Description

Discontinuous Reception (DRX) method, discontinuous reception device, electronic equipment and storage medium

Technical Field

The disclosure relates to the technical field of wireless communication, and in particular relates to a Discontinuous Reception (DRX) method, a device, an electronic apparatus and a storage medium.

Background

Augmented Reality (Augmented Reality, AR) and Virtual Reality (VR) are one of the important application scenarios/services in 5G, and will be fully evolved to augmented Reality (XR) in the 5G-Advanced and 6G ages.

3GPP is developing research work for XR services, and more than 20 companies propose that NR requires technical enhancement for XR new services. XR services have the requirements of high transmission rates, low latency and high reliability, which presents a significant challenge for existing NR networks. 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 support terminal realizes energy saving through discontinuous reception DRX, but the existing scheme can not well adapt to XR service, and transmission delay and energy saving effect are not ideal due to quasi-periodic characteristics of jitter. Therefore, how to enhance the existing discontinuous reception (C-DRX) in a connection state to better adapt to the requirements of XR novel services and reduce delay and terminal energy consumption is a technical problem to be solved at present.

It should be noted that the information disclosed in the above background section is only for enhancing understanding of the background of the present disclosure and thus may include information that does not constitute prior art known to those of ordinary skill in the art.

Embodiments of the present disclosure are described in detail below with reference to the attached drawings.

The discontinuous reception means that the terminal periodically stops monitoring the control channel at the base station side for a period of time so as to achieve the purpose of reducing the power consumption of the terminal. Discontinuous reception is largely divided into two types: discontinuous reception in an idle state and discontinuous reception in a connected state, wherein the discontinuous reception in the idle state is controlled by setting a fixed period, and the terminal monitors only one paging opportunity in each period; discontinuous reception in the connected state is mainly controlled by setting a Timer of parameters such as a DRX Cycle (DRX Cycle), a DRX wake-up phase (On Duration Timer), a DRX Inactivity Timer (Inactivity Timer), a DRX retransmission Timer (Retransmission Timer), and a DRX Activity Time (Activity Time).

The DRX sleep phase is defined as the time in the DRX cycle excluding the DRX wake-up phase or the period in the DRX cycle excluding the DRX active time.

Fig. 1 illustrates a DRX schematic diagram in an embodiment of the present disclosure, as shown in fig. 1, where a DRX cycle includes a DRX wakeup phase in which a terminal listens to and receives data of a physical downlink control channel PDCCH, and a DRX sleep phase in which the terminal stops listening to data of the physical downlink control channel PDCCH, so as to save power consumption of the terminal. The DRX wake-up stage is a period of time for which the terminal keeps awake after waking up from the DRX sleep state each time; the DRX inactivity time period is a time period which is continued after the terminal successfully demodulates the data of the PDCCH, and if the terminal does not successfully demodulate the data of the PDCCH, the terminal enters a DRX dormancy stage; the DRX retransmission time period is a duration period of receiving retransmission; the DRX Active Time (Active Time) is the total duration that the terminal listens to the PDCCH, and includes: a DRX wake-up phase, a DRX inactivity period, and a DRX retransmission period.

The current standard supports the use of DRX Command MAC CE and Long DRX Command MAC CE, stopping the DRX On duration and activity timers, allowing the terminal to quickly go to sleep or flexibly switch between a DRX Long Cycle (Long DRX Cycle) and a DRX Short Cycle (Short DRX Cycle). In this way the duration of the DRX wake-up phase can be reduced or prolonged, but the starting time of the DRX wake-up phase and the duration of the DRX cycle cannot be changed.

From the above, the DRX mechanism can enable the terminal to wake up and sleep periodically, and also can flexibly prolong the time for the terminal to monitor the PDCCH if necessary, so as to reduce the service delay, but the technology still has room for further optimization. Because in the actual application scenario, the terminal will not continuously send or receive data, for example, when the user is reading the cached web page with the mobile phone, interaction with the network is not needed, and if the terminal is still periodically awakened, unnecessary power consumption is additionally caused. Therefore, based on the original DRX mechanism, in order to optimize the power consumption of the terminal, the 3GPP proposes a DRX Adaptation in 5G, which is called DCP (DCI with CRC scrambled by PS-RNTI), and when the network side needs to perform uplink and downlink scheduling for a certain UE, a WUS (Wake-Up Signal) Signal (PDCCH carrying DCI Format 2_6) is sent to the UE, the UE detects the WUS Signal in a time window before the DRX wakeup stage, when the UE receives the WUS Signal, the UE detects the PDCCH in the DRX wakeup stage, and if the WUS Signal is not detected in the time window, the UE keeps a dormant state in the subsequent DRX wakeup stage, and does not perform PDCCH detection, so as to reduce the power consumption, thereby improving the battery service time.

It should be noted that if the network side indicates that the service of the DRX on-duration that needs to be closed does not match with the service of the terminal through WUS, the transmission of the service of the terminal may be affected. If the WUS is only associated with the short DRX and the period of the short DRX is configured to be relatively short, if the WUS is not received, that is, the UE is required to go to sleep in the short DRX, the UE may not go to sleep yet, which results in not achieving a better energy saving effect. Therefore, WUS generally only works for long DRX when both are configured.

It should be noted that, the WUS related configuration parameter is a DCP-Config-r16 carried by RRC Setup or RRC Reconfiguration and sent by the network side device to the terminal, the PS-RNTI is a newly added RNTI, which is fully called Power save-RNTI, and is used for performing CRC scrambling on the PDCCH sent to the UE, and it should be noted that, the terminal only monitors the PDCCH scrambled by the PS-RNTI in the dormant state.

Fig. 2 shows a schematic diagram of DRX adaptation based on DCP monitoring in the embodiment of the present disclosure, as shown in fig. 2, where the DCP monitoring is started by semi-static configuration of PS-offset, before DRX on-duration, and when the DCP is monitored to include Waka Up Signal (WUS), the PDCCH is detected at the next DRX on-duration, otherwise, the PDCCH is not detected at the next DRX on-duration.

Fig. 3 is a schematic diagram of a communication system architecture according to an embodiment of the disclosure, where, as shown in fig. 3, the communication system architecture includes a network side device 301 and a terminal 302; the network side device 301 sends signaling carrying DRX configuration information to the terminal 302, and after receiving the signaling from the base station 301, the terminal 302 configures and/or adjusts one of the following DRX parameter configurations of the terminal in a semi-static and/or dynamic manner: a DRX cycle, a DRX wake-up phase, a DRX inactivity timer, a DRX retransmission timer, and a DRX activity time.

Optionally, the terminal 302 in the embodiment of the present disclosure may also be referred to as a UE (User Equipment), and in a specific implementation, the terminal 302 may be a terminal side Device such as a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), a mobile internet Device (Mobile Internet Device, MID), a Wearable Device (webable Device), or a vehicle-mounted Device, which is not limited to a specific type of the terminal in the embodiment of the present disclosure.

Alternatively, the network-side device 301 in the embodiment of the present disclosure may be a base station, a relay, or an access point, or the like. The base station may be a 5G or later version base station (e.g., 5G NR NB, gNB, ng-eNB, en-gNB), or a base station in other communication systems (e.g., eNB (Evolutional Node B, evolved base station)), and it should be noted that the specific type of network side device is not limited in the embodiments of the present disclosure.

Those skilled in the art will appreciate that the number of terminals and network side devices in fig. 3 is merely illustrative, and any number of terminals and network side devices may be provided as desired. The embodiments of the present disclosure are not limited in this regard.

Firstly, in the embodiment of the disclosure, a discontinuous reception DRX method applied to a terminal is provided, and the method is applicable to, but not limited to, a method for discontinuous transmission of a new service of a 5G-Advanced/6G network, and adapts to new service characteristics through dynamic adaptive DRX configuration.

Fig. 4 shows a flowchart of a discontinuous reception DRX method applied to a terminal in an embodiment of the present disclosure, as shown in fig. 4, the discontinuous reception DRX method provided in the embodiment of the present disclosure includes the following steps:

step S402, the terminal receives signaling carrying DRX configuration information sent by the base station, where the DRX configuration information is used to configure and/or adjust one of the following DRX parameter configurations of the terminal in a semi-static and/or dynamic manner: a DRX cycle, a DRX wake-up phase, a DRX inactivity timer, a DRX retransmission timer, and a DRX activity time.

It should be noted that, in the embodiment of the present disclosure, the signaling carrying DRX configuration information is at least one of the following: downlink control information DCI signaling, medium access control element MAC CE signaling, radio resource control RRC signaling.

In some embodiments, the DRX configuration information may include the following parameters: DRX start offset.

It should be noted that, the DRX start offset in the embodiments of the present disclosure may be a DRX start-offset, which may also be referred to as DRX Offset indicator, DRX Shift, etc., and is used for performing the function of configuring or adjusting the DRX parameter configuration in the embodiments of the present disclosure.

In the embodiment of the disclosure, the DRX mode of the terminal can be adapted to XR service jitter characteristics by adjusting the DRX initial offset. In some embodiments, adjustment of the DRX start offset may be achieved by defining the DRX On duration/active-time or the start time of the DRX cycle. In the specific implementation, the base station dynamically indicates the DRX initial offset through the signaling so as to adapt to the XR service jitter characteristics, improve the matching degree of the DRX and XR multi-stream jitter service characteristics, reduce the XR service processing time delay and improve the energy-saving efficiency.

In some embodiments, the signaling carrying DRX configuration information sent by the base station is monitored when the terminal is at least one of: DRX wake-up phase, DRX active time, DRX sleep phase. When the terminal is in On duration/active-time or DRX dormant stage, the starting moment adjusting parameter is monitored, and the base station dynamically indicates DRX start-offset through DCI or MAC CE. For example, when On duration/active-time indication, the DCI format1_0/1_1 is scheduled with downlink data to increase indication or newly define DCI format; at the DRX sleep stage indication, the DCI format 2_6 based on the original DCP transmission WUS (Wake Up Signal) is additionally indicated or newly defined. Sending the indication at different stages may have different effects and advantages. And in the DRX wake-up stage and the active time, the terminal needs to monitor the PDCCH, and the DCI or the MAC CE is sent to instruct at the moment without additionally increasing the monitoring workload of the terminal, thereby being beneficial to saving the energy consumption of the terminal. In addition, when the sleep period is longer, the monitoring in the sleep period has important significance for the adjustment of the DRX configuration, the performance influence caused by burst service or burst jitter can be better processed, and the QoS of the service is ensured.

In specific implementation, a new indication and a DRX Start Offset field may be added in the downlink control information DCI format 1_0/1_1/1_2, and the DRX Start Offset may be added based on the DCI format 2_6 sent WUS (Wake Up Signal) by the original DCP, or the indication may be performed by using an existing field in the DCI, for example: when the RV field is some predefined value (00), the HARQ Process Number field indicates information for DRX Start Offset, which may be an absolute value, a number of slots and/or symbols indicating a specific Offset, or an index value. The index value may be indexed from the above table/array/set to the required DRX StartOffset value using a standard predefined DRX StartOffset table/array/set. The reuse of the newly added field of the existing DCI format for indication has a certain degree of flexibility, and meanwhile, the blind detection complexity is increased by a small amount, and the method belongs to a compromise scheme. Reuse of existing DCI format reuse existing field can not newly increase/save DCI load size of control channel, flexibility is lowest, but blind detection complexity is not additionally increased, and realizability is stronger. The DCI format is newly defined, wherein the DRX StartOffset parameter is defined, the mode has the highest flexibility, the new format is supported when the search space configuration is needed, and different blind detection numbers can be affected under different configuration conditions.

In some embodiments, the DRX configuration information is set by the base station according to relevant parameters, including at least one of: UE traffic side information (UE Assistance Information), traffic characteristics, quality of service QoS, quality of experience QoE, traffic flows, buffer amount of data to be transmitted, packet size, traffic model prediction results.

It should be noted that, the UE service assistance information is information sent by the UE to the base station and/or the core network, where the UE may include a DRX Start Offset configuration value that is recommended to be configured to the network side according to the current network and service (e.g., XR multi-stream video service) situation and the detected jitter characteristic, for example: the configuration values and the time ranges are recommended.

In the embodiment of the disclosure, the service characteristics, the quality of service QoS, the quality of experience QoE, the traffic flow, the data volume to be transmitted in the buffer, the data packet size and the like according to which the base station sets the DRX configuration information may be related parameters obtained by the base station from detection and analysis of the related information by the terminal, the core network, the network manager or the base station itself.

The service model prediction result may be a prediction result of future service obtained by the base station from the terminal or the core network or the network manager, where the prediction may be analyzed and predicted by using an artificial intelligence or machine learning model to form a recommended configuration value of the DRX configuration information. The network manager/base station may set a periodic service prediction detection policy and trigger conditions for DRX Start Offset configuration/signaling transmission (for example, jitter prediction is greater than a threshold value M, and a QoS guarantee threshold Q), and when the network manager/base station performs periodic detection and the trigger conditions are met, for example, the service jitter prediction is greater than the threshold value M and/or the QoS guarantee threshold is lower than Q, the network manager/base station triggers DRX Start Offset transmission, that is, the network may dynamically and adaptively complete adjustment/optimization of DRX information configuration and transmission of DRX Start Offset according to the configuration. The DRX configuration is better suitable for transmission of novel services such as XR, so that the energy consumption of a terminal and a network is saved, and the QoS/QoE of a user is ensured.

When XR service is multi-stream and different streams have different time delay jitter conditions due to different blocking conditions of a transmission network through service model prediction analysis, UE sends UE auxiliary information to a base station to indicate different DRX Start Offset configuration recommended values for two streams, the recommended values are used for adjusting a DRX window by using the DRX Start Offset value of a first stream when the network transmits the first stream, and the DRX window is adjusted by using the DRX Start Offset value of a second stream when the network transmits the second stream.

When XR service is single-stream and network transmission condition is good, network side carries out statistic analysis to XR service transmission confirmation condition, and at present, service transmission jitter condition is not serious, network does not send DRX Start Offset configuration adjustment.

When more data to be transmitted or more data packets to be transmitted in the buffer area are needed, the network side confirms that the current QoS guarantee condition of the terminal is not good, the network sends DRX Start Offset configuration, the DRX wake-up window is advanced and/or the DRX window duration is prolonged, XR service data about to be overtime is transmitted in advance, and QoS/QoE of a user is guaranteed.

In the above case, the DRX Start Offset may be adjusted, which also includes the adjustment parameter X, and also includes detection/prediction and adjustment and configuration of the recommended value of the DRX cycle/DRX wake-up phase.

In some embodiments, the terminal performs at least one of the following operations on the DRX parameter configuration according to the DRX configuration information carried by the signaling: defining the starting time of the next DRX wake-up stage and/or the DRX cycle after the current DRX cycle and/or the DRX wake-up stage to be advanced or delayed, so that the starting time of the subsequent DRX wake-up stage and/or the DRX cycle is changed; defining X DRX wake-up phases and/or start moments of the DRX cycles after the current DRX cycle and/or the DRX wake-up phases to advance or delay; and defining to adjust the last DRX cycle and/or the last DRX wake-up stage in the X DRX cycles and/or the last DRX wake-up stage so that the starting time of the subsequent DRX wake-up stage and/or the last DRX cycle in the X DRX cycles and/or the last DRX wake-up stage is not changed.

For example: DRX Start offset=01 means that the next DRX wakeup phase is advanced by 0.5ms.

In some embodiments, the following rules may be defined: when the DRX Start Offset is positive, representing that the DRX wake-up phase is advanced, the cycle length of the DRX cycle is increased by the DRX Start Offset; when the DRX Start Offset is negative, the cycle length of the DRX cycle is reduced by the DRX Start Offset.

In some embodiments, the base station transmits the parameter value of parameter X to the terminal by any one of: dynamically indicating the parameter value of the parameter X through DRX configuration information; semi-static configuration is carried out on the parameter value of the parameter X through RRC signaling; the parameter values of parameter X are predefined by criteria.

For example: x=1 means configuring the following 1 DRX cycle and/or DRX wake-up phase; x=2 means configuring the following 2 DRX cycles and/or DRX wake-up phases; x=3 means configuring the following 3 DRX cycles and/or DRX wake-up phases; x=4 means that the following 4 DRX cycles and/or DRX wake-up phases are configured. For example: a value not defining X may be regarded as x=1 by default.

Suppose mode 1 indicates that the starting time of the next On duration/DRX Cycle is advanced or delayed by DRX start-offset, and the time points at which the following DRX cycles and On durations start are also adjusted simultaneously; the mode 2 is that starting moments of the following X On duration/DRX cycles are advanced or delayed through DRX start-offset indication, X is dynamically indicated through the signaling, semi-static configuration is carried out through RRC signaling, or the Cycle length of the last DRX Cycle of the X cycles is correspondingly adjusted through standard predefining, the starting time points of the following DRX cycles and the On duration are not influenced, the existing DCI format1_0/1_1/2_6 can be utilized for notification, the realizability is strong, the mode 1 notification mode is simple, the mode 2 can be better adapted to service jitter characteristics, and the service characteristics can be better matched. Fig. 5 shows the DRX adjustment of implementation 1 by monitoring DRX start-offset during the DRX wake-up phase; fig. 6 shows the DRX adjustment of implementation 2 by monitoring DRX start-offset during the DRX wake-up phase; fig. 7 shows the DRX adjustment of implementation 1 by monitoring DRX start-offset during the DRX sleep phase; fig. 8 shows the DRX adjustment of implementation 2 by monitoring DRX start-offset during the DRX sleep phase.

In some embodiments, the base station obtains service characteristic information according to terminal service auxiliary information indication and/or network side data acquisition analysis. In specific implementation, the base station can adaptively adjust the DRX start offset and/or the parameter value of the parameter X according to the obtained service characteristic information.

In the specific implementation, the base station dynamically and adaptively adjusts the initial moment adjustment parameter configuration according to the UE service auxiliary information and/or the service characteristic information acquired by the network side data acquisition and analysis, and can carry out RAN side service characteristic importing through application layer service requirements, data acquisition and artificial intelligence, so that network service cooperative transmission is enabled, the service requirements are better met, time delay is reduced, and energy efficiency is improved.
