The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and the accompanying text are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of this application to those skilled in the art by reference to specific embodiments.

[0115] Implementation Methods of the Application

[0116] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0117] It should be noted that, in this document, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. In addition, components, features, and elements with the same name in different embodiments of the present application may have the same meaning or different meanings, and their specific meanings need to be determined by their explanation in the specific embodiment or further combined with the context of the specific embodiment.

[0118] It should be understood that although the terms "first," "second," "third," etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are used solely to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the term "if," as used herein, may be interpreted as "upon," "when," or "in response to a determination." Furthermore, as used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context indicates otherwise. It should be further understood that the terms "comprising" and "including" indicate the presence of the recited features, steps, operations, elements, components, items, types, and / or groups, but do not preclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, types, and / or groups. The terms "or," "and / or," "including at least one of the following," etc., as used herein, may be interpreted as inclusive, meaning any one or any combination. For example, “comprising at least one of the following: A, B, C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”; and for another example, “A, B or C” or “A, B and / or C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”. An exception to this definition will occur only when a combination of elements, functions, steps or operations are inherently mutually exclusive in some manner.

[0119] It should be understood that, although the various steps in the flowchart in the embodiment of the present application are shown in sequence according to the indication of the arrows, these steps are not necessarily performed in sequence in the order indicated by the arrows. Unless clearly stated herein, the execution of these steps is not strictly limited in order, and they can be performed in other orders. Moreover, at least a portion of the steps in the figure may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily performed at the same time, but can be performed at different times, and their execution order is not necessarily performed in sequence, but can be performed in turn or alternately with at least a portion of other steps or sub-steps or stages of other steps.

[0120] As used herein, the words "if" and "if" may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to the determination" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)," depending on the context.

[0121] It should be noted that in this article, step codes such as S10 and S20 are used for the purpose of expressing the corresponding content more clearly and concisely, and do not constitute a substantial limitation on the order. When implementing the step, those skilled in the art may execute S20 first and then S10, etc., but these should all be within the scope of protection of this application.

[0122] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0123] In the subsequent description, the use of suffixes such as "module", "component" or "unit" to represent elements is only for the purpose of facilitating the description of the present application and has no specific meaning. Therefore, "module", "component" or "unit" can be used interchangeably.

[0124] The communication equipment mentioned in this application can be a terminal device (such as a mobile terminal, specifically a mobile phone) or a network device (such as a base station). The specific reference needs to be clarified in the context.

For example, the terminal device described in this application may include smart terminals such as mobile phones, tablet computers, laptop computers, PDAs, portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, and fixed terminals such as digital TVs and desktop computers.

[0126] The subsequent description will be made by taking a mobile terminal as an example. It will be understood by those skilled in the art that, in addition to components specifically used for mobile purposes, the configuration according to the embodiments of the present application can also be applied to fixed-type terminals.

[0127] Please refer to Figure 1, which is a schematic diagram of the hardware structure of a mobile terminal for implementing various embodiments of the present application. The mobile terminal 100 may include components such as an RF (Radio Frequency) unit 101, a WiFi module 102, an audio output unit 103, an A / V (Audio / Video) input unit 104, a sensor 105, a display unit 106, a user input unit 107, an interface unit 108, a memory 109, a processor 110, and a power supply 111. Those skilled in the art will understand that the mobile terminal structure shown in Figure 1 does not limit the mobile terminal. The mobile terminal may include more or fewer components than shown, or may combine certain components, or arrange the components differently.

[0128] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:

[0129] The RF unit 101 can be used to send and receive signals during information transmission or calls. Specifically, it receives downlink information from the base station and transmits it to the processor 110 for processing. It also transmits uplink data to the base station. Typically, the RF unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, and other components. Furthermore, the RF unit 101 can communicate with the network and other devices via wireless communication. The above-mentioned wireless communications can use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (Code Division Multiple Access 2000), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-SyncLronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution), TDD-LTE (Time Division Duplexing-Long Term Evolution), 5G or 6G, etc.

[0130] WiFi is a short-range wireless transmission technology. A mobile terminal, through WiFi module 102, enables users to send and receive emails, browse web pages, and access streaming media, providing wireless broadband Internet access. Although FIG1 illustrates WiFi module 102, it is understood that it is not a required component of the mobile terminal and can be omitted as needed without altering the essence of the invention.

[0131] The audio output unit 103 can convert audio data received by the RF unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the mobile terminal 100 is in a call signal reception mode, a talk mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Furthermore, the audio output unit 103 can also provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output unit 103 may include a speaker, a buzzer, or the like.

[0132] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processing unit (GPU) 1041 and a microphone 1042. The GPU 1041 processes image data of still images or videos captured by an image capture device (e.g., a camera) in video capture mode or image capture mode. The processed image frames may be displayed on the display unit 106. The image frames processed by the GPU 1041 may be stored in the memory 109 (or other storage medium) or transmitted via the RF unit 101 or the WiFi module 102. The microphone 1042 may receive sound (audio data) in operating modes such as a phone call mode, a recording mode, and a voice recognition mode, and may process such sound into audio data. In the phone call mode, the processed audio (voice) data may be converted into a format that can be transmitted to a mobile communication base station via the RF unit 101. The microphone 1042 may implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0133] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 1061 and / or the backlight when the mobile terminal 100 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 recognize the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured in the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be described here.

[0134] The display unit 106 is used to display information input by the user or information provided to the user. The display unit 106 may include a display panel 1061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0135] The user input unit 107 can be used to receive input digital or character information, and to generate key signal input related to the user settings and function control of the mobile terminal. Optionally, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect user touch operations on or near it (such as operations performed by the user using a finger, stylus, or any other suitable object or accessory on or near the touch panel 1071) and drive the corresponding connection device according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch direction and detects the signal generated 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 it into touch point coordinates, which are then sent to the processor 110. It can also receive commands sent by the processor 110 and execute them. In addition, the touch panel 1071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072. Optionally, the other input devices 1072 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, power keys, etc.), a trackball, a mouse, a joystick, etc., and the specifics are not limited here.

[0136] Optionally, the touch panel 1071 may overlay the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. The processor 110 then provides a corresponding visual output on the display panel 1061 based on the type of touch event. Although in FIG1 , the touch panel 1071 and the display panel 1061 are shown as two separate components to implement the input and output functions of the mobile terminal, in some embodiments, the touch panel 1071 and the display panel 1061 may be integrated to implement the input and output functions of the mobile terminal, which is not limited to this specific embodiment.

[0137] The interface unit 108 serves as an interface through which at least one external device can be connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device with an identification module, an audio input / output (I / O) port, a video I / O port, a headphone port, etc. The interface unit 108 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal 100 and an external device.

[0138] Memory 109 can be used to store software programs and various data. Memory 109 may primarily include a program storage area and a data storage area. Optionally, the program storage area may store an operating system and at least one application required for a function (such as a sound playback function or an image playback function); the data storage area may store data generated based on the use of the mobile phone (such as audio data, a phone book, etc.). Furthermore, memory 109 may include high-speed random access memory and non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0139] Processor 110 is the control center of the mobile terminal, connecting all components of the mobile terminal using various interfaces and circuits. By running or executing software programs and / or modules stored in memory 109 and accessing data stored in memory 109, it executes various functions of the mobile terminal and processes data, thereby providing overall monitoring of the mobile terminal. Processor 110 may include one or more processing units; preferably, processor 110 may integrate an application processor and a modem processor. Optionally, 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 110.

[0200] Optionally, the number of bits of the first information transmission period dynamic adjustment field is related to the multiplexing mode of the synchronization signal block and the control resource set #0.

[0201] Optionally, for SSB and CORESET#0 multiplexing mode 1, the number of bits of the first information transmission period dynamic adjustment field in the downlink control information can be 2, and each code point corresponds to a value in the set L={0,1,2}.

[0202] Optionally, for SSB and CORESET#0 multiplexing mode 2 or 3, the number of bits of the first information transmission period dynamic adjustment field in the downlink control information can be 4, and each code point corresponds to a value in the set L = {-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5}.

[0203] Optionally, the activation or deactivation indication field of the first information is used to indicate whether the base station transmits the first information at one or more first information repetition period opportunities.

[0204] Optionally, the method further comprises at least one of the following:

[0208] During the first preset time period and / or the second preset time period, the transmission mode is to dynamically adjust the period to transmit the first information;

[0209] During the first preset time period, the first information is not transmitted.

[0210] Optionally, taking the first information as SIB1 information, the terminal device as UE, and the network device as a base station as an example, the above transmission modes are as follows:

[0211] Optionally, for on-demand transmission of the first information:

[0212] In one implementation, if the UE is in the RRC Inactive state or the RRC Idle state:

[0213] Then, during the second preset time period, the base station adopts a normal periodic transmission method of transmitting the first information to transmit SIB1 information; and during the first preset time period, the base station adopts an on-demand transmission method of transmitting the first information to transmit SIB1 information. Specifically, during the cell DTX inactive time, the base station transmits SIB1 information only after receiving the uplink wake-up signal of the terminal device and at the transmission timing that meets the first preset rule; and during the cell DTX active time, the base station transmits SIB1 information according to the traditional SIB1 repeated transmission period.

[0214] Optionally, the traditional SIB1 period is 160ms.

[0215] Optionally, for SSB and CORESET#0 multiplexing mode 1, the traditional SIB1 repetition transmission period is 20ms within 160ms.

[0216] Optionally, for SSB and CORESET#0 multiplexing mode 2 or 3, within 160ms, the traditional SIB1 repetition transmission period is the same as the period of the SSB associated with SIB1.

[0217] If the UE is in the RRC Connected state:

[0218] Then, during the second preset time period, the base station adopts a normal periodic transmission method of transmitting the first information to transmit SIB1 information; and during the first preset time period, the base station adopts an on-demand transmission method of transmitting the first information to transmit SIB1 information. Specifically, during the cell DTX inactive time, the base station transmits SIB1 information only after receiving an uplink wake-up signal and at a transmission timing that meets the first preset rule; and during the cell DTX active time, the base station transmits SIB1 information according to the traditional SIB1 repeated transmission period.

[0219] Optionally, if SIB1 transmission is not performed in a certain SIB1 repetition transmission period, the DCI scheduling this SIB1 does not need to be sent to the terminal. Specifically, if SIB1 transmission is required in a certain SIB1 repetition transmission period, the base station needs to send the DCI scheduling this SIB1 to the terminal before the SIB1 transmission; if SIB1 transmission is not performed in a certain SIB1 repetition transmission period, the base station does not need to send the DCI corresponding to this SIB1 to the terminal.

[0220] In another implementation, if the UE is in the RRC Inactive state or the RRC Idle state:

[0221] Then, within the first preset time period and the second preset time period, the base station adopts the transmission method of transmitting the first information on demand to transmit SIB1 information. Specifically, during the cell DTX activation time and the non-activation time, the base station transmits SIB1 information only after receiving the uplink wake-up signal and at the transmission timing that meets the first preset rule.

[0222] Similarly, if the UE is in the RRC Connected state:

[0223] Then, within the first preset time period and the second preset time period, the base station adopts the transmission method of transmitting the first information on demand to transmit SIB1 information. Specifically, during the cell DTX activation time and the non-activation time, the base station transmits SIB1 information only after receiving the uplink wake-up signal and at the transmission timing that meets the first preset rule.

[0224] Optionally, when there is no first information transmission (such as no SIB1 transmission):

[0225] If the UE is in the RRC Inactive state or the RRC Idle state:

[0226] Then, during the second preset time period, the base station adopts a transmission method without first information transmission to transmit SIB1 information; and during the first preset time period, the base station does not perform SIB1 transmission in all SIB1 repetition transmission period opportunities. Specifically, during the cell DTX activation time, the base station instructs the network device whether to perform SIB1 transmission in the corresponding SIB1 repetition transmission period by sending a DCI format 1_0 containing an activation or deactivation indication field of the newly added first information to the terminal. If the number of activation or deactivation indication fields for the first information in the DCI format 1_0 is 1, a bit of 1 represents that there is SIB1 transmission in the current SIB1 repetition transmission period opportunity, and a bit of 0 represents that there is no SIB1 transmission in the current SIB1 repetition transmission period opportunity.

[0227] If the UE is in the RRC Connected state:

[0228] Then, during the second preset time period, the base station transmits SIB1 information in a transmission mode without first information transmission; and during the first preset time period, the base station does not transmit SIB1 in all SIB1 repeated transmission period opportunities.

[0229] Optionally, if the UE is in the RRC Inactive state, the RRC Idle state or the RRC Connected state, the base station may also adopt a transmission mode without first information transmission to transmit SIB1 information in both the first preset time period and the second preset time period.

[0230] Optionally, if the UE is in the RRC Inactive state, RRC Idle state or RRC Connected state, the base station uses the normal periodic transmission method of transmitting the first information to transmit SIB1 information within the second preset time period; and within the first preset time period, the base station uses the transmission method without first information transmission to transmit SIB1 information.

[0231] Optionally, for the RRC Connected state, in addition to sending a DCI containing an activation or deactivation indication field of the newly added first information to the terminal to indicate whether the network device performs SIB1 transmission in the corresponding SIB1 repetition transmission period; the base station can also indicate whether the network device performs SIB1 transmission in the corresponding SIB1 repetition transmission period by sending an RRC message containing an activation or deactivation indication field of the newly added first information to the terminal.

[0232] Optionally, for dynamically adjusting the periodic transmission SIB1:

[0233] In one implementation, if the UE is in the RRC Inactive state or the RRC Idle state:

[0234] During both the first and second preset time periods, the base station transmits SIB1 information using a transmission method that dynamically adjusts the first information transmission period. Specifically, during the cell DTX activation time and the cell DTX inactivation time, the base station transmits a DCI format 1_0 containing a newly added first information transmission period dynamic adjustment field to the terminal, thereby instructing the network device to repeat the transmission period in subsequent SIB1 transmissions.

[0235] Optionally, the number of bits of the first information transmission period dynamic adjustment field in DCI format 1_0 is related to the multiplexing mode of SSB and CORESET#0.

[0236] Optionally, for SSB and CORESET#0 multiplexing mode 1, the number of bits of the first information transmission period dynamic adjustment field in DCI format 1_0 can be 2, and each code point corresponds to a value in the set L={0,1,2}, for example, bit '00 corresponds to the value 0 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H=20ms*2^0; '01 corresponds to the value 1 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H=20ms*2^1; '10' corresponds to the value 2 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H=20ms*2^2, and so on.

[0237] Optionally, for SSB and CORESET#0 multiplexing mode 2 or 3, the number of indication bits of the first information transmission period dynamic adjustment field in DCI format 1_0 can be 4, and each code point corresponds to a value in the set L = {-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5}, for example, bit '00 corresponds to the value -5 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H = SSB period * 2^(-5); '01 corresponds to the value -4 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H = SSB period * 2^(-4), and so on.

[0238] Optionally, for SSB and CORESET#0 multiplexing mode 2 or 3, the adjusted repetition transmission period H of SIB1 is not less than 5ms and not more than 160ms. If the value after SSB period * 2^L1 is less than 5ms, the adjusted repetition transmission period of SIB1 is 5ms; similarly, if the value after SSB period * 2^L is greater than 160ms, the adjusted repetition transmission period of SIB1 is 160ms, where L1 is any value in the set L.

[0239] If the UE is in the RRC Connected state:

[0240] In the first preset time period and the second preset time period, the base station transmits the SIB1 information using a transmission method of dynamically adjusting the period for transmitting the first information. Specifically, during the cell DTX activation time and the cell DTX inactivation time, the base station dynamically indicates the adjusted SIB1 repetition transmission period to the UE through an RRC message or DCI format 1_0.

[0241] Optionally, the RRC message may directly indicate the adjusted repetitive transmission period of SIB1, for example, the RRC message directly indicates that the repetitive transmission period of SIB1 is adjusted to 5ms, 160ms, etc.

[0242] Optionally, the RRC message may also indicate that the adjusted retransmission period of SIB1 is a multiple of the current SIB1 retransmission period. For example, the retransmission period of SIB1 configured in the RRC message is adjusted to M times or 2^N times the current SIB1 retransmission period, where M and N are positive integers.

[0243] Optionally, the repetition transmission period of SIB1 in the downlink control information may also be adjusted to M times or 2^N times the repetition transmission period of the current SIB1.

[0244] The following takes the example of adjusting the repetition transmission period of SIB1 in the downlink control information to 2^N times the repetition transmission period of the current SIB1 as an example.

[0245] Optionally, the number of bits of the first information transmission period dynamic adjustment field in DCI format 1_0 is related to the multiplexing mode of SSB and CORESET#0.

[0246] Optionally, for SSB and CORESET#0 multiplexing mode 1, the number of bits of the first information transmission period dynamic adjustment field in DCI format 1_0 can be 2, and each code point corresponds to a value in the set L={0,1,2}, for example, bit '00 corresponds to the value 0 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H=20ms*2^0; '01 corresponds to the value 1 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H=20ms*2^1; '10' corresponds to the value 2 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H=20ms*2^2, and so on.

[0247] Optionally, for SSB and CORESET#0 multiplexing mode 2 or 3, the number of bits of the first information transmission period dynamic adjustment field in DCI format 1_0 can be 4, and each code point corresponds to a value in the set L = {-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5}, for example, bit '00 corresponds to the value -5 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H = SSB period * 2^(-5); '01 corresponds to the value -4 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H = SSB period * 2^(-4), and so on.

[0248] Optionally, for SSB and CORESET#0 multiplexing mode 2 or 3, the traditional SIB1 repetition transmission period H is not less than 5ms and not more than 160ms. If the value after SSB period * 2^L1 is less than 5ms, the repetition transmission period of SIB1 is 5ms; similarly, if the value after SSB period * 2^L1 is greater than 160ms, the repetition transmission period of SIB1 is 160ms, where L1 is any value in the set L.

[0249] In another implementation, if the UE is in the RRC Inactive state, RRC Idle state, or RRC Connected state:

[0250] During the second preset time period, the base station transmits SIB1 information using a transmission method of dynamically adjusting the periodic transmission of the first information; during the first preset time period, the base station does not transmit SIB1 during all SIB1 repeated transmission periodic opportunities.

[0251] Optionally, if the UE is in the RRC Inactive state, RRC Idle state or RRC Connected state, then within the second preset time period, the base station uses a transmission method of dynamically adjusting the periodic transmission of the first information to transmit SIB1 information; and within the first preset time period, the base station uses a transmission method without first information transmission to transmit SIB1 information.

[0252] Optionally, if the UE is in the RRC Inactive state, RRC Idle state or RRC Connected state, within the first preset time period, the base station uses a transmission method of dynamically adjusting the periodic transmission of the first information to transmit SIB1 information; and within the second preset time period, the base station uses a transmission method of normally periodically transmitting the first information to transmit SIB1 information.

[0253] Optionally, if the UE is in the RRC Inactive state, RRC Idle state or RRC Connected state, then within the second preset time period, the base station uses a transmission method of dynamically adjusting the periodic transmission of the first information to transmit SIB1 information; and within the first preset time period, the base station uses a transmission method without first information transmission to transmit SIB1 information.

[0254] Optionally, if the UE is in the RRC Inactive state, RRC Idle state or RRC Connected state, within the first preset time period, the base station uses a transmission method of dynamically adjusting the periodic transmission of the first information to transmit SIB1 information; and within the second preset time period, the base station uses a transmission method without first information transmission to transmit SIB1 information.

[0255] Optionally, the above RRC states and first information transmission modes may be combined arbitrarily.

[0256] Optionally, the DCI format 1_0 further includes at least one of the following:

[0257] Frequency domain resource allocation field, the number of bits it accounts for is in is the size of CORESET#0;

[0263] Optionally, if it is known that the base station does not send SIB1 in a certain SIB1 repetition transmission period, the terminal device does not need to decode the DCI for SIB1 scheduling corresponding to the repetition period.

[0264] In the technical solution of this embodiment, the network device sends the first information based on the transmission mode determined by the second information. In a multi-carrier scenario, the number of transmissions of the first information can be effectively reduced, thereby saving network energy consumption and / or reducing operating costs.

[0265] Second embodiment

[0266] Based on the above embodiments, a second embodiment of the present application proposes a transmission method. In this embodiment, the uplink wake-up signal that triggers SIB1 transmission is specifically described.

[0267] Optionally, the network device sends the first information in a transmission manner determined based on at least one of a radio resource control state, a first preset time period, and a second preset time period.

[0268] Optionally, if the transmission mode determined by the network device based on at least one of the radio resource control state, the first preset time period and the second preset time period is on-demand transmission of the first information.

[0269] Optionally, the on-demand transmission of the first information is: after receiving the uplink wake-up signal, the network device transmits the first information at a transmission timing when the first information meets a first preset rule.

[0270] Optionally, the uplink wake-up signal is sent by the terminal device according to actual service requirements. Furthermore, triggering the transmission of the first information through the uplink wake-up signal can effectively reduce the number of transmissions of the first information and save network energy consumption.

[0271] Optionally, the uplink wake-up signal includes at least one of the following:

[0272] The uplink wake-up signal is a periodic signal;

[0273] The uplink wake-up signal may be a pseudo-random sequence related to at least one of a radio frame number, a time slot number, and a cell identity;

[0274] The uplink wake-up signal may also be a fixed random access preamble sequence, that is, a reserved preamble in a random access preamble set. For example, the 64 preambles used for contention random access may be classified, and a portion of the random access preambles used for other purposes may be reserved as an uplink wake-up signal (WUS). For example, the preamble sequence index used as the uplink wake-up signal may also be directly specified.

[0275] Optionally, the uplink wake-up signal is received on a non-anchor carrier.

[0276] Optionally, the reception timing and / or frequency domain position of the uplink wake-up signal is determined by high-layer information on an anchor carrier associated with the non-anchor carrier, as shown in FIG6 .

[0277] Optionally, the time domain position of the uplink wake-up signal includes at least one of the following:

[0278] If the uplink wake-up signal is a preamble for random access, the timing of sending the uplink wake-up signal is the same as the timing of sending Msg1;

[0279] If the uplink wake-up signal is a newly defined pseudo-random sequence, the timing of sending the uplink wake-up signal can be a valid uplink symbol with a time slot offset length of not less than X before the timing of the last reception of the first information after the uplink wake-up signal, where X is a positive integer, as shown in Figure 7.

[0280] If the uplink wake-up signal is a newly defined pseudo-random sequence, the uplink wake-up signal may be transmitted on a valid uplink symbol that is no less than Z time slot offsets before the Yth time slot at which the first information is to be received after the uplink wake-up signal, where both Y and Z are positive integers. Specifically, taking SIB1 as an example, Z = X + SIB1 repetition transmission period (ms) * (2^u) * Y time slot offsets, as shown in FIG8 , where u is the subcarrier spacing of SIB1.

[0281] Optionally, the value of u may refer to the following Table 1:

[0282] Table 1

[0283] Optionally, the valid uplink symbol means that there are enough continuous uplink symbols in the time slot for uplink wake-up signal transmission.

[0284] Optionally, with respect to the frequency domain position of the uplink wake-up signal, the bandwidth occupied by the uplink wake-up signal is the same as the bandwidth of CORESET#0.

[0285] Optionally, the first preset time period is an inactive time period for discontinuous transmission of the cell.

[0286] Optionally, the second preset time period is an activation time of discontinuous transmission of the cell.

[0295] Optionally, the non-anchor carrier and the anchor carrier may be in-band carriers.

[0296] Optionally, if it is known that the base station does not send SIB1 in a certain SIB1 repetition transmission period, the terminal device does not need to decode the DCI for SIB1 scheduling corresponding to the repetition period.

[0297] In the technical solution of this embodiment, the network device determines, based on the second information, to use an on-demand transmission method to transmit the first information. Specifically, the base station transmits the first information only after receiving an uplink wake-up signal. This effectively reduces the number of transmissions of the first information, saving network energy consumption and / or reducing operating costs.

[0298] Third embodiment

[0299] Based on any of the above embodiments, the third embodiment of the present application proposes a transmission method, in which the terminal device sends an uplink wake-up signal to the network device to trigger the network device to send the first information in an on-demand transmission mode.

[0300] Optionally, in response to receiving the uplink wake-up signal, the network device transmits the first information at a transmission timing when the first information meets a first preset rule.

[0301] Optionally, satisfying the first preset rule includes at least one of the following:

[0302] The transmission opportunity is at least X time slots after the time slot in which the uplink wake-up signal is sent, where X is a positive integer;

[0303] The position of not less than X time slots after the uplink wake-up signal overlaps with the time slot of the most recent first information retransmission opportunity after the uplink wake-up signal;

[0304] The transmission opportunity is at least Z time slots after the time slot in which the uplink wake-up signal is sent, where Z is a positive integer;

[0305] The position of not less than Z time slots after the uplink wake-up signal overlaps with the time slot of the Yth time when the first information is repeatedly transmitted closest to the uplink wake-up signal, and both Z and Y are positive integers.

[0306] Optionally, the on-demand transmission mode of the first information may be within a first preset time period and / or a second preset time period.

[0307] Optionally, the first preset time period is an inactive time period for discontinuous transmission of the cell.

[0308] Optionally, the second preset time period is an activation time of discontinuous transmission of the cell.

[0309] Optionally, taking the first information as SIB1 information and the network device as a base station as an example:

[0310] Assuming that the transmission mode of transmitting the first information on demand is only within the first preset time period mentioned above, the base station transmits SIB1 using the transmission mode of transmitting the first information in a normal period during the activation time of cell DTX, and during the inactivation time of cell DTX, the base station changes the transmission mode of SIB1 from transmitting the first information in a normal period to transmitting the first information on demand. Assuming that the SSB and CORESET#0 multiplexing mode is 1, and the total cycle duration of cell DTX is 320ms (wherein the activation time of cell DTX is 60ms and the inactivation time of cell DTX is 260ms), as shown in Figure 9, the base station transmits SIB1 only when it receives an uplink wake-up signal that triggers SIB1 transmission sent by the terminal device during the inactivation time of cell DTX (260ms), and during the activation time of cell DTX, the base station transmits SIB1 according to the traditional 20ms SIB1 repetition transmission period.

[0311] Optionally, in the above embodiment, the terminal device is in an RRC inactive state, an RRC idle state or an RRC connected state, and the SIB1 transmission method of this embodiment can enable the terminal device to quickly obtain SIB1 information during the activation time of cell DTX, and can effectively reduce the number of times the base station transmits SIB1 during the inactive time of cell DTX, thereby saving network energy consumption.

[0312] Optionally, if SSB and CORESET#0 multiplexing mode 2 or 3, then within the activation time of cell DTX, the repetition transmission period of SIB1 transmitted by the base station in the above embodiment is adjusted from 20ms to the transmission period of SSB corresponding to SIB1. Specifically, taking the transmission period of SSB as 5ms as an example, in the above embodiment, the base station transmits SIB1 according to the repetition transmission period of SIB1 of 5ms within the activation time of cell DTX.

[0313] Optionally, the transmission timing of the first information may be at least X time slots after the uplink wake-up signal, and the at least X time slots after the uplink wake-up signal overlap with the time slot at which the most recent first information retransmission timing after the uplink wake-up signal is located. Specifically, taking the first information as SIB1 as an example, assuming that the SSB and CORESET#0 multiplexing mode is 1, and the X time slots after the uplink wake-up signal just overlap with the time slot at which the most recent SIB1 retransmission timing is located, the base station transmits SIB1 at the Xth time slot after receiving the uplink wake-up signal, as shown in FIG10 .

[0314] Optionally, in the above embodiment, the duration of X time slots is less than the duration of the repetitive transmission period of SIB1. For example, in the above embodiment, the SSB and CORESET#0 multiplexing mode is 1, and the traditional SIB1 repetitive transmission period is 20ms, then the duration of X time slots is less than 20ms. Specifically, X=20*2^u time slots, where u is the subcarrier spacing of SIB1.

[0315] Optionally, if in the above embodiment, the multiplexing mode of SSB and CORESET#0 is 2 or 3, then X=SSB transmission period*2^u time slots, where u is the subcarrier spacing of SIB1.

[0316] Optionally, the value of u may refer to Table 1.

[0317] Optionally, if it is known that the base station does not send SIB1 during a certain SIB1 repetition transmission period, the terminal device does not need to decode the DCI for SIB1 scheduling corresponding to the repetition period. In the technical solution of this embodiment, the network device triggers the transmission of the first information within a first preset time period based on the received uplink wake-up signal. In a multi-carrier scenario, the number of transmissions of the first information can be effectively reduced, saving network energy consumption and / or reducing operating costs.

[0318] Fourth embodiment

[0319] Based on any of the above embodiments, the fourth embodiment of the present application proposes a transmission method, in which the terminal device sends an uplink wake-up signal to the network device to trigger the network device to send the first information in an on-demand transmission mode.

[0320] Optionally, in response to receiving the uplink wake-up signal, the network device transmits the first information at a transmission timing when the first information meets a first preset rule.

[0321] Optionally, satisfying the first preset rule includes at least one of the following:

[0322] The transmission opportunity is at least X time slots after the time slot in which the uplink wake-up signal is sent, where X is a positive integer;

[0323] The position of not less than X time slots after the uplink wake-up signal overlaps with the time slot of the most recent first information retransmission opportunity after the uplink wake-up signal;

[0324] The transmission opportunity is at least Z time slots after the time slot in which the uplink wake-up signal is sent, where Z is a positive integer;

[0325] The position of not less than Z time slots after the uplink wake-up signal overlaps with the time slot of the Yth time when the first information is repeatedly transmitted closest to the uplink wake-up signal, and both Z and Y are positive integers.

[0326] Optionally, the on-demand transmission mode of the first information may be within a first preset time period and / or a second preset time period.

[0327] Optionally, the first preset time period is an inactive time period for discontinuous transmission of the cell.

[0328] Optionally, the second preset time period is an activation time of discontinuous transmission of the cell.

[0329] Optionally, taking the first information as SIB1 information and the network device as a base station as an example:

[0330] Assuming that the transmission mode of transmitting the first information on demand is within the above-mentioned first preset time period, the base station transmits SIB1 using the transmission mode of transmitting the first information in a normal period during the activation time of cell DTX, and changes the transmission mode of SIB1 from transmitting the first information in a normal period to transmitting the first information on demand during the inactivation time of cell DTX. Assuming that the SSB and CORESET#0 multiplexing mode is 1, and the total cycle duration of cell DTX is 320ms (wherein the activation time of cell DTX is 60ms and the inactivation time of cell DTX is 260ms), as shown in Figure 11, the base station transmits SIB1 only when it receives an uplink wake-up signal triggered by SIB1 transmission sent by the terminal device during the inactivation time of cell DTX (260ms), and during the activation time of cell DTX, the base station transmits SIB1 according to the traditional 20ms SIB1 repetition transmission period.

[0331] Optionally, in the above embodiment, the terminal device is in an RRC inactive state, an RRC idle state or an RRC connected state, and the SIB1 transmission method of this embodiment can enable the terminal device to quickly obtain SIB1 information during the activation time of cell DTX, and can effectively reduce the number of times the base station transmits SIB1 during the inactive time of cell DTX, thereby saving network energy consumption.

[0332] Optionally, if SSB and CORESET#0 multiplexing mode 2 or 3, then within the activation time of cell DTX, the repetition transmission period of SIB1 transmitted by the base station in the above embodiment is adjusted from 20ms to the transmission period of SSB corresponding to SIB1. Specifically, taking the transmission period of SSB as 5ms as an example, the base station in the above embodiment transmits SIB1 according to the repetition transmission period of SIB1 of 5ms within the activation time of cell DTX.

[0333] Optionally, the transmission timing of the first information can be no less than Z time slots after the uplink wake-up signal, and the no less than Z time slots after the uplink wake-up signal overlaps with the time slot where the Yth first information repetition transmission timing is located after the uplink wake-up signal; specifically, taking the first information as SIB1 as an example, assuming that the SSB and CORESET#0 multiplexing mode is 1, the Z time slots after the uplink wake-up signal just overlap with the time slot where the Yth SIB1 repetition transmission timing is located, then the base station performs SIB1 transmission at the Zth time slot after receiving the uplink wake-up signal, as shown in Figure 12.

[0334] Optionally, in the above embodiment, assuming that the SSB and CORESET#0 multiplexing mode is 1, the duration of Z time slots is equal to X + SIB1 repetition transmission period * 2^u * Y. Assuming Y = 2, u = 0, then Z = X + 20ms * 2^u * 2 = X + 40 time slots, as shown in Figure 11.

[0335] Optionally, in the above embodiment, the duration of X time slots is less than the duration of the repetitive transmission period of SIB1. For example, in the above embodiment, the SSB and CORESET#0 multiplexing mode is 1, and the traditional SIB1 repetitive transmission period is 20 ms. Then, the duration of X time slots is less than 20 ms. Specifically, X=20*2^u time slots, where u is the subcarrier spacing of SIB1.

[0336] Optionally, if in the above embodiment, the multiplexing mode of SSB and CORESET#0 is 2 or 3, then X=SSB transmission period*2^u time slots, where u is the subcarrier spacing of SIB1.

[0337] Optionally, the value of u may refer to Table 1.

[0338] Optionally, if it is known that the base station does not send SIB1 in a certain SIB1 repetition transmission period, the terminal device does not need to decode the DCI for SIB1 scheduling corresponding to the repetition period.

[0339] In the technical solution of this embodiment, the network device sends the first information based on the transmission mode determined by the second information, wherein the terminal device sends an uplink wake-up signal to the network device to trigger the network device to send the first information in a transmission mode of transmitting the first information on demand. In a multi-carrier scenario, the number of transmissions of the first information can be effectively reduced, saving network energy consumption and / or reducing operating costs.

[0340] Fifth embodiment

[0341] Based on any of the above embodiments, the fifth embodiment of the present application proposes a transmission method, in which the terminal device sends an uplink wake-up signal to the network device to trigger the network device to send the first information in an on-demand transmission mode.

[0343] Optionally, satisfying the first preset rule includes at least one of the following:

[0344] The transmission opportunity is at least X time slots after the time slot in which the uplink wake-up signal is sent, where X is a positive integer;

[0345] The position of not less than X time slots after the uplink wake-up signal overlaps with the time slot of the most recent first information retransmission opportunity after the uplink wake-up signal;

[0346] The transmission opportunity is at least Z time slots after the time slot in which the uplink wake-up signal is sent, where Z is a positive integer;

[0347] The position of not less than Z time slots after the uplink wake-up signal overlaps with the time slot of the Yth time when the first information is repeatedly transmitted closest to the uplink wake-up signal, and both Z and Y are positive integers.

[0348] Optionally, the on-demand transmission mode of the first information may be within a first preset time period and / or a second preset time period.

[0349] Optionally, the first preset time period is an inactive time period for discontinuous transmission of the cell.

[0350] Optionally, the second preset time period is an activation time of discontinuous transmission of the cell.

[0351] Optionally, taking the first information as SIB1 information as an example, assuming that the transmission mode of transmitting the first information on demand is simultaneously within the first preset time period and the second preset time period, that is, the base station changes the transmission mode of SIB1 from normal periodic transmission of the first information to on-demand transmission of the first information throughout the cell DTX cycle. Assume that the SSB and CORESET#0 multiplexing mode is 1, the total cycle duration of cell DTX is 320ms (wherein the activation time of cell DTX is 60ms and the inactivation time of cell DTX is 260ms), Y=2, then within the 320ms cycle, the base station transmits SIB1 only at the most recent Y=2nd SIB1 repetition transmission cycle opportunity position after receiving the uplink wake-up signal sent by the terminal device, as shown in Figure 13.

[0352] Optionally, in the above embodiments, the terminal device is in an RRC inactive state, an RRC idle state or an RRC connected state.

[0353] Optionally, in the above embodiment, the base station may also transmit SIB1 only at the most recent SIB1 repetition transmission period timing position after receiving the uplink wake-up signal sent by the terminal device within the 320ms period, that is, the schematic diagram of the uplink wake-up signal and SIB1 transmission timing is shown in Figure 10.

[0354] Optionally, if it is known that the base station does not send SIB1 in a certain SIB1 repetition transmission period, the terminal device does not need to decode the DCI for SIB1 scheduling corresponding to the repetition period.

[0355] Compared with the third or fourth embodiment, the technical solution of this embodiment can further reduce the number of SIB1 transmissions by extending the on-demand transmission mode of the first information to the entire cell DTX period, thereby further reducing network energy consumption.

[0356] Sixth embodiment

[0357] Based on any of the above embodiments, the sixth embodiment of the present application proposes a transmission method, in which the network device instructs the terminal device through downlink control information and / or wireless resource control message to send the first information in a transmission mode without transmitting the first information.

[0358] Optionally, the network device sends downlink control information and / or wireless resource control message to the terminal device to indicate whether the network device transmits the first information at the corresponding first information transmission opportunity within the first preset time period and / or the second preset time period.

[0359] Optionally, the first preset time period is an inactive time period for discontinuous transmission of the cell.

[0360] Optionally, the second preset time period is an activation time of discontinuous transmission of the cell.

[0361] Optionally, taking the first information as SIB1 information and the network device as a base station as an example:

[0362] Assuming that the transmission mode without first information transmission is only within the above-mentioned second preset time period, then during the activation time of cell DTX, the base station changes the transmission mode of SIB1 from normal periodic transmission of first information to a transmission mode without first information transmission, and during the inactivation time of cell DTX, the base station does not transmit SIB1 at any SIB1 repetition transmission period. Assuming that the SSB and CORESET#0 multiplexing mode is 1, and the total cycle duration of cell DTX is 640ms (wherein the activation time of cell DTX is 100ms and the inactivation time of cell DTX is 540ms), as shown in Figure 14, the base station instructs the network device whether to transmit SIB1 in the current SIB1 repetition transmission period by sending a public DCI (e.g., DCI format 1_0) to the terminal device during the activation time of cell DTX (100ms).

[0363] Optionally, assuming that the public DCI is DCI format 1_0, the activation or deactivation indication field of the first information is used to indicate whether the base station transmits the first information during a first information repetition period. Specifically, a 1-bit activation or deactivation indication field of the first information can be added to DCI format 1_0, where a bit of 0 indicates that SIB1 does not need to be transmitted during the current SIB1 repetition transmission period, and a bit of 1 indicates that SIB1 needs to be transmitted during the current SIB1 repetition transmission period.

[0364] Optionally, in the above embodiments, the terminal device is in an RRC inactive state, an RRC idle state or an RRC connected state.

[0365] Optionally, if the above embodiment is in an RRC connected state, the downlink control information (common DCI) in the above embodiment can be replaced by an RRC message.

[0366] Optionally, if the multiplexing mode of SSB and CORESET#0 is 1, the repetition transmission period of SIB1 is 20ms; if the multiplexing mode of SSB and CORESET#0 is 2 or 3, the repetition transmission period of SIB1 is the same as the transmission period of SSB corresponding to SIB1. Specifically, taking the transmission period of SSB as 40ms as an example, the repetition transmission period of SIB1 is 40ms.

[0367] Optionally, the transmission mode without first information transmission may also be only within the first preset time period, and within the second preset time period, the base station sends SIB1 using the transmission mode of transmitting the first information in a normal period.

[0368] Optionally, the transmission mode without first information transmission may also be within the first preset time period and the second preset time period at the same time.

[0369] Optionally, the public DCI (such as DCI format 1_0) may further include at least one of the following:

[0370] Frequency domain resource allocation field, the number of bits it accounts for is in is the size of CORESET#0;

[0371] Time domain resource allocation field, the number of bits is 4;

[0372] Virtual resource block to physical resource block mapping field, the number of bits occupied is 1;

[0373] Modulation and coding scheme field, the number of bits is 5;

[0374] Redundant version field, the number of bits it accounts for is 2;

[0375] System information indication field, the percentage is 1.

[0376] Optionally, if it is known that the base station does not send SIB1 in a certain SIB1 repetition transmission period, the terminal device does not need to decode the DCI for SIB1 scheduling corresponding to the repetition period.

[0377] In the technical solution of this embodiment, the network device sends the first information based on the transmission method determined by the second information, wherein the network device instructs the terminal through downlink control information and / or wireless resource control message that the network device sends the first information in a transmission method without transmitting the first information, which can effectively reduce the number of transmissions of the first information, save network energy consumption and / or reduce operating costs.

[0378] Seventh embodiment

[0379] Based on any of the above embodiments, the seventh embodiment of the present application proposes a transmission method, in which the network device instructs the terminal device through downlink control information and / or wireless resource control message to send the first information in a transmission mode without transmitting the first information.

[0380] Optionally, the network device sends downlink control information and / or wireless resource control message to the terminal device to indicate whether the network device transmits the first information at the corresponding first information transmission opportunity within the first preset time period.

[0381] Optionally, the first preset time period is an inactive time period for discontinuous transmission of the cell.

[0382] Optionally, taking the first information as SIB1 information and the network device as a base station as an example:

[0383] Assuming that the transmission mode without first information transmission is only within the above-mentioned second preset time period, then during the activation time of cell DTX, the base station changes the transmission mode of SIB1 from normal periodic transmission of first information to a transmission mode without first information transmission. During the inactivation time of cell DTX, the base station does not transmit SIB1 during all SIB1 repetition transmission period opportunities. Assuming that the SSB and CORESET#0 multiplexing mode is 1, and the total cycle duration of cell DTX is 640ms (wherein the activation time of cell DTX is 100ms and the inactivation time of cell DTX is 540ms), as shown in Figure 15, the base station sends a common DCI (e.g., DCI format 1_0) to the terminal during the activation time of cell DTX (100ms) to instruct the network device whether to transmit SIB1 during the current or future N SIB1 repetition transmission periods.

[0384] Optionally, let the common DCI be DCI format1_0, and the activation or deactivation indication field of the first information is used to indicate whether the base station transmits the first information at multiple first information repetition period opportunities. Specifically, an 8-bit activation or deactivation indication field of the first information can be added to DCI format 1_0, wherein each bit corresponds to whether SIB1 needs to be transmitted at each repetition period opportunity in the 160ms transmission period of SIB1. Specifically, the 8 bits, from the highest bit to the lowest bit, respectively indicate whether SIB1 needs to be transmitted at the first repetition period opportunity in the 160ms transmission period, whether SIB1 needs to be transmitted at the second repetition period opportunity, ..., whether SIB1 needs to be transmitted at the eighth repetition period opportunity. For example, bits 0000 0000 indicate that during the cell DTX activation time, SIB1 does not need to be transmitted in any of the eight SIB1 repetition transmission periods within the SIB1 transmission period. Bits 1010 0101 indicate that during the cell DTX activation time, SIB1 transmission is performed in the first, third, sixth, and eighth SIB1 repetition transmission periods within the SIB1 transmission period, while SIB1 transmission does not need to be performed in the second, fourth, fifth, and seventh repetition periods within the SIB1 transmission period.

[0385] Optionally, if the activation time of cell DTX only includes part of the SIB1 repetition transmission period within the SIB1 transmission period, it is only necessary to extract the indication bits corresponding to the SIB1 repetition transmission period falling within the cell DTX activation time in DCI format 1_0. For example, in the schematic diagram of Figure 15, it is only necessary to extract bits 2-5 of the SIB1 repetition transmission period transmission indication in DCI format 1_0.

[0386] Optionally, in the above embodiments, the terminal device is in an RRC inactive state, an RRC idle state or an RRC connected state.

[0387] Optionally, if the above embodiment is in an RRC connected state, the downlink control information (common DCI) in the above embodiment can be replaced by an RRC message.

[0388] Optionally, if the SSB and CORESET#0 multiplexing mode is 1, the repetition transmission period of SIB1 is 20ms; if the SSB and CORESET#0 multiplexing mode is 2 or 3, the repetition transmission period of SIB1 is the same as the transmission period of the SSB corresponding to SIB1. Specifically, taking the transmission period of SSB as 5ms as an example, the repetition transmission period of SIB1 is 5ms.

[0389] Optionally, the transmission mode without first information transmission may also be only within the first preset time period, and within the second preset time period, the base station sends SIB1 using the transmission mode of transmitting the first information in a normal period.

[0390] Optionally, the transmission mode without first information transmission may also be within the first preset time period and the second preset time period at the same time.

[0391] Optionally, if it is known that the base station does not send SIB1 in a certain SIB1 repetition transmission period, the terminal device does not need to decode the DCI for SIB1 scheduling corresponding to the repetition period.

[0392] In the technical solution of this embodiment, the network device sends the first information based on the transmission mode determined by the second information, wherein the network device instructs the terminal device to send the first information in a transmission mode without transmitting the first information through downlink control information and / or wireless resource control message. In a multi-carrier scenario, the number of transmissions of the first information can be effectively reduced, saving network energy consumption and / or reducing operating costs.

[0393] Eighth embodiment

[0394] Based on any of the above embodiments, the eighth embodiment of the present application proposes a transmission method, in which the network device instructs the terminal through downlink control information and / or wireless resource control message to send the first information in a transmission mode of dynamically adjusting the period of transmission of the first information.

[0395] Optionally, the network device sends downlink control information and / or wireless resource control message to the terminal device to indicate whether the network device transmits the first information using a transmission method of dynamically adjusting the period to transmit the first information within the first preset time period and / or the second preset time period.

[0396] Optionally, the first preset time period is an inactive time period for discontinuous transmission of the cell.

[0397] Optionally, the second preset time period is an activation time of discontinuous transmission of the cell.

[0398] Optionally, the network device may indicate the dynamically adjusted transmission period of the first information through a first information transmission period dynamic adjustment field in the downlink control information.

[0399] Optionally, the number of bits of the first information transmission period dynamic adjustment field is related to the multiplexing mode of the synchronization signal block and the control resource set #0.

[0400] Optionally, assume that the SSB and CORESET#0 multiplexing mode is 1, the number of bits indicating the dynamic adjustment of the first information transmission period in the downlink control information is 2, and each code point corresponds to a value in the set L = {0, 1, 2}. For example, bit '00' indicates that the repetition transmission period of SIB1 is adjusted to 20ms*2^0=20ms, that is, the repetition transmission period of SIB1 is not adjusted; bit '01' indicates that the repetition transmission period of SIB1 is adjusted to 20ms*2^1=40ms; bit '10' indicates that the repetition transmission period of SIB1 is adjusted to 20ms*2^2=80ms, and so on.

[0401] Optionally, assume that the SSB and CORESET#0 multiplexing mode is 2 or 3, the number of bits indicating the dynamic adjustment of the first information transmission period in the downlink control information is 4, and each code point corresponds to the set L = {-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5}. For example, bit '0000' corresponds to the value -5, indicating that the repetition transmission period of SIB1 is adjusted to SSB period * 2^(-5); bit '0001' corresponds to the value -4, indicating that the repetition transmission period of SIB1 is adjusted to SSB period * 2^(-4), and so on.

[0402] Optionally, for SSB and CORESET#0 multiplexing mode 2 or 3, the repetition transmission period of SIB1 calculated by the formula SSB period*2^L1 is not less than 5ms and not more than 160ms; where L1 is any value in the set L.

[0403] Optionally, taking the first information as SIB1 information and the network device as a base station as an example:

[0404] Assuming that the transmission mode of dynamically adjusting the periodic transmission of the first information is within both the first preset time period and the second preset time period, the base station changes the transmission mode of SIB1 from normal periodic transmission of the first information to dynamic periodic transmission of the first information during the activation time and the inactivation time of cell DTX. Assuming that the SSB and CORESET#0 multiplexing mode is 1, the total duration of the cell DTX cycle is 640ms (wherein the activation time of cell DTX is 100ms and the inactivation time of cell DTX is 540ms). If, during the cell DTX activation time, the first information transmission period dynamic adjustment indication bit in DCI format 1_0 is '01', the base station will transmit SIB1 according to a repetition period of 20ms*2^1=40ms during the cell DTX activation time, that is, only 4 SIB1 transmissions will be performed within the 160ms period of SIB1. If the first information transmission period dynamic adjustment indication bit in DCI format 1_0 is '10' during the cell DTX inactive time, the base station will transmit SIB1 according to a repetition period of 20ms*2^2=80ms during the cell DTX active time, that is, only two SIB1 transmissions will be performed within the 160ms period of SIB1, as shown in Figure 16.

[0405] Optionally, in the above embodiments, the terminal device is in an RRC inactive state, an RRC idle state or an RRC connected state.

[0406] Optionally, if the above embodiment is in an RRC connected state, the downlink control information in the above embodiment may be replaced by an RRC message.

[0407] Optionally, the transmission mode of dynamically adjusting the periodic transmission of the first information may be only within the second preset time period, while within the first preset time period, the base station does not perform SIB1 at all SIB1 repetition transmission period opportunities.

[0408] Optionally, the transmission mode of dynamically adjusting the periodic transmission of the first information may be only within the first preset time period, while within the second preset time period, the base station adopts the transmission mode of transmitting the first information in a normal periodic transmission to perform SIB1 transmission.

[0409] In the technical solution of this embodiment, the network device sends the first information based on the transmission method determined by the second information, wherein the network device instructs the terminal through downlink control information and / or wireless resource control message that the network device sends the first information in a transmission method of dynamically adjusting the transmission period of the first information.

[0446] Optionally, the activation or deactivation indication field of the first information is used to indicate whether the base station transmits the first information at one or more first information repetition period opportunities.

[0447] Optionally, the activation or deactivation indication field of the first information is used to indicate whether the base station transmits the first information at one or more first information repetition period opportunities.

[0448] Optionally, the method further comprises at least one of the following:

[0449] During the second preset time period, the transmission mode is to transmit the first information in a normal period;

[0450] During the second preset time period, the transmission mode is no first information transmission;

[0451] During the first preset time period and / or the second preset time period, the transmission mode is to transmit the first information on demand;

[0452] During the first preset time period and / or the second preset time period, the transmission mode is to dynamically adjust the period to transmit the first information;

[0453] During the first preset time period, the first information is not received.

[0454] Optionally, taking the first information as SIB1 information, the terminal device as UE, and the network device as a base station as an example, the above transmission modes are as follows:

[0455] Optionally, for on-demand transmission of the first information:

[0456] In one implementation, if the UE is in the RRC Inactive state or the RRC Idle state:

[0457] Then, during the second preset time period, the base station adopts a normal periodic transmission method of transmitting the first information to transmit SIB1 information; and during the first preset time period, the base station adopts an on-demand transmission method of transmitting the first information to transmit SIB1 information. Specifically, during the cell DTX inactive time, the base station transmits SIB1 information only after receiving an uplink wake-up signal and at a transmission timing that meets the first preset rule; and during the cell DTX active time, the base station transmits SIB1 information according to the traditional SIB1 repeated transmission period.

[0458] Optionally, the traditional SIB1 period is 160ms.

[0459] Optionally, for SSB and CORESET#0 multiplexing mode 1, the traditional SIB1 repetition transmission period is 20ms within 160ms.

[0460] Optionally, for SSB and CORESET#0 multiplexing mode 2 or 3, within 160ms, the traditional SIB1 repetition transmission period is the same as the period of the SSB associated with SIB1.

[0461] If the UE is in the RRC Connected state:

[0462] Then, during the second preset time period, the base station adopts a normal periodic transmission method of transmitting the first information to transmit SIB1 information; and during the first preset time period, the base station adopts an on-demand transmission method of transmitting the first information to transmit SIB1 information. Specifically, during the cell DTX inactive time, the base station transmits SIB1 information only after receiving an uplink wake-up signal and at a transmission timing that meets the first preset rule; and during the cell DTX active time, the base station transmits SIB1 information according to the traditional SIB1 repeated transmission period.

[0463] Optionally, if SIB1 transmission is not performed in a certain SIB1 repetition transmission period, the DCI scheduling this SIB1 does not need to be sent to the terminal. Specifically, if SIB1 transmission is required in a certain SIB1 repetition transmission period, the base station needs to send the DCI scheduling this SIB1 to the terminal before the SIB1 transmission; if SIB1 transmission is not performed in a certain SIB1 repetition transmission period, the base station does not need to send the DCI corresponding to this SIB1 to the terminal.

[0464] In another implementation, if the UE is in the RRC Inactive state or the RRC Idle state:

[0465] Then, within the first preset time period and the second preset time period, the base station adopts the transmission method of transmitting the first information on demand to transmit SIB1 information. Specifically, during the cell DTX activation time and the non-activation time, the base station transmits SIB1 information only after receiving the uplink wake-up signal and at the transmission timing that meets the first preset rule.

[0466] Similarly, if the UE is in the RRC Connected state:

[0467] Then, within the first preset time period and the second preset time period, the base station adopts the transmission method of transmitting the first information on demand to transmit SIB1 information. Specifically, during the cell DTX activation time and the non-activation time, the base station transmits SIB1 information only after receiving the uplink wake-up signal and at the transmission timing that meets the first preset rule.

[0468] Optionally, in the above two implementations, for each RRC state, the above behavior restrictions can be arbitrarily combined.

[0469] Optionally, when there is no first information transmission (such as no SIB1 transmission):

[0470] If the UE is in the RRC Inactive state or the RRC Idle state:

[0471] Then, during the second preset time period, the base station adopts a transmission method without first information transmission to transmit SIB1 information; and during the first preset time period, the base station does not perform SIB1 transmission in all SIB1 repetition period opportunities. Specifically, during the cell DTX activation time, the base station instructs the network device whether to perform SIB1 transmission in the corresponding SIB1 repetition period by sending a DCI format 1_0 containing an activation or deactivation indication field of the newly added first information to the terminal. Assume that the number of activation or deactivation indication fields for the first information in DCI format 1_0 is 1, and a bit of 1 represents that there is SIB1 transmission in the current SIB1 repetition period opportunity, and a bit of 0 represents that there is no SIB1 transmission in the current SIB1 repetition period opportunity; during the cell DTX inactive time, the base station does not perform SIB1 transmission in all SIB1 repetition period opportunities.

[0472] If the UE is in the RRC Connected state:

[0473] Then, during the second preset time period, the base station transmits SIB1 information in a transmission mode without first information transmission; and during the first preset time period, the base station does not transmit SIB1 in all SIB1 repeated transmission period opportunities.

[0474] Optionally, if the UE is in the RRC Inactive state, the RRC Idle state or the RRC Connected state, the base station may also adopt a transmission mode without first information transmission to transmit SIB1 information in both the first preset time period and the second preset time period.

[0475] Optionally, for dynamically adjusting the periodic transmission SIB1:

[0476] In one implementation, if the UE is in the RRC Inactive state or the RRC Idle state:

[0477] In both the first preset time period and the second preset time period, the base station transmits SIB1 information using a transmission method of dynamically adjusting the period for transmitting the first information. Specifically, during the cell DTX activation time and the cell DTX inactivation time, the base station transmits a DCI format 1_0 including bits of a newly added first information transmission period dynamic adjustment field to the terminal, thereby instructing the network device to repeat the transmission period in subsequent SIB1 transmissions.

[0478] Optionally, the number of bits of the first information transmission period dynamic adjustment field in DCI format 1_0 is related to the multiplexing mode of SSB and CORESET#0.

[0479] Optionally, for SSB and CORESET#0 multiplexing mode 1, the number of bits of the first information transmission period dynamic adjustment field in DCI format 1_0 can be 2, and each code point corresponds to a value in the set L={0,1,2}, for example, bit '00 corresponds to the value 0 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H=20ms*2^0; '01 corresponds to the value 1 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H=20ms*2^1; '10' corresponds to the value 2 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H=20ms*2^2, and so on.

[0480] Optionally, for SSB and CORESET#0 multiplexing mode 2 or 3, the number of bits of the first information transmission period dynamic adjustment field in DCI format 1_0 can be 4, and each code point corresponds to a value in the set L = {-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5}, for example, bit '00 corresponds to the value -5 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H = SSB period * 2^(-5); '01 corresponds to the value -4 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H = SSB period * 2^(-4), and so on.

[0481] Optionally, for SSB and CORESET#0 multiplexing mode 2 or 3, the adjusted repetition transmission period H of SIB1 is not less than 5ms and not more than 160ms. If the value after SSB period * 2^L1 is less than 5ms, the adjusted repetition transmission period of SIB1 is 5ms. Similarly, if the value after SSB period * 2^L1 is greater than 160ms, the adjusted repetition transmission period of SIB1 is 160ms, where L1 is any value in the set L.

[0482] If the UE is in the RRC Connected state:

[0483] In the first preset time period and the second preset time period, the base station transmits the SIB1 information using a transmission method of dynamically adjusting the period for transmitting the first information. Specifically, during the cell DTX activation time and the cell DTX inactivation time, the base station dynamically indicates the adjusted SIB1 repetition transmission period to the UE through an RRC message or DCI format 1_0.

[0484] Optionally, the RRC message may directly indicate the adjusted repetition transmission period of SIB1, for example, the RRC message directly indicates that the repetition transmission period of SIB1 is 5ms, 160ms, etc.

[0485] Optionally, the RRC message may also indicate that the adjusted retransmission period of SIB1 is a multiple of the current SIB1 retransmission period. For example, the retransmission period of SIB1 configured in the RRC message is adjusted to M times or 2^N times the current SIB1 retransmission period, where M and N are positive integers.

[0486] Optionally, the repetition transmission period of SIB1 in the downlink control information may also be adjusted to M times or 2^N times the repetition transmission period of the current SIB1.

[0487] The following takes the example of adjusting the repetition transmission period of SIB1 in the downlink control information to 2^N times the repetition transmission period of the current SIB1 as an example.

[0488] Optionally, the number of bits of the first information transmission period dynamic adjustment field in DCI format 1_0 is related to the multiplexing mode of SSB and CORESET#0.

[0489] Optionally, for SSB and CORESET#0 multiplexing mode 1, the number of bits of the first information transmission period dynamic adjustment field in DCI format 1_0 can be 2, and each code point corresponds to a value in the set L={0,1,2}, for example, bit '00 corresponds to the value 0 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H=20ms*2^0; '01 corresponds to the value 1 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H=20ms*2^1; '10' corresponds to the value 2 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H=20ms*2^2, and so on.

[0490] Optionally, for SSB and CORESET#0 multiplexing mode 2 or 3, the number of bits of the first information transmission period dynamic adjustment field in DCI format 1_0 can be 4, and each code point corresponds to a value in the set L = {-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5}, for example, bit '00 corresponds to the value -5 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H = SSB period * 2^(-5); '01 corresponds to the value -4 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H = SSB period * 2^(-4), and so on.

[0491] Optionally, for SSB and CORESET#0 multiplexing mode 2 or 3, the traditional SIB1 repetition transmission period H is not less than 5ms and not more than 160ms. If the value after SSB period * 2^L1 is less than 5ms, the repetition transmission period of SIB1 is 5ms. Similarly, if the value after SSB period * 2^L1 is greater than 160ms, the repetition transmission period of SIB1 is 160ms, where L1 is any value in the set L.

[0492] In another implementation, if the UE is in the RRC Inactive state, RRC Idle state, or RRC Connected state:

[0493] During the second preset time period, the base station transmits SIB1 information using a transmission method of dynamically adjusting the periodic transmission of the first information; during the first preset time period, the base station does not transmit SIB1 during all SIB1 repeated transmission periodic opportunities.

[0494] Optionally, the above RRC states and first information transmission modes may be combined arbitrarily.

[0495] Optionally, the DCI format 1_0 further includes at least one of the following:

During the cell DTX active time, the base station transmits SIB1 information according to the traditional SIB1 repetitive transmission period.

[0569] Optionally, if SIB1 transmission is not performed in a certain SIB1 repetition transmission period, the DCI scheduling this SIB1 does not need to be sent to the terminal. Specifically, if SIB1 transmission is required in a certain SIB1 repetition transmission period, the base station needs to send the DCI scheduling this SIB1 to the terminal before the SIB1 transmission; if SIB1 transmission is not performed in a certain SIB1 repetition transmission period, the base station does not need to send the DCI corresponding to this SIB1 to the terminal.

[0570] In another implementation, if the UE is in the RRC Inactive state or the RRC Idle state:

[0571] Then, within the first preset time period and the second preset time period, the base station adopts the transmission method of transmitting the first information on demand to transmit SIB1 information. Specifically, during the cell DTX activation time and the non-activation time, the base station transmits SIB1 information only after receiving the uplink wake-up signal and at the transmission timing that meets the first preset rule.

[0572] Similarly, if the UE is in the RRC Connected state:

[0573] Then, within the first preset time period and the second preset time period, the base station adopts the transmission method of transmitting the first information on demand to transmit SIB1 information. Specifically, during the cell DTX activation time and the non-activation time, the base station transmits SIB1 information only after receiving the uplink wake-up signal and at the transmission timing that meets the first preset rule.

[0574] Optionally, in the above two implementations, for each RRC state, the above behavior restrictions can be arbitrarily combined.

[0575] Optionally, when there is no first information transmission (such as no SIB1 transmission):

[0576] If the UE is in the RRC Inactive state or the RRC Idle state:

[0577] Then, during the second preset time period, the base station adopts a transmission method without first information transmission to transmit SIB1 information; and during the first preset time period, the base station does not perform SIB1 transmission in all SIB1 repetition period opportunities. Specifically, during the cell DTX activation time, the base station instructs the network device whether to perform SIB1 transmission in the corresponding SIB1 repetition period by sending a DCI format 1_0 containing an activation or deactivation indication field of the newly added first information to the terminal. Assume that the number of activation or deactivation indication fields for the first information in DCI format 1_0 is 1, and a bit of 1 represents that there is SIB1 transmission in the current SIB1 repetition period opportunity, and a bit of 0 represents that there is no SIB1 transmission in the current SIB1 repetition period opportunity; during the cell DTX inactive time, the base station does not perform SIB1 transmission in all SIB1 repetition period opportunities.

[0578] If the UE is in the RRC Connected state:

[0579] Then, during the second preset time period, the base station transmits SIB1 information in a transmission mode without first information transmission; and during the first preset time period, the base station does not transmit SIB1 in all SIB1 repeated transmission period opportunities.

[0580] Optionally, if the UE is in the RRC Inactive state, the RRC Idle state or the RRC Connected state, the base station may also adopt a transmission mode without first information transmission to transmit SIB1 information in both the first preset time period and the second preset time period.

[0581] Optionally, for dynamically adjusting the periodic transmission SIB1:

[0582] In one implementation, if the UE is in the RRC Inactive state or the RRC Idle state:

[0583] In both the first preset time period and the second preset time period, the base station transmits SIB1 information using a transmission method of dynamically adjusting the period for transmitting the first information. Specifically, during the cell DTX activation time and the cell DTX inactivation time, the base station transmits a DCI format 1_0 including bits of a newly added first information transmission period dynamic adjustment field to the terminal, thereby instructing the network device to repeat the transmission period in subsequent SIB1 transmissions.

[0584] Optionally, the number of bits of the first information transmission period dynamic adjustment field in DCI format 1_0 is related to the multiplexing mode of SSB and CORESET#0.

[0585] Optionally, for SSB and CORESET#0 multiplexing mode 1, the number of bits of the first information transmission period dynamic adjustment field in DCI format 1_0 can be 2, and each code point corresponds to a value in the set L={0,1,2}, for example, bit '00 corresponds to the value 0 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H=20ms*2^0; '01 corresponds to the value 1 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H=20ms*2^1; '10' corresponds to the value 2 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H=20ms*2^2, and so on.

[0586] Optionally, for SSB and CORESET#0 multiplexing mode 2 or 3, the number of bits of the first information transmission period dynamic adjustment field in DCI format 1_0 can be 4, and each code point corresponds to a value in the set L = {-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5}, for example, bit '00 corresponds to the value -5 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H = SSB period * 2^(-5); '01 corresponds to the value -4 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H = SSB period * 2^(-4), and so on.

[0587] Optionally, for SSB and CORESET#0 multiplexing mode 2 or 3, the adjusted repetition transmission period H of SIB1 is not less than 5ms and not more than 160ms. If the value after SSB period * 2^L1 is less than 5ms, the repetition transmission period of SIB1 is 5ms. Similarly, if the value after SSB period * 2^L1 is greater than 160ms, the repetition transmission period of SIB1 is 160ms, where L1 is any value in the set L.

[0588] If the UE is in the RRC Connected state:

[0589] In the first preset time period and the second preset time period, the base station transmits the SIB1 information using a transmission method of dynamically adjusting the period for transmitting the first information. Specifically, during the cell DTX activation time and the cell DTX inactivation time, the base station dynamically indicates the adjusted SIB1 repetition transmission period to the UE through an RRC message or DCI format 1_0.

[0590] Optionally, the RRC message may directly indicate the adjusted repetition transmission period of SIB1, for example, the RRC message directly indicates that the repetition transmission period of SIB1 is 5ms, 160ms, etc.

[0591] Optionally, the RRC message may also indicate that the adjusted retransmission period of SIB1 is a multiple of the current SIB1 retransmission period. For example, the retransmission period of SIB1 configured in the RRC message is adjusted to M times or 2^N times the current SIB1 retransmission period, where M and N are positive integers.

[0592] Optionally, the repetition transmission period of SIB1 in the downlink control information may also be adjusted to M times or 2^N times the repetition transmission period of the current SIB1.

[0593] The following takes the example of adjusting the repetition transmission period of SIB1 in the downlink control information to 2^N times the repetition transmission period of the current SIB1 as an example.

[0594] Optionally, the number of bits of the first information transmission period dynamic adjustment field in DCI format 1_0 is related to the multiplexing mode of SSB and CORESET#0.

[0595] Optionally, for SSB and CORESET#0 multiplexing mode 1, the number of bits of the first information transmission period dynamic adjustment field in DCI format 1_0 can be 2, and each code point corresponds to a value in the set L={0,1,2}, for example, bit '00 corresponds to the value 0 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H=20ms*2^0; '01 corresponds to the value 1 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H=20ms*2^1; '10' corresponds to the value 2 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H=20ms*2^2, and so on.

[0596] Optionally, for SSB and CORESET#0 multiplexing mode 2 or 3, the number of bits of the first information transmission period dynamic adjustment field in DCI format 1_0 can be 4, and each code point corresponds to a value in the set L = {-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5}, for example, bit '00 corresponds to the value -5 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H = SSB period * 2^(-5); '01 corresponds to the value -4 in the set, that is, the corresponding repetition transmission period of SIB1 is adjusted to H = SSB period * 2^(-4), and so on.

[0597] Optionally, for SSB and CORESET#0 multiplexing mode 2 or 3, the traditional SIB1 repetition transmission period H is not less than 5ms and not more than 160ms. If the value after SSB period * 2^L1 is less than 5ms, the repetition transmission period of SIB1 is 5ms. Similarly, if the value after SSB period * 2^L1 is greater than 160ms, the repetition transmission period of SIB1 is 160ms, where L1 is any value in the set L.

[0598] In another implementation, if the UE is in the RRC Inactive state, RRC Idle state, or RRC Connected state:

[0599] During the second preset time period, the base station transmits SIB1 information using a transmission method of dynamically adjusting the periodic transmission of the first information; during the first preset time period, the base station does not transmit SIB1 during all SIB1 repeated transmission periodic opportunities.

[0600] Optionally, the above RRC states and first information transmission modes may be combined arbitrarily.

[0601] Optionally, the DCI format 10 further includes at least one of the following:

[0602] Frequency domain resource allocation field, the number of bits it accounts for is in is the size of CORESET#0;

[0603] Time domain resource allocation field, the number of bits is 4;

[0604] Virtual resource block to physical resource block mapping field, the number of bits occupied is 1;

[0605] Modulation and coding scheme field, the number of bits is 5;

[0606] Redundant version field, the number of bits it accounts for is 2;

[0607] System information indication field, the percentage is 1.

[0608] Optionally, if it is known that the base station does not send SIB1 in a certain SIB1 repetition transmission period, the terminal device does not need to decode the DCI for SIB1 scheduling corresponding to the repetition period.

[0609] In the technical solution of this embodiment, the network device sends the first information based on the transmission method determined by the second information, and the terminal device receives the first information. In a multi-carrier scenario, the number of transmissions of SIB1 can be reduced, thereby reducing energy consumption and / or reducing operating costs.
