Detailed Description

For a more complete understanding of the nature and the technical content of the embodiments of the present application, reference should be made to the following detailed description of embodiments of the present application in connection with the accompanying drawings, which are provided for purposes of illustration only and are not intended to limit the embodiments of the present application.

Before the measurement method provided in the embodiments of the present application, a brief description will be first made of DRX in a New Radio (NR) system.

In an NR system, a network device may configure a DRX function for a terminal device. The terminal equipment discontinuously monitors the physical downlink control channel (Physical Downlink Control Channel, PDCCH), so that the purpose of saving electricity of the terminal equipment is achieved. Each MAC entity has a DRX configuration; the configuration parameters of DRX include:

1) A DRX duration Timer (DRX-onDuration Timer), the duration for which the terminal device wakes up at the beginning of one DRX Cycle (Cycle).

2) DRX slot offset (DRX-SlotOffset), the terminal device starts the delay of DRX-onDuration Timer.

3) And a DRX deactivation Timer (DRX-activity Timer), wherein after the terminal equipment receives a PDCCH indicating uplink initial transmission or downlink initial transmission, the terminal equipment continues to monitor the duration of the PDCCH.

4) DRX downlink retransmission timer (DRX-retransmission timer): the terminal device listens for the longest duration of the PDCCH indicating the downlink retransmission schedule. Each downlink hybrid automatic repeat request (HARQ) process except for the broadcast Hybrid Automatic Repeat reQuest HARQ process corresponds to one DRX-Retransmission TimerDL.

5) DRX uplink retransmission timer (DRX-retransmission timer ul): the terminal device listens for the longest duration of the PDCCH indicating the uplink retransmission schedule. Each uplink HARQ process corresponds to one DRX-Retransmission TimerUL.

6) DRX long cycle start offset (DRX-longcyclstartoffset): for configuring a Long DRX Cycle (Long DRX Cycle), and subframe offsets at which the Long DRX Cycle and Short DRX Cycle (Short DRX Cycle) start.

7) DRX short cycle (DRX-short): is an alternative configuration.

8) DRX short cycle timer (DRX-shortcycle): the duration that the terminal device is in Short DRX cycle (and does not receive any PDCCH) is an optional configuration.

9) DRX-HARQ-RTT-TimerDL: the terminal equipment expects to receive the minimum waiting time required by the PDCCH indicating the downlink scheduling, and each downlink HARQ process except the broadcast HARQ process corresponds to one DRX-HARQ-RTT-TimerDL;

10 DRX-HARQ-RTT-TimerUL): the terminal device expects to receive the minimum waiting time required for indicating the PDCCH of the uplink scheduling, and each uplink HARQ process corresponds to one drx-HARQ-RTT-TimerUL.

If the terminal equipment is configured with the DRX function, the terminal equipment needs to monitor the PDCCH at the DRX Active Time. The DRX Active Time includes the following cases:

1) Any one of the following 5 timers is running: discontinuous reception duration timer (DRX-onduration timer), discontinuous reception deactivation timer (DRX-InactigityTimer), discontinuous reception downlink retransmission timer (DRX-retransmission Timer DL), discontinuous reception uplink retransmission timer (DRX-retransmission Timer UL), and contention resolution timer (ra-Contention resolution timer).

2) The SR is transmitted on the PUCCH and is in a pending (pending) state.

3) In the contention-based random access procedure, the terminal device has not received one initial transmission of the cell radio network temporary identity (Cell Radio Network Temporary Identifier, C-RNTI) scrambled PDCCH indication after successful reception of the random access response.

DRX long DRX is a default configuration, and DRX short DRX is an optional configuration. For the terminal equipment configured with the short DRX cycle, the switching mode between the long DRX cycle and the short DRX cycle is as follows:

the terminal device uses the DRX short cycle when any one of the following conditions is satisfied:

1) DRX-InactivityTimer timeout;

2) The terminal receives a DRX Command MAC CE.

The terminal uses the DRX long cycle when any one of the following conditions is satisfied:

1) DRX-ShortCycleTimer timeout;

2) The terminal device receives a long DRX command MAC CE.

The terminal device decides the time for starting the DRX-onduration timer according to whether the terminal device is currently in the short DRX cycle or the long DRX cycle, and specifically specifies the following steps:

1) If Short DRX Cycle is used, and the current subframe satisfies [ (SFN x 10) +subframe number ] module (DRX-Shortcycle) = (DRX-StartOffset) module (DRX-Shortcycle);

alternatively, if Long DRX Cycle is used, and the current subframe satisfies [ (sfn×10) +subframe number ] module (DRX-LongCycle) =drx-StartOffset;

2) The drx-onduration timer is started at a time after the drx-SlotOffset slot at the beginning of the current subframe.

The DRX cycle diagram of the terminal device, as shown in fig. 1, where the network device configures a wake-up signal (WakeUpSignal, WUS) function for the terminal device, and the network informs the terminal device whether to start the DRX-onduration timer to monitor the PDCCH by sending WUS to the terminal device before the DRX-onduration timer start time.

In the NR Rel-16 power saving (power save) normalization procedure, it is determined that the WUS mechanism is to be introduced in the connected DRX procedure. The main function of WUS is to indicate whether the terminal device starts at the DRX-onduration timer at the starting time of the DRX-onduration timer corresponding to each DRX cycle to blindly detect the PDCCH. In WUS-based DRX procedures, the following conclusions are formed:

1. WUS is based on PDCCH design, and the terminal device listens to WUS at WUS listening occasions (monitoring occasion) before the DRX-onduration timer start-up time corresponding to the DRX cycle.

2. If WUS monitoring occasion is within the terminal's DRX activation time, the terminal does not monitor WUS.

3. If WUS monitoring occasion is located during the measurement gap of the terminal device, the terminal device does not listen to WUS.

4. The terminal device does not listen to WUS during the bandwidth part (BandWidthPart, BWP) handover.

5. If the terminal device does not monitor WUS, the terminal device normally starts the DRX-ondurationTimer at the subsequent DRX-ondurationTimer start time.

6. If the terminal device detects WUS and WUS indicates that the terminal device wakes up, the terminal device normally starts DRX-onduration timer at a subsequent DRX-onduration timer start time.

7. If the terminal device detects WUS and WUS indicates that the terminal device does not wake up, the terminal device does not start DRX-onduration timer at a subsequent DRX-onduration timer start time.

8. If the terminal device does not detect WUS, the terminal device decides whether to start DRX-onduration timer at a subsequent DRX-onduration timer start time based on the configuration of the network device.

To support mobility management of the terminal device, the network device may send CSI-RS to the terminal device, which may perform RRM measurements and/or radio link monitoring (Radio link monitoring, RLM) based on the CSI-RS.

If the terminal device is configured with the DRX function, the terminal device performs the CSI-RS based RRM measurement only during the DRX activation time. And, if the terminal device is configured with a DRX function and the currently used DRX cycle is greater than 80ms, the terminal device does not expect to obtain available CSI-RS resources at other times than the DRX activation time; otherwise, the terminal equipment can obtain corresponding CSI-RS resources based on the CSI-RS-Resource-mobility configuration.

Although WUS affects the DRX activation time of the terminal device by indicating the start-up state of the DRX-onduration timer in each DRX cycle, since the terminal device performs CSI-RS based RRM measurement only in the DRX activation time; therefore, the introduction of WUS mechanism will cause the terminal device to perform the reduction of RRM measurement time based on CSI-RS, so that the terminal device cannot perform RRM measurement based on CSI-RS comprehensively, for example, at present, the terminal device can only perform RRM measurement based on CSI-RS in DRX activation time, and if WUS indicates that the terminal device is not awake, the terminal device does not start DRX-onduration timer; this may result in the terminal device being at DRX inactive time for the DRX duration; at present, the terminal equipment does not execute RRM measurement based on the CSI-RS in the DRX duration, so that the time for the terminal equipment to execute the RRM measurement based on the CSI-RS is reduced, and the accuracy of the terminal equipment to execute the RRM measurement based on the CSI-RS is further affected.

And if the network device configures the same resource of the CSI-RS for the terminal device for RRM measurement and RLM, since the network device only transmits the CSI-RS in the DRX activation time, the time during which the terminal device can perform RLM measurement is also reduced, thereby affecting the accuracy of RLM measurement performed by the terminal device based on the CSI-RS.

In summary, under the condition that the terminal equipment configures WUS, how to perform RRM measurement based on CSI-RS by the terminal equipment can comprehensively perform RRM measurement based on CSI-RS, so that improving RRM measurement accuracy based on CSI-RS is a problem to be solved.

Alternatively, the 5G system or 5G network may also be referred to as an NR system or NR network.

An optional process flow of the measurement method provided in the embodiment of the present application, as shown in fig. 3, includes the following steps:

in step S201, the terminal device performs RRM measurement based on the channel state information reference signal at the DRX activation time or the measurement activation time.

In some embodiments, the measured activation time is a time at which the first timer is running; wherein the first timer is configured by the network device for the terminal device.

In some embodiments, the start time of the first timer is the same as the start time of DRX Onduration Timer; the duration of the first timer may be configured by the network device via radio resource control (Radio Resource Control, RRC) signaling; the duration of the first timer may be the same as the duration of DRX Onduration Timer by default, instead of being configured by the network device. The running time of DRX Onduration Timer is the DRX activation time.

In some embodiments, for the case where the start time of the first timer is the same as the start time of DRX Onduration Timer, the start state of the first timer may be uncorrelated with the start state of DRX Onduration Timer, i.e., at the start time of DRX Onduration Timer, the terminal device will start the first timer regardless of whether DRX Onduration Timer is started. In this scenario, when the terminal device is at a DRX active time or the terminal device is at a measurement active time, the terminal device performs measurement based on a channel state information reference signal; i.e., the terminal device is at any one of the DRX activation time and the measurement activation time, the terminal device performs the CSI-RS based RRM measurement.

In other embodiments, the start state of the first timer may be related to the start state of DRX Onduration Timer for the case where the start time of the first timer is the same as the start time of DRX Onduration Timer; that is, at the start time of DRX Onduration Timer, if DRX Onduration Timer is started, the first timer is not started; or at the start time of DRX Onduration Timer, if DRX Onduration Timer is not started, the first timer is started. When DRX Onduration Timer is running, the terminal device is in a DRX activation period, and then the terminal device performs RRM measurement based on the CSI-RS in the DRX activation period. When the first timer runs, the terminal equipment is in a measurement activation period, and then the terminal equipment performs RRM measurement based on the CSI-RS in the measurement activation period.

In yet other embodiments, both the duration of the first timer and the starting time of the first timer may be configured by the network device through RRC signaling. In the scene, the terminal equipment starts the first timer based on the configuration of the network equipment; when the first timer runs, the terminal equipment is in a measurement activation period, and the terminal equipment only performs RRM measurement based on the CSI-RS in the measurement activation period.

In this embodiment of the present application, in a case where the terminal device configures DRX and the current DRX cycle is greater than the first time, the terminal device does not expect to obtain available channel state information reference signal resources at a time other than the DRX activation time and the measurement activation time. The first time may be 80ms, and the first time may also be configured to be other values than 80ms according to practical situations.

The following describes in detail a procedure of performing CSI-RS based RRM measurement by a terminal device for different scenarios, respectively.

For a scenario in which the starting time of the first timer is the same as the starting time of DRX Onduration Timer and the starting state of the first timer is irrelevant to the starting state of DRX Onduration Timer, the process of performing RRM measurement based on CSI-RS by the terminal device includes:

in step S301, the terminal device receives RRC configuration information sent by the network device, and configures DRX related parameters and WUS related parameters.

Wherein, the DRX related parameters at least comprise: long DRX cycle, short DRX cycle, DRX Onduration Timer and a first timer. The WUS related parameters include at least WUS listening occasions (monitoring occation); such as WUS monitoring occation, on at least one downlink BWP of a primary Cell (PCell).

In the embodiment of the present application, the starting time of the first timer is the same as the starting time of DRX Onduration Timer; the duration of the first timer can be configured by the network equipment through RRC signaling; the duration of the first timer may be the same as the duration of DRX Onduration Timer by default, instead of being configured by the network device. The start state of the first timer is not related to the start state of DRX Onduration Timer, i.e. at the start time of DRX Onduration Timer, the terminal device starts the first timer regardless of whether DRX Onduration Timer is started.

In step S302, the terminal device determines the WUS listening state based on WUS monitoring occation of the RRC configuration information before the starting time of DRX Onduration Timer corresponding to the DRX cycle, and determines DRX Onduration Timer the starting state according to the WUS listening state.

In some embodiments, if the WUS is not monitored by the terminal device WUS monitoring occation prior to the boot time of DRX Onduration Timer, the terminal device boots up DRX Onduration Timer normally at the subsequent DRX Onduration Timer boot time.

In other embodiments, if the terminal device monitors WUS WUS monitoring occation before the start-up time of DRX Onduration Timer, the terminal device further determines whether the terminal device is started up DRX Onduration Timer at the start-up time of DRX Onduration Timer based on the WUS monitoring result.

In step S303, the terminal device starts a first timer.

In some embodiments, the condition for the terminal device to start the first timer includes: the terminal device configures WUS on the currently activated downlink BWP and reaches the start time of DRX Onduration Timer corresponding to the DRX cycle. As shown in fig. 4, the terminal device configures WUS on the currently activated downlink BWP and reaches the starting time of DRX Onduration Timer corresponding to the DRX cycle, and starts the first timer regardless of whether DRX Onduration Timer is started or not.

Here, the time the first timer is operated is a measurement activation time, and the time the DRX Onduration Timer is operated is a DRX activation time.

In step S304, the terminal device performs RRM measurement based on CSI-RS at the DRX activation time or the measurement activation time.

For example, if the first timer is only started without starting DRX Onduration Timer at the starting time of DRX Onduration Timer corresponding to the DRX cycle, the terminal device performs RRM measurement based on CSI-RS at the measurement activation time of the first timer operation. The terminal device performs SCI-RS based RRM measurements based on the CSI-RS-Resource-Mobility configuration, for example.

For example, if DRX Onduration Timer and the first timer are started at the starting time of DRX Onduration Timer corresponding to the DRX cycle; the terminal device performs CSI-RS based RRM measurement at the measurement activation time or DRX activation time. It can be understood that the terminal device performs the CSI-RS based RRM measurement as long as there is one of the measurement active time and the DRX active time.

In this embodiment of the present application, in the case where the terminal device configures DRX and the current DRX cycle is greater than 80ms, the terminal device does not expect to obtain available channel state information reference signal resources at a time other than the DRX activation time and the measurement activation time. Otherwise, the terminal equipment can obtain corresponding CSI-RS resources based on the CSI-RS-Resource-Mobility configuration.

For a scenario in which the starting time of the first timer is the same as the starting time of DRX Onduration Timer, and the starting state of the first timer is related to the starting state of DRX Onduration Timer, the process of performing RRM measurement based on CSI-RS by the terminal device includes:

in step S401, the terminal device receives RRC configuration information sent by the network device, and configures DRX related parameters and WUS related parameters.

In the embodiment of the present application, the starting time of the first timer is the same as the starting time of DRX Onduration Timer; the duration of the first timer can be configured by the network device through RRC signaling; the duration of the first timer may be the same as the duration of DRX Onduration Timer by default, instead of being configured by the network device. The start state of the first timer is related to the start state of the DRX Onduration Timer, that is, at the start time of DRX Onduration Timer, if DRX Onduration Timer is started, the terminal device does not start the first timer; at the start time of DRX Onduration Timer, if DRX Onduration Timer is not started, the terminal device starts the first timer.

In step S402, the terminal device determines the WUS listening state based on WUS monitoring occation of the RRC configuration information before the starting time of DRX Onduration Timer corresponding to the DRX cycle, and determines DRX Onduration Timer the starting state according to the WUS listening state.

In step S403, the terminal device starts a first timer.

In some embodiments, the condition for the terminal device to start the first timer includes: the terminal device configures WUS on the currently activated downlink BWP and reaches the start time of DRX Onduration Timer corresponding to the DRX cycle. As shown in fig. 5, the terminal device configures WUS on the currently activated downlink BWP and reaches the starting time of DRX Onduration Timer corresponding to the DRX cycle, and if DRX Onduration Timer is started, the terminal device does not start the first timer; at the start time of DRX Onduration Timer, if DRX Onduration Timer is not started, the terminal device starts the first timer.

In step S404, the terminal device performs RRM measurement based on CSI-RS at the DRX activation time or the measurement activation time.

For example, if the terminal device starts DRX Onduration Timer at the start time of DRX Onduration Timer corresponding to the DRX cycle, the terminal device does not start the first timer, and the terminal device performs RRM measurement based on CSI-RS at the DRX activation time operated at DRX Onduration Timer. The terminal device performs SCI-RS based RRM measurements based on the CSI-RS-Resource-Mobility configuration, for example.

In an example, if the start is not DRX Onduration Timer at the start time of DRX Onduration Timer corresponding to the DRX cycle, the terminal device starts a first timer; the terminal device performs the CSI-RS based RRM measurement at the measurement activation time of the first timer run.

For the scenario that both the duration of the first timer and the starting time of the first timer are configured by the network device through the RRC signaling, the process of the terminal device executing the CSI-RS based RRM measurement includes:

in step S501, the terminal device receives RRC configuration information sent by the network device, and configures DRX related parameters and WUS related parameters.

In the embodiment of the application, the starting time and the starting duration of the first timer are configured by the network equipment; the configuration parameters of the first timer may be carried in an RRM measurement configuration. In specific implementation, the network device may configure the starting time and the starting duration of the first timer, and may also configure the starting period and the starting duration of the first timer.

In step S502, the terminal device determines the WUS listening state based on WUS monitoring occaion of the configuration information before the starting time of DRX Onduration Timer corresponding to the DRX cycle, and determines DRX Onduraion Timer the starting state according to the WUS listening state.

In other embodiments, if the terminal device monitors WUS WUS monitoring occation before the start-up time of DRX Onduration Timer, the terminal device further determines whether the terminal device is started up DRX Onduration Timer at the start-up time of DRX Onduraion Timer based on the WUS monitoring result.

In step S503, the terminal device periodically starts the first timer based on the configuration parameters of the first timer.

As shown in fig. 6, the terminal device configures WUS on the currently activated downlink BWP and reaches the starting time of the first timer, and starts the first timer.

In step S504, the terminal device performs RRM measurement based on CSI-RS at the measurement activation time.

In some embodiments, when the terminal device starts the first timer, the time the first timer runs is a measurement activation time, and the terminal device performs RRM measurement based on CSI-RS at the measurement activation time. The terminal device performs SCI-RS based RRM measurements based on the CSI-RS-Resource-Mobility configuration, for example.

An alternative process flow of the measurement method provided in the embodiment of the present application, as shown in fig. 7, includes the following steps:

in step S601, the network device sends configuration information of the first timer to the terminal device.

The configuration information is used for the terminal equipment to execute RRM measurement based on the channel state information reference signal at DRX activation time or measurement activation time, and the measurement activation time is the time when the first timer runs.

In some embodiments, the configuration information includes: the duration of the first timer. Optionally, the starting time of the first timer is the same as the starting time of the DRX continuous timer; the DXR duration timer is operated for the DRX activation time.

In other embodiments, the configuration information includes: the starting time of the first timer and the duration of the first timer.

In the embodiment of the application, the measurement activation time corresponding to the first timer in running is introduced, and the network equipment can send the CSI-RS to the terminal equipment in the measurement activation time; the terminal device may also perform CSI-RS based RRM measurements at the measurement activation time. In this way, in the case that the terminal device is configured with WUS, the terminal device can perform CSI-RS based RRM measurements also in the DRX duration; the time of RRM measurement of the terminal equipment based on the CSI-RS is increased, the influence of the introduction of WUS on the RRM measurement of the terminal equipment based on the CSI-RS is avoided, and the RRM measurement accuracy of the terminal equipment based on the CSI-RS is improved.
