Technical Field

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

[0003] 5G communication systems support larger bandwidths and more antennas. Therefore, reducing the power consumption of both network devices and terminals in 5G communication systems is crucial. Currently, terminals can use the connected mode discontinuous reception (C-DRX) mechanism to receive data, thereby reducing terminal power consumption. Network devices can use the cell discontinuous reception (DRX) and cell discontinuous transmission (DTX) mechanisms to receive and send data, thereby reducing power consumption.

[0004] Summary of the Invention

[0005] The present application provides a transmission indication method, apparatus, communication equipment, and storage medium, which can reduce the power consumption of a network device when transmitting data with a non-connected terminal.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] In a first aspect, a transmission indication method is provided, the method comprising: sending first indication information to a first terminal, the first indication information being used to indicate whether the discontinuous reception DRX and / or discontinuous transmission DTX functions of a first cell in which the first terminal is located are enabled or disabled, the first terminal being in a non-connected state, the non-connected state including an idle state and an inactive state.

[0008] In the present application, a network device may send first indication information to a terminal in a non-connected state to indicate whether the DRX and / or DTX functions of the first cell in which the terminal is located are enabled or disabled. In this way, the terminal in the non-connected state may transmit other indication information or data to the network device based on the first indication information. Therefore, the present application implements indicating cell DRX and / or cell DTX to a terminal in a non-connected state, thereby reducing the power consumption of the network device when transmitting data with the terminal in the non-connected state.

[0009] Optionally, the implementation process of sending the first indication information to the first terminal may include: sending PEI downlink control information (DCI) to the first terminal within the paging early indication (PEI) opportunity corresponding to the first terminal, the PEIDCI including a transmission indication field, the transmission indication field being used to carry the first indication information, and the first time unit including the PEI opportunity.

[0010] In this application, the network device can reuse PEIDCI to carry the first indication information, thus saving DCI overhead. In addition, the terminal can obtain the first indication information by monitoring the PEI opportunity without additionally monitoring other opportunities, thus saving terminal power consumption.

[0011] Optionally, before sending the first indication information to the first terminal, the method further includes: sending configuration information to the first terminal, where the configuration information is used to indicate the starting position and length of the transmission indication field in the PEIDCI.

[0012] In this application, the network device can pre-send configuration information to the first terminal, and use the configuration information to indicate the position of the first indication information in the PEIDCI. In this way, the first terminal can obtain the first indication information from the PEIDCI more accurately and quickly based on the configuration information.

[0013] Optionally, the implementation process of sending the first indication information to the first terminal may include: sending the first indication information to the first terminal within a first time unit, the time difference between the first time unit and the second time unit is less than a preset time threshold, and the second time unit is a time unit for sending a synchronization signal block (SSB).

[0014] In the present application, the first time unit for the network device to send the first indication information can be as close as possible to the second time unit for sending the SSB, that is, the time difference between the first time unit and the second time unit can be less than the preset time threshold. In this way, the sending time of the network device can be concentrated as much as possible, that is, the network device can complete the sending in the shortest possible time, thereby turning off the sending for the longest possible time period to achieve better energy saving effects.

[0015] Optionally, the first indication information is also used to indicate a first receiving mode, and the first terminal is pre-configured with at least two C-DRX modes, and the at least two C-DRX modes include the first receiving mode.

[0016] In the present application, the network device can also indicate to the first terminal through the first indication information the C-DRX mode to be adopted when the first terminal switches to the connected state. In this way, once the first terminal switches to the connected state, it can immediately enable the C-DRX mode indicated by the first indication information to receive data without waiting and listening for further instructions from the network device, thereby saving terminal power consumption.

[0017] In a second aspect, a transmission indication method is provided, characterized in that the method includes: receiving first indication information, the first indication information being used to indicate whether the DRX and / or DTX functions of the first cell in which the first terminal is located are enabled or disabled, the first terminal being in a non-connected state, the non-connected state including an idle state and an inactive state; and transmitting other indication information or data based on the first indication information.

[0018] In the present application, a terminal in a non-connected state can receive a first indication message sent by a network device, and transmit other indication information or data to the network device based on the enabled status of the DRX and / or DTX functions of the first cell in which the terminal is located as indicated by the first indication message. It can be seen that the present application realizes indicating cell DRX and / or cell DTX to a terminal in a non-connected state, thereby reducing the power consumption of the network device when transmitting data with a terminal in a non-connected state.

[0019] Optionally, the implementation process of receiving the first indication information may include: receiving PEI downlink control information DCI within the paging advance indication PEI opportunity corresponding to the first terminal, the PEIDCI including a transmission indication field, and the transmission indication field is used to carry the first indication information.

[0020] In this application, the network device can reuse PEIDCI to carry the first indication information, thus saving DCI overhead. In addition, the terminal can obtain the first indication information by monitoring the PEI opportunity without additionally monitoring other opportunities, thus saving terminal power consumption.

[0021] Optionally, the method also includes: receiving configuration information, the configuration information being used to indicate the starting position and length of the transmission indication field in the PEIDCI; after receiving the PEI downlink control information DCI within the paging advance indication PEI opportunity corresponding to the first terminal, it also includes: obtaining the first indication information from the PEIDCI based on the starting position and length of the transmission indication field.

[0022] In this application, the network device can pre-send configuration information to the first terminal, and use the configuration information to indicate the position of the first indication information in the PEIDCI. In this way, the first terminal can obtain the first indication information from the PEIDCI more accurately and quickly based on the configuration information.

[0023] Optionally, the implementation process of receiving the first indication information may include: receiving the first indication information within a first time unit, the time difference between the first time unit and the second time unit is less than a preset time threshold, and the second time unit is a time unit for receiving the synchronization signal block SSB.

[0024] In the present application, the first time unit for the network device to send the first indication information can be as close as possible to the second time unit for sending the SSB, that is, the time difference between the first time unit and the second time unit can be less than a preset time threshold. In this way, the network device's transmission time can be concentrated as much as possible, that is, the network device can complete the transmission in the shortest possible time, thereby shutting down the transmission for the longest possible period of time to achieve better energy saving effects. Correspondingly, the terminal can also concentrate on monitoring the signal in the shortest possible time, thereby not monitoring for the longest possible period of time, thereby achieving better energy saving effects.

[0025] Optionally, the implementation process of transmitting other indication information or data based on the first indication information may include: if the first indication information indicates that the DRX function of the first cell is enabled, uplink data is sent during the activation time period of the DRX cycle of the first cell, and uplink data is not sent during the non-activation time period.

[0026] When the DRX function of the first cell is enabled, if the first terminal has data to be sent, the first terminal will concentrate on sending uplink data during the activation time period of the DRX cycle of the first cell, and will not send data during the inactivation time period of the DRX cycle of the first cell. In this way, while the network equipment saves energy, it can better ensure that the service of the first terminal is not affected.

[0027] Optionally, the implementation process of transmitting other indication information or data based on the first indication information may include: if the first indication information indicates that the DTX function of the first cell is enabled, then other indication information or downlink data is received during the activation time period of the DTX cycle of the first cell, and other indication information or downlink data is not received during the inactivation time period.

[0028] When the DTX function of the first cell is enabled, the first terminal can centrally monitor and receive downlink signals during the activation time period of the DTX cycle of the first cell, and not monitor downlink signals during the inactivation time period of the DTX cycle of the first cell. In this way, while the network equipment saves energy, it can better ensure that the service of the first terminal is not affected.

[0029] Optionally, the first indication information is also used to indicate a first receiving mode, and the first terminal is pre-configured with at least two connected discontinuous reception C-DRX modes, and the at least two C-DRX modes include the first receiving mode.

[0030] Optionally, the implementation process of transmitting other indication information or data based on the first indication information may include: after the first terminal switches from the non-connected state to the connected state, receiving downlink data or other indication information based on the first receiving mode.

[0031] In the present application, the first indication information can also indicate to the first terminal the C-DRX mode to be adopted when the first terminal switches to the connected state. In this way, once the first terminal switches to the connected state, it can immediately enable the C-DRX mode indicated by the first indication information to receive data without waiting and listening for further instructions from the network device, thereby saving terminal power consumption.

[0032] In a third aspect, a transmission indication device is provided, the transmission indication device comprising at least one module, and the at least one module is used to execute the transmission indication method described in the first aspect or the second aspect.

[0033] In a fourth aspect, a communication device is provided, comprising a processor, wherein the processor is configured to execute at least one program instruction or code stored in a memory to implement the transmission indication method described in the first or second aspect above.

[0034] In a fifth aspect, a computer-readable storage medium is provided, wherein instructions are stored in the computer-readable storage medium. When the instructions are executed on a communication device, the communication device executes the transmission indication method described in the first or second aspect above.

[0035] In a sixth aspect, a computer program product comprising instructions is provided. When the computer program product is run on a communication device, the communication device executes the transmission indication method described in the first or second aspect above.

[0036] The technical effects obtained by the above-mentioned third, fourth, fifth and sixth aspects are similar to the technical effects obtained by the corresponding technical means in the first and second aspects, and will not be repeated here.

[0037] In an embodiment of the present application, a network device may send first indication information to a terminal in a non-connected state to indicate whether to enable or disable the DRX and / or DTX functions of a first cell in which the terminal is located. In this way, the terminal in the non-connected state may transmit other indication information or data to the network device based on the first indication information. Therefore, the embodiment of the present application enables indicating cell DRX and / or cell DTX to a terminal in a non-connected state, thereby reducing power consumption of the network device when transmitting data with the terminal in the non-connected state.

[0047] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0048] Before explaining the embodiments of the present application in detail, the application scenarios involved in the embodiments of the present application are first introduced.

[0049] In communication systems, especially 5G communication systems, energy saving of terminals and network equipment is of great significance. Currently, for terminals, the C-DRX mechanism can be used to receive data, thereby reducing the power consumption of the terminal. For network equipment, cell DRX can be used to receive data and / or the cell DTX mechanism can be used to send data, thereby reducing the power consumption of the network equipment. Currently, before a network equipment adopts the cell DRX and / or cell DTX mechanism to transmit data, it can first indicate the terminals that are located within the coverage of the cell provided by the network equipment and are in a connected state through dedicated downlink control information (DCI), so that the terminals in the connected state can transmit data with the network equipment according to the cell DRX mechanism and / or cell DTX mechanism.

[0050] However, there are not only terminals in a connected state in the network, but also terminals in a non-connected state, for example, terminals in an idle state or an inactive state. For terminals in a non-connected state, the network device can indicate the relevant information of the cell DRX and / or cell DTX to these terminals in the non-connected state through the transmission indication method provided in the embodiment of the present application, so that the terminals in the non-connected state can send and receive data according to the relevant information of the cell DRX and / or DTX indicated by the network device, thereby reducing the power consumption of the network device.

[0051] Next, some of the nouns involved in the embodiments of this application are introduced.

[0052] (1) C-DRX

[0053] C-DRX is a mechanism for terminals to receive data while connected, designed to save energy. Based on the C-DRX mechanism, a terminal's C-DRX cycle consists of active and inactive periods. During the active period, the terminal monitors indications and downlink data sent by network devices, such as the PDDCH and PDSCH. During the inactive period, the terminal is dormant and does not monitor unicast scheduling information or scheduled downlink data sent via the PDCCH, thereby saving power.

[0054] (2) Cell DTX

[0055] Cell DTX is a mechanism for network devices to send data for energy saving. Based on the cell DTX mechanism, the DTX period of a certain cell provided by the network device includes an activation period and an inactivation period. During the activation period of the DTX period of the cell, the network device sends specific indication information (such as unicast scheduling information) or downlink data to the terminals within the signal coverage of the cell on the cell. During the inactivation period of the DTX period of the cell, the network device does not send specific indication information (such as unicast scheduling information) or downlink data on the cell. That is, through the cell DTX mechanism, the network device can concentrate the data to be sent on the cell in the activation period for transmission, while during the inactivation period, the network devices associated with the cell, such as base stations, enter a dormant state and do not send indication information or downlink data-related signals, thereby achieving the purpose of saving power consumption.

[0056] (3) Cell DRX

[0057] Cell DRX is a data reception mechanism for network devices, designed to save energy. Based on the cell DRX mechanism, the DRX cycle for a cell provided by the network device consists of an active period and an inactive period. During the active period of the cell's DRX cycle, the network device receives uplink signals from terminals within the cell's signal coverage. During the inactive period of the cell's DRX cycle, the network device does not receive uplink signals. In other words, the cell DRX mechanism allows the network device to focus on receiving uplink signals during the active period of the cell's DRX cycle, while the cell enters a dormant state and does not receive uplink signals during the inactive period, thereby saving power.

[0058] Next, the structure of the communication system involved in the transmission indication method provided in the embodiment of the present application is introduced.

[0059] Figure 1 is a schematic diagram of the structure of a communication system provided by an embodiment of the present application. As shown in Figure 1, the communication system includes a network device 101 and a terminal 102. A wireless communication connection is established between the network device 101 and the terminal 102.

[0060] In an embodiment of the present application, terminal 102 may be a terminal in a non-connected state, for example, a terminal in an idle state or an inactive state. Network device 101 may send first indication information to terminal 102, where the first indication information is used to indicate whether the DRX and / or DTX functions of the cell in which terminal 102 is located are enabled or disabled. After receiving the first indication information, terminal 102 may receive other indication information or data based on the first indication information. Thus, it can be seen that the embodiment of the present application implements the indication of cell DRX and / or cell DTX to a terminal in a non-connected state, thereby reducing the power consumption of the network device when transmitting data with a terminal in a non-connected state.

[0061] It should be noted that the above-mentioned communication system can be a 5G NR communication system, a long term evolution (LTE) network, an enhanced long term evolution (eLTE) network, a universal mobile telecommunications system (UMTS), a code division multiple access (CDMA) system, a wireless local area network (WLAN), etc., and can also be a sixth generation (6G) communication system or other future-oriented communication system. In addition, the communication system provided in the embodiment of the present application can be used for a terrestrial network (TN) and / or a non-terrestrial network (NTN) without limitation.

[0062] The network device 101 may refer to a base station (BS) in a wireless communication system. The base station may have various forms, such as a macro base station, a micro base station, a relay station, and an access point. For example, when the communication system is a 5G NR communication system, the network device 101 may be a base station in 5G, wherein the base station in 5G may also be referred to as a transmission reception point (TRP) or a next-generation base station (generation node B, gNB). When the communication system is an LTE communication system, the network device 101 may be an evolved node B (eNB). In an embodiment of the present application, the device for implementing the function of the network device may be a network device. Alternatively, a device capable of supporting the network device to implement the function may be installed in the network device, for example, the device is a chip system.

[0063] The terminal 102 is located within the signal coverage of the cell provided by the network device 101. The terminal 102 can also be called a terminal device, which is a device with wireless transceiver functions. The terminal 102 can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted, or can be deployed on the water surface (such as a ship, etc.), or can be deployed in the air (such as an airplane, a balloon, and a satellite, etc.). The terminal 102 can be a user equipment (UE), wherein the UE includes a handheld device, a vehicle-mounted device, a wearable device, or a computing device with wireless communication functions. Exemplarily, the UE can be a mobile phone, a tablet computer, or a computer with wireless transceiver functions. The terminal 102 can also be a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. In the embodiment of the present application, the device for realizing the functions of the terminal can be called a terminal. Alternatively, a device capable of supporting the terminal to implement the function may be installed in the terminal, for example, the device may be a chip system, wherein the chip system may be composed of a chip, or may include a chip and other discrete devices.

[0064] FIG2 is a schematic diagram of the structure of a terminal provided in an embodiment of the present application. The terminal involved in the embodiment of the present application can be implemented by the terminal 200 shown in FIG2. As shown in FIG2, the terminal 200 includes components such as a radio frequency (RF) circuit 210, a memory 220, other input devices 230, a display screen 240, a sensor 250, an audio circuit 260, an I / O subsystem 270, a processor 280, and a power supply 290. Those skilled in the art will appreciate that the terminal structure shown in FIG2 does not constitute a limitation on the terminal, and may include more or fewer components than shown, or combine certain components, or split certain components, or arrange different components. Those skilled in the art will appreciate that the display screen 240 belongs to a user interface (UI), and the terminal 200 may include more or fewer user interfaces than shown.

[0065] The following is a detailed introduction to the various components of the terminal 200 in conjunction with FIG2 :

[0066] RF circuit 210 can be used to send and receive information or receive and send signals during a call. For example, after receiving downlink information from a base station, RF circuit 210 can transmit this downlink information to processor 280 for processing. In addition, RF circuit 210 can also send uplink data to the base station. Typically, RF circuit 210 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier (LNA), a duplexer, and the like.

[0067] The memory 220 can be used to store software programs and modules, and the processor 280 executes various functional applications and data processing of the terminal 200 by running the software programs and modules stored in the memory 220. For example, the memory 220 may store a program for implementing the technical solution of the present application, and the processor 280 may implement the transmission indication method provided in the embodiment of the present application by executing the program. The memory 220 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area may store data created according to the use of the terminal 200 (such as audio data, a phone book, etc.), etc. In addition, the memory 220 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage device.

[0068] Other input devices 230 can be used to receive input numeric or character information and generate key signal input related to user settings and function control of terminal 200. Exemplarily, other input devices 230 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, on / off keys, etc.), a trackball, a mouse, a joystick, an optical mouse (an optical mouse is a touch-sensitive surface that does not display visual output, or is an extension of a touch-sensitive surface formed by a touch screen), etc. Other input devices 230 are connected to other input device controller 271 of I / O subsystem 270 and exchange signals with processor 280 under the control of other input device controller 271.

[0069] The display screen 240 can be used to display information input by the user or information provided to the user and various menus of the terminal 200, and can also receive user input. Exemplarily, the display screen 240 may include a display panel 241 and a touch panel 242. Among them, the display panel 241 can be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), etc. The touch panel 242, also known as a touch screen, a touch-sensitive screen, etc., can collect user contact or non-contact operations on or near it, for example, the user uses any suitable object or accessory such as a finger, a stylus, etc. to operate on or near the touch panel 242 and somatosensory operations, and drive the corresponding connection device according to a pre-set program. Among them, the above-mentioned operations include single-point control operations, multi-point control operations, and other operation types. Optionally, the touch panel 242 may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch direction and posture, and detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, and converts the touch information into information that can be processed by the processor 280, and then sends it to the processor 280. In addition, the touch controller can also receive commands sent by the processor 280 and execute them. In addition, the touch panel 242 can be implemented using various types such as resistive, capacitive, infrared and surface acoustic wave, and any technology developed in the future can also be used to implement the touch panel 242. Furthermore, the touch panel 242 can cover the display panel 241, and the user can operate on or near the touch panel 242 covered on the display panel 241 according to the content displayed on the display panel 241, wherein the content displayed on the display panel 241 includes but is not limited to a soft keyboard, a virtual mouse, virtual buttons, icons, etc. After the touch panel 242 detects an operation on or near it, it transmits the information to the processor 280 via the I / O subsystem 270 to determine the user input. The processor 280 then provides corresponding visual output on the display panel 241 via the I / O subsystem 270 based on the user input. Although in FIG2 , the touch panel 242 and the display panel 241 are two independent components to implement the input and output functions of the terminal 200, in some embodiments, the touch panel 242 and the display panel 241 can be integrated to implement the input and output functions of the terminal 200.

[0070] The terminal 200 may also include at least one sensor 250, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor, wherein the ambient light sensor may adjust the brightness of the display panel 241 according to the brightness of the ambient light, and the proximity sensor may turn off the display panel 241 and / or the backlight when the terminal 200 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the terminal posture, such as horizontal and vertical screen switching, related games, magnetometer posture calibration, etc. It can also be used for vibration recognition related functions, such as pedometer, tapping, etc.; as for other sensors that the terminal 200 can also be configured with, such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be described here.

[0071] Audio circuit 260, speaker 261, and microphone 262 provide an audio interface between the user and terminal 200. Audio circuit 260 can convert received audio data into signals and transmit them to speaker 261, which converts them into sound signals for output. Microphone 262, on the other hand, converts collected sound signals and sends them to audio circuit 260, which converts the received signals into audio data. The audio circuit then outputs the audio data to RF circuit 210 for transmission, for example, to another terminal, or to memory 220 for further processing.

[0072] The I / O subsystem 270 is used to control external input and output devices and may include an additional input device controller 271, a sensor controller 272, and a display controller 273. Optionally, one or more additional input device controllers 271 receive signals from and / or send signals to additional input devices 230. Additional input devices 230 may include physical buttons such as push buttons and rocker buttons, dials, slide switches, joysticks, click wheels, and optical mice. It is worth noting that the additional input device controller 271 can be connected to any one or more of the aforementioned input devices. The display controller 273 in the I / O subsystem 270 receives signals from and / or sends signals to the display screen 240. After the display screen 240 detects user input, the display controller 273 converts the detected user input into interaction with user interface objects displayed on the display screen 240, thereby achieving human-computer interaction. The sensor controller 272 can receive signals from and / or send signals to one or more sensors 250.

[0073] Processor 280 is the control center of terminal 200. It connects all components of the terminal using various interfaces and circuits. By running or executing software programs and / or modules stored in memory 220 and accessing data stored in memory 220, it executes various functions of terminal 200 and processes data, thereby providing overall terminal monitoring. Optionally, processor 280 may include one or more processing units. Preferably, processor 280 integrates an application processor and a modem processor. The application processor primarily handles the operating system, user interface, and application programs, while the modem processor primarily handles wireless communications. It is understood that the modem processor may not be integrated into processor 280.

[0074] The terminal 200 may further include a power supply 290, such as a battery, for supplying power to various components. Optionally, the power supply may be logically connected to the processor 280 via a power management system, thereby managing charging, discharging, and power consumption through the power management system.

[0075] Although not shown, the terminal 200 may also include components such as a camera and a Bluetooth module, which will not be described in detail in this embodiment of the present application.

The network device involved in the embodiment of the present application can be implemented by the network device shown in Figure 3. As shown in Figure 3, the network device may include at least one processor 301, a communication bus 302, a memory 303 and at least one communication interface 304. It should be noted that the device structure shown in Figure 3 does not constitute a limitation on the network device. The network device may include more or fewer components than shown in the figure, or combine certain components, or arrange components differently, which is not limited in the embodiment of the present application. The following is a detailed introduction to the various components of the network device in conjunction with Figure 3:

[0077] The processor 301 is the control center of the network device, which can be a processor or a general term for multiple processing elements. For example, the processor 301 can be a general-purpose central processing unit (CPU), or an application-specific integrated circuit (ASIC), or one or more integrated circuits for controlling the execution of the program of the present application, such as one or more microprocessors (digital signal processors, DSPs), or one or more field programmable gate arrays (FPGAs). The processor 301 can perform various functions of the network device by running or executing software programs stored in the memory 303 and calling data stored in the memory 303. For example, the actions of the network device in each embodiment described below can be executed by the processor of the network device calling data in the memory.

The processor herein may refer to one or more devices, circuits, and / or processing cores for processing data (e.g., computer program instructions).

[0080] Communication bus 302 may include a path for transmitting information between the aforementioned components. Communication bus 302 may be an Industry Standard Architecture (ISA) bus, a Peripheral Component Interconnect (PCI) bus, or an Extended Industry Standard Architecture (EISA) bus. Such buses may be classified as address buses, data buses, or control buses. For ease of illustration, FIG3 shows a single thick line, but this does not imply a single bus or type of bus.

For example, the output device 306 can be a liquid crystal display (LCD), a light emitting diode (LED) display device, a cathode ray tube (CRT) display device, or a projector. The input device 307 communicates with the processor 301 and can receive input in a variety of ways. For example, the input device 307 can be a mouse, a keyboard, a touch screen device, or a sensor device.

[0084] The above-mentioned network device can be a general network device or a dedicated network device. For example, it can be a desktop computer, a portable computer, a network server, etc., which is not limited in the present embodiment.

[0085] Next, the transmission indication method provided in the embodiment of the present application is explained in detail.

[0086] FIG4 is a flow chart of a transmission indication method provided in an embodiment of the present application. The method can be applied to the communication system described above. Referring to FIG4 , the method includes the following steps:

[0087] Step 401: A network device sends first indication information to a first terminal, and the first terminal receives the first indication information, where the first indication information is used to indicate whether the DRX and / or DTX functions of a first cell where the first terminal is located are enabled or disabled.

[0088] In an embodiment of the present application, before enabling or disabling the DRX function and / or DTX function of the first cell, the network device may first send first indication information to a first terminal in a non-connected state within the signal coverage of the first cell.

[0089] The first indication information may be used to indicate whether a DRX function and / or a DTX function of the first cell is enabled or disabled. The first cell may be any one of one or more cells provided by the network device. Furthermore, the first terminal refers to any terminal in a non-connected state within the signal coverage of the first cell, and there may be one or more first terminals.

[0090] Exemplarily, the first indication information may include cell information such as the identifier of the first cell and status indication information. The status indication information may include two bits, one bit for indicating the enable status of the DRX function, and one bit for indicating the enable status of the DTX function. For example, the high-order bit of the two bits is used to indicate the enable status of the DRX function, and the low-order bit is used to indicate the enable status of the DTX function. When the bit value is 1, it is used to indicate enablement, and when the bit value is 0, it is used to indicate disenablement. Based on this, when the status indication information is 00, it indicates that both the DRX function and the DTX function are disabled; when the status indication information is 01, it indicates that the DRX function is disabled and the DTX function is enabled; when the status indication information is 10, it indicates that the DRX function is enabled and the DTX function is disabled; when the status indication information is 11, it indicates that both the DRX function and the DTX function are enabled.

[0091] Optionally, the first indication information may not include cell information. In this case, the cell information may also be transmitted implicitly or explicitly in other ways, which is not limited in this embodiment of the present application.

[0092] Optionally, the status indication information in the first indication information may also only include a bit for indicating the enable status of the DRX function or a bit for indicating the enable status of the DTX function.

[0093] Optionally, the network device may indicate in a preconfigured manner that the status indication information in the first indication information only includes bits for indicating the enabled state of the DRX function, or only includes bits for indicating the enabled state of the DTX function, or includes both bits for indicating the enabled state of the DRX function and bits for indicating the enabled state of the DTX function.

[0094] Optionally, the network device may also indicate, according to the protocol provisions, that the status indication information in the first indication information only includes bits for indicating the enabled state of the DRX function, or only includes bits for indicating the enabled state of the DTX function, or includes both bits for indicating the enabled state of the DRX function and bits for indicating the enabled state of the DTX function.

[0095] Optionally, in an embodiment of the present application, the status indication information in the first indication information may be used to indicate activation of one of multiple cell DRX modes or configuration information and deactivation of other cell DRX modes or configuration information. The multiple cell DRX modes or configuration information are indicated by the network device before the first indication information is sent. A cell DRX mode or configuration information is used to indicate a configured cell DRX activation period and inactivation period.

[0096] Optionally, in an embodiment of the present application, the status indication information in the first indication information may also be used to activate one of multiple cell DTX modes or configuration information and deactivate other cell DTX modes or configuration information. The multiple cell DTX modes or configuration information are indicated by the network device before the first indication information is sent. A cell DTX mode or configuration information is used to indicate a configured cell DTX activation time period and inactivation time period.

[0097] Optionally, the first indication information may also be used to indicate a first reception mode, where the first reception mode is one of at least two C-DRX modes pre-configured by the first terminal. That is, in this embodiment of the present application, the network device may further indicate, through the first indication information, to the first terminal within the coverage of the first cell, the C-DRX mode to be adopted when the first terminal switches to the connected state.

[0098] Exemplarily, the first indication information may also include C-DRX mode indication information to indicate the first receiving mode. The C-DRX mode indication information may include one or more bits. For example, when the network device pre-configures two C-DRX modes for terminals accessing itself, the C-DRX mode indication information may include one bit. When the bit value is 0, it indicates that the first receiving mode adopted by the first terminal in the connected state is C-DRX mode 1. When the bit value is 1, it indicates that the first receiving mode adopted by the first terminal in the connected state is C-DRX mode 2. Optionally, the C-DRX mode indication information may also be an identifier of the C-DRX mode.

[0099] Optionally, as another example, the first indication information may also be used to indicate a second reception mode, where the second reception mode may be one of at least two idle DRX modes pre-configured by the first terminal. The idle DRX mode may be used to indicate the terminal's paging cycle and the location of its corresponding paging occasion (PO). That is, in an embodiment of the present application, the network device may also indicate, through the first indication information, to the first terminal within the coverage area of ​​the first cell, the mode in which the first terminal monitors POs, such as the cycle and location of POs.

[0100] Exemplarily, the first indication information may also include idle state DRX mode indication information or paging occasion indication information to indicate the second receiving mode. The idle state DRX mode indication information may include one or more bits. For example, when the network device pre-configures two idle state DRX modes for the terminal, the idle state DRX mode indication information may include one bit. When the bit value is 0, it indicates that the second receiving mode adopted by the non-connected terminal in the cell is idle state DRX mode 1 (or indicates that the non-connected terminal in the cell adopts paging occasion set 1 to receive paging). When the bit value is 1, it indicates that the second receiving mode adopted by the non-connected terminal in the cell is idle state DRX mode 2 (or indicates that the non-connected terminal in the cell adopts paging occasion set 2 to receive paging). Optionally, the idle state DRX mode indication information may also be an identifier of the idle state DRX mode.

[0101] In addition, in an embodiment of the present application, enabling the DRX function of the first cell means that the network device turns on the discontinuous reception function of the first cell, wherein the discontinuous reception function of the first cell means that the network device receives data during the activation time period within the DRX cycle of the first cell and does not receive data during the inactivation time period.

[0102] Disabling the DRX function of the first cell means that the network device turns off the discontinuous reception function of the first cell, that is, the network device can start receiving data on the first cell at any time.

[0103] Enabling the DTX function of the first cell means that the network device turns on the discontinuous transmission function of the first cell, wherein the discontinuous transmission function of the first cell means that the network device sends data during the activation time period within the DTX cycle of the first cell and does not send data during the inactive time period.

[0104] Disabling the DTX function of the first cell means that the network device turns off the discontinuous transmission function of the first cell, that is, the network device can start to send data on the first cell at any time.

[0105] FIG5 is a schematic diagram of enabling and disabling the DTX function of a cell provided by an embodiment of the present application. As shown in FIG5 , at time t1, the network device enables the DTX function of the cell. Thus, the DTX cycle of the cell begins at time t1. During the active time period of the DTX cycle, that is, from time t1 to time t2, the network device transmits data on the cell. During the inactive time period of the DTX cycle, that is, from time t2 to time t3, the network device does not transmit data on the cell. At time t3, the network device disables the DTX function of the cell. Then, starting from time t3, the network device can transmit data on the cell at any time.

[0106] In one possible implementation, the network device may send first indication information to the first terminal within a first time unit, where a time difference between the first time unit and a second time unit is less than a preset time threshold, and the second time unit is a time unit for sending the SSB. Accordingly, the first terminal may receive the first indication information in the first time unit.

[0107] Specifically, the second time unit is located before the first time unit, that is. After the network device sends the SSB in the second time unit, it sends the first indication information to the first terminal in the first time unit. The time difference between the first time unit and the second time unit can be the difference between the start time of the first time unit and the end time of the second time unit, or the difference between the start time of the first time unit and the start time of the second time unit. The time unit mentioned in the embodiment of the present application may include one or more time domain resources, which may be a time slot, a mini time slot or a subframe.

[0108] It should be noted that, for terminals in a non-connected state in the network, although the network device will not send service data to these terminals, the network device will still send SSB, system information block (SIB), PEIDCI and paging messages to these terminals. Among them, the transmission of SSB is not affected by the DTX mechanism of the network device, that is, regardless of whether the network device turns on the DTX function of the first cell, the network device will broadcast SSB at a fixed period according to the SSB broadcast mechanism. Based on this, in an embodiment of the present application, the first time unit for the network device to send the first indication information can be as close as possible to the second time unit for sending SSB, that is, the time difference between the first time unit and the second time unit can be less than the preset time threshold, so that the transmission time of the network device can be concentrated as much as possible, that is, the network device can complete the transmission in the shortest possible time, thereby turning off the transmission for as long a time period as possible to achieve better energy saving effect.

[0109] In addition, the preset time threshold may be pre-configured in the network device, and the size of the preset time threshold may be set as needed to ensure that the first time unit is as close as possible to the second time unit.

[0110] In an embodiment of the present application, the first indication information sent by the network device within the first time unit may be carried by a dedicated DCI. In this case, the first time unit may be a time domain resource allocated for sending the dedicated DCI. In this case, the network device may pre-send the location information of the first time unit to the first terminal. Alternatively, the first terminal may be pre-statically configured with the location information of the first time unit. Accordingly, the first terminal may monitor the dedicated DCI carrying the first indication information at the corresponding location based on the location information.

[0111] Optionally, when there is an existing DCI in the first time unit, the network device may also reuse the existing DCI in the first time unit to carry the first indication information. In this case, the first terminal may monitor the existing DCI carrying the first indication information at the corresponding position based on the location information of the existing DCI.

[0112] As an example, the existing DCI may be PEIDCI. That is, in an embodiment of the present application, the network device may reuse PEIDCI to carry the first indication information and send the PEIDCI to the first terminal within the PEI opportunity corresponding to the first terminal. In this case, the first time unit may include the PEI opportunity. For example, the first time unit is the PEI opportunity. Accordingly, the first terminal may monitor and receive the PEIDCI within its corresponding PEI opportunity.

[0113] Exemplarily, referring to FIG. 6 , the PEIDCI includes a paging indication field, a tracking reference signal (TRS) availability indication field, and a reserved field.

[0114] The paging indication field may include paging indication information corresponding to each subgroup in each of multiple paging occasions (POs), and the paging indication information is used to indicate whether a terminal belonging to a certain subgroup has a paging message to be received in the associated PO. For example, referring to Figure 6, the paging indication field includes paging indication information corresponding to multiple subgroups in PO1 to POn. The multiple subgroups include SG1 to SGm. Based on this, the first bit in the paging indication field is used to indicate the paging indication information corresponding to SG1 in PO1, the second bit is used to indicate the paging indication information corresponding to SG2 in PO1, and so on. The mth bit is used to indicate the paging indication information corresponding to SGm in PO1. Next, starting from the m+1th bit, the paging indication information corresponding to each subgroup in PO2 is displayed, and so on. On this basis, when a terminal receives PEIDCI, it can determine the bits corresponding to the PO associated with itself and the subgroup to which it belongs in the paging indication field. For example, assuming that the PO associated with the terminal is PO1 and the subgroup to which it belongs is SG2, it can be determined that the bit corresponding to the terminal in the paging indication field is the second bit. At this time, if the bit is the first value, it can be determined that the terminal has a paging message to be received on the next paging opportunity PO1 associated with itself. If the bit is the second value, it can be determined that the terminal has no paging message to be received on the next paging opportunity PO1 associated with itself. The first value can be 1 and the second value can be 0.

[0115] The TRS availability indication field is used to indicate to the terminal whether TRS is available, that is, to indicate whether the terminal can use TRS instead of SSB for downlink synchronization before receiving a paging message on PO.

[0116] The reserved field is a field whose use has not yet been defined. Based on this, in an embodiment of the present application, part or all of the reserved field in the PEIDCI can be used as a transmission indication field, and the first indication information is carried by the transmission indication field. For example, referring to Figure 6, the first indication information carried in the transmission indication field can be 01110, wherein the first two digits "01" indicate that the identifier of the first cell is 01, the middle two digits "11" indicate that both the DRX function and the DTX function are enabled, and the last digit "0" indicates that the first terminal uses C-DRX mode 1 to transmit data in the connected state.

[0117] As another example, the first indication information carried in the transmission indication field may be 110, where the first two bits "11" indicate that both the DRX function and the DTX function are enabled, and the last bit "0" indicates that the terminal uses C-DRX mode 1 to transmit data in the connected state. In this case, cell information such as the identifier of the first cell may be implicitly carried in the scrambling code of the PDCCH.

[0118] As another example, the first indication information carried in the transmission indication field may be 11, where "11" indicates that both the DRX function and the DTX function are enabled. In this case, cell information such as the identity of the first cell may be implicitly carried in the scrambling code of the PDCCH.

[0119] As another example, when the network device indicates through pre-configuration or protocol that the first indication information only includes bits for indicating the enable status of the cell DRX function, the first indication information carried in the transmission indication field may be 1. In this case, the first indication information is used to indicate that the cell DRX function is enabled. When the network device indicates through pre-configuration or protocol that the first indication information only includes bits for indicating the enable status of the cell DTX function, the first indication information carried in the transmission indication field may be 1. In this case, the first indication information is used to indicate that the cell DTX function is enabled. In this case, cell information such as the identifier of the first cell may be implicitly carried in the scrambling code of the PDCCH.

[0120] As another example, the first indication information carried in the transmission indication field may be 1101, where the first two bits "11" indicate that both the DRX function and the DTX function are enabled, and the third bit "0" indicates that the terminal uses C-DRX mode 1 to transmit data in the connected state. The last bit "1" is used to instruct the terminal to use idle DRX mode 2 to transmit data in the non-connected state. In this case, cell information such as the identity of the first cell may be implicitly carried in the scrambling code of the PDCCH.

[0121] As another example, the first indication information carried in the transmission indication field can be 111001, where the first two digits "11" indicate that both the DRX function and the DTX function are enabled; the "1" in the middle two digits "10" indicates that the network device will use cell DRX mode 2 to receive data, and the "0" indicates that the network device will use cell DTX mode 1 to send data; the "0" in the last two digits "01" indicates that the terminal uses C-DRX mode 1 to transmit data in the connected state, and the "1" indicates that the terminal uses idle DRX mode 2 to transmit data in the unconnected state. In this case, cell information such as the identity of the first cell may be implicitly carried in the scrambling code of the PDCCH.

[0122] Optionally, when using the reserved field of PEIDCI to carry the first indication information, considering that PEIDCI also includes other indication fields, in order to enable the first terminal to better parse the first indication information from the PEIDCI, the network device may also send configuration information to the first terminal in advance before sending the first indication information. The configuration information is used to indicate the starting position and length of the transmission indication field carrying the first indication information in the PEIDCI. On this basis, after the first terminal subsequently receives the PEIDCI at its corresponding PEI opportunity, it can determine the position of the transmission indication field in the PEIDCI according to the starting position and length indicated by the configuration information, and obtain the first indication information from the transmission indication field.

[0123] For example, as can be seen from the above description, for terminals in a non-connected state, the network device will send SIBs to these terminals.

[0124] Based on this, in an embodiment of the present application, the network device may carry the configuration information in the SIB and send it to the first terminal.

[0125] The configuration information may include an offset value between the transmission indication field and the first bit in the PEIDCI, which indicates the starting position of the transmission indication field in the PEIDCI. In addition, the configuration information may also include the number of bits in the transmission indication field to indicate the length of the transmission indication field.

[0126] In another possible implementation, the network device may send the first indication information within a third time unit whose time difference from the second time unit is not less than a preset time threshold. Correspondingly, the first terminal may receive the first indication information within the third time unit.

[0127] The network device may carry the first indication information via a dedicated DCI. In this case, the third time unit is the time domain resource allocated for sending the dedicated DCI. In this case, the network device may pre-send the location information of the third time unit to the first terminal. Alternatively, the first terminal may be pre-statically configured with the location information of the third time unit. Accordingly, the first terminal may monitor the dedicated DCI carrying the first indication information at the corresponding location based on the location information.

[0128] Optionally, the network device may reuse an existing DCI to carry the first indication information. In this case, the third time unit may be a time domain resource for sending the corresponding DCI. In this case, the first terminal may receive the corresponding DCI on the corresponding time domain resource and obtain the first indication information therefrom.

[0129] As an example, the above-mentioned existing DCI can be PEIDCI. In this case, the third time unit can be the PEI opportunity, and the first terminal can listen to the PEIDCI carrying the first indication information at the PEI opportunity. Among them, the relevant implementation method of carrying the first indication information by PEIDCI can refer to the introduction in the previous article, which will not be repeated here. In summary, it can be seen that in a possible implementation method of an embodiment of the present application, no matter what the time difference between the PEI opportunity and the second time unit is, that is, no matter whether the time difference between the two times is greater than, less than or equal to the preset time threshold, the network device can reuse PEIDCI to carry the first indication information.

[0130] Optionally, as can be seen from the above introduction, for terminals in a non-connected state, the network device will send paging messages to these terminals. The paging message includes a paging physical downlink control channel (PDCCH) and a paging physical downlink shared channel (PDSCH). The paging PDCCH can be used to carry control information indicating the paging PDSCH. Based on this, in an embodiment of the present application, the network device can use the reserved field in the paging PDCCH to carry the first indication information. Accordingly, the first terminal can monitor and receive the PDCCH during the monitoring period of the paging PDCCH, and obtain the first indication information from the PDCCH.

[0131] Optionally, the paging PDSCH includes a medium access control element (MAC-CE), which can be used to carry control information of the MAC layer. Based on this, in an embodiment of the present application, the network device can also use the MAC-CE in the paging PDSCH to carry the first indication information. Accordingly, the first terminal can monitor and receive the PDSCH during the monitoring period of the paging PDSCH and obtain the first indication information from the MAC-CE of the PDSCH.

[0132] It should be noted that, when reusing the currently existing DCI to carry the first indication information, since the existing DCI also carries other control information, in an embodiment of the present application, the network device may also refer to the aforementioned method of pre-sending configuration information to the first terminal to indicate the position of the first indication information in the corresponding DCI, thereby facilitating the first terminal to obtain the first indication information from the corresponding DCI.

[0133] Step 402: The first terminal transmits other indication information or data based on the first indication information.

[0134] In the embodiment of the present application, transmission may include at least one of sending and receiving.

[0135] After receiving the first indication information, the first terminal may transmit other indication information or data on the first cell based on the first indication information.

[0136] Exemplarily, if the first indication information indicates that the DRX function of the first cell is enabled, the first terminal sends uplink data during the activation time period of the DRX cycle of the first cell, and does not send uplink data during the inactivation time period.

[0137] If the DRX function of the first cell is enabled, it means that the network device has turned on the discontinuous reception function of the first cell. In this case, the network device will receive data on the first cell during the activation time period of the DRX cycle of the first cell, and will not receive data on the first cell during the inactivation time period. Based on this, if the first terminal has data to be sent to the network device, the first terminal can determine the position of the DRX cycle of the first cell, the position of the activation time period within the DRX cycle, and the position of the inactivation time period based on the pre-configured DRX parameters of the network device. Afterwards, based on the position of the DRX cycle and the position of the activation time period and inactivation time period within the DRX cycle, the uplink data to be sent is sent to the network device on the first cell during the activation time period, and the uplink data is not sent on the first cell during the inactivation time period.

[0138] Optionally, if multiple cell DRX modes or configuration information are pre-configured in the first terminal, and the first indication information also indicates the target DRX mode or configuration information to be adopted by the network device, then when the first terminal has data to be sent to the network device, it can obtain the DRX parameters corresponding to the target DRX mode or configuration information, and then based on the position of the DRX cycle indicated by the DRX parameters, the position of the activation time period and the inactivation time period within the DRX cycle, send the uplink data to be sent to the network device on the first cell during the activation time period, and do not send the uplink data on the first cell during the inactivation time period.

[0139] Optionally, if the first indication information indicates that the DTX function of the first cell is enabled, downlink data is received during the activation time period of the DTX cycle of the first cell, and downlink data is not received during the inactivation time period.

[0140] If the DTX function of the first cell is enabled, it means that the network device has turned on the discontinuous transmission function of the first cell. In this case, the network device will send downlink data or other indication information on the first cell during the activation time period of the DTX cycle of the first cell, and will not send downlink data or other indication information on the first cell during the inactivation time period. Based on this, the first terminal can determine the position of the DTX cycle of the first cell, the position of the activation time period within the DTX cycle, and the position of the inactivation time period according to the pre-configured DTX parameters of the network device. Afterwards, according to the position of the DTX cycle, the position of the activation time period and the inactivation time period within the DTX cycle, the downlink data or other indication information is monitored on the first cell during the activation time period, and the downlink data or other indication information is not monitored on the first cell during the inactivation time period. The downlink data may include the PDSCH in the paging message, and other indication information may include the paging PDDCH.

[0141] Optionally, if multiple cell DTX modes or configuration information are pre-configured in the first terminal, and the first indication information also indicates the target DTX mode or configuration information to be adopted by the network device, the first terminal can obtain the DTX parameters corresponding to the target DTX mode or configuration information, and then based on the position of the DTX cycle indicated by the DTX parameter, the position of the activation time period and the inactivation time period within the DTX cycle, listen to downlink data or other indication information on the first cell during the activation time period, and do not listen to downlink data or other indication information on the first cell during the inactivation time period.

[0142] Optionally, if the first indication information is also used to indicate a first receiving mode, the first terminal may further receive downlink data or other indication information based on the first receiving mode after switching from the non-connected state to the connected state.

[0143] As can be seen from the introduction in the aforementioned step 401, the first indication information can also be used to indicate which C-DRX mode the first terminal uses to transmit data with the network device after switching to the connected state. Based on this, after the first terminal receives the first indication information, if the first terminal reestablishes a radio resource control (RRC) connection with the network device, the first terminal switches from the non-connected state to the connected state. In this case, the first terminal can use the first receiving mode indicated in the first indication information to receive downlink data or other indication information sent by the network device. The first receiving mode is one of at least two C-DRX modes pre-configured by the first terminal.

[0144] Specifically, the first terminal can determine the position of its own C-DRX cycle, the position of the activation time period within the C-DRX cycle, and the position of the inactivation time period based on the pre-configured C-DRX parameters of the first receiving mode. Afterwards, during the activation time period of the C-DRX cycle, the first terminal monitors and receives downlink data or other indication information sent by the network device, while during the inactivation time period of the C-DRX cycle, the first terminal does not monitor downlink data or other indication information.

[0145] Optionally, if the first indication information further indicates a second receiving mode, the first terminal may also monitor the PO based on the second receiving mode in the non-connected state to receive the paging message.

[0146] In an embodiment of the present application, a network device may send first indication information to a terminal in a non-connected state to indicate whether to enable or disable the DRX and / or DTX functions of a first cell in which the terminal is located. In this way, the terminal in the non-connected state may transmit data or other indication information with the network device based on the first indication information. Therefore, it can be seen that the embodiment of the present application enables indicating cell DRX and / or cell DTX to the terminal in the non-connected state, thereby reducing the power consumption of the network device when transmitting data with the terminal in the non-connected state.

[0147] In addition, in an embodiment of the present application, the first time unit used by the network device to send the first indication information can be as close as possible to the second time unit used to send SSB. In this way, the sending time of the network device can be concentrated as much as possible, that is, the network device can complete the sending in the shortest possible time, thereby shutting down the sending for the longest possible period of time to achieve better energy saving effects.

[0148] Finally, in an embodiment of the present application, the network device can reuse the PEIDCI sent at the FEI opportunity to carry the first indication information, without redefining a dedicated DCI to carry the first indication information, thereby saving DCI overhead, and the terminal can obtain the first indication information by monitoring the PEI opportunity, without having to monitor the first indication information at other times, thereby saving the power consumption of the terminal.

[0149] Based on the transmission indication method provided in the above embodiment, the embodiment of the present application further provides a detailed process of transmitting an indication between a network device and a first terminal. Referring to FIG7 , the process includes the following steps:

[0150] Step 701: The network device sends configuration information to the first terminal. The configuration information is used to indicate the starting position and length of the transmission indication field in the PEIDCI.

[0151] Step 702: The network device sends PEIDCI to the first terminal within the PEI opportunity corresponding to the first terminal, and the transmission indication field of the PEIDCI includes first indication information.

[0152] Step 703: After receiving the PEIDCI in its corresponding PEI opportunity, the first terminal obtains the first indication information from the PEIDCI based on the starting position and length of the transmission indication field indicated by the configuration information.

[0153] Step 704: The first terminal transmits other indication information or data to the network device based on the first indication information.
