For better understanding of the embodiments of the present application, the 5G NR DRX related to the present application will be described.

In the 5G NR, the network device may configure a DRX function for the terminal, and the network device configures a DRX cycle (cycle) for the terminal in a Radio Resource Control (RRC) connected state. As shown in fig. 2, the DRX cycle includes an active period (On Duration) and a dormant period (Opportunity for DRX), and during the On Duration, the terminal device monitors and receives a Physical Downlink Control Channel (PDCCH); during Opportunity for DRX time, the terminal device does not receive the PDCCH to reduce power consumption.

Wherein, each MAC entity has a DRX configuration, and the configuration parameters of DRX comprise:

DRX state duration timer (DRX-onDurationTimer): duration of terminal device wake-up at the beginning of one DRX Cycle (Cycle);

DRX slot offset (DRX-SlotOffset): the terminal equipment starts the time delay of the drx onDurationTimer;

DRX deactivation timer (DRX-inactivity timer): after receiving a PDCCH indicating uplink initial transmission or downlink initial transmission, the terminal equipment continues to monitor the duration of the PDCCH;

DRX downlink retransmission timer (DRX-retransmission timerdl): the terminal equipment monitors the longest duration of the PDCCH indicating the downlink retransmission scheduling. Each downlink HARQ process except for a broadcast Hybrid Automatic Repeat reQuest (HARQ) process corresponds to a drx-retransmission timerdl;

DRX uplink retransmission timer (DRX-retransmission timer ul): the terminal equipment monitors the longest duration of a PDCCH indicating uplink retransmission scheduling. Each uplink HARQ process corresponds to one drx-retransmission TimerUL;

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

DRX short cycle (DRX-short cycle): short DRX cycle, which is optional configuration;

DRX short cycle timer (DRX-ShortCycleTimer): the duration that the terminal device is in Short DRX cycle (and does not receive any PDCCH), which is an optional configuration;

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

DRX uplink HARQ RTT timer (DRX-HARQ-RTT-timerll): and the terminal equipment expects to receive the minimum waiting time required by the PDCCH indicating the uplink scheduling, and each uplink HARQ process corresponds to one drx-HARQ-RTT-TimerUL.

If the terminal device configures DRX, the terminal device needs to monitor PDCCH during DRX Active Time (Active Time). DRX Active Time includes several cases:

case 1: any one of 5 timers, drx-onDurationTimer, drx-inactivytimetr, drx-retransmission timerdl, drx-retransmission timerll, and random access contention resolution timer (ra-ContentionResolutionTimer), is running.

Case 2: a Scheduling Request (SR) is transmitted on a Physical Uplink Control Channel (PUCCH) and is in a waiting (pending) state.

Case 3: in the contention-based random access process, the terminal device does not receive one initial transmission indicated by a PDCCH scrambled by a Cell Radio Network Temporary identifier (C-RNTI) after successfully receiving a random access response.

Note that the DRX long cycle (DRX long cycle) is a default configuration, and the DRX short cycle (DRX short cycle) is an optional configuration. For a terminal configured with a short DRX cycle, the long DRX cycle and the short DRX cycle can be mutually converted, and the conversion mode is as follows:

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

drx-inactivity timer times out;

the terminal device receives a DRX Command (Command) Media Access Control Element (MAC CE).

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

drx-ShortCycleTimer times out;

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:

if Short DRX Cycle is used, and the current subframe satisfies [ (System Frame Number, SFN) × 10) + subframe Number (subframe Number) ] mod (DRX-Short) = (DRX-StartOffset) mod (DRX-Short); or

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

wherein the DRX-onDurationTimer is started at a time after a DRX slot offset (DRX-SlotOffset) slots (slots) from the start of the current subframe.

The conditions for starting or restarting the drx-inactivytytytytimer by the terminal equipment are as follows:

if the terminal equipment receives a PDCCH indicating the downlink or uplink initial transmission, the terminal starts or restarts the drx-InactivetyTimer.

The conditions for starting and stopping the drx-retransmission timerdl by the terminal equipment are as follows:

when the terminal device receives a PDCCH indicating downlink transmission, or when the terminal device receives a Media Access Control Protocol Data Unit (MAC PDU) on the configured downlink grant resource, the terminal device stops drx-retransmission timerdl corresponding to the HARQ process. And the terminal equipment starts drx-HARQ-RTT-TimerDL corresponding to the HARQ process after finishing the transmission of the HARQ process feedback aiming at the downlink transmission.

If a timer drx-HARQ-RTT-TimerDL corresponding to a certain HARQ of the terminal device is overtime and the downlink data transmitted by using the HARQ process is unsuccessfully decoded, the terminal starts drx-retransmission TimerDL corresponding to the HARQ process.

The conditions for starting and stopping drx-retransmission timerll by the terminal equipment are as follows:

when the terminal equipment receives a PDCCH indicating uplink transmission or when the terminal equipment sends a MAC PDU on the configured uplink authorized resource, the terminal stops drx-retransmission TimerUL corresponding to the HARQ process. The terminal device starts drx-HARQ-RTT-timer ul corresponding to the HARQ process after completing the first retransmission (retransmission) of the Physical Uplink Shared Channel (PUSCH) of this time.

If a timer drx-HARQ-RTT-timerll corresponding to a certain HARQ of the terminal device is overtime, the terminal starts drx-retransmission timerll corresponding to the HARQ process.

Release16, R16 introduces Dual DRX, but it cannot be configured with DCP, i.e., if the network configures DCP, it cannot. In order to enable Dual DRX and DCP to be configured simultaneously, the DCP needs to be enhanced because currently, the DCP can only indicate one DRX-on duration timer corresponding to one DRX.

Based on the above problem, the present application provides a scheme for discontinuous reception, which can reduce unnecessary PDCCH monitoring on part or all DRX groups by a terminal device using a DCP under the condition that a plurality of DRX groups are configured for one MAC entity, thereby achieving the purpose of saving power for the terminal.

The technical solution of the present application is described in detail by specific examples below.

Fig. 3 is a schematic flow chart of a method 200 of discontinuous reception according to an embodiment of the present application, and as shown in fig. 3, the method 200 may include at least some of the following:

s210, a network device sends first information, wherein the first information is used for indicating at least one DRX group controlled by a DCP, and the at least one DRX group comprises a primary DRX group and/or a secondary DRX group;

s220, the terminal equipment receives the first information.

In the embodiment of the present application, at least two DRX groups may be configured for one MAC entity, where the at least two DRX groups may include one Primary DRX group (Primary DRX group) and at least one Secondary DRX group (Secondary DRX group).

That is, the first information may indicate whether a DRX group controlled by the DCP is a Primary DRX group or a Secondary DRX group, or indicate that the DCP controls both the Primary DRX group and the Secondary DRX group.

For further example, the first information indicates a DRX state duration timer corresponding to a Primary DRX group controlled by the DCP.

For another example, the first information indicates a DRX state duration timer corresponding to a Secondary DRX group controlled by the DCP.

For a further example, the first information indicates a DRX state duration timer corresponding to a Primary DRX group and a DRX state duration timer corresponding to a Secondary DRX group controlled by the DCP.

It should be noted that a DRX group is actually one or more serving cells, and a DRX group including a Special Cell (SpCell) is a primary DRX group, and a DRX group including only a Secondary Cell (SCell) is a Secondary DRX group. And the serving cells in the same DRX group adopt the same DRX configuration.

Optionally, the embodiments of the present application may be applied to a Carrier Aggregation (CA) scenario.

Optionally, the first information is RRC signaling. Alternatively, the first information is carried in an RRC signaling.

Optionally, in some embodiments, in a case that the terminal device receives the DCP, the terminal device determines, according to the first information, to start a DRX state duration timer corresponding to the at least one DRX group at a first time, where the first time is a time for starting the DRX state duration timer.

It should be noted that the first time is a time when the DRX state duration timer is started after receiving the DCP.

For example, in a case where the at least one DRX group includes a primary DRX group, the terminal device determines to start a DRX state duration timer corresponding to the primary DRX group at the first time.

For another example, in a case that the at least one DRX group includes a secondary DRX group, the terminal device determines to start a DRX state duration timer corresponding to the secondary DRX group at the first time.

For another example, in a case where the at least one DRX group includes a primary DRX group and a secondary DRX group, the terminal device determines to start a DRX state duration timer corresponding to the primary DRX group and a DRX state duration timer corresponding to the secondary DRX group at the first time.

Optionally, in some embodiments, in case that the terminal device receives the DCP, for DRX groups configured in the MAC entity other than the at least one DRX group, the terminal device may determine to start or not start its corresponding DRX state duration timer at the first time. That is, the terminal device may determine to start or not start a DRX state duration timer corresponding to a DRX group other than the at least one DRX group configured in the MAC entity at the first time.

For example, the terminal device may determine to start or not start a DRX state duration timer corresponding to a DRX group other than the at least one DRX group configured in the MAC entity at the first time according to the preconfiguration information.

Optionally, in some embodiments, in a case that the terminal device does not receive the DCP, the terminal device determines to start or not start a DRX state duration timer corresponding to a DRX group configured in the MAC entity at a first time, where the first time is a time when the DRX state duration timer is started.

For example, the terminal device determines to start or not start a DRX state duration timer corresponding to the DRX group configured in the MAC entity at the first time according to the pre-configuration information.

Optionally, the pre-configuration information is pre-configured by the network device, or the pre-configuration information is agreed by a protocol.

When it is necessary to say, the provisioning information may also be default configuration information or default configuration information.

Optionally, in some embodiments, the terminal device may determine whether to monitor the DCP at the DCP monitoring occasion (monitoring occasion) according to the first information and a DRX state of the terminal device at the DCP monitoring occasion.

For example, if the first information indicates that the DCP controls Primary DRX group, then: if the terminal device is in a Primary DRX group for Active Time (Active Time) during DCP monitoring occasion, the terminal device does not monitor the DCP on the DCP monitoring occasion.

For another example, if the first information indicates that the DCP controls the secondary DRX group, then: if the terminal device is in the second DRX group at DRX Active Time during DCP monitoring occasion, the terminal device does not monitor the DCP on the DCP monitoring occasion.

For another example, if the first information indicates that the DCP controls a Primary DRX group and a Secondary DRX group, then:

the method comprises the following steps: if the terminal device is in the Primary DRX group or the Secondary DRX group at DRX Active Time during DCP monitoring occasion, the terminal device does not monitor the DCP on the DCP monitoring occasion.

The method 2 comprises the following steps: if the terminal device is in DRX Active Time in both Primary DRX group and Secondary DRX group during DCP monitoring occasion, the terminal device does not monitor DCP on the DCP monitoring occasion.

Therefore, in the embodiment of the present application, the network device may indicate at least one DRX group controlled by the DCP, and the at least one DRX group includes a primary DRX group and/or a secondary DRX group. That is to say, the application can achieve the purpose of reducing unnecessary PDCCH monitoring on part or all DRX groups by the terminal device by using the DCP when configuring a plurality of DRX groups for one MAC entity, thereby achieving the purpose of saving power for the terminal. Meanwhile, the scheme of the application has small influence on the standard.
