[0001] The present application relates to the field of communication technology, and in particular to a communication method, device, chip, chip module and storage medium. Background Art

[0002] In order to save energy in terminal devices, in certain scenarios or at certain times, the terminal device only turns on a low power wakeup signal receiver (LP-WUSreceiver or LP-WUR) that is independent of the main radio. This can not only turn off the main radio as much as possible, but also wake up the main radio by listening to the low power wakeup signal through the low power wakeup signal receiver to achieve network accessibility. The low power wakeup signal receiver is mainly used to receive low power wakeup signals.

[0003] However, there is currently no corresponding solution for further reducing the system overhead of the wake-up signal to further save energy for the terminal device. Summary of the invention

In addition, the character " / ", unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

[0090] In an idle state or an inactive state, monitoring paging, performing radio resource management (RRM) measurements and / or monitoring paging advance indications are the main tasks of the terminal device.

[0091] Monitor paging:

[0092] Generally speaking, in idle or inactive state, the UE needs to monitor the physical downlink control channel (PDCCH) related to paging, also known as type 2-PDCCH. The radio network temporary identity (RNTI) of the paging-related PDCCH is P-RNTI, and the downlink control information (DCI) format used is DCI format 1-0. When the UE detects the paging-related PDCCH (CRC is successfully descrambled using P-RNTI), the UE parses the DCI. The DCI may contain a short message to enable the UE to obtain warning information or update system information. The DCI may also contain scheduling information to enable the UE to receive the physical downlink shared channel (PDSCH) related to paging, obtain the paging message, and further initiate a random access process to enter the connected state. The monitoring occasion of the paging-related PDCCH can be determined by the search space set (SSS) configuration (including the monitoring occasion configuration) and the paging occasion (PO). The monitoring occasion of the paging-related PDCCH can also be called the paging PDCCH monitoring occasion (paging PDCCH monitoring occasion) or the paging monitoring occasion (paging monitoring occasion). Among them, PO is used to determine the starting point of the monitoring occasion in the paging frame (paging frame, PF), and PMO is a plurality of monitoring occasions in sequence starting from the starting point. PMO is one-to-one associated with the synchronization signal block actually sent.

[0093] To perform RRM measurements:

[0094] Generally speaking, in idle or inactive states, the UE needs to perform RRM measurements. RRM measurements include measurements of serving cells and neighboring cells. Measurements of neighboring cells generally include: the base station sets a frequency point, and the UE searches for cells and measures at the frequency point; or the base station sets a frequency point and a physical cell identity (PCI), and the UE uses the PCI to search for cells and measure at the frequency point; or the base station does not set a frequency point or a PCI, and the UE autonomously searches for cells and measures. Neighboring cell measurements can be divided into intra-frequency measurements and inter-frequency measurements. For example, if the synchronization signal block in the measurement object of the neighboring cell is the same as the center frequency and subcarrier spacing of the synchronization signal block of the serving cell, then the measurement is an intra-frequency measurement. For example, if the synchronization signal block in the measurement object of the neighboring cell is different from the center frequency or subcarrier spacing of the synchronization signal block of the serving cell, then the measurement is an inter-frequency measurement. In idle or inactive state, the UE generally needs to perform RRM measurement of the serving cell once in a cycle. When a paging cycle is small, the measurement cycle can be a paging cycle; when a paging cycle is large, the measurement cycle can be a cycle smaller than the paging cycle. The paging cycle is also called the idle state discontinuous reception (I-DRX) cycle.

[0095] Monitor paging advance indication:

[0096] For monitoring paging-related PDCCH and performing RRM measurements, generally speaking, the paging UE wakes up from deep sleep (deepsleep) to process three synchronization signal block bursts (SS / PBCH block burst, SS burst), achieves a certain time-frequency synchronization to monitor the paging-related PDCCH (and receive PDSCH, if the PDCCH is received correctly), and performs RRM measurements at the same time. To this end, the network can configure paging early indication (PEI), and the UE detects the paging early indication before the paging-related PDCCH. If the PEI indicates that the paging-related PDCCH needs to be monitored, the UE continues to monitor the paging-related PDCCH. The paging early indication can also be called the early indication for paging (EIP).

[0097] Generally speaking, PEI comes before PO. When PEI is configured, the UE wakes up from deep sleep to process 1 synchronization signal block burst, and achieves a certain time-frequency synchronization to detect PEI. If PEI indicates that it is necessary to monitor the paging-related PDCCH, the UE continues to process 2 synchronization signal block bursts and continues to monitor the paging-related PDCCH. If PEI indicates that it is not necessary to monitor the paging-related PDCCH, the UE returns to deep sleep. When the group paging rate (group paging probability) is 10%, the probability that the UE needs to monitor the paging-related PDCCH is 10%. Therefore, at a 10% probability, the UE needs to process 3 synchronization signal block bursts, monitor the paging-related PDCCH, and perform RRM measurements; at a 90% probability, the UE only needs to process 1 synchronization signal block burst and perform RRM measurements. In this way, with a 90% probability, the UE processes fewer signals / channels, the wake-up time is shorter (if no signal / channel is processed after waking up from deep sleep, it is in light sleep (light sleep) and the power consumption is smaller. Therefore, by using PEI, the UE can save power.

[0098] The above processes are all receiving processes of the primary radio. Generally speaking, the primary radio is used to process synchronization signal block bursts and monitor PDCCH, and the power consumption of the primary radio is relatively large, including the conversion power consumption (energy) of UE waking up from deep sleep, monitoring paging, performing RRM measurements and / or detecting PEI, etc.

[0099] Low power wake-up signal:

[0100] The network device can wake up the terminal device from a deep sleep state, such as power saving mode (PSM), by sending a low-power wake-up signal.

[0101] Accordingly, the terminal device determines whether it needs to exit the deep sleep state to enter the RRC_IDLE state, RRC_INACTIVE state or RRC_CONNECTED state by monitoring / detecting the low power wake-up signal. In this way, the terminal device can enter the deep sleep state and can be awakened by the network through the low power wake-up signal.

[0102] In order to simplify the description, the "low-power wake-up signal" in this application can be referred to as a "wake-up signal (WUS)". That is to say, the "low-power wake-up signal" mentioned in this application can be referred to as a "wake-up signal".

[0103] Low power wake-up signal receiver:

[0104] 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.

[0105] 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.

[0106] Modulation / waveform of wake-up signal:

[0107] 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.

[0108] 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).

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] Multiple OOK symbols can be mapped to one OFDM symbol. The mapping can be done in the following two ways:

[0114] ◆Sequence direct modulation method

[0115] 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.

[0116] 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.

[0117] ◆Precoding-based method, also known as waveform shaping-based method

[0118] 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.

[0119] 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.

[0120] The preamble part of the wake-up signal:

[0121] 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.

[0122] 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).

[0123] The message part of the wake-up signal:

[0124] 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.

[0125] The message part of the wake-up signal may carry some information, such as a cell identity (cell ID) and / or a UE identity (UE ID). The cell identity information enables the low-power receiver to determine the current cell to reduce inter-cell interference.

[0126] How the wake-up signal carries information:

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] Low power receiver detection timing:

[0133] 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).

[0134] 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.

[0135] Architecture of low power receiver:

[0136] 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.

[0137] Timing deviation and synchronization signals for low power receivers:

[0138] Frequency drift accumulates over a period of time and becomes a timing error, which can be one or more OOK symbols.

[0139] 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).

[0140] 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.

[0141] 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.

[0142] The leading part of the synchronization signal:

[0143] For the reception of synchronization signals, low-power receivers also need to deal with the timing deviation problem first. Generally speaking, a preamble part (or first part) can be placed at the beginning of the synchronization signal. The low-power receiver detects the preamble part by means of a search window. When the preamble part is detected, the starting position of the message part (the part after the preamble part, or the second part) can be determined. The process of determining the starting position of the preamble part can also be regarded as the process of obtaining timing information (correcting timing deviation).

[0144] The message part of the synchronization signal:

[0145] The message part of the synchronization signal may carry some information, such as a cell identity (cell ID). The cell identity information enables the low-power receiver to determine the current cell to reduce inter-cell interference.

[0146] 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.

[0147] How the synchronization signal carries information:

[0148] The synchronization signal can also carry information. The synchronization signal carrying information is equivalent to the message part of the synchronization signal carrying information.

[0149] 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] As mentioned above, the wake-up signal can carry information in two ways, namely, in a channel way and in a signal way.

[0154] Although the channel method carries more information (resulting in lower UE power consumption), the system overhead is relatively large. At this time, generally speaking, the low-power receiver can only use envelope detection to detect the wake-up signal, because if the low-power receiver regards the wake-up signal as a whole (which may include CRC) and uses sequence detection to detect the wake-up signal, it will lead to too many possibilities of sequences and too high detection complexity. The performance of the envelope detection method is poor, so in order to achieve the coverage goal, the system overhead of the wake-up signal is relatively large. In addition, when the channel method is used, CRC needs to be added, which increases the system overhead of the wake-up signal.

[0155] Although the sequence method carries less information (resulting in higher UE power consumption), the system overhead is small. In this case, generally speaking, low-power receivers can use sequence detection to detect the wake-up signal because there are fewer possibilities for the sequence. The sequence detection method has better performance, so under the premise of ensuring coverage of the target, the system overhead of the wake-up signal is not large.

[0156] Therefore, the channel method and the sequence method have their own advantages and disadvantages. The network may choose different methods according to the needs. For example, in the scenario where UE power consumption is more important than system overhead, the network can use the channel method; and in the scenario where system overhead is more important than UE power consumption, the network can use the sequence method. How the network chooses the method of carrying information in different wake-up signals is an urgent problem to be solved.

[0157] In view of this, an embodiment of the present application provides a communication solution, whereby the network device instructs the terminal device that the wake-up signal in the cell carries information in the form of a signal or a sequence, so that the terminal device can accurately know the way in which the wake-up signal selected by the network carries information, thereby improving communication efficiency.

[0158] like Figure 3 FIG. 1 is a flow chart of a communication method provided in an embodiment of the present application. Exemplarily, the method may include the following steps:

[0159] S301. The network device sends first configuration information to the terminal device. Correspondingly, the terminal device receives the first configuration information.

[0160] The first configuration information indicates the type of the wake-up signal, and the type of the wake-up signal includes at least a first type and a second type.

[0161] In this embodiment, the network device notifies that the wake-up signal in the cell uses a channel or sequence to carry information. In this way, the network device can flexibly select which method the wake-up signal uses to carry information according to different scenarios / requirements. The terminal device can determine which method is used to carry information in the wake-up signal in the cell according to the instruction of the network device.

[0162] The types of the wake-up signal include a first type and a second type.

[0163] The first type includes carrying information in the form of coded bits, that is, the wake-up signal carries 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 de-repetition. The method of using coded bits can also be called the method of using channels.

[0164] The first type includes carrying information in the form of a sequence, that is, the wake-up signal carries 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. The sequence method can also be called the signal method.

[0165] The network device may carry the first configuration information in the following implementations, but is not limited to these:

[0166] In one implementation, the first configuration information is carried by system information block 1 (SIB1). The network device sends SIB1 in the primary cell, and the terminal device receives SIB1 when selecting the cell, so that the first configuration information can be parsed. In this case, the reception of the wake-up signal is a relatively important operation, so the first configuration information is relatively important information.

[0167] Another implementation method is that the first configuration information is carried by a system information block (SIBx) other than SIB1. SIBx can be SIB2, SIB3, etc. (due to limited space, they are not listed here). Generally speaking, SIB1 mainly carries non-essential / non-important information of the cell, and SIBx mainly carries non-essential / non-important information of the cell. SIBx can also be called other system information (OSI). The network device can send SIBx as needed, and accordingly, the terminal device can receive SIBx as needed, so that the above-mentioned first configuration information can be parsed. In this case, the reception of the wake-up signal is not a relatively important operation, so the first configuration information is not relatively important information.

[0168] In another implementation, the first configuration information is carried by a paging physical downlink control channel (PDCCH) or a paging message. In this implementation, the first configuration information is dynamically changeable, and the network device can dynamically change the content of the first configuration information as needed. The terminal device receives the first configuration information and can dynamically determine the method used by the wake-up signal in the cell.

[0169] Furthermore, the method may also include the following steps (indicated by dotted lines in the figure):

[0170] S302. The network device sends a wake-up signal to the terminal device according to the first configuration information. Correspondingly, the terminal device receives the wake-up signal according to the first configuration information.

[0171] After the network device sends the first configuration information to the terminal device, the network device can send a wake-up signal to the terminal device according to the first configuration information. That is, the network device can send the wake-up signal to the terminal device according to the manner in which the wake-up signal carries information indicated by the first configuration information. Thus, the terminal device can accurately detect the wake-up signal according to this manner.

[0172] According to a communication method provided in an embodiment of the present application, a network device can enable a terminal device to accurately know the way in which the wake-up signal selected by the network carries information by instructing the terminal device on the type of wake-up signal in the cell, thereby improving communication efficiency.

[0173] When the sequence method is used, since the wake-up signal carries less information, the main radio needs to wake up and receive PEI or PO to obtain more information to determine when random access needs to be initiated. For example, the wake-up signal carries UE group information (which can be carried by the association between the wake-up signal and PEI or PO) or UE subgroup information (which can be carried by the association between the wake-up signal and PEI or PO plus the sequence index), and PEI or PO carries the remaining UE identification information. At this time, the network device needs to send both the wake-up signal and the PEI and / or PO, and the wake-up signal, PEI and PO are likely to be time-division multiplexed. In this way, how to arrange the time domain positions of the wake-up signal, PEI and / or PO to improve system efficiency is an urgent problem to be solved.

[0174] In view of this, an embodiment of the present application provides a communication scheme, in which the network device sends PEI and / or PO after the first time interval after sending the wake-up signal, so as to ensure that the terminal device sends PEI and / or PO only after completing the reception of the wake-up signal, turning on the main radio, and completing a series of operations. This can ensure that the main radio can correctly receive PEI and / or PO, thereby improving the reliability of communication.

[0175] like Figure 4 FIG. 1 is a flow chart of another communication method provided in an embodiment of the present application. Exemplarily, the method may include the following steps:

[0176] S401. The network device sends a wake-up signal to the terminal device. Correspondingly, the terminal device receives the wake-up signal.

[0177] In this embodiment, the network device may send the wake-up signal in a sequence manner, which specifically includes steps of sequence generation, modulation and / or waveform generation, etc. Exemplarily, the wake-up signal may carry part of the UE identification information.

[0178] In order to improve the efficiency of resource utilization, the wake-up signal can reuse the resources of PEIPDCCH or paging PDCCH. For example, the wake-up signal can reuse the frequency domain resources of PEIPDCCH, that is, the control resource set (CORESET), or the wake-up signal can reuse the time domain resources of PEIPDCCH, that is, the listening time configured by the search space set (SSS). At this time, the wake-up signal replaces the function of PEI, and the two do not need to exist at the same time, so the wake-up signal can reuse the resources of PEIPDCCH. For another example, the wake-up signal can reuse the frequency domain resources of paging PDCCH, that is, the control resource set, or the wake-up signal can reuse the time domain resources of paging PDCCH, that is, the listening time configured by the search space set. At this time, the wake-up signal replaces the paging function, and the two do not need to exist at the same time, so the wake-up signal can reuse the resources of paging PDCCH.

[0179] The network device sends a wake-up signal to the terminal device at the PEI timing, PEIPDCCH monitoring timing, PO or paging PDCCH monitoring timing.

[0180] Accordingly, the terminal device monitors the wake-up signal at the PEI timing, PEIPDCCH monitoring timing, PO or paging PDCCH monitoring timing.

[0181] Generally speaking, a PEI opportunity may include one or more PEIPDCCH monitoring opportunities, and a PO may include one or more paging PDCCH monitoring opportunities. After the network device sends a wake-up signal at the above opportunity or monitoring opportunity, it sends PEI and / or paging at the subsequent above opportunity or monitoring opportunity. Correspondingly, after the terminal device detects the wake-up signal at the above opportunity or monitoring opportunity, it monitors PEI and / or paging at the subsequent above opportunity or monitoring opportunity. The "subsequent" here is described in the following steps.

[0182] S402. The network device sends a paging advance indication and / or a paging opportunity to the terminal device after the first time interval. Here, "the network device after the first time interval" means "the network device sends a wake-up signal after the first time interval". Correspondingly, the terminal device receives a paging advance indication and / or a paging opportunity after the first time interval. Here, "the terminal device after the first time interval" means "the terminal device receives a wake-up signal after the first time interval". The above-mentioned "after the first time interval" can be "starting from the end position of the wake-up signal after the first time interval", "starting from the end symbol of the wake-up signal after the first time interval" or "starting from the last symbol of the wake-up signal after the first time interval". The above-mentioned "after the first time interval" can also be "starting from the starting position of the wake-up signal after the first time interval", "starting from the starting symbol of the wake-up signal after the first time interval" or "starting from the first symbol of the wake-up signal after the first time interval". The above-mentioned "after the first time interval" can also be "starting from the preset position of the wake-up signal, after the first time interval", "starting from the preset symbol of the wake-up signal, after the first time interval", "starting from any position of the wake-up signal, after the first time interval" or "starting from any symbol of the wake-up signal, after the first time interval".

[0183] Since the wake-up signal can carry less information when it carries information in a sequence, the network device can also carry the remaining UE identification information through PEI and / or PO.

[0184] In this embodiment, the network device sends a wake-up signal, and sends PEI and / or PO to the terminal device after a preset time interval (e.g., a first time interval). The time domain position of PEI or PO can be determined by the existing network configuration method. It is understandable that "sending PEI" may refer to "sending PEIPDCCH", "sending PEIPDCCH listening opportunity" or "sending PEI opportunity (PEI-O)", etc., and no distinction is made in this application unless otherwise specified. It is understandable that "sending PO" may refer to "sending paging PDCCH", "sending paging PDCCH listening opportunity" or "sending paging", etc., and no distinction is made in this application unless otherwise specified. More generally, "PEI" may refer to "PEIPDCCH", "PEIPDCCH listening opportunity" or "PEI opportunity", etc., and no distinction is made in this application unless otherwise specified. More generally, "PO" may refer to "paging PDCCH", "paging PDCCH listening opportunity" or "paging", etc., and no distinction is made in this application unless otherwise specified. In addition, PEI can refer to the target's PEI, that is, the PEI that the terminal device needs to monitor or the terminal device's own PEI; PO can refer to the target's PO, that is, the PO that the terminal device needs to monitor or the terminal device's own PO; PF can refer to the target's PF, that is, the PF that the terminal device needs to monitor or the terminal device's own PF.

[0185] The network device sends a wake-up signal, and after a first time interval, sends PEI and / or PO. In this way, the network device can wait for the terminal device for a period of time to ensure that the terminal device sends PEI and / or PO only after completing the reception of the wake-up signal, turning on the main radio, and completing a series of operations (such as startup and resynchronization) to ensure that the main radio can correctly receive PEI and / or PO. Since PEI and / or PO are at a preset time position, "sending PEI and / or PO" here can be equivalent to "starting to send PEI and / or PO", "starting to prepare to send PEI and / or PO" or "sending PEI and / or PO at the time position of the most recent PEI and / or PO".

[0186] The terminal device receives the wake-up signal, and receives the PEI and / or PO after the first time interval. In this way, the terminal device can receive the wake-up signal, turn on the main radio, and complete a series of operations (such as startup and resynchronization) within a period of time before receiving the PEI and / or PO to ensure that the main radio can correctly receive the PEI and / or PO. Since the PEI and / or PO are at a preset time position, the "receiving PEI and / or PO" here can be equivalent to "starting to receive PEI and / or PO", "starting to prepare to receive PEI and / or PO" or "receiving PEI and / or PO at the time position of the nearest PEI and / or PO".

[0187] There are several implementation methods for determining the first time interval:

[0188] In one implementation, the first time interval is a preset time interval. In this way, the network device and the terminal device can interoperate at the agreed time interval, saving signaling overhead. The preset time interval may be related to the capability of the terminal device.

[0189] The preset time interval may include the time for the main radio to wake up, ie, the time from a sleep state to an active state.

[0190] The preset time interval may include the time for the main radio to adjust the RF (retuning RF), because the wake-up signal receiver may share a clock (such as an oscillator) with the main radio, and the main receiver needs to re-adjust the RF after waking up to process the synchronization signal / physical broadcast channel block (SS / PBCH block) for subsequent synchronization and / or measurement. The synchronization signal / physical broadcast channel block can be referred to as the synchronization signal block.

[0191] The preset time interval may include the time when the primary radio processes the SS / PBCH block, because the primary radio needs to process one or more SS / PBCH blocks for synchronization and / or measurement.

[0192] Another implementation is that the first time interval is a configured time interval. Exemplarily, the network device sends configuration information to the terminal device, and correspondingly, the terminal device receives the configuration information, wherein the configuration information includes the first time interval. In this way, the network device can configure the first time interval to improve flexibility.

[0193] Another implementation method is that the first time interval is a multiple of the period of the SS / PBCH block. Since the main radio of the terminal device needs more SS / PBCH blocks for synchronization after waking up, and the period of the SS / PBCH block is configurable, the first time interval can be defined as a multiple of the period of the SS / PBCH block. When the period of the SS / PBCH block is small, the first time interval is small; when the period of the SS / PBCH block is large, the first time interval is large.

[0194] Another implementation method is that when the first time point plus the first time interval is less than or equal to the start time point of PO, the start time point of paging PDCCH, the start time point of paging PDCCH monitoring time or the start time point of paging, the network device sends PO in the current DRX cycle, wherein the first time point is the starting position, starting symbol or first symbol of the wake-up signal, and can also be the end position, end symbol or last symbol of the wake-up signal, and can also be a preset position, preset symbol, any position or any symbol in the wake-up signal, and the current DRX cycle is the DRX cycle where the first time point is located. Correspondingly, when the first time point plus the first time interval is less than or equal to the start time point of PO, the start time point of paging PDCCH, the start time point of paging PDCCH monitoring time or the start time point of paging, the terminal device receives PO in the current DRX cycle. In this way, the terminal device can receive PO in the current DRX cycle in a timely manner after detecting the wake-up signal. In another case, when the first time point plus the first time interval is greater than or equal to the start time point of PO, the start time point of paging PDCCH, the start time point of paging PDCCH monitoring opportunity or the start time point of paging, the network device sends PO in the next DRX cycle, wherein the first time point is the starting position, starting symbol or first symbol of the wake-up signal, and may also be the end position, end symbol or last symbol of the wake-up signal, or may be a preset position, preset symbol, any position or any symbol in the wake-up signal, and the next DRX cycle is the first DRX cycle or a certain DRX cycle after the DRX cycle where the first time point is located. Correspondingly, when the first time point plus the first time interval is greater than or equal to the start time point of PO, the start time point of paging PDCCH, the start time point of paging PDCCH monitoring opportunity or the start time point of paging, the terminal device receives PO in the next DRX cycle. In this way, after detecting the wake-up signal, the terminal device may not have time to receive PO in the current DRX cycle, but may receive PO in the next DRX cycle. The above-mentioned start time point of PO may also be a time point related to PO. The above-mentioned starting time point of the paging PDCCH may also be a time point related to the paging PDCCH. The above-mentioned starting time point of the paging PDCCH monitoring opportunity may also be a time point related to the paging PDCCH monitoring opportunity. The above-mentioned starting time point of paging may also be a time point related to paging.

[0195] Another implementation method is that when the first time point plus the first time interval is less than or equal to the start time point of PF, the network device sends PO in the current DRX cycle, wherein the first time point is the starting position, starting symbol or first symbol of the wake-up signal, and may also be the ending position, ending symbol or last symbol of the wake-up signal, or may be a preset position, preset symbol, any position or any symbol in the wake-up signal, and the current DRX cycle is the DRX cycle where the first time point is located. Accordingly, when the first time point plus the first time interval is less than or equal to the start time point of PF, the terminal device receives PO in the current DRX cycle. In this way, the terminal device can receive PO in the current DRX cycle in a timely manner after detecting the wake-up signal. In another situation, when the first time point plus the first time interval is greater than or equal to the start time point of PF, the network device sends PO in the next DRX cycle, wherein the first time point is the starting position, starting symbol or first symbol of the wake-up signal, or may be the ending position, ending symbol or last symbol of the wake-up signal, or may be a preset position, preset symbol, any position or any symbol in the wake-up signal, and the next DRX cycle is the first DRX cycle or a certain DRX cycle after the DRX cycle where the first time point is located. Correspondingly, when the first time point plus the first time interval is greater than or equal to the start time point of PF, the terminal device receives PO in the next DRX cycle. In this way, after detecting the wake-up signal, the terminal device may receive PO in the next DRX cycle if it does not have time to receive PO in the current DRX cycle. The above-mentioned start time point of PF may also be a time point related to PF.

[0196] Another implementation method is that when the first time point plus the first time interval is less than or equal to the start time point of PEI, the start time point of PEI PDCCH, the start time point of PEIPDCCH monitoring opportunity or the start time point of PEI-O, the network device sends PEI in the current DRX cycle, wherein the first time point is the starting position, starting symbol or first symbol of the wake-up signal, and can also be the end position, end symbol or last symbol of the wake-up signal, and can also be a preset position, preset symbol, any position or any symbol in the wake-up signal, and the current DRX cycle is the DRX cycle where the first time point is located. Correspondingly, when the first time point plus the first time interval is less than or equal to the start time point of PEI, the start time point of PEIPDCCH, the start time point of PEIPDCCH monitoring opportunity or the start time point of PEI-O, the terminal device receives PEI in the current DRX cycle. In this way, the terminal device can receive PEI in the current DRX cycle in a timely manner after detecting the wake-up signal. In another case, when the first time point plus the first time interval is greater than or equal to the start time point of PEI, the start time point of PEIPDCCH, the start time point of PEIPDCCH monitoring opportunity or the start time point of PEI-O, the network device sends PEI in the next DRX cycle, wherein the first time point is the starting position, starting symbol or first symbol of the wake-up signal, and can also be the end position, end symbol or last symbol of the wake-up signal, or can be a preset position, preset symbol, any position or any symbol in the wake-up signal. Correspondingly, when the first time point plus the first time interval is greater than or equal to the start time point of PEI, the start time point of PEIPDCCH, the start time point of PEIPDCCH monitoring opportunity or the start time point of PEI-O, the terminal device receives PEI in the next DRX cycle, and the next DRX cycle is the first DRX cycle or a certain DRX cycle after the DRX cycle where the first time point is located. In this way, after detecting the wake-up signal, the terminal device can receive PEI in the next DRX cycle if it does not have time to receive PEI in the current DRX cycle. The above-mentioned starting time point of PEI may also be a time point related to PEI. The above-mentioned starting time point of PEIPDCCH may also be a time point related to PEIPDCCH. The above-mentioned starting time point of PEIPDCCH monitoring timing may also be a time point related to PEIPDCCH monitoring timing. The above-mentioned starting time point of PEI-O may also be a time point related to PEI-O. Another implementation method is that the terminal device may report the preference of the first time interval.For example, the terminal device sends first configuration information to the network device, and correspondingly, the network device receives the first configuration information, wherein the first configuration information includes the first time interval. In this way, the network can know the first time interval preferred by each terminal device, thereby optimizing the configuration of the first time interval.

[0197] According to a communication method provided by an embodiment of the present application, the network device sends PEI and / or PO after the first time interval after sending the wake-up signal, so as to ensure that the terminal device sends PEI and / or PO only after completing the reception of the wake-up signal, turning on the main radio, and completing a series of operations. This can ensure that the main radio can correctly receive PEI and / or PO, thereby improving the efficiency of communication.

[0198] In response to the above-mentioned problem of how to arrange the time domain positions of wake-up signals, PEI and / or PO to improve system efficiency, an embodiment of the present application also provides a communication solution, where the network device can accurately transmit the wake-up signal, PEI and / or PO by agreeing with the terminal device on the timing of transmitting the wake-up signal and transmitting PEI and / or PO, thereby improving the efficiency of communication.

[0199] like Figure 5 FIG. 1 is a flow chart of another communication method provided in an embodiment of the present application. Exemplarily, the method may include the following steps:

[0200] S501. The network device sends a wake-up signal to the terminal device in the nth discontinuous reception cycle. Correspondingly, the terminal device receives the wake-up signal in the nth discontinuous reception cycle.

[0201] S502. The network device sends PEI and / or PO to the terminal device in the n+kth to n+k+mth discontinuous reception (DRX) cycles. Correspondingly, the terminal device receives the paging advance indication and / or paging opportunity in the n+kth to n+k+mth discontinuous reception cycles.

[0202] The network device sends a wake-up signal in the nth discontinuous reception cycle, and sends PEI and / or PO in the n+kth to n+k+mth DRX cycles, where k>=1 or k>=2, n, m>=0, and are all integers. In this way, the network device can wait for the terminal device for a period of time to ensure that the terminal device sends PEI and / or PO only after completing the reception of the wake-up signal, turning on the main radio, and completing a series of operations (such as startup and resynchronization). This period of time is counted in DRX cycles to facilitate the network device and the terminal device to reach an agreement. When k>=1, this period of time is greater than or equal to one DRX cycle. When k>=2, this period of time is greater than or equal to two DRX cycles.

[0203] The terminal device receives the wake-up signal in the nth DRX cycle, and receives PEI and / or PO in the n+kth to n+k+mth DRX cycles, where k>=1 or k>=2, m>=0, and they are all integers. In this way, the terminal device can receive the wake-up signal, turn on the main radio, and complete a series of operations (such as startup and resynchronization) within a period of time before receiving PEI and / or PO to ensure that the main radio can correctly receive PEI and / or PO. This period of time is counted in DRX cycles to facilitate the network device and the terminal device to reach an agreement. When k>=1, this period of time is greater than or equal to one DRX cycle. When k>=2, this period of time is greater than or equal to two DRX cycles.

[0204] According to a communication method provided in an embodiment of the present application, a network device can accurately transmit a wake-up signal, a paging advance indication and / or a paging opportunity by agreeing with a terminal device on the timing of transmitting a wake-up signal and transmitting a paging advance indication and / or a paging opportunity, thereby reducing system overhead and improving communication efficiency.

[0205] In response to the above-mentioned problem of how to arrange the time domain positions of the wake-up signal, PEI and / or PO to improve the system efficiency, an embodiment of the present application also provides a communication solution, in which the network device and the terminal device agree that the starting position of the wake-up signal is equal to the starting position of the PEI or PO, so that the terminal device can accurately receive the wake-up signal, PEI or PO, thereby reducing system overhead and improving communication efficiency.

[0206] like Figure 6 FIG. 1 is a flow chart of another communication method provided in an embodiment of the present application. Exemplarily, the method may include the following steps:

[0207] S601. The network device sends a wake-up signal to the terminal device. Correspondingly, the terminal device receives the wake-up signal.

[0208] S602. The network device sends a paging advance indication and / or a paging occasion to the terminal device. Correspondingly, the terminal device receives the paging advance indication and / or the paging occasion.

[0209] In this embodiment, the network device sends a wake-up signal, wherein the starting position of the wake-up signal is equal to the starting position of the PEI or PO. Since the wake-up signal and the PEI or PO are in different DRX cycles, the starting position of the wake-up signal is equal to the starting position of the PEI or PO, which facilitates the terminal device to accurately receive the wake-up signal, PEI or PO.

[0210] The terminal device receives the wake-up signal, wherein the start position of the wake-up signal is equal to the start position of the PEI or PO. Since the wake-up signal and the PEI or PO are in different DRX cycles, the start position of the wake-up signal is equal to the start position of the PEI or PO, and the wake-up signal, PEI or PO can be accurately received.

[0211] According to a communication method provided in an embodiment of the present application, the network device and the terminal device agree that the starting position of the wake-up signal is equal to the starting position of the PEI or PO, so that the terminal device can accurately receive the wake-up signal, PEI or PO, thereby reducing system overhead and improving communication efficiency.

[0212] Although the low-power receiver can take on some RRM measurement work, or the main receiver can relax the RRM measurement, the main receiver still needs to wake up periodically to perform RRM measurements. After the main receiver wakes up, it can receive PEI and / or PO by the way, so that the low-power receiver does not need to detect the wake-up signal, saving power consumption; accordingly, the network device can also not send a wake-up signal to reduce system overhead. How the terminal device knows that the network device will not send a wake-up signal is an urgent problem to be solved.

[0213] In view of this, an embodiment of the present application provides a communication solution, in which a network device and a terminal device agree not to send / receive a wake-up signal within a first time window, thereby reducing the system overhead of sending a wake-up signal.

[0214] like Figure 7 FIG. 1 is a flow chart of another communication method provided in an embodiment of the present application. Exemplarily, the method may include the following steps:

[0215] S701. The network device determines not to send a wake-up signal within a first time window.

[0216] S702. The terminal device determines that it does not receive a wake-up signal within the first time window.

[0217] In this embodiment, the network device and the terminal device agree that the main radio will wake up to resolve PEI and / or PO after a period of time, so the network device does not send a wake-up signal within a window after the period of time.

[0218] Exemplarily, the network device determines not to send a wake-up signal within a first time window, wherein the first time window is after a first time period. In this way, the network device and the terminal device agree that it is determined not to send a wake-up signal within the first time window, thereby reducing the system overhead of sending the wake-up signal. The terminal device needs to determine that it uses the main radio to monitor PEI and / or PO within the first time window to avoid unnecessary reception of the wake-up signal and waste of power.

[0219] The terminal device determines not to receive the wake-up signal within the first time window, wherein the first time window is after the first time period. In this way, the network device and the terminal device agree that the wake-up signal is not sent within the first time window, thereby reducing the system overhead of sending the wake-up signal. The terminal device needs to determine that the main radio is used to monitor the PEI and / or PO within the first time window to avoid unnecessary reception of the wake-up signal and waste of power.

[0220] Exemplarily, the first time period is X DRX cycles, where X is a positive integer. In this way, counting by DRX cycle can save signaling overhead.

[0221] Exemplarily, the first time window is Y DRX cycles, where Y is a positive integer. In this way, counting by DRX cycle can save signaling overhead.

[0222] According to a communication method provided by an embodiment of the present application, a network device and a terminal device agree not to send / receive a wake-up signal within a first time window, thereby reducing the system overhead of sending the wake-up signal.

[0223] It can be understood that in the above embodiments, the methods and / or steps implemented by the terminal device can also be implemented by components (such as chips or circuits) that can be used for the terminal device; the methods and / or steps implemented by the network device can also be implemented by components (such as chips or circuits) that can be used for the network device.

[0224] The above mainly introduces the scheme provided by the embodiment of the present application from the perspective of interaction between various network elements. Accordingly, the embodiment of the present application also provides a communication device, which is used to implement the above various methods.
