[0084] 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."

[0088] 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.

[0089] 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.

[0090] In this application, a communication device may be a terminal device or a network device (such as a base station), and the specific definition needs to be determined based on the context. In addition, the terminal device can be implemented in various forms. For example, the terminal devices described in this application may include mobile terminals such as mobile phones, tablet computers, laptop computers, PDAs, portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc., as well as fixed terminals such as digital TVs and desktop computers.

[0091] The subsequent description will take a mobile terminal as an example of a terminal device. Those skilled in the art will understand 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.

[0092] 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.

[0093] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:

[0094] The RF unit 101 can be used to send and receive information or receive signals during 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 more. 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-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution), TDD-LTE (Time Division Duplexing-Long Term Evolution) and 5G, etc.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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 in detail here.

[0099] 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.

[0100] 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.

[0101] 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.

[0103] 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.

[0104] 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.

[0105] The mobile terminal 100 may also include a power supply 111 (such as a battery) for supplying power to various components. Preferably, the power supply 111 may be logically connected to the processor 110 through a power management system, thereby managing functions such as charging, discharging, and energy consumption management through the power management system.

[0122] The physical uplink control channel (PUCCH) mainly carries information such as ACK (Acknowledgement) / NACK (Negative Acknowledgement), scheduling request (SR), and channel state information (CSI).

[0123] The Physical Uplink Shared Channel (PUSCH) is used to carry uplink service information or uplink signaling data from terminal devices. Sharing means that the same physical channel can be used by multiple users in a time-sharing manner, or the channel has a short duration.

[0124] Field: A field in downlink control information or Radio Resource Control (RRC) parameters.

[0125] The Transmission Configuration Indication state (TCI state) is used to provide Quasi Co-Location (QCL) information for downlink channel or reference signal reception and / or provide uplink spatial filter information for uplink channel or reference signal transmission.

[0126] The Transmission Configuration Indication field (TCI field) is used to indicate the transmission configuration indication status.

[0127] Downlink control information (DCI) is information content carried by PDCCH, which can be sent by network equipment to terminal equipment through PDCCH channel and can carry TCI field.

[0128] In addition, network devices can also receive feedback from terminal devices. To ensure effective and normal communication between terminal devices and network devices, the network devices and terminal devices need to use the same configuration information, which is mainly sent by the network device to the terminal through Radio Resource Control (RRC) parameters or Downlink Control Information (DCI).

[0129] In the LTE scenario, due to the small number of terminal devices, the energy consumption of network equipment is within a controllable range. However, with the popularization of 5G, the number of terminal devices and network demand increase, the energy consumption of network equipment is getting higher and higher, which is not conducive to the sustainable operation of the network.

[0130] In order to solve the above technical problems, the solution provided in the embodiment of the present application considers extending the period of the public signal sent by the network device. For cells with less communication demand, the sending function of the network device can even be canceled or the sending function of some beams can be terminated to reduce the signal sending amount of the network device and solve the technical problem of high energy consumption of the network device.

[0131] FIG3 is a diagram illustrating an example application scenario of a processing method according to an embodiment. As shown in FIG3 , a network device TRP 301 (Transmission / Reception Point) may correspond to a target cell 302, which may include a mobile terminal device 303. Network device 301 may send downlink information to terminal device 303. Terminal device 303 may send uplink information to network device 301.

[0132] Figure 4 is a flow chart of a processing method according to the first embodiment of the present application. The processing method provided in the present application can be applied to a network device (such as a base station) that can be accessed by a terminal device.

[0133] As shown in FIG4 , the processing method provided in this application may include the following steps:

[0134] S1: In response to satisfying a first preset condition, sending first downlink information and entering a power-saving state.

[0135] The energy-saving state may mean that the network device turns off the transmission and reception of business data, and can perform necessary synchronization signal block transmission, and the transmission period of the synchronization signal block is greater than the transmission period of the synchronization signal block in the normal state.

[0136] Optionally, the energy-saving state may include at least one of deep sleep, light sleep, and micro sleep. Deep sleep, light sleep, or micro sleep may be a sleep mode of the device. In any one or more of deep sleep, light sleep, and micro sleep modes, the device may enter a low-power state, i.e., an energy-saving state.

[0137] Optionally, the order of sending the first downlink information in step S1 can be limited to sending the first downlink information before entering the energy-saving state or after entering the energy-saving state. The order of steps shown in Figure 3 is merely exemplary and does not constitute a specific limitation on the order of sending the first downlink information and entering the energy-saving state.

[0138] In this embodiment, the network device may transmit the first downlink information and enter an energy-saving state if a first preset condition is met. The network device in the energy-saving state may transmit necessary synchronization signal blocks and / or receive uplink wake-up signals at a specified time to reduce energy consumption of the network device. Furthermore, by transmitting the first downlink information to the terminal device, the terminal device is instructed to enter the energy-saving state through the first downlink information, thereby achieving communication synchronization between the terminal device and the network device, improving the energy-saving efficiency of the device, and preventing the terminal device from transmitting invalid information to the network device.

[0139] In this embodiment, in addition to entering the energy-saving state in response to satisfying the first preset condition, the network device can also restore to the normal state when satisfying the second preset condition. That is, the network device can quickly switch between the energy-saving state and the effective state through the first preset condition and the second preset condition.

[0140] Optionally, the first preset condition may include at least one of the following:

[0141] The first type: the number of residences in all beam directions of the synchronization signal block burst set of the target cell is less than the first target threshold.

[0142] Optionally, the number of resident devices in all beam directions in the synchronization signal block burst set in the target cell is less than the first target threshold, which may include the number of terminal devices that interact with the network device for data on all beams with the synchronization signal block burst set position parameter set to 1 being less than the first target threshold. The value of the first target threshold can be set according to actual usage requirements. For example, the value of the first target threshold can be associated with the time period in which the current terminal device is working, such as whether the terminal device is working during the day or at night. If it is during the day, the usage demand of the terminal device is higher, and the first target threshold can be set to be larger. If it is at night, the usage demand of the terminal device is lower, and the first target threshold can be set to be larger. Optionally, the first target threshold can be pre-set during network deployment, or it can be independently selected by the network device within the optional value range based on factors such as device type.

[0143] In this embodiment, by obtaining the number of resident terminal devices on all beams, the sending period of all synchronization signal blocks in the synchronization signal block burst set of the target cell is increased, so as to reduce the energy consumption of the network device in sending the synchronization signal blocks and achieve the purpose of energy saving of the network device.

[0144] The second type: the number of data packets to be sent and / or received in all beam directions in the synchronization signal block burst set of the target cell is less than the second target threshold and / or the data transmission frequency is less than the third target threshold.

[0145] The number of data packets to be sent and / or received in all beam directions of the synchronization signal block burst set of the target cell is less than the second target threshold and / or the data transmission frequency is less than the third target threshold, which may include that only small packet data is transmitted on all beams with the synchronization signal block burst set position parameter set to 1 or the interval between two data transmissions is relatively large. At this time, the target cell can notify the terminal device to transfer the data service to the cell corresponding to the adjacent base station in advance, and then the target cell can cancel or increase the transmission period of certain synchronization signal blocks.

[0146] In this embodiment, the target cell can cancel or increase the sending period of certain synchronization signal blocks to reduce the energy consumption of the base station corresponding to the target cell in sending synchronization signal blocks, thereby achieving the purpose of energy saving of network equipment.

[0147] The third type: the number of UEs residing in at least one beam direction of the synchronization signal block burst set in the target cell is less than the fourth target threshold.

[0148] The number of UEs residing in at least one beam direction in the synchronization signal block burst set in the target cell is less than a fourth target threshold, which mainly means that the number of terminal devices interacting with the network device on at least one beam with the synchronization signal block burst set position parameter set to 1 is less than the fourth target threshold. The fourth target threshold may be related to the time period in which the terminal currently operates, such as whether the terminal operates during the day or at night. The fourth target threshold may be pre-set during network deployment, or may be autonomously selected by the network device within an optional value range based on factors such as device type.

[0149] In this embodiment, by obtaining the number of terminal devices resident on at least one beam, the sending period of the synchronization signal block in a certain beam direction of the target cell can be increased, so as to reduce the energy consumption of the network device in sending the synchronization signal block and achieve the purpose of energy saving of the network device.

[0150] The fourth type: the number of data packets to be sent and / or received in at least one beam direction in the synchronization signal block burst set in the target cell is less than the fifth target threshold and / or the data transmission frequency is less than the sixth target threshold.

[0151] In this embodiment, the number of data packets to be sent and / or received in at least one beam direction in the synchronization signal block burst set in the target cell can be compared with the fifth target threshold and / or the data transmission frequency can be compared with the fourth target threshold, respectively, to obtain the transmission data packet size and / or transmission frequency in at least one beam direction in which the synchronization signal block burst set position parameter is set to 1, thereby effectively adjusting the number of terminal devices in a certain beam direction. Ultimately, the network device turns off beam transmission in certain beam directions in the target cell or increases the transmission period of beams in certain beam directions, thereby achieving the purpose of network energy saving.

[0152] Optionally, multiple target thresholds are involved in this embodiment. For example, a first target threshold and a second target threshold can be set according to usage requirements. The terms "first" and "second" do not imply a sequence of targets or numerical values.

[0153] Optionally, the target cell may be a coverage area of ​​the network device, and the network device communicates with the terminal device within the target cell.

[0154] At least one beam direction in a synchronization signal block (SSB) burst set (Burst Set) may refer to the direction in which one or more synchronization signal blocks in a synchronization signal block having a position parameter of the synchronization signal block burst set set set set set set is sent and received. In the present disclosure, a first preset condition may be determined for at least one beam direction in a synchronization signal block having a position parameter of the synchronization signal block burst set set set set set to increase the period of some beams in the synchronization signal block burst set or cancel the transmission of some beams in the synchronization signal block burst set, thereby achieving energy saving of the network device.

[0155] All beam directions in a synchronization signal block burst set may refer to directions in which all synchronization signal blocks in a synchronization signal block having a position parameter of the synchronization signal block burst set set set is sent and received. In the present disclosure, a first preset condition may be judged on all beam directions in a synchronization signal block having a position parameter of the synchronization signal block burst set set set set to simultaneously increase the period of all beams in the synchronization signal block burst set or cancel the sending of all beams in the synchronization signal block burst set to achieve energy saving of a network device.

[0156] Optionally, entering the energy-saving state may specifically include at least one of the following:

[0157] The first energy-saving state: the sending period of at least one synchronization signal block in the synchronization signal block burst set of the target cell is increased to the target period and the sending period of at least one synchronization signal block in the synchronization signal block burst set of the target cell remains unchanged.

[0158] By increasing the sending period of the synchronization signal blocks, the network device can reduce the frequency of sending the synchronization signal blocks, increase the sleep time of the network device, and thus reduce the energy consumption of the network device.

[0159] In this embodiment, by increasing the sending period of at least one synchronization signal block in the synchronization signal block burst set of the target cell to the target period and maintaining the sending period of at least one synchronization signal block unchanged, it is possible to prioritize increasing the sending period of the synchronization signal blocks in the idle state when some synchronization signal blocks are in a busy state and some synchronization signal blocks are in an idle state, so as to maximize the energy saving of network equipment without affecting the communication of the synchronization signal blocks in the busy state.

[0160] The second energy-saving state: at least one synchronization signal block in the synchronization signal block burst set of the target cell is canceled and the transmission period of at least one synchronization signal block in the synchronization signal block burst set of the target cell remains unchanged.

[0161] Canceling the transmission of at least one synchronization signal block may refer to canceling the transmission of synchronization signal blocks in one or more beam directions within a synchronization signal block burst set. By reducing the number of synchronization signal blocks transmitted simultaneously within a period of time, the network device can reduce energy consumption of the network device, thereby achieving energy conservation.

[0162] In this embodiment, by canceling the transmission of at least one synchronization signal block in the burst set of the target cell and keeping the transmission period of at least one synchronization signal block in the burst set of the synchronization signal block of the target cell unchanged, it is possible to reduce the number of synchronization signal blocks that are in the idle state within a period of time when some synchronization signal blocks are in the busy state and some synchronization signal blocks are in the idle state, thereby achieving energy saving of network equipment.

[0163] The third energy-saving state: all synchronization signal blocks in the synchronization signal block burst set of the target cell are canceled.

[0164] The cancellation of sending of all synchronization signal blocks may refer to the cancellation of sending of all synchronization signal blocks with the synchronization signal block burst set position parameter set to 1, so as to minimize the energy consumption of the network device.

[0165] In this embodiment, by canceling the transmission of all synchronization signal blocks in the synchronization signal block burst set of the target cell, the base station corresponding to the target cell can be completely shut down or deactivated to achieve energy saving of network equipment.

[0166] The fourth energy-saving state: the sending period of all synchronization signal blocks in the synchronization signal block burst set of the target cell is increased to the target period.

[0167] Increasing the period of all synchronization signal blocks may mean simultaneously increasing the transmission period of all synchronization signal blocks whose synchronization signal block burst set position parameters are set to 1. Increasing the period of the synchronization signal blocks can reduce the frequency at which the network device transmits synchronization signal blocks, effectively reducing the energy consumption of the network device.

[0168] In this embodiment, by increasing the sending period of all synchronization signal blocks in the synchronization signal block burst set of the target cell to the target period, the frequency of network equipment sending synchronization signal blocks can be reduced and the sleep time of the network equipment can be increased, so as to achieve the purpose of reducing the energy consumption of the network equipment.

[0169] Optionally, the first downlink information can indicate that the terminal device has entered the energy-saving state, as well as the specific implementation method of the network device entering the energy-saving state. Optionally, the network device can indicate whether the transmission period of the synchronization signal block of the terminal device is increased or whether the transmission of the synchronization signal block is canceled, as well as the specific index of the synchronization signal block whose period is increased or whose transmission is canceled, through the first downlink information, to achieve matching of the energy-saving state operations of the network device and the terminal device.

[0170] 4 , the network device may send first downlink information to the terminal device in the target cell.

[0171] Optionally, the first downlink information may include downlink control information (Downlink Control Information, DCI for short).

[0172] Optionally, the first downlink information may include at least one of the following:

[0173] An energy indication field for indicating the energy consumption status of the target cell;

[0174] A period field for indicating a transmission period of at least one synchronization signal block of the target cell;

[0175] The synchronization signal block index field is used to indicate the synchronization signal block index of the target cell.

[0176] In this embodiment, the network device sends the first downlink information to the terminal device of the target cell, so that the terminal device can transfer the service transmission in all or at least one synchronization signal block direction to the cell corresponding to the adjacent base station or other synchronization signal block direction in advance, so as to better match the energy-saving state processing of the current target cell, and thus better achieve energy saving of the network device.

[0177] As shown in FIG5 , a flowchart of a processing method according to the second embodiment of the present application is shown, which can be applied to a terminal device. The method may include:

[0178] Step S10: Receive downlink information.

[0179] Step S20: Obtain the actual sending period of at least one synchronization signal block in the synchronization signal block burst set according to the downlink information.

[0180] Optionally, the downlink information in step S10 in this embodiment may include first downlink information.

[0181] Referring to Figure 4, after the network device sends the first downlink information, the terminal device executes step S10 which may specifically include step S101: receiving the first downlink information, and step S20 may specifically include step S201: obtaining the actual sending period of at least one synchronization signal block in the synchronization signal block burst set according to the first downlink information.

[0182] Optionally, the downlink information in step S10 may further include second downlink information.

[0183] Optionally, the second downlink information may include at least one of the following:

[0184] An energy indication field for indicating the energy consumption status of the target cell;

[0185] A period field for indicating a transmission period of at least one synchronization signal block of the target cell;

[0186] The synchronization signal block index field is used to indicate the synchronization signal block index of the target cell.

[0187] Optionally, the second downlink information may also be traditional downlink control information that does not include any of the energy indication field, the period field, and the synchronization signal block index field.

[0188] Optionally, the terminal device can quickly obtain the actual sending period of each synchronization signal block through the first or second downlink information, so that the terminal device can quickly match the specific processing of the energy-saving state of the network device to better achieve the energy-saving purpose of the network device.

[0189] Optionally, the terminal device can obtain the synchronization signal block index of the synchronization signal burst set whose period needs to be adjusted and the direction of adjustment of the synchronization signal block period based on the first downlink information. For example, the terminal device can determine the adjustment direction such as increasing the synchronization signal block period or directly canceling the sending of this synchronization signal block based on the first downlink information.

[0190] Optionally, the terminal device can also restore the sending period of at least one synchronization signal block in the synchronization signal block burst set based on the second downlink information to alleviate the scenario where the terminal device has poor transmission quality on certain beams or the service cannot be transmitted normally in certain cells.

[0191] In this embodiment, after the network device transmits downlink information, the terminal device may receive the downlink information sent by the network device. The downlink information may control the actual transmission period of at least one synchronization signal block in a synchronization signal block burst set. This may reduce the number of synchronization signal blocks sent by the network device over a period of time by increasing the transmission period of the synchronization signal block or canceling the transmission of the synchronization signal block, thereby reducing energy consumption of the network device.

[0192] Optionally, step S20: obtaining, according to the downlink information, an actual transmission period of at least one synchronization signal block in the synchronization signal block burst set may include at least one of the following during specific execution:

[0193] Obtaining the actual transmission period of all synchronization signal blocks in the synchronization signal block burst set according to the energy indication field and the period field;

[0194] Acquire an actual sending period of at least one synchronization signal block in a synchronization signal block burst set according to the energy indication field, the period field, and the synchronization signal block index field;

[0195] The actual sending period of at least one synchronization signal block in the synchronization signal block burst set is obtained according to the energy indication field and the synchronization signal block index field.

[0196] Optionally, obtaining the actual transmission period of all synchronization signal blocks in the synchronization signal block burst set based on the energy indication field and the period field may include: obtaining whether the network device is currently in an energy-saving state or a normal transmission state based on the energy indication field in the downlink control information (DCI), and then obtaining the specific transmission period of the network device in the subsequent energy-saving or normal state based on the period field. The transmission period adjustment in this solution can be for all synchronization signal blocks for which the synchronization signal block burst set position parameter is set to 1.

[0197] Optionally, obtaining the actual transmission period of at least one synchronization signal block in the synchronization signal block burst set based on the energy indication field, the period field and the synchronization signal block index field may include increasing the transmission period of these relatively idle beams in all beams set to 1 in the synchronization signal block burst set, when there may be some beams on which no or only a few terminals perform data transmission, so as to minimize the energy consumption of the network device.

[0198] Optionally, obtaining the actual transmission period of at least one synchronization signal block in a synchronization signal block burst set based on the energy indication field and the synchronization signal block index field may include canceling the transmission period of some relatively idle beams in all beams whose bits are set to 1 in the synchronization signal block burst set, thereby achieving energy saving for the network device. Compared to increasing the transmission period of relatively idle beams, this solution can better reduce network device energy consumption and reduce the number of bits of downlink control information sent by the network device.

[0199] In this embodiment, the actual sending period of all synchronization signal blocks in the synchronization signal block burst set can be obtained according to the energy indication field and period field in the downlink information.

[0200] Optionally, the downlink information may include first downlink information or second downlink information.

[0201] Optionally, the first downlink information may include at least one of the following:

[0202] An energy indication field for indicating the energy consumption status of the target cell;

[0203] A period field for indicating a transmission period of at least one synchronization signal block of the target cell;

[0204] The synchronization signal block index field is used to indicate the synchronization signal block index of the target cell.

[0205] In this embodiment, the following downlink information is used as the first downlink information to explain how to use the first downlink information to indicate at least one of the energy indicator field, period field, and synchronization signal block index field to constrain the sending period of at least one synchronization signal block in the synchronization signal block burst set, so as to achieve matching processing of sending and receiving of network equipment and terminal equipment in an energy-saving state, and better achieve energy saving of network equipment.

[0206] Optionally, the energy indication field in the first downlink information may occupy one bit. Optionally, if the energy indication field is set to "0", it indicates that the current target cell is in a normal state, and if the energy indication field is set to "1", it indicates that the current target cell is in an energy-saving state.

[0207] Optionally, the period field (Period) in the first downlink information may occupy three bits. Different bit value combinations may indicate different synchronization signal block transmission periods. For example, 000 may indicate a period of 5 ms, 001 may indicate a period of 10 ms, 010 may indicate a period of 20 ms, 011 may indicate a period of 40 ms, 100 may indicate a period of 80 ms, and 101 may indicate a period of 160 ms.

[0208] Optionally, different bit value combinations may also indicate that the synchronization signal block transmission period in the energy-saving state is a multiple of the synchronization signal block transmission period of the current high-level configuration. For example, 000 may indicate that the synchronization signal block transmission period in the energy-saving state is 1 times the synchronization signal block transmission period of the current high-level configuration, 001 may indicate that the synchronization signal block transmission period in the energy-saving state is 2 times the synchronization signal block transmission period of the current high-level configuration, 010 may indicate that the synchronization signal block transmission period in the energy-saving state is 4 times the synchronization signal block transmission period of the current high-level configuration, 011 may indicate that the synchronization signal block transmission period in the energy-saving state is 8 times the synchronization signal block transmission period of the current high-level configuration, and so on.

[0209] Of course, the bit length of the above period and the specific period duration corresponding to the bit value selection method can be set according to usage requirements. The above is only exemplary and should not constitute a specific limitation on the technical solution of the present disclosure.

[0210] Optionally, the energy consumption state of the target cell may include an energy-saving state and a normal state. In the energy-saving state, the base station can effectively reduce the number of synchronization signal blocks sent to reduce energy consumption. In the normal state, the base station maintains a normal number of synchronization signal blocks sent and service processes, and the network energy consumption is normal.

[0211] Optionally, in this technical solution, a Synchronization Signal Block Burst set (SSB burst set) may include at most 64 candidate Synchronization Signal Block (SSB) positions. Taking an SSB Burst set containing 8 candidate SSBs as an example, the high-layer parameter Synchronization Signal Block Burst set position parameter (ssb-PositionsInBurst) may include 8 bits, each bit may refer to a candidate SSB, and each candidate SSB may include an SSB identifier, and the SSB identifier may be represented by a position number. For example, the first position parameter may be SSB#1, the second position parameter may be SSB#2, and so on. For example, if ssb-PositionsInBurst is set to '01101010', it means that only 4 of the 8 candidate SSBs in a Synchronization Signal Block Burst set are actually transmitted, which are SSB#2, SSB#3, SSB#5, and SSB#7 respectively.

[0212] Optionally, all candidate Synchronization Signal Blocks in a Synchronization Signal Block Burst set may be transmitted within 5 ms (millisecond).

[0213] Optionally, the transmission of all Synchronization Signal Blocks in a Synchronization Signal Block Burst set may be cancelled according to the energy indication field.

[0214] Optionally, when the carrier frequency f satisfies 3 GHz < f <= 6 GHz, an SSB Burst set contains 8 candidate SSBs. If the high-layer parameter Synchronization Signal Block Burst set position (ssb-PositionsInBurst) = '01101010', then only the beam directions corresponding to 4 SSBs among the 8 candidate SSBs are used for data transmission and reception. If the energy indication field in the first downlink information received by the terminal device is 1, it means that the base station has entered the energy-saving state and no longer performs any Synchronization Signal Block transmission.

[0215] Optionally, the actual transmission period of all Synchronization Signal Blocks in a Synchronization Signal Block Burst set may be obtained according to the energy indication field and the period field.

[0216] Optionally, if the carrier frequency f satisfies 3 GHz < f <= 6 GHz, one SSB Burst set contains 8 candidate SSBs. If the high-layer parameter Synchronization Signal Block Burst Set Position (ssb-PositionsInBurst) = '01101010', then only the beam directions corresponding to 4 SSBs among the 8 candidate SSBs are used for data transmission and reception. These 4 synchronization signal blocks are SSB#2, SSB#3, SSB#5, and SSB#7 (the positions marked in gray in Table 1) as shown in Table 1 below:

[0217] Table 1

[0218] SSB#1SSB#2SSB#3SSB#4SSB#5SSB#6SSB#7SSB#8

[0219] Assume that the high-layer parameter Synchronization Signal Period of the serving cell (ssb-periodicityServingCell) configures the normal transmission period of the SSB to be 20 ms. If the energy indicator field (energy indicator) in the Downlink Control Information (DCI) is set to '1' and the period field (Period) is set to '100', and when the period field is '100', it represents that the SSB transmission period is 80 ms, then after receiving the first downlink information containing the energy indicator field and the period field, the terminal device will learn that the current base station enters the energy-saving state, and the transmission periods of the synchronization signal blocks SSB#2, SSB#3, SSB#5, and SSB#7 increase from the original period of 20 ms to 80 ms. The network device can reduce the transmission energy consumption of the base station and achieve network energy saving by increasing the transmission periods of all the synchronization signal blocks with 1 set in the synchronization signal block burst set position parameter.

[0220] For ease of understanding, Figure 6 gives a schematic diagram of the increase in the transmission period of a synchronization signal block. In the schematic diagram, the horizontal axis is the time axis, and the vertical axis is the resource block size of the frequency domain resources occupied by the synchronization signal block. 601 in the schematic diagram represents the transmission period interval of the synchronization signal block when the base station is in the normal state, where the interval size is 20 ms; 602 in the schematic diagram represents the transmission period interval of the synchronization signal block when the base station is in the energy-saving state, where the interval size increases from 20 ms to 80 ms. It can be seen from Figure 6 that the base station in the normal state needs to transmit the synchronization signal block four times in 80 ms, while in the energy-saving state, the base station only needs to transmit the synchronization signal block once in 80 ms. That is, when the base station is in the energy-saving state, it can reduce the number of synchronization signal blocks transmitted per unit time by increasing the transmission period of the synchronization signal block, thereby reducing the energy consumption of the network device and achieving the purpose of network energy saving.

[0221] Optionally, the base station can also directly cancel the transmission of a synchronization signal block, as shown in Figure 7. 701 in Figure 7 indicates that when the base station is in a normal state, the transmission period of the synchronization signal block is 20ms. 702 in Figure 7 indicates that when the base station meets the first preset condition, it enters an energy-saving state, at which point the transmission of the synchronization signal block is directly canceled. In other words, in the energy-saving state shown in 602 in Figure 7, the base station directly cancels the transmission of the synchronization signal block to reduce network device energy consumption.

[0222] Optionally, the network device can also simultaneously increase the sending period of all synchronization signal blocks in a synchronization signal block burst set or cancel the sending of all synchronization signal blocks in a synchronization signal block burst set, and notify the terminal device of its specific synchronization signal block transmission processing operations in the energy-saving state through the energy indication field and period field in the first downlink information.

[0223] Optionally, the first downlink information may further include a synchronization signal block index field, and the first number of bits occupied by the synchronization signal block index field may be equal to the second number of bits of the synchronization signal block burst set position parameter set to 1.

[0224] Optionally, if the number of bits set to 1 in the synchronization signal block burst set position parameter is 4, the number of bits occupied by the newly added synchronization signal block index field in the first downlink information is also 4.

[0225] In this embodiment, by setting the first number of bits occupied by the synchronization signal block index field equal to the second number of bits of the synchronization signal block burst set position parameter to 1, compared to setting the first number of bits occupied by the synchronization signal block index field to the number of candidate synchronization signal blocks, more downlink control information bits are saved, and the purpose of notifying the terminal base station how to handle the synchronization signal block when it is in an energy-saving state can also be achieved.

[0226] Optionally, the synchronization signal block burst set position parameter refers to the high-level parameter ssb-PositionsInBurst, and only the beam transmission direction corresponding to the synchronization signal block corresponding to the bit set to 1 in ssb-PositionsInBurst is used by the terminal for data reception and transmission.

[0227] Optionally, the actual sending period of at least one synchronization signal block in the synchronization signal block burst set can be obtained based on the energy indication field and the synchronization signal block index field.

[0228] For example, if the carrier frequency f satisfies: 3 GHz < f <= 6 GHz, then one SSB set contains 8 candidate SSB positions. If the high-layer parameter ssb-PositionsInBurst = '01101010', then the number of the second bits set to 1 in the synchronization signal block burst set position parameter is 4. Also, because the number of the first bits occupied by the synchronization signal block index field is equal to the number of the second bits set to 1 in the synchronization signal block burst set position parameter, the synchronization signal block index field occupies 4 bits.

[0229] Optionally, each bit of the synchronization signal block index field may respectively refer to the transmission state of the signal block whose corresponding bit in the synchronization signal block burst set position parameter is set to 1.

[0230] Optionally, if the value of the target bit position of the synchronization signal block index field is 1, the corresponding synchronization signal block in the synchronization signal block burst set position parameter is cancelled from being transmitted.

[0231] Optionally, if the value of the target bit position of the synchronization signal block index field is 0, the corresponding synchronization signal block in the synchronization signal block burst set position parameter maintains the original period and is normally transmitted.

[0232] For ease of understanding, still taking ssb-PositionsInBurst set to '01101010' as an example, that is, among the 8 candidate synchronization signal blocks, only the beam directions corresponding to SSB#2, SSB#3, SSB#5, and SSB#7 are used for data transmission between the terminal and the network device. Since the number of the first bits occupied by the synchronization signal block index field is equal to the number of the second bits set to 1 in the synchronization signal block burst set position parameter, the number of bits occupied by the synchronization signal index block is 4, and its first bit refers to SSB#2 in the synchronization signal block burst set, the second bit refers to SSB#3 in the synchronization signal block burst set, the third bit corresponds to SSB#5 in the synchronization signal block burst set, and the fourth bit refers to SSB#7 in the synchronization signal block burst set. The value of the bit position of the synchronization signal index block can perform transmission control on the corresponding synchronization signal block in the synchronization signal block burst set position set parameter. For example, if the bit is set to 1, the corresponding synchronization signal block is cancelled from being transmitted; if the bit is set to 0, the corresponding synchronization signal block maintains normal periodic transmission. For example, if the synchronization signal block index field "SS / PBCH index" is set to "0110", it can be determined that among SSB#2, SSB#3, SSB#5, and SSB#7, the synchronization signal blocks corresponding to SSB#3 and SSB#5 are cancelled from being transmitted, while the synchronization signal blocks corresponding to SSB#2 and SSB#5 maintain normal periodic transmission.

[0233] Optionally, the actual transmission period of at least one synchronization signal block in the synchronization signal block burst set can be obtained according to the energy indication field, the period field, and the synchronization signal block index field.

[0234] Optionally, each bit of the synchronization signal block index field can respectively refer to the transmission status of the signal blocks with the position parameter set to 1 in the synchronization signal block burst set.

[0235] Optionally, if the target bit of the synchronization signal block index field has a value of 1, the transmission period of the corresponding synchronization signal block in the synchronization signal block burst set position parameter is increased to the period value indicated by the period field.

[0236] Optionally, if the target bit of the synchronization signal block index field has a value of 0, the corresponding synchronization signal block in the synchronization signal block burst set position parameter maintains its original period and is transmitted normally.

[0237] For ease of understanding, it is also assumed that the carrier frequency f satisfies: 3 GHz < f <= 6 GHz. Then, an SSB set contains 8 candidate SSB positions. If the field ssb-PositionsInBurst is set to '01101010', it indicates that only the beam directions corresponding to SSB#2, SSB#3, SSB#5, and SSB#7 among the 8 candidate synchronization signal blocks are used for data transmission between the terminal and the network device. Since the number of the first bits occupied by the synchronization signal block index field is equal to the number of the second bits with the synchronization signal block burst set position parameter set to 1, the number of bits occupied by the synchronization signal index block can be 4. And its first bit refers to SSB#2 in the synchronization signal block burst set, the second bit refers to SSB#3 in the synchronization signal block burst set, the third bit refers to SSB#5 in the synchronization signal block burst set, and the fourth bit refers to SSB#7 in the synchronization signal block burst set. The value of the bit of the synchronization signal index block can perform transmission control on the corresponding synchronization signal block in the synchronization signal block burst set position set parameter. For example, if the bit is set to 1, the transmission period of the corresponding synchronization signal block is increased to the period indicated by the period field in the downlink information. If the bit is set to 0, the corresponding synchronization signal block maintains the normal period for transmission. For example, if the synchronization signal block index field "SS / PBCH index" is set to "0110" and the period indication field is set to "100" corresponding to the SSB transmission period of 80 ms, and the high-layer parameter ssb-periodicityServingCell is set to '20 ms', it can be determined that among SSB#2, SSB#3, SSB#5, and SSB#7, the transmission periods of the synchronization signal blocks corresponding to SSB#3 and SSB#5 are increased to 80 ms, while the synchronization signal blocks corresponding to SSB#2 and SSB#5 maintain the normal period for transmission.

[0238] Optionally, by limiting the number of SSBs transmitted per transmission, multiple candidate positions in a single synchronization signal block burst set can be dispersed across multiple transmission cycles, thereby increasing the synchronization signal block transmission period and reducing the energy of the synchronization signal block transmitted by the base station each time, thereby achieving energy conservation for network equipment. For example, the fixed number of SSBs that can be transmitted per transmission cycle can be set to N1, and the number of SSBs actually transmitted based on the number of 1s in the synchronization signal block burst set position parameter can be set to N2. The number of SSBs that can be transmitted at the transmission position in each SSB period is then set to a value less than or equal to the minimum of N1 and N2.

[0239] If ssb-PositionsInBurst is set to '01111110', the number of SSBs actually transmitted among the 8 candidate SSBs, N2, can be 6. Assume that the fixed number of SSBs that can be sent in each transmission cycle, N1, can be 4. Therefore, the number of SSBs that can be sent in each SSB cycle is N=min(N1,N2), and the value of N can be 4, that is, the number of candidate positions in the SSB set of a single transmission is 4. Then, the 6 SSBs that are actually transmitted among the 8 candidate SSBs are fully transmitted through ceil(N2 / N) cycles, and the 6 real SSBs can only be fully transmitted in the existing 2 SSB cycles. Optionally, the number of SSBs sent in the first SSB transmission cycle can be set to N=4, and the number of SSBs sent in the second SSB transmission cycle can be set to the remaining N1-N=2.

[0240] For ease of understanding, as shown in the example index setting diagram in Figure 8, ssb-PositionsInBurst can be set to '01111110' and ssb-periodicityServingCell can be set to 20ms. This means the SSB transmission period is 20ms, and the actual number of SSBs transmitted, N2, is, for example, 6. If the fixed number of SSBs that can be transmitted per transmission period, N1, is set to 4, for example, then the maximum number of SSBs transmitted per SSB period is N = min(N1, N2), where N can be 4. Alternatively, as shown in the example indexing device diagram in Figure 9, the first four sync signal blocks (SSBs) can be transmitted: SSB#2, SSB#3, SSB#4, and SSB#5; the second transmission period includes the remaining sync signal blocks (SSB#6 and SSB#7). By limiting the number of SSBs transmitted per transmission, the sync signal block transmission period in the sync signal block burst position parameter can be increased without changing the downlink control information carrying bits. This reduces the energy consumption of the base station during each sync signal block transmission, thus achieving energy conservation for network equipment.

[0241] Optionally, when increasing the transmission period of the synchronization signal block by limiting the number of SSBs transmitted each time, there is no need to increase the carrying bits in the downlink control information, but the purpose of saving network energy consumption can still be achieved.

[0242] Optionally, limiting the number of SSBs transmitted each time can also be combined with at least one of the energy indication field, period field and / or synchronization signal block index field in the downlink information according to the scheme described in the above embodiment to further reduce network energy consumption.

[0243] It can be seen from the above embodiments that when the network device enters the energy-saving state, the energy of the base station sending the synchronization signal block can be reduced by canceling the sending of all synchronization signal blocks in the synchronization signal block burst set, increasing the sending period of all synchronization signal blocks in the synchronization signal block burst set, increasing the sending period of at least one synchronization signal block in the synchronization signal block burst set, canceling the sending of at least one synchronization signal block in the synchronization signal block burst set, or limiting the synchronization signal blocks in the synchronization signal block burst set transmitted each time. The terminal device can receive the first downlink information sent by the network device before entering the energy-saving state to obtain the specific synchronization signal block sending processing method of the base station in the energy-saving state, so as to better match the service transmission in the network energy-saving state. However, because the number of terminals or services that a certain base station can handle is limited, when the business volume suddenly increases or the number of terminals within the deployment range of the base station increases significantly, the base station serving these terminals cannot always be in the energy-saving state, that is, the base station needs to switch to a normal working state.

[0244] Optionally, after the base station enters the energy-saving state, the terminal may send an uplink wake-up signal based on a third preset condition to wake up the base station.

[0245] As shown in FIG10 , it is a flow chart of the processing method shown in the third embodiment of the present application.

[0246] The terminal device can execute step S30 and send an uplink wake-up signal in response to meeting the third preset condition, where the uplink wake-up signal is used to determine the number of UEs residing in at least one beam direction in the synchronization signal block burst set in the target cell.

[0247] In this embodiment, the terminal device initiates switching of the network device by sending an uplink wake-up signal, thereby implementing energy consumption state switching executed according to the usage requirements of the terminal device and achieving fast and effective switching of the energy consumption state.

[0248] Optionally, the third preset condition is satisfied, including at least one of the following:

[0249] The reference signal received power of the synchronization signal / physical broadcast channel block of the terminal device in the current serving cell is lower than the eighth target threshold;

[0250] The cumulative number of times that the terminal device transmits the preamble code at the current service cell reaches the maximum number of transmissions is greater than the ninth target threshold.

[0251] Optionally, the current serving cell may be a cell that can also be covered by a base station in an energy-saving state.

[0252] The Reference Signal Received Power (RSRP) of the synchronization signal / physical broadcast channel block of the current serving cell represents a key parameter of wireless signal strength and physical layer measurement requirements in LTE or 5G networks. If the RSRP is too low, it indicates that the current serving base station is far away from the terminal device, resulting in a high packet error rate and the terminal device needs to switch to a closer serving base station.

[0253] The event that the number of preamble code transmissions reaches the maximum number of transmissions may mean that the number of times the preamble code is sent is greater than the maximum number of transmissions configured by the high-level parameters. This scenario usually occurs when there are too many terminal devices connected to the current service base station and the base station load is too heavy. The terminal device needs to initiate random access to other closer service base stations to ensure the normal transmission of business data.

[0254] In this embodiment, the terminal device can initiate an uplink wake-up signal to the network device when the reference signal reception power of the synchronization signal / physical broadcast channel block of the current serving cell is lower than the eighth target threshold. Optionally, the terminal device can also initiate an uplink wake-up signal to the network device when the number of occurrences of the event that the number of transmissions of the preamble code in the current serving cell reaches the maximum number of transmissions is greater than the ninth target threshold. After receiving the uplink wake-up signal sent by the terminal device, the base station determines whether to switch from the energy-saving state to the normal state based on the second preset condition, and then restores the normal service transmission function.

[0255] It should be noted that this technical solution involves multiple thresholds, such as a first target threshold and a second target threshold. These different thresholds are used to determine the numerical values ​​of different parameters and can be determined based on the judgment requirements of each parameter. Setting thresholds for each parameter can have a corresponding impact on the results of different parameters, thereby improving the accuracy of threshold judgments.

[0256] In some embodiments, referring to FIG. 10 , after the terminal device executes step S30 , the network device may execute step S2 : receiving an uplink wake-up signal.

[0257] Optionally, the uplink wake-up signal includes at least one of the following:

[0258] Terminal identification;

[0259] A specific sync signal block index;

[0260] A specific synchronization signal block period;

[0261] preamble sequence;

[0262] Tracking reference signal sequence;

[0263] A DMRS-like (Demodulation Reference Signal) sequence carried in the PUSCH.

[0264] Optionally, the uplink wake-up signal may be a periodic signal, that is, sent at a fixed period position.

[0265] Optionally, the uplink wake-up signal may also be sent in each time slot or each subframe.

[0266] Optionally, the terminal identifier may be a type identifier of the terminal device or a terminal ID (UE ID) of the terminal device.

[0267] Optionally, the base station may determine the number of UEs residing in at least one beam direction in the synchronization signal block burst set in the target cell through the uplink wake-up signal sent by the terminal.

[0268] In this embodiment, the network device receives the uplink wake-up signal sent by the terminal device to better understand the usage demand of the terminal device in the cell served by the base station, and better achieves a balance between energy saving and service transmission based on the demand of the terminal device in the cell served by the base station, thereby improving the energy consumption control accuracy and efficiency of the network device.

[0269] 10 , the network device may further perform step S3: in response to satisfying the second preset condition, send second downlink information and enter a normal state. The second downlink information may be sent by the network device to the terminal device.

[0270] In this embodiment, after switching to the energy-saving state, the network device may enter the normal state if the second preset condition is met.

[0271] Optionally, FIG11 is an example diagram of a transition to a normal state. As shown in FIG11 , the terminal device 1102 may send an uplink wake-up signal (WUS) to the network device 1101.

[0272] The network device 1101 may switch from the energy-saving state to the normal state according to the second preset condition, and simultaneously send the second downlink information to the terminal device 1102 .

[0273] Optionally, the second preset condition is satisfied, including at least one of the following:

[0274] The first type of satisfying the second preset condition may include: the number of UEs residing in all beam directions in the synchronization signal block burst set in the target cell is greater than or equal to the first target threshold.

[0275] The network device may determine the number of UEs that will reside in the direction of a beam based on the number of terminal IDs in the uplink wake-up signal received on the beam. If the number of UEs residing on all beams in the synchronization signal block burst set is greater than or equal to the first target threshold, the network device may switch from the energy-saving state to the normal state.

[0276] Optionally, the number of terminal devices residing in all beam directions is greater than or equal to a first target threshold, which may include the total number of terminal devices obtained by summing the number of terminal devices residing in each beam direction being greater than or equal to the first target threshold, or the maximum number of terminal devices residing in each beam direction is greater than or equal to the first target threshold, or the number of terminal devices residing in each beam direction is greater than or equal to the first target threshold.

[0277] In this embodiment, the network device achieves a balance between network energy saving and business transmission services by determining that the number of UEs residing in all beam directions in the synchronization signal block burst set in the target cell is greater than or equal to the first target threshold.

[0278] The second type of satisfying the second preset condition may also include: the number of data packets to be sent and / or received in all beam directions of the synchronization signal block burst set in the target cell is greater than or equal to the second target threshold and / or the data transmission frequency is greater than or equal to the third target threshold.

[0279] The number of data packets may include the number of data packets that the network device plans to transmit and the number of data packets that the terminal device is ready to send. Optionally, the number of data packets that the terminal device is ready to send may be carried in the uplink wake-up signal to indicate the number of data packets that the network device plans to send.

[0280] The data transmission frequency may refer to the number of data packets received and / or sent per unit time. The unit time may be one time slot, one subframe, one radio frame, or other counting units.

[0281] In this embodiment, the network device can perform threshold judgment based on the number of data packets received and / or sent and / or the frequency of data transmission in all beam directions, thereby detecting and judging the data transmission needs in all beam directions, and using the data transmission needs to accurately control the network device, thereby improving control efficiency and accuracy.

[0282] The third type of satisfying the second preset condition may include: the number of UEs residing in at least one beam direction in the synchronization signal block burst set in the target cell is greater than or equal to the fourth target threshold.

[0283] The number of UEs residing in at least one beam direction within the synchronization signal block burst set may include the number of terminal IDs that send uplink wake-up signals in at least one beam direction.

[0284] In this embodiment, the network device controls the granularity of the synchronization signal blocks sent by the base station within a beam range by making a threshold judgment on the number of UEs residing in some beam directions, which can better reduce the energy of the synchronization signal blocks sent by the base station and achieve energy saving of the network device.

[0285] The fourth type of meeting the second preset condition may include: the number of data packets to be sent and / or received in at least one beam direction in the synchronization signal block burst set in the target cell is greater than or equal to the fifth target threshold and / or the data transmission frequency is greater than or equal to the sixth target threshold.

[0286] Optionally, all beam directions refer to beam directions corresponding to all synchronization signal blocks whose synchronization signal block burst set position parameters are set to 1. The synchronization signal blocks for all beam directions are processed with one synchronization signal block burst set as a unit.

[0287] Optionally, the at least one beam direction refers to a beam direction corresponding to one or more synchronization signal blocks whose synchronization signal block burst set position parameter is set to 1. The synchronization signal blocks for the at least one beam direction are processed as a unit using one beam in a synchronization signal block burst set.

[0288] In this embodiment, the network device detects the data transmission needs of the network device from some beam directions by comparing the number of data packets to be sent and / or received and / or the data transmission frequency in at least one beam direction in the synchronization signal block burst concentration in the target cell with the fourth target threshold. By detecting the data transmission needs in some beam directions, more accurate energy consumption status control can be achieved. When there is a large data transmission demand in some beam directions, transmission can be initiated, and the accuracy of the data transmission demand setting can be improved.

[0289] Optionally, entering the normal state includes at least one of the following:

[0290] The transmission period of at least one synchronization signal block with the bit set to 1 in the synchronization signal block burst set position parameter of the target cell is consistent with the period configured by the synchronization signal block period parameter of the serving cell;

[0291] The sending period of all synchronization signal blocks with bits set to 1 in the synchronization signal block burst set position parameter of the target cell is consistent with the period configured by the synchronization signal block period parameter of the serving cell.

[0292] Optionally, the high-level parameter serving cell synchronization signal block period (ssb-periodicityServingCell) is used to configure the sending period of the synchronization signal blocks in the synchronization signal block burst set.

[0293] In this embodiment, the sending period of at least one synchronization signal block of the target cell is consistent with the period configured by the synchronization signal block period parameter of the serving cell, and / or the sending period of all synchronization signal blocks with bits set to 1 in the burst set position parameter of the target cell is consistent with the period configured by the synchronization signal block period parameter of the serving cell. By adjusting the settings of the sending period and / or the burst set position parameter, the period adjustment of the network device is achieved, thereby improving the efficiency and accuracy of the period adjustment of the network device.

[0294] Optionally, the target cell includes at least one of the following:

[0295] A secondary cell in carrier aggregation whose TA value belongs to the same timing advance group as the primary cell;

[0296] a secondary cell corresponding to a micro base station whose distance from the macro base station corresponding to the primary cell in carrier aggregation is less than a seventh target threshold;

[0297] Component carriers that do not carry downlink control information during cross-carrier scheduling in carrier aggregation;

[0298] The component carrier where the downlink control information in self-scheduling is located.

[0299] Optionally, a TA value (time advanced) can ensure that multiple terminal devices arrive at the base station at the same time.

[0300] Optionally, carrier aggregation (CA) refers to aggregating two or more component carriers (CCs) to support a larger transmission bandwidth.

[0301] Optionally, one cell in communication is equivalent to one component carrier.

[0302] The target cell may be a carrier aggregation cell whose TA value belongs to the same time advance group as the primary cell, which may mean that the TA value of the carrier corresponding to the target cell of the carrier aggregation and the TA value of the carrier corresponding to the primary cell belong to the same time advance group (Time Aadvance Group).

[0303] Optionally, base stations can be divided into macro base stations (Macro Site), micro base stations (Micro Site), etc. according to their coverage range / transmission power.

[0304] The target cell may be a secondary cell corresponding to a micro base station in carrier aggregation, the distance between the micro base station and the macro base station corresponding to the primary cell being less than a seventh target threshold.

[0305] The target cell may be a component carrier in carrier aggregation that does not carry downlink control information.

[0306] The target cell may be the component carrier where the downlink control information in the self-scheduling is located.

[0307] In this embodiment, after the target cell is determined, it can be determined based on a first preset condition whether the base station corresponding to the target cell is in an energy-saving state. If the base station corresponding to the target cell is in an energy-saving state, the service of the terminal served by the target cell can be switched to a service cell corresponding to another neighboring base station, thereby reducing the energy consumption of the base station serving the target cell. Optionally, a secondary cell whose TA value belongs to the same timing advance group as the primary cell in carrier aggregation can be set as the target cell. If the target cell meets the first preset condition, the base station corresponding to the target cell will enter an energy-saving state and notify the terminal device of the transmission mode of the synchronization signal block in the energy-saving state through downlink control information, thereby achieving matching between the energy-saving state of the network device and the terminal's transmission or reception processing.

[0308] 10 , in step S3 , after the network device sends the second downlink information, the terminal device executes step S10 : Receiving downlink information may specifically include step S102 : receiving the second downlink information.

[0309] Optionally, the terminal device may execute step S20 specifically including step S202: adjusting the receiving period of the synchronization signal block according to the period field and / or energy indication field in the received second downlink information.

[0310] In this embodiment, the terminal device can determine the energy consumption state of the network device according to the energy indication field in the received second downlink information.

[0311] The second downlink information may include at least one of the following:

[0312] An energy indication field for indicating the energy consumption status of the target cell;

[0313] A period field for indicating a transmission period of at least one synchronization signal block of the target cell;

[0314] The synchronization signal block index field is used to indicate the synchronization signal block index of the target cell.

[0315] In this embodiment, the terminal device learns from the second downlink information sent by the network device that the network device has returned to normal status and the specific processing operations of the synchronization signal block under the normal status of the network device, so as to better transmit data services with the network device.

[0316] Alternatively, the second downlink information may also be conventional physical downlink control information that does not include an energy indication field, a period field, or a synchronization signal block index field.

[0317] Alternatively, if the second downlink information includes an energy indication field and the energy indication field is set to 0, the synchronization signal block index field or the period field may also not exist.

[0318] Alternatively, the terminal device may obtain the power consumption status of the base station corresponding to the target cell only based on the energy indication field.

[0319] Alternatively, if the energy indication field in the second downlink information is set to zero, it can be known that the base station will perform normal SSB transmission according to the configurations of the high-layer parameters ssb-PositionsInBurst and ssb-periodicityServingCell in the next SSB period. For example, assuming that the carrier frequency f satisfies: 3 GHz < f <= 6 GHz, an SSB Burst set contains 8 candidate SSBs, the high-layer parameter ssb-PositionsInBurst is set to '01101010', and the high-layer parameter ssb-periodicityServingCell is set to 20 ms. In the next SSB period, the base station will continue to transmit SS / PBCH block #2, SS / PBCH block #3, SS / PBCH block #5, and SS / PBCH block #7 according to the original 20 ms period.

[0320] Alternatively, the terminal device may obtain the power consumption status of the base station corresponding to the target cell according to whether the received second downlink information includes an energy indication field, and further obtain the actual transmission period of the synchronization signal blocks in the synchronization signal block burst set.

[0321] Alternatively, if the received second downlink information does not include an energy indicator field, it can be considered that the base station corresponding to the current target cell is in a normal state, that is, the base station will perform normal SSB transmission according to the configurations of the high-layer parameters ssb-PositionsInBurst and ssb-periodicityServingCell.

[0322] Alternatively, the terminal device may obtain the power consumption status of the base station corresponding to the target cell according to the energy indication field and the synchronization signal block index field, and further obtain the actual transmission period of the synchronization signal blocks in the synchronization signal block burst set.

[0323] Optionally, if the second downlink information received by the terminal device includes both an energy indication field and a synchronization signal block index field, if the energy indication field is set to '1' but the synchronization signal block index is different from the synchronization signal block index of the first downlink information, the terminal can determine that although the base station is in a normal state, it only needs to resume transmission in the beam directions corresponding to certain synchronization signal blocks. For example, assume that the carrier frequency f satisfies: greater than the first frequency and less than or equal to the second frequency, the high-level parameter ssb-PositionsInBurst is set to '01101010', and the high-level parameter ssb-periodicityServingCell is set to 20ms.

[0324] Optionally, when the first preset condition is met, the base station corresponding to the target cell enters the energy saving state, and the energy indication field in the first downlink information is set to '1', and the synchronization signal block index is set to '0111'.

[0325] However, if the second preset condition is met, the base station corresponding to the target cell enters the normal state, the energy indication field in the first downlink information is set to '1', and the synchronization signal block index is set to '0100'. According to the first downlink information and the second downlink information, the terminal device cancels the transmission of synchronization signal blocks SSB#3, SSB#5, and SSB#7 in the energy-saving state; when the terminal device is in the normal state, only normal transmission of SSB#5 and SSB#7 is restored, and SSB#3 is still canceled.

[0326] Optionally, the terminal device can obtain the energy consumption status of the base station corresponding to the target cell based on the energy indication field, period field and synchronization signal block index field, and then obtain the actual sending period of the synchronization signal block in the synchronization signal block burst set.

[0327] Optionally, if the second downlink information received by the terminal device includes both an energy indication field and a synchronization signal block index field, then if the energy indication field is set to '1' but the synchronization signal block index is different from the synchronization signal block index of the first downlink information, the terminal device may know that although the base station is in a normal state, it only needs to restore transmission in the beam directions corresponding to certain synchronization signal blocks. For example, assume that the carrier frequency f satisfies: greater than the first frequency and less than or equal to the second frequency, the high-level parameter ssb-PositionsInBurst is set to '01101010', and the high-level parameter ssb-periodicityServingCell is set to 20ms.

[0328] Optionally, if the first preset condition is met, the base station corresponding to the target cell enters the energy saving state, and the energy indication field in the first downlink information is set to '1', the synchronization signal block index is set to '0111', and the period field is set to 80ms.

[0329] However, if the second preset condition is met, the base station corresponding to the target cell enters the normal state and the energy indication field in the first downlink information is set to '1', the synchronization signal block index is set to '0100', and the period field is set to 80ms. According to the first downlink information and the second downlink information, the terminal device increases the transmission period of synchronization signal blocks SSB#3, SSB#5, and SSB#7 from 20ms to 80ms in the energy-saving state; when the terminal device is in the normal state, only the period of SSB#5 and SSB#7 is restored from 80ms to 20ms, and SSB#3 still maintains the energy-saving transmission period of 80ms.

[0330] Optionally, the CRC scrambled RNTI value of the first downlink information or the second downlink information can be different from the existing RNTI (Radio Network Temporary Identity) value. For example, the RNTI of the first downlink information or the second downlink information is defined as SSB-RNTI and its value is any one of FFF3-FFFB. Optionally, FFF3 and FFFB are both hexadecimal values.

[0331] Optionally, a cyclic redundancy check (CRC) scrambled RNTI value of at least one of the first downlink information or the second downlink information may also be an RNTI value having the same value as SI (System Information)-RNTI or P (paging)-RNTI.

[0332] Optionally, the first downlink information or the second downlink information may be an existing downlink control information format (Downlink control information format, DCI format for short), for example, the first downlink information or the second downlink information may be DCI format 1_0, etc.

[0333] Optionally, if the first downlink information or the second downlink information is DCI format 1_0, and the system information radio network temporary identifier (SI-RNTI) is used for CRC scrambling, the energy indication field, period field, and synchronization signal block index field in the downlink information can occupy the reserved bits in DCI format 1_0.

[0334] Optionally, if the first downlink information or the second downlink information is DCI format 1_0 and P-RNTI is used for CRC scrambling, the energy indication field, period field, and synchronization signal block index field in the downlink information may occupy bits according to the following scenarios:
