Detailed Description

So that the manner in which the features and technical contents of the embodiments of the present application can be understood in detail, a detailed description of the embodiments of the present application will be given below with reference to the accompanying drawings, which are provided for illustration purposes and are not intended to limit the embodiments of the present application.

Before the measurement method provided in the embodiment of the present application, first, DRX in a New Radio (NR) system is briefly described.

In the NR system, the network device may configure a DRX function for the terminal device. The terminal device is enabled to monitor a Physical Downlink Control Channel (PDCCH) discontinuously, thereby achieving the purpose of saving power for the terminal device. Each MAC entity has a DRX configuration; the configuration parameters of DRX comprise:

1) a DRX duration Timer (DRX-onDuration Timer) which is a 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) A DRX deactivation timer (DRX-inactivity timer), when the terminal device receives a PDCCH indicating uplink initial transmission or downlink initial transmission, the terminal device continues to monitor the duration of the PDCCH.

4) A DRX downlink retransmission timer (DRX-retransmission timerdl) that is the maximum duration for which the terminal device monitors a PDCCH indicating downlink retransmission scheduling. Each downlink HARQ process except for a broadcast Hybrid Automatic Repeat reQuest (HARQ) process corresponds to one DRX-retransmission timerdl.

5) A DRX uplink retransmission timer (DRX-retransmission timer ul) that is the maximum duration for which the terminal device monitors the PDCCH indicating uplink retransmission scheduling. Each uplink HARQ process corresponds to one DRX-retransmission timerll.

6) DRX long cycle start offset (DRX-LongCycleStartOffset): a subframe offset for configuring a Long DTX Cycle (Long DRX Cycle), and a start of the Long DRX Cycle and a Short DRX Cycle (Short DRX Cycle).

7) DRX short cycle (DRX-short cycle) is an optional configuration.

8) A DRX Short cycle timer (DRX-ShortCycleTimer) is an optional configuration, the duration that the terminal device is in a Short DRX cycle (and does not receive any PDCCH).

9) A terminal device expects to receive the minimum waiting time required by a PDCCH (physical Downlink control channel) indicating downlink scheduling, and each downlink HARQ process except a broadcast HARQ process corresponds to a DRX-HARQ-RTT-TimerDL;

10) DRX-HARQ-RTT-TimerUL, the minimum waiting time required for the terminal equipment to expect to receive the PDCCH indicating the uplink scheduling, and each uplink HARQ process corresponds to one DRX-HARQ-RTT-TimerUL.

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

1) any one of the following 5 timers is running: a discontinuous reception duration timer (DRX-onDurationTimer), a discontinuous reception deactivation timer (DRX-inactivity timer), a discontinuous reception downlink retransmission timer (DRX-retransmission timer dl), a discontinuous reception uplink retransmission timer (DRX-retransmission timer ul), and a contention resolution timer (ra-ContentionResolutionTimer).

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

3) In the contention-based random access process, the terminal device does not receive primary initial transmission of a PDCCH indication scrambled by a Cell Radio Network Temporary Identifier (C-RNTI) after successfully receiving a random access response.

DRX long DRX is a default configuration, and DRX short DRX is an optional configuration. For the terminal device configured with the short DRX cycle, the conversion 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 times out;

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 times out;

2) the terminal equipment receives a long DRX command MAC CE.

The terminal device determines the time for starting the DRX-onDurationTimer according to whether the terminal device is currently in a short DRX cycle or a long DRX cycle, and the specific specification is as follows:

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

or, if Long DRX Cycle is used and the current subframe satisfies [ (SFN × 10) + subframe number ] module (DRX-LongCycle) ═ DRX-StartOffset;

2) the drx-onDurationTimer is started at a time instant after drx-SlotOffset slots from the start of the current subframe.

Fig. 1 shows a DRX cycle diagram of a terminal device, where a network device configures a Wake Up Signal (WUS) function for the terminal device, and the network notifies the terminal device whether to start a DRX-onDurationTimer to monitor a PDCCH by sending the WUS to the terminal device before the DRX-onDurationTimer start time.

In the NR Rel-16 Power saving (Power saving) standardization process, it is determined that the WUS mechanism is to be introduced during connected-state DRX. The main function of the WUS is to instruct the terminal device whether to start at the DRX-onDurationTimer at the start-up time corresponding to each DRX cycle to blindly detect the PDCCH. In the WUS based DRX procedure, the following conclusions are formed:

1. the WUS monitors the WUS at a WUS monitoring occasion (monitoring occasion) that is before the DRX-onDurationTimer start time corresponding to the DRX cycle based on the PDCCH design.

2. If WUS monitoring event is within the DRX activation time of the terminal device, the terminal device does not monitor the WUS.

3. If WUS monitoring oscillation is located during the terminal device's measurement gap, the terminal device does not listen to the WUS.

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

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

6. If the terminal device detects a WUS and the WUS instructs the terminal device to wake up, the terminal device normally starts the DRX-onDurationTimer at a subsequent DRX-onDurationTimer start-up time.

7. If the terminal device detects a WUS and the WUS indicates that the terminal device is not awake, the terminal device does not start the DRX-onDurationTimer at a subsequent DRX-onDurationTimer start-up time.

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

In order to support mobility management of the terminal device, the network device may send a CSI-RS to the terminal device, and the terminal device performs RRM measurement and/or Radio Link Monitoring (RLM) based on the CSI-RS.

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

Although the WUS affects the DRX activation time of the terminal device by instructing the terminal device to the on-state of the DRX-onDurationTimer within each DRX cycle, since the terminal device performs RRM measurement based on CSI-RS only for the DRX activation time; therefore, the introduction of the WUS mechanism will cause the terminal device to perform RRM measurement time based on CSI-RS to be reduced, so that the terminal device cannot perform RRM measurement based on CSI-RS comprehensively, for example, currently, the terminal device can only perform RRM measurement based on CSI-RS during DRX activation time, and if the WUS indicates that the terminal device does not wake up, the terminal device does not start DRX-onDurationTimer; this may result in the terminal device being in DRX inactivity for the DRX duration; currently, the terminal device will not perform RRM measurement based on the CSI-RS for the DRX duration, so the time for the terminal device to perform RRM measurement based on the CSI-RS is reduced, thereby affecting the accuracy of RRM measurement performed by the terminal device based on the CSI-RS.

Moreover, if the network device configures the same CSI-RS resource for RRM measurement and RLM for the terminal device, since the network device only transmits the CSI-RS within the DRX activation time, the time that the terminal device can perform RLM measurement may also be reduced, thereby affecting the accuracy of RLM measurement performed by the terminal device based on the CSI-RS.

In summary, when the terminal device configures the WUS, how the terminal device performs RRM measurement based on the CSI-RS can perform the RRM measurement based on the CSI-RS comprehensively, and thus improving the RRM measurement accuracy based on the CSI-RS is a problem to be solved.

An optional processing 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 active time or the measurement active time.

In some embodiments, the measurement activation time is a time that a first timer runs; the first timer is configured for the terminal equipment by the network equipment.

In some embodiments, the start time of the first Timer is the same as the start time of the DRX on duration Timer; the duration of the first timer may be configured by a network device through Radio Resource Control (RRC) signaling; the duration of the first Timer may not be configured by the network device, but may be the same as the duration of the DRX on duration Timer by default. Wherein, the operation time of the DRX duration Timer is the DRX activation time.

In some embodiments, for the case that the start time of the first Timer is the same as the start time of the DRX on duration Timer, the start state of the first Timer may be unrelated to the start state of the DRX on duration Timer, that is, at the start time of the DRX on duration Timer, the terminal device starts the first Timer regardless of whether the DRX on duration Timer is started or not. In this scenario, when the terminal device is in DRX active time or the terminal device is in measurement active time, the terminal device performs measurement based on a channel state information reference signal; i.e. the terminal device is in any of the DRX active time and the measurement active time, the terminal device performs RRM measurement based on the CSI-RS.

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

In still other embodiments, 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 CSI-RS in the measurement activation period.

In the embodiment of the present application, when the terminal device configures DRX and a current DRX cycle is greater than a first time, the terminal device does not expect to obtain available csi-rs resources at times other than the DRX active time and the measurement active time. The first time may be 80ms, and the first time may also be configured to be a value other than 80ms according to the actual situation.

The following describes in detail a procedure in which the terminal device performs the CSI-RS based RRM measurement for different scenarios, respectively.

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

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 parameter at least comprises: long DRX cycle, short DRX cycle, DRX on Timer, and first Timer. The WUS related parameters at least comprise WUS listening opportunity (monitoring opportunity); for example, a WUS monitoring occasion is configured on at least one downlink BWP of a Primary Cell (PCell).

In the embodiment of the application, the starting time of the first Timer is the same as the starting time of the DRX on duration Timer; the duration of the first timer can be configured by the network device through an RRC signaling; the duration of the first Timer may not be configured by the network device, but may be the same as the duration of the DRX on duration Timer by default. The starting state of the first Timer is irrelevant to the starting state of the DRX on duration Timer, that is, at the starting time of the DRX on duration Timer, the terminal device starts the first Timer regardless of whether the DRX on duration Timer is started.

In step S302, the terminal device determines the WUS monitoring state based on the WUS monitoring event of the RRC configuration information before the start time of the DRX operation Timer corresponding to the DRX cycle, and determines the start state of the DRX operation Timer according to the WUS monitoring state.

In some embodiments, if the terminal device does not monitor the WUS at the WUS monitoring occasion prior to the start time of the DRX duration Timer, the terminal device normally starts the DRX duration Timer at a subsequent DRX duration Timer start time.

In other embodiments, if the terminal device monitors the WUS at a WUS monitoring occasion prior to the start time of the DRX on duration Timer, the terminal device further determines whether the terminal device starts the DRX on duration Timer at a subsequent DRX on duration Timer start time based on the WUS monitoring result.

Step S303, the terminal device starts a first timer.

In some embodiments, the condition for the terminal device to start the first timer comprises: the terminal device configures the WUS on the currently activated downlink BWP, and reaches the starting time of a DRX duration Timer corresponding to the DRX cycle. As shown in fig. 4, the terminal configures a WUS on a currently activated downlink BWP, and reaches a start time of a DRX on duration Timer corresponding to a DRX cycle, and regardless of whether the DRX on duration Timer is started, the terminal starts the first Timer.

Here, the first Timer is operated for the measurement active time, and the DRX on duration Timer is operated for the DRX active time.

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

For example, if the DRX on Timer is not started at the time of starting the DRX on Timer corresponding to the DRX cycle, and only the first Timer is started, the terminal device performs the RRM measurement based on the CSI-RS at the measurement activation time during which the first Timer is operated. Such as the terminal device performing SCI-RS based RRM measurements based on the CSI-RS-Resource-Mobility configuration.

For example, if the DRX on Timer corresponding to the DRX cycle is started, the DRX on Timer and the first Timer are started; the terminal device performs RRM measurement based on the CSI-RS at the measurement activation time or the 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 the embodiment of the present application, when the terminal device configures DRX and a current DRX cycle is greater than 80ms, the terminal device does not expect to obtain available csi-rs resources at a time other than the DRX active time and the measurement active time. Otherwise, the terminal equipment assumes that the corresponding CSI-RS Resource can be obtained based on the CSI-RS-Resource-Mobility configuration.

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

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 application, the starting time of the first Timer is the same as the starting time of the DRX on duration Timer; the duration of the first timer can be configured by the network device through an RRC signaling; the duration of the first Timer may not be configured by the network device, but may be the same as the duration of the DRX on duration Timer by default. The starting state of the first Timer is related to the starting state of the DRX duration Timer, namely at the starting time of the DRX duration Timer, if the DRX duration Timer is started, the terminal equipment does not start the first Timer; and at the starting time of the DRX duration Timer, if the DRX duration Timer is not started, the terminal equipment starts a first Timer.

Step S402, the terminal equipment determines the WUS monitoring state based on the WUS monitoring event before the starting time of the DRX duration Timer corresponding to the DRX cycle by the RRC configuration information, and determines the starting state of the DRX duration Timer according to the WUS monitoring 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 comprises: the terminal device configures the WUS on the currently activated downlink BWP, and reaches the starting time of a DRX duration Timer corresponding to the DRX cycle. Another schematic diagram of the terminal device starting the first Timer is shown in fig. 5, where the terminal device configures a WUS on a currently activated downlink BWP and reaches a starting time of a DRX on duration Timer corresponding to a DRX cycle, and if the DRX on duration Timer is started, the terminal device does not start the first Timer; and at the starting time of the DRX duration Timer, if the DRX duration Timer is not started, the terminal equipment starts a first Timer.

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

For example, if the DRX on Timer is started at the starting time of the DRX on Timer corresponding to the DRX cycle, the terminal device does not start the first Timer, and the terminal device performs the RRM measurement based on the CSI-RS at the DRX activation time during which the DRX on Timer is operated. Such as the terminal device performing SCI-RS based RRM measurements based on the CSI-RS-Resource-Mobility configuration.

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

Still another schematic diagram of the terminal device starting the first timer is shown in fig. 6, where the terminal device configures the WUS on the currently activated downlink BWP and reaches the start time of the first timer, and the terminal device starts the first timer.

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