Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular, to a method and apparatus for configuring DCP resources of a PDCCH. Background Art

[0002] In related technologies, a communication system mainly saves power through a Discontinuous Reception (DRX) function. A network device configures a DRX active period for a terminal device based on a certain algorithm. The terminal device performs data transceiver processing during the configured DRX active period. During other silent periods, the terminal device does not listen to a Physical Downlink Control Channel (PDCCH) channel, thereby achieving the purpose of power saving.

[0003] Since the DRX active period has a fixed length and is periodically woken up, it is not conducive to relatively more flexible power saving based on service changes. In some cases, the actual service of the terminal device may not need to be woken up periodically in the next DRX active period. Therefore, how to achieve synchronization and coordination between the network device and the terminal device and improve the flexibility of power saving has become one of the important research directions.

[0034] In the embodiments of the present invention, the term "and / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0035] In the embodiments of the present disclosure, the term "a plurality of" means two or more, and other quantifiers are similar thereto.

[0036] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

[0037] Figure 1 The flowchart of a method for configuring DCP resources of a PDCCH provided by an embodiment of the present disclosure is as Figure 1 shown, and the method includes the following steps:

[0038] S101, determine the basic PS-RNTI within the DRX cycle, the basic PS-RNTI transmission timing of the basic PS-RNTI, and the basic wake-up indication bit corresponding to the target format of the DCI.

[0039] RNTI is a Radio Network Temporary Identifier, which is used to distinguish / identify terminal devices connected in a cell, a specific radio channel, a group of terminal devices in a paging situation, a group of terminal devices for which power control is issued by a 4G network device, and system information sent by the network device for all terminal devices. The Power Saving Radio Network Temporary Identity (PS-RNTI) is an RNTI used for power saving, and the PS-RNTI can be an identifier.

[0040] In the embodiments of the present disclosure, the target format of the Downlink Control Information (DCI) is DCI2-6, and DCI2-6 can be used to notify power-saving information outside the DRX active time of one or more terminal devices. In the embodiments of the present disclosure, the basic wake-up indication bit corresponding to the target format of the DCI is the basic DCI2-6Position.

[0041] In order to achieve the synchronization and coordination between the network device and the terminal device, when the terminal device performs PDCCH power-saving adaptation, it is necessary to maintain and allocate the DCP resources in the energy-saving indication function process.

[0042] In some implementations, the basic PS-RNTI within the DRX cycle, the basic PS-RNTI transmission timing of the basic PS-RNTI, and the basic DCI2-6 Position are configured in combination with the protocol specifications and the actual needs of the terminal device.

[0043] S102, based on the basic PS-RNTI, the basic PS-RNTI transmission timing, and the basic wake-up indication bit, obtain the configuration information of the DCP resources, and the configuration information is used to instruct the terminal device to save power.

[0044] In some implementations, obtain the hierarchical relationship among the DRX cycle, the base PS-RNTI, the base PS-RNTI transmission timing, and the base DCI2-6 Position, and determine the transmission cycle corresponding to DCI2-6, that is, the configuration information in the DCI2-6 transmission cycle, in combination with the protocol specification, the Operation Administration and Maintenance (OAM) configuration, and the hierarchical relationship.

[0045] Optionally, the DCP resource is a DCI resource scrambled with the PS-RNTI.

[0046] Optionally, the configuration information of the DCP resource includes the target DCI2-6 Position, the target PS-RNTI, and the target power saving offset PS-offset. Among them, the target DCI2-6 Position is determined from the base DCI2-6 Position, and the target PS-RNTI is determined from the base PS-RNTI.

[0047] In the embodiments of the present disclosure, first determine the base PS-RNTI within the DRX cycle, the base PS-RNTI transmission timing of the base PS-RNTI, and the base DCI2-6 Position, and then obtain the configuration information of the DCP resource based on the base PS-RNTI, the base PS-RNTI transmission timing, and the base DCI2-6 Position. The configuration information is used to instruct the terminal device to save power. The present disclosure can support relatively more flexible power saving based on service changes, provide a reference for realizing the synchronization and coordination of network devices and terminal devices, configure the DCP resources in the power saving indication function process, and improve the flexibility of power saving.

[0048] Figure 2 The following is a flowchart of a method for configuring the DCP resource of a PDCCH provided by the embodiments of the present disclosure. As Figure 2 shown, based on the above embodiments, the method includes the following steps:

[0049] S201, determine the hierarchical relationship of various resources within the DRX cycle.

[0050] In the embodiments of the present disclosure, for any DRX cycle, there are K base PS-RNTI transmission timings within the DRX cycle, there are C base PS-RNTIs within any base PS-RNTI transmission timing, and there are L base DCI2-6 Positions for any base PS-RNTI. Among them, K, C, and L are integers greater than 1. Optionally, in the embodiments of the present disclosure, L can take the maximum value of the DCI2-6 length in the Rel-16 protocol, that is, 140.

[0051] S202. Based on the hierarchical relationship, determine the hierarchy to which the base PS-RNTI belongs, the hierarchy to which the transmission occasion of the base PS-RNTI belongs, and the hierarchy to which the base wake-up indication bit belongs.

[0052] Figure 3 The figure is a schematic diagram of a hierarchical relationship provided by an embodiment of the present disclosure. As Figure 3 shown, in the embodiment of the present disclosure, according to the hierarchical relationship of various resources within the DRX cycle, the DRX cycle can be divided into four hierarchies, namely the cycle duration type layer (Tdrx Type layer) of the DRX cycle, the send occasion layer (Send Occassion layer), the PS-RNTI layer (PS-RNTI layer), and the DCI2-6 Position layer (DCI2-6 Position layer); mapped to the embodiment of the present disclosure, the DRX cycle is the upper level of the transmission occasion of the base PS-RNTI, the transmission occasion of the base PS-RNTI within each DRX cycle is the upper level of the base PS-RNTI, and the base DCI2-6 Position is the lower level of the base PS-RNTI.

[0053] S203. Dynamically generate the configuration information of the DCP resources based on the hierarchy to which the base PS-RNTI belongs, the hierarchy to which the transmission occasion of the base PS-RNTI belongs, and the hierarchy to which the base wake-up indication bit belongs.

[0054] For the introduction of step S203, reference can be made to the relevant introduction in the above embodiment, which will not be elaborated here.

[0055] The present disclosure can support relatively more flexible power saving based on service changes, provide a reference for achieving synchronous coordination between network devices and terminal devices, configure the DCP resources in the energy saving indication function process, and improve the flexibility of power saving.

[0056] Figure 4 The figure is a flowchart of a method for configuring DCP resources of a PDCCH provided by an embodiment of the present disclosure. As Figure 4 shown, on the basis of the above embodiment, the method includes the following steps:

[0057] S401. Obtain the candidate PS-RNTI and the candidate PS-RNTI transmission occasion configured for the DRX cycle.

[0058] In some implementations, the required number of basic PS-RNTIs within a DRX cycle is obtained according to the number of DRX terminal devices and the target format length of the DCI configured for the DRX cycle, that is, the DCI2-6 length. Optionally, the number of DRX-configured users configured by OAM and the number of Pdcch DRX energy-saving adaptive terminal devices can be obtained respectively, and the smaller value of the two is used as the value of the number of DRX terminal devices. The required number of basic PS-RNTIs within any DRX cycle can be obtained using the following formula:

[0059] PS-rntiNumOfEachTdrx = NUM DRXUE / SizeDci2-6

[0060] where PS-rntiNumOfEachTdrx is the required number of basic PS-RNTIs within any DRX cycle, NUM DRXUE is the number of DRX terminal devices, and SizeDci2-6 is the DCI2-6 length configured for the DRX cycle.

[0061] Based on the required number of basic PS-RNTIs, the candidate PS-RNTIs within the DRX cycle are obtained. That is, PS-rntiNumOfEachTdrx candidate PS-RNTIs are configured for each DRX cycle.

[0062] In some implementations, the candidate PS-RNTI transmission timing is obtained based on the DRX cycle and the DCI2-6 transmission cycle configured for the DRX cycle. The number of candidate PS-RNTI transmission timings within any DRX cycle can be obtained using the following formula:

[0063] M = Tdrx / TpdcchDciSend

[0064] where M is the number of candidate PS-RNTI transmission timings within any DRX cycle, Tdrx is the duration of any DRX cycle, and TpdcchDciSend is the duration of the DCI2-6 transmission cycle configured by OAM. Optionally, the duration of the DCI2-6 transmission cycle can take the maximum time length detected by the terminal device specified in the protocol. In the embodiments of the present disclosure, the value range of TpdcchDciSend is 10 ms to 15 ms.

[0065] S402. Obtain the basic PS-RNTI according to the candidate PS-RNTI, and obtain the basic PS-RNTI transmission timing according to the candidate PS-RNTI transmission timing.

[0066] Such as Figure 5As shown, based on the hierarchy to which various resources in the DRX cycle belong, the basic PS-RNTI is obtained according to the candidate PS-RNTI, and the basic PS-RNTI transmission timing is obtained according to the candidate PS-RNTI transmission timing.

[0067] Optionally, the occupancy status of each candidate PS-RNTI is initialized to idle, and the basic PS-RNTI is obtained. That is to say, PS-rntiNumOfEachTdrx basic PS-RNTIs are allocated for each DRX cycle. Similarly, for each candidate PS-RNTI transmission timing, it is initialized, and the basic PS-RNTI transmission timing is obtained.

[0068] The present disclosure hierarchically organizes and maintains DCP resources, obtains the basic PS-RNTI and the basic PS-RNTI transmission timing, which can support relatively more flexible power saving based on service changes, provides a reference for realizing the synchronization and coordination of network devices and terminal devices, configures the DCP resources in the energy saving indication function process, and improves the flexibility of power saving.

[0069] In some implementations, based on the DCI2-6 length configured for the DRX cycle, the candidate DCI2-6Position corresponding to the DRX cycle is obtained. That is to say, SizeDci2-6 candidate DCI2-6 Positions are configured. In any DRX cycle, for j ∈ [0, M - 1] and k ∈ [0, SizeDci2-6 - 1], the candidate Dci2-6 Position[j][k] is initialized to 0, and for other k ∈ [SizeDci2-6, L - 1], the candidate Dci2-6 Position[j][k] is initialized to an invalid value, thereby obtaining the basic DCI2-6 Position. As Figure 5 shown, j and k represent that the basic Dci2-6 Position[j][k] is the kth Dci2-6 Position in the basic PS-RNTI[j], and the basic PS-RNTI[j] represents the jth PS-RNTI of the basic PS-RNTI in the current basic PS-RNTI transmission timing.

[0070] Figure 6 This is a flowchart of a method for configuring DCP resources of a PDCCH provided by an embodiment of the present disclosure. Figure 7 This is a schematic diagram of a method for configuring DCP resources of a PDCCH provided by an embodiment of the present disclosure. As Figure 6 、 Figure 7 shown, based on the above embodiments, the method includes the following steps:

[0071] S601. Obtain candidate detection range points and candidate transmission time slots for any DCI2-6 transmission period within the DRX period.

[0072] The candidate detection range points include a first detection range point and a second detection range point. The process of obtaining the candidate detection range points includes:

[0073] 1. Obtain the first detection range point based on the DRX period offset, the demodulated DCI2-6 reported by the terminal device, the minimum parsing processing time corresponding to the demodulated DCI2-6, and the duration of the DRX period.

[0074] Obtain the DRX period offset in the DRX resources configured for the end user, the demodulated DCI2-6 reported by the terminal device, the minimum parsing processing time corresponding to the demodulated DCI2-6, and the duration of the DRX period. Use the following formula to obtain the first detection range point:

[0075] PS offsetMin =mod{(DRX offset –Minimum offset +Tdrx), Tdrx}

[0076] where mod{...} is the modulo operation, PS offsetMin is the first detection range point of the current DCI2-6 transmission period, DRX offset is the DRX period offset, Minimum offset is the minimum parsing processing time corresponding to the demodulated DCI2-6 reported by the terminal device, and Tdrx is the duration of the DRX period. Optionally, Tdrx takes the duration of the long DRX period.

[0077] 2. Obtain the second detection range point based on the maximum value of the PS-RNTI transmission timing range, the duration of the DRX period, and the DRX period offset, where the second detection range point is earlier than the first detection range point.

[0078] Obtain the maximum value of the PS-RNTI transmission timing range in the DRX resources configured for the end user. Use the following formula to obtain the second detection range point:

[0079] PS offsetMax =mod{(DRX offset -PS offsetMaxRange +Tdrx), Tdrx}

[0080] where PS offsetMax is the second detection range point of the current DCI2-6 transmission period, PS offsetMaxRangeThe value obtained by converting the product of the maximum value 120 in the PS-offset range (1, 2, 3, ..., 120) defined for the protocol specification and 0.125 ms into time slots, i.e., the value obtained by converting 15 ms into time slots according to the subcarrier spacing (SCS). For example, when the SCS is 30 Khz, PS offsetMaxRange is 30 time slots.

[0081] In the embodiments of the present disclosure, PS offsetMax is the maximum detection range point of the PS-offset before the activation period based on DRX defined by the standard, and PS offsetMin is the minimum detection range point after removing the Minimum based on DRX defined by the standard before the activation period. offset

[0082] The candidate transmission time slots include a first transmission time slot and a second transmission time slot. The process of obtaining the candidate transmission time slots includes:

[0083] 1. Confirm the second PS-RNTI transmission opportunity from the basic PS-RNTI transmission opportunities based on the second detection range point and the number of time slots in each DCI2-6 transmission period.

[0084] Obtain the number of time slots in each DCI2-6 transmission period that can be configured by OAM, and then use the following formula to obtain the second PS-RNTI transmission opportunity:

[0085]

[0086] where X is the second PS-RNTI transmission opportunity, SlotsNumInOneSendPeriod is the number of time slots in each DCI2-6 transmission period, and the mathematical symbol represents rounding down.

[0087] 2. Confirm the first PS-RNTI transmission opportunity from the basic PS-RNTI transmission opportunities based on the first detection range point and the number of time slots in each DCI2-6 transmission period.

[0088] Use the following formula to obtain the first PS-RNTI transmission opportunity:

[0089]

[0090] where Y is the first PS-RNTI transmission opportunity. In the embodiments of the present disclosure, X is the transmission opportunity corresponding to the earliest point of the DCI2-6 transmission period, and Y is the transmission opportunity corresponding to the latest point of the DCI2-6 transmission period.

[0091] ​3. Based on the first PS-RNTI transmission occasion, the number of time slots within each DCI2-6 transmission period, and the time slot number corresponding to the target format for transmitting DCI, i.e., the time slot number for transmitting DCI2-6, obtain the first transmission time slot.

[0092] Obtain the time slot number for transmitting DCI2-6 within each detection configured by OAM, and use the following formula to obtain the first transmission time slot:

[0093] B = (Y × SlotsNumInOneSendPeriod) + m

[0094] Where B is the first transmission time slot, and m is the time slot number for transmitting DCI2-6 within each DCI2-6 transmission period. Optionally, m can have multiple values. For example, if the time slot numbers for transmitting DCI2-6 within the DCI2-6 transmission period are {2, 3}, then m takes the values 2 and 3 respectively for the calculation of the first transmission time slot.

[0095] 4. Based on the second PS-RNTI transmission occasion, the number of time slots within each DCI2-6 transmission period, and the time slot number for transmitting DCI2-6 within each detection, obtain the second transmission time slot, where the second transmission time slot is earlier than the first transmission time slot.

[0096] A = (X × SlotsNumInOneSendPeriod) + m

[0097] Where A is the second transmission time slot.

[0098] S602. Based on the candidate detection range points and the candidate transmission time slots, confirm the target PS-offset and the target PS-RNTI transmission occasion.

[0099] 1. If the second detection range point is less than or equal to the second transmission time slot, and the first detection range point is greater than or equal to the first transmission time slot, determine that the target PS-RNTI transmission occasion is the first PS-RNTI transmission occasion and the second PS-RNTI transmission occasion, and the target PS-offset is the first transmission time slot and the second transmission time slot.

[0100] In the embodiments of the present disclosure, if PS offsetMax <= A and PS offsetMin >= B, it means that within the DCI2-6 transmission period, there are two selectable DCI2-6 transmission points. At this time, the target PS-offset set PS-offset AllocSet {} is {B, A}, and the target PS-RNTI transmission occasion set SendOccassionSet {} is {Y, X}.

[0101] 2. If the second detection range point is less than or equal to the second transmission time slot, and the first detection range point is less than the first transmission time slot, determine that the target PS-RNTI transmission occasion is the second PS-RNTI transmission occasion, and the target PS-offset is the second transmission time slot.

[0102] In the embodiments of the present disclosure, if PS offsetMax <= A and PS offsetMin < B, it indicates that there is one selectable DCI2-6 transmission point within the DCI2-6 transmission period. At this time, the target PS-offset set PS-offset AllocSet {} is {A}, and the target PS-RNTI transmission occasion set SendOccassionSet{} is {X}.

[0103] 3. If the second detection range point is greater than the second transmission time slot, and the first detection range point is greater than or equal to the first transmission time slot, determine that the target PS-RNTI transmission occasion is the first PS-RNTI transmission occasion, and the target PS-offset is the first transmission time slot.

[0104] In the embodiments of the present disclosure, if PS offsetMax > A and PS offsetMin >= B, it indicates that there is one selectable DCI2-6 transmission point within the DCI2-6 transmission period. At this time, the target PS-offset set PS-offset AllocSet {} is {B}, and the target PS-RNTI transmission occasion set SendOccassionSet{} is {Y}.

[0105] Optionally, if there are multiple target PS-RNTI transmission occasions, the configuration is preferentially performed from the latest target transmission occasion.

[0106] The present disclosure hierarchically manages and maintains DCP resources, dynamically allocates and adjusts the configuration information of DCP resources, which can support relatively more flexible power saving based on service changes, provides a reference for synchronizing and coordinating network devices and terminal devices, configures DCP resources in the energy saving indication function process, and improves the flexibility of power saving.

[0107] Figure 8 It is a flowchart of a method for configuring DCP resources of PDCCH provided by an embodiment of the present disclosure. As Figure 8 shown, on the basis of the above embodiments, the determination process of the target DCI2-6 Position includes the following steps:

[0108] S801. Determine a base wake-up indication bit that meets a preset condition from the base wake-up indication bits included in the target PS-RNTI transmission occasion as the target wake-up indication bit.

[0109] Optionally, the preset condition is that the target PS-RNTI transmission opportunity is not occupied at the base DCI2-6Position in N consecutive positions, and the base PS-RNTI corresponding to the base Dci2-6 Position is a valid value, where N is the length of DCI2-6 to be allocated, that is, the number of bits of DCI2-6 to be allocated. For the DRX energy-saving adaptive function, this value is taken as 1. For the carrier aggregation (CA) sleep function, this value is the number of groups of one or more secondary cells (Scells). That is to say, N is a positive integer obtained based on actual needs. Optionally, set the occupancy flag 1 for the target DCI2-6 Position.

[0110] For example, according to the configuration information, the target DCI2-6 Position is allocated as the base Dci2-6 Position[j][k] at the i-th base PS-RNTI transmission opportunity DciSendOccassion[i] in the current DRX cycle of the terminal device. Then, the target PS-RNTI corresponding to the target DCI2-6 Position is the base PS-RNTI[j], the target PS-RNTI transmission opportunity corresponding to the base Dci2-6Position[j][k] is DciSendOccassion[i], and the target PS-offset corresponding to the base Dci2-6Position[j][k] = mod{(Drx offset -PS-offset AllocSet {} + Tdrx), Tdrx} / 2u / 0.125ms, where PS-offset AllocSet {} is the set of target PS-offsets corresponding to DciSendOccassion[i], and u is the mapping value of SCS. In the embodiments of the present disclosure, when SCS is 15, 30, 60, and 120 kHz respectively, the corresponding u values are 0, 1, 2, and 3, 4 respectively.

[0111] It should be noted that if multiple PS-offsets that meet the conditions are calculated, one that is closer to the DRX active period and does not conflict with the measurement gap GAP at all is selected.

[0112] In some implementations, if there is no DCI2-6 Position that meets the preset conditions among the DCI2-6 Positions included in the target PS-RNTI transmission opportunity, the DRX adaptive energy-saving parameters are not configured for this terminal device.

[0113] The present disclosure hierarchizes and maintains DCP resources, dynamically allocates and adjusts the configuration information of DCP resources, can support relatively more flexible power saving based on service changes, provides a reference for realizing the synchronous coordination of network devices and terminal devices, configures the DCP resources in the energy saving indication function process, and improves the flexibility of power saving.

[0114] Take Figure 7 the terminal device UE2 in offset as an example for illustration. The SCS is 30 kHz, Tdrx = 160 ms, Drx offset = 0 ms, Minimum offsetMax = 6 slot, m = 12 slot. Then, based on the method in the above factual example, PS offsetMin = 290 slot, PS AllocSet = 314 slot, A = 292 slot, B = 312 slot, X = 14, Y = 15. Then the selected PS-offset

[0115] Take Figure 7 the terminal device UE1 in offset as an example for illustration. The SCS is 30 kHz, Tdrx = 160 ms, Drx offset = 16 ms, Minimum offsetMax = 6 slot, m = 12 slot. Then, based on the method in the above factual example, PS offsetMin = 2 slot, PS AllocSetIf it is {12}, then the DciSendOccassion[i] corresponding to the basic Dci2-6 Position[j][k] is {0}, the target PS-offset corresponding to the basic Dci2-6 Position[j][k] is 80. Confirm whether DciSendOccassion[i] has a basic Dci2-6 Position[j][k] that meets the preset conditions. If it meets the preset conditions, select this PS-offset; otherwise, do not configure the DRX adaptive energy-saving parameters.

[0116] Figure 9 It is a schematic flowchart of a method for configuring DCP resources of a PDCCH provided by an embodiment of the present disclosure. As Figure 9 shown, based on the above embodiment, the method includes the following steps:

[0117] S901, determine the basic PS-RNTI, the basic PS-RNTI transmission occasion, and the basic wake-up indication bit corresponding to the target format of DCI within the DRX cycle.

[0118] S902, based on the basic PS-RNTI, the basic PS-RNTI transmission occasion, and the basic wake-up indication bit, obtain the configuration information of the DCP resources, and the configuration information is used to instruct the terminal device to save power.

[0119] For the introduction of step S901 and step S902, reference can be made to the relevant content of the above embodiment, which will not be elaborated here.

[0120] S903, if the number of DRX terminal devices increases, update the basic PS-RNTI, the basic PS-RNTI transmission occasion, the basic wake-up indication bit, and the target PS-offset within the DRX cycle to update the configuration information of the DCP resources.

[0121] When the number of DRX terminal devices increases, for the incremental DRX terminal devices, update the basic PS-RNTI, the basic PS-RNTI transmission occasion, the basic DCI2-6 Position, and the target PS-offset within the DRX cycle according to the method of the above embodiment, and then update the configuration information of the DCP resources to implement the configuration of the DCP resources.

[0122] The present disclosure hierarchically manages and maintains the DCP resources, dynamically allocates and adjusts the configuration information of the DCP resources, which can support relatively more flexible power saving based on service changes, provides a reference for realizing the synchronization and coordination between network devices and terminal devices, configures the DCP resources in the energy-saving indication function process, and improves the flexibility of power saving. When the number of DRX terminal devices increases, update the configuration information of the DCP resources to dynamically adapt to the needs of terminal devices and meet the DRX cycle requirements of different services.

[0123] In some implementations, when the types of DRX cycles increase, the new TDRX cycle is dynamically and proportionally allocated according to the relevant content of the above embodiments. That is to say, the configuration information of the DCP resources corresponding to the incremental DRX cycles is configured.

[0124] In some implementations, when the DRX cycle changes or when there is an increase in the number of bits required for Dci2-6 positions, the configuration information of the DCP resources is allocated and adjusted according to the method of the above embodiments. It is preferentially allocated after the current target Dci2-6Position of the terminal device. When there are multiple target PS-RNTI transmission opportunities, if the preset conditions are not met, it can be allocated at the Dci2-6Position under other target PS-RNTI transmission opportunities of this terminal device. When the number of Dci2-6Positions decreases, since it does not affect the air interface configuration, the configuration information of the DCP resources is not allocated and adjusted. The present disclosure can dynamically adapt to the increasing capacity requirements of terminal devices and meet the DRX cycle requirements of different services.
