Description

A communication method, communication device and storage medium

[0001] This application claims priority to Chinese Patent Application No. 202410310561.5, filed on March 18, 2024, entitled "A Communication Method, Communication Device and Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

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

[0003] Multimodal extended reality devices refer to devices that perform multimodal services. A multimodal service may include data of multiple service types, and this data may come from a terminal device, a terminal device that connects one or more devices, or multiple terminal devices.

[0004] When terminal devices transmit data, they typically need to use Discontinuous Reception (DRX) to save power, and different types of data usually require different DRX configurations. Therefore, when transmitting multimodal services, terminal devices usually need to be configured with multiple sets of DRX configuration parameters.

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

[0006] This application provides a communication method, a communication device, and a storage medium, with the aim of reducing the power consumption of terminal devices.

[0007] To achieve the above objectives, this application provides the following technical solution:

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

[0009] The DRX indication information for discontinuous DRX reception is sent to the terminal device. The DRX indication information is used to indicate whether DRX retransmission is enabled or disabled.

[0010] In the above implementation scheme, compared with the existing technology that directly configures and sends multiple sets of DRX configuration parameters to the terminal device, which may lead to excessively long listening time for the terminal device, 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 to indicate whether to enable or disable DRX retransmission. This allows the terminal device to disable and retransmit DRX according to the DRX indication information sent by the network device, thereby reducing the listening time of the terminal device and thus reducing the power consumption of the terminal device.

[0011] In one possible implementation of the first aspect of this application, sending the DRX indication information of the discontinuously received DRX to the terminal device includes: sending the 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 to the DRX to indicate whether to enable or disable retransmission, so that when the terminal device receives the DRX, it can directly disable retransmission based on the DRX indication information in the DRX, thereby reducing the terminal device's listening time and power consumption.

[0012] In one possible implementation of the first aspect of this application, the DRX indication information is used to instruct at least one set of DRX configuration parameters in the DRX to enable retransmission. In the above implementation, the DRX sent by the network device to the terminal device may include one or more sets of DRX configuration parameters. The DRX indication information can be used to enable retransmission of at least one set of DRX configuration parameters, allowing the terminal device to reduce listening time and power consumption by disabling retransmission of at least one set of DRX configuration parameters during monitoring.

[0013] In one possible implementation of the first aspect of this application, the DRX indication information is used to instruct at least one DRX cycle in the DRX to enable retransmission. In the above implementation, the DRX sent by the network device to the terminal device may include one or more DRX cycles. The DRX indication information can be used to enable retransmission of at least one DRX cycle in the DRX, so that the terminal device can reduce the listening time and reduce the power consumption of the terminal device by enabling retransmission of at least one DRX cycle when listening.

[0014] In one possible implementation of the first aspect of this application, the DRX indication information is used to indicate at least one listening opportunity in a DRX cycle to enable retransmission. In the above implementation, a DRX cycle sent by the network device to the terminal device may include one or more listening opportunities. The DRX indication information can be used to enable retransmission for at least one listening opportunity in a DRX cycle, allowing the terminal device to reduce listening time and power consumption by disabling retransmission for at least one listening opportunity during listening.

[0015] In one possible implementation of the first aspect of this 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 retransmission to be disabled; the second indication is used to instruct the round-trip time timer to be turned off; the third indication is used to instruct the round-trip time timer to be set to infinity; and the fourth indication is used to instruct the retransmission timer to be set to zero. In the above implementation, the DRX indication information sent by the network device to the terminal device can directly instruct retransmission to be disabled, or it can be implemented by instructing the round-trip time timer to be turned off, or by instructing the round-trip time timer to be set to infinity, or by instructing the retransmission timer to be set to zero.

[0016] In one possible implementation of the first aspect of this application, the round-trip time timer includes at least one of an uplink round-trip time timer and a downlink round-trip time timer; the retransmission timer includes at least one of an uplink retransmission time timer and a downlink retransmission time timer. In the above implementation, since the terminal device can transmit multimodal service data in two ways—uplink data transmission and downlink data reception—the DRX indication information sent by the network device to the terminal device can enable retransmission by indicating the value of at least one of the uplink and downlink round-trip time timers, or by indicating the value of at least one of the uplink and downlink retransmission time timers. This can precisely reduce the terminal device's listening time and lower its power consumption.

[0017] In one possible implementation of the first aspect of this application, the DRX indication information includes at least one disable indicator. The disable indicator is used to indicate that the DRX configuration parameter corresponding to the position of the disable indicator is disabled for retransmission. The position of the disable indicator corresponds to the configuration order of the DRX configuration parameters. In the above implementation, the DRX indication information may include a disable indicator, and the position of the disable indicator corresponds to the configuration order of the DRX configuration parameters. This allows the DRX indication information to disable retransmission of the corresponding DRX configuration parameter through the disable indicator, thereby reducing the listening time and power consumption of the terminal device.

[0018] In one possible implementation of the first aspect of this application, the DRX indication information includes at least one disable indicator. The disable indicator is used to indicate that retransmission is disabled in the DRX cycle corresponding to the position of the disable indicator. The position of the disable indicator corresponds to the configuration order of the DRX cycles. In the above implementation, the DRX indication information may include a disable indicator, and the position of the disable indicator corresponds to the configuration order of the DRX cycles. This allows the DRX indication information to enable retransmission in the corresponding DRX cycle through the disable indicator, thereby reducing the listening time and power consumption of the terminal device.

[0019] In one possible implementation of the first aspect of this application, the DRX indication information includes at least one disable indicator. The disable indicator is used to indicate whether retransmission is enabled at the listening time corresponding to the position of the disable indicator. The position of the disable indicator corresponds to the configuration order of the listening times. In the above implementation, the DRX indication information may include a disable indicator, and the position of the disable indicator corresponds to the configuration order of the listening times. This allows the DRX indication information to disable retransmission at the corresponding listening time through the disable indicator, thereby reducing the listening time and power consumption of the terminal device.

[0020] In one possible implementation of the first aspect of this application, the DRX indication information includes at least one disable indicator and at least one DRX configuration parameter identifier. The disable indicator is used to indicate that the DRX configuration parameter corresponding to the corresponding DRX configuration parameter identifier is disabled for retransmission. In the above implementation, the DRX indication information may include a disable indicator and a DRX configuration parameter identifier, and each DRX configuration parameter identifier corresponds to a set of DRX configuration parameters. One disable indicator corresponds to one DRX configuration parameter identifier, so that the DRX indication information can enable the disabling and retransmission of the corresponding DRX configuration parameters through the disable indicator and the DRX configuration parameter identifier, thereby reducing the listening time and power consumption of the terminal device.

[0021] In one possible implementation of the first aspect of this application, the DRX indication information includes at least one disable indicator and at least one DRX cycle identifier. The disable indicator is used to indicate that the DRX cycle corresponding to the corresponding DRX cycle identifier is disabled for retransmission. In the above implementation, the DRX indication information may include a disable indicator and a DRX cycle identifier, and each DRX cycle identifier corresponds to one DRX cycle. One disable indicator corresponds to one DRX cycle identifier, so that the DRX indication information can enable the disabling and retransmission of the corresponding DRX configuration parameters through the disable indicator and the DRX cycle identifier, thereby reducing the listening time and power consumption of the terminal device.

[0022] A second aspect of this application provides a communication method applied to a terminal device. The method includes: receiving DRX indication information from a network device for discontinuously received DRX, wherein the DRX indication information is used to indicate whether DRX retransmission is enabled or disabled; and listening based on the DRX and the DRX indication information. In the above implementation, compared to the prior art where the terminal device directly listens based on multiple sets of DRX parameters sent by the network device, which may lead to excessively long listening time, in order to reduce the listening time and power consumption of the terminal device, the terminal device can receive DRX indication information sent by the network device to indicate whether retransmission is disabled. This allows the terminal device to disable retransmission based on the DRX indication information sent by the network device, reducing listening time and thus reducing the power consumption of the terminal device.

[0023] In one possible implementation of the second aspect of this application, receiving DRX indication information from a network device for discontinuous DRX reception includes:

[0024] Receive DRX from a network device, the DRX including the DRX indication information.

[0025] In one possible implementation of the second aspect of this application, the DRX indication information is used to instruct at least one set of DRX configuration parameters in the DRX to enable retransmission.

[0026] In one possible implementation of the second aspect of this application, the DRX indication information is used to indicate at least one DRX cycle in the DRX to enable retransmission.

[0027] In one possible implementation of the second aspect of this application, the DRX indication information is used to indicate at least one listening opportunity in a DRX cycle to enable retransmission.

[0028] In one possible implementation of the second aspect of this application, when the DRX indication information is used to instruct the 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 retransmission to be disabled; the second indication is used to instruct the round-trip time timer to be turned off; the third indication is used to instruct the round-trip time timer to be set to infinity; and the fourth indication is used to instruct the retransmission timer to be set to zero.

[0029] In one possible implementation of the second aspect of this application, the round-trip time timer includes at least one of an uplink round-trip time timer and a downlink round-trip time timer; the retransmission timer includes at least one of an uplink retransmission time timer and a downlink retransmission time timer.

[0030] In one possible implementation of the second aspect of this application, the DRX indication information includes at least one de-enable indicator, which is used to indicate that the DRX configuration parameter corresponding to the position of the de-enable indicator is de-enabled for retransmission, and the position of the de-enable indicator corresponds to the configuration order of the DRX configuration parameters.

[0031] In one possible implementation of the second aspect of this application, the DRX indication information includes at least one de-enable indicator, which is used to indicate that the DRX cycle corresponding to the position of the de-enable indicator is de-enabled for retransmission, and the position of the de-enable indicator corresponds to the configuration order of the DRX cycles.

[0032] In one possible implementation of the second aspect of this application, the DRX indication information includes at least one de-enable indicator, which is used to indicate the listening timing corresponding to the position of the de-enable indicator to enable retransmission, and the position of the de-enable indicator corresponds to the configuration order of the listening timing.

[0033] In one possible implementation of the second aspect of this application, the DRX indication information includes at least one de-enable indicator and at least one DRX configuration parameter identifier, wherein the de-enable indicator is used to indicate that the DRX configuration parameter corresponding to the corresponding DRX configuration parameter identifier is de-enabled for retransmission.

[0034] In one possible implementation of the second aspect of this application, the DRX indication information includes at least one de-enable indicator and at least one DRX cycle identifier, wherein the de-enable indicator is used to indicate that the DRX cycle corresponding to the corresponding DRX cycle identifier is de-enabled for retransmission.

[0035] In one possible implementation of the second aspect of this application, when the DRX indication information includes a second indication, the step of monitoring based on the DRX and the DRX indication information includes: determining a target monitoring opportunity to disable retransmission from the DRX based on the DRX indication information; and disabling the round-trip timer corresponding to the target monitoring opportunity. In the above implementation, when the terminal device meets the retransmission activation condition corresponding to the target monitoring opportunity, disabling the retransmission timer can prevent the retransmission timer from being triggered, thereby reducing the monitoring time of the terminal device and lowering its power consumption.

[0036] In one possible implementation of the second aspect of this application, when the DRX indication information includes a third indication, the step of monitoring based on the DRX and the DRX indication information includes: determining the target monitoring timing to be deenabled for retransmission from the DRX based on the DRX indication information; and setting the value of the round-trip timer corresponding to the target monitoring timing to infinity. In the above implementation, when the terminal device meets the retransmission activation condition corresponding to the target monitoring timing, deenabled retransmission can be achieved by enabling the round-trip timer and setting its activation duration to infinity. This ensures that the terminal device always keeps the round-trip timer active, preventing the retransmission timer from being triggered, thus reducing the monitoring time of the retransmission timer during data transmission, thereby reducing the monitoring time of the terminal device and lowering its power consumption.

[0037] In one possible implementation of the second aspect of this application, when the DRX indication information includes a fourth indication, the step of listening based on the DRX and the DRX indication information includes: determining the target listening opportunity to disable retransmission from the DRX based on the DRX indication information; and setting the value of the retransmission timer corresponding to the target listening opportunity to zero. In the above implementation, when the terminal device meets the retransmission activation condition corresponding to the target listening opportunity, retransmission can be disabled by enabling the round-trip timer and setting the activation duration of the retransmission timer to zero. This causes the terminal device to activate the round-trip timer. However, when the listening time of the round-trip timer ends, since the activation duration of the retransmission timer is zero, the retransmission timer cannot be triggered, reducing 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.

[0041] The receiving module is used to receive DRX indication information from the network device for discontinuous DRX reception. The DRX indication information is used to indicate whether to enable DRX retransmission or to indicate whether to disable DRX retransmission.

[0042] The monitoring module is used to monitor according to the DRX and the DRX indication information.

[0064] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The terminology used in the following embodiments is for the purpose of describing specific embodiments only and is not intended to be a limitation of this application. As used in the specification and appended claims of this application, the singular expressions "a," "an," "the," "the," "the," and "this" are intended to also include expressions such as "one or more," unless the context clearly indicates otherwise. It should also be understood that in the embodiments of this application, "one or more" refers to one, two, or more; "and / or" describes the relationship between related objects, indicating that three relationships may exist; for example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0065] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of 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 "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0066] The "multiple" mentioned in the embodiments of this application refers to two or more. It should be noted that in the description of the embodiments of this application, terms such as "first" and "second" are used only for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance, nor should they be construed as indicating or implying order.

[0067] The embodiments of this application are applied to communication systems, which can 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 will emerge in the future development of communication.

[0068] The communication system includes a first device and a second device. The first device can be a network-side device used to provide network communication functions; in some cases, it is also called a network device or network element. The network device can typically be a base station (including functional units of a base station, or a combination of functional units of base stations) or a core network unit. The core network unit can be a functional unit within the core network, including but not limited to Access and Mobility Management Function (AMF) units or Session Management Function (SMF) units. The second device can be a device accessing the network, typically 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 this application, the base station can be any device with wireless transceiver capabilities, including but not limited to: evolved base stations (NodeB, eNB, or e-NodeB) in Long Term Evolution (LTE), base stations (gNodeB or gNB) or transmission receiving points / transmission reception points (TRPs) in New Radio (NR), base stations in subsequent 3GPP evolutions, access nodes in Wi-Fi systems, wireless relay nodes, wireless backhaul nodes, etc. The base station can be: macro base station, micro base station, pico base station, small cell, relay station, or balloon station, etc. The base station can include one or more co-located or non-co-located Transmission Reception Points (TRPs). The base station can also be a radio controller, centralized unit (CU), and / or distributed unit (DU) in a cloud radio access network (CRAN) scenario. The base station can communicate with terminal devices or communicate with terminal devices through relay stations. Terminal devices can communicate with multiple base stations using different technologies. For example, a terminal device can communicate with a base station that supports LTE networks, or with a base station that supports 5G networks, or even have dual connections with both LTE and 5G base stations.

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

[0071] In communication systems, extended reality (XR) devices can include two scenarios: one is that the multimodal XR device can be a single terminal, with one terminal generating a multimodal service that includes multiple data streams; the other is that the multimodal XR device can be multiple terminals, with each terminal generating several data streams, and a multimodal service consisting of multiple data streams generated by multiple terminals.

[0072] The multimodal service in this application embodiment consists of several interrelated data streams, which can also be referred to as multimodal streams. These data streams may originate from different sources. A data stream can be called unimodal data, and a data stream can be considered as a type of data associated with the same communication service. For example, the data streams in this application embodiment may be audio data, video data, location data, and haptic data. The data streams of the multimodal service may originate from a single UE, or be transmitted via a single device, or via multiple devices connected to a single UE that can access the communication system, or originate from multiple UEs.

[0073] In this application embodiment, the requirements for multimodal services refer to the service requirements of multimodal services, such as the quality of service (QoS) monitoring requirements for multiple Internet Protocol (IP) data streams related to multimodal services.

[0074] The Discontinuous Reception (DRX) method in this application embodiment is a method for optimizing energy efficiency at the link layer of a wireless communication system. It allows a terminal device to shut down its wireless transceiver unit without data transmission, thus entering a low-power state. This mechanism is crucial for improving the energy efficiency and quality of service in mobile communication systems because it can maximize the battery life of the user terminal 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 for which monitoring is required at the start of the DRX cycle.

[0076] Inactive Timer: This refers to the duration for which listening is required after the Physical Downlink Control Channel (PDCCH) indicates that new data needs to be transmitted.

[0077] Round-Trip Time (RTT) timers can be divided into uplink RTT timers (HARQ RTT Timer UL) and downlink RTT timers (HARQ RTT Timer DL). The uplink RTT timer refers to the minimum time required to receive an uplink Hybrid Automatic Repeat reQuest (HARQ) retransmission. The downlink RTT timer refers to the minimum time required to receive a downlink HARQ retransmission allocation message.

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

[0079] To make the technical solution of this application clearer, the DRX configuration parameters will be described in detail below:

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

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

[0082] Drx-Inactivity Timer: PDCCH indicates the duration following a PDCCH timing event for a new uplink (UL), downlink (DL), or signaling link (SL) transmission by a Medium Access Control (MAC) entity.

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

[0084] Drx-Retransmission Timer UL (per UL HARQ process): The maximum duration before a UL retransmission authorization is received;

[0085] Drx-Long Cycle Start Offset: The drx-Start Offset for the start of the long DRX cycle and the cycle start subframes that define the long and short DRX cycles;

[0086] Drx-Non Integer Long Cycle Start Offset (optional): When the lengths of the long DRX cycle and / or the short DRX cycle are not integers, the long DRX cycle and drx-StartOffset define the subframe at which the long and short DRX cycles begin;

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

[0088] Drx-Non Integer Short Cycle (Optional): Short DRX cycles with a length that is not an integer;

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

[0090] Drx-HARQ RTT Timer DL (for each DL HARQ process except the broadcast process): The minimum duration expected by the MAC entity before the DL allocation for HARQ retransmission;

[0091] Drx-HARQ RTT Timer UL (per UL HARQ process): The minimum duration that a MAC entity expects before UL HARQ retransmission authorization;

[0092] Drx-Last Transmission UL (optional): Configures the Drx-HARQ RTT Timer UL to start after the last transmission within the bundle;

[0093] PS wake-up (optional): If the Digital Communication Protocol (DCP) is monitored but not detected, start the configuration of the relevant Drx-on Duration Timer;

[0094] Download HARQ Feedback Disabled (Optional): Configuration that disables HARQ feedback for each DL HARQ process;

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

[0096] Disable CG Retransmission Monitoring (optional): Disables the configuration to start Drx-HARQ RTT Timer UL for UL transmission on the configured uplink license;

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

[0098] When terminal devices transmit data, they typically employ DRX (Digital Replication) to save power, and different types of data usually require different DRX configurations. Therefore, when transmitting multimodal service data, which often includes multiple service types, network devices need to configure multiple sets of DRX parameters for the terminal device. However, configuring multiple sets of DRX parameters for the terminal device can lead to dense listening times in the time domain because the listening times for each set may differ.

[0099] The specific process of data retransmission during data transmission by a terminal device typically involves activating a round-trip timer when data is detected during the listening time of an inactive timer, activating a retransmission timer after the listening time of the round-trip timer ends, and finally completing the data retransmission scheduling within the listening time of the retransmission timer. Therefore, if data retransmission is allowed for every listening time, the terminal device requires more listening time to transmit or receive data, potentially leading to excessively long listening times and ultimately failing to achieve the goal of power saving. This application provides a communication method that reduces the listening time of the terminal device, thereby reducing its power consumption.

[0100] To make the technical solution of this application clearer and easier to understand, the communication method of multimodal services in the embodiments of this application will be described below with reference to the accompanying drawings. The embodiments of this application are applicable to data transmission processes in wireless communication scenarios. In this embodiment, multimodal service transmission between a terminal device and a network device is taken as an example, such as multimodal service transmission between a single terminal device and a network device. The above-mentioned multimodal service between a terminal device and a network device is only a feasible example. The embodiments of this application can be applied to data transmission between terminal devices, or data transmission between network devices, or data transmission between two network elements in a wireless communication network.

[0101] Please refer to Figure 3, which shows a schematic diagram of an interaction process between a network device and a terminal device provided in an embodiment of this application. The communication method provided in this embodiment mainly includes the following steps:

[0102] 301. The network device sends the DRX indication information of the discontinuously received 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 this embodiment, to reduce the listening time and power consumption of the terminal device, the network device can send DRX indication information to the terminal device, indicating whether to enable or disable DRX retransmission. This allows the terminal device to disable retransmission based on the DRX indication information sent by the network device, reducing listening time and thus power consumption. Enabling retransmission means the terminal device can retransmit in the current DRX cycle; disabling retransmission means the terminal device cannot retransmit in the current DRX cycle. Retransmission refers to the terminal device receiving or transmitting retransmission information according to the retransmission timer and round-trip timer. Even without retransmission scheduling, the terminal device will receive retransmission information according to the retransmission timer and round-trip timer. When retransmission is disabled, the terminal device either does not receive retransmission information or does not activate the retransmission timer and round-trip timer. In this case, the terminal device will not receive or transmit retransmissions.

[0105] Specifically, network devices and terminal devices 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. This allows the terminal device to receive the DRX indication information and enable or disable retransmission of the DRX based on the DRX indication information. When the terminal device is listening to the DRX based on the DRX indication information, it can reduce the listening time by disabling retransmission, thereby reducing the power consumption of the terminal device.

[0106] In one possible implementation of this application embodiment, step 301, where the network device sends DRX indication information for discontinuously received DRX to the terminal device, includes:

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

[0108] DRX includes the DRX indication information.

[0109] In this embodiment, the network device and the terminal device can communicate with each other. 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. The DRX configuration information can also be simply referred to as DRX. The network device sends the DRX to the terminal device, so that when the terminal device receives the DRX, it can extract the DRX indication information from the DRX. When the terminal device listens according to the DRX indication information and DRX configuration parameters, it can reduce the listening time by enabling retransmission, thereby reducing the power consumption of the terminal device.

[0110] In this embodiment, the DRX configured by the network device may include DRX configuration parameters that disable retransmission. These DRX configuration parameters can be pre-configured by the network device. For DRX configuration parameters or DRX periods that require disabling retransmission, the network device may not configure corresponding round-trip time timers and retransmission timers. This ensures that after the network device sends the DRX to the terminal device, the terminal device will not listen for retransmission, thereby reducing the terminal device's listening time and lowering its transmission power consumption.

[0111] In this embodiment, before the network device sends DRX indication information, the network device can configure DRX and DRX indication information according to the service type of the terminal device. The service type may include multimodal services. Since terminal devices typically use DRX to save power during data transmission, and different types of service data usually require different DRX configurations, and multimodal service data may include data from 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. Each set of DRX configuration parameters corresponds to a service data type or service period, and the period of each set of DRX configuration parameters may be different. That is, multiple sets of DRX configuration parameters may contain multiple periods, or each set of DRX configuration parameters may include multiple periods, or each set of DRX configuration parameters may have multiple listening opportunities within its period. In other words, the DRX configured by the network device may include multiple sets of DRX configuration parameters, or multiple DRX periods, or one or more listening opportunities within the included DRX periods. Multiple DRX configurations refer to each DRX configuration including one or more DRX configuration parameters. Therefore, after configuring DRX, network devices can first determine the DRX configuration parameters that enable retransmission, or the DRX period that enables retransmission, or the listening time that enables retransmission. Then, they can enable retransmission by configuring DRX indication information to indicate the DRX configuration parameters that enable retransmission, or the DRX period that enables retransmission, or the listening time that enables retransmission.

[0112] Specifically, when configuring DRX indication information, network devices can determine the DRX configuration parameters that enable retransmission, the DRX period that enables retransmission, or the listening time that enables retransmission based on the DRX period.

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

[0114] Since the DRX period directly determines the timing of the next data retransmission, a smaller DRX period is more likely to meet the PDB requirements, meaning it's more likely that the listener timer can be disabled without affecting data transmission content and quality. For example, the PDB of video service data can be between 10ms and 30ms, and each frame rate has corresponding latency requirements. For instance, at fps=60, the corresponding PDBs could be 10ms, 15ms, and 30ms. In this case, if the DRX period of the DRX configuration parameter for the video service data is 16.67ms, the interval between the time when the video service data is retransmitted in the next period and the time when the data is detected in the current period will be greater than 30ms. Therefore, under this latency requirement, it is not recommended to disable retransmission using the listener timer in the DRX configuration parameter for this video service data.

[0115] For example, when fps=120, the DRX period of the DRX configuration parameter 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 the retransmission scheduling and meet the PDB requirement in the next cycle. That is, the DRX configuration parameter corresponding to the video service data can enable retransmission by listening to the timer under this latency requirement.

[0116] For example, the period of the DRX configuration parameters corresponding to haptic service data is usually 2ms or 4ms, and the PDB requirement for haptic services is 10ms. In this case, if the period of the DRX configuration parameters corresponding to the haptic service data is 2ms, then the haptic service data can complete the retransmission scheduling and meet the PDB requirement in the next period. That is, the DRX configuration parameters corresponding to the haptic service data can enable retransmission by listening to the timer under this latency requirement.

[0117] In one possible implementation of this application embodiment, the DRX indication information is used to instruct at least one set of DRX configuration parameters in the DRX to enable retransmission. If the DRX includes one or more sets of DRX configuration parameters, the DRX indication information can be used to instruct one or more sets of DRX configuration parameters in the DRX to enable 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 be de-enabled for retransmission, the DRX indication information sent by the network device to the terminal device can be used to instruct DRX2 to enable retransmission, so that the terminal device can reduce the listening time and reduce the power consumption of the terminal device by de-enabled retransmission of DRX2 when listening.

[0118] In one possible implementation of this application embodiment, the DRX indication information is used to instruct at least one DRX cycle in the DRX to enable retransmission. If the DRX includes one or more DRX cycles, the DRX indication information can be used to instruct one or more DRX cycles in the DRX to enable retransmission. For example, referring to Figure 5, if the DRX includes two DRX cycles, cycle 1 and cycle 2, and it is determined through analysis that DRX2 is a DRX cycle that can be de-enabled for retransmission, the DRX indication information sent by the network device to the terminal device can be used to instruct cycle 2 to enable retransmission, so that the terminal device can reduce the listening time and reduce the power consumption of the terminal device by de-enabled retransmission of cycle 2 when listening.

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

[0120] In one possible implementation of this application embodiment, 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 retransmission to be disabled; the second indication is used to instruct the round-trip time timer to be turned off; the third indication is used to instruct the round-trip time timer to be set to infinity; and the fourth indication is used to instruct the retransmission timer to be set to zero. The DRX indication information sent by the network device to the terminal device can directly instruct retransmission to be disabled, allowing the terminal device to directly enable retransmission of the corresponding DRX configuration parameters, DRX period, or listening opportunity within the DRX period after receiving the DRX indication information. The DRX indication information sent by the network device to the terminal device can also instruct the round-trip time timer to be turned off, allowing the terminal device to disable retransmission by turning off the round-trip time timer after receiving the DRX indication information. The DRX indication information sent by the network device to the terminal device can also instruct the round-trip time timer to be set to infinity, allowing the terminal device to disable retransmission by setting the round-trip time timer to infinity after receiving the DRX indication information. The DRX indication information sent by the network device to the terminal device can also indicate that the retransmission timer is set to zero, so that the terminal device can disable retransmission by setting the retransmission timer to zero after receiving the DRX indication information.

[0121] In one possible implementation of this application embodiment, the round-trip time timer includes at least one of an uplink round-trip time timer and a downlink round-trip time timer; the retransmission timer includes at least one of an uplink retransmission time timer and a downlink retransmission time timer. Since the terminal device can transmit multimodal service data in two ways—uplink data transmission and downlink data reception—when the terminal device transmits uplink data, the DRX indication information can disable retransmission by indicating that the uplink round-trip timer is off, or by indicating that the uplink round-trip timer is set to infinity, or by indicating that the uplink retransmission timer is set to zero. This disables retransmission during uplink data transmission, reducing the listening time during uplink data transmission and thus reducing the power consumption of the terminal device when transmitting multimodal service data. When the terminal device receives downlink data, the DRX indication information can disable retransmission by indicating that the downlink round-trip timer is turned off, or by indicating that the downlink round-trip timer is set to infinity, or by indicating that the downlink retransmission timer is set to zero. This enables the terminal device to disable retransmission when receiving downlink data, reducing the listening time during downlink data transmission and thus reducing the power consumption of the terminal device.

[0122] In one possible implementation of this application, the DRX indication information includes at least one de-enable indicator. The de-enable indicator is used to indicate whether the DRX configuration parameter corresponding to the position of the de-enable indicator is enabled for retransmission. The position of the de-enable indicator corresponds to the configuration order of the DRX configuration parameters. The network device can design the DRX indication information based on the Medium Access Control Element (MAC CE). As shown in Figure 7, the indication information can consist of a tag identifier R and de-enable indicators A / D. Each de-enable indicator A / D corresponds to a set of DRX configuration parameters, and each de-enable indicator A / D is used to indicate whether the corresponding DRX configuration parameter is enabled for retransmission or retransmission is enabled. The correspondence between the de-enable indicator and the DRX configuration parameters can be determined based on the position of the de-enable indicator and the configuration order of the DRX configuration parameters. Specifically, the first disable indicator closest to the tag identifier R can be used to indicate that the first set of DRX configuration parameters can be enabled for retransmission, the second disable indicator can be used to indicate that the second set of DRX configuration parameters can be enabled for retransmission, and so on. This allows the DRX indication information to enable the corresponding DRX configuration parameters for retransmission through the disable indicators, thereby reducing the listening time and power consumption of the terminal device.

[0123] In one possible implementation of this application, the DRX indication information includes at least one disable indicator. The disable indicator is used to indicate whether retransmission is enabled in the DRX cycle corresponding to its position. The positions of the disable indicators correspond to the configuration order of the DRX cycles. As shown in Figure 7 above, each disable indicator A / D corresponds to one DRX cycle, and each disable indicator A / D is used to indicate whether retransmission is enabled or disabled in the corresponding DRX cycle. The correspondence between the disable indicators and the DRX cycles can be determined based on their positions and the configuration order of the DRX cycles. Specifically, the first disable indicator closest to the tag identifier R can be used to indicate whether retransmission is enabled in the first DRX cycle, the second disable indicator can be used to indicate whether retransmission is enabled in the second DRX cycle, and so on. This allows the DRX indication information to enable retransmission in the corresponding DRX cycle through the disable indicators, thereby reducing the terminal device's listening time and power consumption.

[0124] In one possible implementation of the first aspect of this application, the DRX indication information includes at least one de-enable indicator. The de-enable indicator is used to indicate whether retransmission is enabled at the listening time corresponding to the position of the de-enable indicator. The position of the de-enable indicator corresponds to the configuration order of the listening times. As shown in Figure 7 above, each de-enable indicator A / D corresponds to a listening time in a DRX cycle, and each de-enable indicator A / D is used to indicate whether retransmission is enabled or disabled at the corresponding listening time. The correspondence between the de-enable indicator and the listening time can be determined based on the position of the de-enable indicator and the configuration order of the DRX cycle. Specifically, the first de-enable indicator closest to the tag identifier R can be used to indicate whether retransmission is enabled at the first listening time in a DRX cycle, the second de-enable indicator can be used to indicate whether retransmission is enabled at the second listening time in a DRX cycle, and so on. This allows the DRX indication information to achieve de-enable retransmission in the corresponding DRX cycle through the de-enable indicators, enabling the terminal device to reduce listening time and power consumption.

[0125] In one possible implementation of the first aspect of this application, the DRX indication information includes at least one disable indicator and at least one DRX configuration parameter identifier. The disable indicator is used to indicate that the DRX configuration parameter corresponding to the corresponding DRX configuration parameter identifier is disabled for retransmission. As shown in Figure 8, the indication information can consist of a tag identifier R, a disable indicator A / D, and a DRX configuration parameter identifier DRX ID. Each DRX ID has a corresponding set of DRX configuration parameters, and each disable indicator A / D also has a corresponding DRX ID. That is, the disable indicator can be used to enable retransmission of the DRX configuration parameter corresponding to the corresponding DRX configuration parameter identifier. This allows the DRX indication information to enable and disable the retransmission of the corresponding DRX configuration parameter through the disable indicator and the DRX configuration parameter identifier, thereby reducing the listening time and power consumption of the terminal device.

[0126] In one possible implementation of the first aspect of this application, the DRX indication information includes at least one disable indicator and at least one DRX cycle identifier. The disable indicator is used to indicate that the DRX cycle corresponding to the corresponding DRX cycle identifier is disabled for retransmission. As shown in Figure 9, the indication information can be composed of a tag identifier R, a disable indicator A / D, and a DRX cycle identifier cycle ID. Each cycle ID corresponds to a DRX cycle, and each disable indicator A / D also corresponds to a cycle ID. That is, the disable indicator can be used to disable retransmission for the DRX cycle corresponding to the corresponding cycle identifier, so that the DRX indication information can achieve the disable retransmission of the corresponding DRX cycle through the disable indicator and the DRX cycle identifier, thereby reducing the listening time and power consumption of the terminal device.

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

[0128] In one possible implementation of this application embodiment, the network device can also construct indication information based on Radio Resource Control (RRC) signaling or Downlink Control Information (DCI) signaling. The construction method is as described in the above embodiments 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 listening time.

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

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

[0131] In this embodiment, the network device and the terminal device can communicate with each other. The network device sends DRX indication information to the terminal device to indicate whether to enable retransmission or to indicate whether to enable retransmission. The terminal device can then receive DRX configuration parameters so that it can enable retransmission according to the DRX indication information sent by the network device, thereby reducing listening time and reducing the power consumption of the terminal device.

[0132] In one possible implementation of this application embodiment, step 302, where the terminal device receives DRX indication information for discontinuous DRX reception from the network device, includes:

[0133] B1. Receive DRX from network devices.

[0134] DRX includes the DRX indication information.

[0135] In this embodiment, the network device and the terminal device can communicate with each other. The terminal device can receive the 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 when the terminal device receives the DRX, it can extract the DRX indication information from the DRX. When the terminal device listens to the DRX according to the DRX indication information and the DRX, it can reduce the listening time by enabling retransmission, thereby reducing the power consumption of the terminal device.

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

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

[0138] When a terminal device meets the data retransmission conditions specified in the DRX indication information (DRX indication information) regarding the DRX configuration parameters, DRX period, and listening timing that allow retransmission to be disabled, data retransmission can be avoided. This reduces the terminal device's listening time and power consumption without affecting data transmission content and quality. Specifically, disabling data retransmission can be achieved by disabling the round-trip time timer or disabling the retransmission timer. Disabling the round-trip time timer can include either not enabling the round-trip timer or setting the round-trip timer to infinity; disabling the retransmission timer can include either not enabling the retransmission timer or setting the retransmission timer to zero.

[0139] When the terminal device meets the data retransmission conditions indicated by the DRX indication information in the DRX configuration parameters, DRX period, and listening timing that enable retransmission, data retransmission can begin, thereby ensuring the content and quality of data transmission. Specifically, data retransmission can be performed by enabling a round-trip timer or enabling a retransmission timer. Enabling a round-trip timer can include enabling the round-trip timer; enabling a retransmission timer can include enabling a retransmission timer.

[0140] The above retransmission conditions include: listening to data scheduling at the active time corresponding to DRX, such as listening to data scheduling at the listening time corresponding to the duration timer or the listening time corresponding to the inactive timer, such as listening to PDCCH or Physical Downlink Shared Channel (PDSCH) or Physical Uplink Shared Channel (PUSCH).

[0141] In the embodiments of this application, the DRX indication information can indicate whether to enable uplink retransmission or enable downlink retransmission.

[0142] Specifically, as shown in Figure 4 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 parameter that can be deactivated for retransmission, such as DRX2, based on the DRX indication information. When the terminal device meets the retransmission activation condition corresponding to DRX2, such as detecting data during the activation time corresponding to DRX2, retransmission scheduling for DRX2 can be omitted. The terminal device can complete the data retransmission within the listening time of the next DRX2 cycle, thereby reducing the terminal device's listening time and power consumption without affecting the data transmission content and quality.

[0143] When the DRX indication information includes a first indication, which indicates whether DRX2 should disable retransmission, the specific indication can be:

[0144] When the first indication is used to enable retransmission, the round-trip timer can be started if data is detected at the activation time corresponding to DRX2.

[0145] When the first indication is used to indicate that retransmission is enabled, if data is detected for the activation time corresponding to DRX2, the round-trip timer will not be started; or the round-trip timer will be started and the activation duration of the round-trip timer will be set to infinity; or the round-trip timer will be started and the activation duration of the retransmission timer will be set to zero.

[0146] Specifically, since terminal devices can transmit multimodal service data in two ways, namely uplink data transmission and downlink data reception, when the data transmitted by the terminal device is uplink data, if the first indication is used to enable retransmission, for example, if the uplink data detected by the listening time corresponding to DRX2 will be retransmitted by the network and retransmission needs to be enabled, then the uplink round-trip time timer can be started when uplink data is detected by the activation time corresponding to DRX2.

[0147] When the data transmitted by the terminal device is uplink data, if the first indication is used to indicate that retransmission is disabled, for example, if the uplink data detected by the listening time corresponding to DRX2 will not be scheduled for retransmission by the network and retransmission needs to be disabled, then when uplink data is detected by the activation time corresponding to DRX2, the uplink round-trip timer is not enabled; or the uplink round-trip timer is enabled and the activation duration of the uplink round-trip timer is set to infinity; or the uplink round-trip timer is enabled and the activation duration of the uplink retransmission timer is set to zero.

[0148] When the terminal device receives downlink data, if the first indication is used to enable retransmission, for example, if the data detected by the listening time corresponding to DRX2 can be fed back via HARQ, then if downlink data is detected by the activation time corresponding to DRX2 and a negative acknowledgment (NACK) is returned, the downlink round-trip time timer can be started.

[0149] When the terminal device receives downlink data, if the first indication is used to indicate that retransmission is disabled, for example, if the data detected at the listening time corresponding to DRX2 cannot be used for HARQ feedback, then when downlink data is detected at the activation time corresponding to DRX2, HARQ feedback will not be performed and the downlink round-trip time timer will not be started; or the downlink round-trip time timer will be started 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 started and the activation duration of the downlink retransmission timer will be set to zero.

[0150] As shown in Figure 5 above, when DRX includes one or more DRX cycles, such as cycle 1 and cycle 2, the terminal device can determine the DRX cycle that can be deactivated for retransmission, such as cycle 2, based on the DRX indication information. When the terminal device meets the retransmission activation condition corresponding to cycle 2, such as detecting data during the activation time corresponding to cycle 2, it can cancel the retransmission scheduling for cycle 2 and complete the data retransmission within the listening time of the next cycle of cycle 2. This reduces the listening time of the terminal device and lowers its power consumption without affecting the data transmission content and quality.

[0151] When the DRX indication information includes a first indication, which indicates whether retransmission is disabled in cycle 2, it can specifically be:

[0152] When the first instruction is used to indicate that retransmission is enabled, the round-trip timer can be started if data is detected at the activation time corresponding to period 2.

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

[0154] Specifically, since terminal devices can transmit multimodal service data in two ways, namely uplink data transmission and downlink data reception, when the data transmitted by the terminal device is uplink data, if the first indication is used to enable retransmission, for example, if the uplink data detected during the listening time corresponding to cycle 2 will be scheduled for retransmission by the network, and retransmission needs to be enabled, then the uplink round-trip time timer can be started when uplink data is detected during the activation time corresponding to cycle 2.

[0155] When the data transmitted by the terminal device is uplink data, if the first indication is used to indicate that retransmission is disabled, for example, if the uplink data detected during the listening time corresponding to period 2 will not be scheduled for retransmission by the network and retransmission needs to be disabled, then when uplink data is detected during the activation time corresponding to period 2, the uplink round-trip timer is not enabled; or the uplink round-trip timer is enabled and the activation duration of the uplink round-trip timer is set to infinity; or the uplink round-trip timer is enabled and the activation duration of the uplink retransmission timer is set to zero.

[0156] When the terminal device receives downlink data, if the first indication is used to enable retransmission, for example, if the data detected during the listening time corresponding to cycle 2 can be fed back via HARQ, then if downlink data is detected during the activation time corresponding to cycle 2 and a NACK is returned, the downlink round-trip timer can be started.

[0157] When the terminal device receives downlink data, if the first indication is used to indicate whether to enable retransmission, for example, if the data detected at the listening time corresponding to period 2 cannot be used for HARQ feedback, then if downlink data is detected at the activation time corresponding to period 2, HARQ feedback will not be used and the downlink round-trip time timer will not be started; or the downlink round-trip time timer will be started 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 started and the activation duration of the downlink retransmission timer will be set to zero.

[0158] As shown in Figure 6 above, when a DRX cycle includes one or more listening opportunities, such as the three listening opportunities in cycle 1, the terminal device can determine from the DRX that the listening opportunities to disable retransmission can be enabled based on the DRX indication information, such as the second and third listening opportunities in cycle 1. When the terminal device meets the retransmission activation conditions corresponding to the second and third listening opportunities in cycle 1, such as when data is detected during the second and third listening opportunities in cycle 1, the retransmission scheduling for the second and third listening opportunities in cycle 1 can be cancelled, and the data retransmission can be completed within the first listening opportunity of the next cycle of cycle 1. This reduces the terminal device's listening time and power consumption without affecting the data transmission content and quality.

[0159] When the DRX indication information includes a first indication, which indicates whether to enable retransmission during the listening period, it can specifically be:

[0160] When the first instruction is used to enable retransmission, the round-trip timer can be started if data is detected at the activation time corresponding to the listening timing.

[0161] When the first instruction is used to enable retransmission, if data is detected at the activation time corresponding to the listening timing, the round-trip timer will not be started; or the round-trip timer will be started and its activation duration will be set to infinity; or the round-trip timer will be started and the retransmission timer's activation duration will be set to zero.

[0162] Specifically, since terminal devices can transmit multimodal service data in two ways, namely uplink data transmission and downlink data reception, when the data transmitted by the terminal device is uplink data, if the first indication is used to enable retransmission, for example, if the uplink data detected by the listening time corresponding to the listening time will be retransmitted by the network, and retransmission needs to be enabled, then the uplink round-trip time timer can be started when uplink data is detected at the activation time corresponding to the listening time.

[0163] When the data transmitted by the terminal device is uplink data, if the first indication is used to indicate that retransmission is disabled, for example, if the uplink data detected by the listening time corresponding to the listening time will not be scheduled for retransmission by the network and retransmission needs to be disabled, then if uplink data is detected at the activation time corresponding to the listening time, the uplink round-trip time timer will not be started; or the uplink round-trip time timer will be started and the activation duration of the uplink round-trip time timer will be set to infinity; or the uplink round-trip time timer will be started and the activation duration of the uplink retransmission timer will be set to zero.

[0164] When the terminal device receives downlink data, if the first indication is used to enable retransmission, for example, if the data listened to at the activation time corresponding to the listening time can be fed back via HARQ, then if downlink data is listened to at the activation time corresponding to the listening time and a NACK is returned, the downlink round-trip time timer can be started.

[0165] When the terminal device receives downlink data, if the first indication is used to indicate whether to enable retransmission, for example, if the data detected at the activation time corresponding to the listening time cannot be HARQ feedback, then when downlink data is detected at the activation time corresponding to the listening time, HARQ feedback will not be performed and the downlink round-trip time timer will not be started; or the downlink round-trip time timer will be started 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 started and the activation duration of the downlink retransmission timer will be set to zero.

[0166] In one possible implementation of this application embodiment, when the DRX indication information includes a second indication, the monitoring based on the DRX and the DRX indication information includes: determining the target monitoring timing to be deactivated from the DRX based on the DRX indication information; and disabling the round-trip timer corresponding to the target monitoring timing. During the monitoring process based on the DRX and the DRX indication information, the terminal device can first determine the target monitoring timing to be deactivated from the DRX based on the DRX indication information. The target monitoring timing may include monitoring timings corresponding to at least one set of DRX configuration parameters in the DRX, or monitoring timings corresponding to at least one DRX cycle in the DRX, or at least one monitoring timing in one cycle of the DRX. When the terminal device meets the retransmission activation condition corresponding to the target monitoring timing, it can disable retransmission by disabling the round-trip timer, preventing the retransmission timer from being triggered, thereby reducing the monitoring time of the terminal device and reducing the power consumption of the terminal device.

[0167] Specifically, since terminal devices can transmit multimodal service data in two ways—uplink data transmission and downlink data reception—when transmitting uplink data, the terminal device can disable uplink retransmission by disabling the uplink round-trip timer when the retransmission activation condition corresponding to the target listening time is met. This prevents the uplink retransmission timer from being triggered. Similarly, when receiving downlink data, the terminal device can disable downlink retransmission by disabling the downlink round-trip timer when it detects downlink data during the listening time corresponding to the DRX mechanism that allows retransmission to be disabled.

[0168] In one possible implementation of this application embodiment, when the DRX indication information includes a third indication, the monitoring based on the DRX and the DRX indication information includes: determining the target monitoring opportunity to disable retransmission from the DRX based on the DRX indication information; and setting the value of the round-trip timer corresponding to the target monitoring opportunity to infinity. During the monitoring process based on the DRX and the DRX indication information, the terminal device can first determine the target monitoring opportunity to disable retransmission from the DRX based on the DRX indication information. The target monitoring opportunity may include monitoring opportunities corresponding to at least one set of DRX configuration parameters in the DRX, or monitoring opportunities corresponding to at least one DRX cycle in the DRX, or at least one monitoring opportunity in one cycle of the DRX. When the terminal device meets the retransmission activation condition corresponding to the target monitoring opportunity, it can disable retransmission by enabling the round-trip timer and setting its activation duration to infinity. This ensures that the terminal device always keeps the round-trip timer active, preventing the retransmission timer from being triggered, reducing the monitoring time of the retransmission timer during data transmission, thereby reducing the terminal device's monitoring time and power consumption.

[0169] Specifically, since terminal devices can transmit multimodal service data in two ways—uplink data transmission and downlink data reception—when transmitting uplink data, the terminal device can disable retransmission by enabling the uplink round-trip timer and setting its activation duration to infinity when the retransmission activation condition corresponding to the target listening time is met. This ensures the uplink round-trip timer is always active and the uplink retransmission timer cannot be triggered. Similarly, when receiving downlink data, the terminal device can disable retransmission by enabling the downlink round-trip timer and setting its activation duration to infinity when the retransmission activation condition corresponding to the target listening time is met. This ensures the downlink round-trip timer is always active and the downlink retransmission timer cannot be triggered.

[0170] In one possible implementation of this application embodiment, when the DRX indication information includes a fourth indication, the monitoring based on the DRX and the DRX indication information includes: determining the target monitoring timing to be enabled for retransmission from the DRX based on the DRX indication information; and setting the value of the retransmission timer corresponding to the target monitoring timing to zero. During the monitoring process based on the DRX and the DRX indication information, the terminal device can first determine the target monitoring timing to be enabled for retransmission from the DRX based on the DRX indication information. The target monitoring timing may include monitoring timings corresponding to at least one set of DRX configuration parameters in the DRX, or monitoring timings corresponding to at least one DRX cycle in the DRX, or at least one monitoring timing in one cycle of the DRX. When the terminal device meets the retransmission activation condition corresponding to the target listening time, retransmission can be disabled by enabling the round-trip timer and setting the activation duration of the retransmission timer to zero. This causes the terminal device to start the round-trip timer. However, when the listening time of the round-trip timer ends, the retransmission timer cannot be triggered because the activation duration of the retransmission timer is zero. This 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 terminal devices can transmit multimodal service data in two ways—uplink data transmission and downlink data reception—when transmitting uplink data, the terminal device can disable retransmission by enabling the uplink round-trip timer and setting its activation duration to zero when the retransmission activation condition corresponding to the target listening time is met. This prevents the uplink retransmission timer from being triggered when its listening time ends. Similarly, when receiving downlink data, the terminal device can disable retransmission by enabling the downlink round-trip timer and setting its activation duration to zero when the retransmission activation condition corresponding to the target listening time is met.

[0172] As illustrated by the examples above, compared to the prior art where directly configuring and sending multiple sets of DRX configuration parameters to the terminal device may result in excessively long listening times for the terminal device, in order to reduce the listening time and power consumption of the terminal device, the network device can send DRX indication information to the terminal device to instruct the DRX to enable retransmission or to disable retransmission. This allows the terminal device to disable retransmission of the DRX according to the DRX indication information sent by the network device, thereby reducing the listening time of the terminal device and thus reducing the power consumption of the terminal device.

[0173] To make the technical solution of this application clearer and easier to understand, the communication method of this application will be described below in conjunction with specific data transmission scenarios of terminal devices and network devices.

[0174] First, referring to Figure 10a, which shows a schematic diagram of data transmission between a terminal device and a network device, the method includes the following steps:

[0175] S01, gNB sends the DRX with retransmission disabled to the UE.

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

[0177] In this embodiment, the DRX sent by the gNB to the UE may include a DRX with retransmission disabled. The DRX configuration parameters with retransmission disabled can be pre-configured DRX configuration parameters by the gNB. For DRX configuration parameters or DRX periods that require retransmission disabled, the gNB may directly omit the corresponding round-trip time timer and retransmission timer in the DRX configuration parameters. Alternatively, the DRX may include DRX indication information, so that after the gNB sends the DRX to the UE, if the UE detects data within the DRX's listening time, it may not perform retransmission scheduling, thereby reducing the UE's listening time and lowering the UE's transmission power consumption.

[0178] Secondly, referring to Figure 10b, another schematic diagram of data transmission between a terminal device and a network device, the method includes the following steps:

[0179] S11, gNB will send the DRX with retransmission disabled to UE.

[0180] Among them, the DRX configuration for disabling retransmission includes the DRX configuration parameters for disabling retransmission.

[0181] In this embodiment of the application, the DRX sent by the gNB to the UE may include a DRX with retransmission disabled. The DRX configuration parameters with retransmission disabled can be DRX configuration parameters pre-configured by the gNB. For DRX configuration parameters or DRX periods that require retransmission disabled, the gNB may directly omit the corresponding round-trip time timer and retransmission timer in the DRX configuration parameters, or the DRX may include DRX indication information.

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

[0183] The DRX indication information is used to indicate whether to enable or disable retransmission.

[0184] In this embodiment of the application, after the gNB sends the DRX to the UE to disable retransmission, it can continue to send DRX indication information to the UE. This allows the UE to disable retransmission or enable retransmission during data transmission based on the listening time 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 Figure 10c, another schematic diagram of data transmission between a terminal device and a network device is shown. The method includes the following steps:

[0186] S21 and gNB send DRX to UE.

[0187] In this embodiment of the application, when configuring a new DRX, the gNB can directly use the common parameters of the DRX configuration parameters in other DRXs to configure it. That is, when configuring a new DRX, the configured DRX can only include the DRX configuration parameters that need to enable retransmission.

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

[0189] The DRX indication information is used to indicate whether to enable or disable retransmission.

[0190] In this embodiment of the application, after the gNB sends the configured DRX to the UE, it can continue to send DRX indication information to the UE to indicate that the DRX configuration parameters that can be de-enabled for retransmission in the configured DRX should be enabled for retransmission. This allows the UE to enable retransmission of the configuration parameters that can be de-enabled for retransmission indicated by the DRX indication information during data transmission, thereby reducing the UE's listening 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 do not mean that this application only provides the above methods. In actual application, the steps of the above embodiments can be split or combined, and this application does not limit this.

[0194] In the above implementation scheme, 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 to indicate whether to enable or disable DRX retransmission. This allows the terminal device to disable retransmission according to the DRX indication information sent by the network device, thereby reducing the listening time and reducing the power consumption of the terminal device.

[0208] As illustrated by the examples above, compared to the prior art where directly configuring and sending multiple sets of DRX configuration parameters to the terminal device may result in excessively long listening times for the terminal device, in order to reduce the listening time and power consumption of the terminal device, the network device can send DRX indication information to the terminal device to instruct the DRX to enable retransmission or to disable retransmission. This allows the terminal device to disable retransmission of the DRX according to the DRX indication information sent by the network device, thereby reducing the listening time of the terminal device and thus reducing the power consumption of the terminal device.

[0236] Figure 13 illustrates an example of the composition of an electronic device provided in an embodiment of this application. This electronic device may be a first device, including but not limited to a base station and a core network unit. Figure 13 shows a simplified schematic diagram of a base station structure. The base station includes a 1310 section, a 1320 section, and a 1330 section. The 1310 section is mainly used for baseband processing and controlling the base station; the 1310 section is typically the control center of the base station, often referred to as a processor, used to control the base station to execute the processing operations on the first device side in the above method embodiments.
