Description

Communication method, communication device and storage medium

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on March 18, 2024, with application number 202410310561.5 and invention name “A communication method, communication device and storage medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method, a communication device, and a storage medium. Background Art

[0003] A multimodal extended reality device refers to a device that performs multimodal services. A multimodal service may include data of multiple service types, and this data can come from a terminal device, a terminal device connected to one or more devices, or multiple terminal devices.

[0004] When transmitting data, a terminal device typically uses discontinuous reception (DRX) to save power. Different types of services typically require different DRX settings. Therefore, when transmitting multimodal services, a terminal device typically needs to configure multiple sets of DRX parameters.

[0005] However, once multiple sets of DRX configuration parameters are configured for a terminal device, the terminal device will experience intensive monitoring in the time domain. Moreover, if data retransmission is allowed at each monitoring opportunity, the monitoring time of the terminal device may be too long, failing to achieve the goal of saving power. Summary of the Invention

[0006] The present application provides a communication method, a communication device, and a storage medium, the purpose of which is to reduce the power consumption of a terminal device.

[0007] In order to achieve the above objectives, this application provides the following technical solutions:

[0008] A first aspect of the present application provides a communication method, applied to a network device, the method comprising:

[0011] In a possible implementation of the first aspect of the present application, the sending of DRX indication information of discontinuous reception (DRX) to the terminal device includes: sending DRX to the terminal device, wherein the DRX includes the DRX indication information. In the above implementation, the network device can directly add DRX indication information in the DRX for indicating that the DRX enables retransmission or for indicating that the DRX disables retransmission, so that when the terminal device receives the DRX, it can directly disable retransmission according to the DRX indication information in the DRX, thereby reducing the monitoring time of the terminal device and reducing the power consumption of the terminal device.

[0012] In a possible implementation of the first aspect of the present application, the DRX indication information is used to indicate that at least one set of DRX configuration parameters in the DRX is to be disabled for retransmission.

[0064] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be limiting of the present application. As used in the specification and appended claims of the present application, the singular expressions "one", "a kind of", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context. It should also be understood that in the embodiments of the present application, "one or more" refers to one, two or more; "and / or" describes the association relationship of associated objects, indicating that three relationships may exist; for example, A and / or B can represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship.

[0065] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0066] The "multiple" involved in the embodiments of the present application means greater than or equal to two. It should be noted that in the description of the embodiments of the present application, the words "first" and "second" are only used for the purpose of distinguishing the description and cannot be understood as indicating or implying relative importance or order.

[0067] The embodiments of the present application are applied to communication systems, which may be second-generation (2G) communication systems, third-generation (3G) communication systems, LTE systems, fifth-generation (5G) communication systems, LTE and 5G hybrid architectures, 5G New Radio (5G NR) systems, and new communication systems that may emerge in future communication developments.

[0068] The communication system includes a first device and a second device. The first device can be a device on the network side for providing network communication functions, which is sometimes also called a network device or a network element. The network device can generally be a base station (including a functional unit of a base station, or a combination of functional units of a base station) or a core network unit, wherein the core network unit can be a functional unit in the core network, including but not limited to an Access and Mobility Management Function (AMF) unit or a Session Management Function (SMF) unit. The second device can be a device for accessing the network, which can generally be a terminal device. An example of a communication system is shown in Figure 1, which includes a base station 11 and a terminal 12.

[0069] In the embodiments provided in the present application, the base station can be any device with wireless transceiver functions, including but not limited to: an evolved base station (NodeB or eNB or e-NodeB, evolutionary Node B) in long term evolution (LTE), a base station (gNodeB or gNB) or a transmission receiving point (TRP) in new radio (NR), a base station of subsequent evolution of 3GPP, an access node in a Wi-Fi system, a wireless relay node, a wireless backhaul node, etc. The base station can be: a macro base station, a micro base station, a pico base station, a small station, a relay station, or a balloon station, etc. The base station can include one or more co-site or non-co-site transmission points (Transmission Reception Point, TRP). The base station can also be a wireless controller, a centralized unit (CU), and / or a distributed unit (DU) in a cloud radio access network (CRAN) scenario. The base station can communicate with a terminal device, or communicate with the terminal device through a relay station. The terminal device can communicate with multiple base stations of different technologies. For example, the terminal device can communicate with a base station that supports the LTE network, and can also communicate with a base station that supports the 5G network. It can also establish dual connections with a base station that supports the LTE network and a base station that supports the 5G network.

[0070] In the embodiments provided herein, the terminal device may be in various forms, such as a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a vehicle-mounted terminal device, a wireless terminal device in self-driving, a wireless terminal device in remote medical, a wireless terminal device in smart grid, a wireless terminal device in transportation safety, a wireless terminal device in smart city, a wireless terminal device in smart home, a wearable terminal device, etc. The terminal device may also be sometimes referred to as a terminal device, user equipment (UE), an access terminal device, a vehicle-mounted terminal device, an industrial control terminal device, a UE unit, a UE station, a mobile station, a mobile station, a remote station, a remote terminal device, a mobile device, a UE terminal device, a terminal device, a wireless communication device, a UE agent, or a UE device, etc. The terminal device may also be a fixed terminal device or a mobile terminal device.

[0071] In a communication system, multimodal extended reality (XR) devices may include the following two situations: one situation is that the multimodal XR device may be a single terminal, and one terminal generates a multimodal service (a multi-modal service), and the multimodal service includes multiple data streams; the other situation is that the multimodal XR device may be multiple terminals, each terminal generates several data streams, and a multimodal service consists of multiple data streams generated by multiple terminals.

[0072] The multimodal service in the embodiment of the present application is composed of several interrelated data streams, which can also be called multimodal streams. These data streams may come from different sources. A data stream can be called unimodal data, and a data stream can be regarded as a type of data associated with the same communication service. For example, the data stream in the embodiment of the present application can be audio data, video data, positioning data, and tactile data. The data stream of the multimodal service can come from a single UE, or via a single device, or via multiple devices connected to a single UE that can access the communication system, or from multiple UEs.

[0073] In the embodiments of the present application, the requirements of the multimodal service refer to the service requirements of the multimodal service, for example, the quality of service (QoS) monitoring requirements of multiple Internet Protocol (IP) data flows related to the multimodal service.

[0074] Discontinuous Reception (DRX) in the embodiment of the present application is a method for optimizing energy efficiency from the link layer of a wireless communication system. It allows the terminal device to turn off the wireless transceiver unit when no data transmission is performed, thereby entering a low-power state. This mechanism is crucial to improving the energy efficiency and service quality of mobile communication systems because it can maximize the battery life of user terminals without affecting the user experience. In mobile communication systems, DRX is not limited to the idle state, but also applies to the connected state. As shown in Figure 2, DRX involves multiple timers and related operations, such as:

[0075] On Duration Timer: refers to the duration of monitoring required at the beginning of the DRX cycle.

[0076] Inactive Timer: refers to the duration of monitoring after the Physical Downlink Control Channel (PDCCH) indicates that new data needs to be transmitted.

[0077] Round Trip Time (RTT) Timer: This is divided into the Uplink Round Trip Time (HARQ RTT Timer UL) and the Downlink Round Trip Time (HARQ RTT Timer DL). The Uplink Round Trip Timer is the minimum time required to receive an uplink Hybrid Automatic Repeat Request (HARQ) retransmission. The Downlink Round Trip Timer is the minimum time required to receive a downlink HARQ retransmission allocation.

[0078] Retransmission timer (ReTx timer): It can be divided into uplink retransmission timer (Retransmission Timer UL) and downlink retransmission timer (Retransmission Timer DL). The uplink retransmission timer is the maximum time interval until an uplink data retransmission grant is received. The downlink retransmission timer is the maximum time interval until a downlink data retransmission is received.

[0079] In order to make the technical solution of this application clearer, the DRX configuration parameters are specifically introduced below:

[0080] Drx-on Duration Timer: duration at the start of the drx cycle;

[0081] Drx-Slot Offset: The delay before starting the drx-on Duration Timer;

[0082] Drx-Inactivity Timer: The duration after the PDCCH opportunity when the PDCCH indicates a new uplink (UL), downlink (DL) or signaling link (SL) transmission of the Medium Access Control (MAC) entity;

[0083] Drx-Retransmission Timer DL: (for each DL HARQ process except the broadcast process): Maximum duration before a DL retransmission is received;

[0084] Drx-Retransmission Timer UL (per UL HARQ process): maximum duration before receiving an UL retransmission grant;

[0085] Drx-Long Cycle Start Offset: drx-Start Offset of the long DRX cycle and the cycle start subframe that defines the long and short DRX cycles;

[0086] Drx-Non Integer Long Cycle Start Offset (optional): When the length of the long DRX cycle and / or the short DRX cycle is not an integer, the long DRX cycle and drx-StartOffset define the subframes where the long and short DRX cycles start;

[0087] Drx-Short Cycle (optional): short DRX cycle;

[0088] Drx-Non Integer Short Cycle (optional): a short DRX cycle whose length is not an integer;

[0089] Drx-Short Cycle Timer (optional): duration of the short DRX cycle that the UE should follow;

[0090] Drx-HARQ RTT Timer DL (for each DL HARQ process except the broadcast process): the minimum duration before a DL allocation that the MAC entity expects to be used for HARQ retransmissions;

[0091] Drx-HARQ RTT Timer UL (per UL HARQ process): minimum duration before UL HARQ retransmission is granted expected by the MAC entity;

[0092] Drx-Last Transmission UL (optional): Configuration of starting the Drx-HARQ RTT Timer UL after the last transmission within the bundle;

[0093] ps wakeup (optional): starts the configuration of the related Drx-on Duration Timer when the Digital Communication Protocol (DCP) is monitored but not detected;

[0094] Download HARQ Feedback Disabled (optional): Disables the HARQ feedback configuration for each DL HARQ process;

[0095] Uplink HARQ mode (optional): Set HARQmodeA or HARQmodeB for each UL HARQ process;

[0096] Disable CG Retransmission Monitoring (optional): disables the configuration of starting Drx-HARQ RTT Timer UL for UL transmission on the configured uplink grant;

[0097] Drx-Time Reference SFN (optional): When the short and / or long DRX cycles are not integers, the reference system frame number (SFN) used to determine the DRX start time over the duration.

[0098] When a terminal device is transmitting data, it is usually necessary to use DRX to achieve power saving, and different types of service data usually require different DRX. Therefore, when a terminal device is transmitting multimodal service data, since multimodal service data usually includes data of multiple service types, the network device needs to configure multiple sets of DRX configuration parameters for the terminal device. However, once multiple sets of DRX configuration parameters are configured for a terminal device, since the monitoring time of each set of DRX configuration parameters may be different, the terminal may experience intensive monitoring time in the time domain.

[0099] The specific process of data retransmission by a terminal device during data transmission is typically to activate a round-trip timer when data is detected during the inactivity timer's listening time, activate a retransmission timer after the round-trip timer's listening time expires, and finally complete data retransmission scheduling within the retransmission timer's listening time. Therefore, if data retransmission is allowed during each listening time, the terminal device will require more listening time to transmit or receive data, which may result in the terminal device listening for an excessively long time, ultimately preventing the terminal device from achieving the goal of saving power. The present application provides a communication method that can reduce the listening time of a terminal device, thereby reducing the power consumption of the terminal device.

[0100] In order to make the technical solution of the present application clearer and easier to understand, the communication method of the multimodal service of the embodiment of the present application is introduced below in conjunction with the accompanying drawings. The embodiment of the present application is applicable to the data transmission process in the wireless communication scenario. In the embodiment of the present application, the multimodal service transmission between the terminal device and the network device is taken as an example, such as the multimodal service transmission between a single terminal device and the network device. The above-mentioned multimodal service between the terminal device and the network device is only a feasible example. The embodiment of the present application can be applied to the data transmission between the terminal device and the terminal device, or the data transmission between the network device and the network device, or the data transmission between two network elements in the wireless communication network.

[0101] Please refer to FIG3 , which is a schematic diagram of an interaction process between a network device and a terminal device provided in an embodiment of the present application. The communication method provided in an embodiment of the present application mainly includes the following steps:

[0102] 301. The network device sends DRX indication information of discontinuous reception (DRX) to the terminal device.

[0103] The DRX indication information is used to instruct DRX to enable retransmission or to instruct DRX to disable retransmission.

[0104] In an embodiment of the present application, in order to reduce the listening time of a terminal device and reduce the power consumption of the terminal device, the network device may send DRX indication information for indicating that DRX enables retransmission or for indicating that DRX disables retransmission to the terminal device, so that the terminal device can disable retransmission according to the DRX indication information sent by the network device, thereby reducing the listening time and thus reducing the power consumption of the terminal device. Enabling retransmission can be understood as the terminal device being able to retransmit in the current DRX cycle; disabling retransmission can be understood as the terminal device not being able to retransmit in the current DRX cycle. Retransmission means that the terminal device receives or transmits retransmission information according to the retransmission timer and the round-trip timer. Even if there is no retransmission scheduling, the terminal device will receive retransmission information according to the retransmission timer and the round-trip timer. When retransmission is disabled, the terminal device does not receive retransmission information according to the retransmission timer and the round-trip timer, or the terminal device does not start the retransmission timer and the round-trip timer. In this case, the terminal device will not receive retransmission or transmit retransmission.

[0105] Specifically, the network device and the terminal device can communicate with each other. After sending the configured DRX to the terminal device, the network device can send DRX indication information to the terminal device, so that the terminal device can receive the DRX indication information and enable retransmission or disable retransmission of DRX according to the DRX indication information, so that the terminal device can reduce the listening time by disabling retransmission when monitoring according to the DRX indication information and DRX, thereby reducing the power consumption of the terminal device.

[0106] In a possible implementation of the embodiment of the present application, step 301 in which the network device sends DRX indication information of discontinuous reception (DRX) to the terminal device includes:

[0107] A1. Send DRX to the terminal device.

[0108] The DRX includes the DRX indication information.

[0109] In an embodiment of the present application, the network device and the terminal device can communicate with each other, and the network device can include DRX indication information in the DRX configuration information, that is, the DRX configuration information can be composed of DRX configuration parameters and DRX indication information, and the DRX configuration information can also be referred to as DRX, and the DRX is sent to the terminal device, so that the terminal device can extract the DRX indication information from the DRX when receiving the DRX, so that the terminal device can reduce the listening time by disabling retransmission when monitoring according to the DRX indication information and the DRX configuration parameters, thereby reducing the power consumption of the terminal device.

[0110] In an embodiment of the present application, the DRX configured by the network device may include a DRX configuration parameter for disabling retransmission. The DRX configuration parameter for disabling retransmission may be a DRX configuration parameter pre-configured by the network device. For the DRX configuration parameter or DRX cycle for which retransmission needs to be disabled, the network device may not configure the corresponding round-trip time timer and retransmission timer, so that after the network device sends the DRX to the terminal device, the terminal device does not monitor for retransmission, thereby reducing the monitoring time of the terminal device and reducing the transmission power consumption of the terminal device.

[0111] In an embodiment of the present application, before a network device sends DRX indication information, the network device may configure DRX and DRX indication information based on the service type of the terminal device, where the service type may include multimodal services. Since the terminal device generally needs to use DRX to save power during data transmission, and different types of service data generally require different DRXs, and multimodal service data may include data of multiple different service types, the DRX configured by the network device may include one set of DRX configuration parameters or multiple sets of DRX configuration parameters, wherein each set of DRX configuration parameters corresponds to a type of service data or service cycle, and the cycles of each set of DRX configuration parameters may be different, that is, there may be multiple cycles in the multiple sets of DRX configuration parameters, or each set of DRX configuration parameters includes multiple cycles, or there may be multiple monitoring opportunities within the cycle of each set of DRX configuration parameters, that is, the DRX configured by the network device may include multiple sets of DRX configuration parameters, or include multiple DRX cycles, or there may be one or more monitoring opportunities within the included DRX cycles. Multiple sets of DRX configurations mean that each set of DRX configurations includes one or more DRX configuration parameters. Therefore, after configuring DRX, the network device can first determine the DRX configuration parameters that can enable retransmission, or determine the DRX cycle that can enable retransmission, or determine the monitoring time that can enable retransmission, and then configure DRX indication information to indicate the DRX configuration parameters that can enable retransmission, or the DRX cycle that can enable retransmission, or the monitoring time that can enable retransmission to enable retransmission.

[0112] Specifically, when configuring the DRX indication information, the network device may determine the DRX configuration parameters capable of disabling retransmission according to the DRX cycle, or determine the DRX cycle capable of disabling retransmission, or determine the monitoring timing capable of disabling retransmission.

[0113] When the packet delay budget (PDB) for certain service types is long and the DRX cycle is short, it is not necessary to immediately transmit monitoring or transmission data within the DRX cycle. Instead, the data can be retransmitted during the monitoring period of the next DRX cycle. This means disabling the round-trip timer and retransmission timer in the DRX configuration parameters corresponding to this service type without affecting the content and quality of data transmission. Therefore, network devices can analyze the DRX configuration parameter cycle to determine whether the DRX configuration parameters can be disabled for retransmission without affecting the content and quality of data transmission.

[0114] Since the DRX cycle directly determines the time point for the next data retransmission, the smaller the DRX cycle, the more likely it is to meet the PDB requirements, that is, the more likely it is to disable the monitoring timer without affecting the data transmission content and quality. For example, the PDB of video service data can be between 10ms and 30ms, and each frame rate will have a corresponding delay requirement. For example, when fps=60, the corresponding PDBs include 10ms, 15ms and 30ms. In this case, the DRX cycle of the DRX configuration parameters corresponding to the video service data is 16.67ms. Then, the interval between the time point of data retransmission in the next cycle of the video service data and the time point of data monitoring in the current cycle will be greater than 30ms. That is, the DRX configuration parameters corresponding to the video service data do not recommend disabling the monitoring timer for retransmission under this delay requirement.

[0115] For example, when fps = 120, the DRX cycle of the DRX configuration parameters corresponding to the video service data is less than 10ms, and the PDB requirement is 30ms. At this time, the video service data can complete retransmission scheduling within the next cycle and meet the PDB requirement, that is, the DRX configuration parameters corresponding to the video service data can disable retransmission of the monitoring timer under the delay requirement.

[0116] For another example, the period of the DRX configuration parameters corresponding to the tactile service data is usually 2ms or 4ms, and the PDB requirement of the tactile service is 10ms. In this case, if the period of the DRX configuration parameters corresponding to the tactile service data is 2ms, then the tactile service data can complete the retransmission scheduling within the next period and meet the PDB requirements, that is, the DRX configuration parameters corresponding to the tactile service data can disable the retransmission of the monitoring timer under the delay requirement.

[0117] In a possible implementation of an embodiment of the present application, the DRX indication information is used to indicate at least one set of DRX configuration parameters in the DRX to disable retransmission. If the DRX includes one or more sets of DRX configuration parameters, the DRX indication information can be used to indicate one or more sets of DRX configuration parameters in the DRX to disable retransmission. For example, referring to Figure 4, if the DRX includes two sets of DRX configuration parameters, DRX1 and DRX2, and it is determined through analysis that DRX2 is a DRX configuration parameter that can disable retransmission, the DRX indication information sent by the network device to the terminal device can be used to indicate DRX2 to disable retransmission, so that the terminal device can reduce the listening time by disabling retransmission of DRX2 when monitoring, thereby reducing the power consumption of the terminal device.

[0118] In a possible implementation of an embodiment of the present application, the DRX indication information is used to indicate that at least one DRX cycle in the DRX is to be disabled for retransmission. If the DRX includes one or more DRX cycles, the DRX indication information can be used to indicate that one or more DRX cycles in the DRX are to be disabled for retransmission. For example, referring to FIG5 , if the DRX includes two DRX cycles, cycle 1 and cycle 2, and DRX2 is determined through analysis to be a DRX cycle in which retransmission can be disabled, the DRX indication information sent by the network device to the terminal device can be used to indicate that cycle 2 is to be disabled for retransmission, so that the terminal device can reduce the listening time by disabling the retransmission cycle 2 when monitoring, thereby reducing the power consumption of the terminal device.

[0119] In a possible implementation of an embodiment of the present application, the DRX indication information is used to indicate at least one listening opportunity in a DRX cycle in the DRX to enable retransmission. If a DRX cycle included in the DRX includes one or more listening opportunities, the DRX indication information can be used to indicate one or more listening opportunities in a DRX cycle in the DRX to enable retransmission. For example, referring to Figure 6, if the cycle 1 included in the DRX includes three listening opportunities, and it is determined through analysis that the second listening opportunity and the third listening opportunity in the cycle 1 are DRX cycles that can disable retransmission, the DRX indication information sent by the network device to the terminal device can be used to indicate the second listening opportunity and the third listening opportunity in the cycle 1 to disable retransmission, so that the terminal device can reduce the listening time by disabling the second listening opportunity and the third listening opportunity in the retransmission cycle 1 when monitoring, thereby reducing the power consumption of the terminal device.

[0120] In a possible implementation of an embodiment of the present application, when the DRX indication information is used to instruct DRX to disable retransmission, the DRX indication information includes at least one of a first indication, a second indication, a third indication, and a fourth indication; wherein the first indication is used to instruct to disable retransmission; the second indication is used to instruct to disable a round-trip timer; the third indication is used to instruct that a value of the round-trip timer is infinite; and the fourth indication is used to instruct that a value of the retransmission timer is zero. The DRX indication information sent by the network device to the terminal device may directly instruct to disable retransmission, so that the terminal device may directly disable the retransmission of the corresponding DRX configuration parameters, DRX cycle, or monitoring opportunities within the DRX cycle after receiving the DRX indication information. The DRX indication information sent by the network device to the terminal device may also instruct to disable the round-trip time timer, so that the terminal device may disable retransmission by disabling the round-trip time timer after receiving the DRX indication information. The DRX indication information sent by the network device to the terminal device may also instruct to set a value of the round-trip time timer to infinite, so that the terminal device may disable retransmission by setting a value of the round-trip time timer to infinite after receiving the DRX indication information. The DRX indication information sent by the network device to the terminal device may also indicate that the value of the retransmission timer is zero, so that the terminal device can disable retransmission by setting the value of the retransmission timer to zero after receiving the DRX indication information.

[0121] In a possible implementation of an embodiment of the present application, the round-trip time timer includes at least one of an uplink round-trip time timer and a downlink round-trip time timer; and the retransmission timer includes at least one of an uplink retransmission time timer and a downlink retransmission time timer. Since the terminal device can be divided into uplink data transmission and downlink data reception when transmitting multimodal service data, when the data transmitted by the terminal device is uplink data, the DRX indication information can indicate the disabling of retransmission by indicating that the uplink round-trip time timer is turned off, or by indicating that the value of the uplink round-trip time timer is infinite, or by indicating that the value of the uplink retransmission timer is zero, so that the terminal device can disable retransmission when transmitting uplink data, thereby reducing the listening time during uplink data transmission, thereby reducing the power consumption of the terminal device when transmitting multimodal service data. When the data received by the terminal device is downlink data, the DRX indication information can indicate that the downlink round-trip time timer is turned off, or by indicating that the value of the downlink round-trip time timer is infinite, or by indicating that the value of the downlink retransmission timer is zero, to indicate that retransmission is disabled when the terminal device receives downlink data, thereby reducing the listening time during downlink data transmission and thus reducing the power consumption of the terminal device.

[0122] In a possible implementation of an embodiment of the present application, the DRX indication information includes at least one disabling indicator, and the disabling indicator is used to indicate that the DRX configuration parameter corresponding to the position of the disabling indicator disables retransmission, and there is a corresponding relationship between the position of the disabling indicator and the configuration order of the DRX configuration parameters. The network device can design the DRX indication information based on the Medium Access Control Control Element (MAC CE). As shown in Figure 7, the indication information can be composed of a label identifier R and a disabling indicator A / D. Each disabling indicator A / D corresponds to a set of DRX configuration parameters, and each disabling indicator A / D is used to indicate whether the corresponding DRX configuration parameter disables retransmission or enables retransmission. The correspondence between the disabling indicator and the DRX configuration parameter can be determined according to the position of the disabling indicator and the configuration order of the DRX configuration parameters. Specifically, the first disabling indicator closest to the tag identifier R can be used to indicate that the first set of DRX configuration parameters is to be disabling retransmission, the second disabling indicator can be used to indicate that the second set of DRX configuration parameters is to be disabling retransmission, and so on, so that the DRX indication information can be used to disable retransmission of the corresponding DRX configuration parameters through the disabling indicator, so that the terminal device can reduce the listening time and reduce the power consumption of the terminal device.

[0123] In a possible implementation of an embodiment of the present application, the DRX indication information includes at least one disabling indicator, and the disabling indicator is used to indicate that the DRX cycle corresponding to the position of the disabling indicator disabling retransmission, and the position of the disabling indicator corresponds to the configuration order of the DRX cycle. As shown in Figure 7 above, each disabling indicator A / D corresponds to a DRX cycle, and each disabling indicator A / D is used to indicate that the corresponding DRX cycle disabling retransmission or enabling retransmission. The correspondence between the disabling indicator and the DRX cycle can be determined according to the position of the disabling indicator and the configuration order of the DRX cycle. Specifically, the first disabling indicator closest to the label identifier R can be used to indicate that the first DRX cycle disabling retransmission, the second disabling indicator can be used to indicate that the second DRX cycle disabling retransmission, and so on, so that the DRX indication information can realize the disabling retransmission of the corresponding DRX cycle through the disabling indicator, so that the terminal device can reduce the monitoring time and reduce the power consumption of the terminal device.

[0124] In a possible implementation of the first aspect of the present application, the DRX indication information includes at least one disabling indicator, the disabling indicator being used to indicate that the listening opportunity corresponding to the position of the disabling indicator is to disable retransmission, and the position of the disabling indicator corresponds to the configuration order of the listening opportunities. As shown in FIG7 above, each disabling indicator A / D corresponds to a listening opportunity in a DRX cycle, and each disabling indicator A / D is used to indicate whether the corresponding listening opportunity is to disable retransmission or enable retransmission. The correspondence between the disabling indicator and the listening opportunity can be determined based on the position of the disabling indicator and the configuration order of the DRX cycle. Specifically, the first disabling indicator closest to the tag identifier R can be used to indicate that the first listening opportunity in a DRX cycle is to disable retransmission, the second disabling indicator can be used to indicate that the second listening opportunity in a DRX cycle is to disable retransmission, and so on, so that the DRX indication information can achieve the disabling retransmission of the corresponding DRX cycle through the disabling indicator, so that the terminal device can reduce the listening time and reduce the power consumption of the terminal device.

[0125] In a possible implementation of the first aspect of the present application, the DRX indication information includes at least one disabling indicator and at least one DRX configuration parameter identifier, and the disabling indicator is used to indicate that the DRX configuration parameter corresponding to the corresponding DRX configuration parameter identifier is disabling retransmission. As shown in Figure 8, the indication information can be composed of a label identifier R, a disabling indicator A / D, and a DRX configuration parameter identifier DRX ID. Each DRX ID has a corresponding set of DRX configuration parameters, and each disabling indicator A / D also has a corresponding DRX ID, that is, the disabling indicator can be used to disabling retransmission of the DRX configuration parameter corresponding to the corresponding DRX configuration parameter identifier, so that the DRX indication information can realize the disabling retransmission of the corresponding DRX configuration parameter through the disabling indicator and the DRX configuration parameter identifier, so that the terminal device can reduce the monitoring time and reduce the power consumption of the terminal device.

[0126] In a possible implementation of the first aspect of the present application, the DRX indication information includes at least one disabling indicator and at least one DRX cycle identifier, and the disabling indicator is used to indicate that the DRX cycle corresponding to the corresponding DRX cycle identifier is to be disabling retransmission. As shown in Figure 9, the indication information may be composed of a label identifier R, a disabling indicator A / D, and a DRX cycle identifier cycle ID. Each cycle ID has a corresponding DRX cycle, and each disabling indicator A / D also has a corresponding cycle ID, that is, the disabling indicator can be used to disabling retransmission of the DRX cycle corresponding to the corresponding cycle identifier, so that the DRX indication information can realize the corresponding DRX cycle disabling retransmission through the disabling indicator and the DRX cycle identifier, so that the terminal device can reduce the monitoring time and reduce the power consumption of the terminal device.

[0127] Specifically, the disabling indicator can take a first value or a second value. When the value is the first value, it indicates that retransmission is disabled, and when the value is the second value, it indicates that retransmission is enabled. In the above implementation, the summary method is that one disabling indicator can determine whether to enable or disable retransmission for a set of DRX configuration parameters, a DRX cycle, or a monitoring opportunity; or one disabling indicator can enable or disable retransmission for two or more sets of DRX configuration parameters, or two or more DRX cycles, or two or more monitoring opportunities. For example, one disabling indicator can correspond to two or more sets of DRX configuration parameters, or two or more DRX cycles, or two or more monitoring opportunities; one disabling indicator corresponds to the first and second sets of DRX configuration parameters or two DRX IDs; one disabling indicator corresponds to the first and second DRX cycles or two DRX cycles; one disabling indicator corresponds to the first and second monitoring opportunities or two monitoring opportunities.

[0128] In a possible implementation of an embodiment of the present application, the network device may also construct indication information based on Radio Resource Control (RRC) signaling or Downlink Control Information (DCI) signaling, and the construction method is as described in the above-mentioned embodiment to implement the indication to disable retransmission, so that the terminal device can determine the DRX mechanism that can disable retransmission when communicating according to the DRX configuration parameters, thereby reducing the monitoring time.

[0129] 302. The terminal device receives DRX indication information of discontinuous reception (DRX) from the network device.

[0130] The DRX indication information is used to instruct DRX to enable retransmission or to instruct DRX to disable retransmission.

[0131] In an embodiment of the present application, the network device and the terminal device can communicate with each other, and the network device sends DRX indication information to the terminal device for indicating disabling retransmission or for indicating enabling retransmission, so that the terminal device can receive DRX configuration parameters, so that the terminal device can disable retransmission according to the DRX indication information sent by the network device, reduce the monitoring time, and thus reduce the power consumption of the terminal device.

[0132] In a possible implementation of the embodiment of the present application, step 302, in which the terminal device receives DRX indication information of discontinuous reception (DRX) from the network device, includes:

[0133] B1. Receive DRX from the network device.

[0134] The DRX includes the DRX indication information.

[0135] In an embodiment of the present application, the network device and the terminal device can communicate with each other, the terminal device can receive DRX sent by the network device, and the DRX includes DRX indication information, that is, the DRX can be composed of DRX configuration parameters and DRX indication information, so that the terminal device can extract the DRX indication information from the DRX when receiving the DRX, so that the terminal device can reduce the listening time by disabling retransmission when monitoring according to the DRX indication information and DRX, thereby reducing the power consumption of the terminal device.

[0136] 303. The terminal device monitors according to DRX and DRX indication information.

[0137] In an embodiment of the present application, after receiving the DRX indication information sent by the network device, the terminal device can monitor according to the DRX and DRX indication information.

[0138] When the terminal device meets the data retransmission conditions of the DRX configuration parameters, DRX cycle and monitoring timing for disabling retransmission as indicated by the DRX indication information in the DRX, data retransmission may not be performed, thereby reducing the monitoring time of the terminal device and reducing the power consumption of the terminal device without affecting the content and quality of data transmission. Not retransmitting data can specifically be: disabling the round-trip time timer or disabling the retransmission timer. Disabling the round-trip time timer may include not starting the round-trip time timer or setting the round-trip time timer to infinity; disabling the retransmission timer may include not starting the retransmission timer or setting the retransmission timer to zero.

[0139] When the terminal device meets the data retransmission conditions for enabling retransmission, including the DRX configuration parameters, DRX cycle, and monitoring timing indicated by the DRX indication information in the DRX, data retransmission can be initiated to ensure the content and quality of the data transmission. Specifically, data retransmission can be performed by enabling a round-trip timer or enabling a retransmission timer. Enabling a round-trip timer may include starting a round-trip timer; enabling a retransmission timer may include starting a retransmission timer.

[0140] The above-mentioned retransmission conditions include: monitoring data scheduling at the activation time corresponding to DRX, for example, monitoring data scheduling at the monitoring time corresponding to the duration timer or the monitoring time corresponding to the inactivation timer, for example, monitoring PDCCH or physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) or physical uplink shared channel (Physical Uplink Shared Channel, PUSCH).

[0141] In the embodiment of the present application, the DRX indication information may indicate disabling of uplink retransmission or disabling of downlink retransmission.

[0142] Specifically, as shown in FIG4 above, when DRX includes one or more sets of DRX configuration parameters, such as DRX1 and DRX2, the terminal device can determine the DRX configuration parameters that can disable retransmission from DRX according to the DRX indication information, such as DRX2. And when the terminal device meets the retransmission activation conditions corresponding to DRX2, for example, when data is monitored at the activation time corresponding to DRX2, DRX2 retransmission scheduling may not be performed, and the terminal device can complete data retransmission within the monitoring time of the next cycle of DRX2, thereby reducing the monitoring time of the terminal device and reducing the power consumption of the terminal device without affecting the data transmission content and quality.

[0143] When the DRX indication information includes the first indication, and the first indication is used to indicate whether DRX2 disables retransmission, it may specifically be:

[0144] When the first indication is used to indicate enabling retransmission, a round trip timer may be started when data is monitored during the activation time corresponding to DRX2.

[0145] When the first indication is used to indicate disabling retransmission, when data is monitored at the activation time corresponding to DRX2, the round-trip time timer is not started; or the round-trip time timer is turned on, and the activation duration of the round-trip time timer is set to infinity; or the round-trip time timer is turned on, and the activation duration of the retransmission timer is set to zero.

[0146] Specifically, since the terminal device can be divided into the transmission of uplink data and the reception of downlink data when transmitting multimodal service data, when the data transmitted by the terminal device is uplink data, when the first indication is used to indicate the enabling of retransmission, for example, the uplink data network monitored at the monitoring period corresponding to the DRX2 will schedule retransmission, and when retransmission needs to be enabled, the uplink round-trip time timer can be started when the uplink data is monitored at the activation time corresponding to the DRX2.

[0147] When the data transmitted by the terminal device is uplink data, and when the first indication is used to indicate disabling retransmission, for example, the uplink data network monitored at the monitoring period corresponding to the DRX2 will not schedule retransmission, and retransmission needs to be disabled, then when uplink data is monitored at the activation time corresponding to the DRX2, the uplink round-trip time timer is not turned on; or the uplink round-trip time timer is turned on, and the activation duration of the uplink round-trip time timer is set to infinity; or the uplink round-trip time timer is turned on, and the activation duration of the uplink retransmission timer is set to zero.

[0148] When the data received by the terminal device is downlink data, when the first indication is used to indicate enabling retransmission, for example, the data monitored at the monitoring period corresponding to the DRX2 can be HARQ feedback, then when downlink data is monitored at the activation time corresponding to the DRX2, if a negative acknowledgment (Negative-Acknowledgment, NACK) is returned, the downlink round-trip time timer can be started.

[0149] When the data received by the terminal device is downlink data, when the first indication is used to indicate disabling retransmission, for example, the data monitored at the monitoring period corresponding to the DRX2 cannot be HARQ feedback, then when downlink data is monitored at the activation time corresponding to the DRX2, no HARQ feedback will be performed and the downlink round-trip time timer will not be turned on; or the downlink round-trip time timer will be turned on and the activation duration of the downlink round-trip time timer will be set to infinity; or the downlink round-trip time timer will be turned on and the activation duration of the downlink retransmission timer will be set to zero.

[0150] As shown in FIG5 , when DRX includes one or more DRX cycles, such as cycle 1 and cycle 2, the terminal device can determine from DRX the DRX cycle in which retransmission can be disabled, such as cycle 2, based on the DRX indication information. When the terminal device meets the retransmission activation condition corresponding to cycle 2, for example, when data is monitored during the activation time corresponding to cycle 2, the retransmission scheduling of cycle 2 can be canceled, and data retransmission can be completed during the monitoring time of the next cycle of cycle 2. This can reduce the monitoring time of the terminal device and reduce the power consumption of the terminal device without affecting the data transmission content and quality.

[0151] When the DRX indication information includes the first indication, and the first indication is used to indicate whether to disable retransmission in cycle 2, it may specifically be:

[0152] When the first indication is used to indicate enabling retransmission, if data is monitored during the activation time corresponding to period 2, a round trip timer may be started.

[0153] When the first indication is used to indicate disabling retransmission, if data is monitored at the activation time corresponding to period 2, the round-trip time timer is not started; or the round-trip time timer is turned on, and the activation duration of the round-trip time timer is set to infinity; or the round-trip time timer is turned on, and the activation duration of the retransmission timer is set to zero.

[0154] Specifically, since the terminal device can be divided into the transmission of uplink data and the reception of downlink data when transmitting multimodal service data, when the data transmitted by the terminal device is uplink data, when the first indication is used to indicate the enabling of retransmission, for example, the uplink data network monitored at the monitoring opportunity corresponding to period 2 will schedule retransmission, and when retransmission needs to be enabled, the uplink round-trip time timer can be started when the uplink data is monitored at the activation time corresponding to period 2.

[0155] When the data transmitted by the terminal device is uplink data, when the first indication is used to indicate disabling retransmission, for example, the uplink data network monitored at the monitoring time corresponding to period 2 will not schedule retransmission, and retransmission needs to be disabled, then when uplink data is monitored at the activation time corresponding to period 2, the uplink round-trip time timer is not turned on; or the uplink round-trip time timer is turned on, and the activation duration of the uplink round-trip time timer is set to infinity; or the uplink round-trip time timer is turned on, and the activation duration of the uplink retransmission timer is set to zero.

[0156] When the data received by the terminal device is downlink data, when the first indication is used to indicate enabling retransmission, for example, the data monitored at the monitoring opportunity corresponding to cycle 2 can be HARQ feedback, then when downlink data is monitored at the activation time corresponding to cycle 2, if NACK is returned, the downlink round-trip time timer can be started.

[0157] When the data received by the terminal device is downlink data, when the first indication is used to indicate disabling retransmission, for example, the data monitored at the monitoring opportunity corresponding to cycle 2 cannot be HARQ feedback, then when downlink data is monitored at the activation time corresponding to cycle 2, no HARQ feedback will be performed and the downlink round-trip time timer will not be turned on; or the downlink round-trip time timer will be turned on, and the activation duration of the downlink round-trip time timer will be set to infinity; or the downlink round-trip time timer will be turned on, and the activation duration of the downlink retransmission timer will be set to zero.

[0158] As shown in FIG6 above, when a DRX cycle includes one or more monitoring opportunities, such as three monitoring opportunities in cycle 1, the terminal device can determine the monitoring opportunities for disabling retransmission from DRX according to the DRX indication information, such as the second monitoring opportunity and the third monitoring opportunity in cycle 1. And when the terminal device meets the retransmission activation conditions corresponding to the second monitoring opportunity and the third monitoring opportunity in cycle 1, for example, when data is monitored at the second monitoring opportunity and the third monitoring opportunity in cycle 1, the retransmission scheduling of the second monitoring opportunity and the third monitoring opportunity in cycle 1 can be canceled, and the data retransmission can be completed in the first monitoring opportunity of the next cycle of cycle 1, thereby reducing the monitoring time of the terminal device and reducing the power consumption of the terminal device without affecting the data transmission content and quality.

[0159] When the DRX indication information includes the first indication, and the first indication is used to indicate whether to disable retransmission at the monitoring opportunity, it may specifically be:

[0160] When the first indication is used to indicate enabling retransmission, a round trip timer may be started when data is monitored at the activation time corresponding to the monitoring opportunity.

[0161] When the first indication is used to indicate disabling retransmission, when data is monitored at the activation time corresponding to the monitoring opportunity, the round-trip time timer is not started; or the round-trip time timer is turned on, and the activation duration of the round-trip time timer is set to infinity; or the round-trip time timer is turned on, and the activation duration of the retransmission timer is set to zero.

[0162] Specifically, since the terminal device can be divided into the transmission of uplink data and the reception of downlink data when transmitting multimodal service data, when the data transmitted by the terminal device is uplink data, when the first indication is used to indicate enabling retransmission, for example, the uplink data network monitored at the monitoring timing corresponding to the monitoring timing will schedule retransmission, and when retransmission needs to be enabled, the uplink round-trip time timer can be started when uplink data is monitored at the activation time corresponding to the monitoring timing.

[0163] When the data transmitted by the terminal device is uplink data, when the first indication is used to indicate disabling retransmission, for example, the uplink data network monitored at the monitoring timing corresponding to the monitoring timing will not schedule retransmission, and retransmission needs to be disabled, then when uplink data is monitored at the activation time corresponding to the monitoring timing, the uplink round-trip time timer is not turned on; or the uplink round-trip time timer is turned on, and the activation duration of the uplink round-trip time timer is set to infinity; or the uplink round-trip time timer is turned on, and the activation duration of the uplink retransmission timer is set to zero.

[0164] When the data received by the terminal device is downlink data, when the first indication is used to indicate enabling retransmission, for example, the data monitored at the activation time corresponding to the monitoring opportunity can be HARQ feedback, then when downlink data is monitored at the activation time corresponding to the monitoring opportunity, if NACK is returned, the downlink round-trip time timer can be started.

[0165] When the data received by the terminal device is downlink data, when the first indication is used to indicate disabling retransmission, for example, the data monitored at the activation time corresponding to the monitoring opportunity cannot be HARQ feedback, then when downlink data is monitored at the activation time corresponding to the monitoring opportunity, no HARQ feedback will be performed and the downlink round-trip time timer will not be started; or the downlink round-trip time timer will be turned on, and the activation duration of the downlink round-trip time timer will be set to infinity; or the downlink round-trip time timer will be turned on, and the activation duration of the downlink retransmission timer will be set to zero.

[0166] In a possible implementation of an embodiment of the present application, when the DRX indication information includes a second indication, the monitoring according to the DRX and the DRX indication information includes: determining a target monitoring time for disabling retransmission from the DRX according to the DRX indication information; and turning off a round-trip time timer corresponding to the target monitoring time. In the process of monitoring according to the DRX and the DRX indication information, the terminal device may first determine a target monitoring time for disabling retransmission from the DRX according to the DRX indication information, wherein the target monitoring time may include a monitoring time corresponding to at least one set of DRX configuration parameters in the DRX, or may include a monitoring time corresponding to at least one DRX cycle in the DRX, or may include at least one monitoring time in a cycle in the DRX. When the terminal device meets the retransmission activation condition corresponding to the target monitoring time, the retransmission may be disabling by turning off the round-trip time timer so that the retransmission timer cannot be triggered, thereby reducing the monitoring time of the terminal device and reducing the power consumption of the terminal device.

[0167] Specifically, since the terminal device can be divided into the transmission of uplink data and the reception of downlink data when transmitting multimodal service data, when the data transmitted by the terminal device is uplink data, the terminal device can disable retransmission of the uplink data by turning off the uplink round-trip time timer when the retransmission activation condition corresponding to the target monitoring timing is met, so that the uplink retransmission timer cannot be triggered. When the data received by the terminal device is downlink data, when the terminal device monitors downlink data at the monitoring time corresponding to the DRX mechanism that can disable retransmission, the downlink retransmission timer can be turned off to disable retransmission of the downlink data.

[0168] In a possible implementation of an embodiment of the present application, when the DRX indication information includes a third indication, the monitoring according to the DRX and the DRX indication information includes: determining a target monitoring opportunity for retransmission to be disabled from the DRX according to the DRX indication information; and setting a value of a round-trip time timer corresponding to the target monitoring opportunity to infinity. In the process of monitoring according to the DRX and the DRX indication information, the terminal device may first determine a target monitoring opportunity for retransmission to be disabled from the DRX according to the DRX indication information, wherein the target monitoring opportunity may include a monitoring opportunity corresponding to at least one set of DRX configuration parameters in the DRX, or may include a monitoring opportunity corresponding to at least one DRX cycle in the DRX, or may include at least one monitoring opportunity in a cycle in the DRX. When the terminal device meets the retransmission activation condition corresponding to the target monitoring opportunity, the disabling of retransmission may be achieved by turning on the round-trip time timer and setting the activation duration of the round-trip time timer to infinity, so that the terminal device will always turn on the round-trip time timer, and the retransmission timer cannot be triggered, thereby reducing the monitoring time of the retransmission timer during data transmission, thereby reducing the monitoring time of the terminal device and reducing the power consumption of the terminal device.

[0169] Specifically, since the terminal device can be divided into the transmission of uplink data and the reception of downlink data when transmitting multimodal service data, when the data transmitted by the terminal device is uplink data, the terminal device can disable retransmission by turning on the uplink round-trip time timer and setting the activation duration of the uplink round-trip time timer to infinity when the retransmission activation condition corresponding to the target listening opportunity is met, so that the uplink round-trip time timer is always on and the uplink retransmission timer cannot be triggered. When the data received by the terminal device is downlink data, the terminal device can disable retransmission by turning on the downlink round-trip time timer and setting the activation duration of the downlink round-trip time timer to infinity when the retransmission activation condition corresponding to the target listening opportunity is met, so that the downlink round-trip time timer is always on and the downlink retransmission timer cannot be triggered.

[0170] In a possible implementation of an embodiment of the present application, when the DRX indication information includes a fourth indication, the monitoring according to the DRX and the DRX indication information includes: determining a target monitoring timing for retransmission to be disabled from the DRX according to the DRX indication information; and setting the value of the retransmission timer corresponding to the target monitoring timing to zero. In the process of monitoring according to the DRX and the DRX indication information, the terminal device may first determine a target monitoring timing for retransmission to be disabled from the DRX according to the DRX indication information, wherein the target monitoring timing may include a monitoring timing corresponding to at least one set of DRX configuration parameters in the DRX, or may include a monitoring timing corresponding to at least one DRX cycle in the DRX, or may include at least one monitoring timing in a cycle in the DRX. When the terminal device meets the retransmission activation conditions corresponding to the target listening opportunity, retransmission can be disabled by turning on the round-trip time timer and setting the activation duration of the retransmission timer to zero, so that the terminal device will turn on the round-trip time timer. However, when the listening time of the round-trip time timer ends, the retransmission timer cannot be triggered because the activation duration of the retransmission timer is zero, which reduces the listening time of the retransmission timer during data transmission, thereby reducing the listening time of the terminal device and reducing the power consumption of the terminal device.

[0171] Specifically, since the terminal device can be divided into the transmission of uplink data and the reception of downlink data when transmitting multimodal service data, when the data transmitted by the terminal device is uplink data, the terminal device can disable retransmission by turning on the uplink round-trip time timer and setting the activation duration of the uplink retransmission timer to zero when the retransmission activation condition corresponding to the target listening opportunity is met, so that when the listening time of the uplink round-trip time timer ends, the uplink retransmission timer cannot be triggered because the activation duration of the uplink retransmission timer is zero. When the data received by the terminal device is downlink data, the terminal can disable retransmission by turning on the downlink round-trip time timer and setting the activation duration of the downlink retransmission timer to zero when the retransmission activation condition corresponding to the target listening opportunity is met, so that when the listening time of the downlink round-trip time timer ends, the downlink retransmission timer cannot be triggered because the activation duration of the downlink retransmission timer is zero.

[0172] It can be seen from the examples of the aforementioned embodiments that compared with the prior art that directly configures and sends multiple sets of DRX configuration parameters to the terminal device, which may cause the terminal device to listen for too long, in order to reduce the listening time of the terminal device and reduce the power consumption of the terminal device, the network device can send DRX indication information to the terminal device for indicating that DRX enables retransmission or for indicating that DRX disables retransmission, so that the terminal device can disable DRX retransmission according to the DRX indication information sent by the network device, thereby reducing the terminal device listening time and thus reducing the power consumption of the terminal device.

[0173] In order to make the technical solution of the present application clearer and easier to understand, the communication method of the present application is explained below in conjunction with a specific data transmission scenario of a terminal device and a network device.

[0174] First, referring to a schematic diagram of data transmission between a terminal device and a network device shown in FIG10a , the method includes the following steps:

[0175] S01. The gNB sends a DRX signal that disables retransmission to the UE.

[0176] The DRX for disabling retransmission includes DRX configuration parameters for disabling retransmission.

[0177] In this embodiment of the present application, the DRX signal sent by the gNB to the UE may include a DRX signal that disables retransmission. The DRX configuration parameters for disabling retransmission may be DRX configuration parameters pre-configured by the gNB. For the DRX configuration parameters or DRX cycle that require disabling retransmission, the gNB may directly not configure the corresponding round trip timer and retransmission timer in the DRX configuration parameters, or may include DRX indication information in the DRX signal, so that after the gNB sends the DRX signal to the UE, if the UE monitors data within the DRX monitoring time, retransmission scheduling may not be performed, thereby reducing the UE's monitoring time and the UE's transmission power consumption.

[0178] Next, referring to another schematic diagram of data transmission between a terminal device and a network device shown in FIG10b , the method includes the following steps:

[0179] S11. The gNB sends the DRX function that disables retransmission to the UE.

[0180] The DRX configured to disable retransmission includes DRX configuration parameters for disabling retransmission.

[0181] In this embodiment of the present application, the DRX information sent by the gNB to the UE may include DRX information that disables retransmission. The DRX configuration parameters that disable retransmission may be DRX configuration parameters pre-configured by the gNB. For DRX configuration parameters or DRX cycles that require disabling retransmission, the gNB may not configure the corresponding round trip timer and retransmission timer in the DRX configuration parameters, or may include DRX indication information in the DRX information.

[0182] S12. The gNB sends DRX indication information to the UE.

[0183] The DRX indication information is used to indicate whether DRX enables or disables retransmission.

[0184] In an embodiment of the present application, after the gNB sends a DRX to disable retransmission to the UE, it can continue to send DRX indication information to the UE, so that during the data transmission process, the UE can disable retransmission according to the listening opportunity for disabling retransmission indicated by the DRX indication information, or enable retransmission for the listening opportunity for enabling retransmission indicated by the DRX indication information, thereby reducing the UE's listening time and reducing the UE's transmission power consumption.

[0185] Finally, referring to another schematic diagram of data transmission between a terminal device and a network device shown in FIG10c , the method includes the following steps:

[0186] S21. The gNB sends DRX to the UE.

[0187] In the embodiment of the present application, when configuring a new DRX, the gNB may directly configure the DRX by using the common parameters of the DRX configuration parameters in other DRXs. That is, when the gNB configures a new DRX, the configured DRX may include only the DRX configuration parameters that need to enable retransmission.

[0188] S22. The gNB sends DRX indication information to the UE.

[0189] The DRX indication information is used to indicate whether DRX enables or disables retransmission.

[0190] In an embodiment of the present application, after sending the configured DRX to the UE, the gNB may continue to send DRX indication information to the UE, for indicating that the DRX configuration parameters that can be disabled for retransmission in the configured DRX are disabled for retransmission, so that the UE can disable retransmission of the configuration parameters that can be disabled for retransmission indicated by the DRX indication information during data transmission, thereby reducing the UE's monitoring time and reducing the UE's transmission power consumption.

[0191] It should be noted that the above embodiments are merely some illustrative implementation methods provided by this application, and it does not mean that this application only provides the above methods. In actual applications, the steps of the above embodiments can also be split or combined, and this application does not limit this.
