[0001] The present invention relates to the technical field of communications, and particularly to a method for processing a Scell suspension indication, a terminal, and a network device.

Background Art

[0002] With the development of communication technologies, in a New Radio (NR) system, a Discontinuous Reception (DRX) mechanism, or what is called CDRX, has been proposed. The CDRX parameters are defined such that all cells belonging to the same carrier aggregation can be set only with the same set of CDRX parameters, or such that all cells belonging to the same carrier aggregation can be set with multiple sets of CDRX parameters. Among them, cells set with the same set of CDRX parameters can be called one CDRX group, or a DRX group. In the case of multiple CDRX groups, if the suspension indication to each secondary cell Scell is uniformly indicated by diverting the previous suspension indication setting, its flexibility will be reduced.

[0019] For the convenience of understanding, some contents related to the embodiments of the present invention will be described below.

[0020] I. DRX basic model The basic mechanism of DRX is to set one DRX cycle for a terminal UE in the Radio Resource Control connected (RRC_CONNECTED) state. The DRX cycle consists of an "On Duration" and an "Opportunity for DRX". During the "On Duration", the UE monitors and receives the Physical downlink control channel (PDCCH) during the active period. During the "Opportunity for DRX" in the idle period, the UE does not receive data on the downlink channel to save power.

[0021] II. Set Parameters Regarding the DRX on-duration timer (drx-onDurationTimer), when the DRX function is set, the corresponding Medium Access Control (MAC) indicates the time in the wake-up state within one DRX cycle by the drx-onDurationTimer. The drx-onDurationTimer calculates the start point according to a specific formula. Once it starts, it operates continuously until timeout without allowing restart in the middle. Regarding the DRX inactivity timer (drx-InactivityTimer), the drx-InactivityTimer indicates the time for which the corresponding MAC has to continuously monitor the PDCCH after receiving a PDCCH that instructs a new transmission. The drx-InactivityTimer is started or restarted at the first symbol after the reception of a PDCCH that instructs a new transmission (uplink UL or downlink DL) ends. When the corresponding MAC receives a DRX command or a Long DRX command MAC CE, the drx-InactivityTimer is stopped. When the drx-InactivityTimer times out, if a short DRX cycle is set for the corresponding MAC, it enters the short DRX cycle (ShortDrx-Cycle); otherwise, it enters the long DRX cycle (longDRX-Cycle). Regarding the long DRX cycle start offset (longDRX-CycleStartOffset), this parameter can simultaneously represent two meanings: longDRX-Cycle and the DRX start offset (drxStartOffset). Note that when the network device also sets the short cycle (ShortDrx-Cycle) parameter, it should be noted that the long cycle must be set to an integer multiple of the short cycle. Regarding shortDRX-Cycle, this parameter represents the time of the short cycle adopted in DRX, with the unit of ms. ms5 indicates that the time of the short cycle is 5 ms. Regarding the short DRX cycle timer (drx-ShortCycleTimer), this parameter indicates whether to enter the long cycle if the PDCCH has not been continuously received within a short cycle for a certain duration. When its value is 2, it indicates that if the decoding of the PDCCH has not been successful for two consecutive durations, the long cycle will be entered. The time corresponding to the drx-ShortCycleTimer is an integer multiple of the short cycle. When the drx-inactivityTimer times out or a DRX Command is received and a short cycle is set for the corresponding MAC, the drx-ShortCycleTimer is started. When the drx-ShortCycleTimer times out, the corresponding MAC enters the long cycle, or when a Long DRX Command is received, the drx-ShortCycleTimer is stopped and the corresponding MAC enters the long cycle.

[0022] III. Role of the wake up signal (WUS) The WUS controls the start of the next one duration. The WUS is based on the PDCCH, that is, the WUS is the PDCCH and exists during DRX off, that is, outside the active time. It can be regarded as a small PDCCH, where small means that the number of CORESETs and search spaces (SS) occupied in the WUS is smaller than that of the normal PDCCH.

[0023] IV. Secondary cell dormancy indication and purpose To reduce the problem of high power consumption caused by the UE frequently monitoring the PDCCH, in some scenarios, such as in the case of CA carrier aggregation, a dormancy-like operation for the Scell and a PDCCH-based Scell dormancy indication field are introduced. When interpreting the dormant state, in this state, depending on the configuration of the network device, the UE either does not monitor the PDCCH, or the period for monitoring the PDCCH becomes very long, e.g., monitoring the PDCCH once every 2560 slots. In this state, the UE may perform channel state information (CSI) measurement and reporting. In this state, the power consumption of the UE is low. When interpreting the non-dormant state (which can also be interpreted as the active state), in this state, depending on the configuration of the network device, the UE monitors the PDCCH relatively frequently, e.g., monitoring the PDCCH for each downlink slot, and the UE may perform CSI measurement and reporting. In this state, the power consumption of the UE is high. The dormancy state does not exist in the Pcell and only exists in the Scell.

[0024] V. Relationship and differences between WUS and Scell dormancy indication The indication of WUS acts on a per cell group (per CG) basis for each UE's serving cell group, and each CG has only one setting related to DRX. The Scell dormancy indication corresponds to further indicating the dormancy operation of each Scell group in one cell group controlled by WUS.

[0025] VI. Related concepts of SS A resource element (RE) is the smallest unit of the new radio (NR) physical layer resource. The frequency domain is a subcarrier, and the time domain is an orthogonal frequency division multiplexing (OFDM) symbol. A resource element group (REG) consists of a radio bearer (RB) in the frequency domain (12 REs) and one OFDM in the time domain. The REG Bundle contains one group of REGs {iL, iL+1, …… iL+L-1}, where L is determined by the upper layer parameter CORESET-REG-bundle-size. A Control Channel Element (CCE) consists of 6 REGs and is the logical resource unit of the PDCCH. A continuous set of n CCEs constitutes the PDCCH (i.e., the aggregation level). The Aggregation Level defines the number of CCEs that constitute the PDCCH. Regarding the concepts of the Control Resource Set (CORESET) and SS The CORESET indicates the available resources for the PDCCH. The frequency domain consists of multiple 6RBs, and the time domain consists of 1 to 3 OFDM symbols. The PDCCH Search Space indicates the search method for the PDCCH. The UE attempts to decode the Downlink Control Information (DCI) in the PDCCH by performing a blind search in the search space SS and provides it corresponding to the CORESET. The CORESET solves the problem of the existence range of the PDCCH, such as the length of the time domain and the range of the frequency domain. However, as can be seen from the RRC signaling, the CORESET configuration does not indicate the specific time domain position (only provides the duration (number of symbols) of the time domain), and the specific time domain position is provided by the monitoring occasion (MO) provided by the Search Space. Such a design makes the flexibility even higher. The CORESET can be set at any frequency domain position (the configuration parameter FrequencyDomainResources IE is a Bitmap of the physical resource block (PRB) numbers of the current BWP). The Search Space solves the problem of the UE's search method. There is a similar concept in LTE, and its purpose is to reduce the complexity of the UE's brand search as much as possible. Different from LTE, for a specific CORESET, NR can set different Search Spaces for the UE, that is, different brand search methods (such as monitoring period, symbol start position of monitoring, etc.) can be set for the UE. Thereby, the complexity of the UE's brand search can be further reduced. The search space has a certain period. One CORESET has multiple SSs, and multiple CORESETs can be set for one UE.

[0026] Referring to FIG. 2, FIG. 2 is a flowchart of a Scell suspension indication processing method provided by an embodiment of the present invention. The method is performed by a terminal Therefore, it is executed , as shown in FIG. 2, step 201 of receiving a first physical downlink control channel PDCCH; step 202 of determining a suspension operation of a secondary cell group (Scell group) based on the first PDCCH, The first PDCCH includes Scell suspension instructions that correspond one-to-one to at least two discontinuous reception groups (DRX groups). Each Scell suspension instruction is used to instruct the suspension operation of a secondary cell group in one of the DRX groups, and the suspension operation includes suspension or non-suspension. According to the Scell suspension instructions included in the first PDCCH, it is determined whether at least some of the secondary cell groups in a plurality of DRX groups enter suspension or non-suspension.

[0027] Optionally, the first PDCCH is used to detect downlink control information (DCI) in a predetermined format scrambled with a power saving radio network temporary identifier (PS-RNTI).

[0028] In an embodiment of the present invention, the above first PDCCH includes one second PDCCH (i.e., one PDCCH), and may include at least two second PDCCHs (i.e., at least two PDCCHs). When the first PDCCH includes one second PDCCH, the second PDCCH includes at least two Scell suspension instructions. When the first PDCCH includes at least two PDCCHs, each PDCCH includes one Scell suspension instruction respectively.

[0029] In other words, in an embodiment of the present invention, the above first PDCCH includes any of the following cases. Case 1 is that the first PDCCH includes a second PDCCH corresponding one-to-one to the DRX group (that is, each second PDCCH corresponds to one DRX group), the Scell suspension indication included in the second PDCCH is used to indicate the suspension operation of the first Scell group, and the first Scell group is the Scell group in the DRX group corresponding to the second PDCCH. The second PDCCH is the PDCCH of the special cell SPcell. The second PDCCH may be regarded as a PS-PDCCH, and the SPcell may be a primary cell Pcell or a primary secondary cell PScell. Case 2 is that the first PDCCH is one second PDCCH, and the second PDCCH includes at least two of the Scell suspension indications and a wake-up indication corresponding one-to-one to the Scell suspension indication. Case 3 is that the first PDCCH is one second PDCCH, and the second PDCCH includes at least two of the Scell suspension indications and one wake-up indication.

[0030] The fact that the Scell suspension indication is used to indicate the suspension operation of the Scell group in one DRX group may be understood as that in the PDCCH, the Scell is instructed to perform the Scell suspension indication in units of secondary cell groups. The above-mentioned predetermined format refers to format 2_6 or other formats. Taking the case where the predetermined format is format 2_6 as an example, the first PDCCH may be understood as the PDCCH for detecting DCI format 2_6 scrambled with PS-RNTI. Specifically, the network device may provide a plurality of search space sets for the DCI format 2_6 to the terminal, and the terminal may detect the PDCCH based on the search space set to realize the detection of the DCI format 2_6 in the activated downlink BWP of the special cell SpCell.

[0031] Optionally, in this embodiment, the Scells may be grouped by a DRX group, and the Scells in each group may be further subdivided into different Scell groups. Each DRX group corresponds one-to-one with a Scell suspension instruction, and the Scell suspension instruction is used to instruct the suspension operation of the Scell group in the DRX group. It should be understood that in the following embodiments, the suspension operation of the Scell group in the DRX group may be understood as the suspension operation of the activated Scell group in the DRX group.

[0032] It should be noted that the Scell groups may be grouped in various ways, for example, according to frequency bands, frequency ranges, or the capabilities of the UE's high-frequency receivers. The value X of the Scell suspension instruction in the second PDCCH of each DRX group may be 0 bits or more and 5 bits or less, that is, 0 ≤ X ≤ 5. The RRC sets the m-bit Scell suspension instruction for each DRX group in the UE, and different DRX groups are set independently with different m values.

[0033] In the embodiment of the present invention, by including a Scell suspension instruction corresponding one-to-one with the DRX group in the first PDCCH, the setting of the suspension operation of the Scell group in the DRX group is realized. In this way, different Scell suspension instructions can be set by the DRX group, the flexibility of the Scell suspension instruction is improved, and the power consumption of the terminal is further reduced.

[0034] Optionally, for the above Case 1, it may be understood that the Scell suspension indication in the first second PDCCH is used to indicate the suspension operation of the Scell group in the first DRX group, and the Scell suspension indication in the second second PDCCH is used to indicate the suspension operation of the Scell group in the second DRX group. The first DRX group and the second DRX group differ in that at least one of the DRX configuration parameters is different. The DRX configuration parameters include a DRX inactivity timer drx-InactivityTimer, a DRX on-duration timer drx-onDurationTimer, and the like.

[0035] Both second PDCCHs may be located in the SPCell, or the second PDCCH may be located in the SCell in the corresponding DRX group. As shown in FIG. 3, in one embodiment, the second PDCCH is the PDCCH of the SPcell. As shown in FIG. 4, in another embodiment, the second PDCCH is the PDCCH of the target cell in the DRX group corresponding to the second PDCCH. When the DRX group corresponding to the second PDCCH includes the SPcell, the target cell is the SPcell. When the DRX group corresponding to the second PDCCH does not include the SPcell, the target cell is one SCell in the corresponding DRX group. It should be understood that each DRX group may include one or more Scell groups, and each Scell group may include one or more Scells.

[0036] Taking two second PDCCHs as an example, as shown in FIGS. 3 and 4, the two second PDCCHs are PDCCH1 and PDCCH2 respectively. Among them, PDCCH1 corresponds to DRX group1, and DRX group1 corresponds to frequency range 1. PDCCH2 corresponds to DRX group2, and DRX group2 corresponds to frequency range 2. DRX group1 includes two Scell groups (i.e., Scell group1 and Scell group2), each Scell group includes one Scell. DRX group2 includes one Scell group (i.e., Scell group1), and the Scell group includes three Scells. At this time, the Scell suspension indication included in the PDCCH1 may include 2 bits, and the Scell suspension indication included in the PDCCH2 may include 1 bit.

[0037] For the above case 2, only one second PDCCH is set for the SPCell, and the number of bits of the wake-up indication of the energy-saving signal is set according to a plurality of DRX groups. For example, in the case of two DRX groups, a 2-bit wake-up indication is set. As shown in FIG. 5, in order for the terminal and the network device to obtain the same understanding, the same Scell group bits may be set for different DRX groups (that is, the number of bits occupied by each Scell suspension indication is the same).

[0038] It should be understood that for different settings of the first PDCCH, the corresponding terminal should realize the suspension operation when the corresponding second PDCCH is not detected, or the suspension operation when there is no monitoring opportunity. This will be described in detail below.

[0039] In Solution 1, for the above Case 1 and Case 2, a search space set for the terminal to monitor the second PDCCH is configured. When the terminal has not detected the second PDCCH, the sleep operation (sleep or non-sleep) of the secondary cell group in the DRX group corresponding to the undetected second PDCCH satisfies any one of the following. In Solution 1.1, when the RRC configuration includes a target indication, it is determined according to the target indication, and the target indication is used to indicate the sleep operation of the secondary cell group in the DRX group corresponding to each second PDCCH (in other words, in this embodiment, the target indication is used to indicate the sleep operation when the terminal has not detected the second PDCCH). In Solution 1.1, when the number of undetected second PDCCHs is N1, the N1 second PDCCHs are determined by the target indication. In Solution 1.2, when the RRC configuration does not include the target indication, it is determined based on the default sleep operation. In Solution 1.2, when the number of undetected second PDCCHs is N, the N second PDCCHs are determined by the default sleep operation defined by the protocol. In Solution 1.3, it coincides with the most recent sleep operation. In Solution 1.3, the sleep operation for the second Scell group (a specific Scell group in the DRX group corresponding to the second PDCCH) coincides with the most recent sleep operation of the second Scell group. For example, if the second Scell group was most recently in a non-sleep state, the terminal maintains the non-sleep state when it has not detected the second PDCCH. If the second Scell group was most recently in a sleep state, the terminal maintains the sleep state when it has not detected the second PDCCH.

[0040] In an embodiment of the present invention, the above target instruction may be understood as instructing a pause operation in units of Scell groups. That is, a search space set for monitoring a specific second PDCCH is set, and when the terminal has not detected the second PDCCH, for the Scell group in the DRX group corresponding to the second PDCCH, pause control can be performed according to the pause operation correspondingly indicated for the Scell group in the DRX group in the target instruction. When the pause operation instructs that a specific Scell group in the DRX group pauses (or enters a pause state), the Scell group enters a pause state; when the pause operation instructs that a specific Scell group in the DRX group does not pause (or enters a non-pause state), the Scell group enters a non-pause state. In an embodiment of the present invention, in order to respectively instruct the pause operations of each DRX group according to the number of DRX groups, the flexibility of the pause operation instruction for the Scell group in the DRX group is improved.

[0041] That the pause operation of the second Scell group coincides with the most recent pause operation of the second Scell group may be understood as that the current pause operation of the second Scell group coincides with the previous pause operation. If the previous pause operation was in a pause state, then this time it enters a pause state; if the previous pause operation was in a non-pause state, then this time it enters a non-pause state.

[0042] Optionally, that the pause operation of the second Scell group coincides with the most recent pause operation of the second Scell group may be set by a network device or may be defined by a protocol, and is not further limited herein.

[0043] Regarding the above solution 1.1, in one embodiment, the RRC parameter ps-WakeupOrNot (a RRC parameter that the UE has not detected whether the WUS has started the onduration_timer) and the rules regarding this parameter (for example, the scell states corresponding to ps-WakeupOrNot = 0 and 1 are the dormant state and the non-dormant state respectively) may be used to determine the state of the scell. RRC determines whether to start the ondurationtimer of the relevant DRX in the DRX group controlled by the undetected second PDCCH, and sets its Scell dormancy operation. For example, it is set independently in bitmap form. (The undetected PS-PDCCH may be 0 or 1.) For example, if there are two DRX groups, RRC sets the operation of the PS-PDCCH with detection leakage in DRX group 1 not to start its timer, and sets the operation of the PS-PDCCH with detection leakage in DRX group 2 to start its timer.

[0044] When RRC is set to start its timer in the DRX group controlled by a specific undetected second PDCCH, that is, in the case of "1", except for the SPcell, its Scell group enters the non-dormancy state. When RRC is set not to start its timer in the DRX group controlled by a specific undetected second PDCCH, or when the timer is not started by default because RRC has not made a setting, that is, in the case of "0", its Scell group enters the dormancy state.

[0045] In another embodiment, RRC may display a default dormancy operation instruction. In other words, RRC sets the operation of the scell at this time. That is, RRC sets whether the Scell controlled by the undetected second PDCCH enters the dormancy state or the non-dormancy state.

[0046] Regarding the above solution means 1.2, when the RRC does not set the UE operations related thereto, the default operation may be construed as being in the dormancy or non-dormancy state.

[0047] Regarding the above solution means 1.3, the Scell controlled by the undetected second PDCCH may be construed as maintaining its most recent or latest state, e.g., the dormancy or non-dormancy state.

[0048] In solution means 2, regarding the above Case 1 and Case 2, a search space set for monitoring the second PDCCH is set for the terminal, and when there is no monitoring opportunity for the cell set by the second PDCCH, the secondary cell group's suspension operation in the DRX group corresponding to the N second PDCCHs without a monitoring opportunity satisfies any one of the following. In solution means 2.1, the secondary cell groups in L1 first DRX groups enter the non-suspended state, and the L1 first DRX groups are part or all of the DRX groups corresponding to the N second PDCCHs, where both L1 and N are positive integers. In solution means 2.2, the secondary cell groups in the L1 first DRX groups enter the suspended state. In solution means 2.3, when the RRC configuration includes a target indication, it is determined according to the target indication, and the target indication is used to indicate the secondary cell group's suspension operation in the DRX group corresponding to each of the second PDCCHs. In solution means 2.4, when the RRC configuration does not include the target indication, it is determined based on the default suspension operation. In solution means 2.5, it is consistent with the most recent suspension operation.

[0049] The lack of monitoring opportunities for the N second PDCCH cells may be interpreted as follows: although the MO is set in the network device, there is no effective MO within the range of detecting the N second PDCCHs (e.g., it is covered by the active time or collides with other signal channels). Specifically, it may include any one of the following cases, both of which can be interpreted as having no monitoring opportunities. For all corresponding PDCCH monitoring opportunities outside the active time of the next DRX cycle, there is no need to monitor the PDCCH to detect DCI format 2_6. There is no monitoring opportunity for any PDCCH for detecting DCI format 2_6 outside the active time of the next DRX cycle.

[0050] Regarding the above solution means 2.1 and solution means 2.2, it may be interpreted that all or part of the DRX groups corresponding to the N second PDCCHs (where part refers to all Scell groups of some DRX groups) enter the non-dormancy state, or the Scell group enters the dormancy state. For example, when there is no effective MO for any of the second PDCCHs, the Scell group of the primary DRX group 1 (i.e., the DRX group including the SPcell) may be set to enter the non-dormancy state, and the Scell group of the secondary DRX group 2 (i.e., the DRX group not including the SPcell) may be set to enter the dormancy state.

[0051] Regarding the above solution means 2.3, it may be interpreted that the RRC can indicate the suspension operation, in other words, the RRC sets the operation of the scell at this time. That is, the RRC sets the Scell controlled by the undetected second PDCCH to enter the dormancy state or the non-dormancy state.

[0052] Regarding the above solution 2.4, when the RRC does not set the idle operation, the idle operation of the Scell group in the DRX group corresponding to the N second PDCCHs may be understood as the default operation (for example, dormancy or non-dormancy state) defined by the protocol.

[0053] In solution 3, for the above case 1 and case 3, when a search space set for the terminal to monitor the second PDCCH is set and there is no monitoring opportunity for Scells not set by the second PDCCH, the idle operation of the secondary cell group is the idle operation of the secondary cell group in L2 second DRX groups is determined according to the Scell idle indication in the second PDCCH corresponding to the second DRX group, and the idle operation of the secondary cell group corresponding to L3 third DRX groups is determined according to a predetermined rule, and at least one of the above is satisfied. Both L2 and L3 are positive integers. The L2 second DRX groups are part or all of all the DRX groups corresponding to the second PDCCH, and the L3 third DRX groups are part or all of all the DRX groups corresponding to the second PDCCH.

[0054] In an alternative embodiment, the second DRX group includes the SPcell, and the third DRX group does not include the SPcell.

[0055] As shown in FIG. 6, DRX group 1 and DRX group 2 are included. Among them, the active time of the Scell (the Scell not set by the second PDCCH) in DRX group 2 is the hatched area in the figure. The hatched area may be understood as having no monitoring opportunity for the Scell not set by the second PDCCH. At this time, the idle operation for the Scell may include the following cases. In one embodiment, since there are two independent second PDCCHs in the Pcell that indicates the second PDCCH in the DRX group where the SPcell exists is valid, at this time, all Scells in DRX group 2 may be set according to the dormancy operation in a predetermined rule. All Scells in DRX group 1 still follow the instruction of the second PDCCH. In another embodiment, regardless of whether it is a Scell or a Pcell that indicates that all second PDCCHs are invalid, if there is no valid second PDCCH before the cell, it is necessary to set according to the dormancy operation in a predetermined rule. That is, all or part (here, part refers to all Scell groups of a part of the DRX group) of the Scell groups enter the non-dormancy state, or the Scell groups enter the non-dormancy state. In still another embodiment, follow the instruction of the second PDCCH that indicates that all second PDCCHs are valid.

[0056] The above-mentioned predetermined rule may be interpreted as the rule defined in Solution 2. Specifically, the predetermined rule is that the secondary cell group in some or all of the third DRX groups enters the non-dormant state, that the secondary cell group in some or all of the third DRX groups enters the dormant state, when the RRC configuration includes a target instruction, it is to determine according to the target instruction, and the target instruction is used to indicate the default dormancy operation of the secondary cell group in the third DRX group corresponding to each of the second PDCCHs, when the RRC configuration does not include the target instruction, it is to determine based on the default dormancy operation, and to match the most recent dormancy operation, and includes any one of them.

[0057] Furthermore, in one embodiment, the method further includes receiving upper layer signaling transmitted from a network device, and the upper layer signaling includes a power saving offset PS-offset that corresponds one-to-one to the DRX group.

[0058] In an embodiment of the present invention, the PS-offset may be a setting for each DRX group, which means setting different PS-offsets according to the DRX group. The PS-offset is used to instruct the UE to start monitoring the second PDCCH based on the SS.

[0059] It should be noted that in an embodiment of the present invention, the first PDCCH further includes a wake-up indication, which is an energy saving signal indication for instructing the start or stop state of the DRX on-duration timer drx-ondurationtimer.

[0060] It should be understood that in an embodiment of the present invention, the above energy saving signal indication can be used to instruct the state of the drx-ondurationtimer corresponding to one or more DRX groups. In an alternative embodiment, when each energy saving signal indication is used to instruct the state of the drx-ondurationtimer corresponding to one DRX group, the energy saving signal indication and the pause indication in the second PDCCH correspond one-to-one.

[0061] When the DRX on-duration timer indicated by the energy saving signal indication corresponding to the fourth DRX group is stopped, the Scell group in the fourth DRX group enters a pause state, and the fourth DRX group is any DRX group.

[0062] In other words, in the embodiments of the present invention, if the PS-PDCCH is instructed not to start the ondurationtimer, the Scell dormancy indication of the related DRX group needs to indicate whether the Scell group enters or maintains the dormancy state. When the ondurationtimer is started, the Scell state may be determined according to the cases defined in the above solution means 1 to solution means 3.

[0063] To better understand the specific implementation of the present invention, the following will be described in more detail with different embodiments. Embodiment 1

[0064] As shown in FIG. 3, one PS-PDCCH (full name: PDCCH for detecting DCI format 2_6 scrambled with PS-RNTI) is set for each DRX group, that is, before each DRX ON, there are at least two PS-PDCCH monitoring occasions (PS-PDCCH MO) for instructing different DRX groups respectively, and they are all set on the PCell or the PScell (in the DC scenario, multiple Cell groups are set for the UE, and each Cell group has one Pcell or PScell, collectively referred to as Spcell).

[0065] Optionally, the Scell dormancy indication groups the Scells by DRX group, further subdivides the Scells of each group as different Scell groups, and independently indicates the dormancy operations of the Scell groups in each DRX group with two different PS-PDCCHs. The Scell groups may be grouped in various ways, for example, according to frequency bands, frequency ranges, the capabilities of the UE's high-frequency receivers, etc. The value X of the Scell dormancy indication in the PS-PDCCH of each DRX group may be 0 bits or more and 5 bits or less, that is, 0 ≤ X ≤ 5. The RRC sets the m-bit Scell suspension indication in each DRX group for the UE, and independently sets different m values for different DRX groups. Such a design of setting the PS-PDCCH by DRX group is more flexible.

[0066] Regarding the detection of PS-PDCCH, In Case 1, the MO is set, but the UE is not detecting the PS-PDCCH. If a search space set (SS set) for monitoring the PS-PDCCH in the PCell or PSCell is provided to the UE and the UE does not detect DCI format 2_6, the operation of the Scell includes one of the following options. In Option 1, based on the RRC parameter ps-WakeupOrNot (an RRC parameter that the UE does not detect whether WUS starts the onduration_timer) and the rules regarding this parameter (for example, the content of the scell state corresponding to ps-WakeupOrNot = 0, 1), the state of the scell may be determined. RRC determines whether to start the ondurationtimer of the related DRX in the DRX group controlled by the undetected PS-PDCCH, and sets the Scell suspension operation. For example, it is set independently in bitmap format. (The undetected PS-PDCCH may be 0, 1) For example, if there are two DRX groups, RRC sets the operation of the PS-PDCCH with detection leakage in DRX group 1 not to start its timer, and sets the operation of the PS-PDCCH with detection leakage in DRX group 2 to start its timer. When RRC is set to start its timer in the DRX group controlled by a specific undetected PS-PDCCH, that is, in the case of "1", except for the Pcell, its Scell group enters the dormancy state or its Scell group enters the non-dormancy state. When RRC is set not to start its timer in the DRX group controlled by a specific undetected PS-PDCCH, or when the timer is not started by default because RRC has not made a setting, that is, in the case of "0", its Scell group needs to enter the dormancy state. In Option 2, an indication is displayed and RRC sets the operation of the Scell at this time. That is, RRC sets whether the Scell controlled by the undetected PS-PDCCH enters the dormancy state or the non-dormancy state. If RRC does not set it, the default operation is the dormancy or non-dormancy state. In Option 3, maintain the current state without indication (No indication and keep the current state). The Scell controlled by an undetected PS-PDCCH maintains its most recent or latest state, e.g., the dormancy or non-dormancy state.

[0067] In Case 2 (no effective MO for the Pcell), if the MO is set but there is no effective MO within the range where the PS-PDCCH is detected (e.g., covered by the active time or collided with other signal channels), start the ondurationtimer of the DRX group, and the operation of the Scell includes one of the following options. In Option 4, all or some (where some refers to all Scell groups of some DRX groups) of the related Scell groups of the DRX group enter the non-dormancy state, or the Scell group enters the dormancy state. For example, if there is no effective MO for any of the PS-PDCCHs, the Scell group of the primary DRX group 1 (i.e., the DRX group including the Pcell) may be set to enter the non-dormancy state, and the Scell group of the secondary DRX group 2 (i.e., the DRX group not including the Pcell) may be set to enter the dormancy state. In Option 5, display an indication and the RRC configures the operation of the Scell at this time. That is, the RRC configures whether the Scell controlled by the undetected PS-PDCCH enters the dormancy state or the non-dormancy state. If the RRC does not configure, the default operation is the dormancy or non-dormancy state. In Option 6, maintain the current state without indication (No indication and keep the current state). The Scell controlled by an undetected PS-PDCCH maintains its most recent or latest state, e.g., the dormancy or non-dormancy state.

[0068] In Case 3, as shown in FIG. 6, a search space set for monitoring the PS-PDCCH is configured for the terminal, and when there is no monitoring opportunity for Scells not configured with the PS-PDCCH, the operation of the Scells includes one of the following options. In Option 7, since there are two independent PS-PDCCHs in the Pcell (where the PS-PDCCH of the DRX group with the Pcell indicates being active), at this time, all Scells of DRX group 2 may be configured according to the dormancy operation in a predetermined rule. All Scells of DRX group 1 still follow the indication of the PS-PDCCH. In Option 8, regardless of whether it is a Scell or a Pcell (where all PS-PDCCHs indicate being inactive), if there is no valid PS-PDCCH before the cell, all need to be configured according to the dormancy operation of a predetermined rule. That is, all or some (where some here refers to all Scell groups of some DRX groups) of the Scell groups enter the non-dormancy state, or the Scell groups enter the non-dormancy state. In Option 9, follow the indication of the PS-PDCCH (where all PS-PDCCHs indicate being active).

[0069] Optionally, the PS-offset may be a per DRX group setting, which means setting different PS-offsets according to the DRX group.

[0070] Optionally, in the above cases, if the PS-PDCCH is instructed not to start the ondurationtimer, the Scell dormancy indication of the related DRX group needs to indicate whether the Scell group enters or maintains the dormancy state. When the ondurationtimer is started, the Scell state is configurable and may also be determined by the above cases. Embodiment 2

[0071] As shown in FIG. 4, one PS-PDCCH is set for each DRX group, but they are set in different cells. One Scell is selected as the PS-PDCCH Scell, and a PS-PDCCH is set to indicate one DRX group in this Scell.

[0072] The Scell dormancy indication is consistent with that in Embodiment 1, and the description thereof is omitted here.

[0073] For the detection of the PS-PDCCH, for the Pcell or the PS-PDCCH Scell, since the PS-PDCCH before its DRX ON only independently controls the Scell dormancy operation corresponding to its DRX group, there is no case 3 in this part, and only case 1 and case 2 exist, which is different from Solution 1 only in this point (case 1 and case 2 are slightly different from Solution 1 and need to be changed in the case of one PS-PDCCH). Embodiment 3

[0074] As shown in FIG. 5, only one PS-PDCCH is set in the Pcell, and the number of Wake-up indication bits is increased according to a plurality of DRX groups. For example, in the case of two DRX groups, a 2-bit wake-up indication is set.

[0075] Regarding the detection of the PS-PDCCH, in this embodiment, only the case of case 3 (the case considering only one PS-PDCCH) exists. Embodiment 4

[0076] As shown in FIG. 7, only one PS-PDCCH is set in the Pcell, and only one Wake-up indication bit is used, that is, a plurality of DRX groups are all indicated by one wake-up indication bit.
