Detailed Description

So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The technical scheme of the embodiment of the application can be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, an LTE Frequency Division Duplex (FDD) System, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication System, or a 5G System.

For example, a communication system 100 applied in the embodiment of the present application may be as shown in fig. 1-1. The communication system 100 may include a network device 110, and the network device 110 may be a device communicating with a UE120 (or referred to as a communication terminal device, a terminal device). Network device 110 may provide communication coverage for a particular geographic area and may communicate with UEs located within that coverage area. Optionally, the Network device 110 may be a Base Transceiver Station (BTS) in a GSM system or a CDMA system, a Network device (NodeB, NB) in a WCDMA system, an evolved Node B (eNB or eNodeB) in an LTE system, or a wireless controller in a Cloud Radio Access Network (CRAN), or a Network device in 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 Public Land Mobile Network (PLMN) for future evolution, or the like.

The communication system 100 also includes at least one UE120 located within the coverage area of the network device 110. "UE" as used herein includes, but is not limited to, connections via wireline, such as Public Switched Telephone Network (PSTN), digital Subscriber Line (DSL), digital cable, direct cable connection; and/or another data connection/network; and/or via a Wireless interface, e.g., for a cellular Network, a Wireless Local Area Network (WLAN), a digital television Network such as a DVB-H Network, a satellite Network, an AM-FM broadcast transmitter; and/or another UE's device configured to receive/transmit communication signals; and/or Internet of Things (IoT) devices. A UE arranged to communicate over a radio interface may be referred to as a "wireless communication terminal device", a "wireless terminal device" or a "mobile terminal device".

Optionally, terminal-to-Device (D2D) communication may be performed between the UEs 120.

It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

The scheme provided by the embodiment of the invention can be suitable for a CA scene, and specifically comprises the following steps:

in order to provide a larger data transmission rate and improve user experience, the 5G NR further increases the system bandwidth on the basis of 4G. In 5G NR, the maximum bandwidth supported by a single carrier is 100MHz for a frequency band below 6 GHz; for the frequency band above 6GHz, the maximum bandwidth supported by the single carrier is 400MHz. Like the LTE system, the 5G NR also supports the CA technology. For a terminal supporting the CA feature, the network RRC may configure one or more scells for the terminal in addition to one PCell. The terminal can simultaneously transmit and receive data on the PCell and the activated SCell(s), thereby improving the data transmission rate.

Wherein, the SCell has two states of activation and non-activation. Only when the SCell is in the active state, the terminal can transmit and receive data on this SCell. For a configured SCell, its initial state is inactive. Activation/deactivation of scells may be achieved in at least one of two ways: SCell activation/deactivation based on SCell activation/deactivation MAC CE indication; SCell deactivation based on timer timeout.

On the other hand, for a large carrier bandwidth, such as 100HMz, the bandwidth required by the terminal device is often very limited, and if the terminal is allowed to detect and measure the whole bandwidth all the time, it will bring a great challenge to the power consumption of the terminal, which is not favorable for saving power of the terminal. Therefore, the 5G NR introduces the concept of Bandwidth Part (BWP), that is, a Part of continuous Bandwidth is divided within the whole large Bandwidth carrier to transmit and receive data to and from the terminal. The terminal only needs to perform relevant operations in the part of the bandwidth configured by the network, thereby achieving the effect of saving energy of the terminal. Based on the 5G NR Rel-15 standard, the network RRC may configure one or more BWPs for the terminal on each serving cell of the terminal, with a maximum configurable number of BWPs of 4. At each time, the terminal can only have 1 active DownLink (DL) BWP and 1 active UpLink (UL) BWP in the serving cell, and the terminal can only perform data transceiving on the active BWP.

The terminal acquires the downlink or uplink scheduling information by receiving the PDCCH sent by the network, thereby further completing the receiving and sending of the service data. The time when the network schedules the terminal is not fixed, and the terminal needs to blindly detect the PDCCH because no related signaling informs the terminal whether the network sends the PDCCH to the terminal. In order to reduce the complexity of blind detection of the terminal, the set of blind detection PDCCHs needs to be restricted. Therefore, the concept of a search space, i.e., a PDCCH resource set that the terminal needs to detect blindly, is introduced. The network may configure one or more PDCCH search spaces for each BWP of the terminal. The terminal monitors the PDCCH only on the PDCCH search space corresponding to the currently activated BWP, thereby completing the transceiving of data.

Further, in the solution of this embodiment, the terminal device needs to be a terminal device configured with a DRX function. DRX in the 5G NR is explained as follows:

in the 5G NR, the network may configure a DRX function for the terminal, so that the terminal discontinuously monitors the PDCCH to achieve the purpose of saving power for the terminal. Each Media Access Control (MAC) entity has a corresponding DRX configuration, and a configuration parameter of the DRX includes at least one of:

-DRX-onDurationTimer (DRX-on duration timer) duration of UE wake-up at the beginning of one DRX Cycle;

-DRX-SlotOffset (DRX slot offset) time delay for the UE to start DRX-onDurationTimer;

-DRX-inactivity timer, wherein when the UE receives a PDCCH indicating an uplink initial transmission or a downlink initial transmission, the UE continues to monitor the duration of the PDCCH;

-DRX-retransmission timerdl (DRX-downlink DL retransmission timer) UE monitors the longest duration of PDCCH indicating downlink retransmission scheduling. Each downlink HARQ process except the broadcast HARQ process corresponds to one drx-retransmission TimerDL;

-DRX-retransmission timerll (DRX-uplink retransmission timer) UE monitors the longest duration of PDCCH indicating uplink retransmission scheduling. Each uplink HARQ process corresponds to one drx-retransmission TimerUL;

-DRX-Long Cycle startoffset (DRX-Long Cycle start offset) subframe offset for configuring Long DRX Cycle and start of Long DRX Cycle and Short DRX Cycle;

-DRX-Short cycle (DRX-Short cycle), which is an optional configuration;

DRX-ShortCycleTimer (DRX-Short cycle timer) the duration that the UE is in a Short DRX cycle (and does not receive any PDCCH), is an optional configuration;

-DRX-HARQ-RTT-TimerDL (DRX-HARQ-RTT downlink timer) UE expects to receive the minimum latency required for PDCCH indicating downlink scheduling, one DRX-HARQ-RTT-TimerDL for each downlink HARQ process except the broadcast HARQ process;

DRX-HARQ-RTT-timerll (DRX-HARQ-RTT uplink timer) the minimum latency required for a UE to expect to receive a PDCCH indicating uplink scheduling, one DRX-HARQ-RTT-timerll for each uplink HARQ process.

If the terminal configures DRX, the terminal needs to monitor PDCCH at DRX Active Time. DRX Active Time includes at least one of the following:

-any one of 5 timers of drx-onDurationTimer, drx-inactivytimeter, drx-retransmission timerdl, drx-retransmission timerll and ra-ContentionResolutionTimer is running;

-SR is sent on PUCCH and is in pending state;

-in a contention based random access procedure, the terminal has not received one initial transmission of the C-RNTI scrambled PDCCH indication after successful reception of the random access response.

With respect to the relationship between the DRX Cycle (Cycle) and the On Duration (Duration) of DRX and the terminal device monitoring the PDCCH, see fig. 1-2, wherein the terminal device performs PDCCH monitoring in DRX-On Duration. Specifically, the terminal determines the time for starting the DRX-onDurationTimer according to whether the terminal is currently in a short DRX cycle or a long DRX cycle, and the specific specification is as follows:

1> if Short DRX Cycle is used and the current subframe satisfies [ (SFN × 10) + subframe number ] module (DRX-Short) = (DRX-StartOffset) module (DRX-Short Cycle); or

1> if Long DRX Cycle is used and the current subframe satisfies [ (SFN × 10) + subframe number ] module (DRX-Long Cycle) = DRX-StartOffset;

2> at a time instant after drx-SlotOffset slots from the beginning of the current subframe, drx-onDurationTimer is started.

Based on the Rel-15 NR standard, each MAC entity corresponds to one DRX configuration. In the standardization process of NR Rel-16, one crdrx enhancement method in the NR CA scenario has been agreed at RAN2#108 conferences, i.e. a scheme where 2 DRX groups can be configured for one MAC entity. For this DRX enhancement method, the following explicit conclusions have been made:

the purpose of introducing the secondary DRX group is to configure different DRX groups for FR1 and FR 2;

for the secondary DRX group, the network may configure it with one DRX-inactivity timer and DRX-onduration timer. That is, the network configures DRX-inactivity timer and DRX-onDurationTimer for 2 DRX groups, respectively, and the rest DRX configuration parameters are common configuration parameters of the 2 DRX groups; and the number of the first and second groups,

cross-carrier scheduling between 2 DRX groups is not supported.

So that the manner in which the above recited features and aspects of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.

An embodiment of the present invention provides a monitoring control method, as shown in fig. 2, including:

step 21: the terminal equipment receives the indication information;

the indication information is used for determining that PDCCH monitoring is skipped in at least part of duration of Discontinuous Reception (DRX) activation time of at least part of all service cells;

wherein the total serving cells include: the serving cell configuration method includes a Primary serving cell (PCell) of the terminal device, and N Secondary serving cells (scells) in an activated state, where N is an integer greater than or equal to 1.

Correspondingly, the network device side also provides a monitoring control method, as shown in fig. 3, including:

step 31: the network equipment sends indication information;

wherein the total serving cells include: a Primary serving cell (PCell) of the terminal device, and N secondary serving cells scells in an activated state, where N is an integer greater than or equal to 1.

The embodiments of the present invention are applicable to a CA scenario, and in particular, to a CA scenario of a New 5G air interface (New Radio), and the description about CA is provided in the foregoing, and is not repeated here.

In this embodiment, after the terminal device receives the indication information, the method may include:

and the terminal equipment determines a service cell for skipping PDCCH monitoring and a time range for skipping PDCCH monitoring according to the indication information.

That is, the terminal device may further determine whether to perform the process of skipping PDCCH monitoring in all serving cells or perform the process of skipping PDCCH monitoring in only some serving cells of all serving cells according to the indication information; in addition, when the range of the serving cell is determined, the time range within which to skip the PDCCH monitoring can be further determined according to the indication information.

The skipping of PDCCH monitoring may specifically be understood as: stopping monitoring the PDCCH within the DRX activation time (or within the duration of the DRX On); alternatively, it can be understood that the PDCCH is not monitored during the DRX active time.

Based on the above description, how to determine the serving cell skipping PDCCH monitoring and how to determine the time range skipping PDCCH monitoring are described for the case of different contents of the indication information or different serving cells transmitting the indication information, respectively, in conjunction with the following multiple examples:

examples 1, 1,

The specific processing procedure, as shown in fig. 4, includes the following steps:

step 41, the terminal device receives configuration information sent by the network device; correspondingly, the network equipment sends configuration information to the terminal equipment. Wherein the configuration information may be RRC configuration information.

The RRC configuration information may include relevant parameters for configuring a DRX, SCell, PDCCH clipping, and the like. Specifically, the RRC configuration information may include at least one of:

1) The DRX configuration parameters may include: long DRX cycle (long DRX cycle), DRX-on duration timer, DRX-inactivity timer, etc.; the details of the DRX configuration parameters and the related actions are already described in the foregoing embodiments, and are not repeated herein.

2) The SCell configuration parameter contains at least SCell Index;

3) Configuring at least one DL BWP for the PCell and each SCell, and configuring at least one PDCCH search space for the at least one DL BWP;

4) And skipping the available duration of PDCCH monitoring supported by the terminal equipment. That is, the network device may configure at least one supportable PDCCH blanking duration value for the terminal device, i.e. a time duration that the PDCCH may indicate that the UE does not monitor the PDCCH.

It should be noted that, in this step, the network device may be a network device of a serving cell to which the terminal device is currently connected, for example, the network device may be a network device corresponding to a main serving cell of the terminal device.

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

The available duration supported by the terminal device to skip PDCCH monitoring may specifically include: skipping an available duration of PDCCH monitoring supported by one or more of the terminal devices. In addition, the duration of the available duration for skipping PDCCH monitoring may be greater than the duration of DRX on (or the length of DRX active time), or may be not greater than the duration of DRX on (or the length of DRX active time), which is not limited in this embodiment.

Based on the configuration of this step, step 42 or step 44 may be performed later depending on whether the terminal device is within the DRX active time; the terminal device is in DRX active time, step 42 is performed, and if the terminal device is in DRX inactive time, step 44 is performed, respectively.

Step 42, the terminal device receives first indication information sent by a network device corresponding to a first serving cell within DRX activation time; wherein, the first indication information includes: the duration of skipping PDCCH monitoring is a first duration;

wherein the first serving cell is one of a PCell of the terminal device and N SCells in an active state.

That is, the indication information in step 21 or step 31 may be specifically the first indication information in this example. In this step, the first indication information may be carried by a PDCCH.

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.

The first serving cell may be understood as any one of all serving cells of the terminal device.

The specific time length of the first duration may be included in the first indication information.

Still alternatively, the first indication information may only contain information related to one first duration. Specifically, since the available duration of skipping PDCCH monitoring supported by the terminal device(s) has been configured in step 41; the available durations of the different skipped PDCCH monitoring may correspond to different related information, for example, the related information may be an Index (Index) or a different number, or a different identifier. Accordingly, in this step, the first indication information may only include information (e.g., an index) related to one duration, so that the signaling overhead can be further reduced.

And 43, the terminal device determines to skip the PDCCH monitoring for all serving cells of the terminal device according to the first indication information, and determines that the starting time of skipping the PDCCH monitoring is the next time unit of receiving the first indication information, and the duration of skipping the PDCCH monitoring is a first duration.

That is to say, in this example, when receiving the first indication information sent by any one serving cell, the terminal device determines that the serving cell that skips PDCCH monitoring is all serving cells;

and determining that the time range for skipping the PDCCH monitoring is the first time duration from the first time unit after the first indication information is received.

The time unit may be symbol, and of course, may also be other time units, such as time slot (slot), and the like, which is not exhaustive here.

The above steps 42 to 43 are combined, and the time unit is symbol: the terminal device receives PDCCH blanking information (that is, carries first indication information) indicated by a PDCCH from any serving cell in DRX active time (activation time), where the PDCCH blanking information includes a first duration, for example, a PDCCH blanking duration, and the first duration is a duration in which the terminal device does not monitor the PDCCH;

the terminal device does not monitor the PDCCH on all serving cells for the following PDCCH blanking duration, starting with the next symbol that completes the PDCCH reception.

Step 44, the terminal device receives second indication information sent by a network device corresponding to a primary serving cell PCell within the DRX inactivity time; wherein the second indication information includes: and the duration of skipping the PDCCH monitoring is a second duration.

That is, the indication information in step 21 or step 31 may specifically be the second indication information in this example. In this step, the second indication information may be carried by a Wake Up Signal (WUS).

Correspondingly, in this step, the network device may be a network device corresponding to a primary serving cell PCell of the terminal device, and the network device sends the second indication information to the terminal device within the DRX inactivity time of the terminal device.

The specific time length of the second duration may be included in the second indication information.

Still alternatively, the second indication information may only contain information related to a second duration. Specifically, since the available duration of skipping PDCCH monitoring supported by the terminal device(s) has been configured in step 41; the available durations of the different skipped PDCCH monitoring may correspond to different related information, for example, the related information may be an Index (Index) or a different number, or a different identifier. Accordingly, in this step, the second indication information may only include information (such as an index) related to the second duration, so that the signaling overhead can be further reduced.

And step 45, the terminal equipment determines a serving cell for skipping the PDCCH monitoring and a time range for skipping the PDCCH monitoring according to the second indication information.

Specifically, the serving cell that skips the PDCCH monitoring for all serving cells of the terminal device.

That is, in the present example, the first indication information and the second indication information are directed to all the serving cells of the terminal device.

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

the starting time of skipping PDCCH monitoring is the next time unit of receiving the second indication information, and the duration of skipping PDCCH monitoring is a second duration;

or,

the starting time of skipping PDCCH monitoring is the time when the next DRX duration timer is started, and the duration of skipping PDCCH monitoring is the second duration.

With reference to step 44 and step 45, the following description is given by way of example:

the terminal equipment receives WUS indication PDCCH cropping information (second indication information) from a PCell at DRX inactive time (inactive time), wherein the second indication information comprises a second PDCCH cropping duration, namely a second time length for which the UE does not monitor the PDCCH;

the terminal device does not listen to PDCCH on all serving cells for the following PDCCH blanking duration. The determination of the starting time when the terminal device does not monitor the PDCCH includes the following two ways:

mode 1: the starting time of skipping the PDCCH monitoring is the next time unit of receiving the second indication information, and the duration of skipping the PDCCH monitoring is a second duration. That is, the terminal device does not monitor the PDCCH at the next symbol that the WUS that completes the scheduling receives, as shown in fig. 5.

Mode 2: the starting time of skipping PDCCH monitoring is the time when the next DRX duration timer is started, and the duration of skipping PDCCH monitoring is the second duration. That is, the terminal device does not monitor the PDCCH from the subsequent drx-ondurationtimer start time, as shown in fig. 6.

In one example, in a CA scenario, for a UE configured with DRX, the network may instruct the terminal device to skip PDCCH monitoring (PDCCH skiping) on all serving cells by transmitting a PDCCH on any one serving cell of the terminal device or transmitting a WUS indication on a PCell, and a time range (which may be referred to as PDCCH skiping on duration) for which the UE skips PDCCH monitoring on all serving cells is the same.

With reference to fig. 7, the scheme of this example is exemplarily described, assuming that the terminal device has one PCell, and three scells, which are respectively denoted as SCell1, 2, and 3; in a DRX Cycle (Cycle), the terminal device receives an indication a (i.e., a first indication information) carried by the PDCCH, which is sent by (the network device of) Scell2 within a DRX activation time, where the first duration-a is indicated, the terminal device determines to skip the PDCCH for all serving cells, and determines that a time range for skipping PDCCH monitoring is: starting at the next Symbol of the indication a, the duration is the first duration-a.

In another DRX Cycle (Cycle), the terminal device receives, within a DRX activation time, an indication B (i.e., another first indication information) carried by the PDCCH and sent by (the network device of) Scell1, where the first duration-B is indicated, and then the terminal device determines to skip the PDCCH for all serving cells, and determines that a time range for skipping PDCCH monitoring is: starting at the next Symbol of the indication B, the duration is the first duration-B.

The terminal equipment receives an indication C carried by the WUS from (network equipment of) a primary service cell PCell within the DRX inactive time, wherein the indication C indicates a second duration, the terminal equipment determines to skip the PDCCH for all service cells, and determines that the time range for skipping the PDCCH monitoring is as follows: and at the moment when the next DRX duration timer is started after the instruction C, the duration is the second duration.

Examples 2,

The specific implementation process, as shown in fig. 8, includes the following steps:

step 51, the terminal equipment receives configuration information sent by the network equipment; correspondingly, the network equipment sends configuration information for the terminal equipment. Wherein the configuration information may be RRC configuration information.

1) The DRX configuration parameters can comprise: multiple DRX groups (in an example, 2 DRX groups) are configured for one MAC entity of the terminal device, and related 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-inactivity timer and/or DRX-onDurationTimer configurations, and so on.

2) The SCell configuration parameter contains at least SCell Index;

4) And skipping the available duration of PDCCH monitoring supported by the terminal equipment. That is, the network device may configure at least one supportable PDCCH blanking duration value for the terminal device, that is, a duration that the PDCCH indicates that the UE does not monitor the PDCCH;

5) And the corresponding relation between different DRX groups in all DRX groups and the service cell. Specifically, a correspondence relationship between each SCell and a DRX group may be included, and different scells respectively correspond to one DRX group of 2 configured DRX groups. In addition, PCell corresponds to DRX group 1 by default.

It should be noted that, in this step, the network device may be a network device of a serving cell to which the terminal device is currently connected, for example, the network device may be a network device corresponding to a primary serving cell of the terminal device, and certainly, the network device may also be configured for the terminal device for an auxiliary serving cell in an active state, which is not limited herein.

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

Based on the configuration of this step, step 52 or step 54 may be performed later, depending on whether the terminal device is within the DRX activation time; the terminal device is in DRX active time, step 52 is performed, and if the terminal device is in DRX inactive time, step 54 is performed, respectively.

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

wherein the second serving cell is one of serving cells included in the first DRX group; the first DRX group is one of a plurality of DRX groups of the terminal equipment.

In this step, it may be understood that the terminal device may receive the third indication information sent from (the network device of) any serving cell corresponding to any DRX group in the activation time of any DRX group in the multiple DRX groups. For convenience of understanding only, any one of the DRX groups will be referred to as a first DRX group, and any one of the serving cells in the DRX group will be referred to as a second serving cell. The second serving cell may also be any one of a PCell or a Scell.

That is, the indication information in step 21 or step 31 may specifically be the third indication information in this example. In this step, the third indication information may be carried by the PDCCH.

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

The third indication information may include a specific time length of the first time length.

Still alternatively, the third indication information may only contain information related to a third duration. Specifically, since the available duration of skipping PDCCH monitoring supported by the terminal device(s) has been configured in step 51; the available durations of the different skipped PDCCH monitoring may correspond to different related information, for example, the related information may be an Index (Index) or a different number, or a different identifier. Accordingly, in this step, the third indication information may only include information (e.g., an index) related to one duration, so that the signaling overhead can be further reduced.

And step 53, the terminal device determines to skip the PDCCH monitoring for all the serving cells included in the first DRX group according to the third indication information, and determines that the starting time of skipping the PDCCH monitoring is the next time unit when the third indication information is received, and the duration of skipping the PDCCH monitoring is a third duration.

That is to say, in this example, when the terminal device receives the third indication information sent by any serving cell in any DRX group, it determines that the serving cell that skips PDCCH monitoring is all serving cells included in the DRX group;

The following steps 52 to 53 are described with the time unit symbol as an example:

for each DRX group, the terminal device receives PDCCH blanking information (third indication information) carried by a PDCCH indication from any one service cell corresponding to the DRX group at the active time of the DRX group, wherein the PDCCH blanking information comprises a PDCCH blanking duration (third duration), namely the third duration for which the UE does not monitor the PDCCH;

the terminal device starts at the next symbol that completes the PDCCH reception (i.e. completes the reception of the third indication information), and does not monitor the PDCCH on all serving cells corresponding to the DRX group for the following PDCCH blanking duration (the third duration).

Step 54, the terminal device receives fourth indication information sent by a network device corresponding to a primary serving cell PCell within the inactive time of the second DRX group; wherein, the fourth indication information includes: the duration of skipping the PDCCH monitoring is a fourth duration.

That is, the terminal device receives the WUS indication PDCCH blanking information (fourth indication information) from the PCell at a DRX inactive time (e.g., an inactive time of the second DRX group), which includes a PDCCH blanking duration (fourth time length), i.e., a time length during which the UE does not monitor the PDCCH.

The indication information in step 21 or step 31 may specifically be fourth indication information in this example. In this step, the fourth indication information may be carried by a Wake Up Signal (WUS).

Correspondingly, in this step, the network device may be a network device corresponding to a primary serving cell PCell of the terminal device, and the network device sends the fourth indication information to the terminal device within the DRX inactivity time of the terminal device.

The second DRX packet in this step may be a DRX packet in which the PCell is located. Correspondingly, the network device in this step may be a network device corresponding to the primary serving cell PCell, that is, a network device corresponding to the primary serving cell PCell, and send the fourth indication information to the terminal device within the inactive time of the second DRX group of the terminal device.

Wherein, what can be contained in the fourth indication information is the specific time length of the fourth duration.

Still alternatively, the fourth indication information may only contain the related information of a fourth duration. Specifically, since the available duration of skipping PDCCH monitoring supported by the terminal device(s) has been configured in step 51; the available durations of the different skipped PDCCH monitoring may correspond to different related information, for example, the related information may be an Index (Index) or a different number, or a different identifier. Accordingly, in this step, the fourth indication information may only include related information (such as an index) of the fourth duration, so that the signaling overhead can be further reduced.

And step 55, the terminal device determines, according to the fourth indication information, to skip the serving cell monitored by the PDCCH and to skip the time range monitored by the PDCCH.

Specifically, the determining, by the terminal device, the serving cell for skipping PDCCH monitoring according to the fourth indication information may include one of the following cases:

case 1: and the terminal equipment determines the service cells which skip the PDCCH monitoring as all the service cells according to the fourth indication information. That is, the terminal device does not monitor the PDCCH on all serving cells for the following PDCCH blanking duration (fourth duration).

Or,

case 2: and the terminal equipment determines the service cells skipping the PDCCH monitoring as all the service cells in a second DRX group corresponding to the main service cell according to the fourth indication information. That is, the terminal device does not monitor the PDCCH on all serving cells corresponding to DRX group 1 (i.e., the second DRX group corresponding to the PCell) for the following PDCCH blanking duration (the fourth duration).

Or,

case 3:

the fourth indication information further includes: and skipping the target DRX group monitored by the PDCCH in all DRX groups.

Correspondingly, determining a serving cell for skipping PDCCH monitoring according to the indication information includes:

and the terminal equipment determines to skip the PDCCH monitoring on all the service cells in the target DRX group according to the fourth indication information.

In this case, the fourth indication information may be in a bitmap (bitmap) manner, for example, there are two DRX groups, each bit corresponds to one DRX group, when the bit is set to the first value, the corresponding DRX group indicates that PDCCH monitoring is skipped, and when the bit is set to the second value, the corresponding DRX group indicates that PDCCH monitoring is not skipped. Wherein the first value may be 1 and the second value may be 0, or vice versa.

For example, two DRX groups, DRX group 1, DRX group 2, bitmap, include two bits, the first bit corresponds to DRX group 1, the second bit corresponds to DRX group 2, if 01 is indicated in the fourth indication information, it indicates that DRX group 2 is the target DRX group, and all serving cells in the DRX group (or corresponding to the DRX group) skip PDCCH monitoring.

That is, the network device indicates whether to skip the PDCCH for the serving cell of each DRX group by using bitmap through WUS (carried fourth indication information). The terminal device then indicates, based on the WUS, that the PDCCH is not monitored on all serving cells corresponding to the DRX group that requires a skiping PDCCH for a subsequent PDCCH skiping duration.

Determining a time range for skipping PDCCH monitoring, including one of:

the starting time of skipping PDCCH monitoring is the next time unit of receiving the fourth indication information, and the duration of skipping PDCCH monitoring is a fourth duration;

or,

the starting time of skipping PDCCH monitoring is the time when the next DRX duration timer is started, and the duration of skipping PDCCH monitoring is the fourth duration.

The specific processing manner for skipping the time range for PDCCH monitoring is similar to that in example 1, and is not described here again.

In one example, in a CA scenario, for a terminal device configured with multiple DRX groups (groups), for each DRX group, the network may instruct the terminal device to PDCCH skiping on all serving cells corresponding to the DRX group by sending a PDCCH on any one serving cell corresponding to the DRX group, where PDCCH skiping on all serving cells corresponding to the DRX group are the same.

With reference to fig. 9, the scheme of this example is exemplarily described, assuming that the terminal device has two DRX groups, i.e. DRX group 1 and DRX group 2, where DRX group 1 includes one PCell and one SCell1, DRX group 2 includes scells 2 and 3; in a DRX Cycle, the terminal equipment receives third indication information-A carried by a PDCCH and sent by (network equipment of) a main service cell PCell of a DRX group 1 in a DRX activation time, wherein the third duration-A is indicated, the terminal equipment determines that all service cells in the DRX group 1 carry out PDCCH skipping, and determines that the time range for skipping PDCCH monitoring is that the next Symbol of the third indication information-A starts, and the duration is the third duration-A.

In another DRX Cycle (Cycle), the terminal device receives, in a DRX activation time, third indication information B carried by the PDCCH and sent by (the network device of) Scell1, where a third duration-B is indicated, and then the terminal device determines that PDCCH skipping is performed for all serving cells of the DRX group 1, and determines that a time range for skipping PDCCH monitoring is: beginning at the next Symbol of the third indication message B, the duration is the third duration-B. In addition, when the terminal device receives the third indication information-C sent by (the network device of) SCell 3 in DRX group 2, the terminal device determines that PDCCH skipping is performed for all serving cells of DRX group 2, and determines that the time range for skipping PDCCH monitoring is: starting at the next Symbol of the third indication information C, the duration is the third duration-C.

The terminal device receives fourth indication information carried by the WUS from (the network device of) the primary serving cell PCell within the DRX inactivity time, where the fourth duration is indicated, the terminal device determines to skip the PDCCH for all serving cells, and determines that the time range for skipping PDCCH monitoring is: and at the moment when the next DRX duration timer is started after the fourth indication information, the duration is the fourth duration.

Examples 3,

The specific implementation process, as shown in fig. 10, includes the following steps:

step 61, the terminal equipment receives configuration information sent by the network equipment; correspondingly, the network equipment sends configuration information to the terminal equipment. Wherein the configuration information may be RRC configuration information.

The RRC configuration information may include relevant parameters for configuring DRX, SCell, and PDCCH clipping, etc. Specifically, the RRC configuration information may include at least one of:

1) The DRX configuration parameters may include: multiple DRX groups (in an example, 2 DRX groups) are configured for one MAC entity of the terminal device, 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 correspond to different DRX-inactivity timer and/or DRX-onduration timer configurations, respectively, and so on.

2) The SCell configuration parameter contains at least SCell Index;

5) And the corresponding relation between different DRX groups in all DRX groups and the service cell. Specifically, a correspondence relationship between each SCell and a DRX group may be included, and different scells respectively correspond to one DRX group of 2 configured DRX groups. In addition, PCell corresponds to DRX group 1 by default. Wherein different DRX groups comprise different serving cells.

6) Cell grouping information for PDCCH blanking indication: for each DRX group, grouping the service cells corresponding to the DRX group, and establishing a mapping relation between the service cells and the cell groups, namely the corresponding relation between each service cell in each DRX group and the cell groups. Wherein each cell corresponds to one of the cell groups, and the different cell groups contain different cells.

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

Based on the configuration of this step, step 62 or step 64 may be performed later depending on whether the terminal device is within the DRX active time; the terminal device is in DRX active time, step 62 is performed, and if the terminal device is in DRX inactive time, step 64 is performed, respectively.

Step 62, the terminal device receives fifth indication information sent by a network device corresponding to a 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 a fifth duration;

wherein the third serving cell is one of the serving cells included in the first cell group.

In this step, it may be understood that the terminal device may receive the fifth indication information sent from (the network device of) any serving cell corresponding to the cell group within the activation time of any cell group in the plurality of cell groups. For convenience of understanding only, any one of the DRX groups will be referred to as a first cell group, and any one of the serving cells in the cell group will be referred to as a third serving cell. The third serving cell may also be any one of a PCell or a Scell.

That is, the indication information in step 21 or step 31 may be specifically the fifth indication information in this example. In this step, the fifth indication information may be carried by the PDCCH.

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

The fifth indication information may include a specific time length of the fifth time length.

Still alternatively, the fifth indication information may only contain related information of a fifth duration. In particular, since the available duration of skipped PDCCH monitoring supported by the terminal device(s) has been configured in step 61; the available durations of the different skipped PDCCH monitoring may correspond to different related information, for example, the related information may be an Index (Index) or a different number, or a different identifier. Accordingly, in this step, the fifth indication information may only include the relevant information (such as an index) of one duration, so that the signaling overhead can be further reduced.

And step 63, the terminal device determines to skip the PDCCH monitoring for all the serving cells included in the first cell group according to the fifth indication information, and determines that the starting time of skipping the PDCCH monitoring is the next time unit when the fifth indication information is received, and the duration of skipping the PDCCH monitoring is a fifth duration.

That is to say, in this example, after receiving the fifth indication information sent by any serving cell in any cell group, the terminal device determines that the serving cells that skip the PDCCH monitoring are all the serving cells included in the cell group;

and determining that the time range for skipping the PDCCH monitoring is the first time unit after the fifth indication information is received, and the duration is the fifth duration.

The following steps 62 to 63 are described with the time unit symbol as an example:

for each cell group, the terminal device receives PDCCH indication PDCCH blanking information (fifth indication information) from any serving cell corresponding to the cell group at the active time of the DRX group corresponding to each cell group, where the PDCCH indication PDCCH blanking information includes PDCCH blanking duration, that is, the duration (fifth duration) for which the UE does not monitor the PDCCH, and the UE does not monitor the PDCCH on all serving cells corresponding to the cell group within the subsequent PDCCH blanking duration (fifth duration) from the next symbol received by the PDCCH.

Step 64, the terminal device receives sixth indication information sent by a network device corresponding to a primary serving cell PCell within the DRX inactivity time; wherein, the sixth indication information includes: the duration of skipping the PDCCH monitoring is the sixth duration.

In this step, the DRX inactivity time may be inactivity time of all cell groups, or may be inactivity time of a cell group in which the primary serving cell is located.

That is, the UE receives the WUS indication PDCCH blanking information including PDCCH blanking duration, i.e., the duration for which the UE does not monitor the PDCCH, from the PCell at the DRX inactive time.

The indication information in step 21 or step 31 may specifically be sixth indication information in this example. In this step, the sixth indication information may be carried by a Wake Up Signal (WUS).

Correspondingly, in this step, the network device may be a network device corresponding to a primary serving cell PCell of the terminal device, and the network device sends the sixth indication information to the terminal device within the DRX inactivity time of the terminal device.

Wherein, what can be contained in the sixth indication information is the specific time length of the fourth duration.

Still alternatively, the sixth indication information may only contain the related information of the fourth duration. The specific description is the same as the previous example and is not repeated.

And step 65, the terminal device determines, according to the sixth indication information, a serving cell for skipping PDCCH monitoring and a time range for skipping PDCCH monitoring.

Specifically, the determining, by the terminal device, to skip the serving cell monitored by the PDCCH according to the fourth indication information may include one of the following cases:

case 1: and the terminal equipment determines the serving cells which skip the PDCCH monitoring as all the serving cells according to the sixth indication information. I.e., the UE does not monitor the PDCCH on all serving cells for the following PDCCH blanking duration.

Or,

case 2: and the terminal equipment determines that the serving cell which skips the PDCCH monitoring is all the serving cells in the second cell group corresponding to the main serving cell according to the sixth indication information. That is, the UE does not monitor the PDCCH in all serving cells corresponding to the cell group where the PCell is located in the subsequent PDCCH puncturing duration.

It should be noted here that the second cell group may be the same as or different from the first cell group, that is, if the first cell group is a group including a primary serving cell, the first cell group is the same as the second cell group, otherwise, the first cell group is different from the second cell group.

Or,

case 3:

the sixth indication information further includes: and skipping target cell groups monitored by the PDCCH in all cell groups.

Accordingly, the method can be used for solving the problems that,

the method for the terminal equipment to skip the serving cell monitored by the PDCCH according to the indication information comprises the following steps:

and the terminal equipment determines to skip the PDCCH monitoring on all the serving cells in the target cell group according to the sixth indication information.

In this case, the sixth indication information may be in a bitmap (bitmap) manner, for example, there are 3 cell packets, each bit corresponds to one cell packet, when the bit is set to a first value, the corresponding cell packet is a target cell packet, the target cell packet skips PDCCH monitoring, and when the bit is set to a second value, the corresponding cell packet is characterized by not skipping PDCCH monitoring. Wherein the first value may be 1 and the second value may be 0, or vice versa.

That is, the WUS instructs the UE whether to skip PDCCH for each cell group separately using a bitmap approach. The UE indicates, based on the WUS, that the PDCCH is not monitored on all serving cells corresponding to a cell group requiring a skiping PDCCH for a subsequent PDCCH skiping duration.

Determining a time range for skipping PDCCH monitoring, including one of:

the starting time of skipping the PDCCH monitoring is the next time unit of receiving the fourth indication information, and the duration of skipping the PDCCH monitoring is a fourth duration;

or,

In one example, in a CA scenario, for a UE configured with one or more DRX groups, serving cells corresponding to each DRX group are grouped. For each cell group, the network may indicate the UE to PDCCH clipping 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 clipping durations of the UE on all serving cells are the same.

With reference to fig. 11, the scheme of this example is exemplarily explained, and it is assumed that the terminal device has two cell groups, which are

cell groups

1 and 2, respectively, where cell group 1 includes one PCell and one SCell1, and cell group 2 includes scells 2 and 3; in one DRX Cycle (Cycle), the terminal device receives, in DRX activation time, fifth indication information-1 carried by a PDCCH and sent by (the network device of) Scell1 of the cell group 1, where a fifth duration-1 is indicated, and then the terminal device determines that PDCCH skipping is performed for all serving cells of the cell group 1, and determines that a time range for skipping PDCCH monitoring is: starting at the next Symbol of the fifth indication message-1, the duration is the fifth duration-1. In the DRX activation time of another cell group 2, if the terminal device receives the fifth indication information-2 sent by (the network device of) the SCell 3 in the cell group 2, the terminal device determines to perform PDCCH skipping for all serving cells of the cell group 2, and determines that the time range for skipping PDCCH monitoring is: starting at the next Symbol of the fifth indication message-2, the duration is the fifth duration-2.

The terminal device receives sixth indication information carried by the WUS from (a network device of) a primary serving cell PCell within DRX inactivity time, where a sixth duration is indicated, and then the terminal device determines that PDCCH skipping is performed on all serving cells corresponding to a cell group in which the primary serving cell is located, and determines that a time range for skipping PDCCH monitoring is: and at the moment when the next DRX duration timer is started after the sixth indication information, the duration is the sixth duration.

Examples 4,

The specific implementation process, as shown in fig. 12, includes the following steps:

step 71, the terminal equipment receives configuration information sent by the network equipment; correspondingly, the network equipment sends configuration information to the terminal equipment. Wherein the configuration information may be RRC configuration information.

1) The DRX configuration parameters can comprise: multiple DRX groups (in an example, 2 DRX groups) are configured for one MAC entity of the terminal device, 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 correspond to different DRX-inactivity timer and/or DRX-onduration timer configurations, respectively, and so on.

2) The SCell configuration parameter contains at least SCell Index;

The content of the specific configuration in this step is the same as that in the foregoing example 3, and is not described again.

Based on the configuration of this step, step 72 or step 74 may be performed later, depending on whether the terminal device is within the DRX activation time; the terminal device is in DRX active time, step 72 is performed, and if the terminal device is in DRX inactive time, step 74 is performed, respectively.

Step 72, the terminal device receives, within the DRX activation time, seventh indication information sent by a network device corresponding to a fourth serving cell; wherein, the seventh indication information includes: skipping the PDCCH monitoring for a seventh time duration;

wherein the fourth serving cell is one of all serving cells of the terminal device.

In this step, the DRX activation time may be understood as that all DRX packets of the terminal device use the same DRX cycle, that is, all DRX packets enter the DRX On state at the same time, or enter the DRX activation time, and the duration of the DRX-On is the same.

Of course, the DRX activation time may also be the DRX activation time corresponding to the cell group in which the fourth serving cell is located, or the DRX activation time may also be the DRX activation time corresponding to the DRX group in which the fourth serving cell is located.

This step may be understood as that the terminal device may receive the seventh indication information sent from (the network device of) the any serving cell during the activation time. For convenience of understanding only, any one of the serving cells will be referred to as a fourth serving cell hereinafter. The fourth serving cell may be any one of a PCell or a Scell.

That is, the indication information in step 21 or step 31 may specifically be the seventh indication information in this example. In this step, the seventh indication information may be carried by the PDCCH.

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

Wherein, what can be contained in the seventh indication information is the specific time length of the fifth duration.

Still alternatively, the seventh indication information may only contain the related information of the fifth time period. The detailed description is similar to the previous example and is not repeated here.

In addition, unlike the foregoing example, the seventh indication information further includes:

whether each service cell grouping in all service cell groupings skips PDCCH monitoring or not;

or,

whether each cell grouping corresponding to the DRX group of the fourth serving cell skips PDCCH monitoring or not.

Specifically, the seventh indication information may further include a bitmap (bitmap) in addition to the seventh duration, where the bitmap indicates whether the serving cell group or the serving cell skips the PDCCH monitoring.

Further, in one case, whether each of all the serving cell groups skips PDCCH monitoring is indicated by bitmap. That is, the PDCCH indicates whether a cropping PDCCH is required for each of all cell groups of the UE.

For example, if the terminal device corresponds to 3 cell groups, a first value in a bitmap for the

cell group

1, 2, 3 indicates that PDCCH monitoring is skipped, a second value indicates that PDCCH monitoring is not skipped, the first value is 1, and the second value is 0, or vice versa; different bits in the bitmap are grouped for different cells; if the bitmap is 101, it may indicate that the PDCCH monitoring is skipped for cell group 1, the PDCCH monitoring is not skipped for all serving cells of cell group 2, and the PDCCH monitoring is skipped for all serving cells of cell group 3.

Furthermore, the seventh indication information may indicate a seventh duration for the same time, that is, the serving cells in one or more cell groups that need to skip PDCCH monitoring all skip PDCCH monitoring with the same seventh duration;

in the still further alternative,

the seventh indication information may include multiple seventh durations, where different seventh durations are used for corresponding to different cell groups that skip PDCCH monitoring. For example, if there are two cell packets skipping PDCCH monitoring, two seventh durations may be indicated, and different cell packets correspond to different seventh durations, and the specific corresponding manner may be one-to-one according to a sequence.

In another case, whether each cell group corresponding to the DRX group in which the fourth serving cell is located skips PDCCH monitoring is determined. That is, the seventh indication information carried by the PDCCH is used to indicate whether each cell grouping in the cell grouping corresponding to the DRX group in which the serving cell is located needs a skiping PDCCH.

For example, the terminal device has 2 DRX packets, the fourth serving cell is the serving cell in DRX packet 2, and the seventh indication information is used to indicate whether each of the one or more serving cells in DRX packet 2 skips PDCCH monitoring.

If the DRX packet 2 corresponds to 4 cell packets, the first value in the bitmap of the

cell packets

1, 2, 3 and 4 indicates that the PDCCH monitoring is skipped, the second value indicates that the PDCCH monitoring is not skipped, the first value is 1, the second value is 0, or vice versa; different bits in the bitmap are grouped for different cells; if the bitmap is 1010, it may indicate that the

cell groups

1, 3 in the DRX group 2 skip PDCCH monitoring, and all serving cells of the cell groups 2, 4 in the DRX group 2 do not skip PDCCH monitoring.

in the alternative to this, either,

the seventh indication information may include a plurality of seventh durations, and different seventh durations are used for corresponding to different cell groups for skipping PDCCH monitoring. For example, if there are two cell packets skipping PDCCH monitoring, two seventh durations may be indicated, and different cell packets correspond to different seventh durations, and the specific corresponding manner may be one-to-one according to a sequence.

And 73, the terminal device determines a serving cell for skipping the PDCCH monitoring and a time range for skipping the PDCCH monitoring according to the seventh indication information.

In this example, the time range for skipping PDCCH monitoring is determined to be the first time unit after the fifth indication information is received, and the duration is the seventh time period.

The above steps 72 to 73 are combined, and the time unit is symbol:

the method for the terminal equipment to receive the PDCCH indication seventh indication information, namely PDCCH blanking information, from any one serving cell in the active time specifically comprises the following steps:

whether each cell needs a cropping PDCCH or not is respectively indicated by using a bitmap method, which may be specifically one of the following:

the PDCCH indicates whether each cell group in the cell groups corresponding to the DRX group where the serving cell is located needs a skiping PDCCH or not;

the PDCCH indicates whether a cropping PDCCH is required for each of all cell groups of the UE.

Then, the terminal device does not monitor the PDCCH (or skips PDCCH monitoring) for a time period, and for the terminal device to start the next symbol after receiving the PDCCH, the terminal device does not monitor the PDCCH on the serving cells corresponding to all cell packets requiring the skiping PDCCH in the following PDCCH skiping duration (the seventh time period).

It should be understood that, if the seventh duration included in the seventh indication information is one, the determined serving cells all use the same seventh duration as the duration for skipping the PDCCH monitoring; and if the plurality of seventh time durations are contained, respectively determining the seventh time durations corresponding to different cell groups according to the cell groups corresponding to different seventh time durations, and skipping PDCC monitoring by adopting different seventh time durations as duration time durations in different cell groups.

Step 74, the terminal device receives eighth indication information sent by a network device corresponding to a primary serving cell PCell within a DRX inactivity time; wherein the eighth indication information includes: the duration of skipping the PDCCH monitoring is the eighth duration.

In this step, if all DRX groups correspond to the same DRX configuration parameters, that is, the active or inactive time is the same, the DRX inactive time may be the inactive time of all cell groups;

or, it may be the inactive time of the cell group in which the primary serving cell is located;

or, the time of inactivity of the DRX packet corresponding to the cell packet in which the primary serving cell is located may be used.

The indication information in step 21 or step 31 may specifically be eighth indication information in this example. In this step, the eighth indication information may be carried by a Wake Up Signal (WUS).

The eighth indication information may further include, in addition to the eighth duration:

whether each cell group corresponding to the DRX group where the primary service cell PCell is located skips PDCCH monitoring or not is determined;

or,

whether each cell group in all cell groups of the terminal equipment skips PDCCH monitoring or not.

That is, the terminal device receives the WUS instruction PDCCH skiping information (eighth instruction information) from the PCell at a DRX inactive time (inactive time), and in addition to the eighth time, the method specifically includes: and respectively indicating whether each cell needs a cropping PDCCH by using a bitmap mode. Specifically, it may be one of the following:

indicating whether each cell grouping in the cell grouping corresponding to the DRX group where the PCell is located needs a skiping PDCCH or not;

indicating whether a cropping PDCCH is required for each of all cell packets of the network device.

Further, in one case, whether each cell group in the cell group corresponding to the DRX group where the PCell is located needs a cropping PDCCH is indicated by a bitmap.

For example, if the DRX group in which the PCell of the terminal device is located is DRX group 1, which corresponds to 3 cell groups, the first value in the bitmap for

cell groups

1, 2, and 3 indicates that PDCCH monitoring is skipped, the second value indicates that PDCCH monitoring is not skipped, the first value is 1, and the second value is 0, or vice versa; different bits in the bitmap are grouped for different cells; if bitmap is 101, it may indicate that cell segment 1 of DRX group 1 skips PDCCH monitoring, all serving cells of cell segment 2 of DRX group 1 do not skip PDCCH monitoring, and all serving cells of cell segment 3 of DRX group 1 skip PDCCH monitoring.

The eighth indication information may indicate an eighth time length for the same time length, that is, the serving cells in one or more cell groups that need to skip the PDCCH monitoring all skip the PDCCH monitoring with the same eighth time length;

in the still further alternative,

the eighth indication information may include a plurality of eighth durations, and different eighth durations are used for corresponding to different cell groups for skipping PDCCH monitoring. For example, if there are two cell packets skipping PDCCH monitoring, two eighth durations may be indicated, and different cell packets correspond to different eighth durations, and the specific corresponding manner may be one-to-one according to a sequence.

In yet another case, it is indicated whether each of all cell packets of the network device requires a skiping PDCCH.

For example, if the terminal device corresponds to 4 cell groups, the first value in bitmap of

cell group

1, 2, 3, 4 indicates that PDCCH monitoring is skipped, the second value indicates that PDCCH monitoring is not skipped, the first value is 1, the second value is 0, or vice versa; different bits in the bitmap are grouped for different cells; if the bitmap is 1010, it may indicate that the PDCCH monitoring is skipped for

cell groups

1 and 3, and the PDCCH monitoring is not skipped for all serving cells of cell groups 2 and 4.

in the still further alternative,

The eighth indication information may include a specific time length of the eighth time length. Still alternatively, the eighth indication information may only include information related to one or more eighth time periods. The specific description is the same as the previous example and is not repeated.

And step 75, the terminal device determines, according to the eighth indication information, to skip the serving cell monitored by the PDCCH and to skip the time range monitored by the PDCCH.

Specifically, the terminal device determines to skip the serving cell monitored by the PDCCH according to the bitmap of the eighth indication information.

Determining a time range for skipping PDCCH monitoring, including one of:

the starting time of skipping the PDCCH monitoring is the next time unit of receiving the eighth indication information, and the duration of skipping the PDCCH monitoring is eighth duration; namely, the PDCCH puncturing duration, that is, the eighth duration that the UE does not monitor the PDCCH, the terminal device does not monitor the PDCCH on the serving cells corresponding to all the cell packets that need the puncturing PDCCH within the subsequent PDCCH puncturing duration from the next symbol that completes the PDCCH reception.

Or,

the starting time of skipping PDCCH monitoring is the time when the next DRX duration timer is started, and the duration of skipping PDCCH monitoring is the eighth duration.

In addition, if the eighth indication information only contains one eighth duration, the terminal device adopts the same eighth duration as the duration for skipping the PDCCH monitoring in the serving cell group which determines not to perform the PDCCH monitoring; and if the eighth indication information contains a plurality of eighth durations, the terminal device takes different eighth durations as the durations for skipping the PDCCH monitoring, which correspond to different serving cell groups, in the serving cell group which is determined not to perform the PDCCH monitoring.

In one example, in a CA scenario, for a UE configured with one or more DRX groups, serving cells corresponding to each DRX group are grouped. The network can instruct the UE to perform PDCCH cropping in one or more cell groups by sending a PDCCH on any one serving cell, wherein the PDCCH cropping duration corresponding to at least one cell group requiring PDCCH cropping is the same.

With reference to fig. 13, the scheme of this example is exemplarily described, assuming that the terminal device has two cell groups, which are

cell groups

1 and 2, respectively, where cell group 1 includes one PCell and one SCell1, and cell group 2 includes scells 2 and 3; in one DRX Cycle (Cycle), the terminal device receives, within a DRX activation time, seventh indication information-1 carried by a PDCCH and sent by (the network device of) Scell1 of the cell group 1, where it is indicated that the PDCCH skipping is performed only in the cell group 1, and a seventh duration-1, the terminal device determines that the PDCCH skipping is performed for all serving cells of the cell group 1, and determines that a time range for skipping the PDCCH monitoring is: starting at the next Symbol of the seventh indication-1, the duration is the seventh duration-1. In the DRX activation time of another cell group 2, the terminal device receives seventh indication information-2 sent by (the network device of) SCell 3 in the cell group 2, where it is indicated that the PDCCH skipping is performed only in the

cell groups

1 and 2, and a seventh duration-1, then the terminal device determines that PDCCH skipping is performed for all serving cells of the

cell groups

1 and 2, and determines that the time range for skipping PDCCH monitoring is: beginning at the next Symbol of the seventh indication-2, the duration is the seventh duration-2.

The terminal device receives eighth indication information carried by the WUS from (a network device of) a primary serving cell PCell within a DRX inactivity time, where an eighth duration is indicated, and then the terminal device determines that PDCCH skipping is performed for all serving cells corresponding to a cell packet in which the primary serving cell is located, and determines that a time range for skipping PDCCH monitoring is: and at the moment when the next DRX duration timer starts after the eighth indication information, the duration is an eighth duration.

Therefore, by adopting the scheme, the processing scheme that the terminal equipment can determine that the PDCCH monitoring is skipped for part of time in part of the cells in all the serving cells according to the indication information in the CA scene is provided, so that the processing mode of skipping the PDCCH monitoring is definitely provided in the processing of the CA scene, unnecessary PDCCH blind detection in the CA scene can be further reduced, and the energy consumption of the terminal is further saved.
