Description

A signal transmission method, network device and terminal device

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 technique

In a wireless communication system, a network device periodically sends a paging signal to indicate whether a terminal device should switch from an idle state to a connected state, so as to exchange service data with the terminal device. A terminal device in an idle state periodically wakes up to detect a paging signal, the period of which is periodically woken up is called a discontinuous reception (DRX) period, and the wake-up position is called a paging occasion (PO). The terminal will detect the physical downlink control channel (PDCCH) in the search space starting from the PO position to determine whether it is being paged by the network device, and if it is paged, it will enter the connected state.

In a narrow band internet of things (NB-IoT) system, a network device is provided with a paging indication signal before the PO location to indicate whether the terminal device needs to wake up at the PO location. Fig. 1 shows the manner in which a network device sends a paging indication signal in the prior art. A wake up signal (WUS)/goto sleep signal (GTS) periodically appears before some POs, while WUS/ Discontinuous transmission (DTX) occurs before the remaining POs. The network equipment indicates the maximum signal length and position of the paging indication signal to the terminal equipment, so that the terminal equipment can detect the signal.

At the WUS/GTS position, if the terminal detects a WUS signal or a GTS signal during the maximum signal length period, it will perform corresponding processing. Only then does it think that it has moved out of the cell, and then triggers operations such as cell measurement and reselection. Since the maximum signal length indicated by the network device is usually larger than the actual signal length of the WUS signal and the GTS signal, the larger the maximum signal length indicated by the network device, the longer the time for the terminal to detect the signal, and the greater the power consumption. Especially in actual scenarios, the actual signal lengths of WUS signals and GTS signals are different, and there are many cases in which network devices send GTS signals. Indicating a unified maximum signal length for WUS signals and GTS signals will significantly increase the terminal detection of GTS signals. power consumption when.

Therefore, there is an urgent need for a signal transmission method, which is used to solve the technical problem in the prior art that the terminal consumes a large amount of power when detecting the paging indication signal.

SUMMARY OF THE INVENTION

The purpose of the embodiments of the present application is to provide a signal sending method, a network device and a terminal device, so as to reduce the 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 network device generates first indication information and second indication information, where the first indication information is used to instruct the terminal device to determine the length of the first detection window of the sleep signal, and the second indication information is used to instruct the terminal device to determine the wake-up signal the second detection window length of the PDCCH;

In this embodiment of the present application, the network device may generate two pieces of indication information, where the first indication information is used to instruct the terminal device to determine the length of the first detection window of the sleep signal, and the second indication information is used to instruct the terminal device to determine the second length of the wake-up signal. The length of the detection window, therefore, after the network device sends the first indication information and the second indication information, the terminal device can determine the length of the first detection window according to the first indication information, and determine the length of the second detection window according to the second indication information, and then determine the length of the second detection window according to the second indication information. The sleep signal is detected within the length of the first detection window, and the wake-up signal is detected within the length of the second detection window, thereby avoiding that the network device in the prior art only configures the maximum signal length of the paging indication signal, regardless of whether the network device sends a sleep signal or a wake-up signal, Terminal devices all need to detect signals within the maximum signal length, which leads to a technical problem of high power consumption.

In a possible design, the length of the first detection window is smaller than the length of the second detection window.

Considering that in practical applications, the probability of the network device paging the terminal device or the system message change may be relatively low, so the network device may not send the PDCCH during most of the paging opportunities, that is, the network device sends the PDCCH at the position of the wake-up signal/sleep signal. The probability of the dormant signal is higher, and the probability that the network device does not send any signal at the wake-up signal/discontinuous sending position is relatively high. The resource overhead of the network device for sending the sleep signal is effectively reduced, and the power consumption of the terminal device for detecting the sleep signal is reduced.

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 the ratio or difference between the length of the second detection window and the length of the first detection window; or,

The first indication information is the ratio or 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.

In this way, the network device may clearly indicate the respective detection window lengths of the sleep signal and the wake-up signal in both the first indication information and the second indication information, or may only indicate the search window corresponding to the indication information in plaintext in one of the indication information. Call the detection window length of the indication signal, and indicate the ratio or difference between the lengths of the two detection windows in another indication message. The ratio or difference between them is used to determine another detection window length, thereby effectively improving the flexibility of the network device configuration indication information.

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

Optionally, the first indication information is the ratio of the length of the first detection window to the set number of repetitions, and the second indication information is the ratio of the length of the second detection window to the length of the first detection window or the difference; or,

In this embodiment of the present application, the network device may further expand the manner in which the network device configures the indication information based on the maximum number of repetitions of the PDCCH during the paging opportunity, thereby effectively improving the flexibility of the network device configuration indication information.

In a possible design, the network device may send first coverage indication information, where the first coverage indication information is used to indicate the coverage of the sleep signal.

In this embodiment of the present application, the network device indicates the coverage range of the dormant signal by sending the first coverage indication information. In this way, the network device can send a dormancy signal that is only applicable to some terminal devices (that is, the terminal devices located within the coverage of the dormant signal). Accordingly, the terminal device can detect the dormant signal according to whether it belongs to the coverage of the dormant signal, thereby The resource overhead of sending the sleep signal by the network device is effectively reduced, and the negative impact of the excessive resource overhead of sending the sleep signal on the terminal device is avoided.

In this embodiment of the present application, the network device may indicate the coverage of the dormant signal by giving the first signal attenuation value. Since the attenuation value of the signal sent by the network device received by the terminal device can be used to measure the coverage of the terminal device, the smaller the signal attenuation value, the better the coverage of the terminal device. Therefore, in this embodiment of the present application, the attenuation of the signal received from the network device will be The terminal device whose value is less than the first signal attenuation value is set to be located within the coverage of the dormant signal, so that the dormant signal sent by the network device is only applicable to the terminal device with better coverage, thereby avoiding the need to meet the needs of the terminal device with poor coverage.

Since the RSRP of the terminal device represents the reception strength of the signal sent by the network device, it can also be used to measure the coverage of the terminal device. The larger the RSRP, the better the coverage of the terminal device. Therefore, in the embodiment of the present application, the terminal equipment whose RSRP is greater than the first power is set to be located within the coverage of the dormant signal, which can also achieve the purpose of making the dormant signal sent by the network device only applicable to the terminal device with better coverage, thereby avoiding the need for The technical problem of meeting the detection performance requirements of terminal devices with poor coverage for dormant signals results in excessive resource overhead of network devices sending dormant signals, which affects the scheduling of other terminal devices.

Since the number of repeated receptions that the terminal device correctly receives the PDCCH can also be used to measure the coverage of the terminal device, the smaller the number of repeated receptions, the better the coverage of the terminal device. Therefore, in the embodiment of the present application, the terminal equipment whose number of repeated receptions is less than the first number of repetitions is set to be located within the coverage of the dormant signal, which can also achieve the purpose of making the dormant signal sent by the network device only applicable to the terminal device with better coverage, Therefore, in order to meet the detection performance requirements of the terminal equipment with poor coverage for the sleep signal, the resource overhead of sending the sleep signal by the network equipment is too large, and the technical problem of affecting the scheduling of other terminal equipment is avoided.

For example, attenuation values are used to indicate. Further, the second signal attenuation value used to indicate the coverage of the wake-up signal may be greater than the first attenuation value. In this example, compared with the sleep signal, the coverage area of the wake-up signal is larger, and it can cover the terminal equipment with a larger signal attenuation value. There may be some terminal devices with poor coverage that do not belong to the coverage of the dormant signal and do not use the dormant signal. However, 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, so A wake-up signal can be used.

In this embodiment of the present application, if the network device indicates both the coverage of the sleep signal and the coverage of the wake-up signal, the network device may use the same type of network parameters to indicate the coverage of the sleep signal and the wake-up signal. For example, the power value is used to indicate. Further, the second power for indicating the coverage of the wake-up signal may be related to the first power for indicating the sleep signal, for example, the second power may be a certain power value smaller than the first power. In this scenario, compared to the sleep signal, the coverage area of the wake-up signal is larger, which can cover the terminal equipment with smaller RSRP. 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.

It should be noted that the solutions in the embodiments of the present application can also be applied to other wireless communication networks, and the corresponding names can also be Substitute with the name of the corresponding function in the other wireless communication network.

With reference to the above description, as shown in FIG. 3 , a schematic flowchart of a signal sending method provided by an embodiment of the present application is shown.

Referring to Figure 3, the method includes:

Step S301: the network device generates first indication information and second indication information;

Step S302: the network device sends the first indication information and the second indication information;

Step S303: the terminal device receives the first indication information and the second indication information sent by the network device;

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

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

It should be noted that the PDCCH described in the embodiments of the present application includes but is not limited to: a narrowband physical downlink control channel (narrowband downlink control channel, NPDCCH), a machine-type communication physical downlink control channel (machine-type communication physical downlink control channel, MPDCCH), enhanced physical downlink control channel (enhanced physical downlink control channel, ePDCCH). For the sake of simplicity, the following description will take the NPDCCH as an example.

The network device can also use the wake-up signal/sleep signal and the wake-up signal/discontinuous sending two signal transmission types at the same time to send the paging indication signal. Continuous transmission occurs before other paging opportunities, and the repetition period of the wake-up signal/sleep signal is an integer multiple of the discontinuous reception period. The terminal equipment can use the repeated wake-up signal/sleep signal for cell synchronization and confirmation. At the position where the wake-up signal/sleep signal appears, if there is NPDCCH in the subsequent paging opportunities (for example, the network device needs to page the terminal device or the system message has changed), the network device can send the wake-up signal at this position, otherwise send sleep signal. At the position where the wake-up signal/discontinuous transmission occurs, if there is an NPDCCH in a subsequent paging opportunity, the network device can send the wake-up signal at this position, otherwise no signal is sent.

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

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

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

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

In this way, when the terminal equipment detects the paging indication signal, if the corresponding paging indication signal is detected within the smaller detection window length, it does not need to continue to detect the signal within the larger detection window length, which can effectively reduce the terminal equipment. Detect the power consumption of the paging indication signal, so as to avoid that the network device in the prior art only configures the maximum signal length of the paging indication signal. Regardless of whether the network device sends a sleep signal or a wake-up signal, the terminal device needs to detect within the maximum signal length. signal, resulting in technical problems with large power consumption.

In a possible design, the length of the first detection window configured by the network device is smaller than the length of the second detection window. In practical applications, the probability of the network device paging the terminal device or the change of the system message may be relatively low, so the network device may not send the NPDCCH during most of the paging opportunities, that is, at the position of the wake-up signal/sleep signal, the network device sends the dormancy signal. The probability of the signal is higher, and the probability of the network device not sending any signal is higher at the wake-up signal/discontinuous transmission position. Considering that the actual signal length of the sleep signal may be smaller than the actual signal length of the wake-up signal, therefore, 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 for the network device to send the sleep signal. , and reduce the power consumption of the terminal device to detect the sleep signal.

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

In another possible design, the network device may only expressly indicate the length of the detection window corresponding to the indication information in one of the indication information, and indicate in the other indication information that the length of the other detection window is the same as that of the previous detection window. The ratio or difference of the lengths, so that the terminal device can determine the length of another detection window according to the length of the detection window indicated in plain text and the ratio or difference of the lengths of the two detection windows. For example, the network device may set the first indication information as the length of the first detection window, and set the second indication information as the ratio or difference between the length of the second detection window and the length of the first detection window, and the terminal device receives the first indication information and the second indication information, the length of the first detection window, the ratio of the length of the second detection window and the length of the first detection window can be multiplied, and the product can be determined as the length of the second detection window, or the length of the first detection window can be , and the sum of the difference between the length of the second detection window and the length of the first detection window is determined as the length of the second detection window. When the difference is positive, it may indicate that the length of the second detection window is greater than the length of the first detection window, and when the difference is negative, it may indicate that the length of the second detection window is smaller than the length of the first detection window. Alternatively, the network device may also set the first indication information as the ratio or difference of the length of the first detection window relative to the length of the second detection window, and set the second indication information as the length of the second detection window. In this example, The terminal device may determine the size of the length of the first detection window according to the above-mentioned principle, which will not be repeated here.

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

中的一个。需要说明的是，第一检测窗口长度对应的比值，可与第二检测窗口长度对应的比值相同或不相同，本申请对此不做具体限制。For example, the value of the set number of repetitions can be one of {1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048}, and the unit is a valid subframe (ie valid subframe). subframe). The length of the first detection window and the length of the second detection window may both be the set number of repetitions multiplied by a ratio, and the ratio may be

one of the. It should be noted that the ratio corresponding to the length of the first detection window may or may not be the same as the ratio corresponding to the length of the second detection window, which is not specifically limited in this application.

If the network device sets the ratio corresponding to the length of the first detection window to the ratio corresponding to the length of the second detection window to be the same, it means that the network device sets the length of the first detection window and the length of the second detection window to be the same. The ratio corresponding to the length of the first detection window and the ratio corresponding to the second detection window are set to be different, and the terminal device determines the number of repetitions according to the set repetition times and the ratios indicated in the first indication information and the second indication information. The first detection window length and the second detection window length will also be different.

Further, the network device can also set the ratio corresponding to the length of the first detection window to be smaller than the ratio corresponding to the length of the second detection window. In this way, the length of the first detection window configured by the network device will be smaller than the length of the second detection window, which can effectively The resource overhead of sending the sleep signal by the network device is reduced, and the power consumption of the terminal device for detecting the sleep signal is reduced.

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

For example, the network device may set the first indication information as the ratio of the length of the first detection window to the set number of repetitions, and set the second indication information as the ratio or difference of the length of the second detection window relative to the length of the first detection window, After receiving the first indication information and the second indication information, the terminal device can determine the length of the first detection window according to the number of repetitions set, the ratio of the length of the first detection window to the number of repetitions set; and then the length of the first detection window is determined. , the product between the ratio of the length of the second detection window and the length of the first detection window is determined as the length of the second detection window, or the difference between the length of the first detection window, the length of the second detection window and the length of the first detection window can be The sum of the values is determined as the length of the second detection window. When the difference is positive, it may indicate that the length of the second detection window is greater than the length of the first detection window, and when the difference is negative, it may indicate that the length of the second detection window is smaller than the length of the first detection window.

For another example, the network device may also set the first indication information as the ratio or difference of the length of the first detection window relative to the length of the second detection window, and set the second indication information as the difference between the length of the second detection window and the set number of repetitions. ratio, in this example, the terminal device can determine the size of the first detection window length and the second detection window length according to the above-mentioned principle, which will not be repeated here.

In the embodiment of the present application, the network device may also generate the first indication information and the second indication information according to other variant schemes that can be derived or derived based on the above-mentioned various methods, which are not specifically limited in the present application. Based on the foregoing multiple generating manners, the network device may select a manner for generating the first indication information and the second indication information according to the actual situation of the terminal equipment accessing the network equipment. In this way, the network device can effectively improve the flexibility of the network device configuration instruction information and improve the system performance by setting a variety of instruction information generation methods.

In the 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 present application, the network device may send the first indication information and the second indication information in the same broadcast signaling, or may also send the first indication information and the second indication information in different broadcast signaling respectively. Instructions. If the network device sends the first indication information and the second indication information respectively, this embodiment of the present application does not specifically limit the sending order of the two indication information, the first indication information may be sent first, and then the second indication information may be sent, or the reverse Come, send the second indication information first, and then send the first indication information.

Further, in order to facilitate the terminal equipment to detect the paging indication signal, the network equipment can also indicate the time domain position of the paging indication signal in the broadcast signaling (for example, where the wake-up signal or sleep signal is located before the paging opportunity), this The application will not repeat this.

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

In this embodiment of the present application, if the length of the first detection window is not the same as the length of the second detection window, when the terminal device detects the paging indication signal, at the position of the wake-up signal/sleep signal, if the length of the smaller detection window is not If the corresponding paging indication signal is detected, continue to detect the paging indication signal within the larger detection window length. If the corresponding paging indication signal is not detected within the larger detection window length, it is considered that the terminal equipment itself 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 the above steps S301 to S304, the present application also provides a specific embodiment of the message sending method.

In this specific embodiment, the network device may also indicate the coverage range (also referred to as coverage capability or applicable range) of the two types of paging indication signals, the wake-up signal and the sleep signal. The specific embodiment will be described in detail below.

As shown in FIG. 5 , it is a schematic flowchart of a signal sending method provided in this specific embodiment.

Referring to Figure 5, the method further includes:

Step S501: the network device sends first coverage indication information, and/or the network device sends second coverage indication information;

Step S502: The terminal device receives the first coverage indication information sent by the network device, and determines the coverage of the dormant signal according to the first coverage indication information; and/or, the terminal device receives the second coverage indication information sent by the network device, according to the first coverage indication information. The second coverage indication information determines the coverage of the wake-up signal.

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

In the application scenario, in order to meet the detection performance requirements of the paging indication signal by the terminal equipment with poor coverage, the network equipment usually needs to increase the actual signal length of the paging indication signal, and the worse the coverage of the terminal equipment, the network equipment The longer the length of the paging indication signal sent. 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 indication signal required by the terminal equipment with a coverage level of 164dB is significantly larger than that required by the terminal equipment with better coverage. Here, as a way to measure the coverage of the terminal equipment, the coverage level of 144dB/154dB/164dB refers to the attenuation value of the signal received by the terminal equipment from the network equipment. The larger the attenuation value, the worse the coverage of the terminal equipment. That is, in 144dB/154dB/164dB, the coverage situation of the terminal equipment whose coverage level is 164dB is the worst.

However, when the network device sends the paging indication signal, at the position where the wake-up signal/sleep signal appears, regardless of whether the terminal device needs to be paged, the network device needs to send at least one signal, that is, the wake-up signal or the sleep signal. If the signal length of the paging indication signal is increased to meet the detection performance of the terminal equipment with poor coverage, the resource overhead for the network equipment to send the paging indication signal will also increase accordingly. In the foregoing example, considering a terminal device with a coverage level of 164dB, setting the length of the paging indication signal to 70ms is a large network resource overhead. In addition, this part of the increased resource overhead may affect the resource scheduling of other terminal devices, thereby affecting the system performance.

Therefore, the embodiments of the present application can limit the applicability of the wake-up signal and the sleep signal to the terminal equipment with poor coverage by setting the applicable coverage for the two types of paging indication signals of the wake-up signal and the sleep signal, thereby effectively saving The network resources of the system can reduce the negative impact of sending the paging indication signal on the system.

Specifically, the network device may indicate the applicable coverage of the wake-up signal and the sleep signal in various ways. For example, it may only indicate the coverage of the sleep signal, or only the coverage of the wake-up signal, or may indicate both the coverage of the sleep signal. Coverage, also indicates the coverage of the wake-up signal.

In the specific implementation of step 8501, the network device may send first coverage indication information to indicate the coverage of the sleep signal. Wherein, the first coverage indication information may specifically include network parameters for classifying or evaluating the coverage of the terminal equipment, such as signal attenuation value, RSRP value, number of times of repeated NPDCCH reception, and the like. In this way, the network device can send a sleep signal that is only applicable to some terminal devices (that is, the terminal devices located within the coverage of the sleep signal). Accordingly, the terminal device can detect whether it belongs to the coverage of the sleep signal sent by the network device. The sleep signal is used to reduce the resource overhead of sending the sleep signal by the network device, and avoid the negative impact of the excessive resource overhead of sending the sleep signal on the scheduling of the terminal device.

In a possible design, the first coverage indication information may be the 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 whose attenuation value of the signal received from the network device is smaller than the first signal attenuation value to be within the coverage of the dormant signal, and for the terminal device whose attenuation value is greater than or equal to the first signal attenuation value A terminal device with a signal attenuation value considers that its coverage is too poor and is excluded from the coverage of the dormant signal, and cannot use the dormant signal.

It should be noted that, those skilled in the art can specifically set the magnitude of the first signal attenuation value according to the actual requirements for system performance, which is not specifically limited in this application.

For example, the first signal attenuation value may be 164dB. In this way, the terminal devices with coverage levels of 144dB and 154dB are located in the coverage area of the dormant signal and can use the dormant signal, while the terminal device with the coverage level of 164dB is located in the coverage area of the dormant signal. In addition, the sleep signal cannot be used.

By giving the first signal attenuation value in the first coverage information, the dormant signal sent by the network device can only be applied to the terminal device with better coverage, thereby avoiding the detection of the dormant signal by the terminal device with poor coverage. Due to performance requirements, the signal length of the paging indication signal is increased, and the resource overhead for sending the sleep signal by the network device is too large, which is a technical problem that affects the scheduling of other terminal devices.

In a possible design, the first coverage indication information may also be the first power, where the first power is used to evaluate the coverage of the terminal equipment from the dimension of RSRP. The RSRP value of the terminal device represents the reception strength of the signal sent by the network device. The terminal device with a larger RSRP value has a higher signal reception strength and a correspondingly better coverage. Therefore, according to the first power, the network device can set the terminal equipment whose RSRP is greater than the first power to be within the coverage of the dormant signal, while for the terminal equipment whose RSRP is less than or equal to the first power, it is considered that the coverage is too poor , is excluded from the coverage of the sleep signal, and the sleep signal cannot be used.

It should be noted that those skilled in the art can specifically set the magnitude of the first power according to the actual demand for system performance, which is not specifically limited in this application.

By giving the first power in the first coverage information, the dormant signal sent by the network device can also be applied only to the terminal device with better coverage, thereby avoiding the detection performance of the dormant signal by the terminal device with poor coverage. It is a technical problem that the signal length of the paging indication signal is increased, and the resource overhead of sending the sleep signal by the network device is too large, which affects the scheduling of other terminal devices.

In a possible design, the first coverage indication information may also be the first number of repetitions. In practical applications, the network device will repeatedly send the same data to the terminal device, and the terminal device will repeatedly receive it until the The data sent by the network device is successfully detected or correctly decoded. In this example, the terminal device will also record and store its most recent repeated reception times. For a terminal device with poor coverage, the number of repeated receptions is also greater, whereas a terminal device with better coverage has a smaller number of repeated receptions. Therefore, according to the first number of repetitions, the network device can set the terminal equipment that correctly receives the number of repeated receptions of the NPNCCH less than the first number of repetitions to be located within the coverage of the dormant signal, and for the number of repeated receptions greater than or equal to the first number of repetitions The terminal equipment with the number of times is considered that its coverage is too poor and is excluded from the coverage of the dormant signal, and the dormant signal cannot be used.

It should be noted that those skilled in the art can specifically set the size of the first repetition times according to the actual demand for system performance, which is not specifically limited in this application.

By giving the first number of repetitions in the first coverage information, the dormant signal sent by the network device can only be applied to the terminal device with better coverage, thereby avoiding the detection of the dormant signal by the terminal device with poor coverage. Due to performance requirements, the signal length of the paging indication signal is increased, and the resource overhead for sending the sleep signal by the network device is too large, which is a technical problem that affects the scheduling of other terminal devices.

It should be noted that, in the embodiment of the present application, the terminal device can use the sleep signal means that the terminal device can normally detect the sleep signal, and according to the indication of the sleep signal, enter the sleep state during the next paging opportunity, and the terminal device cannot use the sleep signal. 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 instructions of the sleep signal. If a certain terminal device is within the coverage of the sleep signal, it means that it can use the sleep signal, otherwise, it means that the sleep signal cannot be used. Whether the end device can use the wake-up signal is similar.

In the specific implementation of step S501, the network device may also send second coverage indication information to indicate the coverage of the wake-up signal. Wherein, similar to the first coverage indication information, the second coverage indication information may also specifically include network parameters for classifying or evaluating the coverage of the terminal equipment, such as signal attenuation value, RSRP value, number of repeated receptions, etc.; and , in this 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 are not specifically 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. .

In this way, the network device can issue a wake-up signal that is only applicable to some terminal devices (that is, the terminal devices located within the coverage of the wake-up signal). Accordingly, the terminal device can detect the wake-up signal according to whether it belongs to the coverage of the wake-up signal, thereby The resource overhead of sending the wake-up signal by the network device is effectively reduced, and the negative impact of the excessive resource overhead of sending the wake-up signal on the scheduling of the terminal device is avoided.

In a possible design, the second coverage indication information may be a second signal attenuation value, and according to the second signal attenuation value, the network device may assign a terminal receiving a signal from the network device whose attenuation value is smaller than the second signal attenuation value. The device is set to be within the coverage of the wake-up signal, and for the terminal device whose attenuation value is greater than or equal to the second signal attenuation value, the coverage is considered to be too poor and is excluded from the coverage of the wake-up signal, and the wake-up signal cannot be used .

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

Similar to the way of indicating the coverage of the dormant signal, by giving the second signal attenuation value, the wake-up signal sent by the network device can only be used for terminal devices with better coverage, thereby avoiding the need to meet the needs of terminal devices with poor coverage. The requirement for the detection performance of the wake-up signal increases the signal length of the paging indication signal, which results in excessive resource overhead for the network device to send the wake-up signal, which affects the technical problem of scheduling of other terminal devices.

If the network device has indicated the respective applicable coverage areas for both 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 is a signal attenuation value, so the first signal attenuation value and the second signal attenuation value are not equal. Further, the network device may set the first signal attenuation value to be smaller 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 equipment into three categories according to the coverage of the terminal equipment, wherein the first category is the attenuation value less than the first signal attenuation value. Terminal equipment, this type of terminal equipment has the best coverage among the three types of terminal equipment. They are located within the coverage of the sleep signal and the wake-up signal, and can use the sleep signal and the wake-up signal at the same time; the second type is Terminal equipment whose attenuation value is greater than or equal to the first signal attenuation value but less than the second signal attenuation value. Such terminal equipment has the second best or average coverage among the three types of terminal equipment, and is located within the coverage of the wake-up signal, but does not belong to sleep The coverage of the signal, so only the wake-up signal can be used, and the sleep signal cannot be used; the third type is the terminal equipment whose attenuation value is greater than the attenuation value of the second signal. This type of terminal equipment has the worst coverage among the three types of terminal equipment. It does not belong to the coverage of the sleep signal, nor does it belong to the coverage of the wake-up signal, so the sleep signal and wake-up signal cannot be used.

Optionally, the second coverage indication information may also be the second power, and the second power is used to evaluate the coverage of the terminal equipment from the dimension of RSRP. The stronger the signal reception strength is, the better the coverage is. Therefore, according to the second power, the network device can set the terminal equipment whose RSRP is greater than the second power to be within the coverage of the wake-up signal, while for the terminal equipment whose RSRP is less than or equal to the second power, it is considered that its coverage is too poor , is excluded from the coverage of the wake-up signal, and the wake-up signal cannot be used.

It should be noted that those skilled in the art can specifically set the magnitude of the second power according to the actual demand for system performance, which is not specifically limited in this application.

By giving the second power in the second coverage information, the wake-up signal sent by the network device can only be applied to the terminal device with better coverage, thereby avoiding the detection performance of the wake-up signal for the terminal device with poor coverage. It is a technical problem that the signal length of the paging indication signal is increased, and the resource overhead of sending the wake-up signal by the network device is too large, which affects the scheduling of other terminal devices.

If the network device has indicated the respective applicable coverage areas for both 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 Both of the second coverage indication information are power values, so 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. In this way, according to the set first power and second power, the network equipment roughly divides the terminal equipment into three categories according to the coverage of the terminal equipment, wherein the first category is the terminal equipment whose RSRP is greater than the first power. The coverage is the best, they are located within the coverage of the sleep signal and the wake-up signal, and the sleep signal and the wake-up signal can be used at the same time; the second type is the terminal whose RSRP is less than or equal to the first power but greater than the second power Equipment, the coverage of such terminal equipment is the second best or average. They are located in the coverage of the wake-up signal, but they do not belong to the coverage of the sleep signal, so only the wake-up signal can be used, and the sleep signal cannot be used; the third type is that the RSRP is less than the first. Two-power terminal equipment, such terminal equipment has the worst coverage. They neither belong to the coverage of the sleep signal nor the wake-up signal, so 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 is larger than that of the sleep signal, and the wake-up signal can cover a terminal device with a smaller RSRP. There may be some terminal devices with poor coverage that do not belong to the coverage of the sleep signal, and the sleep signal cannot be used. However, because the RSRP of these terminal devices is still greater than the second power and is within the coverage of the wake-up signal, the wake-up signal can be used. .

Optionally, the second coverage indication information may also be the second repetition times, and the second repetition times is used to evaluate the coverage of the terminal equipment according to the dimension of the repeated reception times when the terminal correctly receives the NPDCCH sent by the network device. The smaller the number of repeated receptions, the better the coverage. On the contrary, the larger the number of repeated receptions, the worse the coverage. Therefore, according to the second number of repetitions, the network device can set the terminal device that correctly receives the number of repeated receptions of the NPDCCH sent by the network device is smaller than the number of second repeated receptions to be located within the coverage of the wake-up signal, and for the number of repeated receptions If the terminal equipment with the number of times of repeated reception is greater than or equal to the second, it is considered that its coverage is too poor, and is excluded from the coverage of the wake-up signal, and the wake-up signal cannot be used.

It should be noted that, those skilled in the art can specifically set the size of the second repetition times according to the actual requirements for system performance, which is not specifically limited in this application.

By giving the second number of repetitions in the second coverage information, the wake-up signal sent by the network device can only be applied to the terminal device with better coverage, thereby avoiding the detection of the wake-up signal by the terminal device with poor coverage. Due to performance requirements, the signal length of the paging indication signal is increased, and the resource overhead for sending the wake-up signal by the network device is too large, which affects the technical problem of scheduling of other terminal devices.

In this embodiment of the present application, if the network device indicates the respective applicable coverage areas for 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, then the first repetition The number of times is different from the second repetition. Further, the network device may set the first number of repetitions to be smaller than the second number of repetitions. In this way, according to the set first repetition times and the second repetition times, the network device roughly divides the terminal equipment into three categories according to the coverage of the terminal equipment, wherein the first category is that the repeated reception times of the NPDCCH are less than the first repetition times. Terminal equipment, this type of terminal equipment has the best coverage among the three types of terminal equipment. They are located within the coverage of the sleep signal and the wake-up signal, and can use the sleep signal and the wake-up signal at the same time; the second type is Terminal equipment whose number of repeated receptions of NPDCCH is greater than or equal to the first number of repetitions but less than the second number of repetitions. This type of terminal equipment has the second best or average coverage among the three types of terminal equipment. They are located within the coverage of the wake-up signal, but do not belong to The coverage of the dormant signal, so only the wake-up signal can be used, and the dormant signal cannot be used; the third type is the terminal equipment whose repeated reception times of NPDCCH are greater than the second repetition number, and this type of terminal equipment has the worst coverage among the three types of terminal equipment. , they are neither covered by the sleep signal nor the wake-up signal, so the sleep signal and 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 times is larger than that of the sleep signal, which can cover the terminal equipment with a larger number of repeated NPDCCH receptions. There may be some terminal devices with poor coverage that do not belong to the coverage of the dormant signal and cannot use the dormant signal, but because the number of repeated receptions of the NPDCCH of these terminal devices is still less than the second number of repetitions, and is within the coverage of the wake-up signal, So a wake-up signal can be used.

It should be noted that, in the embodiment of the present application, the terminal device can use the sleep signal means that the terminal device can normally detect the sleep signal, and according to the instruction of the sleep signal, enter the sleep state during the next paging opportunity, and the terminal device cannot use the sleep signal. It means that the terminal device does not detect the sleep signal, or after detecting the sleep signal, does not perform corresponding operations according to the instructions of the sleep signal. If a certain terminal device is within the coverage of the sleep signal, it means that it can use the sleep signal, otherwise, it means that the sleep signal cannot be used. Whether the end device can use the wake-up signal is similar.

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

The second coverage indication information sent by the network device is received, and the coverage range of the wake-up signal is determined according to the second coverage indication information.

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

Optionally, if the first coverage indication information is the first signal attenuation value, then 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 first signal attenuation value, the terminal device can determine that itself If it is outside the coverage of the dormant signal, the dormant signal is ignored, otherwise, the dormant signal is detected based on the length of the first detection window determined in step S304.

Figure 6 is a schematic diagram of a terminal device detecting a signal sent by a network device in this example. As shown in Figure 6, a terminal device with a coverage level of 144dB/154dB is located within the coverage of the dormant signal, and a terminal device with a coverage level of 164dB is located in For example, outside the coverage area of the sleep signal.

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

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

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

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

It should be noted that, in this embodiment of the present application, the terminal device ignoring the sleep signal may be that when the terminal device determines that it is outside the coverage of the sleep signal, the terminal device does not detect the sleep signal, or discards the detected sleep signal , or do 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 the second signal attenuation value, then the terminal detects the signal sent by the network device. 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 The device may determine that it is outside the coverage of the wake-up signal, and ignore the wake-up signal, otherwise, detect the wake-up signal based on the length of the second detection window determined in step S304.

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

Optionally, if the first coverage indication information is the second number of repetitions, the terminal detects the 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 second number of repetitions, the terminal device may determine that it is in the wake-up state. Outside the coverage range of the signal, the wake-up signal is ignored, otherwise, the wake-up signal is detected based on the length of the second detection window determined in step S304.

Based on the above three possible implementation manners, if the terminal device determines that it is within the coverage of the wake-up signal, it detects the wake-up signal. If the terminal device successfully detects the wake-up signal, it confirms that it needs to wake up during the subsequent paging opportunity and monitor the NPDCCH. If the terminal device monitors the NPDCCH during the paging opportunity, it needs to further determine whether the network device has paged itself. If the terminal device confirms that it has been paged, it enters the connected state and prepares to exchange service data with the network device. Otherwise, the continue to be dormant.

It should be noted that, in this embodiment of the present application, the terminal device ignoring the wake-up signal may be that when the terminal device determines that it is 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 the setting operation is not performed according to the indication of the wake-up signal after the wake-up signal is detected, for example, the NPDCCH is not monitored during the subsequent paging opportunity.

In addition, in this embodiment of the present application, the network device may send the above-mentioned first coverage indication information and/or second coverage indication information by sending 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 can use different broadcast signaling to send the first coverage indication information and the second coverage indication information. The first coverage indication information and the second coverage indication information are sent, which is not specifically limited in this application.

This embodiment of the present application also does not impose specific restrictions on the order in which the network device sends the first indication information, the second indication information, and the sending of the first coverage indication information and the second coverage indication information, as long as it is ensured that the terminal device receives the The first indication information, the second indication information, the first coverage indication information, and the second coverage indication information sent by the network device are sufficient.

Further, in this embodiment of the present application, the network device can also activate the limitation of the coverage of the terminal device by the dormant signal by broadcasting or sending dedicated signaling, so that the dormant signal is only applicable to the terminal device within its coverage.

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 whether the terminal device is located in the coverage area of the sleep signal indicated by the first coverage indication information according to the first coverage indication information Inside.

That is to say, the network device can broadcast or send dedicated signaling to trigger whether the terminal device determines whether it is within the coverage of the sleep signal indicated by the first coverage indication information according to the first coverage indication information. thing. Although the network device has set the coverage range for the dormant signal through the first coverage indication information, the network device has not yet enabled the coverage range set for the dormant signal before the network device sends the first activation indication information. At this time, regardless of the coverage of the terminal equipment, all terminal equipments accessing the cell can use the sleep signal sent by the network equipment. Once the network device sends the first activation indication information, it means that the network device has enabled the coverage set for the dormant signal, and the network device limits the applicability of the dormant signal to those located in the A terminal device within the coverage of the dormant signal, correspondingly, the terminal device can detect the dormant signal according to whether it is within the coverage of the dormant signal, thereby reducing the resource overhead of the network device for sending the dormant signal and avoiding the resources for sending the dormant signal. The negative impact of excessive overhead on the system.

Similarly, the network device can 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 a 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 area indicated by the second coverage indication information according to the second coverage indication information within the coverage area of the wake-up signal.

That is to say, the network device can also broadcast or send dedicated signaling to trigger whether the terminal device determines whether it is within the coverage of the wake-up signal indicated by the second coverage indication information according to the second coverage indication information. thing. Similar to the principle that the network device sends the first activation indication information, although the network device has set the coverage for the wake-up signal, the network device has not yet enabled the coverage set for the wake-up signal before the network device sends the second activation indication information. scope. At this time, regardless of the coverage of the terminal equipment, all terminal equipments accessing the cell can use the wake-up signal sent by the network equipment. Once the network device sends the second activation indication information, it means that the network device has enabled the coverage set for the wake-up signal, and the network device limits the applicability of the wake-up signal to those located in the The terminal device within the coverage of the wake-up signal, correspondingly, the terminal device can detect the wake-up signal according to whether it is within the coverage of the wake-up signal, thereby reducing the resource overhead of the network device for sending the wake-up signal and avoiding the resources for sending the wake-up signal The negative impact of excessive overhead on the system.

It should be noted that, in this embodiment of the present application, the network device may send the above-mentioned first activation indication information and/or second activation indication information through a system message. For example, the first activation indication information may be the location set in the system message.

The actual sending length of the paging indication signal will be less than or equal to the configured maximum signal length, but the network device will not indicate the actual sending length of the paging indication signal. Therefore, the terminal device can only know the maximum signal length of the wake-up signal or the sleep signal, but does not know its actual transmission length. For a terminal device that needs to use a wake-up signal or a sleep signal for synchronization, there is a problem of wasting power consumption 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, and use the wake-up signal or sleep signal for synchronization based on this assumption, but the actual transmission length of the wake-up signal or sleep signal may be too short to be used for synchronization.

According to the difference between the information given by the network device in the first duration indication information and the second duration indication information, the terminal device may use various methods to determine the maximum duration and the minimum duration of the wake-up signal. For details, reference may be made to the methods for determining the length of the first detection window and the length of the second detection window described above in this application, which will not be repeated here.

In the specific implementation of step S705, the terminal device may determine whether cell synchronization can be performed through the wake-up signal according to the minimum duration and/or the maximum duration of the wake-up signal.

Specifically, if the terminal device determines that the length of the signal required for cell synchronization is less than the minimum duration, it determines that cell synchronization can be performed through the wake-up signal; or,
