Technical Field

[0001] Embodiments of the present application relate to the field of wireless communications, and more specifically, to a discontinuous reception method, terminal equipment, and network equipment. Background Art

[0002] In order to solve the power consumption problem of terminal devices and ensure that the terminal can monitor the data sent by the network device in time, the discontinuous reception (DRX) method can be used to meet the needs of low power consumption and signal monitoring as much as possible. The DRX method allows the terminal device to periodically enter the sleep mode (sleep mode) in certain time periods without monitoring the physical downlink control channel (PDCCH), and wake up from the sleep mode (wake up) when it needs to monitor the PDCCH, so as to achieve the purpose of power saving.

[0003] In the Long Term Evolution (LTE) system, if the terminal device is configured with the DRX function, the network device will configure a set of DRX parameters for the terminal device, such as the On Duration Time, Inactivity Time, DRX short cycle, DRX long cycle and other parameters. The terminal device can determine when to monitor the PDCCH based on these DRX parameters. However, the 5G system supports multiple basic parameter sets (numerology), such as supporting multiple different subcarrier intervals, which may cause the time and frequency resources used by the terminal device to monitor the PDCCH to change continuously, and the original DRX method cannot meet the needs of the terminal device to monitor data. Therefore, it is urgently necessary to use a more flexible DRX method to meet the low power consumption requirements and signal monitoring requirements of terminal devices when transmitting data based on different basic parameter sets. Summary of the invention

[0004] The embodiments of the present application provide a discontinuous reception method, terminal device and network device, which can meet the low power consumption requirements and signal monitoring requirements of the terminal device when performing data transmission based on different basic parameter sets.

[0006] Therefore, the terminal device jointly determines the target time-frequency resources for monitoring the control channel based on multiple sets of DRX parameters, so that the terminal device can also meet the low power consumption requirements and signal monitoring requirements when transmitting data based on different basic parameter sets.

[0007] Optionally, the terminal device determines the target time-frequency resources for monitoring the control channel based on the at least one set of DRX parameters, including: the terminal device determines at least one set of time-frequency resources for monitoring the control channel based on the at least one set of DRX parameters, and the at least one set of DRX parameters corresponds one-to-one to the at least one set of time-frequency resources; the terminal device determines the target time-frequency resources based on the at least one set of time-frequency resources, wherein the target time-frequency resources include the at least one set of time-frequency resources.

[0009] That is to say, when the time domain resource ranges of different time domain resources in different time domain resource sets completely overlap, the smaller time domain resource range should be adjusted to be equal to the larger domain resource range, that is, the time domain resource range shall be based on the larger time domain resource range.

[0010] Optionally, each set of DRX parameters in the at least one set of DRX parameters includes at least one of the following parameters: start time, inactive time, retransmission time, DRX short cycle, DRX long cycle and frequency domain monitoring range, wherein the frequency domain monitoring range represents the range of frequency domain resources used to monitor the control channel.

[0011] In this embodiment, the terminal device may not monitor the control channel over the entire frequency band, but only monitor the control channel within a preset frequency domain resource range. Therefore, it can flexibly adapt to signal transmission based on different basic parameter sets such as different subcarrier spacings, while reducing the monitoring complexity of the terminal device.

[0019] Optionally, in the at least one time-frequency resource set, if the time domain resource range of the first time-frequency resource in the first time-frequency resource set includes the time domain resource range of the second time-frequency resource in the second time-frequency resource set, the time domain resource range of the second time-frequency resource is adjusted to the time domain resource range of the first time-frequency resource.

[0020] That is to say, when the time domain resource ranges of different time domain resources in different time domain resource sets completely overlap, the smaller time domain resource range should be adjusted to be equal to the larger domain resource range, that is, the time domain resource range shall be based on the larger time domain resource range.

[0021] Optionally, each set of DRX parameters in the at least one set of DRX parameters includes at least one of the following parameters: start time, inactive time, retransmission time, DRX short cycle, DRX long cycle and frequency domain monitoring range, wherein the frequency domain monitoring range represents the range of frequency domain resources used to monitor the control channel.

[0022] In this embodiment, the terminal device may not monitor the control channel over the entire frequency band, but only monitor the control channel within a preset frequency domain resource range. Therefore, it can flexibly adapt to signal transmission based on different basic parameter sets such as different subcarrier spacings, while reducing the monitoring complexity of the terminal device.

[0057] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0058] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Global System of Mobile Communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), and future 5G communication systems, etc.

[0059] The present application describes various embodiments in conjunction with terminal devices. Terminal devices may also refer to user equipment (UE), access terminals, user units, user stations, mobile stations, mobile stations, remote stations, remote terminals, mobile devices, user terminals, terminals, wireless communication devices, user agents, or user devices. The access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network, or a terminal device in a future evolving land public mobile communication network (PLMN) network, etc.

[0060] The present application describes various embodiments in conjunction with a network device. The network device may be a device for communicating with a terminal device, for example, a base station (Base Transceiver Station, BTS) in a GSM system or CDMA, a base station (NodeB, NB) in a WCDMA system, or an evolved base station (EvolutionalNode B, eNB or eNodeB) in an LTE system, or the network device may be a relay station, an access point, an in-vehicle device, a wearable device, a network side device in a future 5G network, or a network side device in a future evolved PLMN network, etc.

[0061] Figure 1 It is a schematic diagram of an application scenario of an embodiment of the present application. Figure 1 The communication system in the embodiment may include a network device 10 and a terminal device 20. The network device 10 is used to provide communication services for the terminal device 20 and access the core network. The terminal device 20 can access the network by searching for synchronization signals, broadcast signals, etc. sent by the network device 10, thereby communicating with the network. Figure 1 The arrows shown in may represent uplink / downlink transmissions performed via a cellular link between the terminal device 20 and the network device 10 .

[0062] The network in the embodiment of the present application may refer to a public land mobile network (PLMN) or a device to device (D2D) network or a machine to machine / man (M2M) network or other networks. Figure 1 This is just a simplified diagram for example. The network may also include other terminal devices. Figure 1 Not drawn in.

[0063] Due to the discontinuity of data transmission, it is impossible for the terminal device to monitor the data scheduling instructions of the network device, that is, the control channel in LTE, such as PDCCH, all the time, otherwise the power consumption will be too large. In order to reduce the power consumption of the terminal device and ensure that the terminal can monitor the data sent by the network device in time, the DRX method can be used to balance the power consumption and signal monitoring. The network device can configure the terminal device to "wake up" or DRX ON within the time predicted by the network device, and the terminal device monitors PDCCH. The network device can also configure the terminal device to "sleep" or DRX OFF within the time predicted by the network device, and the terminal device does not monitor PDCCH during this time. In this way, if the network device has data to send to the terminal device, the network device can schedule the terminal device to wake up and monitor PDCCH during the DRX ON time of the terminal device, and reduce the power consumption of the terminal device during the DRX OFF time. According to the different Radio Resource Control (RRC) modes adopted by the terminal device, such as RRC-CONNECTED mode or RRC-IDLE mode, DRX has different operation methods. The DRX method of the embodiment of the present application is only for DRX in RRC-CONNECTED mode (referred to as C-DRX for short). In C-DRX mode, the network device manages the DRX ON and DRX OFF states of the terminal device by configuring a series of timers.

[0064] like Figure 2 The schematic diagram of using DRX mode to monitor PDCCH is shown in FIG. 1 During this time, the terminal device is in an awake state and can monitor control channels such as PDCCH. 2 During this period, the terminal device is in sleep mode and does not monitor PDCCH, which can reduce power consumption. Figure 2 It can be seen that T 2 The longer the terminal device, the lower the power consumption.

[0065] If the terminal device is configured with the DRX function, the network device will configure a set of DRX parameters for the terminal device, such as on duration time, inactivity time, short DRX cycle, long DRX cycle, etc. The terminal device can determine when to monitor the PDCCH based on these DRX parameters, that is, the terminal device can determine the T according to these parameters. 1 and T 2 size.

[0066] Here is the T 1The time period can be determined by the on time, which can be called On DurationTime. This period is the time when the terminal device monitors the downlink PDCCH. The terminal device is in an awake state during this period. The T2 time period can also be called Opportunity for DRX. During this period, the terminal device can enter the sleep state instead of monitoring the PDCCH in order to save power. T1 and T2 make up a DRX cycle, which can be a short DRX cycle or a long DRX cycle. Network equipment can configure short cycles or long cycles for terminal devices according to different business scenarios. If both short cycles and long cycles are configured, if the downlink PDCCH is not detected within a certain period of time, the terminal device enters the long DRX cycle from the short DRX cycle.

[0067] If the terminal device successfully decodes the PDCCH during the On Duration Time, the terminal device may start a DRX-Inactivity Timer and continue to monitor the PDCCH during the duration of the timer, ie, the Inactivity Time, until the DRX-Inactivity Timer times out.

[0068] However, in the 5G system, multiple basic parameter sets can be used for data transmission, such as using different subcarrier intervals to transmit data, which may cause the time and frequency resources for the terminal device to monitor the PDCCH to change continuously, and the original DRX method cannot meet the needs of the terminal device to monitor data. Therefore, a more flexible method is urgently needed to meet the low power consumption and signal monitoring needs of the terminal device when transmitting data based on different basic parameter sets.

[0069] An embodiment of the present application proposes to jointly determine the target time-frequency resources for monitoring the control channel based on multiple sets of DRX parameters, so that the terminal device can also meet the low power consumption requirements and signal monitoring requirements when performing data transmission based on different basic parameter sets.

[0070] Figure 3 3 is a schematic flow chart of a method 300 for discontinuous reception according to an embodiment of the present application. The method may be executed by a terminal device, which may be, for example, Figure 1 The terminal device 20 shown in FIG. Figure 3 As shown, the discontinuous reception method includes:

[0071] In 310, the terminal device determines at least one set of DRX parameters.

[0072] Specifically, the network device may configure one or more sets of DRX parameters for the terminal device. When the network device configures multiple sets of DRX parameters for the terminal device, the terminal device may determine at least one set of DRX parameters from the multiple sets of DRX parameters.

[0073] Optionally, each set of DRX parameters in the at least one set of DRX parameters includes at least one of the following parameters: on duration time, inactivity time, retransmission time, short DRX cycle, long DRX cycle and frequency domain monitoring range (Frequency Monitoring Range, FMR), wherein the frequency domain monitoring range represents the range of frequency domain resources used to monitor the control channel.

[0074] Specifically, the DRX parameters in each set of DRX parameters may determine a set of time-frequency resources used by the terminal device to monitor the control channel, for example Figure 4 FIG. 4 is a schematic diagram showing time-frequency resources for monitoring a control channel determined by a set of DRX parameters. Figure 4 The terminal device monitors the control channel at the time-frequency resource position represented by the shaded part, and the time-frequency resources represented by each shaded area are distributed according to a certain DRX cycle, which can be a DRX short cycle or a DRX long cycle. Figure 4 Only 3 cycles are shown.

[0075] In this embodiment, the terminal device may not monitor the control channel over the entire frequency band, but only monitor the control channel within a preset frequency domain resource range. Therefore, it can flexibly adapt to signal transmission based on different basic parameter sets such as different subcarrier spacings, while reducing the monitoring complexity of the terminal device.

[0076] Optionally, each set of DRX parameters includes one or more frequency domain monitoring ranges, and the multiple frequency domain monitoring ranges are discontinuous in the frequency domain.

[0077] Figure 4 Only one FMR is shown, but each set of DRX parameters may include one or more FMR parameters. Further, if a set of DRX parameters includes multiple FMR parameters, the positions of the frequency domain resources indicated by the multiple FMR parameters may be discontinuous in the frequency domain, and the sizes of the frequency domain resources indicated by the multiple FMR parameters may also be the same or different. This application does not make any limitation to this.

[0078] In an embodiment of the present application, the terminal device may determine the at least one set of DRX parameters in any one of the following two ways.

[0079] Method 1

[0080] Optionally, the terminal device determines the at least one set of DRX parameters, including: the terminal device determines the at least one set of DRX parameters corresponding to the at least one basic parameter set based on the at least one basic parameter set used and the correspondence between the multiple basic parameter sets and the multiple sets of DRX parameters.

[0081] Specifically, each set of DRX parameters can determine a set of time-frequency resources used by the terminal device to monitor the control channel to meet the needs of the terminal device for DRX transmission based on a certain basic parameter set. However, since the terminal device in the 5G system can use multiple basic parameter sets to transmit control signals or data with the network device, the terminal device can determine at least one set of DRX parameters corresponding to the at least one basic parameter set based on the at least one basic parameter set used by it, and the correspondence between the multiple basic parameter sets and the multiple sets of DRX parameters, thereby jointly determining the target time-frequency resources ultimately used to monitor the control channel based on the at least one set of DRX parameters.

[0082] It should be understood that the correspondence between multiple basic parameter sets and multiple sets of DRX parameters can be presented, for example, in the form of tables, formulas, images, etc., and in the correspondence, one basic parameter set can correspond to one or more sets of DRX parameters, and one set of DRX parameters can also correspond to one or more basic parameter sets. In other words, the terminal device can determine at least one set of DRX parameters corresponding to the at least one basic parameter set by searching a preset table including the correspondence between multiple basic parameter sets and multiple sets of DRX parameters; or the terminal device can also calculate the identifier or number of at least one set of DRX parameters corresponding to the at least one basic parameter set by a preset formula and relevant parameter information of the basic parameter set. This application does not limit this.

[0083] Method 2

[0084] Optionally, the terminal device determines at least one set of DRX parameters, including: the terminal device receives indication information sent by a network device, where the indication information is used to indicate the at least one set of DRX parameters.

[0085] Optionally, the indication information is a media access control (Media Access Control, MAC) control element (Control Element, CE) or downlink control information (Download Control Information, DCI).

[0086] In 320, the terminal device determines the target time-frequency resources for sending the control channel according to the at least one set of DRX parameters.

[0087] Specifically, each set of DRX parameters may determine, for example Figure 3 As shown in a set of time-frequency resources for monitoring the control channel, after the terminal device selects at least one set of DRX parameters, it can determine at least one set of time-frequency resources for monitoring the control channel corresponding to the at least one set of DRX parameters, and determine the target time-frequency resources ultimately used to monitor the control channel based on the at least one set of time-frequency resources.

[0088] In the embodiment of the present application, the monitoring control channel may also be referred to as a monitoring control channel region, a monitoring control channel subframe, etc. The control channel region includes at least one control channel, such as at least one PDCCH.

[0089] Alternatively, if Figure 5 As shown, 320 may include 321 and 322, and 321 and 322 describe a possible implementation method of how the terminal device determines the target time-frequency resources according to the at least one set of DRX parameters.

[0090] In 321, the terminal device determines at least one set of time-frequency resources for monitoring the control channel according to the at least one set of DRX parameters, and the at least one set of DRX parameters corresponds one-to-one to the at least one set of time-frequency resources.

[0091] In 322, the terminal device determines the target time-frequency resource based on the at least one time-frequency resource set, wherein the target time-frequency resource includes the at least one time-frequency resource set.

[0092] Specifically, after the terminal device selects at least one set of DRX parameters, it determines at least one set of time-frequency resources for monitoring the control channel according to the at least one set of DRX parameters, and determines the target time-frequency resources for monitoring the control channel according to the at least one set of time-frequency resources. The target time-frequency resources include the at least one time-frequency resource. In other words, the target time-frequency resources are the union of the at least one time-frequency resources.

[0093] For example Figure 6(a) to Figure 6(c) FIG6(a) shows a first set of time-frequency resources for monitoring a control channel determined by a terminal device according to a first set of DRX parameters, wherein the first set of DRX parameters includes a first on time T 11 , the first frequency domain monitoring range FMR1, DRX cycle T 21 ; FIG. 6( b) shows a second set of time-frequency resources for monitoring a control channel determined by the terminal device according to a second set of DRX parameters, wherein the second set of DRX parameters includes a first on time T 12 , first frequency domain monitoring range FMR2, DRX cycle T 22 Among them, T 11<T 12 , FMR1=FMR2, T 21 <T 22 FIG6(c) shows the target time-frequency resources determined by the terminal device based on the first time-frequency resource set and the second time-frequency resource set. It can be seen that the target time-frequency resources include the first time-frequency resource set and the second time-frequency resource set.

[0094] Another example Figure 7(a) to Figure 7(c) FIG7(a) shows a first set of time-frequency resources for monitoring a control channel determined by a terminal device according to a first set of DRX parameters, wherein the first set of DRX parameters includes a first on time T 11 , the first frequency domain monitoring range FMR1, DRX cycle T 21 ; FIG. 7( b) shows a second set of time-frequency resources for monitoring a control channel determined by the terminal device according to a second set of DRX parameters, wherein the second set of DRX parameters includes a first on time T 12 , first frequency domain monitoring range FMR2, DRX cycle T 22 Among them, T 11 <T 12 , FMR1≠FMR2 (the size and position of the frequency domain resources represented by FMR1 and FMR2 are different), T 21 <T 22 FIG7(c) shows the target time-frequency resources determined by the terminal device based on the first time-frequency resource set and the second time-frequency resource set. It can be seen that the target time-frequency resources include the first time-frequency resource set and the second time-frequency resource set.

[0095] Further, optionally, in the at least one time-frequency resource set, if the time domain resource range of the first time-frequency resource in the first time-frequency resource set includes the time domain resource range of the second time-frequency resource in the second time-frequency resource set, then the time domain resource range of the second time-frequency resource is adjusted to the time domain resource range of the first time-frequency resource.

[0096] That is to say, when the time domain resource ranges of different time domain resources in different time domain resource sets completely overlap, the smaller time domain resource range should be adjusted to be equal to the larger domain resource range, that is, the time domain resource range shall be based on the larger time domain resource range.

[0097] For example Figure 6(a) to Figure 6(c) As shown in FIG. 6( a ), when the time-frequency resource A in FIG. 6( a ) overlaps with the time-frequency resource B in FIG. 6( b ), the time-frequency resource C in FIG. 6( c ) includes the time-frequency resource A (the frequency domain range is equal to FMR1, and the time domain range is also equal to T 12 ) and time-frequency resource B (frequency domain range equal to FMR2, time domain range equal to T 12), where the time domain resource range of the time-frequency resource C is equal to the larger T 12 .

[0098] When the time domain resource ranges of different time-frequency resources in different time-frequency resource sets do not overlap or partially overlap, the time domain resource ranges of these different time-frequency resources included in the target time-frequency resources remain unchanged. Figure 7(a) to Figure 7(c) As shown in FIG. 7( a ), the time-frequency resource A in FIG. 7( a ) does not overlap with the time-frequency resource B in FIG. 6( b ), and the time-frequency resource C in FIG. 6( c ) includes the time-frequency resource A (the frequency domain range is equal to FMR1, and the time domain range is equal to T 11 ) and time-frequency resource B (frequency domain range equal to FMR2, time domain range equal to T 12 ).

[0099] Another example Figure 8(a) to Figure 8(c) FIG8(a) shows a first set of time-frequency resources for monitoring a control channel determined by a terminal device according to a first set of DRX parameters. The first set of DRX parameters includes a first on time T 11 , the first frequency domain monitoring range FMR1, DRX cycle T 21 8(b) shows a second set of time-frequency resources for monitoring a control channel determined by the terminal device according to a second set of DRX parameters, wherein the second set of DRX parameters includes a first on time T 12 , first frequency domain monitoring range FMR2, DRX cycle T 22 Among them, T 11 <T 12 , FMR1≠FMR2 (the frequency domain resources represented by FMR1 and FMR2 are of the same size but in different locations), T 21 <T 22 FIG8(c) shows the target time-frequency resources determined by the terminal device according to the first time-frequency resource set and the second time-frequency resource set. It can be seen that when the time-frequency resource A in FIG8(a) overlaps with the time-frequency resource B in FIG8(b), the time-frequency resource C in FIG8(c) includes the time-frequency resource A (the frequency domain range is equal to FMR1 and the time domain range is also equal to T 12 ) and time-frequency resource B (frequency domain range equal to FMR2, time domain range equal to T 12 ), where the time domain resource range of the time-frequency resource C is equal to the larger T 12 .

[0100] In 330, the terminal device monitors the control channel on the target time-frequency resource.

[0101] The terminal device monitors the control channel such as PDCCH on the target time-frequency resource, and does not monitor the control channel during the rest of the time, thereby achieving the purpose of power saving.

[0102] According to the DRX method described in the embodiment of the present application, the terminal device jointly determines the target time-frequency resources for monitoring the control channel based on multiple sets of DRX parameters, so that the terminal device can also meet the low power consumption requirements and signal monitoring requirements when performing data transmission based on different basic parameter sets.

[0103] Fig. 9 900 is a schematic flow chart of a discontinuous reception method according to an embodiment of the present application. The method may be executed by a network device, which may be, for example, Figure 1 The network device 10 shown in FIG. Fig. 9 As shown, the discontinuous reception method includes:

[0104] In 910, the network device determines at least one set of DRX parameters.

[0105] Optionally, each set of DRX parameters in the at least one set of DRX parameters includes at least one of the following parameters: on duration time, inactivity time, retransmission time, short DRX cycle, long DRX cycle and frequency domain monitoring range (Frequency Monitoring Range, FMR), wherein the frequency domain monitoring range represents the range of frequency domain resources used to monitor the control channel.

[0106] Optionally, each set of DRX parameters includes one or more frequency domain monitoring ranges, and the multiple frequency domain monitoring ranges are discontinuous in the frequency domain.

[0107] In 920, the network device determines a target time-frequency resource for sending a control channel according to the at least one set of DRX parameters.

[0108] Optionally, the network device determines the target time-frequency resources for sending the control channel based on the at least one set of DRX parameters, including: the network device determines at least one set of time-frequency resources for sending the control channel based on the at least one set of DRX parameters, and the at least one set of DRX parameters corresponds one-to-one to the at least one set of time-frequency resources; the network device determines the target time-frequency resources based on the at least one set of time-frequency resources, wherein the target time-frequency resources include the at least one set of time-frequency resources.

[0109] Further, optionally, in the at least one time-frequency resource set, if the time domain resource range of the first time-frequency resource in the first time-frequency resource set includes the time domain resource range of the second time-frequency resource in the second time-frequency resource set, then the time domain resource range of the second time-frequency resource is adjusted to the time domain resource range of the first time-frequency resource.

[0110] That is to say, when the time domain resource ranges of different time domain resources in different time domain resource sets completely overlap, the smaller time domain resource range should be adjusted to be equal to the larger domain resource range, that is, the time domain resource range shall be based on the larger time domain resource range.

[0111] For example Figure 8(a) to Figure 8(c) FIG8(a) shows a first set of time-frequency resources for monitoring a control channel determined by a terminal device according to a first set of DRX parameters, wherein the first set of DRX parameters includes a first on time T 11 , the first frequency domain monitoring range FMR1, DRX cycle T 21 8(b) shows a second set of time-frequency resources for monitoring a control channel determined by the terminal device according to a second set of DRX parameters, wherein the second set of DRX parameters includes a first on time T 12 , first frequency domain monitoring range FMR2, DRX cycle T 22 Among them, T 11 <T 12 , FMR1=FMR2, T 21 <T 22 FIG8(c) shows the target time-frequency resources determined by the terminal device according to the first time-frequency resource set and the second time-frequency resource set. It can be seen that when the time-frequency resource A in FIG8(a) overlaps with the time-frequency resource B in FIG8(b), the time-frequency resource C in FIG8(c) includes the time-frequency resource A (the frequency domain range is equal to FMR1 and the time domain range is also equal to T 12 ) and time-frequency resource B (frequency domain range equal to FMR2, time domain range equal to T 12 ), where the time domain resource range of the time-frequency resource C is equal to the larger T 12 .

[0112] It should be understood that the process of the network device determining the target time-frequency resource can be specifically referred to in the aforementioned Figure 3 The description of the process of the terminal device determining the target time-frequency resources in is not repeated here for the sake of brevity.

[0113] In 930, the network device sends the control channel to the terminal device on the target time-frequency resource.

[0114] In the DRX method described in the embodiment of the present application, the network device jointly determines the target time-frequency resources for sending the control channel based on multiple sets of DRX parameters, so that the terminal device can correctly monitor the control channel according to the multiple sets of DRX parameters, thereby meeting the low power consumption requirements and signal monitoring requirements when data transmission is based on different basic parameter sets.

[0115] It should be understood that in the various embodiments of the present application, the size of the serial numbers of the above-mentioned processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
