Description

Signal sending method, network equipment and terminal equipment

Technical Field

The present application relates to the field of wireless communication technologies, and in particular, to a signal transmission method, a network device, and a terminal device.

Background

In a wireless communication system, a network device periodically transmits a paging signal indicating whether a terminal device should be switched from an idle state to a connected state in order to exchange service data with the terminal device. The terminal device in an idle state wakes up periodically to detect a paging signal, a period of waking up periodically is called a Discontinuous Reception (DRX) period, and a location of waking up is called a Paging Occasion (PO). The terminal detects a Physical Downlink Control Channel (PDCCH) in a search space initiated at the PO location to determine whether it is paged by the network device, and if so, enters a connected state.

In a narrowband internet of things (NB-IoT) system, a network device is provided with a paging indication signal in front of a PO location to indicate whether a terminal device needs to wake up at the PO location. Fig. 1 illustrates a manner in which a network device transmits a paging indication signal in the prior art, where a Wake Up Signal (WUS)/sleep signal (GTS) periodically occurs before some POs and a WUS/Discontinuous Transmission (DTX) occurs before the rest POs. The network device instructs the terminal device of the maximum signal length and location of the paging indicator signal for the terminal device to detect the signal.

At the position of the WUS/GTS, if the terminal detects a WUS signal or a GTS signal in the period of the maximum signal length, corresponding processing is carried out, if the signals in the period of the maximum signal length are detected, the WUS signal or the GTS signal is not detected yet, the terminal considers that the terminal moves out of the cell, and then operations such as cell measurement, reselection and the like are triggered. Since the maximum signal length indicated by the network device is usually greater than the actual signal lengths of the WUS signal and the GTS signal, the larger the maximum signal length indicated by the network device is, the longer the terminal detects the signal is, and the larger the power consumption is. Particularly, in an actual scene, the actual signal lengths of the WUS signal and the GTS signal are different, but the network device often transmits the GTS signal, so that a uniform maximum signal length is indicated for the WUS signal and the GTS signal, and power consumption when the terminal detects the GTS signal is also significantly increased.

Therefore, there is a need for a signal transmission method for solving the technical problem of large power consumption when a terminal detects a paging indicator signal in the prior art.

Disclosure of Invention

An object of the embodiments of the present application is to provide a signal transmission method, a network device, and a terminal device, which are used to reduce power consumption when the terminal device detects a paging indication signal.

In a first aspect, an embodiment of the present application provides a signal sending method, including:

the method comprises the steps that network equipment generates first indication information and second indication information, wherein the first indication information is used for indicating terminal equipment to determine a first detection window length of a sleep signal, and the second indication information is used for indicating the terminal equipment to determine a second detection window length of a wake-up signal; the wake-up signal is used for indicating that the terminal equipment needs to monitor a Physical Downlink Control Channel (PDCCH) during a paging opportunity, and the sleep signal is used for indicating that the terminal equipment does not need to monitor the PDCCH during the paging opportunity;

in this embodiment, the network device may generate two indication messages, where the first indication message is used to instruct the terminal device to determine a first detection window length of the sleep signal, the second indication message is used to instruct the terminal device to determine a second detection window length of the wake-up signal, thus, after the network device sends the first indication information and the second indication information, the terminal device can determine the first detection window length according to the first indication information, determining a second detection window length according to the second indication information, and further detecting the sleep signal within the first detection window length, and detecting the wake-up signal at the length of the second detection window, thereby avoiding the technical problem that in the prior art, the network device only configures the maximum signal length of the paging indication signal, and no matter whether the network device sends the sleep signal or the wake-up signal, the terminal device needs to detect the signal within the maximum signal length to cause larger power consumption.

In one possible design, the first detection window length is less than the second detection window length.

In consideration of the fact that in practical application, the probability that the network device pages the terminal device or the system message is changed may be relatively low, and thus the network device may not send the PDCCH during most paging occasions, that is, the probability that the network device sends the sleep signal at the position of the wake-up signal/sleep signal is higher, and the probability that the network device does not send any signal at the position of the wake-up signal/discontinuous transmission is higher.

Optionally, the first indication information is the length of the first detection window, and the second indication information is the length of the second detection window.

Optionally, the first indication information is the length of the first detection window, and the second indication information is a ratio or a difference between the length of the second detection window and the length of the first detection window; alternatively, the first and second electrodes may be,

the first indication information is a ratio or a difference between the length of the first detection window and the length of the second detection window, and the second indication information is the length of the second detection window.

Thus, the network device may indicate the respective detection window lengths of the sleep signal and the wake-up signal in plain text in both the first indication information and the second indication information, or may indicate the detection window length of the paging indication signal corresponding to one of the indication information in plain text only in one of the indication information, and indicate the ratio or difference between the two detection window lengths in the other indication information, and the terminal device determines the other detection window length according to the detection window length given in the plain text in the indication information, the ratio or difference between the two detection window lengths, thereby effectively improving the flexibility of the network device to configure the indication information.

Optionally, the first indication information is a ratio of the first detection window length to a set repetition number, and the second indication information is a ratio of the second detection window length to the set repetition number, where the set repetition number is a maximum repetition number of the PDCCH during the paging opportunity;

optionally, the first indication information is a ratio of the length of the first detection window to a set repetition number, and the second indication information is a ratio or a difference between the length of the second detection window and the length of the first detection window; alternatively, the first and second electrodes may be,

The first indication information is the ratio or difference of the length of the first detection window and the length of the second detection window, and the second indication information is the ratio of the length of the second detection window to the set repetition times; wherein the set repetition number is a maximum repetition number of the PDCCH during the paging opportunity.

In the embodiment of the application, the network device can further expand the mode of configuring the indication information for the network device based on the maximum repetition times of the PDCCH during the paging opportunity, thereby effectively improving the flexibility of configuring the indication information for the network device.

In one possible design, the network device may send first coverage indication information indicating a coverage of the sleep signal.

In the embodiment of the application, the network device indicates the coverage area of the sleep signal by sending the first coverage indication information. Therefore, the network device can send the dormancy signal only suitable for part of the terminal devices (namely, the terminal devices within the coverage range of the dormancy signal), and accordingly, the terminal devices can detect the dormancy signal according to whether the terminal devices belong to the coverage range of the dormancy signal, so that the resource overhead of the network device for sending the dormancy signal is effectively reduced, and the negative influence of the overlarge resource overhead of the network device for sending the dormancy signal on the terminal devices is avoided.

Optionally, the first coverage indication information is a first signal attenuation value, and the first signal attenuation value is used for determining that the terminal device is located in the coverage of the sleep signal when the attenuation value of the signal received from the network device is smaller than the first signal attenuation value.

In the embodiment of the application, the network device may indicate the coverage of the sleep signal by giving the first signal attenuation value. The attenuation value of the signal sent by the network equipment received by the terminal equipment can be used for measuring the coverage condition of the terminal equipment, and the smaller the attenuation value of the signal is, the better the coverage condition of the terminal equipment is, so that the terminal equipment receiving the signal from the network equipment with the attenuation value smaller than the first signal attenuation value is set to be positioned in the coverage range of the sleep signal in the embodiment of the application, so that the sleep signal sent by the network equipment is only suitable for the terminal equipment with the better coverage condition, and the technical problem that the resource overhead of the network equipment for sending the sleep signal is too large and the scheduling of other terminal equipment is influenced in order to meet the detection performance requirement of the terminal equipment with the poorer coverage condition on the sleep signal is solved.

Optionally, the first coverage indication information is first power, and the first power is used for determining that the terminal device is located in a coverage of the sleep signal when reference signal received power, RSRP, is greater than the first power.

In the embodiment of the application, the network device may indicate the coverage of the sleep signal by giving the first power. Since the RSRP of the terminal device represents the received strength of the signal sent by the network device, the RSRP can also be used to measure the coverage of the terminal device, and a larger RSRP indicates a better coverage of the terminal device. Therefore, in the embodiment of the present application, the terminal device with RSRP greater than the first power is set to be located in the coverage area of the sleep signal, and the sleep signal sent by the network device is only applicable to the terminal device with better coverage, so as to avoid the technical problem that the resource overhead of the network device for sending the sleep signal is too large to affect the scheduling of other terminal devices in order to meet the detection performance requirement of the terminal device with poorer coverage on the sleep signal.

Optionally, the first coverage indication information is a first repetition number, where the first repetition number is used for determining that the terminal device is located in the coverage of the dormant signal when the number of repeated receptions of the terminal device that correctly receives the PDCCH is smaller than the first repetition number.

In the embodiment of the present application, the network device may further indicate the coverage of the sleep signal by giving the first number of repetitions. The repeated receiving times of the PDCCH correctly received by the terminal equipment can also be used for measuring the coverage condition of the terminal equipment, and the smaller the repeated receiving times is, the better the coverage condition of the terminal equipment is. Therefore, in the embodiment of the present application, the terminal device with the repeated receiving times smaller than the first repeated times is set to be located in the coverage area of the sleep signal, and the purpose that the sleep signal sent by the network device is only suitable for the terminal device with better coverage can also be achieved, so as to avoid the technical problem that the resource overhead of the network device for sending the sleep signal is too large to influence the scheduling of other terminal devices in order to meet the detection performance requirement of the terminal device with poorer coverage on the sleep signal.

In one possible design, the network device may send second coverage indication information indicating a coverage of the wake-up signal.

In this embodiment, the network device may further send second coverage indication information indicating a coverage area of the wake-up signal. Therefore, the network device can send out the wake-up signal only suitable for part of the terminal devices (namely, the terminal devices within the coverage range of the wake-up signal), and accordingly, the terminal devices can detect the wake-up signal according to whether the terminal devices belong to the coverage range of the wake-up signal, so that the resource overhead of the network device for sending the wake-up signal is effectively reduced, and the negative influence of the excessive resource overhead of the network device for sending the wake-up signal on the terminal devices is avoided.

Optionally, the second coverage indication information is a second signal attenuation value, and the second signal attenuation value is used for determining that the terminal device is located within the coverage of the wake-up signal when the attenuation value of the signal received from the network device is smaller than the second signal attenuation value.

Similar to the manner of indicating the coverage of the sleep signal, in the embodiment of the present application, the network device may indicate the coverage of the wake-up signal by giving the second signal attenuation value, and set the terminal device whose signal attenuation value is smaller than the second signal attenuation value to be located in the coverage of the wake-up signal, so that the wake-up signal sent by the network device is only suitable for the terminal device with better coverage, thereby avoiding the technical problem that the resource overhead of sending the wake-up signal by the network device is too large to affect the scheduling of other terminal devices in order to meet the performance requirement of the terminal device with poorer coverage on the detection of the wake-up signal.

Optionally, the first coverage indication information is a first signal attenuation value, and the first signal attenuation value is used for determining that the terminal device is located in the coverage of the sleep signal when the attenuation value of the signal received from the network device is smaller than the first signal attenuation value;

The second signal attenuation value is greater than the first signal attenuation value.

In the embodiment of the present application, if the network device indicates the coverage of both the sleep signal and the wake signal, the network device may use the same type of network parameters to indicate the coverage of both the sleep signal and the wake signal. For example, the attenuation values are used to indicate. Further, the second signal attenuation value indicating the coverage of the wake-up signal may be greater than the first attenuation value. In this example, the wake-up signal has a greater coverage area than the sleep signal, which may cover terminal devices with greater signal attenuation values. There may be some terminal devices with poor coverage that do not belong to the coverage of the sleep signal and do not use the sleep signal, but may use the wake-up signal because the signal attenuation value of these terminal devices is still smaller than the second signal attenuation value and is within the coverage of the wake-up signal. Optionally, the second coverage indication information is a second power, and the second power is used for determining that the terminal device is located within a coverage of the wake-up signal when the RSRP is greater than the second power.

In the embodiment of the application, the network device can indicate the coverage of the wake-up signal by giving the second power, and the terminal device with the RSRP greater than the second power is set to be located in the coverage of the wake-up signal, so that the wake-up signal sent by the network device is only suitable for the terminal device with better coverage, and the technical problem that the resource overhead of the network device for sending the wake-up signal is too large to influence the scheduling of other terminal devices in order to meet the detection performance requirement of the terminal device with poorer coverage on the wake-up signal is avoided.

Optionally, the first coverage indication information is first power, and the first power is used for determining that the terminal device is located within a coverage of the sleep signal when RSRP is greater than the first power;

the second power is less than the first power.

In the embodiment of the present application, if the network device indicates the coverage of both the sleep signal and the wake signal, the network device may use the same type of network parameters to indicate the coverage of both the sleep signal and the wake signal. For example, power values are used for indication. Further, the second power used to indicate the coverage of the wake-up signal may be related to the first power used to indicate the sleep signal, e.g., the second power may be a certain power value less than the first power. In this scenario, the wake-up signal has a larger coverage area than the sleep signal, which may cover terminal devices with smaller RSRP. There may be some terminal devices with poor coverage that do not belong to the coverage of the sleep signal, do not use the sleep signal, but may use the wake-up signal because their RSRP value is still greater than the second power, but is within the coverage of the wake-up signal.

Optionally, the second coverage indication information is a second repetition number, and the second repetition number is used for determining that the terminal device is located in the coverage of the wake-up signal when the number of repeated receptions of the terminal device that correctly receives the PDCCH is smaller than the second repetition number.

In the embodiment of the application, the network device may further indicate a coverage of the wake-up signal by giving the second number of repeated receptions, and set the terminal device that correctly receives the PDCCH and has a number of repeated receptions that is smaller than the second number of repeated receptions to be within the coverage of the wake-up signal, so that the wake-up signal sent by the network device is only suitable for the terminal device with better coverage, thereby avoiding the technical problem that the resource overhead of the network device for sending the wake-up signal is too large to affect the scheduling of other terminal devices in order to meet the performance requirement of the terminal device with poorer coverage on the wake-up signal.

Optionally, the first coverage indication information is a first repetition number, where the first repetition number is used for determining that the terminal device is located in a coverage area of the dormant signal when the repeated reception number of correctly receiving the PDCCH by the terminal device is smaller than the first repetition number;

The second number of repetitions is greater than the first number of repetitions.

In this embodiment, if the network device indicates the coverage of both the sleep signal and the wake-up signal, the network device may use the repetition times to indicate the coverage of both the sleep signal and the wake-up signal. The second number of repetitions used for indicating the coverage of the wake-up signal may be related to the first number of repetitions used for indicating the coverage of the sleep signal, for example, the second number of repetitions may be greater than the first number of repetitions, so that the wake-up signal indicated by the second number of repetitions may cover a terminal device with a greater number of repetitions than the sleep signal. There may be some terminal devices with poor coverage that do not belong to the coverage of the sleep signal and cannot use the sleep signal, but the terminal devices may use the wake-up signal because the number of repetitions of the terminal devices is still less than the second number of repetitions and is within the coverage of the wake-up signal.

In one possible design, a network device may send first activation indication information indicating whether the terminal device determines whether the terminal device is located in a coverage area of a sleep signal indicated by the first coverage indication information according to the first coverage indication information.

In this embodiment of the present application, a network device may trigger, by broadcasting or sending a dedicated signaling, whether a terminal device determines, according to first coverage indication information, whether the terminal device is located within a coverage of a sleep signal indicated by the first coverage indication information. Although the network device has set the coverage for the sleep signal, the network device does not enable the coverage set for the sleep signal until the network device sends the first activation indication information. At this time, all terminal devices accessing the cell can use the sleep signal sent by the network device regardless of the coverage of the terminal device. Once the network device sends the first activation indication information, the network device indicates that the network device starts a coverage range set for the sleep signal, the network device limits the applicability of the sleep signal to the terminal device located in the coverage range of the sleep signal according to the coverage condition of each terminal device accessing the cell, and accordingly, the terminal device can detect the sleep signal according to whether the terminal device is located in the coverage range of the sleep signal, so that the resource overhead of the network device for sending the sleep signal can be reduced, and the negative influence of the excessive resource overhead of the network device for sending the sleep signal on the system can be avoided.

In one possible design, the network device may send second activation indication information, where the second activation indication information is used to indicate whether the terminal device determines whether the terminal device is located in a coverage area of a wake-up signal indicated by the second coverage indication information according to the second coverage indication information.

In this embodiment of the present application, the network device may further trigger, by broadcasting or sending a dedicated signaling, whether the terminal device determines whether the terminal device is located in a coverage area of the wake-up signal indicated by the second coverage indication information according to the second coverage indication information. Similar to the principle that the network device sends the first activation indication information, although the network device has set a coverage for the wake-up signal, the network device does not enable the coverage set for the wake-up signal before the network device sends the second activation indication information. At this time, all terminal devices accessing the cell can use the wake-up signal sent by the network device, regardless of the coverage of the terminal device. Once the network device sends the second activation indication information, the network device indicates that the network device starts a coverage set for the wake-up signal, the network device limits the applicability of the wake-up signal to the terminal device located in the coverage of the wake-up signal according to the coverage of each terminal device accessing the cell, and accordingly, the terminal device can detect the wake-up signal according to whether the terminal device is located in the coverage of the wake-up signal, so that the resource overhead of sending the wake-up signal by the network device can be reduced, and the negative influence of the excessive resource overhead of sending the wake-up signal on the system can be avoided.

In one possible design, the network device generates first duration indication information and second duration indication information, the first duration indication information being used for indicating a terminal device to determine a maximum duration of the wake-up signal, and the second duration indication information being used for indicating the terminal device to determine a minimum duration of the wake-up signal;

the network device sends the first duration indication information and the second duration indication information.

In the embodiment of the application, the network device generates and sends the first duration indication information and the second duration indication information, so that the terminal device can acquire the maximum duration and the minimum duration of the wake-up signal, and further can judge whether cell synchronization can be performed through the wake-up signal, thereby avoiding the technical problems that in the prior art, the terminal device only acquires the maximum signal length of the paging indication signal and tries to perform cell synchronization through the wake-up signal under the scene that the actual sending length of the paging indication signal is not known, but the actual sending length of the wake-up signal is not enough to perform cell synchronization and waste power consumption.

Optionally, the first duration indication information is the maximum duration, and the second duration indication information is the minimum duration.

Optionally, the first duration indication information is the maximum duration, and the second duration indication information is a ratio or a difference between the minimum duration and the maximum duration; alternatively, the first and second electrodes may be,

In one possible design, the network device may generate third duration indication information for indicating a maximum duration for a terminal device to determine the sleep signal and fourth duration indication information for indicating a minimum duration for the terminal device to determine the sleep signal;

the network device sends the third duration indication information and the fourth duration indication information.

The network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

Some scenarios in the embodiment of the present application are described by taking a scenario of an NB-IoT network in a wireless communication network as an example, it should be noted that the scheme in the embodiment of the present application may also be applied to other wireless communication networks, and corresponding names may also be replaced with names of corresponding functions in other wireless communication networks.

With reference to the above description, as shown in fig. 3, a schematic flow chart of a signal transmission method provided in an embodiment of the present application is shown.

Referring to fig. 3, the method includes:

step S301: the network equipment generates first indication information and second indication information;

step S302: the network equipment sends first indication information and second indication information;

step S303: the terminal equipment receives first indication information and second indication information sent by network equipment;

Step S304: the terminal equipment determines the length of a first detection window of the sleep signal according to the first indication information; and determining the length of a second detection window of the wake-up signal according to the second indication information.

In this embodiment of the application, the wake-up signal and the sleep signal are two paging indication signals sent by the network device, where the wake-up signal is used to indicate that the terminal device needs to wake up and monitor the PDCCH during a subsequent paging opportunity, and the sleep signal is used to indicate that the terminal device does not need to monitor the PDCCH during the paging opportunity, and the terminal device may continue to be in a sleep state. In this embodiment of the present application, the wake-up signal and the sleep signal may be distinguished by different sequences and code division, or may be distinguished by time division, frequency division, and space division, which is not specifically limited in this application.

It should be noted that the PDCCH described in the embodiment of the present application includes, but is not limited to: a Narrowband Physical Downlink Control Channel (NPDCCH), a machine-type communication physical downlink control channel (MPDCCH), and an enhanced physical downlink control channel (ePDCCH). For the sake of simplicity, NPDCCH will be described as an example.

The network equipment can also simultaneously use two signal transmission types of wake-up signal/sleep signal and wake-up signal/discontinuous transmission to transmit the paging indication signal, the wake-up signal/sleep signal is periodically generated before some pagers meet, the wake-up signal/discontinuous transmission is generated before other pagers meet, the repetition period of the wake-up signal/sleep signal is integral multiple of the discontinuous receiving period, and the terminal equipment can utilize the wake-up signal/sleep signal which repeatedly occurs to carry out cell synchronization and confirmation. At the position where the wake-up signal/sleep signal appears, if NPDCCH exists in the paging opportunity (for example, the network device needs to page the terminal device or the system message is changed), the network device may send the wake-up signal at the position, otherwise, send the sleep signal. At the location where the wake-up signal/discontinuous transmission occurs, the network device may transmit the wake-up signal at that location if NPDCCH is present in the subsequent paging opportunity, otherwise no signal is transmitted.

In a specific implementation of step S301, the first indication information generated by the network device is used to instruct the terminal device to determine a first detection window length of the sleep signal, where the first detection window length is a maximum signal length or a maximum duration (i.e., configured maximum duration of GTS) configured for the sleep signal by the network device, and is used for the terminal device to detect the sleep signal within the detection window length.

The second indication information generated by the network device is used to instruct the terminal device to determine a second detection window length of the wake-up signal, where the second detection window length is a maximum signal length or a maximum duration (i.e., a configured maximum duration of WUS) configured for the wake-up signal by the network device, and is used for the terminal device to detect the wake-up signal within the detection window length.

Fig. 4 exemplarily shows a first detection window length and a second detection window length in the embodiment of the present application, and as shown in fig. 4, the first detection window length is equal to or greater than an actual signal length (GTS actual duration) of a sleep signal, and the second detection window length is equal to or greater than an actual signal length (WUS actual duration) of a wake-up signal.

It should be noted that, in the embodiment of the present application, the length of the first detection window may be the same as that of the second detection window, or may be different from that of the second detection window, which is not specifically limited in the present application. Optionally, the network device sets the first detection window length and the second detection window length to be different.

Therefore, when the terminal device detects the paging indication signal, if the corresponding paging indication signal is detected in a smaller detection window length, the signal does not need to be detected in a larger detection window length continuously, so that the power consumption of the terminal device for detecting the paging indication signal can be effectively reduced, and the technical problem that in the prior art, the network device only configures the maximum signal length of the paging indication signal, and no matter whether the network device sends a sleep signal or a wake-up signal, the terminal device needs to detect the signal in the maximum signal length, so that the power consumption is larger is solved.

In one possible design, the first detection window length of the network device configuration is smaller than the second detection window length. In practical applications, the probability of the network device paging the terminal device or the system message change may be relatively low, and thus the network device may not send the NPDCCH during most paging opportunities, that is, at the position of the wake-up signal/sleep signal, the probability of the network device sending the sleep signal is higher, and at the position of the wake-up signal/discontinuous transmission, the probability of the network device not sending any signal is relatively high. Considering that the actual signal length of the sleep signal may be smaller than the actual signal length of the wake-up signal, in the embodiment of the present application, the length of the first detection window is set to be smaller than the length of the second detection window, which can effectively reduce the resource overhead of the network device for sending the sleep signal, and reduce the power consumption of the terminal device for detecting the sleep signal.

In the embodiment of the application, the network device may generate the first indication information and the second indication information in a plurality of ways. For example, in one possible design, the network device may indicate the first detection window length in plaintext in the first indication information, and indicate the second detection window length in plaintext in the second indication information, in this example, the first indication information is the first detection window length, and the second indication information is the second detection window length.

In another possible design, the network device may indicate the detection window length corresponding to the indication information in plain text only in one of the indication information, and indicate a ratio or a difference between another detection window length and a previous detection window length in another indication information, so that the terminal device may determine another detection window length according to the detection window length indicated in plain text, the ratio or the difference between the two detection window lengths. For example, the network device may set the first indication information as a first detection window length, set the second indication information as a ratio or a difference of a second detection window length relative to the first detection window length, and after receiving the first indication information and the second indication information, the terminal device may multiply the first detection window length, the second detection window length, and the ratio of the first detection window length, and determine the product as the second detection window length, or may determine a sum of the first detection window length, the second detection window length, and the difference of the first detection window length, and the second detection window length, as the second detection window length. When the difference is positive, it may indicate that the second detection window length is greater than the first detection window length, and when the difference is negative, it may indicate that the second detection window length is less than the first detection window length. Or, the network device may further set the first indication information as a ratio or a difference between the length of the first detection window and the length of the second detection window, and set the second indication information as the length of the second detection window.

In another possible design, the network device may indicate, in plain text, a ratio of the length of the first detection window to the set number of repetitions in the first indication information, and indicate, in plain text, a ratio of the length of the second detection window to the set number of repetitions in the second indication information, that is, the first indication information is a ratio of the length of the first detection window to the set number of repetitions, and the second indication information is a ratio of the length of the second detection window to the set number of repetitions. Wherein, the value of the set repetition number can be the maximum repetition number of the NPDCCH during the paging opportunity.

For example, the value of the set repetition number may be one of {1,2,4,8,16,32,64,128,256,512,1024,2048} and the like, and the unit is a valid subframe (i.e., valid subframe). The first detection window length and the second detection window length may both be the set number of repetitions multiplied by a ratio, which may be

One of them. It should be noted that the ratio corresponding to the length of the first detection window may be the same as or different from the ratio corresponding to the length of the second detection window, and the application does not specifically limit this.

If the network device sets the ratio corresponding to the first detection window length to be the same as the ratio corresponding to the second detection window length, it indicates that the network device sets the first detection window length to be the same as the second detection window length, otherwise, if the network device sets the ratio corresponding to the first detection window length to be different from the ratio corresponding to the second detection window length, the terminal device determines that the first detection window length and the second detection window length are different according to the set repetition times and the ratios indicated in the first indication information and the second indication information.

Further, the network device may set a ratio corresponding to the first detection window length to be smaller than a ratio corresponding to the second detection window length, so that the first detection window length configured by the network device is smaller than the second detection window length, thereby effectively reducing resource overhead of the network device for sending the sleep signal, and reducing power consumption of the terminal device for detecting the sleep signal.

In another possible design, the network device may indicate, in plain text, only one of the pieces of indication information, a ratio of a length of the detection window corresponding to the piece of indication information to the set number of repetitions, and indicate, in the other piece of indication information, a ratio or a difference between a length of the other detection window and a length of a previous detection window, so that the terminal device may determine the length of the other detection window according to the ratio of the length of the detection window indicated in plain text to the set number of repetitions, the ratio or the difference between the lengths of the two detection windows.

For example, the network device may set the first indication information as a ratio of a first detection window length to a set repetition number, and set the second indication information as a ratio or a difference of a second detection window length to the first detection window length, and after receiving the first indication information and the second indication information, the terminal device may determine the first detection window length according to the set repetition number, the ratio of the first detection window length to the set repetition number; and determining the product of the first detection window length, the second detection window length and the ratio of the first detection window length as the second detection window length, or determining the sum of the first detection window length, the second detection window length and the difference of the first detection window length as the second detection window length. When the difference is positive, it may indicate that the second detection window length is greater than the first detection window length, and when the difference is negative, it may indicate that the second detection window length is less than the first detection window length.

For another example, the network device may further set the first indication information as a ratio or a difference between the length of the first detection window and the length of the second detection window, and set the second indication information as a ratio between the length of the second detection window and the set repetition number.

In this embodiment, the network device may further generate the first indication information and the second indication information according to other variation schemes that can be derived or extended based on the above manners, which is not particularly limited in this application. Based on the multiple generation modes, the network device can select the mode for generating the first indication information and the second indication information according to the actual situation that the terminal device accesses the network device. Therefore, the network equipment can effectively improve the flexibility of the network equipment for configuring the indication information and improve the system performance by setting various indication information generation modes.

In a specific implementation of step S302, the network device may send the first indication information and the second indication information through broadcast signaling of the cell.

It should be noted that, in this embodiment of the application, the network device may send the first indication information and the second indication information in the same broadcast signaling, or may send the first indication information and the second indication information in different broadcast signaling respectively. For example, the network device sends the first indication information and the second indication information respectively, the sending order of the two indication information is not specifically limited in the embodiment of the present application, and the first indication information may be sent first and then the second indication information is sent, or conversely, the second indication information may be sent first and then the first indication information is sent.

Further, in order to facilitate the terminal device to detect the paging indicator, the network device may also indicate a time domain position of the paging indicator (e.g., where the wake-up signal or the sleep signal is located before the paging opportunity) in the broadcast signaling, which is not described herein again.

In the specific implementation of steps S303 and S304, after receiving the first indication information and the second indication information, the terminal device may determine the first detection window length and the second detection window length according to the above principle, and detect the signal sent by the network device based on the determined first detection window length and the determined second detection window length.

In the embodiment of the present application, if the length of the first detection window is different from the length of the second detection window, when the terminal device detects the paging indicator, at the position of the wake-up signal/sleep signal, if the corresponding paging indicator is not detected within a smaller detection window length, the terminal device continues to detect the paging indicator within a larger detection window length, and if the corresponding paging indicator is not detected within a larger detection window length, the terminal device is considered to have moved out of the cell, so that operations such as cell measurement and cell reselection can be triggered.

Based on the message sending method in steps S301 to S304, the present application also provides a specific embodiment of the message sending method.

In this embodiment, the network device may also indicate the coverage (also referred to as coverage capability or applicability) of the paging indicator signals of both types, i.e., wake-up signal and sleep signal. This embodiment will be described in detail below.

Fig. 5 is a schematic flow chart of a signal sending method according to this embodiment.

Referring to fig. 5, the method further includes:

step S501: the network equipment sends first coverage indication information and/or sends second coverage indication information;

step S502: the terminal equipment receives first coverage indication information sent by the network equipment, and determines the coverage range of the sleep signal according to the first coverage indication information; and/or the terminal equipment receives second coverage indication information sent by the network equipment, and determines the coverage range of the wake-up signal according to the second coverage indication information.

Step S503: the terminal device detects the signal sent by the network device.

In an application scenario, in order to meet a detection performance requirement of a terminal device with a poor coverage on a paging indicator, a network device generally needs to increase an actual signal length of the paging indicator, and the worse the coverage of the terminal device is, the longer the length of the paging indicator sent by the network device is. For example, in order to satisfy the detection performance of the terminal device under the coverage level of 144dB/154dB/164dB, the network device needs to set the length of the paging indication signal to 1ms/8ms/70ms respectively. It can be seen that the signal length of the paging indicator signal required by the terminal device with the coverage level of 164dB is significantly larger than the signal length of the paging indicator signal required by the terminal device with better coverage. Here, as a way of measuring the coverage of the terminal device, the coverage level 144dB/154dB/164dB refers to the attenuation value of the signal received by the terminal device from the network device, and the larger the attenuation value is, the worse the coverage of the terminal device is. Namely, among 144dB/154dB/164dB, the coverage of the terminal equipment with the coverage level of 164dB is the worst.

However, when the network device transmits the paging indication signal, the network device needs to transmit at least one signal, i.e. the wake-up signal or the sleep signal, at the position where the wake-up signal/sleep signal appears, regardless of whether the terminal device needs to be paged. If the detection performance of the terminal device with poor coverage is to be satisfied and the signal length of the paging indicator signal is increased, the resource overhead of the network device for sending the paging indicator signal is correspondingly increased. In the foregoing example, considering a terminal device with a coverage level of 164dB, setting the length of the paging indicator signal to 70ms is a large network resource overhead. In addition, the increased resource overhead may affect the resource scheduling of other terminal devices, thereby affecting the system performance.

Therefore, the embodiment of the application can limit the applicability of the wake-up signal and the sleep signal to the terminal equipment with poor coverage by respectively setting the applicable coverage ranges for the wake-up signal and the sleep signal, thereby effectively saving network resources of the system and reducing the negative influence of the paging indication signal on the system.

Specifically, the network device may indicate the coverage of the wake-up signal and the sleep signal in various ways, for example, may indicate only the coverage of the sleep signal, may indicate only the coverage of the wake-up signal, or may indicate both the coverage of the sleep signal and the coverage of the wake-up signal.

In an implementation of step S501, the network device may send first coverage indication information to indicate a coverage of the sleep signal. The first coverage indication information may specifically include network parameters used for classifying or evaluating the coverage condition of the terminal device, such as a signal attenuation value, an RSRP value, a NPDCCH repetition reception number, and the like. Therefore, the network device can send out the dormancy signal only suitable for part of the terminal devices (namely, the terminal devices within the coverage range of the dormancy signal), and correspondingly, the terminal devices can detect the dormancy signal according to whether the terminal devices belong to the coverage range of the dormancy signal sent by the network device, so that the resource overhead of sending the dormancy signal by the network device is reduced, and the negative influence of the overlarge resource overhead of sending the dormancy signal on the scheduling of the terminal devices is avoided.

In one possible design, the first coverage indication information may be a first signal attenuation value. The smaller the attenuation value of the signal received from the network device, the better the coverage of the terminal device and vice versa. Therefore, according to the first signal attenuation value, the network device can set the terminal device receiving the signal from the network device with the attenuation value smaller than the first signal attenuation value to be within the coverage range of the sleep signal, and for the terminal device with the attenuation value greater than or equal to the first signal attenuation value, the coverage condition is considered to be poor, and the terminal device is excluded from the coverage range of the sleep signal, so that the sleep signal cannot be used.

It should be noted that, the size of the first signal attenuation value may be specifically set by those skilled in the art according to the actual requirement of the system performance, and the present application is not limited to this.

For example, the first signal attenuation value may be 164dB, such that end devices with coverage levels of 144dB and 154dB are within the coverage range of the sleep signal and can use the sleep signal, while end devices with a coverage level of 164dB are outside the coverage range of the sleep signal and cannot use the sleep signal.

The first signal attenuation value is given in the first coverage information, so that the sleep signal sent by the network device is only suitable for the terminal device with better coverage condition, and the technical problem that the resource overhead of the network device for sending the sleep signal is too large and the scheduling of other terminal devices is influenced due to the fact that the signal length of the paging indication signal is increased in order to meet the detection performance requirement of the terminal device with poorer coverage condition on the sleep signal is solved.

In one possible design, the first coverage indication information may also be a first power used to evaluate the quality of the coverage condition of the terminal device from the dimension of RSRP. The RSRP value of the terminal device represents the received strength of the signal sent by the network device, and the larger the RSRP value of the terminal device is, the larger the received strength of the signal is, and accordingly, the better the coverage condition is. Therefore, according to the first power, the network device may set the terminal device with RSRP greater than the first power to be within the coverage of the sleep signal, and regarding the terminal device with RSRP less than or equal to the first power, the coverage is considered to be too poor, and the terminal device is excluded from the coverage of the sleep signal, and the sleep signal is not usable.

It should be noted that, the first power can be specifically set by those skilled in the art according to the actual requirement of the system performance, and the present application is not limited to this.

By giving the first power in the first coverage information, the sleep signal sent by the network device can be only suitable for the terminal device with better coverage, so that the technical problem that the resource overhead of the network device for sending the sleep signal is too large and the scheduling of other terminal devices is influenced due to the fact that the signal length of the paging indication signal is increased in order to meet the detection performance requirement of the terminal device with poorer coverage on the sleep signal is solved.

In a possible design, the first coverage indication information may also be a first repetition number, in practical application, the network device may repeatedly send the same data to the terminal device for multiple times, and the terminal device performs repeated receiving for multiple times until the data sent by the network device is obtained through successful detection or correct decoding. In this example, the terminal device also records and stores the most recent number of repeated receptions. The terminal equipment with worse coverage condition has larger repeated receiving times, and the terminal equipment with better coverage condition has smaller repeated receiving times. Therefore, according to the first repetition number, the network device may set the terminal device that correctly receives the NPNCCH with the repetition reception number less than the first repetition number to be within the coverage of the sleep signal, and regarding the terminal device with the repetition reception number greater than or equal to the first repetition number, the coverage is considered to be too poor, and the terminal device is excluded from the coverage of the sleep signal, and the sleep signal cannot be used.

It should be noted that, the size of the first repetition number may be specifically set by a person skilled in the art according to actual requirements on system performance, and the present application is not limited to this specifically.

By giving the first repetition times in the first coverage information, the sleep signal sent by the network device can be only suitable for the terminal device with better coverage, so that the technical problem that the resource overhead of the network device for sending the sleep signal is too large and the scheduling of other terminal devices is influenced due to the fact that the signal length of the paging indication signal is increased in order to meet the detection performance requirement of the terminal device with poorer coverage on the sleep signal is solved.

It should be noted that, in this embodiment of the application, the terminal device may use the sleep signal means that the terminal device may normally detect the sleep signal and enter the sleep state during the next paging opportunity according to the indication of the sleep signal, and the terminal device may not use the sleep signal means that the terminal device does not detect the sleep signal, or after detecting the sleep signal, ignores or discards the sleep signal, and does not perform corresponding operations according to the indication of the sleep signal. If a certain terminal device is located in the coverage range of the sleep signal, it indicates that the terminal device can use the sleep signal, otherwise, it indicates that the terminal device cannot use the sleep signal. And whether the terminal device can use the wake-up signal is similar.

In a specific implementation of step S501, the network device may further send second coverage indication information to indicate a coverage of the wake-up signal. Similar to the first coverage indication information, the second coverage indication information may also specifically include network parameters used for classifying or evaluating the coverage condition of the terminal device, such as a signal attenuation value, an RSRP value, and the number of repeated receptions; in addition, in the embodiment of the present application, the second coverage indication information and the first coverage indication information may include network parameters of the same type or different types, which is not limited in this application. Optionally, in a scenario where the network device indicates both the coverage of the sleep signal and the coverage of the wake-up signal, the network device sets the types of the network parameters included in the first coverage indication information and the second coverage indication information to be the same.

Therefore, the network device can send out the wake-up signal only suitable for part of the terminal devices (namely, the terminal devices within the coverage range of the wake-up signal), and accordingly, the terminal devices can detect the wake-up signal according to whether the terminal devices belong to the coverage range of the wake-up signal, so that the resource overhead of the network device for sending the wake-up signal is effectively reduced, and the negative influence of the overlarge resource overhead of the network device for sending the wake-up signal on the scheduling of the terminal devices is avoided.

In one possible design, the second coverage indication information may be a second signal attenuation value, according to which the network device may set the terminal device receiving the signal from the network device with an attenuation value smaller than the second signal attenuation value to be within the coverage of the wake-up signal, and regarding the terminal device with an attenuation value greater than or equal to the second signal attenuation value, the coverage is considered to be too poor and excluded from the coverage of the wake-up signal, so that the wake-up signal is not available.

It should be noted that, the size of the second signal attenuation value can be specifically set by those skilled in the art according to the actual requirement of the system performance, and the present application is not limited to this.

Similar to the manner of indicating the coverage of the sleep signal, the wake-up signal sent by the network device can only be used for the terminal device with better coverage by giving the second signal attenuation value, so that the technical problem that the resource overhead of the network device for sending the wake-up signal is too large and the scheduling of other terminal devices is influenced due to the increase of the signal length of the paging indication signal in order to meet the detection performance requirement of the terminal device with poorer coverage on the wake-up signal is solved.

If the network device indicates the coverage areas suitable for the sleep signal and the wake-up signal, optionally, the coverage area set by the network device for the sleep signal may be different from the coverage area set for the wake-up signal, that is, if the first coverage indication information and the second coverage indication information are both signal attenuation values, the first signal attenuation value is not equal to the second signal attenuation value. Further, the network device may set the first signal attenuation value to be less than the second signal attenuation value. In this way, according to the set first signal attenuation value and the second signal attenuation value, the network device roughly divides the terminal device into three categories according to the coverage condition of the terminal device, wherein the first category is the terminal device with the attenuation value smaller than the first signal attenuation value, the coverage condition of the terminal device is the best among the three categories of terminal devices, the terminal devices are located in the coverage range of the sleep signal and the wake-up signal, and the sleep signal and the wake-up signal can be used simultaneously; the second type is terminal equipment with an attenuation value greater than or equal to the first signal attenuation value but smaller than the second signal attenuation value, the coverage condition of the terminal equipment is second best or common in the three types of terminal equipment, and the terminal equipment is positioned in the coverage range of the wake-up signal but not in the coverage range of the sleep signal, so that only the wake-up signal can be used, and the sleep signal cannot be used; the third type is a terminal device with an attenuation value larger than the second signal attenuation value, and the terminal device has the worst coverage condition in the three types of terminal devices, and the terminal devices do not belong to the coverage range of the sleep signal or the coverage range of the wake-up signal, so that the sleep signal and the wake-up signal cannot be used.

Optionally, the second coverage indication information may also be a second power, where the second power is used to evaluate the quality of the coverage condition of the terminal device from the dimension of RSRP, and the larger the RSRP value of the terminal device, the larger the reception strength of the signal sent by the network device, and accordingly, the better the coverage condition. Therefore, according to the second power, the network device may set the terminal device with RSRP greater than the second power to be within the coverage of the wake-up signal, and regarding the terminal device with RSRP less than or equal to the second power, the coverage is considered to be too poor, and the terminal device is excluded from the coverage of the wake-up signal, and the wake-up signal cannot be used.

It should be noted that, the second power can be specifically set by those skilled in the art according to the actual requirement of the system performance, and the present application is not limited to this.

The second power is given in the second coverage information, so that the wake-up signal sent by the network device is only applicable to the terminal device with better coverage, and the technical problem that the resource overhead of the network device for sending the wake-up signal is too large and the scheduling of other terminal devices is influenced due to the increase of the signal length of the paging indication signal in order to meet the detection performance requirement of the terminal device with poorer coverage on the wake-up signal is solved.

If the network device indicates the coverage areas suitable for the sleep signal and the wake-up signal, optionally, the coverage area set by the network device for the sleep signal may be different from the coverage area set for the wake-up signal, that is, if the first coverage indication information and the second coverage indication information are both power values, the values of the first power and the second power are not equal.

Further, the network device may set the first power to be greater than the second power. Thus, according to the set first power and second power, the network device roughly divides the terminal devices into three categories according to the coverage conditions of the terminal devices, wherein the first category is the terminal devices with the RSRP larger than the first power, the coverage conditions of the terminal devices are best, the terminal devices are located in the coverage range of both the sleep signal and the wake-up signal, and the sleep signal and the wake-up signal can be used simultaneously; the second type is terminal equipment with RSRP less than or equal to the first power but greater than the second power, the coverage condition of the terminal equipment is second best or general, the terminal equipment is positioned in the coverage range of the wake-up signal but not in the coverage range of the sleep signal, so that only the wake-up signal can be used, but not the sleep signal; the third category is terminal devices with RSRP less than the second power, which are the worst coverage, and they do not belong to the coverage of either sleep signal or wake-up signal, so sleep and wake-up signals are not available.

It can be seen that if the first power is greater than the second power, the coverage of the wake-up signal is larger than that of the sleep signal, and the wake-up signal can cover the terminal device with smaller RSRP. There may be some terminal devices with poor coverage that do not belong to the coverage area of the sleep signal and cannot use the sleep signal, but may use the wake-up signal because their RSRP is still greater than the second power and is within the coverage area of the wake-up signal.

Optionally, the second coverage indication information may also be a second repetition number, where the second repetition number is used to evaluate the coverage condition of the terminal device according to the dimension of the repeated receiving times when the terminal correctly receives the NPDCCH sent by the network device. The smaller the number of repeated receptions is, the better the coverage is, whereas the larger the number of repeated receptions is, the worse the coverage is. Therefore, according to the second repetition number, the network device may set the terminal device that correctly receives the NPDCCH sent by the network device and has the repeated reception number less than the second repeated reception number to be within the coverage of the wake-up signal, and for the terminal device that has the repeated reception number greater than or equal to the second repeated reception number, the coverage is considered to be poor, and the terminal device is excluded from the coverage of the wake-up signal and cannot use the wake-up signal.

It should be noted that, the size of the second repetition number can be specifically set by those skilled in the art according to the actual requirement of the system performance, and the present application is not limited to this.

The second number of repetitions is given in the second coverage information, so that the wake-up signal sent by the network device is only applicable to the terminal device with a better coverage condition, and the technical problem that the resource overhead of the network device for sending the wake-up signal is too large and the scheduling of other terminal devices is influenced due to the increase of the signal length of the paging indicator signal in order to meet the detection performance requirement of the terminal device with a poorer coverage condition on the wake-up signal is solved.

In this embodiment of the application, if the network device indicates the coverage areas applicable to both the sleep signal and the wake-up signal, but the coverage areas are different, and both the first coverage indication information and the second coverage indication information are the number of repetitions, the first number of repetitions is different from the second number of repetitions. Further, the network device may set the first repetition number to be less than the second repetition number. Thus, according to the set first repetition frequency and the second repetition frequency, the network device roughly divides the terminal device into three categories according to the coverage condition of the terminal device, wherein the first category is the terminal device with the repeated receiving frequency of the NPDCCH being smaller than the first repetition frequency, the coverage condition of the terminal device is the best among the three categories of terminal devices, the terminal devices are located in the coverage range of the sleep signal and the wake-up signal, and the sleep signal and the wake-up signal can be used simultaneously; the second type is terminal equipment with the repeated receiving times of the NPDCCH being more than or equal to the first repeated times but less than the second repeated times, the coverage condition of the terminal equipment is second good or common in the three types of terminal equipment, and the terminal equipment is positioned in the coverage range of the wake-up signal but not in the coverage range of the sleep signal, so that only the wake-up signal can be used, but the sleep signal cannot be used; the third type is terminal equipment with the repeated receiving times of the NPDCCH being greater than the second repeated times, and the terminal equipment of the type has the worst coverage condition among the three types of terminal equipment, and the terminal equipment does not belong to the coverage range of the sleep signal or the coverage range of the wake-up signal, so that the sleep signal and the wake-up signal cannot be used.

It can be seen that if the first power is greater than the second power, the coverage of the wake-up signal indicated by the second repetition number is larger than that of the sleep signal, and the terminal device with the larger NPDCCH repeated reception number can be covered. There may be some terminal devices with poor coverage that do not belong to the coverage of the sleep signal and cannot use the sleep signal, but the terminal devices may use the wake-up signal because the NPDCCH of the terminal devices is received repeatedly less than the second repetition number and is within the coverage of the wake-up signal.

It should be noted that, in this embodiment of the application, the terminal device may use the sleep signal means that the terminal device may normally detect the sleep signal and enter the sleep state during the next paging opportunity according to the indication of the sleep signal, and the terminal device may not use the sleep signal means that the terminal device does not detect the sleep signal, or does not perform corresponding operation according to the indication of the sleep signal after detecting the sleep signal. If a certain terminal device is located in the coverage range of the sleep signal, it indicates that the terminal device can use the sleep signal, otherwise, it indicates that the terminal device cannot use the sleep signal. And whether the terminal device can use the wake-up signal is similar.

In the specific implementation of step S502, the terminal device may receive first coverage indication information sent by the network device, and determine a coverage area of the sleep signal according to the first coverage indication information;

and receiving second coverage indication information sent by the network equipment, and determining the coverage range of the wake-up signal according to the second coverage indication information.

In the specific implementation of step S503, the terminal may detect a signal sent by the network device, and specifically may detect the sleep signal according to whether the terminal is located within the coverage of the sleep signal; and detecting the wake-up signal according to whether the wake-up signal is within the coverage range of the wake-up signal.

Optionally, the terminal detects the signal sent by the network device if the first coverage indication information is the first signal attenuation value, and if it is determined that the attenuation value of the signal received by the terminal device from the network device is greater than the first signal attenuation value, the terminal device may determine that the terminal device is located outside the coverage range of the sleep signal, and ignore the sleep signal, otherwise, the terminal device detects the sleep signal based on the first detection window length determined in step S304.

Fig. 6 is a schematic diagram of the terminal device detecting the signal sent by the network device in this example, and as shown in fig. 6, the terminal device with a coverage level of 144dB/154dB is located in the coverage of the sleep signal, and the terminal device with a coverage level of 164dB is located outside the coverage of the sleep signal.

The 144dB/154dB terminal device detects the paging indicator signal at the wake-up signal/sleep signal position according to the wake-up signal/sleep signal assumption, namely, detects the sleep signal based on the first detection window length and detects the wake-up signal based on the second detection window length. And the 164dB terminal equipment is at the position of the wake-up signal/sleep signal, the paging indication signal is detected according to the hypothesis of wake-up signal/discontinuous transmission, namely, the wake-up signal is detected only based on the length of the second detection window, and the sleep signal is ignored.

The terminal device of 144dB/154dB/164dB detects the paging indication signal at the wake-up signal/discontinuous transmission location according to the wake-up signal/discontinuous transmission assumption as usual.

Optionally, if the first coverage indication information is the first power, in subsequent step S503, the terminal detects a signal sent by the network device, and if it is determined that the reference signal received power RSRP of the terminal device is smaller than the first power, the terminal device may determine that the terminal device is located outside the coverage of the sleep signal, and ignore the sleep signal at the wake-up signal/sleep signal position, otherwise, detect the sleep signal based on the first detection window length determined in step S304.

Optionally, if the first coverage indication information is the first repetition number, in subsequent step S503, the terminal detects a signal sent by the network device, and if it is determined that the number of repeated receptions of the NPDCCH correctly received by the terminal device is greater than the first repetition number, the terminal device may determine that the terminal device is located outside the coverage of the sleep signal, ignore the sleep signal at the wake-up signal/sleep signal position, otherwise, detect the sleep signal based on the first detection window length determined in step S304.

It should be noted that, in this embodiment of the application, the terminal device ignores the sleep signal, where the terminal device does not detect the sleep signal or discards the detected sleep signal when determining that the terminal device is located outside the coverage of the sleep signal, or does not perform the setting operation according to the instruction of the sleep signal after detecting the sleep signal.

In a possible design, the second coverage indication information is a second signal attenuation value, the terminal detects the signal sent by the network device, and if it is determined that the attenuation value of the signal received by the terminal device from the network device is greater than the second signal attenuation value, the terminal device may determine that the terminal device is located outside the coverage range of the wake-up signal, and ignores the wake-up signal, otherwise, the terminal device detects the wake-up signal based on the second detection window length determined in step S304.

Optionally, if the first coverage indication information is the second power, the terminal detects a signal sent by the network device, if it is determined that the reference signal received power RSRP of the terminal device is less than the second power, the terminal device may determine that the terminal device is located outside the coverage range of the wake-up signal, and ignore the wake-up signal, otherwise, the terminal device detects the wake-up signal based on the second detection window length determined in step S304.

Optionally, if the first coverage indication information is the second repetition number, the terminal detects a signal sent by the network device, if it is determined that the number of repeated receptions of the NPDCCH correctly received by the terminal device is greater than the second repetition number, the terminal device may determine that the terminal device is located outside the coverage range of the wake-up signal, and ignore the wake-up signal, otherwise, the terminal device detects the wake-up signal based on the second detection window length determined in step S304.

Based on the three possible implementation manners, if the terminal device determines that the terminal device is located in the coverage range of the wake-up signal, the terminal device detects the wake-up signal. If the terminal device successfully detects the wake-up signal, it is determined that the terminal device needs to wake up in the subsequent paging opportunity period, and monitors the NPDCCH. If the terminal device monitors the NPDCCH in the period of the pager, the terminal device needs to further judge whether the network device pages the terminal device, if the terminal device confirms that the terminal device is paged, the terminal device enters a connection state to prepare for service data interaction with the network device, and if the terminal device does not confirm that the terminal device is paged, the terminal device continues to be in a dormant state.

It should be noted that, in this embodiment of the application, the terminal device ignores the wake-up signal may be that, when determining that the terminal device is located outside the coverage of the wake-up signal, the terminal device does not detect the wake-up signal, or discards the detected wake-up signal, or does not perform a setting operation according to an instruction of the wake-up signal after detecting the wake-up signal, for example, does not monitor the NPDCCH during a subsequent paging opportunity.

In addition, in this embodiment, the network device may send the first coverage indication information and/or the second coverage indication information by sending a broadcast signaling. If the network device sends both the first coverage indication information and the second coverage indication information, the network device sends the first coverage indication information and the second coverage indication information through the same broadcast signaling, or sends the first coverage indication information and the second coverage indication information through different broadcast signaling, which is not limited in this application.

The embodiment of the present application further does not specifically limit the order in which the network device sends the first indication information and the second indication information, and sends the first coverage indication information and the second coverage indication information, as long as it is ensured that the terminal device receives the first indication information, the second indication information, the first coverage indication information, and the second coverage indication information sent by the network device before step S503.

Further, in this embodiment of the present application, the network device may further activate, by broadcasting or sending a dedicated signaling, limitation of the sleep signal on the coverage of the terminal device, so that the sleep signal is only applicable to the terminal devices located in the coverage of the network device.

Specifically, the network device may send first activation indication information, where the first activation indication information is used to indicate whether the terminal device determines, according to the first coverage indication information, whether the terminal device is located within a coverage area of the sleep signal indicated by the first coverage indication information.

That is, the network device may trigger whether the terminal device determines whether itself is located in the coverage of the sleep signal indicated by the first coverage indication information according to the first coverage indication information by broadcasting or sending a dedicated signaling. Although the network device has set the coverage for the sleep signal through the first coverage indication information, the network device does not enable the coverage set for the sleep signal until the network device transmits the first activation indication information. At this time, all terminal devices accessing the cell can use the sleep signal sent by the network device regardless of the coverage of the terminal device. Once the network device sends the first activation indication information, the network device indicates that the network device starts a coverage range set for the sleep signal, the network device limits the applicability of the sleep signal to the terminal device located in the coverage range of the sleep signal according to the coverage condition of each terminal device accessing the cell, and accordingly, the terminal device can detect the sleep signal according to whether the terminal device is located in the coverage range of the sleep signal, so that the resource overhead of the network device for sending the sleep signal can be reduced, and the negative influence of the excessive resource overhead of the network device for sending the sleep signal on the system can be avoided.

Similarly, the network device may also activate the limitation of the coverage of the terminal device by the wake-up signal by broadcasting or sending dedicated signaling, so that the wake-up signal is only applicable to the terminal devices within its coverage.

In one possible design, the network device may send second activation indication information, where the second activation indication information is used to indicate whether the terminal device determines whether the terminal device is located in the coverage of the wake-up signal indicated by the second coverage indication information according to the second coverage indication information.

That is, the network device may also trigger whether the terminal device determines whether itself is located in the coverage of the wake-up signal indicated by the second coverage indication information according to the second coverage indication information by broadcasting or sending a dedicated signaling. Similar to the principle that the network device sends the first activation indication information, although the network device has set a coverage for the wake-up signal, the network device does not enable the coverage set for the wake-up signal before the network device sends the second activation indication information. At this time, all terminal devices accessing the cell can use the wake-up signal sent by the network device, regardless of the coverage of the terminal device. Once the network device sends the second activation indication information, the network device indicates that the network device starts a coverage set for the wake-up signal, the network device limits the applicability of the wake-up signal to the terminal device located in the coverage of the wake-up signal according to the coverage of each terminal device accessing the cell, and accordingly, the terminal device can detect the wake-up signal according to whether the terminal device is located in the coverage of the wake-up signal, so that the resource overhead of sending the wake-up signal by the network device can be reduced, and the negative influence of the excessive resource overhead of sending the wake-up signal on the system can be avoided.

It should be noted that, in this embodiment of the application, the network device may send the first activation indication information and/or the second activation indication information through a system message, for example, the first activation indication information may be 1 bit set in a position in the system message, if the position is 1, it indicates that the network device has sent the first activation indication information, and if the position is 0, it indicates that the network device has not sent the first activation indication information. The second activation indication information is similar, and details are not repeated herein.

Based on the message sending method in steps S301 to S304, the present application also provides another specific embodiment of the message sending method.

In this embodiment, the network device may further give a maximum duration and a minimum duration of the paging indicator signal, and according to the maximum duration and the minimum duration, the terminal device may determine whether it is able to perform cell synchronization by the paging indicator signal. This embodiment will be described in detail below.

Fig. 7 is a schematic flow chart of a signal sending method according to this embodiment.

Referring to fig. 7, the method further includes:

step S701: the network equipment generates first duration indication information and second duration indication information;

Step S702: the network equipment sends first duration indication information and second duration indication information;

step S703: the terminal equipment receives first duration indication information and second duration indication information sent by the network equipment;

step S704: the terminal equipment determines the maximum duration of the wake-up signal according to the first duration indication information; determining the minimum duration of the wake-up signal according to the second duration indication information;

step S705: and the terminal equipment determines whether the cell synchronization can be carried out through the wake-up signal according to the minimum duration and/or the maximum duration of the wake-up signal.

In the prior art, the network device instructs the terminal device about the maximum signal length and location of the paging indicator signal in order for the terminal device to detect the signal. The actual transmission length of the paging indicator signal may be less than or equal to the configured maximum signal length, but the network device does not indicate the actual transmission length of the paging indicator signal. Therefore, the terminal device can only know the maximum signal length of the wake-up signal or the sleep signal, but not the actual transmission length thereof. For a terminal device which needs to synchronize with a wake-up signal or a sleep signal, the problem of power consumption waste exists at this time. For example, the terminal device may assume that the actual transmission length of the wake-up signal or sleep signal is sufficient for synchronization, based on which synchronization is made with the wake-up signal or sleep signal, but the actual transmission length of the wake-up signal or sleep signal may be short and insufficient for synchronization, resulting in inefficient attempts by the terminal device and wasted power consumption.

As shown in fig. 8, in order to solve the problem, in this embodiment of the present application, the network device may further configure and instruct the terminal device to obtain the maximum signal transmission length and the minimum signal transmission length of the paging indication signal, and ensure that the actual transmission length of the paging indication signal is not less than the configured minimum signal transmission length.

Specifically, in the specific implementation of step S701, the first duration indication information generated by the network device is used to instruct the terminal device to determine the maximum duration of the wake-up signal, where the maximum duration may be the maximum signal transmission length configured for the wake-up signal by the network device (i.e., configured maximum duration of WUS), and an actual signal length of the wake-up signal transmitted by the network device is always less than or equal to the maximum duration, and it should be noted that the maximum duration may be less than or equal to the second detection window length.

The second duration indication information generated by the network device is used to indicate the terminal device to determine the minimum duration of the wake-up signal, where the minimum duration may be a minimum signal transmission length (i.e., a configured minimum duration of WUS) configured for the wake-up signal by the network device, and an actual signal length of the wake-up signal transmitted by the network device is always greater than or equal to the minimum duration.

Optionally, the first duration indication information may be the maximum duration, and the second duration indication information may be the minimum duration.

Optionally, the first duration indication information may be the maximum duration, and the second duration indication information may be a ratio or a difference between the minimum duration and the maximum duration; or, the first duration indication information is a ratio or a difference between the maximum duration and the minimum duration, and the second duration indication information is the minimum duration.

Optionally, the first duration indication information may be a ratio of the maximum duration to a set repetition number, and the second duration indication information may be a ratio of the minimum duration to the set repetition number, where the set repetition number is a maximum repetition number of the PDCCH during a paging opportunity.

Optionally, the first duration indication information is a ratio of the maximum duration to a set repetition number, and the second duration indication information is a ratio or a difference between the minimum duration and the maximum duration; or, the first duration indication information is a ratio or a difference between the maximum duration and the minimum duration, and the second duration indication information is a ratio between the minimum duration and the set repetition number; wherein the set repetition number is a maximum repetition number of the PDCCH during a paging opportunity.

In a specific implementation of step S702, the network device may send the first duration indication information and the second duration indication information through a broadcast signaling, and the network device may send the first duration indication information and the second duration indication information through the same broadcast signaling or send the first duration indication information and the second duration indication information through different broadcast signaling, which is not limited in this application.

In the specific implementation of step S703 to step S704, the terminal device receives the first duration indication information and the second duration indication information sent by the network device, and may determine the maximum duration of the wake-up signal according to the first duration indication information; and determining the minimum duration of the wake-up signal according to the second duration indication information.

The terminal device may determine the maximum duration and the minimum duration of the wake-up signal in various ways according to the difference between the information given by the network device in the first duration indication information and the second duration indication information. Specifically, reference may be made to the determination method of the first detection window length and the second detection window length described above in this application, which is not described herein again.

In a specific implementation of step S705, the terminal device may determine whether it is able to perform cell synchronization by using the wake-up signal according to the minimum duration and/or the maximum duration of the wake-up signal.

Specifically, if it is determined that the signal length required for cell synchronization is less than the minimum duration, the terminal device determines that cell synchronization can be performed through the wake-up signal; alternatively, the first and second electrodes may be,

In this embodiment, the network device may further generate third duration indication information and fourth duration indication information, where the third duration indication information is used to indicate the terminal device to determine the maximum duration of the sleep signal, and the fourth duration indication information is used to indicate the terminal device to determine the minimum duration of the sleep signal;

the network device sends the third duration indication information and the fourth duration indication information. Therefore, the terminal device can acquire the maximum duration and the minimum duration of the sleep signal after receiving the third duration indication information and the fourth duration indication information, so that whether cell synchronization can be performed through the sleep signal can be further judged, and the technical problems that in the prior art, the terminal device only acquires the maximum signal length of the paging indication signal and tries to perform cell synchronization through the sleep signal under the scene that the actual transmission length of the paging indication signal is not known, but the actual transmission length of the sleep signal is not enough to perform cell synchronization and waste power consumption are solved.

In a possible implementation manner, the network device may further generate first duration indication information, third duration indication information, and fourth duration indication information, and transmit the first duration indication information, the third duration indication information, and the fourth duration indication information. The first duration indication information is used for indicating the terminal equipment to determine the maximum duration of the wake-up signal, the third duration indication information is used for indicating the terminal equipment to determine the maximum duration of the sleep signal, and the fourth duration indication information is used for indicating the terminal equipment to determine the minimum duration of the sleep signal;

Therefore, after receiving the first duration indication information, the third duration indication information and the fourth duration indication information, the terminal device can determine whether cell synchronization can be performed through the paging indication signal according to the determined maximum duration of the wake-up signal, the determined maximum duration of the sleep signal and the determined minimum duration of the sleep signal. The principle is as above, and is not described in detail here. After acquiring the minimum signal transmission length of the paging indication signal, the terminal equipment can more accurately judge whether the WUS signal or the GTS signal can be used for synchronization: if the terminal equipment considers that the minimum signal transmission length of the paging indication signal is enough for synchronization, the terminal equipment uses the WUS signal or the GTS signal for synchronization; on the contrary, if the terminal device considers that the minimum signal transmission length of the paging indication signal is not sufficient for synchronization, the terminal device may not attempt synchronization using the WUS signal or the GTS signal, thus avoiding invalid attempts and saving power consumption of the terminal device.

Fig. 11 is a schematic structural diagram illustrating a network device provided in an embodiment of the present application, where the network device is applicable to the system shown in fig. 2, and may be used to implement the method or steps of the foregoing method embodiment. As shown in fig. 11, the network device 1100 may include one or more Remote Radio Units (RRUs) 1101 and one or more baseband units (BBUs) 1102.

The control circuit 1202 is mainly used for converting baseband signals and radio frequency signals and processing radio frequency signals. The control circuit 1202 and the antenna 1201, together also referred to as a transceiver, are primarily intended for transceiving radio frequency signals in the form of electromagnetic waves. Input and output devices, such as touch screens, display screens or keyboards, are used primarily for receiving data input by a user and for outputting data to the user.

When the terminal device is powered on, the processor 1203 may read the software program in the memory, interpret and execute the instructions of the software program, and process the data of the software program.
