[0019] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0020] Unless the context requires otherwise, throughout the specification and claims, the terms "comprise / include" and other forms thereof, such as the third person singular form "comprises / includes" and the present participle form "comprising / including", are to be interpreted as open and inclusive, that is, as meaning "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example" or "some examples" are intended to indicate that a particular feature, structure, material or characteristic associated with the embodiment or example is included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the particular features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0021] The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified with "first," "second," etc., may explicitly or implicitly include one or more of such features. Throughout this disclosure, unless otherwise specified, "plurality" means two or more.

[0022] In the embodiments of the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present disclosure should not be interpreted as being more preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0023] Additionally, the use of “based on” is meant to be open and inclusive, as a process, step, calculation, or other action “based on” one or more stated conditions or values ​​may, in practice, be based on additional conditions or values ​​beyond those stated.

[0024] The network can send paging messages to terminals (User Equipment, UE) in both idle and connected states. The paging process can be triggered by the core network to notify a UE of a paging request, or by the base station to notify a system information update. Paging messages are scheduled using the Physical Downlink Control Channel (PDCCH) scrambled by the Radio Network Temporary Identifier (RNTI) and transmitted on the Physical Downlink Shared Channel (PDSCH). The terminal detects the corresponding PDCCH at the paging occasion (PO) to determine whether the PDSCH indicated by the PDCCH carries the paging message. If the terminal does not detect the corresponding PDCCH at a PO, it means that there is no paging message at that PO. At this time, the terminal enters a sleep state and does not receive data until the next PO. This mode is called discontinuous reception (DRX). In other words, the terminal needs to perform blind detection of the PDCCH at each PO, resulting in high terminal power consumption.

[0025] In order to reduce the power consumption of the terminal, the related technology introduces a wake-up signal (Wake Up Signal, WUS), that is, the base station sends a signal before each PO to indicate whether to perform PDCCH detection. The terminal first detects the WUS and determines whether to detect the corresponding PDCCH based on the detection result of the WUS. For example, when a WUS is detected, the terminal detects the PDCCH corresponding to the WUS, otherwise, the terminal does not detect the PDCCH. The introduction of the WUS reduces the number of times the terminal detects the PDCCH, thereby saving the power consumption of the terminal. In order to further reduce the power consumption of the terminal, a low-power wake-up signal (LP-WUS) is proposed. The terminal uses a specific receiver / receiving module to receive the low-power wake-up signal, and uses the low-power wake-up signal to wake up the receiver for data transmission and data reception. When the terminal does not detect the low-power wake-up signal, the receiver is in a deep sleep state, which can further reduce the power consumption of the terminal. However, the related technology does not provide an implementation method for how to send a low-power wake-up signal.

[0026] Based on this, the embodiments of the present disclosure provide a signal sending method, a signal receiving method, an apparatus and a storage medium, which configures sending parameters and then sends a wake-up signal based on the sending parameters, that is, provides a method for sending a wake-up signal, thereby reducing the power consumption of the terminal.

[0027] The following describes the solutions of the embodiments of the present disclosure in conjunction with the accompanying drawings.

[0028] The technical solutions provided by the embodiments of the present disclosure can be applied to various mobile communication networks, for example, new radio (NR) mobile communication networks using fifth-generation mobile communication technology (5G), future mobile communication networks, or multiple communication convergence systems, etc., but the embodiments of the present disclosure are not limited to this.

[0029] Figure 1 is a schematic diagram of the structure of a communication system according to an embodiment of the present disclosure. As shown in Figure 1, the communication system includes but is not limited to a terminal 110 and a base station 120. The terminal 110 and the base station 120 can transmit and receive wireless signals and perform related interactions.

[0030] In a wireless communication scenario, the terminal 110 communicates with the base station 120 through a wireless channel.

[0031] The terminal 110 may be a device with wireless transceiver capabilities, such as a mobile phone, a tablet computer, a wearable device, an in-vehicle device, an augmented reality (AR) / virtual reality (VR) device, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), etc. The embodiments of the present disclosure do not limit the type of terminal.

[0032] Base station 120 can be any of an evolved nodeB (eNB), a next-generation nodeB (gNB), a transmission and reception point (TRP), a transmission point (TP), or some other access node. Based on the size of the service coverage area provided, base stations can be further categorized as macro base stations for providing macro cells, micro base stations for providing micro cells (Pico cells), and femto base stations for providing femto cells. As wireless communication technology continues to evolve, future base stations may also adopt other names.

[0033] It should be understood that Figure 1 is an exemplary structural diagram, and the number of devices included in the communication system shown in Figure 1 is not limited, for example, the number of base stations and terminals is not limited. Furthermore, in addition to the devices shown in Figure 1, the communication system shown in Figure 1 may also include other devices, which is not limited.

[0034] Next, as shown in FIG2 , an embodiment of the present disclosure provides a signal sending method, which is applied to a base station. The base station may be the base station 120 shown in FIG1 . The method includes the following S101 and S102 .

[0035] In S101, transmission parameters are configured.

[0036] In some embodiments, when the base station needs to wake up the terminal to perform PDCCH detection, the base station configures the sending parameters.

[0037] In some embodiments, the transmission parameters include at least one of the following: information type, time domain position, frequency domain position, coding configuration, frequency hopping configuration, interleaving configuration, mapping configuration, first indication, maximum payload, number of repetitions, waveform generation method, beam configuration, and antenna configuration. The first indication is used to indicate whether a cyclic redundancy check (CRC) is added to the wake-up signal, and the information type is used to indicate the information carried by the wake-up signal.

[0038] In some embodiments, the information carried by the wake-up signal includes at least one of the following: earthquake and tsunami warning system (ETWS), commercial mobile alert service (CMAS), system message change indication, full wake-up indication, stop wake-up signal detection indication, group wake-up indication, wake-up indication of at least one terminal to be paged, tracking reference signal (TRS) transmission indication, and cell index.

[0039] In some embodiments, the time domain position is used to indicate the time domain period and / or time domain offset corresponding to the wake-up signal. The time domain period is expressed in units of one of the following: monitoring window, time slot, second, or millisecond. The monitoring window is the duration during which the wake-up signal can be sent. It should be understood that the time domain period corresponding to the wake-up signal refers to the time domain period within which the wake-up signal is sent, and the time domain offset corresponding to the wake-up signal refers to the time offset after the start of the period / fixed start at which the wake-up signal is sent.

[0040] In some embodiments, the frequency domain position is used to indicate the subcarrier and / or frequency domain offset corresponding to the wake-up signal. It should be understood that the subcarrier corresponding to the wake-up signal refers to the subcarrier at which the wake-up signal starts or ends, and the frequency domain offset corresponding to the wake-up signal refers to the offset between the starting subcarrier, the ending subcarrier, and the fixed subcarrier before the wake-up signal is sent.

[0041] In some embodiments, the coding configuration is used to indicate a coding mode and / or code rate corresponding to the wake-up signal. The coding mode includes at least one of the following: Reed-Muller code (RM), Polar code, repetition coding, Manchester coding, and low-density parity check code (LDPC). The configured code rate is 1 / Z, where Z is a positive integer greater than or equal to 1.

[0042] In some embodiments, the frequency hopping configuration is used to indicate a second indication and / or a frequency hopping mode corresponding to the wake-up signal. The second indication is used to indicate whether the frequency hopping corresponding to the wake-up signal is enabled, that is, to indicate whether the corresponding frequency hopping is enabled when the wake-up signal is sent. If frequency hopping is enabled, the frequency hopping mode can be pre-set. The frequency hopping mode includes a frequency hopping granularity and a frequency hopping position, the frequency hopping granularity is K1 symbols, K1 is a positive integer greater than or equal to 1, the frequency hopping position is K2 frequency domain positions, and K2 is a positive integer greater than or equal to 2. For example, K2 is equal to 2, that is, the frequency hopping position is 2 frequency domain positions, and for another example, K2 is equal to 4, that is, the frequency hopping position is 4 frequency domain positions, etc.

[0043] As an example, when the encoding method corresponding to the wake-up signal is configured as Manchester encoding with a code rate less than 1 / 2, the frequency hopping enable corresponding to the wake-up signal is configured. In other words, when the encoding method corresponding to the wake-up signal is configured as Manchester encoding with a code rate less than 1 / 2, the frequency hopping enable corresponding to the wake-up signal is configured. It should be understood that based on the above configuration, the wake-up signal can obtain frequency hopping gain during transmission.

[0044] As an example, if the encoding method corresponding to the wake-up signal is configured as 1 / 4 Manchester coding and two information bits are carried per time domain symbol during transmission, the value of K1 is configured to be 1, that is, the frequency hopping granularity is 1 time domain symbol. It should be understood that only based on the above configuration can the wake-up signal obtain frequency hopping gain during transmission.

[0045] As another example, when the preset conditions are met, K1 is configured to be 2 multiplied by the information load to be sent and then divided by the number of information bits carried on a time domain symbol when sending. That is, when the preset conditions are met, K1 is configured to be 2*information load to be sent / number of information bits carried on a time domain symbol when sending.

[0046] The preset condition is any one of the following: the encoding method corresponding to the wake-up signal is Manchester encoding with a code rate of 1 / 2 and repetition encoding; the encoding method corresponding to the wake-up signal is Manchester encoding with a code rate of 1 / 2 and the number of repetitions is greater than 1. It should be understood that only when the preset conditions are met and K1 is configured as described above can the wake-up signal obtain frequency hopping gain during transmission.

[0047] In some embodiments, the interleaving configuration is used to indicate a third indication and / or interleaving mode corresponding to the wake-up signal, that is, to indicate the third indication and / or interleaving mode corresponding to the sending of the wake-up signal. The third indication is used to indicate whether interleaving corresponding to the wake-up signal is enabled, and the interleaving mode is a predefined mode. Exemplarily, the base station inputs the encoded data into a predefined matrix in a row-first, column-second order, and then outputs it in a column-first, row-second order, or vice versa. This is not further described here.

[0048] In some embodiments, the maximum load is used to indicate the maximum load corresponding to sending the wake-up signal, that is, to indicate the maximum value of the load corresponding to sending the wake-up signal.

[0049] In some embodiments, the mapping configuration is used to indicate a mapping mode corresponding to the wake-up signal, that is, to indicate a mapping mode corresponding to sending the wake-up signal, and the mapping mode includes at least one of the following: discontinuous frequency domain mapping and continuous frequency domain mapping.

[0050] In some embodiments, the number of repetitions is used to indicate the corresponding number of repetitions when sending the wake-up signal.

[0051] In some embodiments, the waveform generation method includes at least one of the following: amplitude shift keying (ASK), binary on-off keying (OOK), frequency shift keying (FSK), and orthogonal frequency division multiplexing (OFDM).

[0052] In some embodiments, the beam configuration is used to indicate the corresponding beam direction when sending the wake-up signal, and the beam direction may include one or more.

[0053] In some embodiments, the antenna configuration is used to indicate the corresponding multi-antenna transmission mode when sending the wake-up signal, and the multi-antenna transmission mode includes one of the following: open-loop precoding, closed-loop precoding, transmission diversity, and antenna selection; that is, one of the following is used when sending the wake-up signal: open-loop precoding, closed-loop precoding, transmission diversity, and antenna selection.

[0054] As an example, configuring the sending parameters may be configuring the sending parameters based on the first set.

The first transmission parameter corresponding to each transmission format is preset and / or fixed, and G is a positive integer greater than or equal to 1. The first transmission parameter is a subset of the transmission parameters.

[0091] In S102 , a wake-up signal is sent based on the sending parameters.

[0092] The wake-up signal is used to wake up the terminal so that the terminal can perform PDCCH detection.

[0093] In some embodiments, the wake-up signal may be a low-power wake-up signal.

[0094] Based on the embodiment shown in Figure 2, the base station configures the sending parameters, and when the coding mode corresponding to the wake-up signal is configured as Manchester coding with a code rate less than 1 / 2, the frequency hopping enable corresponding to the wake-up signal is configured, or, when the coding mode corresponding to the wake-up signal is configured as Manchester coding with a code rate of 1 / 4 and the information bits carried on one symbol when sending are 2, the value of K1 is configured to be 1, or, when the preset conditions are met, K1 is configured to be 2 multiplied by the information load to be sent and then divided by the information bits carried on one symbol when sending, so that a frequency hopping gain is obtained when the wake-up signal is transmitted, and then the wake-up signal is sent based on the sending parameters. A method for sending a wake-up signal suitable for a separate receiver / receiving module is provided, so that the terminal can perform PDCCH detection at an appropriate time, thereby reducing the power consumption of the terminal.

[0095] In some embodiments, as shown in FIG3 , an embodiment of the present disclosure provides a signal receiving method, which is applied to a terminal, which may be the terminal 110 shown in FIG1 . The method includes the following S201 and S202 .

[0096] In S201, transmission parameters are acquired.

[0097] The transmission parameters may be predefined or configured by the base station. In other words, obtaining the transmission parameters may be obtaining predefined transmission parameters or receiving transmission parameters configured by the base station.

[0098] In some embodiments, obtaining the transmission parameters includes at least one of the following: obtaining transmission parameters corresponding to one or more pieces of information in an information set consisting of information carried by the wake-up signal; obtaining transmission parameters corresponding to one or more resources in a resource set consisting of resource locations corresponding to when the wake-up signal is sent; obtaining transmission parameters corresponding to one or more loads in a payload set consisting of payload sizes corresponding to the wake-up signal; and obtaining transmission parameters corresponding to one or more formats in a format set consisting of formats corresponding to when the wake-up signal is sent. For the corresponding descriptions of the information set, resource set, payload set, and format set, reference can be made to the relevant descriptions in S101 above and are not repeated here.

[0099] In S202 , a wake-up signal is received based on the sending parameters.

[0100] The wake-up signal may be a low-power wake-up signal. The transmission parameters include at least one of the following: information type, time domain position, frequency domain position, coding configuration, frequency hopping configuration, interleaving configuration, mapping configuration, first indication, maximum payload, number of repetitions, waveform generation mode, beam configuration, and antenna configuration. The first indication indicates whether a CRC is added to the wake-up signal; the information type indicates the information carried by the wake-up signal. For a description of the contents of the transmission parameters, refer to the corresponding description in S102 above and are not further elaborated here.

[0101] Based on the embodiment shown in FIG3 , in the embodiment of the present disclosure, the terminal receives a wake-up signal based on a transmission parameter, so that the terminal can perform PDCCH detection at an appropriate time, thereby reducing the power consumption of the terminal.

[0102] The following describes a signal sending method and a signal receiving method provided by an embodiment of the present disclosure with reference to several examples.

[0103] As an example, taking the first set as an information set consisting of information carried by the wake-up signal, and the information set being the above-mentioned information set 1 as an example, the following examples A1 to A14 may be included.

[0104] Example A1

[0105] As can be seen from the above description of information set 1, information set 1 includes first information and second information. Assume that the base station configures the transmission parameters for the first information as follows: time domain position for each monitoring window, encoding method for RM with a code rate of 1 / 4, and waveform generation method for OOK; the base station configures the transmission parameters corresponding to the second information as follows: time domain position for every second monitoring window, a first indication for indicating the addition of an 8-bit CRC, and waveform generation method for OOK.

[0106] Assume that a system message change indication needs to be sent.

[0107] The base station sets the system message change indication to position 1. Assuming that the first information is 4 bits, the first information is in the order of earthquake and tsunami warning indication and commercial mobile alert service, system message change indication, full wake-up indication, and stop wake-up signal detection indication to determine the position of each information. It can be seen that the system message change indication is the second in the first information. The corresponding position is set to 1, that is, the first information is 0100, and RM encoding with a code rate of 1 / 4 is performed and then sent using OOK. Because the first information can be sent in each monitoring window, the base station can choose the nearest monitoring window to send it.

[0108] The terminal determines that the first information must be monitored in each monitoring window based on the sending parameters, and the second information needs to be monitored every two monitoring windows. The first information uses RM encoding with a code rate of 1 / 4, and the second information uses CRC. Therefore, the terminal monitors LP-WUS according to the sending parameters. When the first information is monitored, the terminal receives the system message.

[0109] Example A2

[0110] Assume that the base station configures the sending parameters corresponding to the first information as: the time domain position is each monitoring window, the encoding method is RM with a code rate of 1 / 4, and the waveform generation method is OOK; configure the sending parameters corresponding to the second information as: the time domain position is every 2 monitoring windows, the first indication is used to indicate the addition of an 8-bit CRC, and the waveform generation method is OOK.

[0111] Assume that a system message change indication needs to be sent.

[0112] The base station determines that the first information is 1. This is because, assuming that the first information is 1 bit, as long as any of the earthquake and tsunami warning indication, commercial mobile alert service, system message change indication, full wake-up indication, and stop wake-up signal detection indication needs to be sent, the first information is set to 1, and RM encoding with a code rate of 1 / 4 is performed before sending. Because the first information can be sent in each monitoring window, the base station selects the nearest monitoring window for sending.

[0113] The terminal determines that the first information must be monitored in each monitoring window based on the sending parameters, and the second information needs to be monitored every two monitoring windows. The first information uses RM with a code rate of 1 / 4, and the second information uses CRC. Therefore, the terminal monitors LP-WUS according to the sending parameters. When the first information is detected to be 1, the terminal receives the data.

[0114] Example A3

[0115] Assume that the base station configures the sending parameters corresponding to the first information as: the time domain position is each monitoring window, the coding method is RM and Manchester code, and the code rate is 1 / 2 RM and 1 / 2 Manchester code respectively, and the waveform generation method is OOK; configure the sending parameters corresponding to the second information as: the time domain position is every 2 monitoring windows, the first indication is used to indicate the addition of an 8-bit CRC, and the waveform generation method is OOK.

[0116] Assume that a system message change indication needs to be sent.

[0117] The base station determines that the first information is 1. Assuming the first information is 1 bit, if any of the following needs to be sent: Earthquake and Tsunami Warning Indication, Commercial Mobile Alert Service, System Message Change Indication, Full Wake-up Indication, or Stop Wake-up Signal Detection Indication, the first information is set to 1, and then RM encoding with a code rate of 1 / 2 is performed, followed by Manchester encoding with a code rate of 1 / 2, before transmission. Because the first information can be transmitted in any monitoring window, the base station selects the most recent monitoring window for transmission.

[0118] The terminal determines that the first information must be monitored in each monitoring window based on the sending parameters, and the second information needs to be monitored every two monitoring windows. The first information uses RM with a code rate of 1 / 2 and Manchester code with a code rate of 1 / 2, and the second information uses CRC. Therefore, the terminal monitors LP-WUS according to the sending parameters. When the first information is detected to be 1, the terminal receives the data.

[0119] Example A4

[0120] Assume that the base station configures the sending parameters corresponding to the first information as: the time domain position is each monitoring window, the coding method is RM and Manchester code, and the code rate is 1 / 2 RM and 1 / 2 Manchester code respectively, the first indication is used to indicate the addition of 8-bit CRC, and the waveform generation method is OOK; the sending parameters corresponding to the second information are configured as: the time domain position is every 2 monitoring windows, the first indication is used to indicate the addition of 8-bit CRC, and the waveform generation method is OOK.

[0121] Assume that a system message change indication needs to be sent.

[0122] The base station determines that the first information is 1, because it is assumed that the first information is 1 bit. As long as any one of the earthquake and tsunami warning indication, commercial mobile alert service, system message change indication, full wake-up indication, and stop wake-up signal detection indication needs to be sent, the first information is set to 1, and after adding an 8-bit CRC, RM encoding with a code rate of 1 / 2 is performed, and then Manchester encoding with a code rate of 1 / 2 is performed and sent. Because the first information can be sent in each monitoring window, the base station selects the nearest monitoring window to send.

[0123] The terminal determines that the first information must be monitored in each monitoring window based on the sending parameters, and the second information needs to be monitored every two monitoring windows. The first information uses an 8-bit CRC, and the encoding method includes RM with a code rate of 1 / 2 and Manchester code with a code rate of 1 / 2. The second information uses CRC, so the terminal monitors LP-WUS according to the sending parameters. When the first information is detected to be 1, the terminal receives the data.

[0124] Example A5

[0125] Assume that the base station configures the sending parameters corresponding to the first information as follows: the time domain position is each monitoring window, the coding method is RM and Manchester code, and the code rate is 1 / 2 RM and 1 / 2 Manchester code respectively, the first indication is used to indicate the addition of an 8-bit CRC, the third indication is used to indicate the interleaving enable corresponding to the wake-up signal, and the waveform generation method is OOK; the sending parameters corresponding to the second information are configured as follows: the time domain position is every 2 monitoring windows, the first indication is used to indicate the addition of an 8-bit CRC, and the waveform generation method is OOK.

[0126] Assume that a system message change indication needs to be sent.

[0127] The base station determines that the first information is 1, assuming that the first information is 1 bit. As long as any of the earthquake and tsunami warning indication, commercial mobile alert service, system message change indication, full wake-up indication, and stop wake-up signal detection indication needs to be sent, the first information is set to 1, an 8-bit CRC is added, and RM encoding with a code rate of 1 / 2 is performed. Manchester encoding with a code rate of 1 / 2 is then performed, and then interleaving is performed. After interleaving, it is sent. One interleaving process is to input the encoded information into a matrix with row priority and then output it with column priority. The matrix size can be pre-set. Because the first information can be sent in each monitoring window, the base station selects the nearest monitoring window for transmission.

[0128] The terminal determines that the first information must be monitored in each monitoring window according to the sending parameters, and the second information needs to be monitored every 2 monitoring windows. The first information uses 8-bit CRC, and the code rate is 1 / 2 RM and 1 / 2 Manchester code. The second information uses CRC and interleaving is enabled. Therefore, the terminal monitors LP-WUS according to the sending parameters. When the first information is detected to be 1, the terminal receives the data.

[0129] Example A6

[0130] Assume that the base station configures the sending parameters corresponding to the first information as follows: the time domain position is each monitoring window, the coding method is RM and Manchester code, and the code rate is 1 / 2 RM and 1 / 2 Manchester code respectively, the first indication is used to indicate the addition of an 8-bit CRC, the third indication is used to indicate the interleaving enable corresponding to the wake-up signal, the waveform generation method is OOK, the second indication is used to indicate the frequency hopping enable corresponding to the wake-up signal and the frequency hopping granularity is 1 symbol, and the frequency hopping position is the preset 4 frequency domain positions; the sending parameters corresponding to the second information are configured as follows: the time domain position is every 2 monitoring windows, the first indication is used to indicate the addition of an 8-bit CRC, and the waveform generation method is OOK.

[0131] Assume that a system message change indication needs to be sent.

[0132] The base station determines that the first information is 1, because it is assumed that the first information is 1 bit. As long as any one of the earthquake and tsunami warning indication, commercial mobile alert service, system message change indication, full wake-up indication, and stop wake-up signal detection indication needs to be sent, the first information is set to 1, and after adding an 8-bit CRC, RM encoding with a code rate of 1 / 2 is performed, and then Manchester encoding with a code rate of 1 / 2 is performed and interleaved. After interleaving, it is sent and mapped to the preset 4 frequency domain positions based on 1 symbol sequence when sending. Because the first information can be sent in each monitoring window, the base station selects the nearest monitoring window to send.

[0133] The terminal determines that the first information must be monitored in each monitoring window based on the sending parameters, and the second information needs to be monitored every two monitoring windows. The first information uses an 8-bit CRC, and the code rate is 1 / 2 RM and 1 / 2 Manchester code. The second information uses CRC, interleaving is enabled, and frequency hopping is enabled. Therefore, the terminal monitors LP-WUS according to the sending parameters. When the first information is detected to be 1, the terminal receives the data.

[0134] Example A7

[0135] Assume that the base station configures the sending parameters corresponding to the first information as: the time domain position is each monitoring window, the encoding method is RM with a code rate of 1 / 4, and the waveform generation method is OOK; configure the sending parameters corresponding to the second information as: the time domain position is every 2 monitoring windows, the first indication is used to indicate the addition of an 8-bit CRC, the maximum load is 8 bits, and the waveform generation method is OOK.

[0136] Assume that the terminal with group index 3 needs to be woken up.

[0137] The base station determines to send the second information. Assuming that the group index is in a bit mapping manner, the base station adds an 8-bit CRC to 00100000 and then sends it.

[0138] The terminal determines that the first information must be monitored in each monitoring window based on the sending parameters, and the second information needs to be monitored every two monitoring windows. The first information uses RM with a code rate of 1 / 4, and the second information uses 8-bit CRC and the maximum load is 8 bits. Therefore, the terminal monitors LP-WUS according to the sending parameters and monitors the second information. Assuming that the group index corresponding to the terminal is 3, the terminal monitors the paging message.

[0139] Example A8

[0140] Assume that the base station configures the sending parameters corresponding to the first information as: the time domain position is each monitoring window, the encoding method is RM with a code rate of 1 / 4, and the waveform generation method is OOK; configure the sending parameters corresponding to the second information as: the time domain position is every 2 monitoring windows, the first indication is used to indicate the addition of an 8-bit CRC, the maximum load is 6 bits, and the waveform generation method is OOK.

[0141] Assume that all terminals with group indexes 3 and 7 need to be woken up.

[0142] The base station determines to send the second information because it is assumed that the group index is mapped in a corresponding binary manner, and 011111 is added with an 8-bit CRC and then sent.

[0143] The terminal determines that the first information must be monitored in each monitoring window based on the sending parameters, and the second information needs to be monitored every two monitoring windows. The first information uses RM with a code rate of 1 / 4, and the second information uses 8-bit CRC and a maximum load of 6 bits. Therefore, the terminal monitors LP-WUS according to the sending parameters and monitors the second information. Assuming that the group index corresponding to the terminal is 3, the terminal monitors the paging message.

[0144] Example A9

[0145] Assume that the base station configures the sending parameters corresponding to the first information as: the time domain position is each monitoring window, the encoding method is Polar with a code rate of 1 / 4, and the waveform generation method is OOK; configure the sending parameters corresponding to the second information as: the time domain position is every 2 monitoring windows, the first indication is used to indicate the addition of an 8-bit CRC, the maximum load is 6 bits, and the waveform generation method is OOK.

[0146] Assume that the base station needs to wake up all terminals with group indexes 2, 3, and 7.

[0147] The base station determines to send the second information. Assuming that the group index is mapped in a corresponding binary manner and the maximum load is 6 bits, only two group indexes can be sent, and 010011 is added with an 8-bit CRC and then sent.

[0148] The terminal determines, based on the sending parameters, that the first information must be monitored in each monitoring window, and the second information must be monitored every two monitoring windows. The first information uses Polar with a code rate of 1 / 4, and the second information uses an 8-bit CRC and a maximum load of 6 bits. Therefore, the terminal monitors LP-WUS according to the sending parameters and monitors the second information. Assuming that the group index corresponding to the terminal is 3, the terminal monitors the paging message.

[0149] Example A10

[0150] Assume that the base station configures the sending parameters corresponding to the first information as: the time domain position is each monitoring window, the encoding method is RM with a code rate of 1 / 4, and the waveform generation method is OOK; the sending parameters corresponding to the second information are configured as: the time domain position is every 2 monitoring windows, the encoding method is Manchester encoding with a code rate of 1 / 2, the first indication is used to indicate the addition of an 8-bit CRC, the maximum load is 9 bits, and the waveform generation method is OOK.

[0151] Assume that terminals with group indexes 2, 3, and 7 need to be woken up.

[0152] The base station determines to send the second information. Since the maximum load is 9 bits, 3 group indexes can be sent. 010011111 is added with an 8-bit CRC and then Manchester-encoded and sent.

[0153] The terminal determines that the first information must be monitored in each monitoring window based on the sending parameters, and the second information needs to be monitored every 2 monitoring windows. The first information uses RM with a code rate of 1 / 4, and the second information uses 8-bit CRC and a maximum load of 9 bits, and uses Manchester coding with a code rate of 1 / 2. Therefore, the terminal monitors LP-WUS according to the sending parameters and monitors the second information.

[0154] Assuming that the group index corresponding to the terminal is 3, the terminal monitors the paging message.

[0155] Example A11

[0156] Assume that the base station configures the sending parameters corresponding to the first information as: the time domain position is each monitoring window, the encoding method is RM with a code rate of 1 / 4, and the waveform generation method is OFDM; the sending parameters corresponding to the second information are configured as: the time domain position is every 2 monitoring windows, the first indication is used to indicate the addition of an 8-bit CRC, the maximum load is 40 bits, and the waveform generation method is OOK.

[0157] Assume that terminal A and terminal B need to be awakened. The corresponding terminal index is 16 bits. Assume that terminal A is 1001000111110000 and terminal B is 1001000000001111.

[0158] The base station determines to send the second information. Since the second information contains the group index and the terminal index, and the maximum load is 40 bits, the second information can carry the wake-up indication of up to 2 terminals. Therefore, the 40-bit second information is 0000000010010001111100001001000000001111, and is sent after adding an 8-bit CRC.

[0159] Terminal A determines, based on the sending parameters, that it must monitor the first information in each monitoring window, and that it needs to monitor the second information every two monitoring windows. The first information uses RM with a code rate of 1 / 4, and the second information uses 8-bit CRC and a maximum load of 40 bits. Therefore, terminal A monitors LP-WUS based on the sending parameters and monitors the second information. Then, terminal A monitors its own index in the second information, and terminal A monitors the paging message.

[0160] Terminal B determines, based on the sending parameters, that it must monitor the first information in each monitoring window, and that it needs to monitor the second information every two monitoring windows. The first information uses RM with a code rate of 1 / 4, and the second information uses 8-bit CRC and a maximum load of 40 bits. Therefore, terminal B monitors LP-WUS based on the sending parameters and monitors the second information. Then, terminal B monitors its own index in the second information, and terminal B monitors the paging message.

[0161] Example A12

[0162] Assume that the base station configures the sending parameters corresponding to the first information as: the time domain position is each monitoring window, the encoding method is RM with a code rate of 1 / 4, and the waveform generation method is OFDM; the sending parameters corresponding to the second information are configured as: the time domain position is every 2 monitoring windows, the first indication is used to indicate the addition of an 8-bit CRC, the maximum load is 24 bits, and the waveform generation method is OOK.

[0163] Assume that terminal A and terminal B need to be awakened. The corresponding terminal index is 16 bits. Assume that terminal A is 1001000111110000 and terminal B is 1001000000001111.

[0164] The base station determines to send the second information. Since the second information contains the group index and the terminal index, and the maximum load is 24 bits, the second information can carry the wake-up indication of at most one terminal. Assuming that the number of groups is 8, the second information is 000000001001000111110000, which is sent in the monitoring window n after adding the 8-bit CRC. The second information can also be 0000001001000000001111, which is sent in the monitoring window n+2 after adding the 8-bit CRC.

[0165] Terminal A determines, based on the sending parameters, that it must monitor the first information in each monitoring window, and that it needs to monitor the second information every two monitoring windows. The first information uses RM with a code rate of 1 / 4, and the second information uses 8-bit CRC and has a maximum load of 24 bits. Therefore, terminal A monitors LP-WUS based on the sending parameters, and monitors the second information in monitoring window n. Then, terminal A monitors its own index in the second information, and terminal A monitors the paging message.

[0166] Terminal B determines, based on the sending parameters, that it must monitor the first information in each monitoring window, and that it needs to monitor the second information every two monitoring windows. The first information uses RM with a code rate of 1 / 4, and the second information uses 8-bit CRC and has a maximum load of 24 bits. Therefore, terminal B monitors LP-WUS based on the sending parameters. If the second information is monitored in monitoring window n, then terminal B does not detect its own index in the second information in monitoring window n. Terminal B continues to monitor LP-WUS, and if the second information is monitored in monitoring window n+2 and the monitored second information contains its own index, then terminal B monitors the paging message.

[0167] Example A13

[0168] Assume that the base station configures the transmission parameters corresponding to the first information as follows: the time domain position is each monitoring window, the encoding method is Manchester encoding with a code rate of 1 / 4, the first OOK is used for transmission, and frequency hopping is enabled; the transmission parameters corresponding to the second information are configured as follows: the time domain position is every 2 monitoring windows, the encoding method is Manchester encoding with a code rate of 1 / 4, the first indication is used to indicate the addition of an 8-bit CRC, the maximum load is 10 bits, the first OOK is used for transmission, and frequency hopping is enabled. The first OOK is an OOK that carries 2 bits of information on a time domain symbol, and the frequency hopping pattern is two predefined frequency domain positions.

[0169] Assume that terminals with group indexes 2, 3, and 7 need to be woken up.

[0170] The base station determines to send the second information. Because the maximum payload is 10 bits, three group indices can be sent. 010011111 is appended with a 1-bit 0 and then an 8-bit CRC, and then Manchester encoding is performed with a code rate of 1 / 4 before transmission. During transmission, frequency hopping is enabled. Because the code rate of Manchester encoding is 1 / 4 and one OOK time-domain symbol carries 2 bits of information, K1 = 1, that is, frequency hopping transmission is performed based on each time-domain symbol.

[0171] The terminal determines that the first information must be monitored in each monitoring window based on the sending parameters, and the second information needs to be monitored every 2 monitoring windows. The first information uses Manchester coding with a code rate of 1 / 4, and the second information uses an 8-bit CRC and a maximum load of 10 bits, and uses Manchester coding with a code rate of 1 / 4. Therefore, the terminal monitors LP-WUS according to the sending parameters and monitors the second information.

[0172] Assuming that the group index corresponding to the terminal is 3, the terminal monitors the paging message.

[0173] Example A14

[0174] Assume that the base station configures the transmission parameters corresponding to the first information as follows: the time domain position is each monitoring window, the coding method is Manchester coding with a code rate of 1 / 4, the first OOK is used for transmission, and frequency hopping is enabled; the transmission parameters corresponding to the second information are configured as follows: the time domain position is every 2 monitoring windows, the coding method is Manchester coding with a code rate of 1 / 2 and repetition coding with a code rate of 1 / 2, the first indication is used to indicate the addition of an 8-bit CRC, the maximum load is 10 bits, the first OOK is used for transmission, and frequency hopping is enabled. The first OOK is an OOK that carries 2 bits of information on a time domain symbol, and the frequency hopping pattern is two predefined frequency domain positions.

[0175] Assume that terminals with group indexes 2, 3, and 7 need to be woken up.

[0176] The base station determines to send the second information. Since the maximum payload is 10 bits, three group indices can be sent. 010011111 is appended with a 1-bit 0, followed by an 8-bit CRC, and then Manchester-encoded before transmission. Frequency hopping is enabled during transmission. Because rate-1 / 2 Manchester coding and rate-1 / 2 repetition coding are used, and one OOK time-domain symbol carries 2 bits of information, K1 = 2*(10+8) / 2 = 18, meaning frequency hopping transmission is performed based on 18 time-domain symbols.

[0177] The terminal determines, based on the sending parameters, that the first information must be monitored in each monitoring window, and the second information must be monitored every two monitoring windows. The first information uses Manchester coding with a code rate of 1 / 4, and the second information uses an 8-bit CRC and a maximum load of 10 bits, and uses Manchester coding with a code rate of 1 / 2 and 1 / 2 repetition coding. Therefore, the terminal monitors LP-WUS according to the sending parameters and monitors the second information.

[0178] Assuming that the group index corresponding to the terminal is 3, the terminal monitors the paging message.

[0179] As another example, taking the first set as a resource set consisting of resource positions corresponding to when the wake-up signal is sent as an example, the following examples B1 to B4 may be included.

[0180] Example B1

[0181] Taking the resource set 1 as an example, it can be seen from the above content that resource set 1 includes a first resource position (time domain position 1) and a second resource position (time domain position 2). Assume that the base station configures the sending parameters corresponding to the first resource position as follows: the information type includes earthquake and tsunami warning indication, commercial mobile alert service, system message change indication, full wake-up indication, stop wake-up signal detection indication, the encoding method is RM with a code rate of 1 / 4, and the waveform generation method is OOK; the sending parameters corresponding to the second resource position are configured as follows: the information type is a group wake-up indication, the first indication is used to indicate the addition of an 8-bit CRC, the mapping mode is non-continuous mapping, and the waveform generation method is OOK.

[0182] Assume that a system message change indication needs to be sent.

[0183] The base station places the system message change indication corresponding to position 1, that is, the information carried on the time domain resource 1 is 0100 (the position of each information is determined in order according to the information type, including earthquake and tsunami warning indication, commercial mobile alert service, system message change indication, full wake-up indication, and stop wake-up signal detection indication), and then performs RM encoding with a code rate of 1 / 4 and sends a low-power wake-up signal at the first resource position.

[0184] The terminal monitors LP-WUS at each resource position according to the sending parameters, that is, it monitors the earthquake and tsunami warning indication, commercial mobile alert service, system message change indication, full wake-up indication, and stop wake-up signal detection indication at time domain position 1, using RM with a code rate of 1 / 4, and monitors the group wake-up indication at time domain position 2. The second information uses CRC. The terminal monitors LP-WUS according to the sending parameters. If the system message change indication information is detected, the terminal receives the system message.

[0185] Example B2

[0186] Taking the resource set 2 as an example, it can be seen from the above content that resource set 2 includes a first resource position (time domain position 1). Assume that the base station configures the sending parameters corresponding to the first resource position as follows: the information type is earthquake and tsunami warning indication and commercial mobile alert service, system message change indication, stop wake-up signal detection indication, and group wake-up indication; the encoding method is Manchester encoding with a code rate of 1 / 4, and the waveform generation method is OOK.

[0187] Assume that all terminals with a group index of 3 need to be woken up.

[0188] Because the group wake-up indication information is sent in a bit-mapped manner, that is, in the order of earthquake and tsunami warning indication and commercial mobile alert service, system message change indication, stop wake-up signal detection indication, and group wake-up indication, the earthquake and tsunami warning indication and commercial mobile alert service, system message change indication, and stop wake-up signal detection indication are 1 bit. Assuming the total number of groups is 8, the group index is 3 bits. Therefore, the base station Manchester encodes 000011 with a code rate of 1 / 4 and sends it in the first resource position.

[0189] The terminal determines the monitoring of LP-WUS at each resource location based on the sending parameters, that is, the monitoring information type at time domain location 1 is earthquake and tsunami warning indication, commercial mobile alert service, system message change indication, stop wake-up signal detection indication and group wake-up indication. Assuming that the group index corresponding to the terminal is 3, the terminal monitors the paging message.

[0190] Example B3

[0191] Taking the resource set 3 as an example, it can be seen from the above content that resource set 3 includes a first resource position (time domain position 1, frequency domain position 1) and a second resource position (time domain position 2, frequency domain position 2). Assume that the base station configures the sending parameters corresponding to the first resource position as follows: the information type is earthquake and tsunami warning indication, commercial mobile alert service, system message change indication, stop wake-up signal detection indication, the encoding method is Manchester encoding with a code rate of 1 / 4, the second indication is used to indicate frequency hopping enable, and the waveform generation method is OOK; the sending parameters corresponding to the second resource are configured as follows: the information type is a wake-up indication of at least one terminal to be paged, the maximum load is 16 bits, and the waveform generation method is the first OOK, that is, OOK carrying 2 bits of information on a time domain symbol.

[0192] Assume that terminal A needs to be woken up, and the value of terminal A is 1001000111110000.

[0193] The base station sends a wake-up indication for terminal A on the second resource. Because the maximum payload corresponding to the second resource is 16 bits, 1001000111110000 is Manchester-encoded with a code rate of 1 / 4 and sent at the second resource position. Because frequency hopping is enabled, the encoding method is Manchester coding with a code rate of 1 / 4, and one time domain symbol carries 2 bits of information, K1 = 1, and the second indication is used to indicate that frequency hopping is enabled, and the frequency hopping positions are the preset two frequency domain positions.

[0194] Terminal A monitors the LP-WUS on the first resource and the second resource, detects its own index in the second information, and monitors the paging message.

[0195] Example B4

[0196] Taking resource set 2 as an example, it can be seen from the above content that resource set 2 includes a first resource position (time domain position 1). Assume that the base station configures the transmission parameters corresponding to the first resource position as follows: the information type is earthquake and tsunami warning indication and commercial mobile alert service, system message change indication, stop wake-up signal detection indication, and group wake-up indication; the encoding method is Manchester encoding with a code rate of 1 / 4, the waveform generation method is OOK, and the antenna configuration is antenna selection.

[0197] Assume that all terminals with a group index of 3 need to be woken up.

[0198] Because the group wake-up indication information is sent in a bit-mapped manner, that is, in the order of Earthquake and Tsunami Warning Indication and Commercial Mobile Alert Service, System Message Change Indication, Stop Wake-up Signal Detection Indication, and Group Wake-up Indication, Earthquake and Tsunami Warning Indication and Commercial Mobile Alert Service, System Message Change Indication, and Stop Wake-up Signal Detection Indication, each of which is 1 bit, and assuming there are 8 groups in total, the group index is 3 bits. Therefore, the base station Manchester encodes 000011 with a code rate of 1 / 4 and sends it in the first resource position, using multi-antenna selection, that is, selecting one from all configured antennas for transmission.

[0199] The terminal determines the monitoring of LP-WUS at each resource location based on the sending parameters, that is, the monitoring information type at time domain location 1 is earthquake and tsunami warning indication, commercial mobile alert service, system message change indication, stop wake-up signal detection indication and group wake-up indication. Assuming that the group index corresponding to the terminal is 3, the terminal monitors the paging message.

[0200] As another example, taking the first set as a load set consisting of load sizes corresponding to wake-up signals as an example, the following examples C1 to C3 may be included.

[0201] Example C1

[0202] Assuming that the load set is the above-mentioned load set 1, it can be seen from the above content that load set 1 includes a first load and a second load. Assuming L1=1, L2=4, the base station configures the sending parameters corresponding to the first load as follows: the information type is earthquake and tsunami warning indication, commercial mobile alert service, system message change indication, full wake-up indication, stop wake-up signal detection indication, the encoding method is RM with a code rate of 1 / 4, the time domain position is each monitoring window, and the waveform generation method is OOK; the sending parameters corresponding to the second load are configured as follows: the information type is group wake-up indication, the first indication is used to indicate the addition of an 8-bit CRC, the time domain position is every n monitoring windows, and the waveform generation method is OOK.

[0203] Assume that a system message change indication needs to be sent, and the size is 1 bit.

[0204] The base station uses the transmission parameters corresponding to the first load for transmission, that is, transmits within the most recent monitoring window, uses RM encoding with a code rate of 1 / 4 during transmission, and uses OOK waveform generation mode.

[0205] The terminal determines the monitoring of LP-WUS based on the sending parameters, that is, it monitors the first load in each monitoring window and monitors the second load every n monitoring windows. When monitoring the first load, RM with a code rate of 1 / 4 is used, and CRC is used when monitoring the second load. Therefore, if the terminal monitors the first load and the corresponding value is 1, the terminal receives the data.

[0206] Example C2

[0207] Assuming that the load set is the above-mentioned load set 2, it can be seen from the above content that load set 2 includes a first load, a second load and a third load. Assuming L1=1, L2=8, L3=48, the base station configures the sending parameters corresponding to the first load as follows: the coding mode is Manchester coding with a code rate of 1 / 4, the time domain position is time domain position 1, and the frequency domain position is frequency domain position 1; the sending parameters corresponding to the second load are configured as follows: the first indication is used to indicate the addition of an 8-bit CRC, the coding mode is Manchester coding with a code rate of 1 / 2, the time domain position is time domain position 2, the frequency domain position is frequency domain position 1, and the waveform generation mode is OOK; the sending parameters corresponding to the third load are configured as follows: the first indication is used to indicate the addition of an 8-bit CRC, the coding mode is Manchester coding with a code rate of 1 / 2, the time domain position is time domain position 3, the frequency domain position is frequency domain position 1, and the waveform generation mode is OOK.

[0208] Assume that all terminals with a group index of 3 need to be awakened, assume that information is sent in a bitmap manner, and the total number of groups is 8.

[0209] The base station uses the transmission parameters corresponding to the second load to send, that is, 00100000 is added with CRC, Manchester encoding is performed with a code rate of 1 / 2, and then sent at the time domain position of time domain position 2 and the frequency domain position of frequency domain position 1.

[0210] The terminal determines the monitoring of the LP-WUS according to the sending parameter, and monitors the LP-WUS using the sending parameter corresponding to the second load. If the group index corresponding to the terminal is 3, the terminal receives the paging message.

[0211] Example C3

[0212] Assuming that the load set is the above-mentioned load set 2, it can be seen from the above content that load set 2 includes the first load, the second load and the third load. Assuming L1=1, L2=8, L3=20, the base station configures the sending parameters corresponding to the first load as follows: the coding mode is Manchester coding with a code rate of 1 / 4, the time domain position is time domain position 1, the frequency domain position is frequency domain position 1, and the waveform generation mode is OOK; the sending parameters corresponding to the second load are configured as follows: the coding mode is Manchester coding with a code rate of 1 / 2, the time domain position is time domain position 2, the frequency domain position is frequency domain position 1, and the waveform generation mode is OOK; the sending parameters corresponding to the third load are configured as follows: the first indication is used to indicate the addition of an 8-bit CRC, the coding mode is Manchester coding with a code rate of 1 / 2, the time domain position is time domain position 3, the frequency domain position is frequency domain position 1, and the waveform generation mode is OOK.

[0213] Assume that terminal A and terminal B need to be awakened. The corresponding terminal index is 8 bits. Assume that terminal A is 10010001 and terminal B is 11110000.

[0214] The base station uses the sending parameters corresponding to the third load to send. Because the bit overhead corresponding to the third load is 20, the indexes of terminal A and terminal B are cascaded and then 4 zeros are added, that is, 10010001111100000000 is added with CRC, and then encoded using Manchester coding with a code rate of 1 / 2 and sent at time domain position 3 and frequency domain position 1.

[0215] Terminal A and terminal B determine the monitoring of LP-WUS based on the sending parameters, monitor LP-WUS using the sending parameters corresponding to the third load, and resolve the corresponding terminal index. Terminal A and terminal B receive the paging message.

[0216] As another example, taking the first set as a format set consisting of formats corresponding to when a wake-up signal is sent as an example, the following examples D1 and D2 may be included.

[0217] Example D1

[0218] Assume that the format set is composed of {format 1 and format 2}, the first sending parameter in format 1 is fixed, and take the first sending parameter as Manchester encoding with coding of 1 / 2, the waveform generation mode is OOK, and the beam direction is direction 5 as an example; format 2 is Manchester encoding with coding of 1 / 4, the beam direction is direction 4, the first indication is used to indicate the addition of CRC, and the waveform generation mode is OOK; the base station configures the sending parameters corresponding to format 1 as follows: the information type is earthquake and tsunami warning indication, commercial mobile alert service, system message change indication, full wake-up indication, stop wake-up signal detection indication, the time domain position is that the frequency hopping of each monitoring window is configured to be disabled, and the maximum load is 4 bits; the sending parameters corresponding to the second format are configured as follows: the information type is the wake-up indication of at least one terminal to be paged, the time domain position is every n monitoring windows, and the maximum load is 16 bits.

[0219] Assume that terminal A and terminal B need to be awakened. The corresponding terminal index is 8 bits. Assume that terminal A is 10010001 and terminal B is 11110000.

[0220] The base station uses the transmission parameters corresponding to format 2 to send. Since the maximum load corresponding to format 2 is 16 bits, the indexes of terminal A and terminal B are cascaded, CRC is added, and then Manchester encoding with a code rate of 1 / 4 is used to encode the data and then sent within the nearest transmittable monitoring window. The beam direction used during transmission is 4.

[0221] Terminal A and terminal B determine the monitoring of LP-WUS based on the sending parameters. When the LP-WUS is monitored using the sending parameters corresponding to format 2 and the corresponding terminal index is parsed, terminal A and terminal B receive the paging message.

[0222] Example D2

[0223] Assume that the format set is composed of {format 1 and format 2}, the first sending parameter in format 1 is fixed, and the first sending parameter is Manchester coding with a code rate of 1 / 2 and a beam direction of {direction 1, direction 2} as an example; format 2 is Manchester coding with a code rate of 1 / 4, the beam direction is {direction 1, direction 2, direction 3, direction 4}, and CRC is added; the base station configures the sending parameters corresponding to format 1 as follows: the information type is earthquake and tsunami warning indication, commercial mobile alert service, system message change indication, full wake-up indication, stop wake-up signal detection indication, the time domain position is each monitoring window, the waveform generation mode is OOK, the frequency hopping configuration is disabled, and the maximum load is 4 bits; the sending parameters corresponding to the second format are configured as follows: the information type is the wake-up indication of at least one terminal to be paged, the time domain position is every n monitoring windows, and the maximum load is 16 bits.

[0224] Assume that terminal A and terminal B need to be awakened. The corresponding terminal index is 8 bits. Assume that terminal A is 10010001 and terminal B is 11110000.

[0225] The base station uses the transmission parameters corresponding to format 2 for transmission. Since the maximum load corresponding to format 2 is 16 bits, the indexes of terminal A and terminal B are concatenated and CRC is added, and then encoded using Manchester coding with a code rate of 1 / 4 and sent within the nearest transmittable monitoring window. The beam directions used during transmission are {direction 1, direction 2, direction 3, direction 4}.

[0226] Terminal A and terminal B determine the monitoring of LP-WUS based on the sending parameters. When the LP-WUS is monitored using the sending parameters corresponding to format 2 and the corresponding terminal index is parsed, terminal A and terminal B receive the paging message.
