Detailed Description

Example embodiments will now be described more fully hereinafter with reference to the accompanying drawings.

It should be noted that the exemplary embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein.

Based on the background technology, the existing scheme cannot be well adapted for certain service scenes, and transmission delay and energy-saving effect are not ideal.

The inventor finds that the reason why the transmission delay and the energy-saving effect are not ideal is that some services have non-integer period and/or jitter characteristics, and the existing scheme cannot be well adapted to the non-integer period and/or jitter characteristics.

The services that are not well adapted may include XR (augmented reality) services, immersive XR, holographic communication, autopilot, digital twinning, meta universe, etc.

The characteristic information of the service may include a non-integer period, a service packet size, a service jitter characteristic, and the like.

For simplicity of description, XR service is taken as an example hereinafter.

Currently, AR/VR (augmented reality and virtual reality) is one of important application scenarios/services in 5G, and with the development of technology, AR/VR will be comprehensively evolved to XR (augmented reality) in 5G-Advanced and 6G ages.

The inventors have found that XR traffic has the need for high transmission rates, low latency and high reliability, which presents a significant challenge for existing networks. Accordingly, the inventors began studies on capacity boosting and energy saving for XR services.

In addition, for XR devices (e.g., XR glasses), the size and weight design will determine whether the device can be worn for extended periods of time. There will be more restrictions on battery capacity and heat dissipation than conventional terminals. Therefore, reducing the energy consumption of high-speed transmission XR services is one of the main directions of standard research.

The NR supports the discontinuous transmission DRX terminal energy saving technology, but the existing scheme cannot be well adapted to the characteristic of the non-integer period of the XR service, and transmission delay and energy saving effect are not ideal.

Therefore, it is required to enhance the period configuration of the existing connection state discontinuous transmission C-DRX, better adapt to the non-integer period requirement of the XR new service, and reduce the delay and the terminal energy consumption.

In order to adapt to the non-integer period and jitter characteristic of XR service in the implementation of the present disclosure, the network side configures the open DRX parameter adjustment for the user equipment, and dynamically adjusts the DRX parameter configuration according to the transmission condition of the XR service.

For ease of understanding, the following description first refers to the related art and terms of NR DRX related to this disclosure as follows:

RRC signaling configures up to 2 sets of DRX configurations for a cell. The configuration information includes on Duration, DRX Cycle, inactivity-timer, retransmission-timer, active-time, etc., and each User Equipment (UE) uses a set of DRX configurations.

on Duration: the UE maintains awake time after each wake-up from DRX, during which the UE monitors the PDCCH.

DRX Cycle: consisting of a wake-up time and a sleep time, and is repeated periodically, as shown in fig. 1.

The inactivity-timer: the duration of time that the UE remains awake after successfully demodulating the PDCCH; if the PDCCH demodulation fails, the method returns to the sleep state according to the original sleep time.

retransmission-timer: for receiving the duration of the retransmission.

active-time: the UE listens for the total duration of the PDCCH. Including the "on Duration" time, the "activity-timer" time, and the "retransmission-timer" time of the DRX cycle.

Currently, each UE supports at most two sets of DRX parameters, including different on Duration and long and short periods, but only one set of DRX parameters is used by the UE.

It should be noted that, in the embodiment of the present disclosure, the user equipment includes, but is not limited to, a mobile phone, a tablet computer, a notebook, an in-vehicle communication device, an unmanned aerial vehicle, a communication module on the unmanned aerial vehicle, a remote control plane, an aircraft, a mini-plane, a vehicle, an RSU, a wireless sensor, an internet of things terminal, an RFID terminal, an NB-IOT terminal, an MTC (Machine Type Communication ) terminal, an eMTC (enhanced MTC) terminal, a data card, an internet card, an in-vehicle communication device, a low-cost mobile phone, a low-cost tablet computer, and other wireless communication devices.

The network-side device in the embodiments of the present disclosure may be a base station (also referred to as a cell).

Base stations include, but are not limited to, macro cell base stations, micro cell base stations, small cell base stations, home base stations, relay base stations, enbs, gnbs, TRPs (Transmitter Receiver Point, transmitting and receiving nodes), GNSS, relay satellites, satellite base stations, air base stations, RSUs (Road Side units), unmanned aerial vehicles, test equipment, wireless communication equipment such as transceivers or signaling testers that simulate part of the functions of the base stations.

The present exemplary embodiment will be described in detail below with reference to the accompanying drawings and examples.

Fig. 2 shows a flowchart of a discontinuous reception configuration method in an embodiment of the present disclosure, and as shown in fig. 2, the discontinuous reception configuration method provided in the embodiment of the present disclosure includes the following steps:

s202, the network side sends signaling to the user equipment, wherein the signaling comprises Discontinuous Reception (DRX) parameters.

The signaling sent by the network side to the user equipment may be at least one of RRC signaling, MAC CE signaling, DCI signaling.

The DRX parameter comprises at least one of a DRX adjustment factor and a DRX period, wherein the DRX period is a non-integer period. The DRX parameters are used for semi-static or dynamic configuration of DRX parameters of the user equipment and/or the DRX parameters are used for semi-static or dynamic adjustment of DRX parameter configuration of the user equipment.

In some examples, the DRX parameters may also include whether to turn on DRX adjustment and/or DRX adjustment thresholds.

The DRX parameters are determined by the network side based on target data related to the traffic of the user equipment, the target data including characteristic information of the traffic.

As one example, the characteristic information of the XR service includes non-integer periodic data of the XR service. The network layer may determine the DRX adjustment factor based on non-integer periodic data of the XR traffic.

Here, the service related to the user equipment may be at least one of XR service, immersive XR, holographic communication, autopilot, digital twin, meta universe, and the like.

The characteristic information of the service may include a non-integer period, a service packet size, a service jitter characteristic, etc. For example: in order to adapt to the integer period and jitter characteristic of XR service, the network side configures the starting DRX parameter adjustment for the user equipment, and dynamically adjusts the DRX parameter configuration according to the transmission condition of XR service.

In some examples, the present disclosure may also adjust the radio resource control, RRC, protocol such that the RRC protocol supports DRX non-integer cycle configuration. Thus, the DRX parameters in this disclosure may include a DRX cycle, which is a non-integer cycle.

S204, the user equipment executes discontinuous reception according to the DRX parameter.

Discontinuous reception (DRX, discontinuous Reception) packet-based data streams are typically bursty, with data transmission for a period of time, but no data transmission for a longer period of time following. When there is no data transmission, power consumption can be reduced by stopping receiving the PDCCH. The period is adjusted according to the DRX parameters in the present disclosure S204, so as to better adapt the traffic.

In some embodiments, the DRX adjustment factor may include a DRX offset or a DRX offset index value, the DRX offset index value being used to indicate the DRX offset.

In S204, discontinuous reception is performed according to the DRX parameter, which may be that the ue configures or adjusts the starting time of the DRX wakeup time in its DRX configuration according to the DRX parameter, and further performs discontinuous reception according to the adjusted DRX cycle.

In some embodiments, the method may further include adjusting a start time of a DRX wake-up time in a user equipment DRX configuration based on a DRX adjustment factor, or based on the DRX adjustment factor and a DRX adjustment threshold, in the case of an on DRX adjustment.

Here, the start time of the DRX wake-up time may be the start time of the DRX On duration or the start time of the DRX Cycle. The description of On duration and DRX Cycle is explained above with respect to NR DRX.

In some embodiments, in the case of turning on the DRX adjustment, the starting time of the DRX wake-up time in the user equipment DRX configuration is adjusted based on the DRX adjustment factor and the DRX adjustment threshold, which may be when the DRX offset is greater than or equal to the DRX adjustment threshold, based on the DRX offset or the DRX offset index value.

And when the DRX offset is smaller than the DRX adjustment threshold, not adjusting the starting time of the DRX wake-up time in the DRX configuration of the user equipment.

As an example, adjusting the start time of the DRX wake-up time in the DRX configuration of the user equipment based on the DRX offset or the DRX offset index value in the above embodiment may include:

selecting a target offset value from a preset offset index value and offset table based on the DRX offset index value;

and adjusting the starting time of the DRX wake-up time in the DRX configuration of the user equipment based on the target offset value.

The DRX offset is calculated by the network side according to the system frame number, the subframe number, the non-integer period data of the XR service, and the DRX period. The DRX offset may be included in the DRX parameters.

As an example, the network side may calculate the DRX offset by the following formula:

O＝floor{xr_cycle×floor[(SFN×10+subframe number)/drx_cycle]}-(SFN×10+subframe number)

Wherein, O represents DRX offset, floor represents a downward rounding function, xr_cycle represents non-integer period data of XR service, SFN represents system frame number, subframe number represents subframe number, and drx_cycle represents DRX period.

As an example, non-integer periodic data of XR traffic may be rounded down to obtain DRX cycle drx_cycle.

In some embodiments, the user equipment may calculate a start time of a DRX wake-up time in the DRX configuration of the user equipment according to the DRX cycle in the DRX parameter.

As an example, the user equipment may calculate a start time of a DRX wake-up time in the DRX configuration of the user equipment according to a system frame number, a subframe number, and a DRX cycle.

As another example, the user equipment may round down the DRX cycle, resulting in a DRX integer cycle; and then calculating to obtain the starting time of the DRX wake-up time in the DRX configuration of the user equipment according to the system frame number, the subframe number and the DRX integer period.

As yet another example, the user equipment may calculate the start time of the DRX wake-up time in the user equipment DRX configuration by the following formula:

T＝ceil{drx_cycle×floor[(SFN×10+subframe number)/drx_cycle]}

wherein T represents a start time of a wake-up time in a DRX configuration of the user equipment, ceil represents an upward rounding function, drx_cycle represents a DRX cycle, floor represents a downward rounding function, SFN represents a system frame number, and subframe number represents a subframe number.

The DRX parameter may be determined by the network side based on target data related to a service of the user equipment, the target data including characteristic information of the service.

Wherein the target data may originate from at least one of a core network, a user equipment, a base station, and a third party service provider.

As an example, the target data includes auxiliary configuration information reported by the user equipment, where the auxiliary configuration information includes at least one item of recommended configuration information in DRX related configuration, and is used to promote network adaptation XR service, promote system capacity, and perform network service collaborative optimization.

In some embodiments, the target data may further include at least one of the following information:

user equipment capability information, XR service information, network information.

As one example, the user equipment capability information may include at least one of the following data:

user equipment power saving requirements, user equipment power consumption levels, user equipment processing capabilities, user equipment computing capabilities, user equipment storage capabilities, user equipment support AI/ML capabilities, user equipment support machine learning capability classification, user equipment support business prediction capabilities.

As one example, the XR service information may include at least one of the following:

Service type, non-integer periodic data of XR service, XR service QoS/QoE requirement, XR service flow number, XR data packet size, service model prediction result and XR service information to be transmitted.

In the embodiment of the disclosure, the DRX parameter may be determined according to XR service information. As an example, according to the AI/ML supporting capability of the ue, when the ue supports AI/ML, the ue deploys an AI/ML model or algorithm to extract service feature information, predicts services such as XR, and recommends DRX parameter configuration or performs dynamic/semi-static adjustment of DRX configuration according to the prediction result, so as to enable collaborative optimization of network services.

In some examples, the network information may include at least one of the following:

the method comprises the steps of user equipment moving speed, wireless channel environment, network capability, data quantity to be transmitted in a network buffer zone, network time delay condition, network congestion condition and network load condition.

In the embodiment of the present disclosure, the DRX parameter sent by the S202 network side includes at least one of a DRX adjustment factor and a DRX cycle, where the DRX cycle is a non-integer cycle.

Wherein, when the DRX parameter comprises a DRX adjustment factor, DRX can adopt integer period configuration, and the DRX period starting time is adjusted semi-statically/dynamically.

When the DRX parameter comprises a DRX period, the DRX is configured for the non-integer period when the DRX period is the non-integer period. The present disclosure may adjust the radio resource control, RRC, protocol such that the RRC protocol supports DRX non-integer cycle configuration.

For ease of understanding, the process of determining DRX parameters at the network side in the embodiments of the present disclosure is described below in terms of DRX employing an integer period configuration and DRX employing a non-integer period configuration, respectively.

First, taking XR service as an example, DRX is described as an integer period configuration.

The following operations are performed when whether DRX adjustment is configured and/or the DRX adjustment factor is turned on.

And acquiring XR (non-integer periodic characteristics) xr_cycle of the XR service according to the XR service information, selecting DRX_cycle of the DRX according to the non-integer periodic characteristics, and adjusting a threshold L by DRX.

The DRX cycle drx_cycle may be obtained by rounding XR traffic non-integer cycle characteristics xr_cycle.

According to the system frame number SFN, the subframe number, xr_cycle, drx_cycle is calculated to obtain a DRX offset drx_startoffset (may also be referred to as a DRX cycle start offset) as the DRX parameter configuration, which specifically includes the following formula:

embodiments of the present disclosure may define/predefine a Table of offset index values and offsets (drx_startoffset_table), containing several offset value (drx_startoffset) selectable values. Wherein the offset value may be an integer.

As an example, the UE receives a DRX adjustment factor according to the signaling, where the dynamic adjustment factor is equal to a corresponding sequence number in drx_slotoffset or drx_startoffset_table, for adjusting the start time of the DRX on duration.

Optionally, the following operations are performed: when drx_slotoffset < L, no dynamic adjustment operation is performed; when drx_slotoffset > =l, a dynamic adjustment operation is performed.

The start time of drx onduration timer is configured after the start subframe drx_slotoffset.

In one example, DRX is configured as an integer period, DCI informs of the adjustment period start time.

Taking XR period 60fps (16.67 ms) as an example, the value of drx_cycle is 16ms, calculated according to the formula above. When the XR traffic arrival time coincides with the DRX on duration start time, the DRX cycle information calculated according to the foregoing formula is shown in fig. 3. The 3 rd DRX cycle start offset 1ms, the 4 th DRX cycle start offset 2ms, and the 4 th period XR traffic arrival time and the DRX cycle start time coincide again with each other by an additional offset 1ms compared to the previous period.

In another example, the DRX is configured as an integer period, a DRX on duration start time.

Taking XR period 60fps (16.67 ms) as an example, the value of drx_cycle is 16ms, calculated according to the formula above. The DRX on duration start time adjustment is increased and the DRX cycle information is shown in fig. 4. If the frame structure supports 30kHz, the dynamic factor adjustment threshold is set to l=2ms, drx_slotoffset is calculated, the 3 rd DRX cycle drx_slotoffset=1ms does not perform dynamic adjustment operation, the 4 th cycle drx_slotoffset=2ms > =dynamic factor adjustment threshold L, DCI adjustment on duration start time is sent, and offset is 2ms.

In the above example, the DRX integer period size is calculated according to XR service characteristics or feature extraction, the DRX cycle start offset is calculated according to the proposed formula, and the gNB sends the DRX integer period configuration information to the UE to complete DRX configuration. According to the scheme, the periodic configuration optimization is performed based on the XR characteristics, flexible and dynamic configuration can be realized according to different XR service characteristics and network environments, the extraction of the service characteristics and the DRX dynamic configuration can be performed through the introduction of an AI model, the effects of reducing time delay and saving energy of a terminal are achieved, and the data transmission capacity in an XR scene is improved.

Next, a configuration using DRX non-integer cycles is described.

The present disclosure defines/predefines DRX Cycle configurations such that the DRX Cycle supports XR traffic non-integer Cycle characteristics, i.e., the DRX Cycle supports non-integer Cycle configurations.

The UE calculates the DRX cycle starting time according to the DRX cycle in the DRX related configuration, namely calculates the DRX on duration starting time according to the system frame number SFN, subframe number and drx_cycle, and the formula is as follows:

ceil{drx_cycle×floor[(SFN×10+subframe number)/drx_cycle]}

for example: according to the above formula, taking the example that the DRX cycle is equal to 16.67ms, the DRX on duration start time is 0, 17, 34, 50 respectively, and the effect of 17/17/16 cycle configuration can be achieved.

In one example, DRX is configured as a non-integer period, calculated at the UE side.

Taking XR period 60fps (16.67 ms) as an example, the value of drx_cycle is 16.67ms. Assuming that the XR traffic arrival time coincides with the DRX on duration start time, the start time of the DRX on duration is calculated according to the foregoing formula and is 0, 17, 34, and 50, respectively, and the DRX cycle information is shown in fig. 5.

In the above example, with a non-integer period matching with the XR period, the RRC supports DRX non-integer period configuration, and the gNB sends the DRX non-integer period configuration to the UE to complete the DRX configuration. The scheme is simple and direct, the XR is consistent with the DRX period, the effect of terminal energy conservation is achieved, and the capacity of data transmission in an XR scene is improved.

The DRX adopts two schemes of integer period configuration and non-integer period configuration, and can adjust the DRX period configuration according to semi-static/dynamic signaling, so as to support the DRX period configuration suitable for XR service.

DRX integer period configuration is adopted, DRX period configuration in the existing RRC high-level signaling is not changed, offset required for estimating the starting time of the DRX period is imported through service features, specific adjustment can be adjusted according to conditions such as XR service QoS/QoE and network environment, configuration is more flexible and applicable to different network environments and service conditions, and the configuration can be expanded to different XR services or the optimization of DRX configuration is carried out by extracting service features through an AI model. According to the method and the device, smaller average receiving time delay can be realized according to flexible dynamic configuration, and balance between energy conservation and user experience is realized.

The DRX non-integer period configuration is adopted, the DRX non-integer period is supported by a standard high-level protocol to be modified, the high-level protocol is generally semi-static configuration, the protocol is required to be correspondingly modified according to the common non-integer period of XR service, and the scheme is simple to realize.

In the implementation of the present disclosure, the network side (e.g., the gNB) configures and adjusts the DRX parameter configuration of the UE according to the non-integer periodic characteristics of the XR service, the QoS/QoE requirements, the data volume to be transmitted in the buffer, the service model prediction result, and the like, so that the non-integer periodic characteristics of the XR service can be better adapted, the DRX energy saving efficiency is improved, and the XR service delay is reduced.
