Description

[0001] This application is a divisional application. The original application has the application number 201910755656.7 and the original application date is August 15, 2019. The entire contents of the original application are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of communications, and more specifically to a communication method and related equipment. Background Technology

[0003] During the interaction between network devices and terminal devices, when a network device has downlink data to send to a terminal device, it sends a paging message. The terminal device, in its idle state, needs to listen to the physical downlink control channel (PDCCH) that schedules paging messages.

[0004] To reduce the time terminal devices spend listening to the PDCCH, a discontinuous reception (DRX) mechanism is introduced. Terminal devices only need to listen to the PDCCH during one paging occasion (PO) in each DRX cycle.

[0005] A single terminal device can be assigned a unique Page Entity (PO). However, multiple terminal devices may be listening to the PDCCH on the same PO. In most cases, network devices will not page multiple terminal devices simultaneously on a single PO. For a single terminal device, regardless of whether it has been paged by the network device, it still needs to listen to the PDCCH on the corresponding PO. This can lead to a situation where a large number of terminal devices are listening to the PDCCH without being paged, increasing the power consumption of the unpaged terminal devices. For example, if a PO corresponds to ten terminal devices, and only one of the ten terminal devices is paged, all ten terminal devices will need to listen to the PDCCH. This means the nine unpaged terminal devices will also need to listen to the PDCCH, further increasing their power consumption. Summary of the Invention

[0006] This invention provides a communication method and related equipment for reducing power consumption of terminal devices during interaction with network devices.

[0007] A first aspect of this invention provides a communication method, comprising: a terminal device receiving a first parameter from a first device, the first parameter corresponding to first WUS configuration information in at least one Wake-up Signal (WUS) configuration information, the first WUS configuration information including information on first WUS time-frequency resources; the terminal device determining the first WUS time-frequency resources based on the first parameter; and the terminal device receiving a first WUS from a second device on the first WUS time-frequency resources, the first WUS being used to wake up the terminal device. In this method, the terminal device can determine the first WUS time-frequency resources based on the first parameter received from the first device, and then receive the first WUS from the second device on the first WUS time-frequency resources. The terminal device is only woken up after receiving the first WUS, and then listens to the PDCCH at a first paging time (PO). If the terminal device is not woken up, it does not need to listen to the PDCCH. This reduces the probability of the terminal device listening to the PDCCH but not being paging, thus reducing the power consumption of the terminal device.

[0008] Optionally, in conjunction with the first aspect, in a first possible implementation of the first aspect, the first parameter includes at least one of a first paging probability level, a first paging frequency, and a first paging probability of the terminal device. The first paging frequency can be the frequency at which the terminal device is paged within a preset unit time period, and the first paging probability level and the first paging probability can be determined based on the frequency at which the terminal device is paged within the preset unit time period. The fact that the first parameter includes at least one of the first paging probability level, the first paging frequency, and the first paging probability of the terminal device improves the flexibility of configuring the first parameter.

[0009] Optionally, in conjunction with the first aspect or the first possible implementation of the first aspect, in the second possible implementation of the first aspect, before the terminal device determines the first WUS time-frequency resource based on the first parameter, the method further includes: the terminal device receiving at least one WUS configuration information from the second device; the terminal device determining the first WUS time-frequency resource based on the first parameter includes: the terminal device determining the value range of the first parameter based on the first parameter and at least one pre-set threshold; the terminal device determining the first WUS configuration information from the at least one WUS configuration information based on the value range of the first parameter, wherein there is a pre-set correspondence between the value range of the first parameter and the first WUS configuration information. After determining the first WUS configuration information, the terminal device then determines the first WUS time-frequency resource based on the first WUS configuration information. In the second possible implementation of the first aspect, the first parameter can be a first paging frequency or a first paging probability. The terminal device first determines the value range of the first parameter, then determines the first WUS configuration information, and then determines the first WUS time-frequency resource. In this way, the terminal device can determine the first WUS time-frequency resource corresponding to the first parameter based on the first parameter.

[0010] Optionally, in conjunction with the first aspect or the first possible implementation of the first aspect, in the third possible implementation of the first aspect, before the terminal device determines the first WUS time-frequency resource based on the first parameter, the method further includes: the terminal device receiving at least one WUS configuration information from the second device; the terminal device determining the first WUS time-frequency resource based on the first parameter includes: the terminal device determining the first WUS configuration information from the at least one WUS configuration information based on the first parameter, wherein there is a pre-set correspondence between the first parameter and the first WUS configuration information. After determining the first WUS configuration information, the first WUS time-frequency resource is determined based on the first WUS configuration information. In the third possible implementation of the first aspect, the first parameter can be a first paging probability level, and the terminal device can determine the first WUS configuration information based on the first paging probability level, thereby determining the first WUS time-frequency resource. In this way, the terminal device can determine the first WUS time-frequency resource corresponding to the first paging probability level based on the first paging probability level.

The terminal device is only woken up after receiving the first WUS, and then listens to the PDCCH at the first paging time. If the terminal device is not woken up, it does not need to listen to the PDCCH. This reduces the probability that the terminal device listens to the PDCCH but is not paging, thus reducing the power consumption of the terminal device.

[0012] Optionally, in conjunction with the second aspect, in a first possible implementation of the second aspect, before the second device receives the first paging message from the first device, the method further includes: the second device sending at least one WUS configuration information to the terminal device. The at least one WUS configuration information includes first WUS configuration information.

[0013] Optionally, in conjunction with the second aspect or the first possible implementation of the second aspect, in the second possible implementation of the second aspect, the first parameter includes at least one of a first paging probability level, a first paging frequency, and a first paging probability of the terminal device. The first paging frequency can be the frequency at which the terminal device is paged within a preset unit time period, and the first paging probability level and the first paging probability can be determined based on the frequency at which the terminal device is paged within the preset unit time period. The fact that the first parameter includes at least one of the first paging probability level, the first paging frequency, and the first paging probability of the terminal device improves the flexibility of configuring the first parameter.

[0014] Optionally, in conjunction with the second possible implementation of the second aspect, in the third possible implementation of the second aspect, before the second device sends the first WUS to the terminal device on the first WUS time-frequency resource, the method further includes: the second device determining the value range of the first parameter based on the first parameter and at least one pre-set threshold; the second device determining the first WUS configuration information from at least one WUS configuration information based on the value range of the first parameter, wherein the value range of the first parameter and the first WUS configuration information have a pre-set correspondence. After determining the first WUS configuration information, the second device then determines the first WUS time-frequency resource based on the first WUS configuration information. In the second possible implementation of the second aspect, the first parameter can be a first paging frequency or a first paging probability. The second device first determines the value range of the first parameter, then determines the first WUS configuration information, and then determines the first WUS time-frequency resource. In this way, the second device can determine the first WUS time-frequency resource corresponding to the first parameter based on the first parameter.

[0015] Optionally, in conjunction with the second possible implementation of the second aspect, in the fourth possible implementation of the second aspect, before the second device sends the first WUS to the terminal device on the first WUS time-frequency resource, the method further includes: the second device determining first WUS configuration information from at least one WUS configuration information according to a first parameter, wherein there is a pre-set correspondence between the first parameter and the first WUS configuration information. After determining the first WUS configuration information, the second device then determines the first WUS time-frequency resource based on the first WUS configuration information. In the fourth possible implementation of the second aspect, the first parameter can be a first paging probability level, and the second device can determine the first WUS configuration information based on the first paging probability level, thereby determining the first WUS time-frequency resource. In this way, the second device can determine the first WUS time-frequency resource corresponding to the first paging probability level based on the first paging probability level.

[0016] A third aspect of this invention provides a communication method, comprising: a first device sending a first parameter to a terminal device, the first parameter corresponding to first WUS configuration information in at least one Wake-up Signal (WUS) configuration information, the first WUS configuration information including information on first WUS time-frequency resources; the first device sending a first paging message to a second device, the first paging message including an identifier of the terminal device and the first parameter, the first paging message being used to instruct the second device to paging the terminal device. The first device can send the first parameter to both the terminal device and the second device, enabling both the terminal device and the second device to determine the time-frequency resources of the first WUS based on the first parameter. This ensures that the second device sends the first WUS on the time-frequency resources of the first WUS, and the terminal device receives the first WUS on the time-frequency resources of the first WUS. The terminal device is only woken up after receiving the first WUS, and then listens to the PDCCH at the first paging time. If the terminal device is not woken up, it does not need to listen to the PDCCH. This reduces the probability of the terminal device listening to the PDCCH but not being paging, thus reducing the power consumption of the terminal device.

[0017] Optionally, in conjunction with the third aspect, in a first possible implementation of the third aspect, the first parameter includes at least one of a first paging probability level, a first paging frequency, and a first paging probability of the terminal device. The first paging frequency can be the frequency at which the terminal device is paged within a preset unit time period, and the first paging probability level and the first paging probability can be determined based on the frequency at which the terminal device is paged within the preset unit time period. The fact that the first parameter includes at least one of the first paging probability level, the first paging frequency, and the first paging probability of the terminal device improves the flexibility of configuring the first parameter.

[0018] A fourth aspect of this invention provides a terminal device. The method includes: a receiving unit, configured to receive a first parameter from a first device, the first parameter corresponding to first WUS configuration information in at least one wake-up signal (WUS) configuration information, the first WUS configuration information including information about first WUS time-frequency resources; a processing unit, configured to determine the first WUS time-frequency resources based on the first parameter; and the receiving unit further configured to receive a first WUS from a second device on the first WUS time-frequency resources, the first WUS being used to wake up the terminal device. The terminal device can determine the first WUS time-frequency resources based on the first parameter received from the first device, and then receive the first WUS from the second device on the first WUS time-frequency resources. The terminal device is only woken up after receiving the first WUS, and then listens to the PDCCH at a first paging time (PO). If the terminal device is not woken up, it does not need to listen to the PDCCH. This reduces the probability that the terminal device listens to the PDCCH but is not paging, thus reducing the power consumption of the terminal device.

[0019] Optionally, in conjunction with the fourth aspect, in a first possible implementation of the fourth aspect, the terminal device includes: a receiving unit, further configured to receive at least one WUS configuration information from a second device; a processing unit, further configured to determine the value range of the first parameter based on a first parameter and at least one preset threshold; and a processing unit, further configured to determine first WUS configuration information from the at least one WUS configuration information based on the value range of the first parameter, wherein the value range of the first parameter corresponds to a preset relationship between the first WUS configuration information and the first WUS configuration information.

The second device sends the first WUS to the terminal device on the first WUS time-frequency resources, the first WUS being used to wake up the terminal device. The terminal device is only woken up after receiving the first WUS, and then listens to the PDCCH at the first paging time. If the terminal device is not woken up, it does not need to listen to the PDCCH. This reduces the probability of the terminal device listening to the PDCCH but not being paging, thus reducing the power consumption of the terminal device.

The first device can transmit the first parameter to both the terminal device and the second device, enabling both the terminal device and the second device to determine the time-frequency resources of the first WUS based on the first parameter. This ensures that the second device transmits the first WUS on the time-frequency resources of the first WUS, and the terminal device receives the first WUS on the time-frequency resources of the first WUS. The terminal device is only woken up after receiving the first WUS, and then listens to the PDCCH at the first paging time. If the terminal device is not woken up, it does not need to listen to the PDCCH. This reduces the probability of the terminal device listening to the PDCCH but not being paging, thus reducing the power consumption of the terminal device.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] The term "and / or" appearing in this application can describe the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "or" relationship.

[0040] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or modules is not necessarily limited to those steps or modules explicitly listed, but may include other steps or modules not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0041] During the interaction between network devices and terminal devices, when a network device needs to send downlink data to a terminal device, it sends a paging message to the terminal device. The terminal device listens to the PDCCH for its corresponding PO in each DRX cycle.

[0042] The terminal device can determine the paging frame (PF) based on the DRX period and the terminal device's unique identifier, and then determine the paging subframe, which is the PO. The system frame number (SFN) of the PF is calculated using the following formula:

[0043] SFN mod T = (T div N) * (UE_ID mod N). Where T is the period of DRX, N = min(T, nB), nB = 4T, 2T, T, T / 2, T / 4, T / 8... (the value of nB is notified to the UE by the network device through system messages), UE_ID = International Mobile Subscriber Identification (IMSI) mod 1024.

[0044] A system frame consists of ten paging subframes. The paging subframe number corresponding to PO can be obtained from i_s, which can be calculated using the following formula:

[0045] i_s=floor(UE_ID / N) mod Ns, where UE_ID=IMSI mod 1024, N=min(T, nB), nB=4T, 2T, T, T / 2, T / 4, T / 8..., Ns=max(1, nB / T).

[0046] Based on the calculated value of i_s, determine the paging subframe number that needs to be monitored from Table 1:

[0047] Table 1

[0048]

[0049] Through the above process, a unique Point of Purchase (PO) can be identified for each terminal device, and that terminal device listens to the PDCCH on that PO. However, a PO may correspond to multiple terminal devices, meaning multiple terminal devices may listen to the PDCCH on the same PO. In most cases, network devices will not page multiple terminal devices simultaneously on one PO. However, for a single terminal device, regardless of whether it has been paged by the network device, it needs to listen to the PDCCH on every PO. This can lead to a large number of terminal devices corresponding to the same PO listening to the PDCCH without being paged, increasing the power consumption of the unpaged terminal devices. For example, if a PO corresponds to ten terminal devices, and only one of the ten terminal devices is paged, all ten terminal devices need to listen to the PDCCH. This means the nine unpaged terminal devices also need to listen to the PDCCH, increasing their power consumption.

[0050] Therefore, Embodiment 1 of the present invention provides a communication method, such as... Figure 1 As shown, the method may include:

[0051] 101. The first device sends the first parameter to the terminal device.

[0052] The first device sends a first parameter to the terminal device. This first parameter can be a first paging frequency and / or a first paging probability for the terminal device. The first paging frequency is the number of times the terminal device is paged per unit time, which can be a pre-set time period, without specific limitation. For example, the first parameter could be 20 times / hour, meaning the terminal device is paged 20 times in one hour. The first paging probability can be the probability that the terminal device is paged in a corresponding PO. For example, the first paging probability could be 20%, meaning the probability that the terminal device is paged in the PO corresponding to the terminal device is 20%. This first paging probability can be determined by the first device based on the probability that all terminal devices corresponding to a PO are paged within a unit time. For example, if there are ten terminal devices corresponding to one PO, and the terminal device that is paged the most times within a unit of time is paged 100 times, while the terminal device that is paged the least times is paged 20 times, then the first device can determine that the first paging probability of the terminal device that is paged the most times is 100%, and the first paging probability of the terminal device that is paged the least times is 20%. This example is only for explaining this application and should not be construed as limiting it. The first parameter is used to instruct the terminal device to determine the first WUS configuration information in at least one wake-up signal (WUS) configuration information.

[0053] The first device can be a core network device, such as a mobility management entity (MME) or an access and mobility management function (AMF), but is not limited to these. The terminal device can be user equipment (UE), an Internet of Things (IoT) device, etc., but is not limited to these. Furthermore, the paging of the terminal device is regular, with a fixed frequency within a pre-defined time period. For example, if the terminal device is paged 20 times between 9:00 and 10:00 on January 1, 2010, then the terminal device will also be paged 20 times between 10:00 and 11:00 on January 1, 2010. This example is only for explaining this application and should not be construed as limiting it.

[0054] It is understandable that the first device can send the first parameter to the terminal device via other devices, including the second device. In other words, step 101 could involve the first device sending the first parameter to the second device, and the second device then sending the first parameter to the terminal device; there are no restrictions on this.

[0055] It should be noted that before sending the first parameter to the terminal device, the first device needs to obtain the first parameter first. The first device can count the number of times the terminal device is paged within a preset unit of time and record this number as the value of the first parameter. For example, if the preset unit of time is one hour, and the first device is paged 20 times within one hour, the first device can count the value of the first parameter as 20. This example is only for explaining this application and should not be construed as limiting it.

[0056] For example, the first device may send an attach accept message or a tracking area update accept message to the terminal device, the attach accept message or tracking area update accept message carrying the first parameter.

[0057] 102. The first device sends a first paging message to the second device.

[0058] The first device sends a first paging message to the second device. The first paging message includes the identifier of the terminal device and the first parameter. The first paging message is used to instruct the second device to page the terminal device. The identifier of the terminal device is used by the second device to identify the terminal device. The first parameter can be the first paging frequency of the terminal device. The first parameter is used to instruct the second device to determine the first WUS configuration information in at least one WUS configuration information.

[0059] The second device can be an access network device, such as an evolved Node B (E-UTRAN node B, eNB), a 5G base station (gNB), or an evolution universal mobiletelecommunications system terrestrial radio access network (E-UTRAN).

[0060] 103. The second device sends at least one WUS configuration message to the terminal device.

[0061] The second device sends at least one WUS configuration information to the terminal device, the at least one WUS configuration information containing at least one first WUS configuration information corresponding to the terminal device. The first WUS configuration information contains first WUS time-frequency resources.

[0062] The at least one WUS configuration information corresponds to the first parameter. Specifically, the at least one WUS configuration information may correspond to the value range of the first parameter. For example, the at least one WUS configuration information may contain K WUS configuration information. Any one of the K WUS configuration information can be denoted as WUS. j Configuration information, where K is a positive integer and j is a positive integer less than or equal to K. Each WUS configuration information has a corresponding index. The corresponding WUS configuration information can be determined based on the index of any given WUS configuration information. One or more paging frequency thresholds can be preset. Based on these thresholds, at least two value ranges can be determined, each of which corresponds to an index of a WUS configuration information. This index can be explicit or implicit. In the explicit method, a value range of V corresponds to a specific index value, and a specific index value corresponds to a WUS configuration information, as shown in Table 2. In the implicit method, the index of a WUS configuration information does not have a specific value and can be represented in other implicit ways. For example, K WUS configuration information are represented in list form, without a column for the index of the WUS configuration information. The first row of the list implicitly indicates that the index of the first WUS configuration information is 1... The Kth row of the list implicitly indicates that the index of the Kth WUS configuration information is K. The list implicitly corresponds to index values ​​from 1 to K for each WUS configuration file, from the first to the Kth. The value of this first parameter can be denoted as V. When the value of V is determined, the range of values ​​corresponding to that value can be determined, thereby determining the index of the WUS configuration file corresponding to that range. Then, the corresponding WUS configuration file is determined based on its index. The correspondence between the range of V values, the index of the WUS configuration file, and the WUS configuration files is shown in Table 2 below.

[0063] Table 2

[0064] The range of values ​​for V Index of WUS configuration information WUS Configuration Information <![CDATA[V≤T1]]> <![CDATA[Index of WUS1 configuration information]]> <![CDATA[WUS1 configuration information]]> <![CDATA[T1<V≤T2]]> <![CDATA[Index of WUS2 configuration information]]> <![CDATA[WUS2 configuration information]]> …… …… …… <![CDATA[T M-1 <V≤T M ]]> <![CDATA[WUS K-1 Index of configuration information <![CDATA[WUS K-1 Configuration Information <![CDATA[T M <In]]> <![CDATA[WUS K Index of configuration information <![CDATA[WUS K Configuration Information

[0065] Among them, T1, T2, ..., T M-1 T M For a pre-set threshold, the relationship between them can be T1≤T2≤……≤T M-1 ≤T M In practical implementation, multiple V value ranges can correspond to an index of WUS configuration information and a WUS configuration information. For example, in Table 2, multiple rows in the first column correspond to one row in the second column and one row in the third column. The second device can send a system message to the terminal device. This system message can contain M pre-set thresholds, such as: T1, T2, ..., T M-1 TM .

[0066] In actual implementation, the index of this WUS configuration information can be a multi-level index. For example, the first-level index can include at least one second-level index. A first-level index can be determined based on the value range of the first parameter, and then the specific second-level indexes within that first-level index are determined according to a preset method. Each second-level index corresponds to a specific piece of WUS configuration information. Specifically, determining the second-level indexes within the first-level index according to the preset method can involve determining the second-level indexes within the first-level index based on the identifier of the terminal device.

[0067] For example, the preset method can be as follows: First, number the secondary indices in order from 1 to W, where B is the number of the secondary index corresponding to the terminal device. W is the number of secondary indices contained in the primary index, W is a positive integer, and M is the unique identifier of the terminal device, such as the serving-temporary mobile subscriber identity (S-TMSI) or IMSI. Then, the formula for calculating B can be: B = M mod W + Q, where Q is a positive integer greater than or equal to zero and less than W, and mod is the modulo operation. This example is only used to explain this application and should not be construed as limiting it.

[0068] After determining the primary and secondary indexes using the method described above, a specific WUS configuration can be determined based on these primary and secondary indexes. For example, this WUS... K The index can be a first-level index, which can include WUS K1 WUS K1 WUS K3 ...at least one secondary index, each secondary index corresponding to a WUS configuration information. After determining the primary index based on the value range of the first parameter, the specific corresponding secondary index is determined based on the identifier of the terminal device. Then, the WUS configuration information is determined according to Table 3. Table 3 shows the correspondence between the primary index, secondary index, and WUS configuration information. Table 3 is only an example and does not constitute a limitation.

[0069] Table 3

[0070]

[0071] The second device can send the correspondence between the aforementioned value range and the index of the WUS configuration information to the terminal device. After receiving the correspondence, the terminal device can determine the value range of V based on the value of the first parameter (V), thereby determining the index of the WUS configuration information corresponding to the value range and the corresponding WUS configuration information.

[0072] In another implementation, the configuration information may include two parts: the correspondence between the first parameter and the WUS index shown in Table 4, and the correspondence between the index of the WUS configuration information and the WUS configuration information shown in Table 5.

[0073] Table 4

[0074]

[0075]

[0076] The relationship between the index of the WUS configuration information and the WUS configuration information can be shown in Table 5 below. The index of the WUS configuration information can be implicit. For example, the WUS configuration information is given in the form of a list, and the order of the WUS configuration information in the list implicitly indicates the index of the WUS configuration information.

[0077] Table 5

[0078] WUS Configuration Number Index of WUS configuration information WUS Configuration Information 1 <![CDATA[Index of WUS1 configuration information]]> <![CDATA[WUS1 configuration information]]> 2 <![CDATA[Index of WUS2 configuration information]]> <![CDATA[WUS2 configuration information]]> …… …… …… K-1 <![CDATA[WUS K-1 Index of configuration information <![CDATA[WUS K-1 Configuration Information K <![CDATA[WUS K Index of configuration information <![CDATA[WUS K Configuration Information

[0079] The second device can send the correspondence between the value range of V described in Table 4 and the index of WUS configuration information, as well as the relationship between the index of WUS configuration information and WUS configuration information described in Table 5, to the terminal device. After receiving the first parameter, the terminal device can determine the index of WUS configuration information according to Table 4, and then determine the corresponding WUS configuration information according to Table 5.

[0080] The above is only one implementation method. In actual implementation, the WUS configuration information can also be determined directly based on the value range of the first parameter, without needing to determine the index of the WUS configuration information. This is not limited here.

[0081] It should be noted that there is no temporal order between steps 102 and 103. The first device can send the first paging message to the second device after the second device sends at least one WUS configuration information to the terminal device.

[0082] 104. The terminal device determines the value range of the first parameter and determines the first WUS configuration information from the at least one WUS configuration information.

[0083] As described in step 103 above, the terminal device can determine the value range of the first parameter based on the first parameter and at least one preset threshold, and then determine the first WUS configuration information from the at least one WUS configuration information based on the value range of the first parameter and the preset correspondence between the value range of the first parameter and the first WUS configuration information.

[0084] Optionally, in one possible implementation, the terminal device can determine the value range of the first parameter based on the first parameter and at least one pre-set threshold, thereby determining the index of the WUS configuration information corresponding to the value range. This index of the WUS configuration information corresponding to the value range is the index of the first WUS configuration information. Then, the first WUS configuration information is determined based on the index of the WUS configuration information corresponding to the value range. This can be understood with reference to step 103.

[0085] Optionally, in one possible implementation, the terminal device can determine the value range of the first parameter based on the first parameter and at least one pre-set threshold, and then directly determine the first WUS configuration information corresponding to the value range based on the value range of the first parameter. This can be understood with reference to step 103.

[0086] Optionally, in one possible implementation, the terminal device can determine the value range of the first parameter based on the first parameter and at least one pre-set threshold, thereby determining the primary index corresponding to the value range. The primary index may include at least one secondary index, which the terminal device can determine using a preset method. Specifically, it can determine the secondary index within the primary index based on the terminal device's identifier. This determination step can be understood with reference to step 103, and will not be elaborated here. After determining the secondary index, the first WUS configuration information can be determined based on the secondary index.

[0087] 105. The terminal device determines the first WUS time-frequency resources based on the first WUS configuration information.

[0088] The first WUS configuration information contains information about the first WUS time-frequency resources, and the terminal device can determine the first WUS time-frequency resources based on the first WUS configuration information.

[0089] The first WUS time-frequency resource may include at least one of the following:

[0090] (1) Maximum duration information of WUS, which is used to indicate the maximum duration of the wake-up signal WUS;

[0091] (2) PO number, which indicates the number of POs associated with a WUS;

[0092] (3) Number of UE groups, which indicates the number of UE groups associated with a WUS or the number of UE groups associated with a PO;

[0093] (4) Frequency location information, used to indicate the frequency location of the transmitted WUS; in one possible implementation, the frequency location information can be used to indicate the frequency location of the transmitted WUS in the paging narrowband.

[0094] (5) Time location information, used to indicate the time location of sending WUS; in one possible implementation, the time location information can be used to indicate the time location of sending WUS relative to PO, such as the end time of sending WUS and the time of the first associated PO.

[0095] 106. The second device determines the first WUS configuration information from the at least one WUS configuration information based on the first parameter.

[0096] The second device can determine the value range of the first parameter based on the first parameter and at least one preset threshold, and then determine the first WUS configuration information from the at least one WUS configuration information according to the preset correspondence between the value range of the first parameter and the first WUS configuration information. This determination process can be understood with reference to step 104, and will not be repeated here.

[0097] It should be noted that steps 106 and 104 are not sequential in time. Either the terminal device can determine the first WUS configuration information first, or the second device can determine the first WUS configuration information first.

[0098] 107. The second device determines the first WUS time and frequency resources based on the first WUS configuration information.

[0099] The first WUS configuration information includes information about the first WUS time-frequency resources. The second device can determine the first WUS time-frequency resources based on the first WUS configuration information. The first WUS time-frequency resources are as described in step 105, and will not be repeated here.

[0100] 108. The second device sends the first WUS to the terminal device on the first WUS time-frequency resource.

[0101] After determining the first WUS time-frequency resource in step 107, the second device sends the first WUS to the terminal device on the first WUS time-frequency resource.

[0102] 109. The terminal device receives the first WUS from the second device on the first time-frequency resource.

[0103] After determining the first WUS time-frequency resource in step 105, the terminal device receives the first WUS on the first WUS time-frequency resource. The first WUS is used to wake up the terminal device. After being woken up, the terminal device listens to the PDCCH at the first PO, which is the PO corresponding to the terminal device.

[0104] This application provides a communication method in embodiment one, comprising: a terminal device receiving a first parameter from a first device, the first parameter being a first paging frequency of the terminal device. The first parameter corresponds to first WUS configuration information in at least one Wake-up Signal (WUS) configuration information, the first WUS configuration information including information on first WUS time-frequency resources; the terminal device determining the first WUS time-frequency resources according to the first parameter; and the terminal device receiving a first WUS from a second device on the first WUS time-frequency resources, the first WUS being used to wake up the terminal device and cause the terminal device to listen to the Physical Downlink Control Channel (PDCCH) at the first paging time. In this method, the terminal device can determine the first WUS time-frequency resources according to the first parameter received from the first device, and then receive the first WUS from the second device on the first WUS time-frequency resources. After receiving the first WUS, the terminal device listens to the PDCCH at the first paging time, which can reduce the probability that the terminal device listens to the PDCCH but is not paging, thereby reducing the power consumption of the terminal device.

[0105] In Embodiment 1 of this application, the frequency of paging of a terminal device within a unit time period can be determined based on the frequency of paging of the terminal device within a unit time period and one or more pre-set thresholds. This value range corresponds to a specific WUS. Multiple terminal devices corresponding to the same PO may have different paging frequencies within a unit time period, thus multiple terminals corresponding to one PO may correspond to different WUS.

[0106] Therefore, the scheme provided in Embodiment 1 of this application is equivalent to grouping multiple terminals corresponding to a PO based on different WUS. Among all terminal devices corresponding to a PO, only the terminal device that receives the corresponding WUS listens to the PDCCH, instead of all terminal devices in the PO listening to the PDCCH, which can reduce the power consumption of terminal devices that are not paged. Before implementing this scheme, the first device needs to determine whether the second device and the terminal devices support the mechanism of grouping terminal devices based on WUS. For example, the second device can send a first indication message to the first device, and the first device determines that the second device supports WUS-based grouping of terminal devices based on the first indication message; the terminal device can send a second indication message to the first device, and the first device determines that the terminal device supports WUS-based grouping of terminal devices based on the second indication message. For example, the terminal device can carry the second indication message through an attach request message or a tracking area update request.

[0107] In Embodiment 1, the first parameter is the first paging frequency or the first paging probability of the terminal device. The first paging frequency can be the number of times the terminal device is paged per unit time, and the first paging probability can be the probability that the terminal device is paged in the corresponding PO. Both the first paging frequency and the first paging probability can be represented numerically, and the value range can be determined based on the numerical value. In another embodiment, the first parameter can also be the first paging probability level of the terminal device. The first paging probability level can represent the probability level of the terminal device being paged per unit time, and the first paging probability level is determined by the first device based on the number of times the terminal device is paged per unit time. Embodiment 2 provides a communication method, referring to... Figure 2 The method may include:

[0108] 201. The first device sends the first parameter to the terminal device.

[0109] The first device sends a first parameter to the terminal device. This first parameter can be a first paging probability level, which is the paging probability level of the terminal device within a unit of time. This first paging probability level is determined by the first device based on the number of times the terminal device is paged within that unit of time. The unit of time can be a pre-set time period, and its specific location is not limited. For example, the first parameter can indicate whether the first paging probability level is low or high. For instance, if the first device counts that the terminal device is paged less than or equal to 20 times in one hour, then the paging probability level of the terminal device is determined to be low; if the first device counts that the terminal device is paged more than 20 times in one hour, then the paging probability level of the terminal device is determined to be high. The first parameter can also be other probability levels, such as level 1, level 2, etc. This example is only for explaining this application and should not be construed as limiting it.

[0110] The first device can be a core network device, such as an MME and an AMF, but is not limited to these. The terminal device can be a UE, an IoT device, etc., but is not limited to these. The paging of the terminal device is regular. The frequency of paging within a pre-set time period is fixed. Therefore, the probability level of being paging within a pre-set time period is fixed.

[0111] It is understandable that the first device can send the first parameter to the terminal device via other devices, including the second device. In other words, step 201 could involve the first device sending the first parameter to the second device, which would then send the first parameter to the terminal device; this is not restricted.

[0112] 202. The first device sends a first paging message to the second device.

[0113] A first device sends a first paging message to a second device. This first paging message includes the identifier of the terminal device and the first parameter. The first paging message instructs the second device to page the terminal device, and the identifier of the terminal device is used by the second device to identify the terminal device. The first parameter can be the first paging probability level of the terminal device, and this first parameter instructs the second device to determine first WUS configuration information from at least one WUS configuration information. The second device can be an access network device, such as an eNB, gNBE-UTRAN, etc.

[0114] 203. The second device sends at least one WUS configuration message to the terminal device.

[0115] The second device sends at least one WUS configuration information to the terminal device, the at least one WUS configuration information containing at least one first WUS configuration information corresponding to the terminal device. The first WUS configuration information contains first WUS time-frequency resources.

[0116] The at least one WUS configuration information corresponds to a paging probability level. For example, when the paging probability level is low or high, the correspondence between the at least one WUS configuration information and the paging probability level can be shown in Table 6 below:

[0117] Table 6

[0118] Paging probability level WUS Configuration Information Low <![CDATA[WUS1 configuration information]]> high <![CDATA[WUS2 configuration information]]>

[0119] In actual implementation, multiple paging probability levels can be associated with one WUS configuration information. For example, when the paging probability levels include five levels: high, second-high, medium, second-low, and low, the correspondence between the paging probability levels and the WUS configuration information can be shown in Table 7 below:

[0120] Table 7

[0121] Paging probability level WUS Configuration Information Low or second lowest <![CDATA[WUS1 configuration information]]> middle <![CDATA[WUS2 configuration information]]> Second highest <![CDATA[WUS3 configuration information]]> high <![CDATA[WUS4 configuration information]]>

[0122] The second device can send the correspondence between the above WUS configuration information and the paging probability level to the terminal device. After receiving the correspondence, the terminal device can determine the corresponding WUS configuration information based on the terminal device's first paging probability level.

[0123] The correspondence between at least one WUS configuration information and paging probability level described above is merely an exemplary implementation and does not constitute a limitation on this application. In actual implementation, it is possible to set N paging probability levels, where N is a positive integer. It is possible to set one or more paging probability levels corresponding to one WUS configuration information; this is not limited here.

[0124] 204. The terminal device determines the first WUS configuration information from the at least one WUS configuration information based on the first parameter.

[0125] The terminal device determines the first WUS configuration information from the at least one WUS configuration information based on the first parameter and the pre-set correspondence between the first parameter and the first WUS configuration information. For example, referring to step 203, if the first parameter is "low", then the first WUS configuration information is determined to be WUS1 configuration information based on the correspondence between the at least one WUS configuration information and the paging probability level.

[0126] 205. The terminal device determines the first WUS time-frequency resources based on the first WUS configuration information.

[0127] Referring to step 105 in Example 1, it will not be repeated here.

[0128] 206. The second device determines the first WUS configuration information from the at least one WUS configuration information based on the first parameter and the pre-set correspondence between the first parameter and the first WUS configuration information.

[0129] The second device determines the first WUS configuration information from the at least one WUS configuration information based on the first parameter and the pre-set correspondence between the first parameter and the first WUS configuration information. The determination process can be understood with reference to step 204, and will not be repeated here.

[0130] It should be noted that steps 206 and 204 are not sequential in time. Either the terminal device determines the first WUS configuration information first, or the second device determines the first WUS configuration information first.

[0131] 207. The second device determines the first WUS time and frequency resources based on the first WUS configuration information.

[0132] Refer to step 107 in Example 1 for further understanding; it will not be repeated here.

[0133] 208. The second device sends the first WUS to the terminal device on the first WUS time-frequency resource.

[0134] After determining the first WUS time-frequency resource in step 207, the second device sends the first WUS to the terminal device on the first WUS time-frequency resource.

[0135] 209. The terminal device receives the first WUS from the second device on the first time-frequency resource.

[0136] After determining the first WUS time-frequency resource in step 205, the terminal device receives the first WUS on the first WUS time-frequency resource. The first WUS is used to wake up the terminal device and enable the terminal device to listen to the PDCCH at the first PO, where the first PO is the PO corresponding to the terminal device.

[0137] Embodiment 2 of this application provides a communication method, which includes: a terminal device receiving a first parameter from a first device, the first parameter being a first paging probability level of the terminal device. The first parameter corresponds to first WUS configuration information in at least one Wake-up Signal (WUS) configuration information, the first WUS configuration information including information on first WUS time-frequency resources; the terminal device determining the first WUS time-frequency resources according to the first parameter; the terminal device receiving a first WUS from a second device on the first WUS time-frequency resources, the first WUS being used to wake up the terminal device and cause the terminal device to listen to the Physical Downlink Control Channel (PDCCH) at the first paging time. In this method, the terminal device can determine the first WUS time-frequency resources according to the first parameter received from the first device, and then receive the first WUS from the second device on the first WUS time-frequency resources. After receiving the first WUS, the terminal device listens to the PDCCH at the first paging time, which can reduce the probability that the terminal device listens to the PDCCH but is not paging, thus reducing the power consumption of the terminal device.
