Description

Technical Field

[0001] The present application relates to the field of communications, and more specifically, to a communication method and a communication device. Background Art

[0002] With the development of communications, the fifth generation (5G) communication system has gradually infiltrated some multimedia services with strong real-time performance and large data capacity requirements, such as video transmission, cloud gaming (CG) and extended reality (XR).

[0003] The generation and arrival of data packets of the above multimedia services are not continuous. On the terminal side, the terminal can listen to the downlink control information (DCI) of the network device in each time slot and receive uplink authorization or downlink data according to the DCI. However, the terminal listens to the DCI in each time slot, which increases the power consumption of the terminal. In order to reduce the power consumption of the terminal, a discontinuous reception (DRX) mechanism is introduced in 5G communication. The DRX mechanism configures a DRX cycle for the terminal. In each DRX cycle, a wake-up (on duration) period and a sleep period are configured. During the wake-up period, the terminal can monitor and receive DCI. During other periods, the terminal has the opportunity to enter a sleep state to reduce power consumption.

[0004] For the above multimedia services, the arrival period of data of different services may be different (for example, the frame rate of the video service may be 60 frames per second (FPS), that is, the arrival period of the video frame is 16.67ms, and the arrival period of the audio data of the audio service may be 10ms). Therefore, how to configure the DRX cycle for the data of different services to save signaling overhead is a problem that needs to be considered. Summary of the invention

[0056] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0057] Figure 1 1 is a schematic diagram of the architecture of a communication system 10 applicable to the present application.

[0058] Figure 1 This is a simplified schematic diagram for ease of understanding only. The communication system 10 may also include other RAN nodes or other terminal devices. Figure 1 Not shown.

[0059] The above-mentioned communication system architecture applied to the embodiment of the present application is only an example, and the communication system architecture applicable to the embodiment of the present application is not limited to this. Any communication system architecture that can realize the functions of the above-mentioned devices is applicable to the embodiment of the present application.

[0060] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, universal mobile telecommunication system (UMTS), fifth generation (5G) system or new radio (NR) or other evolved communication systems. The technical solutions of the embodiments of the present application can also be applied to future communication systems, such as the sixth generation mobile communication system, etc., which are not limited in the present application.

[0061] The technical solution of the embodiment of the present application can also be applied to machine type communication (MTC), long term evolution-machine (LTE-M), device-to-device (D2D) network, machine-to-machine (M2M) network, Internet of Things (IoT) network or other networks. Among them, the IoT network can include, for example, the Internet of Vehicles. The communication methods in the Internet of Vehicles system are collectively referred to as vehicle to other devices (vehicle to X, V2X, X can represent anything). For example, the V2X may include: vehicle to vehicle (V2V) communication, vehicle to infrastructure (V2I) communication, vehicle to pedestrian (V2P) communication or vehicle to network (V2N) communication, etc.

[0062] The terminal device in the embodiment of the present application may be a wireless terminal capable of receiving RAN node scheduling and indication information. The terminal device may be a device that provides voice and / or data connectivity to a user, or a handheld device with a wireless connection function, or other processing devices connected to a wireless modem.

[0063] Terminal equipment may also be referred to as terminal, access terminal, user unit, user equipment (UE), user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, wireless communication device, user agent or user device. Terminal equipment is a device that includes wireless communication function (providing voice / data connectivity to users). For example, a handheld device with wireless connection function, or a vehicle-mounted device, etc. The terminal in the embodiments of the present application can be a mobile phone, a tablet computer (pad), a computer with wireless transceiver function, a train, an airplane, a mobile Internet device (MID), a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control (such as a robot, etc.), a wireless terminal in the Internet of Vehicles (such as an on-board device, a whole vehicle device, an on-board module, a vehicle, etc.), a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart city, a wireless terminal in smart home, a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a wireless telephone, ... digital assistant, PDA), handheld devices with wireless communication functions, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, terminals in 5G networks or terminals in future evolution networks, etc. It can be understood that all or part of the functions of the terminal device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform).

[0064] Among them, wearable devices can also be called wearable smart devices, which are a general term for the intelligent design and development of wearable devices for daily wear using wearable technology, such as glasses, gloves, watches, clothing and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also realize powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-sized, and independent of smartphones to achieve complete or partial functions, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0065] The RAN node in the embodiment of the present application may also be sometimes referred to as an access network device, a network device, a RAN entity or an access node, etc., which constitutes a part of the communication system to help the terminal device achieve wireless access. The multiple RAN nodes in the communication system 10 may be nodes of the same type or nodes of different types. In some scenarios, the roles of the RAN node and the terminal device are relative, for example, Figure 1 The network element 120i may be a helicopter or a drone, which may be configured as a mobile base station. For the terminal devices 120j that access the RAN 100 through the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal device. The RAN node 110 and the terminal device 120 are sometimes referred to as communication devices, for example Figure 1 The network elements 110a and 110b may be understood as communication devices having base station functions, and the network elements 120a-120j may be understood as communication devices having terminal functions.

[0066] In one possible scenario, a RAN node may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node may be a macro base station (e.g. Figure 1 110a in), micro base stations or indoor stations (such as Figure 1110b in the present application), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node may also be a server, a wearable device, a vehicle or an on-board device, etc. For example, the access network device in the V2X technology may be a road side unit (RSU). All or part of the functions of the RAN node in the present application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform). The RAN node in the present application may also be a logical node, a logical module or software that can implement all or part of the functions of the RAN node.

[0067] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU) or a remote radio head (RRH).

[0068] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in an open radio access network (O-RAN) system, CU may also be referred to as an open-central unit (O-CU); DU may also be referred to as an open-distributed unit (O-DU); CU-CP may also be referred to as O-CU-CP, CU-UP may also be referred to as O-CU-UP, and RU may also be referred to as O-RU. For the convenience of description, this application takes CU, CU-CP, CU-UP, DU and RU as examples for description. Any of the CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0069] With the continuous development of 5G communication systems, data transmission latency continues to decrease and transmission capacity is increasing. Some multimedia services with strong real-time requirements and large data capacity requirements are gradually infiltrating 5G communication systems, such as video transmission, cloud gaming (CG) and extended reality (XR), among which XR can include virtual reality (VR) and augmented reality (AR).

[0070] In the above multimedia services, the terminal device can be a smartphone, head mounted display (HMD) or smart glasses (such as VR glasses, AR glasses), etc. Unlike smartphones, head mounted displays and smart glasses need to consider the power consumption and battery life of the device more. In particular, smart glasses have a small size, similar to prescription glasses, and are expected to be worn for a long time, so the control requirements for power consumption are higher.

[0071] For XR transmission services and video transmission services, their service models are usually based on frame rate and periodic arrival. For a video with a frame rate of 60 frames per second (FPS), ideally, a picture frame arrives every 16.67 milliseconds (ms).

[0072] For XR and video transmission services, the generation and arrival of data packets are not continuous. On the UE side, the UE can listen to the downlink control signaling (downlink control information, DCI) of the network device in each time slot, so as to receive uplink authorization or downlink data according to the DCI, but the UE listens to the DCI in each time slot, which increases the power consumption of the UE. In order to reduce the power consumption of the UE, the UE can reduce the power consumption by stopping receiving the physical downlink control channel (physical downlink control channel, PDCCH) (PDCCH blind detection will be stopped at this time) when there is no downlink data transmission. Therefore, the 5G new radio (NR) introduces a discontinuous reception (DRX) mechanism for power saving. The DRX mechanism configures the DRX cycle for the UE. Figure 2 (a) is a schematic diagram of a DRX cycle. Figure 2As shown in (a), in each DRX cycle, an awake (on duration) period is configured. In the OnDuration period, the On Duration Timer starts, and the UE monitors and receives the PDCCH; in other periods, the UE has the opportunity to enter the sleep state and does not receive the PDCCH to reduce power consumption.

[0073] It should be noted that a UE in a dormant state can receive data from other physical channels, such as a physical downlink shared channel (PDSCH), an acknowledgement signal (ACK), etc. For example, in semi-persistent scheduling (SPS), a UE in a dormant state can receive a PDSCH sent on a periodically configured downlink subframe.

[0074] The determination of the DRX cycle needs to consider the balance between battery saving and data transmission delay. On the one hand, a longer DRX cycle is beneficial to reduce UE power consumption and extend UE battery life. On the other hand, a shorter DRX cycle can reduce data transmission delay. In order to balance the above two requirements, such as Figure 2 As shown in (b), two types of DRX cycles can be configured for the UE: a short DRX cycle (shortDRX-Cycle) and a long DRX cycle (longDRX-Cycle). At any time, the UE can use one of the configurations.

[0075] If the UE uses a short DRX cycle, the time domain start position of the DRX cycle can be determined according to the following formula:

[0076] [(SFN×10)+subframe number]modulo(drx-ShortCycle)=(drx-StartOffset)modulo(drx-ShortCycle).

[0077] If the UE uses a long DRX cycle, the time domain start position of the DRX cycle can be determined according to the following formula:

[0078] [(SFN×10)+subframe number]modulo(drx-LongCycle)=drx-StartOffset.

[0079] Among them, SFN represents the system frame number (system frame number) of the frame where the time domain starting position of the DRX cycle is located; subframe number represents the number of subframes included in the frame; modulo represents the modulo operation; drx-ShortCycle represents the cycle length of the configured short DRX cycle, drx-LongCycle represents the cycle length of the configured long DRX cycle, and the unit is milliseconds; drx-StartOffset represents the time domain starting position of the DRX cycle.

[0080] The network device can configure the relevant parameters of the DRX cycle through the DRX-Config configuration, as shown below:

[0081]

[0082]

[0083] Among them, drx-LongCycleStartOffset contains two parameters drx-StartOffset and drx-LongCycle. drx-StartOffset indicates the starting subframe of the DRX cycle, and drx-LongCycle indicates the cycle length of the long DRX cycle, or the number of consecutive subframes occupied by the long DRX cycle. drx-ShortCycle indicates the cycle length of the short DRX cycle, and drx-ShortCycleTimer is used to configure the number of short DRX cycles. drx-onDurationTimer is used to configure the length of the OnDuration period, and drx-SlotOffset is used to configure the delay in starting drx-onDurationTimer, that is, within the DRC cycle, drx-onDurationTimer starts at drx-SlotOffset after the start of the On Duration subframe. drx-SlotOffset is an offset within a subframe, which is less than 1ms.

[0084] In addition, the UE may also report the expected DRX cycle related parameters to the network device to provide a reference for the network device. Exemplarily, the DRX cycle related parameters may be reported in the form of auxiliary information through UE assistance information (UEAssistanceInformation).

[0085] For different multimedia services, the arrival period of their data may be different (for example, the frame rate of a video service may be 60 FPS, that is, the arrival period of a video frame is 16.67 ms, while the arrival period of audio data of an audio service may be 10 ms). Therefore, how to configure the DRX period for data of different services to save signaling overhead is an issue that needs to be considered.

[0086] In view of this, the embodiments of the present application provide a communication method and a communication device, which are beneficial to improving and solving the above-mentioned problems.

[0087] The specific implementation methods of this application are described by taking the terminal device and the network device as the execution subjects as examples. It is understandable that in each process, the function of the terminal device can be implemented by the terminal device, or by a module (such as a chip or circuit, etc.) in the terminal device, or by a logical node, logical module or software that can fully or partially implement the function of the terminal device. The function of the network device can be implemented by the network device, or by a module (such as a chip or circuit, etc.) in the network device, or by a logical node, logical module or software that can fully or partially implement the function of the network device.

[0088] Figure 3 This is a schematic flow chart of a communication method provided in an embodiment of the present application. The method may include at least the following steps.

[0089] S310, the network device determines first configuration information.

[0090] The first configuration information may be used to configure at least two discontinuous reception (DRX), or in other words, the first configuration information is used to configure relevant parameters of at least two DRXs.

[0091] In this application, DRX may sometimes be referred to as a DRX cycle, and the two may be interchangeable unless otherwise specified. In addition, the DRX cycle may be a short DRX cycle or a long DRX cycle. The following descriptions of the same or similar situations are omitted.

[0092] Exemplarily, the at least two DRXs may include a first DRX and a second DRX, that is, the first configuration information may configure the time domain starting position and / or cycle length of the first DRX, and the first configuration information may configure the time domain starting position and / or cycle length of the second DRX. The first configuration information configuring the time domain starting position and / or cycle length of the DRX (e.g., the first DRX and / or the second DRX) may be understood as the first configuration information including the time domain starting position and / or cycle length of the DRX.

[0093] The following takes the time domain starting position and / or cycle length of the first DRX configured by the first configuration information as an example to introduce the specific configuration method of configuring the at least two DRXs by the first configuration information.

[0094] In the case where the first configuration information configures the time domain starting position or cycle length of the first DRX, the first configuration information may specifically configure the first DRX by configuring the time domain starting position of the first DRX; or, the first configuration information configures the first DRX by configuring the time domain starting position offset of the first DRX; or, the first configuration information configures the first DRX by configuring the cycle length of the first DRX; or, the first configuration information configures the first DRX by configuring the cycle length offset of the first DRX.

[0095] In other words, the first configuration information can directly configure the time domain starting position or cycle length of the first DRX; the first configuration information can also configure the time domain starting position of the first DRX by configuring the time domain position offset of the first DRX, or configure the cycle length of the first DRX by configuring the cycle length offset of the first DRX.

[0096] Specifically, the network device may configure the first DRX according to the time domain starting position and the agreed value of the cycle length of the first DRX. That is, the first configuration information configures the first DRX by configuring the time domain starting position of the first DRX, and the cycle length of the first DRX is an agreed value, which may be agreed upon by a protocol, that is, the agreed value does not need to be configured separately.

[0097] Alternatively, the network device configures the first DRX according to the cycle length of the first DRX and the agreed value of the time domain starting position. That is, the first configuration information configures the first DRX by configuring the cycle length of the first DRX, and the time domain starting position of the first DRX is an agreed value, which can be agreed upon by the protocol, that is, the agreed value does not need to be configured separately.

[0098] Alternatively, the network device configures the first DRX according to the time domain starting position reference value, the time domain starting position offset of the first DRX and the agreed value of the cycle length. That is, the first configuration information can configure the time domain starting position of the first DRX by configuring the time domain starting position offset of the first DRX, and the time domain starting position of the first DRX can be determined by the time domain starting position reference value and the time domain starting position offset of the first DRX. Among them, the time domain starting position reference value can be an agreed value or configured by the first configuration information or other configuration information. The cycle length of the first DRX is an agreed value, for example, agreed by a protocol, and the agreed value does not need to be configured separately.

[0099] Alternatively, the network device configures the first DRX according to the cycle length reference value, the cycle length offset of the first DRX and the agreed value of the time domain starting position. That is, the first configuration information can configure the cycle length of the first DRX by configuring the cycle length offset of the first DRX, and the cycle length of the first DRX can be determined by the cycle length reference value and the cycle length offset of the first DRX. Among them, the cycle length reference value can be an agreed value or configured by the first configuration information or other configuration information. The time domain starting position of the first DRX is an agreed value, for example, agreed by a protocol, that is, the agreed value does not need to be configured separately.

[0100] In the case where the first configuration information configures the time domain starting position and the cycle length of the first DRX, the first configuration information may configure the first DRX by configuring the time domain starting position of the first DRX and the cycle length of the first DRX; or, the first configuration information may configure the first DRX by configuring the time domain starting position of the first DRX and the cycle length offset of the first DRX; or, the first configuration information may configure the first DRX by configuring the time domain starting position offset of the first DRX and the cycle length of the first DRX; or, the first configuration information may configure the first DRX by configuring the time domain starting position offset of the first DRX and the cycle length offset of the first DRX.

[0101] In other words, the first configuration information can directly configure the time domain starting position and cycle length of the first DRX; the first configuration information can also configure the time domain starting position of the first DRX by configuring the time domain position offset of the first DRX, and configure the cycle length of the first DRX by configuring the cycle length offset of the first DRX.

[0102] Specifically, the network device may configure the first DRX according to the time domain starting position of the first DRX and the cycle length of the first DRX, that is, the first configuration information configures the time domain starting position and cycle length of the first DRX.

[0103] Alternatively, the network device configures the first DRX according to the time domain starting position of the first DRX, the cycle length offset of the first DRX and the cycle length reference value. That is, the first configuration information configures the cycle length of the first DRX by configuring the cycle length offset of the first DRX. Specifically, the cycle length of the first DRX can be determined by the cycle length reference value and the cycle length offset of the first DRX. And, the first configuration information configures the time domain starting position of the first DRX. The cycle length reference value refers to the description above.

[0104] Alternatively, the network device configures the first DRX according to the time domain starting position offset of the first DRX, the time domain starting position reference value and the cycle length of the first DRX. That is, the first configuration information configures the time domain starting position of the first DRX by configuring the time domain starting position offset of the first DRX. Specifically, the time domain starting position of the first DRX can be determined by the time domain starting position reference value and the time domain starting position offset of the first DRX. And, the first configuration information configures the cycle length of the first DRX. The time domain starting position reference value refers to the description above.

[0105] Alternatively, the network device configures the first DRX according to the time domain starting position offset, the time domain starting position reference value, the cycle length offset and the cycle length reference value of the first DRX. That is, the first configuration information configures the cycle length of the first DRX by configuring the cycle length offset of the first DRX, and configures the time domain starting position of the defined DRX by configuring the time domain starting position offset of the defined DRX. Specifically, the cycle length of the first DRX can be determined by the cycle length reference value and the cycle length offset of the first DRX; the time domain starting position of the first DRX can be determined by the time domain starting position reference value and the time domain starting position offset of the first DRX. Among them, the cycle length reference value and the time domain starting position reference value can refer to the description above.

[0106] Similarly, the first configuration information also configures the time domain starting position and / or cycle length of the second DRX. The specific implementation of the first configuration information configuring the second DRX is similar to the first configuration information configuring the first DRX, which will not be repeated.

[0107] Optionally, the first configuration information may also configure at least one third DRX, or in other words, the at least two DRXs also include the at least one third DRX. Specifically, the first configuration information may configure the time domain starting position and / or cycle length of the at least one third DRX. The specific implementation of configuring each third DRX in the at least one third DRX by the first configuration information is similar to the configuration of the first DRX by the first configuration information, and will not be repeated here.

[0108] It should be understood that when the cycle length of each DRX in the at least two DRXs is determined by a cycle length agreed value and / or a cycle length reference value, and the time domain starting position of each DRX is determined by a time domain starting position agreed value and / or a time domain starting position reference value, the cycle length agreed value and / or cycle length reference value corresponding to the at least two DRXs may be the same or different. For example, all DRXs may share a cycle length agreed value and / or a cycle length reference value, or some DRXs may share a cycle length agreed value and / or a cycle length reference value, or each DRX corresponds to a different cycle length agreed value and / or cycle length reference value. Similarly, the time domain starting position agreed values ​​corresponding to the at least two DRXs may be the same or different.

[0109] Taking the first configuration information configuring the cycle length and the time domain starting position of the first DRX, and the first configuration information configuring the cycle length and the time domain starting position of the second DRX as an example, the first configuration information may be a DRX configuration (DRX-Config), and the first configuration information is as follows:

[0110]

[0111] Among them, when the first DRX and the second DRX are long DRX cycles, the drx-LongCycleStartOffset[1] and drx-LongCycleStartOffset[2] fields are used to configure the cycle length and time domain starting position of the first DRX, and the cycle length and time domain starting position of the second DRX, respectively; when the first DRX and the second DRX are short DRX cycles, the drx-ShortCycle[1] and drx-ShortCycle[2] fields are used to configure the cycle lengths of the first DRX and the second DRX, respectively, and the drx-SlotOffset field configures the time domain starting position of the first DRX and the second DRX. ENUMERATED indicates an enumerated type parameter. For example, drx-ShortCycle[1]ENUMERATED{ms2,ms3,ms4,ms5,ms6,ms7,ms8,ms10,ms14,ms16,ms20,ms30,ms32,ms35,ms40,ms64,ms80,ms128,ms160,ms256,ms320,ms512,ms640,spare9,spare8,spare7,spare6,spare5,spare4,spare3,spare2,spare1} means that drx-ShortCycle[1] can be set to one of the above values, spare refers to an alternative; INTEGER(1..31) means that drx-SlotOffset can be set to an integer between 1 and 31.

[0112] like Figure 4 As shown in (a), assuming that there are data streams of two services at this time, for example, the two services are video service and audio service, the network device can configure the DRX cycle length and time domain starting position corresponding to the video service through DRX-Config, such as drx-ShortCycle[1] and drx-StartOffset[1] respectively, and DRX-Config also configures the DRX cycle length and time domain starting position corresponding to the audio service, such as drx-ShortCycle[2] and drx-StartOffset[2] respectively.

[0113] Taking the first configuration information configuring the cycle length and time domain starting position of the first DRX, and the first configuration information configuring the cycle length offset and time domain starting position offset of the second DRX as an example, the first configuration information may be a DRX configuration (DRX-Config), and the first configuration information is as follows:

[0114]

[0115] Among them, when the first DRX and the second DRX are long DRX cycles, the drx-LongCycleStartOffset field is used to configure the cycle length and time domain starting position of the first DRX, and configure the cycle length of the second DRX; the drx-StartOffset-offset[1] field is used to configure the time domain starting position offset of the second DRX; when the first DRX and the second DRX are short DRX cycles, the drx-ShortCycle field is used to configure the cycle length of the first DRX, the drx-ShortCycle-offset[1] field is used to configure the cycle length offset of the second DRX, and the drx-SlotOffset field configures the time domain starting position of the first DRX and the second DRX.

[0116] like Figure 4 As shown in (b), assuming that there are data streams of two services at this time, for example, the two services are video service and audio service, the network device can configure the DRX cycle length and starting position corresponding to the video service through DRX-Config, such as drx-ShortCycle and drx-StartOffset, respectively, and DRX-Config also configures the DRX cycle length offset and time domain starting position corresponding to the audio service, such as drx-ShortCycle+drx-ShortCycle-offset[1] and drx-StartOffset, respectively.

[0117] Optionally, before the network device determines the first configuration information, the network device may determine the cycle length of each DRX of the at least two DRXs based on the cycle information of the arrival of the service data; further, the network device determines the time domain starting position of the DRX based on the cycle length of each DRX.

[0118] Exemplarily, the network device obtains periodic information of data arrival of at least two services, and the at least two services may correspond one-to-one to the at least two DRXs.

[0119] For example, the network device obtains the DRX cycle length corresponding to the service by obtaining the configuration information of the service quality (QoS) flow. For example, the configuration information of the QoS flow may include a QoS template (QoS profile), and the QoS profile includes the arrival cycle of the service data.

[0120] For another example, the network device may estimate the arrival period of the service data by detecting the arrival time interval of the data packets in the QoS flow.

[0121] In addition, for uplink transmission, the terminal device knows the arrival period of the service data. The terminal device can report the arrival period of the service data to the network device in the form of auxiliary information or the like.

[0122] Exemplarily, data of a video service is transmitted between the network device and the terminal device, and the frame rate (frame per second, FPS) of the video service is 60 frames per second. Ideally, a picture frame arrives every 50 / 3 milliseconds, and the configured DRX cycle length can be equal to 50 / 3 milliseconds.

[0123] The service corresponding to DRX mentioned above can be understood as receiving data of the service during the wake-up period corresponding to the DRX cycle.

[0124] Exemplarily, the network device determines the time domain starting position of each DRX by the following formula, where formula (1) and formula (2) correspond to the case where the DRX is a short DRX cycle and a long DRX cycle respectively:

[0125] [(SFN×10)+subframe number]modulo(drx-ShortCycle[i])=(drx-StartOffset[i])modulo(drx-ShortCycle[i])(1)

[0126] [(SFN×10)+subframe number] modulo (drx-LongCycle[i]) = drx-StartOffset[i] (2)

[0127] Among them, SFN represents the system frame number of the frame where the time domain starting position of DRX is located; subframe number represents the number of subframes included in the frame; modulo represents the modulo operation; drx-ShortCycle[i] or drx-LongCycle[i] represents the cycle length of the i-th DRX in at least two DRXs, drx-ShortCycle[i] represents the cycle length of the short DRX cycle, drx-LongCycle[i] represents the cycle length of the long DRX cycle, and drx-StartOffset[i] represents the time domain starting position of the i-th DRX.

[0128] Optionally, the network device determines the time domain starting position of each DRX by using formula (3) to formula (5), and the DRX is a short DRX cycle:

[0129] [(SFN×10)+subframe number]modulo(drx-ShortCycle+drx-ShortCycle-offset[i])=(drx-StartOffset[i])

[0130] modulo(drx-ShortCycle[i])(3)

[0131] [(SFN×10)+subframe number]modulo(drx-ShortCycle[i])=(drx-StartOffset+drx-StartOffset-offset[i])

[0132] modulo(drx-ShortCycle[i])(4)

[0133] [(SFN×10)+subframe number]modulo(drx-ShortCycle+drx-ShortCycle-offset[i])=(drx-StartOffset+drx-

[0134] StartOffset-offset[i])modulo(drx-ShortCycle+drx-ShortCycle-offset[i])(5)

[0135] Wherein, SFN, subframe number, drx-ShortCycle[i] and drx-StartOffset[i] refer to the description in formula (1); modulo represents modulo operation; drx-ShortCycle represents a cycle length reference value, drx-ShortCycle-offset[i] represents a cycle length offset of the i-th DRX among at least two DRXs, drx-StartOffset represents a time domain starting position reference value, and drx-StartOffset-offset[i] represents a time domain starting position offset of the i-th DRX among at least two DRXs.

[0136] Optionally, the network device determines the time domain starting position of each DRX by using formula (6) to formula (8), and the DRX is a long DRX cycle:

[0137] [(SFN × 10) + subframe number] modulo (drx-LongCycle + drx-LongCycle-offset[i]) = drx-StartOffset[i]) (6)

[0138] [(SFN × 10) + subframe number] modulo (drx-LongCycle [i]) = drx-StartOffset+drx-StartOffset-offset[i] (7)

[0139] [(SFN×10)+subframe number]modulo(drx-LongCycle+drx-LongCycle-offset[i])=drx-StartOffset+drx-

[0140] StartOffset-offset[i](8)

[0141] Wherein, SFN, subframe number, drx-ShortCycle[i] and drx-StartOffset[i] refer to the description in formula (2); modulo represents modulo operation; drx-LongCycle represents a cycle length reference value, drx-LongCycle-offset[i] represents a cycle length offset of the i-th DRX among at least two DRXs, drx-StartOffset represents a time domain starting position reference value, and drx-StartOffset-offset[i] represents a time domain starting position offset of the i-th DRX among at least two DRXs.

[0142] Optionally, the first configuration information can also configure the duration of the wake-up period of each of the at least two DRXs. The duration of the wake-up period of the at least two DRXs can be the same or different, and the present application does not limit this. Taking the first configuration information as DRX-Config as an example, the duration of the wake-up period can be configured through the drx-onDurationTimer field. Optionally, when the duration of the wake-up period of at least two DRXs is different, the duration of the wake-up period of the i-th DRX in the at least two DRXs can be configured by adding the drx-onDurationTimer[i] field; Optionally, the duration of the wake-up period of the at least two DRXs can also be configured by configuring a wake-up period reference value, and the offset value of the duration of the wake-up period of each DRX in the at least two DRXs relative to the wake-up period reference value.

[0143] S320: The network device sends the first configuration information to the terminal device.

[0144] Correspondingly, the terminal device receives the first configuration information from the network device.

[0145] Exemplarily, the first configuration information is carried in radio resource control (RRC) signaling, a medium access control (MAC) control element (CE), or other downlink signaling.

[0146] S330, the network device sends service data to the terminal device.

[0147] Accordingly, the terminal device receives data of the service from the network device.

[0148] Specifically, the network device may send data of at least two services to the terminal device, and the data of the at least two services may correspond to the at least two DRXs respectively.

[0149] Exemplarily, when a data packet of a service arrives at a network device, the network device sends a PDCCH to a terminal device, and the PDCCH includes downlink control information (DCI), and the DCI is used to schedule the terminal device to receive downlink data on a corresponding downlink resource, i.e., a physical downlink shared channel (PDSCH). Accordingly, the terminal device monitors the PDCCH during the wake-up period (On Duration) of the DRX cycle and receives the downlink data.
