[0046] In order to understand the features and technical content of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The attached drawings are for reference and illustration only, and are not used to limit the embodiments of the present invention.

[0047] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0048] 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, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system or 5G system, etc.

[0049] Exemplarily, the communication system 100 to which the embodiments of the present application are applied can be as Figure 1-1 shown. The communication system 100 may include a network device 110, and the network device 110 may be a device that communicates with a UE 120 (or referred to as a communication terminal device, terminal device). The network device 110 may provide communication coverage for a specific geographical area and may communicate with UEs located within the coverage area. Optionally, the network device 110 may be a network device (Base Transceiver Station, BTS) in a GSM system or a CDMA system, may also be a network device (NodeB, NB) in a WCDMA system, may also be an evolved network device (Evolutional Node B, eNB or eNodeB) in an LTE system, or a radio controller in a Cloud Radio Access Network (CRAN), or the network device may be a mobile switching center, a relay station, an access point, a vehicle-mounted device, a wearable device, a hub, a switch, a bridge, a router, a network-side device in a 5G network, or a network device in a future evolved Public Land Mobile Network (PLMN), etc.

[0050] The communication system 100 further includes at least one UE 120 within the coverage area of the network device 110. As used herein, "UE" includes, but is not limited to, connections via wired lines, such as via the Public Switched Telephone Networks (PSTN), Digital Subscriber Line (DSL), digital cable, direct cable connection; and / or another data connection / network; and / or via a wireless interface, such as for a cellular network, Wireless Local Area Network (WLAN), digital television network such as a DVB-H network, satellite network, AM-FM broadcast transmitter; and / or a device configured to receive / transmit communication signals for another UE; and / or an Internet of Things (IoT) device. A UE configured to communicate via a wireless interface may be referred to as a "wireless communication terminal device", "wireless terminal device" or "mobile terminal device".

[0051] Optionally, Device to Device (D2D) communication may be performed between UEs 120.

[0052] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term " / or" herein merely describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0053] The solution provided by the embodiments of the present invention is applicable to the CA scenario. Specifically:

[0054] In order to be able to provide a greater data transmission rate and enhance the user experience, 5G NR further increases the system bandwidth based on 4G. In 5G NR, for frequency bands below 6 GHz, the maximum bandwidth supported by a single carrier is 100 MHz; for frequency bands above 6 GHz, the maximum bandwidth supported by a single carrier is 400 MHz. Similar to the LTE system, 5G NR also supports the CA technology. For a terminal supporting the CA feature, in addition to having a PCell, the network RRC can also configure one or more SCell for the terminal. The terminal can simultaneously send and receive data on the PCell and one or more activated SCell, thereby enhancing the data transmission rate.

[0055] Among them, the SCell has two states: active and inactive. Only when the SCell is in the active state can the terminal send and receive data on this SCell. For the configured SCell, its initial state is inactive. The activation / deactivation of the SCell can be achieved by at least one of the following two methods: SCell activation / deactivation based on the SCell activation / deactivation MAC CE indication; SCell deactivation based on timer timeout.

[0056] On the other hand, for a large carrier bandwidth, such as 100HMz, the bandwidth that the terminal device needs to use is often very limited. If the terminal is always detecting and measuring over the entire bandwidth, it will pose a great challenge to the terminal power consumption and is not conducive to power saving of the terminal. Therefore, the concept of Bandwidth Part (BWP) is introduced in 5G NR, that is, a part of the continuous bandwidth within the entire large-bandwidth carrier is allocated to the terminal for data transmission and reception. The terminal only needs to perform relevant operations within this part of the bandwidth configured by the network, thus achieving the effect of terminal energy saving. Based on the 5G NR Rel-15 standard, for each serving cell of the terminal, the network RRC can configure one or more BWPs for the terminal on this serving cell, and the maximum number of configurable BWPs is 4. At each moment, the terminal can only have 1 active DownLink (DL) BWP and 1 active UpLink (UL) BWP on this serving cell, and the terminal can only perform data transmission and reception on the active BWP.

[0057] The terminal obtains the downlink or uplink scheduling information by receiving the PDCCH sent by the network, and then further completes the reception and transmission of service data. The time when the network schedules the terminal is not fixed. Since there is no relevant signaling to inform the terminal whether the network has sent PDCCH to this terminal, the terminal needs to blindly detect the PDCCH. To reduce the complexity of the terminal's blind detection, it is necessary to limit the set of blindly detected PDCCHs. Therefore, the concept of search space is introduced, that is, the set of PDCCH resources that the terminal needs to blindly detect. The network can configure one or more PDCCH search spaces for each BWP of the terminal. The terminal only listens for the PDCCH on the PDCCH search space corresponding to the currently active BWP to complete data transmission and reception.

[0058] Furthermore, in the solution of this embodiment, the terminal device needs to be a terminal device configured with DRX function. The DRX in 5G NR is described as follows:

[0059] In 5G NR, the network can configure the DRX function for the terminal, enabling the terminal to listen to the PDCCH discontinuously to achieve the purpose of power saving for the terminal. Each Media Access Control (MAC) entity has a corresponding DRX configuration, and the DRX configuration parameters include at least one of the following:

[0060] -drx-onDurationTimer (DRX - On Duration Timer): The duration for which the UE wakes up at the start of a DRX Cycle;

[0061] -drx-SlotOffset (DRX Slot Offset): The delay for the UE to start the drx-onDurationTimer;

[0062] -drx-InactivityTimer (DRX - Inactivity Timer): The duration for which the UE continues to listen to the PDCCH after receiving a PDCCH indicating an uplink initial transmission or a downlink initial transmission;

[0063] -drx-RetransmissionTimerDL (DRX - Downlink DL Retransmission Timer): The maximum duration for which the UE listens to the PDCCH indicating a downlink retransmission schedule. Each downlink HARQ process other than the broadcast HARQ process corresponds to a drx-RetransmissionTimerDL;

[0064] -drx-RetransmissionTimerUL (DRX - Uplink Retransmission Timer): The maximum duration for which the UE listens to the PDCCH indicating an uplink retransmission schedule. Each uplink HARQ process corresponds to a drx-RetransmissionTimerUL;

[0065] -drx-LongCycleStartOffset (DRX - Long Cycle Start Offset): Used to configure the Long DRX cycle and the subframe offset at the start of the Long DRX cycle and the Short DRX Cycle;

[0066] -drx-ShortCycle (DRX - Short Cycle): The Short DRX cycle, which is an optional configuration;

[0067] -drx-ShortCycleTimer (DRX - Short Cycle Timer): The duration for which the UE is in the Short DRX cycle (and has not received any PDCCH), which is an optional configuration;

[0068] -drx-HARQ-RTT-TimerDL (DRX-HARQ-RTT Downlink Timer): The minimum waiting time that the UE expects to receive the PDCCH indicating downlink scheduling. Each downlink HARQ process, except for the broadcast HARQ process, corresponds to a drx-HARQ-RTT-TimerDL;

[0069] -drx-HARQ-RTT-TimerUL (DRX-HARQ-RTT Uplink Timer): The minimum waiting time that the UE expects to receive the PDCCH indicating uplink scheduling. Each uplink HARQ process corresponds to a drx-HARQ-RTT-TimerUL.

[0070] If the terminal is configured with DRX, the terminal needs to monitor the PDCCH during the DRX Active Time. The DRX Active Time includes at least one of the following cases:

[0071] - Any one of the five timers, namely drx-onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimerDL, drx-RetransmissionTimerUL, and ra-ContentionResolutionTimer, is running;

[0072] - An SR has been sent on the PUCCH and is in the pending state;

[0073] - During the contention-based random access procedure, the terminal has not received an initial transmission indicated by the PDCCH scrambled with C-RNTI after successfully receiving the random access response.

[0074] Regarding the relationship between the DRX cycle, the DRX On duration, and the terminal device's monitoring of the PDCCH, please refer to Figure 1-2 as shown. Among them, the terminal device monitors the PDCCH during the DRX-On Duration. Specifically, the terminal decides the time to start the drx-onDurationTimer according to whether it is in a short DRX cycle or a long DRX cycle. The specific regulations are as follows:

[0075] 1> If the Short DRX Cycle is used and the current subframe satisfies [(SFN × 10) + subframenumber] modulo (drx-ShortCycle) = (drx-StartOffset) modulo (drx-ShortCycle); or

[0076] 1> If the Long DRX Cycle is used and the current subframe satisfies [(SFN × 10) + subframenumber] modulo (drx-LongCycle) = drx-StartOffset;

[0077] 2> Start the drx-onDurationTimer at the moment after drx-SlotOffset slots starting from the current subframe.

[0078] Based on the Rel-15 NR standard, each MAC entity corresponds to a DRX configuration. During the standardization process of NR Rel-16, in the RAN2#108 meeting, an enhanced cDRX method in the NR CA scenario has been agreed, that is, a scheme where 2 DRX groups can be configured for one MAC entity. For this DRX enhancement method, the following clear conclusions have been formed:

[0079] The purpose of introducing the secondary DRX group is to configure different DRX groups for FR1 and FR2;

[0080] For the secondary DRX group, the network can configure a drx-InactivityTimer and a drx-onDurationTimer for it. That is, the network configures the drx-InactivityTimer and the drx-onDurationTimer for the 2 DRX groups respectively, and the remaining DRX configuration parameters are the common configuration parameters of the 2 DRX groups; and,

[0081] Cross-carrier scheduling between the 2 DRX groups is not supported.

[0082] Based on the above description, in order to more comprehensively understand the features and technical content of the embodiments of the present invention, the implementation of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The accompanying drawings are only for reference and explanation, and are not used to limit the embodiments of the present invention.

[0083] The embodiments of the present invention provide a monitoring control method, as Figure 2 shown, including:

[0084] Step 21: The terminal device receives indication information;

[0085] Among them, the indication information is used to determine to skip Physical Downlink Control Channel (PDCCH) monitoring during at least part of the duration of the Discontinuous Reception (DRX) activation time of at least some of the serving cells among all the serving cells.

[0086] Among them, all the serving cells include: the primary serving cell (PCell, Primary cell) of the terminal device, and N secondary serving cells (SCell, Secondary cell) in the active state, where N is an integer greater than or equal to 1.

[0087] Correspondingly, the network device side also provides a monitoring control method, as Figure 3 shown, including:

[0088] Step 31: The network device sends indication information.

[0089] Among them, the indication information is used to determine to skip PDCCH monitoring during at least part of the duration of the DRX activation time of at least some of the serving cells among all the serving cells.

[0090] Among them, all the serving cells include: the primary serving cell (PCell, Primary cell) of the terminal device, and N secondary serving cells SCell in the active state, where N is an integer greater than or equal to 1.

[0091] The embodiments of the present invention are applicable to the CA scenario, especially applicable to the CA scenario of 5G New Radio (NR). The description of CA has been provided above and will not be repeated here.

[0092] In this embodiment, after the terminal device receives the indication information, it may include:

[0093] The terminal device determines the serving cells for which to skip PDCCH monitoring and the time range for which to skip PDCCH monitoring according to the indication information.

[0094] That is to say, the terminal device can further determine whether to perform the process of skipping PDCCH monitoring in all the serving cells, or only in some of the serving cells among all the serving cells according to the indication information; in addition, while determining the range of the serving cells, it can also further determine within what time range to skip PDCCH monitoring according to the indication information.

[0095] The above-mentioned skipping of PDCCH monitoring can be specifically understood as: stopping monitoring of the PDCCH during the DRX activation time (or during the duration of DRX On); or, it can be understood as not monitoring the PDCCH during the DRX activation time.

[0096] Based on the above description and in combination with the following multiple examples, for different contents of the indication information or different serving cells for sending the indication information, it is respectively described how to determine the serving cell that skips PDCCH monitoring and how to determine the time range for skipping PDCCH monitoring:

[0097] Example 1:

[0098] For the specific processing procedure, refer to Figure 4 , including the following steps:

[0099] Step 41: The terminal device receives the configuration information sent by the network device; correspondingly, the network device sends the configuration information to the terminal device. Among them, the configuration information may be RRC configuration information.

[0100] Among them, the RRC configuration information may include parameters for configuring DRX, parameters related to SCell, and parameters related to PDCCH skipping, etc. Specifically, the RRC configuration information may include at least one of the following:

[0101] 1) DRX configuration parameters, which may include: long DRX cycle, drx-onDurationTimer, drx-InactivityTimer, etc.; the content and related functions included in the DRX configuration parameters have been described in detail in the foregoing embodiments and will not be elaborated here.

[0102] 2) The SCell configuration parameters at least include the SCell Index (index);

[0103] 3) For the PCell and each SCell, configure at least one DL BWP, and configure at least one PDCCH search space for at least one of the DL BWPs;

[0104] 4) The available duration that the terminal device supports for skipping PDCCH monitoring. That is to say, the network device can configure at least one supported PDCCH skipping duration value for the terminal device, that is, the duration that the PDCCH can indicate that the UE does not monitor the PDCCH.

[0105] It should be noted that in this step, the network device mentioned may be the network device of the serving cell to which the terminal device is currently connected. For example, it may be the network device corresponding to the primary serving cell of the terminal device.

[0106] In addition, the available duration for skipping PDCCH monitoring supported by the terminal device, in addition to being sent to the terminal device through the RRC configuration information as described above, can also be a preset value, for example, a value preset according to the protocol. For example, at least one PDCCH skipping duration value supported by the UE is given in a predefined manner.

[0107] The available duration for skipping PDCCH monitoring supported by the terminal device may specifically include: one or more available durations for skipping PDCCH monitoring supported by the terminal device. In addition, the duration of the available duration for skipping PDCCH monitoring may be greater than the duration when DRX is turned on (or the length of the DRX activation time), or may not be greater than the duration when DRX is turned on (or the length of the DRX activation time), and this embodiment does not limit it.

[0108] Based on the configuration of this step, later, according to whether the terminal device is within the DRX activation time, step 42 or step 44 can be executed respectively; specifically, when the terminal device is within the DRX activation time, step 42 is executed, and when the terminal device is within the DRX non - activation time, step 44 is executed.

[0109] Step 42: The terminal device receives first indication information sent by the network device corresponding to the first serving cell within the DRX activation time; wherein, the first indication information includes: the duration for skipping PDCCH monitoring is the first duration.

[0110] Among them, the first serving cell is one of the PCell of the terminal device and N SCell in the active state.

[0111] That is to say, the indication information in step 21 or step 31 can specifically be the first indication information in this example. In this step, the first indication information can be carried by the PDCCH.

[0112] Correspondingly, the network device corresponding to the first serving cell of the terminal device sends the first indication information to the terminal device within the DRX activation time of the terminal device.

[0113] This first serving cell can be understood as any one of all the serving cells of the terminal device.

[0114] Among them, the first indication information may include the specific time length of the first duration.

[0115] Alternatively, the first indication information may only include information related to a first duration. Specifically, since the available durations for skipping PDCCH monitoring supported by the (one or more) terminal devices have been configured in step 41; different available durations for skipping PDCCH monitoring may correspond to different related information. For example, the related information may be an index or different numbers, or different identifiers. Correspondingly, in this step, the first indication information may only include information related to one duration (such as an index), which can further reduce signaling overhead.

[0116] Step 43: The terminal device determines to skip PDCCH monitoring for all serving cells of the terminal device according to the first indication information, and determines that the start time of skipping PDCCH monitoring is the next time unit after receiving the first indication information, and the duration of skipping PDCCH monitoring is the first duration.

[0117] That is to say, in this example, when the terminal device receives the first indication information sent by any one of the serving cells, it determines that the serving cells for which PDCCH monitoring is skipped are all serving cells;

[0118] And it determines that the time range for skipping PDCCH monitoring is from the first time unit after receiving the first indication information, and the duration is the first duration.

[0119] Among them, the time unit may be a symbol, and of course it may also be other time units, such as a time slot, etc., which are not enumerated here.

[0120] Combining the above steps 42 - 43, taking the time unit as a symbol as an example: The terminal device receives the PDCCH skipping information (that is, carrying the first indication information) indicated by the PDCCH from any one of the serving cells during the DRX active time, which includes the first duration, such as the PDCCH skipping duration. This first duration is the duration during which the terminal device does not monitor the PDCCH;

[0121] Then the terminal device starts from the next symbol after completing the PDCCH reception and does not monitor the PDCCH on all serving cells during the subsequent PDCCH skipping duration.

[0122] Step 44: The terminal device receives second indication information sent by the network device corresponding to the primary serving cell (PCell) during the DRX inactive time; where the second indication information includes: the duration of skipping PDCCH monitoring is the second duration.

[0123] That is to say, the indication information in step 21 or step 31 can specifically be the second indication information in this example. In this step, the second indication information can be carried by a wake-up signal (WUS, WakeUp Signal).

[0124] Correspondingly, in this step, the network device can be the network device corresponding to the primary serving cell (PCell) of the terminal device. The network device sends the second indication information to the terminal device during the DRX inactivity time of the terminal device.

[0125] Among them, the second indication information can include the specific time length of the second duration.

[0126] Alternatively, the second indication information can only include information related to a second duration. Specifically, since the available duration for skipping PDCCH monitoring supported by the (one or more) terminal devices has been configured in step 41; different available durations for skipping PDCCH monitoring can correspond to different related information. For example, the related information can be an index (Index) or different numbers, or different identifiers. Correspondingly, in this step, the second indication information can only include information related to a second duration (such as an index), which can further reduce signaling overhead.

[0127] Step 45: The terminal device determines the serving cell for skipping PDCCH monitoring and the time range for skipping PDCCH monitoring according to the second indication information.

[0128] Specifically, for the serving cell for skipping PDCCH monitoring, all serving cells of the terminal device skip PDCCH monitoring.

[0129] That is, in this example, whether it is the first indication information or the second indication information, it is for all serving cells of the terminal device.

[0130] The time range for skipping PDCCH monitoring is one of the following:

[0131] The start time for skipping PDCCH monitoring is the next time unit after receiving the second indication information, and the duration for skipping PDCCH monitoring is the second duration;

[0132] Or,

[0133] The start time for skipping PDCCH monitoring is at the moment when the next DRX continuous timer starts, and the duration for skipping PDCCH monitoring is the second duration.

[0134] Combining the above steps 44 and 45, an example is given for illustration:

[0135] When the terminal device is in the DRX inactive time and receives the WUS indication PDCCH skipping information (the second indication information) from the PCell, which includes the second PDCCH skipping duration, that is, the second duration during which the UE does not monitor the PDCCH;

[0136] Then the terminal device does not monitor the PDCCH on all serving cells during the subsequent PDCCH skipping duration. Among them, for the determination of the starting moment when the terminal device does not monitor the PDCCH, there are the following two methods:

[0137] Method 1: The starting time for skipping PDCCH monitoring is the next time unit after receiving the second indication information, and the duration for skipping PDCCH monitoring is the second duration. That is to say, the terminal device starts not to monitor the PDCCH from the next symbol after completing the reception of the scheduled WUS, as Figure 5 shown.

[0138] Method 2: The starting time for skipping PDCCH monitoring is the moment when the next DRX continuous timer starts, and the duration for skipping PDCCH monitoring is the second duration. That is to say, the terminal device starts not to monitor the PDCCH from the moment when the subsequent drx-onDuraionTimer starts, as Figure 6 shown.

[0139] In an example, in the CA scenario, for a UE configured with DRX, the network can indicate the terminal device to skip PDCCH monitoring (PDCCH skipping) on all serving cells by sending a PDCCH on any one of the serving cells of the terminal device or sending a WUS indication on the PCell. The time range for the UE to skip PDCCH monitoring on all serving cells (which can be called the PDCCH skipping on duration) is the same.

[0140] Combined with Figure 7, an exemplary description of the solution of this example is given. Assume that the terminal device has one PCell and three SCell, denoted as Scell1, 2, and 3 respectively; within a DRX cycle, during the DRX active time, the terminal device receives an indication A (i.e., a first indication message) carried by PDCCH sent by the network device of Scell2, where the first duration - A is indicated. Then the terminal device determines to skip PDCCH for all serving cells and determines the time range for skipping PDCCH listening as follows: starting from the next symbol of this indication A, with a duration of the first duration - A.

[0141] Within another DRX cycle, during the DRX active time, the terminal device receives an indication B (i.e., another first indication message) carried by PDCCH sent by the network device of Scell1, where the first duration - B is indicated. Then the terminal device determines to skip PDCCH for all serving cells and determines the time range for skipping PDCCH listening as follows: starting from the next symbol of this indication B, with a duration of the first duration - B.

[0142] During the DRX inactive time, the terminal device receives an indication C carried by WUS sent by the network device of the primary serving cell PCell, where the second duration is indicated. Then the terminal device determines to skip PDCCH for all serving cells and determines the time range for skipping PDCCH listening as follows: at the moment when the next DRX continuous timer starts after this indication C, with a duration of the second duration.

[0143] Example 2

[0144] The specific implementation process is as Figure 8 shown, including the following steps:

[0145] Step 51: The terminal device receives the configuration information sent by the network device; correspondingly, the network device sends configuration information to the terminal device. Among them, the configuration information can be RRC configuration information.

[0146] Among them, the RRC configuration information may include parameters for configuring DRX, parameters related to SCell, and parameters related to PDCCH skipping, etc. Specifically, the RRC configuration information may include at least one of the following:

[0147] 1) DRX configuration parameters may include: configuring multiple DRX groups for a MAC entity of a terminal device (in one example, 2 DRX groups may be configured), and related configuration parameters corresponding to all DRX groups. Different DRX groups may correspond to different related configuration parameters. For example, 2 DRX groups may respectively correspond to different drx-InactivityTimer and / or drx-onDurationTimer configurations, etc.

[0148] 2) The SCell configuration parameters at least include the SCell Index.

[0149] 3) For the PCell and each SCell, configure at least one DL BWP, and configure at least one PDCCH search space for at least one of the DL BWPs.

[0150] 4) The available duration of skipping PDCCH monitoring supported by the terminal device. That is to say, the network device can configure at least one supported PDCCH skipping duration value for the terminal device, that is, the duration during which the PDCCH can indicate that the UE does not monitor the PDCCH.

[0151] 5) The corresponding relationship between different DRX groups and serving cells among all the DRX groups. Specifically, it may include the corresponding relationship between each SCell and the DRX group. Different SCells are respectively corresponding to one of the 2 configured DRX groups. In addition, the PCell is defaultly corresponding to DRX group 1.

[0152] It should be noted that the network device described in this step may be the network device of the serving cell to which the terminal device is currently connected. For example, it may be the network device corresponding to the primary serving cell of the terminal device. Of course, it may also be configured for the terminal device by the secondary serving cell in the active state. There is no limitation here.

[0153] In addition, the available duration of skipping PDCCH monitoring supported by the terminal device, in addition to being sent to the terminal device through the RRC configuration information as described above, may also be a preset value. For example, it may be a value preset according to the protocol. For example, at least one PDCCH skipping duration value supported by the terminal device is given in a predefined manner.

[0154] The available duration for skipping PDCCH monitoring supported by the terminal device may specifically include: one or more available durations for skipping PDCCH monitoring supported by the terminal device. Additionally, the duration of the available duration for skipping PDCCH monitoring may be greater than the duration of DRX activation (or the length of the DRX activation time), or alternatively, may not be greater than the duration of DRX activation (or the length of the DRX activation time). This embodiment does not limit it.

[0155] Based on the configuration of this step, later, according to whether the terminal device is within the DRX activation time, step 52 or step 54 can be respectively executed; specifically, when the terminal device is within the DRX activation time, step 52 is executed, and when the terminal device is within the DRX non - activation time, step 54 is executed.

[0156] Step 52: The terminal device receives third indication information sent by the network device corresponding to the second serving cell during the activation time of the first DRX group; wherein, the third indication information includes: the duration for skipping PDCCH monitoring is the third duration;

[0157] Among them, the second serving cell is one of the serving cells included in the first DRX group; the first DRX group is one of the multiple DRX groups of the terminal device.

[0158] This step can be understood as that the terminal device can receive the third indication information sent by the network device of any one serving cell (corresponding to the DRX group) during the activation time of any one of the multiple DRX groups. Just for the convenience of understanding, any one of the DRX groups is later referred to as the first DRX group, and any one of the serving cells in this DRX group is referred to as the second serving cell. The second serving cell can also be any one of the PCell or Scell.

[0159] That is to say, the indication information in step 21 or step 31 can specifically be the third indication information in this example. In this step, the third indication information can be carried by the PDCCH.

[0160] Correspondingly, the network device corresponding to the second serving cell of the terminal device sends the third indication information to the terminal device during the DRX activation time of the first DRX group of the terminal device.

[0161] Among them, the third indication information may include the specific time length of the first duration.

[0162] Alternatively, the third indication information may only include the relevant information of a third duration. Specifically, since the available durations for skipping PDCCH monitoring supported by the (one or more) terminal devices have been configured in step 51; different available durations for skipping PDCCH monitoring may correspond to different relevant information. For example, the relevant information may be an index or different numbers, or different identifiers. Correspondingly, in this step, the third indication information may only include the relevant information (such as an index) of one duration, which can further reduce signaling overhead.

[0163] Step 53: The terminal device determines to skip PDCCH monitoring for all serving cells included in the first DRX group according to the third indication information, and determines that the start time of skipping PDCCH monitoring is the next time unit after receiving the third indication information, and the duration of skipping PDCCH monitoring is the third duration.

[0164] That is to say, in this example, when the terminal device receives the third indication information sent by any one of the serving cells in any one DRX group, it determines that the serving cells for which PDCCH monitoring is skipped are all the serving cells included in this DRX group;

[0165] And it determines that the time range for skipping PDCCH monitoring is from the first time unit after receiving the first indication information, and the duration is the first duration.

[0166] Among them, the time unit may be a symbol, and of course it may also be other time units, such as a time slot, etc. Here, it is not exhaustively listed.

[0167] Combining the above steps 52 - step 53, taking the time unit as a symbol as an example for illustration:

[0168] For each DRX group, at the active time of the DRX group, the terminal device receives the PDCCH skipping information (the third indication information) carried by the PDCCH indication from any one of the serving cells corresponding to the DRX group, which includes the PDCCH skipping duration (the third duration), that is, the third duration during which the UE does not monitor the PDCCH;

[0169] Then the terminal device starts from the next symbol after completing the PDCCH reception (that is, after completing the reception of the third indication information), and does not monitor the PDCCH on all serving cells corresponding to the DRX group during the subsequent PDCCH skipping duration time (the third duration).

[0170] Step 54: The terminal device receives fourth indication information sent by the network device corresponding to the primary serving cell (PCell) during the inactive time of the second DRX group; wherein, the fourth indication information includes: the duration for skipping PDCCH monitoring is the fourth duration.

[0171] That is, the terminal device receives the WUS indication PDCCH skipping information (the fourth indication information) from the PCell during the DRX inactive time (for example, the inactive time of the second DRX group), which includes the PDCCH skipping duration (the fourth duration), that is, the duration during which the UE does not monitor the PDCCH.

[0172] The indication information in Step 21 or Step 31 can specifically be the fourth indication information in this example. In this step, the fourth indication information can be carried by a Wake-Up Signal (WUS).

[0173] Correspondingly, in this step, the network device can be the network device corresponding to the primary serving cell (PCell) of the terminal device, and the network device sends the fourth indication information to the terminal device during the DRX inactive time of the terminal device.

[0174] In this step, the second DRX group can be the DRX group where the PCell is located. Correspondingly, the network device in this step can be the network device corresponding to the primary serving cell (PCell), that is, the network device corresponding to the primary serving cell (PCell) sends the fourth indication information to the terminal device during the inactive time of the second DRX group of the terminal device.

[0175] Among them, the fourth indication information can include the specific time length of the fourth duration.

[0176] Alternatively, the fourth indication information can only include relevant information about a fourth duration. Specifically, since the available durations for skipping PDCCH monitoring supported by the terminal device have been configured in Step 51; different available durations for skipping PDCCH monitoring can correspond to different relevant information. For example, the relevant information can be an index or different numbers or different identifiers. Correspondingly, in this step, the fourth indication information can only include relevant information about a fourth duration (such as an index), which can further reduce signaling overhead.

[0177] Step 55: The terminal device determines the serving cell for skipping PDCCH monitoring and the time range for skipping PDCCH monitoring according to the fourth indication information.

[0178] Specifically, the terminal device determining the serving cell to skip PDCCH monitoring according to the fourth indication information may include one of the following situations:

[0179] Situation 1: The terminal device determines, according to the fourth indication information, that the serving cell to skip PDCCH monitoring is all serving cells. That is, the terminal device does not monitor PDCCH on all serving cells during the subsequent PDCCH skipping duration (the fourth duration).

[0180] Or,

[0181] Situation 2: The terminal device determines, according to the fourth indication information, that the serving cells to skip PDCCH monitoring are all serving cells within the second DRX group corresponding to the primary serving cell. That is, the terminal device does not monitor PDCCH on all serving cells corresponding to DRX group 1 (i.e., the second DRX group corresponding to the PCell) during the subsequent PDCCH skipping duration (the fourth duration).

[0182] Or,

[0183] Situation 3:

[0184] In the fourth indication information, it further includes: the target DRX group that skips PDCCH monitoring among all DRX groups.

[0185] Correspondingly, determining the serving cell to skip PDCCH monitoring according to the indication information includes:

[0186] The terminal device determines, according to the fourth indication information, to skip PDCCH monitoring on all serving cells within the target DRX group.

[0187] In this situation, in the fourth indication information, it can be in the form of a bitmap. For example, there are two DRX groups, and each bit corresponds to a DRX group. When the bit is set to the first value, the corresponding DRX group indicates skipping PDCCH monitoring, and when the bit is set to the second value, the corresponding DRX group indicates not skipping PDCCH monitoring. Among them, the first value can be 1, the second value can be 0, or vice versa.

[0188] For example, for two DRX groups, DRX group 1 and 2, the bitmap contains two bits. The first bit corresponds to DRX group 1, and the second bit corresponds to DRX group 2. If the fourth indication information indicates 01, it means that DRX group 2 is the target DRX group, and all serving cells within this DRX group (or corresponding to this DRX group) skip PDCCH monitoring.

[0189] That is, the network device uses the bitmap method through the WUS (the carried fourth indication information) to indicate whether to skip the PDCCH for the serving cells of each DRX group respectively. Then, the terminal device does not monitor the PDCCH on all the serving cells corresponding to the DRX group that needs to skip the PDCCH within the subsequent PDCCH skipping duration based on the indication of the WUS.

[0190] Determine the time range for skipping PDCCH monitoring, including one of the following:

[0191] The start time of skipping PDCCH monitoring is the next time unit after receiving the fourth indication information, and the duration of skipping PDCCH monitoring is the fourth duration;

[0192] Or,

[0193] The start time of skipping PDCCH monitoring is at the moment when the next DRX continuous timer starts, and the duration of skipping PDCCH monitoring is the fourth duration.

[0194] The specific processing method of the time range for skipping PDCCH monitoring is similar to that in Example 1, and will not be elaborated here.

[0195] In one example, in the CA scenario, for a terminal device configured with multiple DRX groups, for each DRX group, the network can indicate the PDCCH skipping for all the serving cells corresponding to the DRX group on any one of the serving cells corresponding to the DRX group by sending a PDCCH, and the PDCCH skipping on duration for all the serving cells corresponding to the DRX group is the same for the terminal device.

[0196] Combined with Figure 9 , an exemplary description of the solution of this example is given. Assume that the terminal device has two DRX groups, namely DRX group 1 and 2. DRX group 1 includes a PCell and an SCell 1, and DRX group 2 includes SCell2 and 3; within one DRX cycle, during the DRX active time, the terminal device receives the third indication information - A carried by the PDCCH sent by the network device of the primary serving cell PCell of DRX group 1, where the third duration - A is indicated. Then, the terminal device determines that all the serving cells in DRX group 1 perform PDCCH skipping, and determines the time range for skipping PDCCH monitoring as: starting from the next Symbol of this third indication information A, with a duration of the third duration - A.

[0197] In another DRX cycle, within the DRX active time, the terminal device receives the third indication information B carried by the PDCCH sent by the network device of Scell1, where the third duration - B is indicated. Then the terminal device determines to skip the PDCCH for all serving cells of DRX group 1, and determines the time range for skipping PDCCH monitoring as: starting from the next symbol of the third indication information B, with a duration of the third duration - B. Additionally, the terminal device receives the third indication information - C sent by the network device of SCell 3 in DRX group 2. Then the terminal device determines to skip the PDCCH for all serving cells of DRX group 2, and determines the time range for skipping PDCCH monitoring as: starting from the next symbol of the third indication information C, with a duration of the third duration - C.

[0198] Within the DRX inactive time, the terminal device receives the fourth indication information carried by the WUS sent by the network device of the primary serving cell PCell, where the fourth duration is indicated. Then the terminal device determines to skip the PDCCH for all serving cells, and determines the time range for skipping PDCCH monitoring as: at the moment when the next DRX continuous timer starts after the fourth indication information, with a duration of the fourth duration.

[0199] Example 3

[0200] The specific implementation process is as Figure 10 shown, and includes the following steps:

[0201] Step 61: The terminal device receives the configuration information sent by the network device; correspondingly, the network device sends the configuration information to the terminal device. Among them, the configuration information can be RRC configuration information.

[0202] Among them, the RRC configuration information may include parameters for configuring DRX - related parameters, SCell - related parameters, and PDCCH skipping - related parameters, etc. Specifically, the RRC configuration information may include at least one of the following:

[0203] 1) DRX configuration parameters, which may include: configuring multiple DRX groups for a MAC entity of the terminal device (in one example, 2 DRX groups can be configured), and the relevant configuration parameters corresponding to all DRX groups. Different DRX groups may correspond to different relevant configuration parameters. For example, the 2 DRX groups can respectively correspond to different drx - InactivityTimer and / or drx - onDurationTimer configurations, etc.

[0204] 2) The SCell configuration parameters at least include the SCell Index.

[0205] 3) For each PCell and each SCell, configure at least one DL BWP, and configure at least one PDCCH search space for at least one of the DL BWPs;

[0206] 4) The available duration for skipping PDCCH monitoring supported by the terminal device. That is, the network device can configure at least one supported PDCCH skipping duration value for the terminal device, that is, the duration during which the UE indicated by the PDCCH does not monitor the PDCCH;

[0207] 5) The corresponding relationship between different DRX groups and serving cells in all the DRX groups. Specifically, it may include the corresponding relationship between each SCell and a DRX group, and different SCells are respectively mapped to one of the two configured DRX groups. In addition, the PCell is defaultly mapped to DRX group 1. Among them, different DRX groups include different serving cells.

[0208] 6) Cell grouping information for PDCCH skipping indication: For each DRX group, group the serving cells corresponding to the DRX group, and establish a mapping relationship between the serving cells and cell groups, that is, the corresponding relationship between each serving cell in each DRX group and a cell group. Among them, each serving cell is mapped to one of the cell groups, and different cell groups include different serving cells.

[0209] It should be noted that the network device mentioned in this step can be the network device of the serving cell to which the terminal device is currently connected. For example, it can be the network device corresponding to the primary serving cell of the terminal device. Of course, it can also be configured by the activated secondary serving cell for the terminal device, which is not limited here.

[0210] In addition, the available duration for skipping PDCCH monitoring supported by the terminal device, in addition to being sent to the terminal device through the RRC configuration information as described above, can also be a preset value. For example, it can be a value preset according to the protocol. For example, at least one PDCCH skipping duration value supported by the terminal device is given in a predefined manner

[0211] The available duration for skipping PDCCH monitoring supported by the terminal device may specifically include: one or more available durations for skipping PDCCH monitoring supported by the terminal device. Additionally, the duration of the available duration for skipping PDCCH monitoring may be greater than the duration of DRX activation (or the length of the DRX activation time), or alternatively, may not be greater than the duration of DRX activation (or the length of the DRX activation time), and this embodiment does not limit it.

[0212] Based on the configuration of this step, subsequently, according to whether the terminal device is within the DRX activation time, step 62 or step 64 can be respectively executed; specifically, when the terminal device is within the DRX activation time, step 62 is executed, and when the terminal device is within the DRX non - activation time, step 64 is executed.

[0213] Step 62: The terminal device receives the fifth indication information sent by the network device corresponding to the third serving cell within the DRX activation time of the first cell group; wherein, the fifth indication information includes: the duration for skipping PDCCH monitoring is the fifth duration;

[0214] Wherein, the third serving cell is one of the serving cells included in the first cell group.

[0215] This step can be understood as that the terminal device can receive the fifth indication information sent by (the network device of) any one serving cell corresponding to a cell group within the activation time of any one cell group among multiple cell groups. Just for the convenience of understanding, any one of the DRX groups is hereinafter referred to as the first cell group, and any one serving cell in this cell group is referred to as the third serving cell. The third serving cell can also be any one of the PCell or the Scell.

[0216] That is to say, the indication information in step 21 or step 31 can specifically be the fifth indication information in this example. In this step, the fifth indication information can be carried by the PDCCH.

[0217] Correspondingly, the network device corresponding to the third serving cell of the terminal device sends the fifth indication information for the terminal device within the DRX activation time of the first cell group of the terminal device.

[0218] Wherein, the fifth indication information can include the specific time length of the fifth duration.

[0219] Alternatively, the fifth indication information may only include the relevant information of a fifth duration. Specifically, since the available durations for skipping PDCCH monitoring supported by the (one or more) terminal devices have been configured in step 61; different available durations for skipping PDCCH monitoring may correspond to different relevant information. For example, the relevant information may be an index or different numbers, or different identifiers. Correspondingly, in this step, the fifth indication information may only include the relevant information of one duration (such as an index), which can further reduce signaling overhead.

[0220] Step 63: The terminal device determines to skip PDCCH monitoring for all serving cells included in the first cell group according to the fifth indication information, and determines that the start time of skipping PDCCH monitoring is the next time unit after receiving the fifth indication information, and the duration of skipping PDCCH monitoring is the fifth duration.

[0221] That is to say, in this example, when the terminal device receives the fifth indication information sent by any one of the serving cells in any one of the cell groups, it determines that the serving cells for which PDCCH monitoring is skipped are all the serving cells included in this cell group;

[0222] And it determines that the time range for skipping PDCCH monitoring is from the first time unit after receiving the fifth indication information, and the duration is the fifth duration.

[0223] Among them, the time unit may be a symbol, and of course it may also be other time units, such as a slot, etc., which will not be enumerated here.

[0224] Combining the above steps 62 - step 63, taking the time unit as a symbol as an example for illustration:

[0225] For each cell group, when the terminal device receives the PDCCH indication PDCCH skipping information (the fifth indication information), including the PDCCH skipping duration, that is, the duration (the fifth duration) during which the UE does not monitor the PDCCH, from any one of the serving cells corresponding to this cell group in the active time of the DRX group corresponding to each cell group, the UE starts not to monitor the PDCCH on all the serving cells corresponding to this cell group in the subsequent PDCCH skipping duration time (the fifth duration) starting from the next symbol after completing the PDCCH reception.

[0226] Step 64: The terminal device receives sixth indication information sent by a network device corresponding to a primary serving cell (PCell) during a DRX inactivity time; wherein, the sixth indication information includes: the duration for skipping PDCCH monitoring is a sixth duration.

[0227] In this step, the DRX inactivity time can be the inactivity time of all cell groups, or can be the inactivity time of the cell group where the primary serving cell is located.

[0228] That is, the UE receives WUS indication PDCCH skipping information from the PCell during the DRX inactive time, which includes the PDCCH skipping duration, that is, the duration for which the UE does not monitor the PDCCH.

[0229] The indication information in Step 21 or Step 31 can specifically be the sixth indication information in this example. In this step, the sixth indication information can be carried by a wake-up signal (WUS, WakeUp Signal).

[0230] Correspondingly, in this step, the network device can be a network device corresponding to the primary serving cell (PCell) of the terminal device, and the network device sends sixth indication information to the terminal device during the DRX inactivity time of the terminal device.

[0231] Among them, the sixth indication information can include the specific time length of the fourth duration.

[0232] Alternatively, the sixth indication information can only include relevant information about a fourth duration. The specific description is the same as the previous example and will not be elaborated here.

[0233] Step 65: The terminal device determines the serving cells for skipping PDCCH monitoring and the time range for skipping PDCCH monitoring according to the sixth indication information.

[0234] Specifically, the terminal device determining the serving cells for skipping PDCCH monitoring according to the fourth indication information can include one of the following situations:

[0235] Situation 1: The terminal device determines, according to the sixth indication information, that the serving cells for skipping PDCCH monitoring are all serving cells. That is, the UE does not monitor the PDCCH on all serving cells during the subsequent PDCCH skipping duration.

[0236] Or,

[0237] Scenario 2: The terminal device determines that the serving cells for skipping PDCCH monitoring are all the serving cells within the second cell group corresponding to the primary serving cell according to the sixth indication information. That is, the UE does not monitor PDCCH on all the serving cells corresponding to the cell group where the PCell is located during the subsequent PDCCH skipping duration.

[0238] It should be noted here that the second cell group may be the same as or different from the aforementioned first cell group. That is, if the first cell group is the group including the primary serving cell, then the first cell group is the same as the second cell group; otherwise, they are different.

[0239] Or,

[0240] Scenario 3:

[0241] In the sixth indication information, it further includes: the target cell group for skipping PDCCH monitoring among all the cell groups.

[0242] Correspondingly,

[0243] The terminal device determines the serving cells for skipping PDCCH monitoring according to the indication information, including:

[0244] The terminal device determines to skip PDCCH monitoring for all the serving cells within the target cell group according to the sixth indication information.

[0245] In this case, in the sixth indication information, it can be in the form of a bitmap. For example, there are 3 cell groups, and each bit corresponds to a cell group. When the bit is set to the first value, the corresponding cell group is the target cell group that skips PDCCH monitoring; when the bit is set to the second value, the corresponding cell group indicates not to skip PDCCH monitoring. Among them, the first value can be 1 and the second value can be 0, or vice versa.

[0246] That is, WUS uses the bitmap method to indicate whether the UE should skip PDCCH for each cell group respectively. The UE does not monitor PDCCH on all the serving cells corresponding to the cell groups that need to skip PDCCH during the subsequent PDCCH skipping duration based on the WUS indication.

[0247] Determining the time range for skipping PDCCH monitoring includes one of the following:

[0248] The start time for skipping PDCCH monitoring is the next time unit after receiving the fourth indication information, and the duration for skipping PDCCH monitoring is the fourth duration;

[0249] Alternatively,

[0250] The start time for skipping PDCCH monitoring is at the moment when the next DRX continuous timer starts, and the duration for skipping PDCCH monitoring is the fourth duration.

[0251] The specific processing method for the time range of skipping PDCCH monitoring is similar to that in Example 1 and will not be elaborated here.

[0252] In one example, in a CA scenario, for a UE configured with one or more DRX groups, the serving cells corresponding to each DRX group are grouped. For each cell group, the network can indicate to the UE to perform PDCCH skipping on all serving cells corresponding to the cell group by sending a PDCCH on any one of the serving cells corresponding to the cell group, and the PDCCH skipping onduration of the UE on all these serving cells is the same.

[0253] Combined with Figure 11 , an exemplary description of the solution in this example is given. Assume that the terminal device has two cell groups, namely cell group 1 and cell group 2. Cell group 1 contains a PCell and an SCell 1, and cell group 2 contains SCell2 and 3. Within one DRX cycle, during the DRX active time, the terminal device receives the fifth indication information -1 carried by the PDCCH sent by the network device of SCell1 in cell group 1, which indicates the fifth duration -1. Then the terminal device determines to perform PDCCH skipping on all serving cells corresponding to cell group 1, and determines the time range for skipping PDCCH monitoring as: starting from the next Symbol of this fifth indication information -1, with a duration of the fifth duration -1. During the DRX active time of the other cell group 2, the terminal device receives the fifth indication information -2 sent by the network device of SCell 3 in cell group 2. Then the terminal device determines to perform PDCCH skipping on all serving cells corresponding to cell group 2, and determines the time range for skipping PDCCH monitoring as: starting from the next Symbol of this fifth indication information -2, with a duration of the fifth duration -2.

[0254] During the DRX inactive time, the terminal device receives the sixth indication information carried by the WUS sent by the network device of the primary serving cell PCell, which indicates the sixth duration. Then the terminal device determines to perform PDCCH skipping on all serving cells corresponding to the cell group where the primary serving cell is located, and determines the time range for skipping PDCCH monitoring as: at the moment when the next DRX continuous timer starts after this sixth indication information, with a duration of the sixth duration.

[0255] Example 4

[0256] The specific implementation process is as follows Figure 12 shown, including the following steps:

[0257] Step 71, the terminal device receives the configuration information sent by the network device; correspondingly, the network device sends configuration information to the terminal device. Among them, the configuration information can be RRC configuration information.

[0258] Among them, the RRC configuration information may include parameters for configuring DRX-related parameters, SCell-related parameters, and PDCCH skipping-related parameters, etc. Specifically, the RRC configuration information may include at least one of the following:

[0259] 1) DRX configuration parameters, which may include: configuring multiple DRX groups for a MAC entity of the terminal device (in one example, 2 DRX groups can be configured), and the relevant configuration parameters corresponding to all DRX groups. Different DRX groups may correspond to different relevant configuration parameters. For example, 2 DRX groups may respectively correspond to different drx-InactivityTimer and / or drx-onDurationTimer configurations, etc.

[0260] 2) The SCell configuration parameters at least include the SCell Index (index);

[0261] 3) For the PCell and each SCell, configure at least one DL BWP, and configure at least one PDCCH search space for at least one of the DL BWPs;

[0262] 4) The available duration of skipping PDCCH monitoring supported by the terminal device. That is to say, the network device can configure at least one supported PDCCH skipping duration value for the terminal device, that is, the duration during which the PDCCH can indicate that the UE does not monitor the PDCCH;

[0263] 5) The corresponding relationship between different DRX groups and serving cells in all DRX groups. Specifically, it may include the corresponding relationship between each SCell and the DRX group, and different SCells are respectively corresponding to one of the 2 configured DRX groups. In addition, the PCell is defaultly corresponding to DRX group 1.

[0264] 6) Cell grouping information for PDCCH skipping indication: For each DRX group, group the serving cells corresponding to the DRX group, and establish a mapping relationship between the serving cells and the cell groups, that is, the corresponding relationship between each serving cell in each DRX group and the cell group. Among them, each serving cell corresponds to one of the cell groups, and different cell groups contain different serving cells.

[0265] The specific configuration content in this step is the same as that in the foregoing Example 3 and will not be elaborated here.

[0266] Based on the configuration of this step, later, according to whether the terminal device is within the DRX active time, step 72 or step 74 can be executed respectively; specifically, when the terminal device is within the DRX active time, execute step 72, and when the terminal device is within the DRX inactive time, execute step 74.

[0267] Step 72: The terminal device receives the seventh indication information sent by the network device corresponding to the fourth serving cell during the DRX active time; among them, the seventh indication information includes: the duration of skipping PDCCH monitoring is the seventh duration;

[0268] Among them, the fourth serving cell is one of all the serving cells of the terminal device.

[0269] In this step, the DRX active time can be understood as that all DRX groups of the terminal device adopt the same DRX cycle, that is, all DRX groups enter the DRX on state or the DRX active time at the same time, and the duration of DRX-On is also the same.

[0270] Of course, the DRX active time can also be the DRX active time corresponding to the cell group where the fourth serving cell is located, or the DRX active time corresponding to the DRX group where the fourth serving cell is located.

[0271] This step can be understood as that the terminal device can receive the seventh indication information sent by the network device of any one of the serving cells during the active time. Just for the convenience of understanding, any one of the serving cells is later referred to as the fourth serving cell. The fourth serving cell can be any one of the PCell or Scell.

[0272] That is to say, the indication information in step 21 or step 31 can specifically be the seventh indication information in this example. In this step, the seventh indication information can be carried by the PDCCH.

[0273] Correspondingly, the network device corresponding to the fourth serving cell of the terminal device sends seventh indication information to the terminal device within the DRX activation time of the terminal device.

[0274] Among them, the seventh indication information may include the specific time length of the fifth duration.

[0275] Alternatively, the seventh indication information may only include information related to a fifth duration. The specific description is similar to the foregoing example and will not be elaborated here.

[0276] In addition, different from the foregoing example, the seventh indication information further includes:

[0277] Whether each serving cell group in all serving cell groups skips PDCCH monitoring;

[0278] Or,

[0279] Whether each cell group corresponding to the DRX group where the fourth serving cell is located skips PDCCH monitoring.

[0280] Specifically, in addition to the foregoing seventh duration, the seventh indication information may further include a bitmap (bit map), and whether the serving cell group or the serving cell skips PDCCH monitoring is indicated through this bitmap.

[0281] Further, in one case, it is indicated through the bitmap whether each serving cell group in all serving cell groups skips PDCCH monitoring. That is, the PDCCH indicates whether each cell group in all cell groups of the UE needs to skip PDCCH.

[0282] For example, if the terminal device corresponds to 3 cell groups, namely cell groups 1, 2, and 3, the first value in the bitmap indicates skipping PDCCH monitoring, the second value indicates not skipping PDCCH monitoring, the first value is 1, the second value is 0, or vice versa; different bit positions in the bitmap correspond to different cell groups; if the bitmap is 101, it may indicate that cell group 1 skips PDCCH monitoring, all serving cells of cell group 2 do not skip PDCCH monitoring, and all serving cells of cell group 3 skip PDCCH monitoring.

[0283] Further, the seventh indication information may indicate the same seventh duration, that is, for the serving cells in one or more cell groups that need to skip PDCCH monitoring, the same seventh duration is used to skip PDCCH monitoring;

[0284] Or,

[0285] The seventh indication information may include multiple seventh time durations, where different seventh time durations are used to correspond to different cell groups that skip PDCCH monitoring. For example, if there are two cell groups that skip PDCCH monitoring, then two seventh time durations may be indicated, with different cell groups corresponding to different seventh time durations. The specific corresponding manner may be one-to-one correspondence in sequence.

[0286] In another case, whether each cell group corresponding to the DRX group where the fourth serving cell is located skips PDCCH monitoring. That is, the seventh indication information carried in the PDCCH is used to indicate whether each cell group in the cell group corresponding to the DRX group where the serving cell is located needs to skip PDCCH.

[0287] For example, the terminal device has 2 DRX groups, and the fourth serving cell is the serving cell in DRX group 2. Then the seventh indication information is used to indicate whether each serving cell in one or more serving cells in DRX group 2 skips PDCCH monitoring.

[0288] If DRX group 2 corresponds to 4 cell groups, namely cell groups 1, 2, 3, and 4, and the first value in the bitmap indicates skipping PDCCH monitoring and the second value indicates not skipping PDCCH monitoring, the first value is 1 and the second value is 0, or vice versa; different bit positions in the bitmap correspond to different cell groups; if the bitmap is 1010, then it can indicate that cell groups 1 and 3 in DRX group 2 skip PDCCH monitoring, and all serving cells in cell groups 2 and 4 in DRX group 2 do not skip PDCCH monitoring.

[0289] Further, the seventh indication information may indicate the same seventh time duration, that is, for the serving cells in one or more cell groups that need to skip PDCCH monitoring, the same seventh time duration is used to skip PDCCH monitoring;

[0290] Or,

[0291] The seventh indication information may include multiple seventh time durations, where different seventh time durations are used to correspond to different cell groups that skip PDCCH monitoring. For example, if there are two cell groups that skip PDCCH monitoring, then two seventh time durations may be indicated, with different cell groups corresponding to different seventh time durations. The specific corresponding manner may be one-to-one correspondence in sequence.

[0292] Step 73, the terminal device determines the serving cells that skip PDCCH monitoring and the time range for skipping PDCCH monitoring according to the seventh indication information.

[0293] In this example, the time range for determining to skip PDCCH monitoring is from the first time unit after receiving the fifth indication message, with a duration of the seventh duration.

[0294] Among them, the time unit can be a symbol, and of course it can also be other time units, such as a time slot, etc. Here, it is not enumerated exhaustively.

[0295] Combining the above steps 72 - step 73, taking the time unit as a symbol as an example for illustration:

[0296] The terminal device receives the seventh indication message, that is, the PDCCH skipping information, from any one of the serving cells during the active time. Specifically, it includes:

[0297] Using the bitmap method to respectively indicate whether each cell needs to skip the PDCCH. Specifically, it can be one of the following:

[0298] The PDCCH indicates whether each cell group in the cell group corresponding to the DRX group where the serving cell is located needs to skip the PDCCH;

[0299] The PDCCH indicates whether each cell group in all cell groups of the UE needs to skip the PDCCH.

[0300] Then, the duration for which the terminal device does not monitor the PDCCH (or skips PDCCH monitoring) starts from the next symbol after the terminal device completes the PDCCH reception, and within the subsequent PDCCH skipping duration (the seventh duration), it does not monitor the PDCCH on the serving cells corresponding to all cell groups that need to skip the PDCCH.

[0301] It should be understood that if the seventh duration included in the seventh indication message is one, then the determined serving cells all use the same seventh duration as the duration for skipping PDCCH monitoring; if multiple seventh durations are included, then according to the cell groups corresponding to different seventh durations, the seventh durations corresponding to different cell groups are respectively determined, and different seventh durations are used as the duration for skipping PDCC monitoring in different cell groups.

[0302] Step 74: The terminal device receives the eighth indication message sent by the network device corresponding to the primary serving cell PCell during the DRX inactivity time; among them, the eighth indication message includes: the duration for skipping PDCCH monitoring is the eighth duration.

[0303] In this step, if all DRX groups correspond to the same DRX configuration parameters, that is, the activation or deactivation times are the same, then the DRX deactivation time can be the deactivation time of all cell groups;

[0304] Or, it can be the deactivation time of the cell group where the primary serving cell is located;

[0305] Or, it can be the deactivation time of the DRX group corresponding to the cell group where the primary serving cell is located.

[0306] That is, the UE receives the WUS indicating PDCCH skipping information from the PCell at the DRX inactive time, which includes the PDCCH skipping duration, that is, the duration for which the UE does not monitor the PDCCH.

[0307] The indication information in step 21 or step 31 can specifically be the eighth indication information in this example. In this step, the eighth indication information can be carried by a wake-up signal (WUS, WakeUp Signal).

[0308] In addition to the above-mentioned eighth duration, the eighth indication information can further include:

[0309] Whether each cell group corresponding to the DRX group where the primary serving cell PCell is located skips PDCCH monitoring;

[0310] Or,

[0311] Whether each cell group in all cell groups of the terminal device skips PDCCH monitoring.

[0312] That is, the terminal device receives the WUS indicating PDCCH skipping information (eighth indication information) from the PCell at the DRX inactive time (deactivation time). In addition to the above-mentioned eighth duration, it specifically further includes: using a bitmap method to respectively indicate whether each cell needs to skip the PDCCH. Specifically, it can be one of the following:

[0313] Indicating whether each cell group in the cell group corresponding to the DRX group where the PCell is located needs to skip the PDCCH;

[0314] Indicating whether each cell group in all cell groups of the network device needs to skip the PDCCH.

[0315] Further, in one case, it is indicated by a bitmap whether each cell group in the cell group corresponding to the PCell's DRX group needs to skip PDCCH.

[0316] For example, if the DRX group where the terminal device's PCell is located is DRX group 1, which corresponds to 3 cell groups, namely cell groups 1, 2, and 3, the first value in the bitmap indicates skipping PDCCH monitoring, the second value indicates not skipping PDCCH monitoring, the first value is 1, the second value is 0, or vice versa; different bit positions in the bitmap correspond to different cell groups; if the bitmap is 101, it can indicate that the cell group 1 of DRX group 1 skips PDCCH monitoring, all serving cells of cell group 2 of DRX group 1 do not skip PDCCH monitoring, and all serving cells of cell group 3 of DRX group 1 skip PDCCH monitoring.

[0317] The eighth indication information can indicate the same eighth duration for the same one or more cell groups that need to skip PDCCH monitoring, that is, all serving cells in these cell groups skip PDCCH monitoring using the same eighth duration;

[0318] Or,

[0319] The eighth indication information can include multiple eighth durations, and different eighth durations are used for different cell groups that skip PDCCH monitoring. For example, if there are two cell groups that skip PDCCH monitoring, two eighth durations can be indicated, and different cell groups correspond to different eighth durations. The specific corresponding method can be one-to-one correspondence in order.

[0320] In another case, it is indicated whether each cell group in all cell groups of the network device needs to skip PDCCH.

[0321] For example, if the terminal device corresponds to 4 cell groups, namely cell groups 1, 2, 3, and 4, the first value in the bitmap indicates skipping PDCCH monitoring, the second value indicates not skipping PDCCH monitoring, the first value is 1, the second value is 0, or vice versa; different bit positions in the bitmap correspond to different cell groups; if the bitmap is 1010, it can indicate that cell groups 1 and 3 skip PDCCH monitoring, and all serving cells of cell groups 2 and 4 do not skip PDCCH monitoring.

[0322] The eighth indication information can indicate the same eighth duration for the same one or more cell groups that need to skip PDCCH monitoring, that is, all serving cells in these cell groups skip PDCCH monitoring using the same eighth duration;

[0323] Or,

[0324] In the eighth indication information, multiple eighth time durations may be included, and different eighth time durations are used to correspond to different cell groups that skip PDCCH monitoring. For example, if there are two cell groups that skip PDCCH monitoring, then two eighth time durations may be indicated, and different cell groups correspond to different eighth time durations. The specific corresponding manner may be one-to-one correspondence in sequence.

[0325] Among them, what can be included in the eighth indication information is the specific time length of the eighth time duration. Or, the eighth indication information may only include relevant information of one or more eighth time durations. The specific description is the same as the foregoing example and will not be elaborated here.

[0326] Step 75: The terminal device determines the serving cell that skips PDCCH monitoring and the time range for skipping PDCCH monitoring according to the eighth indication information.

[0327] Specifically, the terminal device determines the serving cell that skips PDCCH monitoring according to the bitmap of the eighth indication information.

[0328] Determining the time range for skipping PDCCH monitoring includes one of the following:

[0329] The start time for skipping PDCCH monitoring is the next time unit after receiving the eighth indication information, and the duration for skipping PDCCH monitoring is the eighth time duration; that is, the PDCCH skipping duration, which means the eighth time duration during which the UE does not monitor the PDCCH. Then, the terminal device starts from the next symbol after completing the PDCCH reception and does not monitor the PDCCH on the serving cells corresponding to all cell groups that need to skip the PDCCH within the subsequent PDCCH skipping duration.

[0330] Or,

[0331] The start time for skipping PDCCH monitoring is the moment when the next DRX continuous timer starts, and the duration for skipping PDCCH monitoring is the eighth time duration.

[0332] The specific processing manner of the time range for skipping PDCCH monitoring is similar to that in Example 1 and will not be elaborated here.

[0333] In addition, if the eighth indication information only includes one eighth duration, then the terminal device uses the same eighth duration as the duration for skipping PDCCH monitoring in all service cell groups determined not to perform PDCCH monitoring; if the eighth indication information includes multiple eighth durations, then the terminal device uses different eighth durations as the durations for skipping PDCCH monitoring corresponding to different service cell groups in the service cell groups determined not to perform PDCCH monitoring.

[0334] In one example, in a CA scenario, for a UE configured with one or more DRX groups, the service cells corresponding to each DRX group are grouped. The network can send a PDCCH on any one of the service cells to indicate to the UE to perform PDCCH skipping in one or more of the cell groups, and the PDCCH skipping ondurations corresponding to the at least one cell group that requires PDCCH skipping are the same.

[0335] Combined Figure 13 , the solution of this example is described exemplarily. Assume that the terminal device has two cell groups, namely cell group 1 and cell group 2. Cell group 1 includes a PCell and an SCell 1, and cell group 2 includes SCell2 and 3. In one DRX cycle, within the DRX active time, the terminal device receives the seventh indication information -1 carried by the PDCCH sent by the network device of SCell1 in cell group 1, which indicates that PDCCH skipping is only performed in cell group 1 and the seventh duration -1. Then the terminal device determines that PDCCH skipping is performed for all service cells in cell group 1, and determines the time range for skipping PDCCH monitoring as: starting from the next symbol of this seventh indication information -1, with a duration of the seventh duration -1. Within the DRX active time of the other cell group 2, the terminal device receives the seventh indication information -2 sent by the network device of SCell 3 in cell group 2, which indicates that PDCCH skipping is only performed in cell groups 1 and 2 and the seventh duration -1. Then the terminal device determines that PDCCH skipping is performed for all service cells in cell groups 1 and 2, and determines the time range for skipping PDCCH monitoring as: starting from the next symbol of this seventh indication information -2, with a duration of the seventh duration -2.

[0336] When the terminal device receives, during the DRX inactivity time, the eighth indication information carried by the WUS sent by the network device of the primary serving cell (PCell), where the eighth duration is indicated, the terminal device determines to skip PDCCH for all serving cells corresponding to the cell group where the primary serving cell is located, and determines the time range for skipping PDCCH monitoring as: at the moment when the next DRX continuous timer starts after the eighth indication information, with a duration of the eighth duration.

[0337] It can be seen that by adopting the above solution, in the CA scenario, a processing solution is provided for the terminal device to determine to skip PDCCH monitoring for some cells among all serving cells for some duration according to the indication information, thereby clearly providing a processing method for skipping PDCCH monitoring in the CA scenario processing, and further being able to reduce unnecessary PDCCH blind detections in the CA scenario, and thus saving terminal energy consumption.

[0338] An embodiment of the present invention provides a terminal device, as Figure 14 shown, including:

[0339] A first communication unit 81, which receives indication information;

[0340] Wherein, the indication information is used to determine to skip PDCCH monitoring during at least part of the duration of the discontinuous reception (DRX) activation time of at least some of all serving cells;

[0341] Wherein, all the serving cells include: the primary serving cell (PCell, Primary cell) of the terminal device, and N activated secondary serving cells (SCell, Secondary cell), where N is an integer greater than or equal to 1.

[0342] Correspondingly, a network device, as Figure 15 shown, includes:

[0343] A second communication unit 91, which sends indication information;

[0344] Wherein, the indication information is used to determine to skip physical downlink control channel (PDCCH) monitoring during at least part of the duration of the discontinuous reception (DRX) activation time of at least some of all serving cells;

[0345] Wherein, all the serving cells include: the primary serving cell (PCell, Primary cell) of the terminal device, and N activated secondary serving cells SCell, where N is an integer greater than or equal to 1.

[0346] Embodiments of the present invention are applicable to the CA scenario, especially to the CA scenario of 5G New Radio (NR). The description of CA has been provided above and will not be repeated here.

[0347] In this embodiment, the terminal device may further include:

[0348] A first processing unit 82, which determines the serving cell for skipping PDCCH monitoring and the time range for skipping PDCCH monitoring according to the indication information.

[0349] Based on the above description, combined with the following multiple examples, for different contents of the indication information or different serving cells for sending the indication information, how to determine the serving cell for skipping PDCCH monitoring and how to determine the time range for skipping PDCCH monitoring will be described respectively:

[0350] Example 1

[0351] The first communication unit 81 of the terminal device receives the configuration information sent by the network device; correspondingly, the second communication unit 91 of the network device sends the configuration information to the terminal device. Wherein, the configuration information may be RRC configuration information.

[0352] Among them, the RRC configuration information may include parameters for configuring DRX, parameters related to SCell, and parameters related to PDCCH skipping, etc. Specifically, the RRC configuration information may include at least one of the following:

[0353] 1) DRX configuration parameters, which may include: long DRX cycle, drx-onDurationTimer, drx-InactivityTimer, etc.; the content and related functions included in the DRX configuration parameters have been described in detail in the foregoing embodiments and will not be repeated here.

[0354] 2) The SCell configuration parameters at least include the SCell Index.

[0355] 3) For the PCell and each SCell, configure at least one DL BWP, and configure at least one PDCCH search space for at least one of the DL BWPs.

[0356] 4) The available duration for the terminal device to support skipping PDCCH monitoring. That is to say, the network device can configure at least one supported PDCCH skipping duration value for the terminal device, that is, the duration for which the PDCCH can indicate that the UE does not monitor the PDCCH.

[0357] The first communication unit 81 of the terminal device receives first indication information sent by the network device corresponding to the first serving cell within the DRX active time; wherein, the first indication information includes: the duration for skipping PDCCH monitoring is a first duration.

[0358] Wherein, the first serving cell is one of the PCell of the terminal device and N SCell in the active state.

[0359] The first indication information can be carried by the PDCCH.

[0360] Correspondingly, the second communication unit 91 of the network device corresponding to the first serving cell of the terminal device sends the first indication information to the terminal device within the DRX active time of the terminal device.

[0361] The first serving cell can be understood as any one of all the serving cells of the terminal device.

[0362] The first processing unit 82 of the terminal device determines to skip PDCCH monitoring for all the serving cells of the terminal device according to the first indication information, and determines that the start time of skipping PDCCH monitoring is the next time unit after receiving the first indication information, and the duration for skipping PDCCH monitoring is the first duration.

[0363] The first communication unit 81 of the terminal device receives second indication information sent by the network device corresponding to the primary serving cell PCell within the DRX non-active time; wherein, the second indication information includes: the duration for skipping PDCCH monitoring is a second duration.

[0364] The first processing unit 82 of the terminal device determines the serving cells for skipping PDCCH monitoring and the time range for skipping PDCCH monitoring according to the second indication information.

[0365] Specifically, the serving cells for skipping PDCCH monitoring are all the serving cells of the terminal device skipping PDCCH monitoring.

[0366] The time range for skipping PDCCH monitoring is one of the following:

[0367] The start time of skipping PDCCH monitoring is the next time unit after receiving the second indication information, and the duration for skipping PDCCH monitoring is the second duration;

[0368] Or,

[0369] The start time of skipping PDCCH monitoring is at the moment when the next DRX continuous timer starts, and the duration for skipping PDCCH monitoring is the second duration.

[0370] Example 2

[0371] The first communication unit 81 of the terminal device receives the configuration information sent by the network device; correspondingly, the second communication unit 91 of the network device sends the configuration information to the terminal device. Among them, the configuration information may be RRC configuration information.

[0372] Among them, the RRC configuration information may include parameters for configuring DRX-related parameters, SCell-related parameters, and PDCCH skipping-related parameters, etc. Specifically, the RRC configuration information may include at least one of the following:

[0373] 1) DRX configuration parameters, which may include: configuring multiple DRX groups for a MAC entity of the terminal device (in one example, 2 DRX groups may be configured), and the relevant configuration parameters corresponding to all DRX groups. Different DRX groups may correspond to different relevant configuration parameters. For example, 2 DRX groups may respectively correspond to different drx-InactivityTimer and / or drx-onDurationTimer configurations, etc.

[0374] 2) The SCell configuration parameters at least include the SCell Index (index);

[0375] 3) For the PCell and each SCell, configure at least one DL BWP, and configure at least one PDCCH search space for at least one of the DL BWPs;

[0376] 4) The available duration for skipping PDCCH monitoring supported by the terminal device. That is to say, the network device may configure at least one supported PDCCH skipping duration value for the terminal device, that is, the duration during which the PDCCH can indicate that the UE does not monitor the PDCCH;

[0377] 5) The corresponding relationship between different DRX groups and serving cells among all DRX groups. Specifically, it may include the corresponding relationship between each SCell and the DRX group. Different SCells are respectively corresponding to one of the 2 configured DRX groups. In addition, the PCell is defaultly corresponding to DRX group 1.

[0378] The first communication unit 81 of the terminal device receives the third indication information sent by the network device corresponding to the second serving cell within the activation time of the first DRX group; among them, the third indication information includes: the duration for skipping PDCCH monitoring is the third duration;

[0379] Among them, the second serving cell is one of the serving cells included in the first DRX group; the first DRX group is one of the multiple DRX groups of the terminal device.

[0380] Correspondingly, the second communication unit 91 of the network device corresponding to the second serving cell of the terminal device sends third indication information to the terminal device within the DRX activation time of the first DRX group of the terminal device.

[0381] The first processing unit 82 of the terminal device determines to skip PDCCH monitoring for all the serving cells included in the first DRX group according to the third indication information, and determines that the start time of skipping PDCCH monitoring is the next time unit after receiving the third indication information, and the duration of skipping PDCCH monitoring is the third duration.

[0382] The first communication unit 81 of the terminal device receives fourth indication information sent by the network device corresponding to the primary serving cell (PCell) during the non-active time of the second DRX group; among them, the fourth indication information includes: the duration of skipping PDCCH monitoring is the fourth duration.

[0383] The first processing unit 82 of the terminal device determines the serving cells for which PDCCH monitoring is skipped and the time range for skipping PDCCH monitoring according to the fourth indication information.

[0384] Specifically, the terminal device determining the serving cells for which PDCCH monitoring is skipped according to the fourth indication information may include one of the following situations:

[0385] Situation 1: The terminal device determines, according to the fourth indication information, that the serving cells for which PDCCH monitoring is skipped are all serving cells. That is, the terminal device does not monitor PDCCH on all serving cells during the subsequent PDCCH skipping duration (the fourth duration).

[0386] Or,

[0387] Situation 2: The terminal device determines, according to the fourth indication information, that the serving cells for which PDCCH monitoring is skipped are all serving cells within the second DRX group corresponding to the primary serving cell. That is, the terminal device does not monitor PDCCH on all serving cells corresponding to DRX group 1 (i.e., the second DRX group corresponding to the PCell) during the subsequent PDCCH skipping duration (the fourth duration).

[0388] Or,

[0389] Situation 3:

[0390] The fourth indication information further includes: a target DRX group that skips PDCCH monitoring in all DRX groups.

[0391] Correspondingly, a first processing unit 82 of the terminal device determines to skip PDCCH monitoring for all serving cells within the target DRX group according to the fourth indication information.

[0392] The specific processing method for the time range of skipping PDCCH monitoring is similar to that in Example 1 and will not be elaborated here.

[0393] Example 3

[0394] A first communication unit 81 of the terminal device receives configuration information sent by the network device; correspondingly, a second communication unit 91 of the network device sends configuration information to the terminal device. The configuration information may be RRC configuration information.

[0395] The RRC configuration information may include parameters for configuring DRX, parameters related to SCell, and parameters related to PDCCH skipping, etc. Specifically, the RRC configuration information may include at least one of the following:

[0396] 1) DRX configuration parameters, which may include: configuring multiple DRX groups for a MAC entity of the terminal device (in one example, 2 DRX groups may be configured), and related configuration parameters corresponding to all DRX groups. Different DRX groups may correspond to different related configuration parameters. For example, the 2 DRX groups may respectively correspond to different drx-InactivityTimer and / or drx-onDurationTimer configurations, etc.

[0397] 2) The SCell configuration parameters at least include the SCell Index (index);

[0398] 3) For the PCell and each SCell, configure at least one DL BWP, and configure at least one PDCCH search space for at least one of the DL BWPs;

[0399] 4) The available duration that the terminal device supports for skipping PDCCH monitoring. That is to say, the network device can configure at least one supported PDCCH skipping duration value for the terminal device, that is, the duration that the PDCCH can indicate that the UE does not monitor the PDCCH;

[0400] 5) The corresponding relationships between different DRX groups and serving cells among all the DRX groups. Specifically, it may include the corresponding relationship between each SCell and a DRX group, where different SCells are respectively mapped to one of the two configured DRX groups. Additionally, the PCell is defaultly mapped to DRX group 1. Among them, different DRX groups include different serving cells.

[0401] 6) Cell grouping information for PDCCH skipping indication: For each DRX group, group the serving cells corresponding to this DRX group to establish a mapping relationship between the serving cells and cell groups, that is, the corresponding relationship between each serving cell in each DRX group and a cell group. Among them, each serving cell is mapped to one of the cell groups, and different cell groups include different serving cells.

[0402] The first communication unit 81 of the terminal device receives the fifth indication information sent by the network device corresponding to the third serving cell within the DRX activation time of the first cell group; wherein, the fifth indication information includes: the duration of skipping PDCCH monitoring is the fifth duration.

[0403] Among them, the third serving cell is one of the serving cells included in the first cell group.

[0404] The first processing unit 82 of the terminal device determines to skip PDCCH monitoring for all the serving cells included in the first cell group according to the fifth indication information, and determines that the start time of skipping PDCCH monitoring is the next time unit after receiving the fifth indication information, and the duration of skipping PDCCH monitoring is the fifth duration.

[0405] The first communication unit 81 of the terminal device receives the sixth indication information sent by the network device corresponding to the primary serving cell PCell within the DRX non - activation time; wherein, the sixth indication information includes: the duration of skipping PDCCH monitoring is the sixth duration.

[0406] The first processing unit 82 of the terminal device determines the serving cells for which PDCCH monitoring is skipped and the time range for skipping PDCCH monitoring according to the sixth indication information.

[0407] Specifically, the serving cells for which the terminal device determines to skip PDCCH monitoring according to the fourth indication information may include one of the following situations:

[0408] Case 1: The terminal device determines, according to the sixth indication information, that the serving cells for which PDCCH monitoring is skipped are all serving cells. That is, the UE does not monitor PDCCH on all serving cells during the subsequent PDCCH skipping duration.

[0409] Or,

[0410] Case 2: The terminal device determines, according to the sixth indication information, that the serving cells for which PDCCH monitoring is skipped are all serving cells within the second cell group corresponding to the primary serving cell. That is, the UE does not monitor PDCCH on all serving cells corresponding to the cell group where the PCell is located during the subsequent PDCCH skipping duration.

[0411] It should be noted here that the second cell group may be the same as or different from the aforementioned first cell group. That is, if the first cell group is a group containing the primary serving cell, then the first cell group is the same as the second cell group; otherwise, they are different.

[0412] Or,

[0413] Case 3:

[0414] In the sixth indication information, it further includes: the target cell group for which PDCCH monitoring is skipped in all cell groups.

[0415] Correspondingly,

[0416] The first processing unit 82 of the terminal device determines, according to the sixth indication information, to skip PDCCH monitoring for all serving cells within the target cell group.

[0417] The specific processing method for the time range of skipping PDCCH monitoring is similar to that in Example 1 and will not be elaborated here.

[0418] Example 4:

[0419] The first communication unit 81 of the terminal device receives the configuration information sent by the network device; correspondingly, the network device sends configuration information to the terminal device. Among them, the configuration information may be RRC configuration information.

[0420] Among them, the RRC configuration information may include parameters for configuring DRX, parameters related to SCell, and parameters related to PDCCH skipping, etc. Specifically, the RRC configuration information may include at least one of the following:

[0421] 1) DRX configuration parameters may include: configuring multiple DRX groups for a MAC entity of a terminal device (in one example, 2 DRX groups may be configured), and related configuration parameters corresponding to all DRX groups. Different DRX groups may correspond to different related configuration parameters. For example, 2 DRX groups may respectively correspond to different drx-InactivityTimer and / or drx-onDurationTimer configurations, etc.

[0422] 2) The SCell configuration parameters at least include the SCell Index;

[0423] 3) For the PCell and each SCell, configure at least one DL BWP, and configure at least one PDCCH search space for at least one of the DL BWPs;

[0424] 4) The available duration that the terminal device supports for skipping PDCCH monitoring. That is to say, the network device can configure at least one supported PDCCH skipping duration value for the terminal device, that is, the duration during which the PDCCH can indicate that the UE does not monitor the PDCCH;

[0425] 5) The corresponding relationship between different DRX groups and serving cells among all the DRX groups. Specifically, it may include the corresponding relationship between each SCell and the DRX group. Different SCells are respectively mapped to one of the 2 configured DRX groups. In addition, the PCell is defaultly mapped to DRX group 1.

[0426] 6) Cell grouping information for PDCCH skipping indication: For each DRX group, group the serving cells corresponding to the DRX group, and establish a mapping relationship between the serving cells and the cell groups, that is, the corresponding relationship between each serving cell in each DRX group and the cell group. Among them, each serving cell corresponds to one of the cell groups, and different cell groups contain different serving cells.

[0427] The first communication unit 81 of the terminal device receives the seventh indication information sent by the network device corresponding to the fourth serving cell during the DRX activation time; wherein, the seventh indication information includes: the duration for skipping PDCCH monitoring is the seventh duration;

[0428] Wherein, the fourth serving cell is one of all the serving cells of the terminal device.

[0429] The seventh indication information further includes:

[0430] Whether each serving cell group in all the serving cell groups skips PDCCH monitoring;

[0431] Or

[0432] Whether each cell group corresponding to the DRX group where the fourth serving cell is located skips PDCCH monitoring.

[0433] The first processing unit 82 of the terminal device determines the serving cell that skips PDCCH monitoring and the time range for skipping PDCCH monitoring according to the seventh indication information.

[0434] In this example, the time range for determining to skip PDCCH monitoring is from the first time unit after receiving the fifth indication information, with a duration of the seventh duration.

[0435] Among them, the time unit can be symbol, and of course it can also be other time units, such as slot, etc., which are not enumerated here.

[0436] The first communication unit 81 of the terminal device receives the eighth indication information sent by the network device corresponding to the primary serving cell PCell during the DRX inactive time; among them, the eighth indication information includes: the duration for skipping PDCCH monitoring is the eighth duration.

[0437] In this step, if all DRX groups correspond to the same DRX configuration parameters, that is, the active or inactive times are the same, then the DRX inactive time can be the inactive time of all cell groups;

[0438] Or, it can be the inactive time of the cell group where the primary serving cell is located;

[0439] Or, it can be the inactive time of the DRX group corresponding to the cell group where the primary serving cell is located.

[0440] That is, the UE receives the WUS indication PDCCH skipping information from the PCell during the DRX inactive time, which includes the PDCCH skipping duration, that is, the duration for which the UE does not monitor the PDCCH.

[0441] In addition to the above-mentioned eighth duration, the eighth indication information may further include:

[0442] Whether each cell group corresponding to the DRX group where the primary serving cell PCell is located skips PDCCH monitoring;

[0443] Or

[0444] Whether each cell group in all cell groups of the terminal device skips PDCCH monitoring.

[0445] The first processing unit 82 of the terminal device determines the serving cell for skipping PDCCH monitoring and the time range for skipping PDCCH monitoring according to the eighth indication information.

[0446] Specifically, the terminal device determines the serving cell for skipping PDCCH monitoring according to the bitmap of the eighth indication information.

[0447] Determining the time range for skipping PDCCH monitoring includes one of the following:

[0448] The start time for skipping PDCCH monitoring is the next time unit after receiving the eighth indication information, and the duration for skipping PDCCH monitoring is the eighth duration; that is, the PDCCH skipping duration, which means the UE does not monitor the PDCCH for the eighth duration. Then, the terminal device starts from the next symbol after completing the PDCCH reception and does not monitor the PDCCH on the serving cells corresponding to all cell groups that need to skip the PDCCH within the subsequent PDCCH skipping duration.

[0449] Or,

[0450] The start time for skipping PDCCH monitoring is at the moment when the next DRX on-duration timer starts, and the duration for skipping PDCCH monitoring is the eighth duration.

[0451] The specific processing method for the time range of skipping PDCCH monitoring is similar to that in Example 1 and will not be elaborated here.

[0452] It can be seen that by adopting the above solution, in the CA scenario, a processing solution is provided for the terminal device to determine to skip PDCCH monitoring for a partial duration in some of all serving cells according to the indication information, thereby clearly providing a processing method for skipping PDCCH monitoring in the CA scenario processing, and further being able to reduce unnecessary PDCCH blind detections in the CA scenario, and thus saving the terminal energy consumption.
