Description

Auxiliary WUS parameter configuration method and device, storage medium, service base station and terminal

Technical Field

The invention relates to the technical field of communication, in particular to a method and a device for configuring auxiliary WUS parameters, a storage medium, a service base station and a terminal.

Background

In the prior art, a base station (i.e., a serving base station) directly indicates, to a UE (User Equipment) in a connected state, a serving Cell to which Secondary Discontinuous Reception (Secondary DRX) configuration is applicable, for example, indicating that part of serving cells, such as SCell 2, SCell3, and SCell4, in a Secondary Cell (Secondary Cell, SCell) adopt Secondary DRX configuration, and other serving cells, such as Primary Cell (Primary Cell, PCell), and SCell1 adopt Primary DRX (Primary DRX) configuration. Here, taking a UE configured with 5 serving cells as an example, a PCell (primary cell) and scells 1-scells 4 are both serving cells configured by the UE.

For UE configured with DRX, the UE periodically wakes up to monitor downlink control signaling DCI sent by a service base station in the On Duration. The Cycle is determined by the DRX Cycle. In practice, the UE does not receive the scheduling information of the serving base station every time the On Duration wakes up to monitor the DCI, because there is no Downlink data transmission On the serving base station side, the UE wakes up to monitor nothing, but power consumption of the UE increases, in order to cope with such a scenario and achieve a better power saving effect, a Wake Up Signal (WUS) is introduced, the WUS is configured in a time window before the On Duration, and a PS-RNTI scrambled DCI transmission is adopted, if the DCI indicates that the UE needs to Wake up, the UE wakes up to monitor a PDCCH (Physical Downlink Control Channel) transmitted by the serving base station at the subsequent On Duration; if the DCI indicates that the UE does not need to wake up, the UE continues to sleep at the subsequent On Duration without detecting the PDCCH. Fig. 1 is an example, when the UE detects a WUS at a non-Active Time (non-Active Time) of DRX Cycle m, but the WUS indicates that the UE does not need to wake up, the UE does not need to wake up to detect a PDCCH at the On Duration of DRX Cycle m +1 (i.e., the next On Duration relative to receiving the WUS).

In the latest 3GPP discussion, in order to improve the power saving effect, a Secondary DRX configuration, referred to herein as Secondary DRX configuration, is to be introduced. The DRX configuration applied on the PCell is referred to as Primary DRX configuration.

However, when the UE configures the secondary DRX configuration, whether the UE can be used in conjunction with the WUS and how to apply the WUS to the secondary DRX configuration are problems to be solved.

Detailed Description

In a wireless communication system, such as LTE or New Radio (NR), in order to enable a UE to be temporarily inactive when there is no traffic in order to reduce power consumption, a serving base station may configure DRX for the UE in a connected state.

Specifically, when DRX is configured, the UE does not need to continuously monitor a Physical Downlink Control Channel (PDCCH). Wherein, DRX has the following characteristics:

activation Duration (On Duration): the UE waits for the duration of receiving the PDCCH after waking up every DRX cycle. If the UE successfully decodes the PDCCH of the UE, the UE keeps waking up and activates an inactive timer;

-inactivity timer: the UE waits for the duration of successfully decoding its PDCCH from the last successfully decoding its PDCCH, and if it fails, it may return to the sleep state. The UE restarts the inactivity timer only after a single successful decoding of its PDCCH, only for the first transmission (i.e., not for retransmission);

-a retransmission timer: a duration until retransmission is possible;

-a period: a periodic repetition of a specified duration, followed by a possible inactivity duration;

active Time duration (Active Time): the UE monitors the total duration of the PDCCH. This includes the "on duration" of the DRX cycle, the time the UE is performing continuous reception when the inactivity timer has not expired, and the time the UE is performing continuous reception while waiting for a retransmission opportunity.

For a UE configured with DRX, the UE does not need to continuously detect PDCCH. The UE only needs to wake up to detect the PDCCH at the start time of each DRX Cycle (Cycle), i.e. during the On Duration (On Duration), specifically, to detect the downlink physical control signaling sent by the serving base station On the PDCCH. The UE identifies whether the physical downlink control signaling is the own physical downlink control signaling according to the Radio Network Temporary Identity (RNTI) of the UE, and the physical downlink control signaling is scrambled by the Temporary identity of the UE. The serving base station configures the Duration of the On Duration, and if the UE receives a Downlink Control Information (DCI) indicating Downlink scheduling or uplink transmission sent by the serving base station during the On Duration, the UE needs to start/restart an inactivity-timer (inactivity-timer) in order to keep the UE in an active state for a certain period of time, since data transmission usually lasts for a certain period of time. When the UE finds that there is no scheduling information of its own, such as a new transmission or a retransmission, and is not during the On Duration, and after a relevant timer, such as an inactivity-timer, expires, the UE may enter a DRX Sleep (Sleep) interval, where the UE does not need to detect the PDCCH.

The network configures parameters such as DRX start offset (DRX-StartOffset) and DRX Cycle, and the UE can calculate the start time of each DRX Cycle On Duration according to the parameters through an expression preset by a protocol.

In order to increase the data transmission rate of the UE, the serving base station may configure Carrier Aggregation (Carrier Aggregation) for the UE, where the UE has multiple serving cells, one of which is a Primary Cell (PCell) and the other is a Secondary Cell (SCell). The UE receives a system message and a paging message on the PCell, and typically, Radio Resource Control (RRC) signaling of the UE is also transmitted only on the PCell. Carrier aggregation of up to 16 serving cells may be supported in NR. For scells, there may be an active state, an inactive state, or a dormant (dormant) state. For the UE, the PCell is always in the active state.

After the UE configures carrier aggregation, the serving base station may configure DRX for the UE at the same time. In the previous protocol release, the UE configuring carrier aggregation has only one common set of DRX parameters, i.e. all active serving cells wake up at the same time or enter the DRX Sleep interval at the same time.

For UE configured with DRX, the UE periodically wakes up to monitor downlink control signaling DCI sent by a service base station in the On Duration. The Cycle is determined by the DRX Cycle. In practice, the UE does not receive the scheduling information of the serving base station every time the On Duration wakes up to monitor the DCI, and there is a case that no downlink data is transmitted On the serving base station side, so the UE wakes up to monitor nothing, but the power consumption of the UE increases.

Referring to fig. 1, fig. 1 is a schematic diagram of a working scenario of a WUS in the prior art.

As shown in fig. 1, the WUS configures a time window before the On Duration, and uses PS-rnti (power Saving rnti) scrambled DCI transmission, if the DCI indicates that the UE needs to wake up, the UE wakes up at the following On Duration to monitor the PDCCH sent by the serving base station; if the DCI indicates that the UE does not need to wake up, the UE continues to sleep at the subsequent On Duration without detecting the PDCCH, i.e., without monitoring the PDCCH. FIG. 1 is an example of a UE detecting a WUS during a DRX Cycle (Cycle) m, but the WUS indicating that the UE does not need to wake up, the UE does not need to wake up to detect a PDCCH during an On Duration of DRX Cycle m + 1. As can be seen from the figure, when the UE receives the WUS DCI, it can know whether the next On Duration, that is, the On Duration immediately after the WUS, needs to wake up to monitor the PDCCH.

However, for the case where the UE configures the secondary DRX configuration, whether to be used in conjunction with the WUS and how to apply the WUS to the secondary DRX configuration are issues to be solved.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Referring to fig. 2, fig. 2 is a flowchart of a method for configuring a secondary WUS parameter according to an embodiment of the present invention. The method for configuring the secondary WUS parameters may be used for a serving base station side, and may further include steps S21 to S22:

step S21: configuring auxiliary WUS parameter information for auxiliary DRX;

step S22: sending the auxiliary WUS parameter information to the UE so that the UE determines auxiliary WUS parameters;

wherein the secondary WUS parameter information includes at least a portion of the secondary WUS parameters.

In a specific implementation of step S21, the auxiliary WUS parameter information may be configured based on a request from the UE, or may be actively configured by the serving base station, so that the serving base station has an opportunity to configure the auxiliary WUS parameter for the UE according to information interaction with the UE, thereby better meeting the power saving requirement of the UE.

In a specific application scenario of the embodiment of the present invention, a UE accesses a primary cell, establishes an RRC (Radio Resource Control) connection, and carries out a service, and a serving base station configures carrier aggregation for the UE according to a capability and a service characteristic of the UE, and configures 5 scells, such as SCell1-SCell5, in addition to a PCell. SCell are all active. The serving base station configures DRX for the UE considering that traffic of the UE is intermittent. Wherein the DRX parameter may include: DRX slot offset (DRX-SlotOffset), DRX short cycle (DRX-short cycle), DRX short cycle Timer Duration (DRX-short cycle Timer), DRX long cycle start offset (DRX-long cycle startoffset), DRX inactivity Timer Duration (DRX-inactivity Timer), and DRX activation Duration (DRX-On Duration Timer). The primary DRX is applicable to all serving cells, e.g., can include PCell and SCell1-SCell5, because the serving base station does not explicitly indicate the serving cell to which the primary DRX is applicable.

During this period, the serving base station may configure the WUS for the UE, such as configuring a necessary parameter PS-RNTI for the UE, detecting slot information (which may be an offset value with respect to the immediately On Duration start time) of the WUS, detecting a Control Resource Set (core) of the WUS and a corresponding search space (search space). The UE detects the WUS in the non-activation time of the DRX according to the WUS configuration parameters On the PCell, and if the DCI of the WUS is detected and the UE is indicated to need to detect the PDCCH, the UE wakes up to detect the PDCCH at the next On Duration; if the UE detects the WUS DCI but indicates that it does not need to detect the PDCCH, the UE does not need to wake up at the next On Duration. The DCI indicating the WUS may indicate whether multiple UEs need to wake up at the next On Duration at the same time, and at this time, a bitmap may be used, where each bit (e.g., one bit indicates 1) or several bits (e.g., two consecutive bits 11) indicates whether one UE needs to wake up to detect the PDCCH at the next On Duration, and different UEs correspond to different bits or different bits in the bitmap. If the DCI of the WUS is applied to a plurality of UEs, the serving base station needs to indicate the position in the bitmap corresponding to each UE in advance, so that different UEs can acquire their corresponding Wake up signals. If the WUS DCI is only used for one UE, the serving base station may not indicate the position of the UE in this bitmap in advance, so this bitmap has only 1-bit information.

In one embodiment, after the UE operates for a period of Time, it finds Active Time of DRX all the Time without data transmission in some serving cells, and is power-consuming, so the UE expects the serving base station to configure the secondary DRX configuration for itself.

The UE may indicate a request to configure the secondary DRX configuration to the serving base station through uplink signaling, such as RRC signaling, after receiving the request, the serving base station may configure the secondary DRX configuration for the UE in combination with a data transmission state on different serving cells and frequency point information of different serving cells, because serving cells of adjacent frequency points may be generally served by one radio frequency transceiver RF, and accordingly, the serving base station may configure the secondary DRX configuration for the UE, and the serving base station simultaneously indicates serving cells to which the secondary DRX configuration is applicable, for example, indicates that the secondary DRX configuration is applicable to SCell4 and SCell5, and supposing that frequency points of SCell4 and SCell5 and other serving cells are different from each other, the serving base station prejudges that the UE uses independent RF transceivers to serve SCell4 and SCell 5. After receiving the configuration information sent by the serving base station, the UE acquires the auxiliary DRX configuration and the applicable serving cell, and determines the starting time of the On Duration of the auxiliary DRX On the SCell4 and the SCell5 according to the auxiliary DRX parameter configuration, the configured DRX period, the DRX-longCyclerStartOffset and other parameters. The UE may determine the start time of the On Duration of the secondary DRX by using a method specified in an existing protocol, or may use a newly introduced method, which is not limited in the present invention. The secondary DRX configuration may contain all or part of the parameters of the primary DRX configuration, or the serving base station configures only part of the parameters of the secondary DRX, and the rest of the unconfigured parameters use the same name parameters in the primary DRX configuration. At this time, the UE applies primary DRX configuration on PCell and SCell1-SCell3, and secondary DRX configuration on SCell4 and SCell 5.

Since WUS in the related art is applicable only to the primary DRX configuration and to the serving cell PCell and SCell1-SCell3 to which the primary DRX configuration is applied, the UE detects WUS on the PCell, and thus for the secondary DRX configuration, it is necessary to configure a secondary WUS associated therewith.

Specifically, the secondary WUS parameters may include: the method comprises the steps of PS-RNTI corresponding to the auxiliary WUS DCI, time slot information for detecting the auxiliary WUS DCI, CORESET for detecting the auxiliary WUS DCI, a search space located in the CORESET, bit information applicable to the auxiliary WUS in the WUS DCI, cell indication information for determining a serving cell applicable to the auxiliary WUS, and application information for indicating whether the main WUS is applicable to a main DRX serving cell and the auxiliary DRX serving cell.

It is noted that the secondary WUS parameters may include some or all of the above 7 parameters, and may also include other suitable parameters, as the case may be, and thus the specific secondary WUS parameters may not be 7, but may be in other numbers. The auxiliary WUS parameter information may be all or a part of the auxiliary WUS parameters. For example, the auxiliary WUS parameters include 7 parameters, 5 of the parameters are sent to the UE by using the auxiliary WUS parameter information, and for the other 2 parameters, the UE may directly use a preset value, may also directly use a parameter value predefined in a protocol, and may also use a parameter value of the main WUS parameter, which is not limited in this embodiment of the present invention.

Because different bearers of the UE can be mapped to different serving cells, for example, the serving base station can configure logical channels corresponding to some bearers to be transmitted only On PCell and SCell1-SCell3 through RRC signaling, configure logical channels corresponding to other bearers to be transmitted only On SCell4 and SCell5, and different bearers carry different traffic characteristics, a set of WUS configurations, such as WUS On PCell, can only reflect scheduling requirements On PCell and SCell1-SCell3, and scheduling requirements of bearers, such as mapped to PCell and SCell1-SCell3, are not related to SCell4 and SCell5, and at this time, the set of WUS is not suitable for controlling On Duration of the second set of DRX On SCell4 and SCell 5.

In a first specific embodiment of step S22, the auxiliary WUS parameter information may include at least slot information for detecting the auxiliary WUS, and the serving base station may send the slot information for detecting the auxiliary WUS DCI to the UE, so that the UE detects the auxiliary WUS DCI according to the slot information for detecting the auxiliary WUS DCI, then parses bit information indicating a detection PDCCH in the auxiliary WUS DCI, and determines whether monitoring of the PDCCH at a next On Duration of the auxiliary DRX is required.

It can be understood that, in addition to detecting the slot information of the auxiliary WUS, the UE may use a preset value, may directly use a parameter value predefined in the protocol, may use a parameter value of the main WUS parameter, and preferentially uses the parameter value of the main WUS parameter for the UE.

Wherein different WUS detection slot information is used to indicate different offset values relative to the On Duration start time of the second set of DRX (i.e., secondary DRX).

It is noted that the UE still detects WUS on PCell, at which time the UE detects WUS for PCell, SCell1-SCell3 (hereinafter referred to as primary DRX compliant serving cell group) and for SCell4 and SCell5 (hereinafter referred to as secondary DRX compliant serving cell group), respectively, according to the two slot information. If the WUS is detected and the PDCCH detection is indicated to be needed, the PDCCH is detected On the service cells by waking up at the next On Duration according to the service cell group corresponding to the time slot of the WUS, such as the service cell group applicable to the main DRX.

Referring to fig. 3, fig. 3 is a schematic diagram of a working scenario of a WUS in an embodiment of the present invention.

As shown in fig. 3, in the serving cell group for which the main DRX is applicable, the main WUS configures a Time window before the On Duration (i.e., a region), and transmits DCI scrambled by PS-RNTI, and if the DCI indicates that the UE needs to wake up, the UE wakes up at the subsequent On Duration to monitor a PDCCH sent by the serving base station On the serving cell group for which the main DRX is applicable, where the region B is Active Time; if the DCI indicates that the UE does not need to wake up, the UE continues to sleep On the serving cell group applicable to the primary DRX in the following On Duration without detecting the PDCCH, namely without monitoring the PDCCH. FIG. 3 is an example of a case where the UE detects a master WUS in DRX Cycle m, but the master WUS indicates that the UE does not need to wake up, and the UE does not need to wake up to detect PDCCH On the serving cell group to which the master DRX applies in the On Duration of DRX Cycle m + 1.

Further, by configuring different WUS detection slot information, that is, in the region C, an offset value from the On Duration start time of the secondary DRX or an offset value from the On Duration start time of the primary DRX (the offset value is different from the slot information for detecting the DCI of the primary WUS), it is possible to enable the UE to detect the DCI of the secondary WUS using the slot information for detecting the secondary WUS to determine whether to monitor the PDCCH at the next On Duration On the serving cell to which the secondary WUS is applicable, in the serving cell to which the secondary DRX is applicable. In this embodiment, the UE still detects the WUS on the host cell, and the UE knows the DRX applicable to the detected WUS through different WUS detection slots.

With continued reference to fig. 2, in the first specific implementation manner of step S22, by configuring the auxiliary WUS parameter information to enable the UE to determine the auxiliary WUS parameters, the serving base station may configure slot information for detecting the auxiliary WUS for the UE according to information interaction with the UE, so that after the UE configures the auxiliary WUS parameter information, the UE determines whether to need to monitor the PDCCH at the next On Duration of the auxiliary DRX.

In a second specific embodiment of step S22, the auxiliary WUS parameter information at least includes bit information applicable by the auxiliary WUS in the WUS DCI, and the serving base station may send the bit information applicable by the auxiliary WUS in the WUS DCI to the UE, so that the UE detects the WUS DCI according to the slot information for detecting the main WUS, parses the bit information indicating the detection PDCCH in the WUS DCI, and then determines whether to monitor the PDCCH at the next On Duration of the auxiliary DRX On the serving cell indicated by the serving cell group applicable by the auxiliary DRX according to the bit information applicable by the auxiliary WUS in the WUS DCI. With the second embodiment, there is only one WUS, also named host WUS.

It can be understood that, in addition to other auxiliary WUS parameter information applicable by the auxiliary WUS in the WUS DCI, the UE may use a preset value, may directly use a parameter value predefined in the protocol, and may also use a parameter value of the main WUS parameter.

Specifically, with the current WUS configuration parameters, the serving base station indicates, through RRC signaling, bit information (which may be one bit information or multiple bit information in one bitmap) applicable to the serving cell group to which the first DRX applies in the WUS DCI, and indicates bit information applicable to the serving cell group to which the second DRX applies in the WUS DCI at the same time. This is an embodiment of bitmap as shown in table 1.

TABLE 1

Bit position	1	2	3	4	5	6	7	8	9	10
											Bit value	1	0	0	1	0	1	1	0	0	1

As shown in table 1, bit information indicating whether monitoring of the PDCCH is required in the WUS DCI includes 10 bits, the serving base station indicates to the UE that a bit corresponding to the serving cell group to which the main DRX is applicable is a 4 th bit of the 10 bits, and indicates to the UE that a bit corresponding to the serving cell group to which the second DRX is applicable is a 5 th bit of the 10 bits.

After receiving the information, the UE detects a DCI of the WUS according to the slot information (which may be one slot or multiple slots) where the WUS is located, after detecting the DCI, analyzes the bit information of the detected PDCCH therein to obtain 10-bit information, the UE reads a 4 th bit, such as 1 (monitoring PDCCH), and detects the PDCCH On the serving cell group to which the first DRX is applicable at an immediately subsequent On Duration, which is determined according to the first DRX configuration; the UE reads the 5 th bit, e.g. 0 (not monitoring PDCCH), and the UE does not need to monitor PDCCH in the serving cell set applicable to the second DRX at the next On Duration, which is determined according to the second DRX configuration.

In the embodiment of the invention, the UE determines the auxiliary WUS parameters by configuring the auxiliary WUS parameter information, so that the service base station can configure bit information applicable to the auxiliary WUS in the DCI for the UE according to information interaction between the service base station and the UE, and the UE determines whether the PDCCH needs to be monitored in the next On Duration of the auxiliary DRX after the UE configures the auxiliary WUS parameter information. In addition, the method realizes the application of the auxiliary WUS only by adding one parameter configuration, so that the signaling overhead can be obviously saved, and meanwhile, the UE only needs to detect the DCI of the WUS once in one DRX period, so that the power consumption can be further reduced.

It should be noted that, in another embodiment, the auxiliary WUS parameter information may include bit information applicable to a serving cell group to which the main DRX is applicable and bit information applicable to a serving cell group to which the auxiliary DRX is applicable, and the serving base station may send the bit information applicable to the serving cell group to which the main DRX is applicable and the bit information applicable to the serving cell group to which the auxiliary DRX is applicable to the UE, so that the UE detects the WUS DCI according to the slot information for detecting the main WUS, analyzes the bit information indicating the detection PDCCH in the WUS DCI, and then determines whether to monitor the PDCCH at the next On Duration of the auxiliary DRX On the serving cell indicated by the serving cell group to which the auxiliary DRX is applicable according to the bit information applicable to the auxiliary WUS in the WUS DCI.

In a third specific embodiment of step S22, the secondary WUS parameter information may include at least a search space for detecting the secondary WUS DCI, and the serving base station may send the search space for the secondary WUS DCI to the UE, so that the UE detects the secondary WUS DCI in the search space, then parses bit information indicating a detection PDCCH in the secondary WUS DCI, and determines whether monitoring of the PDCCH at a next On Duration of secondary DRX is required.

It is understood that, in addition to detecting other auxiliary WUS parameter information besides the search space of the auxiliary WUS DCI, the UE may use a preset value, may directly use a parameter value predefined in the protocol, and may also use a parameter value of the main WUS parameter.

In implementations, the current WUS configuration may be employed except for a search space where different WUS detections are configured, or CORESET and search space. For example, the search space for WUS detection applicable to the primary DRX serving cell is 1, and the search space for WUS detection applicable to the secondary DRX serving cell group is 2, and the UE detects the DCI for WUS in different search spaces, and determines whether to wake up to monitor the PDCCH in the next On Duration in the corresponding serving cell group applicable to primary or secondary DRX according to the information for monitoring the PDCCH included in the DCI.

In the embodiment of the invention, the UE determines the auxiliary WUS parameters by configuring the auxiliary WUS parameter information, so that the service base station can configure the search space for detecting the DCI of the auxiliary WUS for the UE according to the information interaction between the service base station and the UE, and the UE determines whether the PDCCH needs to be monitored at the next On Duration of the auxiliary DRX after the UE configures the auxiliary WUS parameter information.

It should be noted that, in another specific embodiment, the auxiliary WUS parameter information may at least include a CORESET for detecting DCI of the auxiliary WUS and a search space located in the CORESET, and the serving base station may send the CORESET for detecting DCI of the auxiliary WUS and the search space located in the CORESET to the UE, so that the UE detects DCI of the auxiliary WUS in the search space, then parse bit information indicating to detect a PDCCH in the DCI of the auxiliary WUS, and determine whether to monitor the PDCCH at a next On Duration of the auxiliary DRX, that is, monitor the PDCCH at a serving cell in a serving cell group applicable to the auxiliary DRX.

It is understood that, in addition to detecting the CORESET of the DCI of the secondary WUS and other information of the secondary WUS parameters located outside the search space of the CORESET, the UE may use a preset value, may directly use a parameter value predefined in the protocol, and may also use a parameter value of the primary WUS parameter.

Unlike the previous embodiment that includes detecting the search space of the secondary WUS DCI, the CORESET that detects the secondary WUS DCI may also be different.

In the embodiment of the invention, the UE determines the auxiliary WUS parameters by configuring the auxiliary WUS parameter information, so that the service base station can configure the CORESET for detecting the DCI of the auxiliary WUS and the search space positioned in the CORESET for the UE according to the information interaction between the service base station and the UE, and the UE determines whether the PDCCH needs to be monitored at the next On Duration of the auxiliary DRX after the UE configures the auxiliary WUS parameter information.

In a fourth specific implementation manner of step S22, the auxiliary WUS parameter information may at least include a PS-RNTI corresponding to the auxiliary WUS DCI, and the serving base station may send the PS-RNTI corresponding to the auxiliary WUS DCI to the UE, so that the UE detects the auxiliary WUS DCI according to the RNTI, then parses bit information indicating a detection PDCCH in the auxiliary WUS DCI, and determines whether monitoring of the PDCCH at a next On Duration of the auxiliary DRX is required.

It can be understood that the UE may use a preset value, may directly use a parameter value predefined in the protocol, and may also use a parameter value of the main WUS parameter, except for other auxiliary WUS parameter information corresponding to the auxiliary WUS DCI, such as the PS-RNTI.

In a specific implementation, the current WUS configuration may be employed, except that different PS-RNTIs are configured, e.g., the WUS detected RNTI for the first DRX serving cell is PS-RNTI1, and the WUS detected RNTI for the second DRX serving cell is PS-RNTI 2. The UE detects the WUS DCI scrambled by different RNTIs to know whether the corresponding DRX serving cell needs to wake up to monitor the information of the PDCCH at the next On Duration.

In the embodiment of the invention, the UE determines the auxiliary WUS parameters by configuring the auxiliary WUS parameter information, so that the service base station can configure the PS-RNTI corresponding to the auxiliary WUS DCI for the UE according to information interaction between the service base station and the UE, and the UE determines whether the PDCCH needs to be monitored at the next On Duration of the auxiliary DRX after the UE configures the auxiliary WUS parameter information. In this embodiment, the configuration of the auxiliary WUS is realized only by adding a new PS-RNTI, so that signaling overhead can be significantly reduced, and meanwhile, the UE detects the DCI of the WUS at the same time, so that power consumption can also be reduced.

In a fifth specific embodiment of step S22, the auxiliary WUS parameter information may include at least a PS-RNTI corresponding to the auxiliary WUS DCI, timeslot information for detecting the auxiliary WUS DCI, CORESET for detecting the auxiliary WUS DCI, a search space located in the CORESET, and cell indication information, where the cell indication information indicates a serving cell to which the auxiliary WUS applies; the serving base station may send the secondary WUS parameter information to the UE, so that the UE determines a serving cell to which the secondary WUS is applicable according to the cell indication information, and On the serving cell to which the secondary WUS is applicable, detects secondary WUS DCI according to the secondary WUS parameter information, at this time, the secondary WUS DCI is transmitted to the UE through the serving cell to which the secondary WUS is applicable, and if the serving cell to which the secondary WUS DCI is applicable may include SCell4 and SCell5, the secondary WUS DCI may be transmitted through SCell4, at this time, the CORESET configuration corresponding to the secondary WUS DCI associates with SCell4, so that the UE may know in which serving cell the secondary WUS DCI is detected, and then the UE parses bit information indicating the detected PDCCH in the secondary WUS DCI, and determines whether monitoring of the PDCCH needs to be performed at a next On Duration of the secondary DRX.

In a specific implementation, for the serving cell group to which the secondary DRX applies, WUS detection may be configured On one serving cell in the serving cell group to which the secondary DRX applies, and a corresponding CORESET and a search space may be configured, at this time, an independent WUS DCI detection parameter, such as PS-RNTI, may be configured, slot information of the WUS (which may be an offset value with respect to the immediately On Duration start time) may be detected, and a CORESET of the WUS and a corresponding search space may be detected.

In the embodiment of the invention, the UE determines the auxiliary WUS parameters by configuring the auxiliary WUS parameter information, so that the service base station can configure the auxiliary WUS parameter information for the UE according to information interaction with the UE, and the UE determines whether to monitor the PDCCH at the next On Duration of the auxiliary DRX after the UE configures the auxiliary WUS parameter information.

It should be noted that, in another specific embodiment, the auxiliary WUS parameter information may at least include a PS-RNTI corresponding to the auxiliary WUS DCI, timeslot information for detecting the auxiliary WUS DCI, CORESET for detecting the auxiliary WUS DCI, a search space located in the CORESET, bit information applicable to the auxiliary WUS in the WUS DCI, and cell indication information, where the cell indication information is used to indicate a serving cell applicable to the auxiliary WUS; the serving base station may send the auxiliary WUS parameter information to the UE, so that the UE determines a serving cell to which the auxiliary WUS is applicable according to the cell indication information, detects, On the serving cell, the auxiliary WUS DCI according to the auxiliary WUS parameter information, parses bit information indicating a detection PDCCH in the auxiliary WUS DCI, and then determines, according to the bit information applicable to the auxiliary WUS in the WUS DCI, whether a next On Duration is required to monitor the PDCCH in the serving cell to which the auxiliary WUS is applicable.

Different from the foregoing embodiment, after the UE configures the secondary WUS parameter information, the UE may determine the corresponding bit value by providing the bit information applicable by the secondary WUS in the WUS DCI, so as to determine whether to monitor the PDCCH at the next On Duration of the secondary DRX.

For more details of the bit information, please refer to the description of table 1, which is not described herein.

In a sixth specific embodiment of step S22, the secondary WUS parameter information may include at least applicability information indicating whether the primary WUS is applicable to the primary DRX serving cell and the secondary DRX serving cell; the serving base station may send the applicable information to the UE, so that the UE determines whether the main WUS is applicable to the main DRX serving cell and the auxiliary DRX serving cell, and when it is determined that the main WUS is applicable to at least one of the main DRX serving cell and the auxiliary DRX serving cell, detects the WUS DCI, then parses bit information indicating a detection PDCCH in the WUS DCI, and determines whether monitoring of the PDCCH at a next On Duration of DRX corresponding to the applicable main DRX serving cell and the auxiliary DRX serving cell is required. In this embodiment, the configuration of the auxiliary WUS is implemented by adding the applicable information, so that the signaling overhead can be significantly reduced.

It can be understood that, in addition to the applicable information, the UE may use a preset value, may directly use a parameter value predefined in the protocol, and may also use a parameter value of the main WUS parameter.

In a specific implementation, only one WUS configuration may be employed, with the serving base station configuring whether the WUS is applicable to the first DRX serving cell, or the second DRX serving cell, or both. When the configuration is "all", it can be considered as indicating that the main WUS is applicable to both the main DRX serving cell and the secondary DRX serving cell, and when the UE detects that the DCI of the WUS indicates that the PDCCH needs to be detected, it needs to monitor the PDCCH On the serving cell to which the DRX applies in the On Duration immediately following the first DRX, and at the same time, it needs to monitor the PDCCH On the serving cell to which the DRX applies in the On Duration immediately following the second DRX.

In the embodiment of the invention, the UE determines the auxiliary WUS parameters by configuring the auxiliary WUS parameter information, so that the service base station can configure the applicable information for the UE according to the information interaction between the service base station and the UE, and the UE determines whether the PDCCH needs to be monitored at the next On Duration of the auxiliary DRX after the UE configures the auxiliary WUS parameter information.

In the embodiment of the invention, the service base station configures the auxiliary WUS parameters for the UE based on the request information of the UE, so that the provided auxiliary WUS parameters can better meet the requirements of the UE and have pertinence.

In the present invention, the serving cell to which the primary DRX (i.e. the first DRX) is applicable may be one serving cell or a plurality of serving cells; the serving cell to which the secondary DRX (i.e., the second DRX) is applicable may be one serving cell or a plurality of serving cells. For the UE, the secondary DRX may be one or more, such as corresponding secondary DRX may be set separately per SCell, and a secondary WUS applicable to each SCell.
