communication method, which can be executed by a terminal device or a related device in the terminal device, and the communication method includes: a configuration for receiving a wake-up signal, wherein the configuration of the wake-up signal includes a configuration of a message part.

[0104] In the present application, the network device may be a device used to communicate with the terminal device, which is responsible for the radio resource management (RRM), quality of service (QoS) management, data compression and encryption, data transmission and reception, etc. on the air interface side. Among them, the network device may be a base station (BS) in a communication system or a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, the base transceiverstation (BTS) in the global system for mobile communication (GSM) or code division multiple access (CDMA) communication system, the node B (NB) in the wideband code division multiple access (WCDMA) communication system, the evolutionary node B (eNB or eNodeB) in the LTE communication system, the next generation evolved node B (ng-eNB) in the NR communication system, the next generation node B (gNB) in the NR communication system, the master node (MN) in the dual-link architecture, the second node or secondary node (SN) in the dual-link architecture, etc., without specific limitation.

In addition, the AAU can implement some physical layer processing functions, RF processing, and related functions of active antennas.

The network device includes a network device 102.

[0109] To facilitate understanding of the embodiments of the present application, some concepts involved in the embodiments of the present application are first introduced.

[0110] Low power wake-up signal receiver

[0111] To reduce the power consumption of the main radio's transition from deep sleep to wake up and the power consumption of the detection signal, a low-power receiver independent of the main radio can be used to detect a low-power wake-up signal. The design of the low-power wake-up signal must ensure that the receiver can receive at low power while meeting the sensitivity requirements, or the signal-to-noise ratio requirements at a lower error rate. Compared with a non-low-power wake-up signal, a low-power wake-up signal can enable a low-power wake-up signal receiver to receive the wake-up signal at lower power consumption at the same latency, or to receive the wake-up signal at lower latency at the same power consumption.

[0112] The main radio in the embodiment of the present application may also be referred to as a main transceiver, an overall transceiver, or a regular transceiver, etc. The main radio is mainly used for accessing the network and transmitting and receiving data. The low-power wake-up signal receiver may also be referred to as a low-power receiver, a wake-up signal receiver (WUS receiver), etc.

[0113] Modulation / waveform of wake-up signal

[0114] The following takes on-off keying (OOK) as an example to illustrate the symbol generation of the wake-up signal. It is worth noting that the modulation / waveform of the wake-up signal is not limited to OOK, and there are other modulation / waveforms.

[0115] Generally speaking, in order to simplify the low-power receiver, the wake-up signal adopts OOK modulation. OOK modulation is a type of amplitude shift keying (ASK) modulation, and OOK modulation has only two amplitudes: high (or 1) and low (or 0).

[0116] For OOK, the receiving method can be envelope detection. Envelope detection can demodulate the signal directly by the amplitude of the received signal. Due to its simplicity, the power consumption required is also low. In this way, the low-power receiver in the terminal device can be simplified to detect the energy of the modulation symbol (rather than the amplitude / phase of the modulation symbol). As long as the energy of the modulation symbol is detected to exceed a certain threshold, it can be judged as on, otherwise it is judged as off.

[0117] Since the OOK symbol has only two amplitudes, high (or 1) and low (or 0), the OOK symbol can also be called an OOK bit, an OOK chip or an OOK pulse. In the embodiment of the present application, the OOK symbol is taken as an example for description.

[0118] For OOK in a multi-tone or multi-carrier waveform, an OOK symbol may be a multi-tone or multi-carrier time domain symbol, such as an orthogonal frequency division multiplexing (OFDM) time domain symbol.

[0119] For OOK under multi-tone or multi-carrier waveforms, at the transmitter, an OOK symbol can be mapped to multiple subcarriers. These multiple subcarriers can be combined with subcarriers of other signals / channels to form all subcarriers in an OFDM symbol, so that the low-power wake-up signal can coexist with other signal channels in an OFDM symbol.

[0120] Multiple OOK symbols can be mapped to one OFDM symbol. The mapping can be done in the following two ways:

[0121] Sequential Direct Modulation

[0122] For high (or 1) amplitude OOK symbols, sequence 1 (such as Zidoff-Chu sequence, referred to as ZC sequence) is used to map to the subcarrier subset (OFDM symbol corresponds to a subset of all subcarriers). For low (or 0) amplitude OOK symbols, sequence 0 (such as all-zero sequence) is used to map to the subcarrier subset.

[0123] In this way, in order to have multiple OOK symbols in one OFDM symbol, frequency division multiplexing and time division multiplexing can be used. For frequency division multiplexing, multiple OOK symbols can be mapped to different subcarrier subsets. For time division multiplexing, the subcarrier subset to be mapped can be selected with a higher subcarrier spacing so that multiple OOK symbols can be included in the current OFDM symbol.

[0124] Precoding-based method, also known as waveform shaping-based method

[0125] All OOK symbols corresponding to an OFDM symbol are processed one by one. Each OOK symbol corresponds to a sequence (which can be adopted or repeated). The sequence is mapped to a subset of symbols of the precoded input. After precoding (such as DFT precoding, quasi-inverse-based precoding), waveform shaping (such as frequency domain truncation) is performed, and then the output is mapped to the OFDM subcarrier.

[0126] The number of OOK symbols corresponding to one OFDM symbol is a relatively important parameter. Generally speaking, one OFDM symbol can correspond to M OOK symbols, where M>1 and M can be selected as 8, 4, etc.

[0127] The preamble of the wake-up signal

[0128] For the reception of the wake-up signal, the low-power receiver needs to deal with the timing deviation problem first. Generally speaking, a preamble part (or first part) can be placed at the beginning of the low-power synchronization signal.

[0129] In this way, the low-power receiver detects the leading part by means of a search window. When the leading part is detected, the starting position of the message part (the part after the leading part, or the second part) can be determined. The process of determining the starting position of the leading part can also be regarded as the process of obtaining timing information (correcting timing deviation).

[0130] The message part of the wake-up signal

[0131] The message part of the wake-up signal may refer to a part after the leading part of the wake-up signal, and the message part may be called a data part or a second part.

[0132] The message part of the wake-up signal may carry some information, such as a cell identity (cell identifier or cell ID) and / or a UE identity (UE ID or UE identifier). The cell identity information enables the low-power receiver to determine the current cell to reduce inter-cell interference.

[0133] How wake-up signals carry information

[0134] The wake-up signal may carry information. The wake-up signal carrying information is equivalent to the message part of the wake-up signal carrying information.

[0135] The wake-up signal can carry information in the form of coded bits. The transmitter (such as a network device) includes steps such as repetition, channel coding (such as Manchester coding) and / or adding cyclic redundant check (CRC), and the receiver (such as a terminal device) includes steps such as CRC removal, channel decoding and / or de-repetition. For example, the wake-up signal can use K information bits, encoded as N coded bits, and add M CRC bits. If the low-power receiver decodes K information bits from the received N+M bits and the CRC check succeeds, it can be confirmed that N information bits have been obtained. Using the coded bit method can also be called the channel method.

[0136] When the wake-up signal carries information in the form of coded bits, the low-power receiver can detect the wake-up signal using envelope detection, that is, detecting OOK symbols one by one. At this time, this method has lower performance, lower complexity, and lower receiver power consumption. The low-power receiver can also detect the wake-up signal using sequence detection, that is, correlating the received sequence with all possible local sequences. At this time, due to the large number of sequences, this method has higher performance, higher complexity, and higher receiver power consumption.

[0137] The wake-up signal can also carry information in a sequence. The transmitter (such as a network device) includes steps such as sequence generation, and the receiver (such as a terminal device) includes steps such as sequence detection. For example, the wake-up signal can use 1 sequence, and the low-power receiver detects the presence of this sequence to obtain information, which is generally called 1 bit of information; for another example, the wake-up signal can use 4 sequences, and the low-power receiver detects the presence of these 4 sequences and which one (if any) to obtain information, which is generally called 2 bits of information; for another example, the wake-up signal can use 8 sequences, and the low-power receiver detects the presence of these 8 sequences and which one (if any) to obtain information, which is generally called 3 bits of information. Using a sequence method can also be called a signal method.

[0138] When the wake-up signal carries information in a sequence, the low-power receiver may also detect the wake-up signal in a sequence detection manner. In this case, the receiver consumes less power due to a small number of sequences and low complexity.

[0139] Low power receiver detection timing

[0140] The first type of detection opportunity is when the low-power receiver periodically detects the wake-up signal. At this time, the power consumption of detecting the wake-up signal once is relatively large, but due to the long cycle (the low-power receiver only needs to wake up once every long cycle for detection), the average power consumption is relatively low. Due to the need to wake up periodically for detection, the low-power receiver requires accurate time synchronization. This cycle can be called a duty cycle or a detection cycle (detection cycle or detectionperiodicity).

[0141] The second type of detection opportunity is that the low-power receiver can be in a state of detecting the wake-up signal all the time (also called stand-by state). At this time, the power consumption of detecting the wake-up signal once is low. Although it is always detecting, the average power consumption is also low. Since it is always detecting, the low-power receiver does not need accurate time synchronization.

[0142] Low power receiver architecture

[0143] For OOK modulation, low-power receivers can adopt envelope detection architecture. The envelope detection architecture can include three types. The first is an envelope detection architecture based on zero intermediate frequency (zero IF), in which envelope detection can be completed in the baseband. The second is an envelope detection architecture based on low intermediate frequency (low IF), in which envelope detection can be completed in the intermediate frequency. The third is an envelope detection architecture based on RF, in which envelope detection can be completed in RF. The above three architectures can implement the above two types of reception methods.

[0144] Timing deviation and synchronization signals for low power receivers

[0145] Frequency drift accumulates over a period of time and becomes a timing error, which can be one or more OOK symbols.

[0146] For the first type of detection opportunity (low-power receiver periodically detects the wake-up signal), when the detection period is too long, the accumulated timing deviation will be very large. When the timing deviation exceeds a certain level, the demodulation and decoding performance drops sharply, which is manifested as a large miss detection rate (MDR) and / or false alarm rate (FAR).

[0147] For the second type of detection opportunity (the low-power receiver is always in the state of detecting the wake-up signal), when the base station does not send the wake-up signal for a long time, the accumulated timing deviation will be very large. When the timing deviation exceeds a certain level, the time interval between the base station sending the wake-up signal and the low-power receiver detecting the wake-up signal is too large, resulting in excessive delay.

[0148] Low-power receivers can also be synchronized through a periodic synchronization signal to reduce timing deviation. The synchronization signal can be OOK modulated. The synchronization signal can be sent in the form of a frequency domain sequence (called OFDM modulation or waveform) without OOK modulation. Since the frequency domain sequence is represented as a filtered time domain sequence in the time domain, the receiver can use a time domain correlation method (i.e., the received time domain signal is correlated with the time domain version of the local sequence or part of the sequence). In fact, the time domain correlation method is equivalent to the frequency domain point multiplication method (i.e., the received frequency domain signal is point multiplied with the frequency domain version of the local sequence or part of the sequence). When the synchronization signal is OOK modulated, the synchronization signal can be different from the wake-up signal and be a preset OOK symbol sequence; the synchronization signal can also be the same as the wake-up signal, which is bit-encoded and then modulated into OOK symbols. When the synchronization signal is bit-encoded and then modulated, it can include a preamble part and a message part like the wake-up signal.

[0149] The leading part of the synchronization signal

[0150] For the reception of synchronization signals, low-power receivers also need to deal with the timing deviation problem first. Generally speaking, a leading part (or first part) can be placed at the beginning of the synchronization signal. The low-power receiver detects the leading part by means of a search window. When the leading part is detected, the starting position of the message part (the part after the leading part, or the second part) can be determined. The process of determining the starting position of the leading part can also be regarded as the process of obtaining timing information (correcting timing deviation).

[0151] Message part of the synchronization signal

[0152] The message part of the synchronization signal may carry some information, such as a cell identifier, which enables the low-power receiver to determine the current cell to reduce inter-cell interference.

[0153] Since the message part of the synchronization signal is relatively fixed and the number of possible sequences of the synchronization signal is small, the receiver can still detect the synchronization signal as a sequence. Therefore, no matter the synchronization signal is a preset OOK symbol sequence or encoded bit by bit and then modulated into OOK symbols, the receiver can perform sequence detection.

[0154] How synchronization signals carry information

[0155] The synchronization signal can also carry information. The synchronization signal carrying information is equivalent to the message part of the synchronization signal carrying information.

[0156] The synchronization signal can carry information in the form of coded bits. The transmitter (such as a network device) includes steps such as repetition, channel coding (such as Manchester coding) and / or adding CRC, and the receiver (such as a terminal device) includes steps such as removing CRC, channel decoding and / or removing repetition. For example, the synchronization signal can use K information bits, which are encoded into N coded bits and added with M CRC bits. If the low-power receiver decodes K information bits from the received N+M bits and the CRC check succeeds, it can be confirmed that N information bits have been obtained. Using the coded bit method can also be called the channel method.

[0157] When the synchronization signal carries information in the form of coded bits, the low-power receiver can detect the synchronization signal by envelope detection, that is, detecting OOK symbols one by one. In this case, the performance of this method is lower, the complexity is lower, and the receiver power consumption is lower. The low-power receiver can also detect the wake-up signal by sequence detection, that is, by correlating the received sequence with all possible local sequences. In this case, due to the large number of sequences, the performance of this method is higher, the complexity is higher, and the receiver power consumption is higher.

[0158] The synchronization signal can also carry information in a sequence. The transmitter (such as a network device) includes steps such as sequence generation, and the receiver (such as a terminal device) includes steps such as sequence detection. For example, the synchronization signal can use 1 sequence, and the low-power receiver detects the presence of this sequence to obtain information, which is generally called 1 bit of information; for another example, the synchronization signal can use 4 sequences, and the low-power receiver detects the presence of these 4 sequences and which one (if any) to obtain information, which is generally called 2 bits of information; for another example, the synchronization signal can use 8 sequences, and the low-power receiver detects the presence of these 8 sequences and which one (if any) to obtain information, which is generally called 3 bits of information. Using a sequence method can also be called a signal method.

[0159] When the synchronization signal carries information in a sequence manner, the low-power receiver may also detect the synchronization signal in a sequence detection manner. In this case, the receiver power consumption is low due to the small number of sequences and low complexity.

[0160] As mentioned above, there are two ways for the wake-up signal receiver to receive the wake-up signal. For the first way, that is, the wake-up signal receiver periodically detects the wake-up signal. When the detection period is too long, the accumulated timing deviation will be very large. When the timing deviation exceeds a certain degree, the demodulation and decoding performance drops sharply, which is manifested as a large miss detection rate (MDR) and / or false alarm rate (FAR). For the second way, that is, the wake-up signal receiver is always in the state of detecting the wake-up signal, when the network device does not send the wake-up signal for a long time, the accumulated timing deviation will be very large. When the timing deviation exceeds a certain degree, the time interval between the network device sending the wake-up signal and the wake-up signal receiver detecting the wake-up signal is too large, resulting in excessive delay.

[0161] Therefore, how to synchronize the wake-up signal receiver to obtain accurate time information is an urgent problem to be solved.

[0162] The communication method provided in the embodiments of the present application is described in detail below.

[0163] See also Figure 2 , Figure 2 is a flow chart of a communication method provided in an embodiment of the present application, and the communication method is described in terms of interaction between a terminal device and a network device, such as Figure 2 As shown, the communication method includes but is not limited to the following steps:

[0164] S101. The network device sends a configuration of a wake-up signal, wherein the configuration of the wake-up signal includes a configuration of a leading part; correspondingly, the terminal device receives a configuration of the wake-up signal.

[0165] Optionally, a preamble is placed at the beginning of the wake-up signal. The preamble can also be called the first part. The terminal device can use the preamble for synchronization. Optionally, such as Figure 3 As shown, the message part is placed after the leading part of the wake-up signal. The terminal device can use the message part to obtain the information sent by the network. The message part can also be called the data part, the load part or the second part. That is to say, the wake-up signal is divided into two parts: the first part (leading part) and the second part (message, data or load part). The wake-up signal can also have only one part, namely the second part (message, data or load part). When the wake-up signal has only one part, the second part of the wake-up signal can refer to the wake-up signal. In this application, "the second part of the wake-up signal", "the second part", "the message part of the wake-up signal", "the message part", "the data part of the wake-up signal", "the data part", "the load part of the wake-up signal" and "the load part" can all be replaced with "wake-up signal".

[0166] Optionally, after receiving the configuration of the wake-up signal, the terminal device can detect the preamble part in a search window manner. When the preamble part is detected, the starting position after the preamble part can be determined. Therefore, the process of detecting the preamble part can also be regarded as a process of obtaining timing information (correcting timing deviation), thereby processing the timing deviation problem in the process of receiving the wake-up signal. Among them, the search window can also be called a preamble monitoring window, which is a window for receiving the preamble.

[0167] In the present application, the terminal device can blindly detect the leading part in the search window through the wake-up signal receiver therein. The terms "wake-up signal receiver" or "low-power receiver" or terminal device in the present application can be interchangeable when describing. For example, the terminal device can be regarded as a wake-up signal receiver or a low-power receiver of the terminal device, etc. This application does not make a distinction to accommodate descriptions that may appear in future protocols. Optionally, a high-complexity wake-up signal receiver can be synchronized through the primary synchronization signal (PSS) and the secondary synchronization signal (SSS) in the synchronization signal block. For a low-complexity wake-up signal receiver, the wake-up signal of the present application can be used for synchronization. Optionally, a high-complexity wake-up signal receiver can also be synchronized using the wake-up signal described in the present application. In some scenarios, in order to "accommodate" or be compatible with low-complexity wake-up signal receivers, the network needs to broadcast the wake-up signal described in this application for synchronization, regardless of whether there are high-complexity wake-up signal receivers in the cell. At this time, the high-complexity wake-up signal receiver can still use the wake-up signal described in this application to improve synchronization accuracy and / or reduce complexity.

[0168] The communication method described in this application is further explained below in combination with various optional implementations.

[0169] In an optional implementation, the configuration of the leading part includes the configuration of multiple sub-parts or sub-sequences of the leading part. Here, the multiple sub-parts or sub-sequences of the leading part can be repeated so that the window receiving the leading part can always cover one of the sub-parts or sub-sequences. On the other hand, the leading part can have one or more sub-parts or sub-sequences that are sent periodically, and the purpose is to be used for synchronization. In order to reduce system resource overhead, the sub-parts or sub-sequences sent periodically use a long period.

[0170] It can be seen that in this embodiment, the preamble part includes multiple sub-parts or sub-sequences, so that the window for receiving the preamble part of the wake-up signal receiver can always cover one of the sub-parts or sub-sequences, so as to avoid the problem of being unable to synchronize due to the accumulated time deviation being too large after the wake-up signal receiver has not been synchronized for a long time, resulting in the window for receiving the preamble part not being able to cover the complete preamble part. Figure 4 As shown, the accumulated time deviation is too large, and the preamble listening window cannot cover the complete preamble part, which may cause synchronization failure. In this implementation, the preamble part includes multiple sub-parts or sub-sequences (the preamble itself is a sequence), and the window for receiving the preamble of the low-complexity wake-up signal receiver can always cover one of the sub-parts to avoid "the low-complexity low-power receiver has been out of synchronization for a long time, and the accumulated time deviation is extremely large, resulting in its receiving preamble window not covering the complete preamble part." For example, Figure 5 As shown, it is assumed that the number X of sub-preambles included in the preamble part is equal to 3, such as Figure 5 , which are Sub-preamble 1, Sub-preamble 2, and Sub-preamble 3. In this way, the terminal device can synchronize by successfully monitoring a sub-preamble using the preamble monitoring window.

[0171] In an optional implementation, the configuration of the sub-portion or sub-sequence includes the serial number (numbering) or index (index) information of the sub-portion or sub-sequence in the leading portion. It can be seen that in this implementation, after the terminal device detects a sub-portion or sub-sequence, it can determine the number of the sub-portion or sub-sequence in the leading portion according to the serial number or index information, thereby facilitating the acquisition of accurate timing information.

[0172] In an optional embodiment, the sequence number or index information of the sub-portion or sub-sequence in the leading portion includes the starting position of the sub-portion or sub-sequence in the sequence. In other words, the sub-portion or sub-sequence is a part of the complete sequence, and different sub-portions or sub-sequences (with different sequence numbers or indexes) have different starting positions in the sequence. In this way, different sub-portions or sub-sequences can be defined by different starting positions by only pre-defining the complete sequence.

[0173] See also Figure 6 , Figure 6 is a flow chart of a communication method provided in an embodiment of the present application, and the communication method is described in terms of interaction between a terminal device and a network device, such as Figure 6 As shown, the communication method includes but is not limited to the following steps:

[0174] S201. The network device sends a message part of a wake-up signal; correspondingly, the terminal device receives the message part of the wake-up signal. The configuration of the wake-up signal may include the configuration of the message part.

[0175] The network device may indicate the configuration of the message part of the wake-up signal and send the message part of the wake-up signal at an appropriate time; correspondingly, the terminal device may receive the configuration of the message part of the wake-up signal and receive the message part of the wake-up signal at an appropriate time. The message part of the wake-up signal may carry some information, such as a cell identifier and a terminal equipment identity (TE ID). The terminal equipment identity may be a user equipment identity, for example, Figure 7 As shown, the message part may include UE ID. Among them, the cell identification information enables the wake-up signal receiver to determine the current cell to reduce interference between cells. It can be understood that the "identification information of the terminal device" can be directly the terminal device identification, or it can be a part of the terminal device identification, or it can be the grouping (UE group) information of the terminal device or the subgroup (UE subgroup) information of the terminal device. The "identification information of the terminal device" can be any identification information related to the terminal device. Unless otherwise specified, this application does not make any special limitation.

[0176] In the embodiment of the present application, the wake-up signal can be a wake-up signal specifically used for synchronization, which can be called a beacon. Therefore, the message part of the wake-up signal cannot carry information for waking up the terminal device. So, how should the message part of the wake-up signal be designed to avoid the terminal device from mistakenly interpreting the message part as identification information of the terminal device and mistakenly waking up the main radio, resulting in unnecessary power consumption. The embodiment of the present application provides several optional implementation methods including but not limited to the following, so that the terminal device can interpret the wake-up signal as a wake-up signal specifically used for synchronization:

[0177] In an optional implementation, a specific field of the message part indicates that the message part includes specific information, wherein the specific information is preset information, and the preset information does not include identification information of the terminal device. That is, when the specific field of the message part is a preset value (such as 1 or 0), the message part includes specific information.

[0178] For example, Figure 8As shown, the message part includes specific information but does not include the UE ID, so that the terminal device knows that the wake-up signal is a wake-up signal specifically used for synchronization. It can be seen that this embodiment indicates that the message part includes specific information through a specific field, that is, the wake-up signal does not include the identification information of the terminal device, thereby preventing the terminal device from mistakenly interpreting the message part as the identification information of the terminal device and mistakenly waking up the main radio, resulting in unnecessary power consumption.

[0179] In another optional implementation, the CRC of the message part uses a specific radio network temporary identifier RNTI, indicating that the message part includes specific information, wherein the specific information does not include identification information of the terminal device. That is, when the RNTI of the CRC of the message part is a specific RNTI, the message part includes specific information.

[0180] For example, Fig. 9 As shown, the CRC of the message part is scrambled with a specific RNTI to obtain a specific CRC. In this way, when the terminal device successfully descrambles the CRC in the message part with the specific RNTI, it is determined that the specific information does not contain the terminal device identification information. It can be seen that this implementation method notifies that the message part does not contain the identification information of the terminal device by means of a specific wireless network temporary identification RNTI, thereby preventing the terminal device from mistakenly interpreting the message part as the identification information of the terminal device and mistakenly waking up the main radio, resulting in unnecessary power consumption.

[0181] In another optional implementation, the message part adopts a specific length, indicating that the message part includes specific information, wherein the specific information does not include identification information of the terminal device. That is, when the length of the message part is a specific length, the message part includes specific information.

[0182] For example, the terminal device uses a specific length (such as Fig.10 As shown, when the specific information is decoded by the specific payload size and the CRC is successfully descrambled, it is determined that the specific information does not contain the terminal device identification information. It can be seen that this implementation method notifies that the message part does not contain the terminal device identification information by means of a specific length, thereby preventing the terminal device from mistakenly interpreting the message part as the terminal device identification information and mistakenly waking up the main radio, resulting in unnecessary power consumption.

[0183] In another optional implementation, the message part adopts a specific sequence, indicating that the message part includes specific information, wherein the specific information does not include identification information of the terminal device. That is, when the message part is a specific sequence, the message part includes specific information. It can be understood that in addition to using the form of coded bits to carry information, the message part can also use the form of a sequence to carry information. When the message part uses the form of a sequence to carry information, the terminal device can determine whether the message part is sent and / or the information carried by the message part by means of sequence detection.

[0184] For example, the terminal device uses a specific sequence to decode the message part and determines that the specific information does not contain the terminal device identification information. It can be seen that this implementation uses a specific sequence to inform that the message part does not contain the terminal device identification information, thereby avoiding the terminal device from mistakenly interpreting the message part as the terminal device identification information and mistakenly waking up the main radio, resulting in unnecessary power consumption.

[0185] Optionally, in the above-mentioned several optional implementations of enabling the terminal device to interpret that the wake-up signal is a wake-up signal specifically used for synchronization, the specific information may also include system information. In this way, the wake-up signal specifically used for synchronization may be used to carry some system information.

[0186] The wake-up signal can also contain only the message part. In this case, there is no need to configure the message part specifically, such as Figures 7 to 10 As shown, the wake-up signal can replace the message part, including the content included in the message part described in the above embodiment, and the corresponding explanation is given below. That is to say, in another embodiment, the network device sends a wake-up signal; accordingly, the terminal device receives the wake-up signal. The network device can indicate the configuration of the wake-up signal and send the wake-up signal at an appropriate time; accordingly, the terminal device can receive the configuration of the wake-up signal and receive the wake-up signal at an appropriate time.

[0187] In an optional implementation, a specific domain of the wake-up signal indicates that the wake-up signal includes specific information, wherein the specific information is preset information, and the preset information does not include identification information of the terminal device. That is, when the specific domain of the wake-up signal is a preset value (such as 1 or 0), the wake-up signal includes specific information. It can be seen that this implementation uses a specific domain to indicate that the wake-up signal includes specific information, that is, the wake-up signal does not include identification information of the terminal device, thereby avoiding the terminal device from mistakenly interpreting the wake-up signal as identification information of the terminal device, and mistakenly waking up the main radio, resulting in unnecessary power consumption.

[0188] In another optional implementation, the CRC of the wake-up signal adopts a specific wireless network temporary identifier RNTI, indicating that the wake-up signal includes specific information, wherein the specific information does not include the identification information of the terminal device. In other words, when the RNTI of the CRC of the wake-up signal is a specific RNTI, the wake-up signal includes specific information. It can be seen that this implementation uses a specific wireless network temporary identifier RNTI to inform that the wake-up signal does not include the identification information of the terminal device, thereby avoiding the terminal device from mistakenly interpreting the wake-up signal as the identification information of the terminal device, and mistakenly waking up the main radio, resulting in unnecessary power consumption.

[0189] In another optional implementation, the wake-up signal adopts a specific length, indicating that the wake-up signal includes specific information, wherein the specific information does not include the identification information of the terminal device. That is, when the length of the wake-up signal is a specific length, the wake-up signal includes specific information. It can be seen that this implementation uses a specific length to inform that the wake-up signal does not include the identification information of the terminal device, thereby avoiding the terminal device from mistakenly interpreting the wake-up signal as the identification information of the terminal device, and mistakenly waking up the main radio, resulting in unnecessary power consumption.

[0190] In another optional implementation, the wake-up signal uses a specific sequence, indicating that the wake-up signal includes specific information, wherein the specific information does not include the identification information of the terminal device. That is to say, when the wake-up signal is a specific sequence, the wake-up signal includes specific information. It can be understood that in addition to using the form of coded bits to carry information, the wake-up signal can also carry information in the form of a sequence. When the wake-up signal carries information in the form of a sequence, the terminal device can determine whether the wake-up signal is sent and / or the information carried by the wake-up signal by means of sequence detection. It can be seen that this implementation uses a specific sequence to inform that the wake-up signal does not contain the identification information of the terminal device, thereby avoiding the terminal device from mistakenly interpreting the wake-up signal as the identification information of the terminal device, and mistakenly waking up the main radio, resulting in unnecessary power consumption.

[0191] In an optional implementation manner, the specific information includes system information. It can be seen that the wake-up signal designed in this implementation manner can not only be used specifically for synchronization, but also can be used to carry some system information.

[0192] It is understandable that the above wake-up signal is not necessarily periodic or always sent. In other words, the network device can send the wake-up signal as needed, and the terminal device confirms whether the wake-up signal is sent through "blind detection". This can reduce the system (resource) overhead of the wake-up signal.

[0193] Optionally, the wake-up signal receiver can also be synchronized by a periodic and / or continuously transmitted synchronization signal to stably reduce the timing deviation, although the system (resource) overhead of the synchronization signal is relatively large at this time. The synchronization signal can be OOK modulated, or the synchronization signal can be sent in the form of a frequency domain sequence (called OFDM modulation or waveform) without OOK modulation. Since the frequency domain sequence is represented as a filtered time domain sequence in the time domain, the wake-up signal receiver can use a time domain correlation method (i.e., the received time domain signal is correlated with the time domain version of the local sequence or part of the sequence). In fact, the time domain correlation method is equivalent to the frequency domain point multiplication method (i.e., the received frequency domain signal is point multiplied with the frequency domain version of the local sequence or part of the sequence). When the synchronization signal is OOK modulated, the synchronization signal can be different from the wake-up signal and be a preset OOK symbol sequence; the synchronization signal can also be the same as the wake-up signal, which is bit-encoded and then modulated into OOK symbols. When the synchronization signal is bit-encoded and then modulated, it can include a preamble part and a message part like the wake-up signal.

[0194] The leading part of the synchronization signal, for the reception of the synchronization signal, the wake-up signal receiver also needs to deal with the timing deviation problem first. Generally speaking, a leading part (or the first part) can be placed at the beginning of the synchronization signal. The wake-up signal receiver detects the leading part by a search window. When the leading part is detected, the starting position of the message part (the part after the leading part, or the second part) can be determined. The process of determining the starting position of the leading part can also be regarded as the process of obtaining timing information (correcting timing deviation).

[0195] The message part of the synchronization signal can carry some information, such as the cell identification. The cell identification information enables the wake-up signal receiver to determine the current cell to reduce inter-cell interference. Since the message part of the synchronization signal is relatively fixed and the number of possible sequences of the synchronization signal is small, the wake-up signal receiver can still detect the synchronization signal as a sequence. Therefore, whether the synchronization signal is a preset OOK symbol sequence or is encoded bit by bit and then modulated into OOK symbols, the wake-up signal receiver can perform sequence detection.

[0196] In another embodiment, the network device sends a configuration of a wake-up signal, wherein the configuration of the wake-up signal includes a configuration of a message portion; accordingly, the terminal device receives the configuration of the wake-up signal, and the communication method of the information indicating whether the main radio of the terminal device needs to wake up through the message portion may include but is not limited to the following implementations:

[0197] In an optional implementation, the message part includes a first sub-part or a first segment. It can be seen that, for a low-complexity wake-up signal receiver, this implementation only requires decoding the first sub-part or the first segment, so that the network can accommodate low-complexity wake-up signals.

[0198] In an optional implementation, the message part includes a first sub-part or a first segment, and the first sub-part or the first segment contains a cyclic redundancy check CRC. This facilitates the terminal device to perform CRC descrambling on the first sub-part or the first segment to determine whether the decoding is successful.

[0199] In an embodiment of the present application, a low-complexity wake-up signal receiver can only process "one-way" wake-up signal (such as a low-power wake-up signal with an OOK waveform), while a high-complexity wake-up signal receiver can process "multi-way" wake-up signals (such as a low-power wake-up signal with an OOK waveform). Here, "multi-way" wake-up signal refers to frequency division multiplexing of multiple wake-up signals (such as frequency division multiplexing of two low-power wake-up signals with OOK waveforms). For example, a high-complexity wake-up signal receiver can adopt a parallel multi-way envelope detection architecture. When low-complexity wake-up signal receivers and high-complexity wake-up signal receivers coexist in the network, how the network takes into account both and achieves efficiency and fairness is an urgent problem to be solved.

[0200] Therefore, the embodiment of the present application also provides an implementation method, and the message part may include a first sub-part or a first segment, and also include a second sub-part or a second segment. In this way, it is beneficial to make the high-complexity wake-up signal receiver not only need to decode the first sub-part or the first segment, but also need to decode the second sub-part or the second segment; the low-complexity wake-up signal receiver can only decode the first sub-part or the first segment, so that the network can accommodate the low-complexity wake-up signal receiver, and can also make the high-complexity wake-up signal receiver obtain more information, avoiding the high-complexity wake-up signal receiver waking up with too high a probability, and unnecessary power consumption. It can be seen that this implementation method can take into account both the low-complexity wake-up signal receiver and the high-complexity wake-up signal receiver. When the low-complexity wake-up signal receiver and the high-complexity wake-up signal receiver coexist in the network, the network takes both into account to achieve efficiency and fairness. The first sub-part and the second sub-part can be frequency-division multiplexed or time-division multiplexed; the first segment and the second segment can be frequency-division multiplexed or time-division multiplexed.

[0201] In an optional implementation, the second sub-part or the second segment may also include a cyclic redundancy check CRC, which is helpful for the terminal device to perform CRC descrambling on the second sub-part or the second segment to determine whether the decoding is successful.

[0202] For example, Fig.11As shown, the message part can be based on time division multiplexing, and according to the frequency increase, it includes a second segment and a first segment, and the first segment and the second segment have their own CRC, such as CRC1 and CRC2 respectively. The terminal device can determine whether to decode one segment or two segments based on its own capabilities.

[0203] As described above, the message part can be divided into two sub-parts, which can also be called splits. The sub-parts can be independently decoded and / or CRC-checked. The low-complexity wake-up signal receiver only receives the first part, and the high-complexity wake-up signal receiver receives the first part and the second part. Therefore, when the low-complexity wake-up signal receiver and the high-complexity wake-up signal receiver coexist in the network, the network takes both into account to achieve efficiency and fairness.

[0204] The wake-up signal may also include only the message part, in which case there is no need to specially configure the message part.

[0205] In an optional implementation, the wake-up signal includes a first sub-part or a first segment. It can be seen that, for a low-complexity wake-up signal receiver, this implementation only requires decoding the first sub-part or the first segment, so that the network can accommodate the low-complexity wake-up signal.

[0206] In an optional embodiment, the wake-up signal includes a first sub-part or a first segment, and the first sub-part or the first segment contains a cyclic redundancy check CRC. This facilitates the terminal device to perform CRC descrambling on the first sub-part or the first segment to determine whether the decoding is successful.

[0207] In an embodiment of the present application, a low-complexity wake-up signal receiver can only process "one-way" wake-up signal (such as a low-power wake-up signal with an OOK waveform), while a high-complexity wake-up signal receiver can process "multi-way" wake-up signals (such as a low-power wake-up signal with an OOK waveform). Here, "multi-way" wake-up signal refers to frequency division multiplexing of multiple wake-up signals (such as frequency division multiplexing of two low-power wake-up signals with OOK waveforms). For example, a high-complexity wake-up signal receiver can adopt a parallel multi-way envelope detection architecture. When low-complexity wake-up signal receivers and high-complexity wake-up signal receivers coexist in the network, how the network takes into account both and achieves efficiency and fairness is an urgent problem to be solved.

[0208] Therefore, the embodiment of the present application also provides an implementation method, and the wake-up signal may include a first sub-part or a first segment, and also include a second sub-part or a second segment. In this way, it is beneficial to make the high-complexity wake-up signal receiver not only need to decode the first sub-part or the first segment, but also need to decode the second sub-part or the second segment; so that the low-complexity wake-up signal receiver can only decode the first sub-part or the first segment, so that the network can accommodate the low-complexity wake-up signal receiver, and can also make the high-complexity wake-up signal receiver obtain more information, avoiding the high-complexity wake-up signal receiver waking up with too high a probability, and unnecessary power consumption. It can be seen that this implementation method can take into account both the low-complexity wake-up signal receiver and the high-complexity wake-up signal receiver. When the low-complexity wake-up signal receiver and the high-complexity wake-up signal receiver coexist in the network, the network takes both into account to achieve efficiency and fairness. The first sub-part and the second sub-part can be frequency-division multiplexed or time-division multiplexed; the first segment and the second segment can be frequency-division multiplexed or time-division multiplexed.

[0209] In an optional implementation, the second sub-part or the second segment may also include a cyclic redundancy check CRC, which is helpful for the terminal device to perform CRC descrambling on the second sub-part or the second segment to determine whether the decoding is successful.

[0210] For example, Fig.11 As shown, the wake-up signal can be based on time division multiplexing, and according to the frequency increase, it includes a second segment and a first segment, and the first segment and the second segment have their own CRCs, such as CRC1 and CRC2, respectively. The terminal device can determine whether to decode one segment or two segments based on its own capabilities.

[0211] As described above, the wake-up signal can be divided into two sub-parts, which can also be called splits. The sub-parts can be independently decoded and / or CRC-checked. A low-complexity wake-up signal receiver only receives the first part, and a high-complexity wake-up signal receiver receives the first part and the second part. This allows the network to take both into account when a low-complexity wake-up signal receiver and a high-complexity wake-up signal receiver coexist in the network, achieving efficiency and fairness.
