Technical Field

The present disclosure relates to the field of communication technology, and in particular, to a discontinuous transmission DRX method, a terminal, a network device, an electronic device, a computer readable storage medium, and a computer program product.

Background

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

In the related art, research of XR simulation modeling is carried out, and the subsequent NR is proposed to be required to be subjected to technical enhancement aiming at XR novel 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. XR devices will have more limitations 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.

Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art.

In the description of the present disclosure, unless otherwise indicated, "/" means "or" and, for example, a/B may mean a or B. "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. Furthermore, "at least one" means one or more, and "a plurality" means two or more. The terms "first," "second," and the like do not limit the number and order of execution, and the terms "first," "second," and the like do not necessarily differ.

The techniques described herein are not limited to long term evolution (Long Term Evolution, LTE)/LTE evolution (LTE-Advanced, LTE-a) systems and may also be used in various communication systems such as code division multiple access (Code Division Multiple Access, CDMA), time division multiple access (Time Division Multiple Access, TDMA), frequency division multiple access (Frequency Division Multiple Access, FDMA), orthogonal frequency division multiple access (Orthogonal Frequency Division Multiple Access, OFDMA), single-carrier frequency division multiple access (Single-carrier Frequency-Division Multiple Access, SC-FDMA), and other systems. The terms "system" and "network" are often used interchangeably. The techniques described herein may be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies. However, the following description describes an NR (New Radio) system for purposes of example, and NR terminology is used in much of the following description, although these techniques may also be applied to applications other than NR system applications.

A communication system to which embodiments of the present disclosure are applicable may include a terminal and a network device.

The terminal may also be referred to as a terminal Device or a User Equipment (UE), and the terminal 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 (weardable Device), or a vehicle-mounted Device, which is not limited to a specific type of the terminal in the embodiments of the present disclosure.

The network device may be a base station or a core network, where the base station may be a 5G (5 Generation, fifth Generation) mobile communication system and later base stations (e.g., a gNB, a 5G NR NB, etc.), or base stations in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), where the base station may be referred to as a node B, an evolved node B, an access point, a base transceiver station (Base Transceiver Station, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, and the base station is not limited to a specific technology vocabulary, and the base station in the embodiment of the disclosure only uses the base station in the NR system as an example, but is not limited to a specific type of the base station.

The base stations may communicate with the terminals under the control of a base station controller, which may be part of the core network or some base stations in various examples. Some base stations may communicate control information or user data with the core network over a backhaul. In some examples, some of these base stations may communicate with each other directly or indirectly over a backhaul link, which may be a wired or wireless communication link. A communication system may support operation on multiple carriers (waveform signals of different frequencies). A multicarrier transmitter may transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multicarrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base station may communicate wirelessly with the terminal via one or more access point antennas. Each base station may provide communication coverage for a respective corresponding coverage area. The coverage area of an access point may be partitioned into sectors that form only a portion of that coverage area. The communication system may include different types of base stations (e.g., macro base stations, micro base stations, or pico base stations). The base station may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations, including coverage areas of the same or different types of base stations, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks, may overlap.

The communication links in the communication system may include an Uplink for carrying Uplink (UL) transmissions (e.g., from a terminal to a network device) or a Downlink for carrying Downlink (DL) transmissions (e.g., from a network device to a terminal). UL transmissions may also be referred to as reverse link transmissions, while DL transmissions may also be referred to as forward link transmissions.

Fig. 1 schematically illustrates a schematic diagram of a DRX cycle according to an embodiment of the present disclosure.

Up to 2 sets of DRX configurations can be configured for a cell in NR through RRC (Radio Resource Control ) signaling.

As shown in fig. 1, the DRX configuration information may include on Duration (DRX wake-up time), DRX Cycle (DRX Cycle), inactivity timer (retransmission timer), and other parameters, and each UE uses a set of DRX configurations.

on Duration: the UE remains awake each time from DRX wake-up, during which the UE monitors the PDCCH (Physical Downlink Control Channel ).

DRX Cycle: consists of a DRX wake-up time and a DRX sleep time (Opportunity for DRX) 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: duration for receiving retransmission

active-time: the total Duration that the UE listens to the PDCCH may include the time of "on Duration" of the DRX cycle, the time of "inactivity-timer" and the time of "retransmission-timer".

In the related art, each UE supports at most two sets of DRX parameters, and each set of DRX parameters includes different on Duration and long and short periods, but only one set of DRX parameters can be used by the UE.

The NR supports the DRX terminal energy saving technology, but the scheme provided in the related technology cannot well adapt to the non-integer period of the XR service and the characteristic of variable packet size, and adopting fixed and uniform DRX configuration parameters, such as on Duration, for different data packet sizes may cause transmission delay, and the energy saving effect is also not ideal.

The characteristic of variable packet size of the XR service means that in the XR service, a data packet sent by a terminal to a base station is sometimes large and sometimes small, the XR service can generally comprise video/image stream, audio stream and the like, so that the data packets are different in size, and when the data packet is large, the original on Duration can be prolonged by adopting the method provided by the embodiment of the disclosure; when the data packet is small, the original on Duration can be kept unchanged; or, when the data packet is large, the original on Duration is kept unchanged; when the data packet is small, the original on Duration is shortened, so that the transmission delay can be reduced, or a better energy-saving effect can be achieved.

In the embodiment of the disclosure, a distinction may also be made between frames (frames) in a transmitted data packet, for example, whether an I-frame (Intra-coded Picture) or a P-frame (Predictive-coded Picture), where the I-frame is relatively large and more important, so that the time length requirement for the received On Duration may be different, the original On Duration may be extended for the I-frame, the original On Duration may be kept unchanged for the P-frame, or the original On Duration may be shortened, thereby reducing the transmission delay, or achieving a better energy saving effect.

The characteristic of XR traffic non-integer period means that the XR traffic generation data traffic period is non-integer, i.e. fractional. The DRX Cycle needs to be configured in the DRX configuration of the related standard, and the existing minimum DRX Cycle is supported to 1/32ms; XR traffic in the discussion, simulation modeling considers DRX cycles of 1/60ms and 1/120 ms.

As shown in fig. 2, assuming that DRX cycle=8ms, on duration=2ms, a service period of 8.33ms, and a rate of 120FPS (Frames Per Second, transmission frames per second), it can be seen from fig. 2 that the characteristic of the XR service non-integer period may cause the on Duration in the DRX Cycle and the XR service (i.e., one frame (a frame) in fig. 2) to come slowly, so that the reception of the downlink data packet cannot be performed, and the on Duration needs to be waited for the next DRX Cycle, which may prolong the reception time, resulting in undesirable transmission delay and energy saving effects.

Therefore, enhancement is needed for the existing connection state discontinuous transmission C-DRX (Connected mode DRX) to better adapt to the requirement of XR novel service, and delay and terminal energy consumption are reduced.

It should be noted that, although the XR service is taken as an example in the following embodiments, the "service" mentioned in the embodiments of the present disclosure is not limited to the XR service, and may be any service that needs to reduce energy consumption.

In the embodiments of the present disclosure, XR traffic flows may be related to video stream codecs selected for use by an application service provider providing XR services, where the flows may be single, dual, or multi-flows, such as the common codec mode MPEG (Moving Picture Experts Group, dynamic picture experts group) having several versions whose transmissions are divided into I frames and P frames, which may be considered dual-flow.

In the embodiment of the disclosure, DRX discontinuous reception mainly controls UE to detect DL PDCCH in discontinuous time, and is generally decoupled from uplink, where the amount of data to be transmitted in a buffer zone of a base station refers to downlink data to be sent to UE by the base station, and may also consider uplink buffer zone, XR service uplink and downlink have linkage characteristics, and after uplink sends certain control operation information, downlink has data to be received by UE.

In the embodiment of the disclosure, the service model prediction result may be a result obtained by predicting a service model, for example, an XR service model, which is one of the data generation models. The data generation model includes, but is not limited to, the following: AI/ML model, XR business model, calculation formula, etc. The data generation model may be used to generate DRX-related configuration parameters, such as multiple wake-up times and/or multiple DRX cycles and/or multiple inactivity timers and/or multiple retransmission timers.

In an embodiment of the present disclosure, the service model prediction result may include: XR traffic flow, packet size, period and jitter characteristics, etc., i.e., predictions of future XR traffic specific characteristics. The above features may be estimated by the network device implementation algorithm based on current and/or historical XR service data or may be obtained from an XR service application server/service provider.

The base station semi-statically and/or dynamically configures and/or adjusts the DRX parameter configuration of the UE of the current cell by signaling (such as RRC, MAC CE, DCI) according to the related parameters, DRX on Duration time and the like.

For example, if the current XR service is dual stream (video stream + audio stream), a dual cycle DRX parameter configuration may be configured (method 2 described below).

For another example, if the current XR service single flow is divided into two frame types, the I frame data packet is larger, and the QoS requirement is high; p frame is a number of packets sent following I frame, for example: the 8 data packets are smaller and the QoS requirements are relatively low. The On Duration window may be extended when an I frame packet needs to be received, and the corresponding I frame packet may be received using a longer time window due to the larger packet and high QoS requirements (e.g., a lower modulation and coding scheme and more retransmissions are required for high reliability) (method 1 described below).

For another example, the buffer area at the base station has more XR service data to be sent to a certain UE, the transmission cannot be completed in the current On Duration window, and the receiving time delay is larger, so that the base station adjusts the DRX parameter configuration, prolongs the On Duration time, sends out the buffered XR service data, and satisfies the QoS requirement of the XR service, otherwise, packet loss is easily caused by overlarge time delay.

For another example, when XR service video definition is adjusted, the standard definition is adjusted to a blue light mode, and an audio/video stream encoding and decoding mode is adopted, so that the size/stream number of a data packet predicted by a service model is changed, the DRX configuration is changed from a past single stream (method 1) to a dual-stream dual-cycle DRX parameter (method 2) configuration; or the period of the dual cycle DRX parameter configuration and parameters such as on Duration are changed to adapt to the dynamic change of XR service.

For another example, XR service has a non-integer periodic characteristic, the current network load is higher, and when the data generation model (AI/ML model, service model, etc.) predicts that the next XR data packet arrives, the AI/ML model gives that the current network load is higher and the QoS requirement of the XR service cannot be met; or the service model predicts the arrival time and the size of the next data packet, the base station implementation algorithm predicts that the delay is larger due to the fact that the base station implementation algorithm is staggered with the current DRX window, the On Duration configuration is adjusted, and the current On Duration window is prolonged until the data packet is received.

Method 1 is described as follows: the on Duration time is prolonged.

At the current DRX on Duration, the UE detects that the first signaling, e.g. MAC CE or DCI, contains at least one of on Duration configuration, active range configuration (timer or number of cycles, if the active range configures the timer, it is called DRX parameter active range timer; if the active range configures the number of cycles, it is called DRX parameter active range cycle), as DRX configuration information, one of the following operations is performed:

operation option 1: and the UE adjusts the current DRX cycle/one DRX cycle after the current DRX cycle/a plurality of (more than or equal to 2) DRX cycles/on Duration time of all DRX cycles according to the DRX configuration information, and when the on Duration time of all DRX cycles is not adjusted, the original on Duration configuration is restored.

For example: if the DRX configuration information contains only on Duration configuration, the UE adjusts the on Duration of the current DRX cycle, whether the on Duration of one DRX cycle after the current DRX cycle, whether the on Duration of several DRX cycles after the current DRX cycle, or the on Duration of all DRX cycles may be standard fixed, i.e. the standard defines which on Duration of which DRX cycle/cycles to adjust by default when receiving an on Duration configuration only.

For another example: it may be defined by the standard that if the active range period of the DRX parameter received by the terminal through the first signaling is 2 DRX periods after the current DRX period, the original on Duration length of the 2 DRX periods after the current DRX period is twice as long as the original on Duration length of the 2 DRX periods after the current DRX period is pre-agreed.

For example, if the UE has several data packets to send in the buffer, the base station scheduling algorithm expects to need to adjust the on Duration within 5ms to finish transmitting before the data timeout according to the XR service QoS requirement.

Operation option 2: and the UE starts a DRX parameter acting range timer according to the DRX configuration information, if the DRX parameter acting range timer exceeds a configuration threshold before overtime and/or the number of PDCCHs received by the UE/the size of PDSCH data packets and the like, according to network equipment pre-configuration or standard definition or signaling configuration, the current DRX cycle/the on Duration time of a plurality of DRX cycles/all DRX cycles after the current DRX cycle is adjusted, and when the on Duration time of all DRX cycles is not adjusted, the original on Duration configuration is restored.

For example, if the UE receives a DRX parameter coverage timer, such as a 5ms timer, then the on Duration in the 5ms timer is adjusted.

For another example, when the UE receives the DRX parameter coverage timer, the base station further configures a threshold (configuration threshold) for the number of PDCCHs/PDSCH packet size received by the UE, for example, PDSCH data received by the terminal exceeds 5Mbits within 5ms, and the terminal resumes the original on Duration. By configuring the threshold, the extended on Duration time can be more limited, mainly for avoiding excessive extension on Duration, and enough transmission is needed, so that better energy saving can be achieved.

The DRX configuration in the standard contains many timers, the DRX parameter scope timer is not an inactivity timer and a retransmission timer.

In the embodiment of the disclosure, the scope of action is configured, for example, when the UE detects the first signaling to notify that the on Duration is to be prolonged, for example, to be prolonged by 0.25ms, and that the prolongation is to act on the current on Duration window, or that the next 5 on Duration windows are each prolonged by 0.25ms, a timer or the number of periods is needed to notify the UE, and that the on Duration window is prolonged, or that the on Duration window that acts within 10ms is prolonged, or that the on Duration window of 5 periods in the future is prolonged.

In the embodiment of the present disclosure, the number of periods in the active range configuration refers to how many DRX periods the first signaling, for example, the MAC CE or the DCI, specifies that the on Duration carried by the DRX configuration information (which is not limited to direct carrying of the DRX configuration information, and may also be obtained by the terminal itself through the data generation model) may be applicable to.

Although the method 1 is exemplified by adjusting the on Duration to extend the on Duration, the present disclosure is not limited thereto, and the on Duration may be shortened. The length of the extension or the length of the shortening can be set according to actual requirements, and the disclosure is not limited to this.

The method 1 may be understood that the base station originally configures an original on Duration for the UE (for example, by RRC signaling configuration, a change period is longer, and data is semi-statically configured), but after the UE receives the original on Duration configured by the base station, the UE may not execute according to the original on Duration configured by the base station originally using RRC signaling, and the base station may dynamically change a specific value of the DRX on Duration by using MAC CE or DCI signaling that is more dynamic and flexible than RRC. That is, the configuration of the on Duration (including the original on Duration and the new on Duration) is configured by the base station to the UE, and the UE performs the configuration, except that the configuration includes several layers, the on Duration that is more stable and semi-static for a long period of time can be configured by the RRC, and the on Duration that is suitable for the dynamic configuration can be configured by the RRC and/or MAC CE and/or DCI.

The method 1 can adjust partial or all DRX configuration through the semi-static/dynamic adjustment of MAC CE/DCI on Duration, can limit the adjustment range through the number of timers or configuration periods, can flexibly combine various signaling configuration methods, and has stronger network realizability.

Method 2: configuring the bi-period/multi-period/variable length sequence on Duration and/or DRX Cycle may be configured by one of the following ways:

configuration mode 1: the on Duration parameter sets { d1, d2, …, di } and/or the DRX Cycle parameter sets { c1, c2, …, cj } are configured by a first signaling (e.g., RRC, MAC CE, DCI), where i and j are integers greater than 1, e.g., i, j=2, 3 …, e.g.: the Duration of on Duration is d1, d2, … di, respectively, and the corresponding DRX Cycle Duration is c1, c2, …, cj, respectively, alternate.

The dual Cycle on Duration is that i is 2, the dual Cycle DRX Cycle is that j is 2, the multi-Cycle on Duration is that i is greater than 2, the multi-Cycle DRX Cycle is that j is greater than 2, the variable length sequence on Duration is that i can be flexibly set, and the variable length sequence DRX Cycle is that j can be flexibly set.

For example, j=1, i=2, the on Duration of the terminal alternately adopts d1 and d2, and the DRX Cycle is c1. Alternating means that the first DRX cycle that is adjusted employs d1 and c1; the second DRX period to be adjusted adopts d2 and c1, and the 3 rd DRX period to be adjusted adopts d1 and c1; the fourth DRX cycle that is adjusted uses d2 and c1; ….

For another example, i=j, then alternating means that the adjusted first DRX cycle employs d1 and c1; the second DRX cycle that is adjusted uses d2 and c2, and the i-th DRX cycle that is adjusted … uses di and ci; then the i+1th DRX cycle being adjusted employs d1 and c1; … and so on.

Configuration mode 2: the configuration sequences of on Duration and DRX Cycle are obtained by the base station side and the terminal side adopting the same data generation model (such as AI/ML model, XR service model, calculation formula and the like) defined by a standard/network and the base station side to carry out the configuration of the relevant parameters of the model.

The method 2 is used for configuring the double-period/multi-period/variable-length sequence on Duration and/or DRX Cycle, an on Duration parameter set and/or a DRX Cycle parameter set can be configured through a first signaling, different parameters in the parameter set are used alternately, the scheme and the standard definition are simple, and the realizability is strong.

I.e. the base station side and the terminal side have previously negotiated which data generation model to use, e.g. both to use XR service models, by means of standard definitions or network predefined means. The base station then sends parameters configuring the XR service model to the UE, the base station and the UE generate (obtain) on Duration parameter sets { d1, d2, …, di } and/or DRX Cycle parameter sets { c1, c2, …, cj } using the same XR service model and parameter configuration, respectively known as configuration sequences on Duration and DRX Cycle, and both the base station and the UE perform DRX according to the generated configuration sequences.

For another example, the terminal and the base station set the same calculation formula, such as c1=5 ms, and when j is an odd number, dj=0.125 ms; when j is even, dj=0.25 ms.

And the UE monitors the downlink PDCCH in the on Duration of the wake-up time, and enters a sleep period after the standard defined wake-up time is ended, so that the energy consumption is saved.

In addition, the base station side and the terminal side can adopt the same data generation model defined by standards/predefined by a network and the base station side to carry out the relevant parameter configuration of the model, and the service characteristics of the RAN (wireless access network ) side can be imported by introducing a calculation formula/service model and artificial intelligence, so that the network service cooperative transmission can be realized, the service requirement can be better met, and the energy consumption can be reduced. In the method 2, a calculation formula, an XR service model or an AI/ML model can be used to generate a corresponding parameter set of DRX configuration, in the related art, when the network configures DRX, it is not known what service the UE has at all, and the configuration result is that DRX is not matched with the actual service requirement of the UE, the UE is dormant when receiving, the UE wakes up when no service is available, and the PDCCH power consumption is detected in that blind.

The introduction of the AI/ML model and the service model has the effect equivalent to that of a base station which has no additional service information interaction with a terminal, the requirement of the UE is known through the introduction of the data generation model, and the special DRX configuration of different UEs is configured according to the requirement of the UE.

For example, the user A plays XR games to 9 points every night through the UE, the user A only needs to play games with a single stream standard definition, the user B plays games with 10 points to 11 points every day through the UE, blue light double-current is used, the other game place for providing XR entertainment is busy only on weekends, different needs are met, the network side can configure an energy-saving DRX mode according to the needs of the UE through a data generation model, so that a base station/access network RAN can combine the service needs and network capacity to transmit downlink data, and the energy consumption is reduced while the service needs are met.

In the prior art, a specific scheme for discontinuous transmission (DRX) optimization according to novel services such as XR and the like is not available. According to the method provided by the embodiment of the disclosure, on one hand, the base station semi-statically or dynamically configures and/or adjusts DRX parameter configuration of the UE according to XR service characteristics and QoS/QoE requirements, data volume to be transmitted in a buffer, XR data packet size change, service model prediction results and the like, so that the characteristic of variable packet size of XR service can be better adapted, the traditional DRX energy-saving efficiency is improved, and XR service time delay is reduced. On the other hand, by introducing an artificial intelligence/service model/calculation formula, the service characteristics of the UE are more considered when the network configures the DRX parameter, and in the most ideal case, the UE is in the awake period of DRX only when the service needs to be received, and other times are dormant, so that the maximum energy saving is realized. The method can be suitable for discontinuous transmission DRX in an XR service RRC connection state.

In the embodiment of the disclosure, the terminal may be configured with multiple sets of DRX parameters, and when the terminal is in different states or performs different services, the DRX parameters may be changed to adapt to performance requirements of different states or different services. The above embodiments are illustrated with two parameters, on Duration and DRX Cycle, in a DRX parameter configuration, which determine the time for the UE to wake up and sleep. A terminal in the related art may have multiple configurations, but only one configuration (i.e. corresponding to one on Duration and DRX Cycle parameter configuration) can be selected for use by the UE, that is, only one set of DRX parameters is active when running the DRX procedure although multiple sets of DRX parameters are configured, and in order to adapt to the XR service characteristic, the present application supports different on Duration and DRX Cycle configurations in the same DRX Cycle.

In the future, a novel service XR exists, and has high requirements on service experience, high speed, low delay, high reliability and other performances; XR traffic has characteristics of multi-stream variable packet sizes, such as: the ultra-high definition video packet-size is large, and then the voice packet-size is small, so that the energy consumption is critical to the XR device as described in the background, so that in order to save energy well, in the set of DRX parameter configuration, the on Duration is preferably not always equal to a value, and the model of XR service can be preferably adapted to the characteristic that the model is sometimes large and sometimes small.
