Description

Technical field

Background technique

In the new radio system (New Radio-based access to unlicensed spectrum, NR-U) on the unlicensed spectrum, the terminal equipment adopts the DRX mechanism to realize its energy saving. The network device can configure the terminal device to "wake up" at a predetermined time and monitor the downlink control channel when it wakes up, or it can configure the terminal device to "sleep" at the time that the network device predicts, and do not need to monitor the downlink control channel during sleep.

The wireless communication system 100 may include a plurality of network devices, and the coverage area of each network device may include other numbers of terminal devices. In addition, the wireless communication system 100 may also include other network entities such as a network controller and a mobility management entity.

When NR works in unlicensed spectrum, for example, it can include the following scenarios: Carrier Aggregation (CA) scenario, Dual Connectivity (DC) scenario, Standalone (SA) deployment scenario, NR single cell scenario Wait.

Generally speaking, the working frequency band (Band) of NR-U is 5GHz unlicensed spectrum and 6GHz unlicensed spectrum. On the unlicensed spectrum, the design of NR-U should ensure fairness with other systems that already work on these unlicensed spectrums, such as Wireless Fidelity (WiFi). That is, the impact of NR-U on systems that have been deployed on unlicensed spectrum cannot exceed the impact between these systems.

In order to ensure fair coexistence between systems on unlicensed spectrum, energy detection has been agreed as a basic coexistence mechanism. The general energy detection mechanism is the LBT mechanism. The basic principle of the mechanism is that the transmitter needs to listen for a period of time according to regulations before transmitting data on the unlicensed spectrum. If the result of the listening indicates that the channel is idle, the transmitting end can transmit data to the receiving end. If the listening result indicates that the channel is in an occupied state, the transmitting end needs to back off for a period of time according to regulations before continuing to listen to the channel until the channel listening result is idle before transmitting data to the receiving end.

In NR, the network device can configure the DRX switching function for the terminal device, so that the terminal device discontinuously monitors the Physical Downlink Control Channel (PDCCH), and the terminal device can periodically enter the sleep state at certain times. Do not monitor the PDCCH, but wake up from the sleep state when the PDCCH needs to be monitored, so that the terminal device can save power.

Figure 2 is a schematic diagram of a typical DRX cycle (DRX Cycle). As shown in Fig. 2, the T1 period is the wake-up time of the terminal device, which is called On Duration, and the T2 period is the sleep time of the terminal device, which may be called the DRX opportunity (Opportunity for DRX). The wake-up duration of the terminal device can be controlled by a DRX duration timer (drx-onDurationTimer), and the timing duration of the DRX duration timer is T1. The terminal device needs to continuously monitor the PDCCH during the wake-up time T1, but may not monitor the PDCCH during the sleep time T2. The longer the T2 time, the lower the energy consumption of the terminal equipment.

It can be seen from Figure 2 that for the long DRX cycle (DRX long cycle), the terminal device wakes up less frequently, so it is more power-efficient for the terminal device; while for the short DRX cycle (DRX short cycle), the terminal device’s A higher wake-up frequency will increase the energy consumption of the terminal device, but it can increase the probability of the network device successfully scheduling the terminal device and reduce the data transmission delay.

Each Medium Access Control (MAC) entity corresponds to a DRX configuration. The DRX configuration may include the aforementioned DRX duration timer. In addition, the DRX configuration may also include other DRX timers, so as to jointly adjust the wake-up time of the terminal device. The other DRX timers include, for example:

The DRX inactivity timer (drx-InactivityTimer) indicates how long it needs to continue monitoring after the terminal device successfully detects the PDCCH;

The short DRX cycle timer (drx-ShortCycleTimer) indicates the duration of the terminal device following the short DRX cycle;

The DRX downlink retransmission timer (drx-RetransmissionTimerDL) is used for the terminal device to receive the downlink retransmission schedule, indicating the length of time that the terminal device needs to continuously monitor in order to receive the desired downlink retransmission schedule;

DRX downlink hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) round-trip time (Round-Trip Time, RTT) timer (HARQ-RTT-TimerDL) is used by the terminal device to receive the downlink retransmission schedule, indicating that the terminal device receives the expectation The length of time to wait before the downlink retransmission scheduling.

In addition, the network device can also configure other DRX parameters for the terminal device, such as short DRX cycle (drx-ShortCyc), long DRX cycle, DRX start subframe offset (drx-LongCycleStartOffset), DRX slot offset (drx -SlotOffset), etc.; and configure other DRX timers, such as random access contention resolution timer (ra-ContentionResolutionTimer), DRX uplink retransmission timer (drx-RetransmissionTimerUL), DRX uplink HARQ round trip time timer (HARQ-RTT- TimerUL) and so on.

In the existing DRX mechanism, the long DRX cycle is the default configuration, and the short DRX cycle is an optional configuration. For terminal devices configured with a short DRX cycle, the conversion between the long DRX cycle and the short DRX cycle can be performed in the following ways:

When any of the following conditions are met, the terminal device uses the short DRX cycle: (1) The DRX inactivity timer (drx-InactivityTimer) expires; (2) The terminal device receives the DRX command MAC CE (DRX Command MAC CE);

When any of the following conditions are met, the terminal device uses the long DRX cycle: (1) the short DRX cycle timer (Drx-shortCycleTimer) expires; (2) the terminal device receives the long DRX command MCA CE (long DRX command MAC CE).

Whether it is a long DRX cycle or a short DRX cycle, the active time of the terminal device includes the following situations:

(1) DRX duration timer (drx-onDurationTimer), DRX inactivity timer (drx-InactivityTimer), DRX downlink retransmission timer (drx-RetransmissionTimerDL), DRX uplink retransmission timer (drx-RetransmissionTimerUL) and random Any one of the access contention resolution timers (ra-ContentionResolutionTimer) is running;

(2) The terminal device sends (Scheduling Request, SR) on PUCCH and is pending (pending);

(3) The Hybrid Automatic Repeat Request (HARQ) of the terminal device has data in the buffer and waits for an uplink grant (UL grant) for HARQ retransmission;

(4) The terminal device successfully receives a random access response (Random Access Response, RAR) in response to a preamble that is not selected by the MAC entity, but does not receive an indication of the initial transmission of the cell wireless network temporary using the MAC entity. Identifies the PDCCH (Cell Radio Network Temporary Identifier, C-RNTI).

In NR-U, due to the uncertainty of signal transmission on the unlicensed spectrum, it may happen that the network device expects to schedule the terminal device during the Active Time of the terminal device but cannot schedule the terminal because the channel on the unlicensed spectrum is unavailable. Circumstances, thereby increasing the service delay and affecting user experience. Therefore, if the terminal device does not monitor any downlink transmission during the wake-up period based on the long DRX cycle, it can automatically switch the long DRX cycle to the short DRX cycle.

However, for the terminal device, when no downlink data is detected, it may be that the network device originally expected to schedule the terminal device at the time the terminal device "woke up", but the terminal device cannot be scheduled because the channel is not available, or it may be a network device No downlink data is sent to the terminal device. The terminal device cannot distinguish the above two situations. If the network device does not send downlink data to the terminal device, the terminal device switches from a long DRX cycle to a short DRX cycle, which will increase unnecessary energy consumption.

The embodiment of the present application proposes a DRX-based data transmission method, which can effectively control the "wake-up" of the terminal device, and while improving the data transmission performance, it takes into account the energy consumption of the terminal device.

Fig. 3 is a DRX-based data transmission method according to an embodiment of the present application. The method 300 shown in FIG. 3 may be executed by a terminal device and a network device. The terminal device is, for example, the terminal device 120 shown in FIG. 1, and the network device is, for example, the network device 110 shown in FIG. 1. As shown in FIG. 3, the method 300 includes all or part of the following steps.

In 310, the network device sends the first indication information to the terminal device.

In 320, the terminal device receives the first indication information sent by the network device.

Wherein, the first indication information is used to indicate activation or deactivation of the DRX switching function.

In 330, the terminal device activates or deactivates the DRX switching function according to the first indication information.

Among them, the DRX switching function is: when the terminal device does not detect the downlink transmission based on the long DRX cycle, it automatically switches the long DRX cycle to the short DRX cycle.

When the DRX switching function is activated, if the terminal device does not monitor the downlink transmission within the activation time, for example, during the timing of the DRX-onDurationTimer (drx-onDurationTimer), it can automatically switch the long DRX cycle to the short DRX cycle; When the DRX switching function is deactivated, if the terminal device does not monitor the downlink transmission during the activation time, for example, during the DRX-onDurationTimer (drx-onDurationTimer) timing period, the terminal device will not automatically switch the long DRX cycle to the short DRX cycle, but continue to use long DRX cycle.

In this embodiment, the network device may determine whether to activate or deactivate the DRX switching function according to the requirements of the terminal device, such as energy saving requirements or channel quality, and indicate to the terminal device through the first indication information. The terminal device activates or deactivates its DRX switching function according to the instructions of the first indication information, so that the DRX switching function matches its requirements, and reduces unnecessary energy consumption while ensuring data transmission performance.

The first indication information may be carried in, for example, radio resource control (Radio Resource Control, RRC) signaling or medium access control (Medium Access Control, MAC) control element (Control Element, CE).

In the embodiment of the present application, the network device can determine whether to activate or deactivate the DRX switching function of the terminal device in the following two ways.

Way 1

As shown in FIG. 4, before 310, the method further includes some or all of 340, 350, and 360.

In 340, the terminal device sends the second indication information to the network device.

In 350, the network device receives the second indication information sent by the terminal device.

Wherein, the second indication information is used to indicate whether the terminal device needs to save energy.

In 360, the network device determines the first indication information according to the second indication information.

For example, when the second indication information indicates that the terminal device needs to save energy, the first indication information is used to indicate to deactivate the DRX switching function; when the second indication information indicates that the terminal device does not need to save energy, the first indication information is used to indicate activation The DRX switching function.

In this embodiment, the network device determines whether to activate or deactivate the DRX switching function of the terminal device based on the energy-saving requirements of the terminal device, so that the DRX switching function matches the energy-saving requirements of the terminal device, and avoids the DRX switching function from bringing to the terminal device Unnecessary energy consumption.

If the DRX switching function is currently active, and the terminal device currently has energy saving requirements, for example, when the terminal device is currently in a low battery, the terminal device may send second indication information to the network device to indicate that it expects to save energy. After receiving the second instruction information, the network device sends the first instruction information to the terminal device to instruct the terminal device to deactivate the DRX switching function, so that the terminal device deactivates its DRX switching function based on the first instruction information to save energy consumption.

If the DRX switching function is currently in the deactivated state and the terminal device currently has no energy saving requirement, the terminal device may send the second indication information to the network device to indicate that it has no energy saving requirement. After receiving the second instruction information, the network device sends the first instruction information to the terminal device to instruct the terminal device to activate the DRX switching function, so that the terminal device activates its DRX switching function based on the first instruction information to ensure timely reception of the network device scheduling Data, reduce data transmission delay.

The second indication information may be carried in RRC signaling, MAC CE, or PDCCH, for example.

Optionally, in 340, the terminal device needs to send the second indication information after the DRX switching timer expires.

Further, the terminal device starts or restarts the DRX switching time timer when sending the second indication information.

In order to avoid the terminal device from frequently sending the second indication information, the network device may configure the DRX switching timer for the terminal device. For example, the network device may configure the DRX switching timer through RRC signaling. The timing duration of the DRX switching timer is the minimum time interval for the terminal device to report the second indication information. After the DRX switching timer expires, the terminal device can send the second indication information to the network device based on its own power saving requirement, where each time the second indication information is sent, the terminal device restarts the DRX switching timer.

Way 2

As shown in FIG. 5, before 310, the method further includes some or all of 370, 380, and 390.

In 370, the terminal device reports the measurement result of the reference signal.

The measurement result includes, for example, reference signal receiving power (Reference Signal Receiving Power, RSRP) and/or reference signal receiving quality (Reference Signal Receiving Quality, RSRQ) measurement results.

In 380, the network device receives the measurement result reported by the terminal device.

In 390, the network device determines the first indication information according to the measurement result.

In this embodiment, the terminal device measures the reference signal, obtains the measurement result, and reports it. The network device determines whether to activate or deactivate the DRX switching function of the terminal device based on the signal measurement result of the terminal device, so that the DRX switching function is matched with the current channel quality, and the data transmission performance is improved while taking into account the energy consumption of the terminal device.

The signal measurement result reported by the terminal device may be the measurement result of the RSRP and RSRQ of the reference signal in the cell by the terminal device. The embodiments of this application do not make any limitation on these measurement quantities. Any measurement quantity that can reflect the channel quality can be used to determine whether to activate or deactivate the DRX switching function.

For example, the terminal equipment measures RSRP and RSRQ of the reference signal. When the network device determines that the RSRP is less than the first RSRP threshold and/or the RSRQ is less than the first RSRQ threshold, the first indication information is used to instruct to activate the DRX switching function; the network device determines that the RSRP is greater than the second RSRP threshold and/or the RSRQ When it is greater than the second RSRQ threshold, the first indication information is used to indicate to deactivate the DRX switching function.

Wherein, when the measured RSRP is less than or equal to the first RSRP threshold, RSRQ is less than or equal to the first RSRQ threshold, or RSRP is less than or equal to the first RSRP threshold and RSRQ is less than or equal to the first RSRQ threshold, it indicates that the current channel quality is poor Therefore, it is necessary to increase the opportunity for terminal equipment to receive downlink data. At this time, the network device instructs the terminal device to activate the DRX switching function through the first indication information, so that when the terminal device does not detect downlink data during the activation period, it automatically switches from the long DRX cycle to the short DRX cycle, which increases the success of data scheduling. Rate, to ensure that the downlink data can be received in time.

When the measured RSRP is greater than or equal to the second RSRP threshold, RSRQ is greater than or equal to the second RSRQ threshold, or RSRP is greater than or equal to the second RSRP threshold and RSRQ is greater than or equal to the second RSRQ threshold, it indicates that the current channel quality is good. At this time, the network device instructs the terminal device to deactivate its DRX switching function through the first indication information, thereby reducing the energy consumption of the terminal device.

The above method 1 considers the power saving requirements of the terminal equipment. The network equipment determines whether the terminal device has the current power saving requirement to activate or deactivate the DRX switching function, which better meets the power saving requirements of the user. Method 2 considers the current channel quality. For terminal equipment with insufficient channel quality, instruct it to activate the DRX switching function, and automatically switch from the long DRX cycle to the short DRX cycle when no downlink data is detected based on the long DRX cycle. , To increase the wake-up frequency, thereby increasing the probability of successfully receiving downlink data.

Fig. 6 is a DRX-based data transmission method according to another embodiment of the present application. The method 600 shown in FIG. 6 may be executed by a terminal device and a network device. The terminal device is, for example, the terminal device 120 shown in FIG. 1, and the network device is, for example, the network device 110 shown in FIG. 1. As shown in FIG. 6, the method 600 includes all or part of the following steps.

In 610, the terminal device activates or deactivates the DRX switching function.

In this embodiment, the terminal device may independently determine whether to activate or deactivate its DRX switching function without an instruction from the network device. Compared with the method shown in Figure 3, the signaling overhead of this method is smaller.

In an implementation manner, the terminal device may activate or deactivate the DRX switching function according to the signal measurement result.

The terminal equipment measures the reference signal and obtains the measurement result. The terminal device determines whether to activate or deactivate its DRX switching function according to the signal measurement result, so that the DRX switching function matches the current channel quality, improves data transmission performance, and takes into account the energy consumption of the terminal device.

For example, when the terminal device measures the RSRP and RSRQ of the reference signal and determines that the RSRP is less than the first RSRP threshold and/or the RSRQ is less than the first RSRQ threshold, the terminal device activates the DRX switching function; the terminal device determines that the RSRP is greater than the second RSRP threshold And/or when the RSRQ is greater than the second RSRQ threshold, the terminal device deactivates the DRX switching function.

Wherein, when the measured RSRP is less than or equal to the first RSRP threshold, RSRQ is less than or equal to the first RSRQ threshold, or RSRP is less than or equal to the first RSRP threshold and RSRQ is less than or equal to the first RSRQ threshold, it indicates that the current channel quality is poor Therefore, it is necessary to increase the chance of terminal equipment receiving the channel. At this time, the terminal device activates its DRX switching function, so that when the terminal device does not detect downlink data during the activation period, it automatically switches from long DRX to short DRX cycle, which increases the success rate of data scheduling and ensures that the downlink data can be Receive in time.

When the measured RSRP is greater than or equal to the second RSRP threshold, RSRQ is greater than or equal to the second RSRQ threshold, or RSRP is greater than or equal to the second RSRP threshold and RSRQ is greater than or equal to the second RSRQ threshold, it indicates that the current channel quality is good. At this time, the terminal device deactivates its DRX switching function, thereby reducing unnecessary energy consumption.

In another implementation manner, the terminal device can activate or deactivate the DRX switching function based on its own energy saving requirements.

For example, the terminal device deactivates the DRX switching function when energy saving is required, and activates the DRX switching function when there is no energy saving requirement. If the DRX switching function is currently active, and the terminal device currently has energy saving requirements, for example, when the terminal device is currently in low power, the terminal device can deactivate its DRX switching function to save energy consumption. If the DRX switching function is currently in a deactivated state, and the terminal device currently has no energy saving requirement, the terminal device can activate its DRX switching function to ensure timely reception of data scheduled by the network device and reduce data transmission delay.

Optionally, after 610, the method further includes 620 and 630.

In 620, the terminal device sends third indication information.

In 630, the network device receives the third indication information.

Wherein, the third indication information is used to indicate that the terminal device activates or deactivates the DRX switching function.

When activating or deactivating the DRX switching function, the terminal device may send third indication information to the network device to inform the network device that it has activated or deactivated the DRX switching function autonomously. The third indication information may be, for example, the measurement report of the aforementioned signal measurement, or may also be display indication signaling such as RRC signaling or MAC CE.

It should be understood that when the terminal device autonomously activates or deactivates its DRX switching function, in addition to determining whether to activate or deactivate the DRX switching function through signal measurement results, it may also autonomously determine whether to activate or deactivate the DRX switching function through other methods.

Optionally, before 310, the method further includes: the network device sends configuration information to the terminal device. Wherein, the configuration information includes DRX configuration parameters and/or signal measurement information. Correspondingly, the terminal device receives the configuration information.

The DRX configuration parameter includes at least one of the following: long DRX cycle information, short DRX cycle information, and DRX duration timer (drx-onDurationTimer) information.

In addition, the DRX configuration parameters may also include the aforementioned other DRX timers.

The signal measurement information includes, for example, at least one of the following: a measurement object, a measurement quantity, a reporting method of a measurement result, and a measurement threshold.

Among them, the measurement object includes, for example, the serving cell measured by the terminal device; the measurement quantity includes, for example, RSRP, RSRQ, SINR, etc.; the method of reporting the measurement result includes, for example, periodic reporting or event-triggered reporting; the measurement threshold is used to determine whether to activate or The deactivation of the DRX switching function can be, for example, the aforementioned first RSRP threshold, second RSRP threshold, first RSRQ threshold, and second RSRQ threshold.

The configuration information sent by the network device to the terminal device may be carried in RRC signaling. After the terminal device receives the DRX configuration parameter sent by the network device, it executes the DRX mechanism based on the DRX configuration parameter and activates the DRX switching function. Here, it can be assumed that the DRX switching function is initially active.

Of course, the DRX switching function can also be initially in the deactivated state by default, and the terminal device will not activate the DRX switching function after receiving the DRX configuration parameters sent by the network device, but will make the DRX switching function in the deactivated state.

Alternatively, whether the DRX switching function is initially activated or deactivated can be instructed by the network device.

For example, the network device may display and instruct the terminal device to activate or deactivate the DRX switching function through RRC signaling. When the terminal device receives the RRC signaling, it can not only obtain the DRX configuration parameters from it, but also obtain an indication information, which is used to indicate whether the DRX switching function is activated. If the indication information indicates to activate the DRX switching function, the terminal device sets the initial DRX switching function to be activated, and if the indication information indicates to deactivate the DRX switching function, the terminal device sets the initial DRX switching function to be inactivated.

For another example, when the indication information defaults, it may indicate that the DRX switching function is initially in a deactivated state. That is, if the terminal device does not obtain the indication information, it can be considered that the DRX switching function is initially in a deactivated state.
