[0082] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Furthermore, components, features, and elements with the same names in different embodiments of this application may have the same meaning or different meanings, the specific meaning of which must be determined by its interpretation in that specific embodiment or further in conjunction with the context of that specific embodiment.

[0083] 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 only to distinguish information of the same type from one another. For example, without departing from the scope of this document, 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 word “if” as used herein may be interpreted as “when…” or “in response to determination”. Furthermore, as used herein, the singular forms “a,” “an,” and “the” are intended to also include the plural forms unless the context indicates otherwise. It should be further understood that the terms “comprising,” “including,” indicate the presence of the stated feature, step, operation, element, component, item, kind, and / or group, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, kinds, and / or groups. The terms “or,” “and / or,” “including at least one of the following,” etc., as used in this application may be interpreted as inclusive, or mean any one or any combination thereof. For example, "including at least one of the following: A, B, C" means "any one of the following: A; B; C; A and B; A and C; B and C; A and B and C." Similarly, "A, B, or C" or "A, B, and / or C" means "any one of the following: A; B; C; A and B; A and C; B and C; A and B and C." Exceptions to this definition only occur when the combination of elements, functions, steps, or operations is inherently mutually exclusive in some way.

[0084] It should be understood that although the steps in the flowcharts of this application's embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some of the steps in the figures may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times, and their execution order is not necessarily sequential, but can be performed alternately or in turn with other steps or at least a portion of the sub-steps or stages of other steps.

[0085] Depending on the context, the words “if” or “suppose” as used here can be interpreted as “when” or “in response to determination” or “in response to detection.” Similarly, depending on the context, the phrases “if determination” or “if detection (of the stated condition or event)” can be interpreted as “when determination” or “in response to determination” or “when detection (of the stated condition or event)” or “in response to detection (of the stated condition or event).”

[0086] It should be noted that step designations such as S10 and S20 are used in this document for the purpose of more clearly and concisely describing the corresponding content, and do not constitute a substantial limitation on the order. In specific implementation, those skilled in the art may execute S20 first and then S10, etc., but these should all be within the protection scope of this application.

[0087] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0088] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.

The image frames processed by the GPU 1041 can be stored in the memory 109 (or other storage medium) or transmitted via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 can receive sound (audio data) in operating modes such as telephone call mode, recording mode, and voice recognition mode, and can process such sound into audio data. The processed audio (voice) data can be converted into a format that can be transmitted to a mobile communication base station via the radio frequency unit 101 in telephone call mode. The microphone 1042 can 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.

As a type of motion sensor, an accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the phone's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. Other sensors that may be configured in the phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

Optionally, user input unit 107 may include touch panel 1071 and other input devices 1072. Touch panel 1071, also known as a touch screen, can collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 1071), and drive corresponding connection devices according to a pre-set program. Touch panel 1071 may include a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends it to processor 110, and can receive and execute commands sent by processor 110.

[0126] Downlink Control Information (DCI) is the information content carried by the PDCCH. It can be sent from network devices to terminal devices through the PDCCH channel and may carry the TCI field.

[0127] In addition, network devices can also receive information from terminal devices. To ensure effective and normal communication between terminal devices and network devices, both 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).

[0128] In LTE scenarios, the energy consumption of network equipment is within a controllable range due to the relatively small number of terminal devices. However, with the popularization of 5G, the number of terminal devices and network demand are increasing, and the energy consumption of network equipment is getting higher and higher, which is not conducive to the sustainable operation of the network.

[0129] To address the aforementioned technical problems, the solutions provided in this application embodiment consider extending the period of the public signal transmitted by the network device. For cells with low communication demand, the transmission function of the network device can even be canceled or the transmission function of some beams can be terminated to reduce the signal transmission volume of the network device and solve the technical problem of high energy consumption of the network device.

[0130] Figure 3 This is an example diagram illustrating an application scenario of a processing method, as shown in one embodiment. Figure 3 As shown, network device TRP301 (Transmission / Reception Point) can correspond to target cell 302, which may include a movable terminal device 303. Network device 301 can send downlink information to terminal device 303. Terminal device 303 can send uplink information to network device 301.

[0131] Figure 4 This is a schematic flowchart illustrating the processing method of the first embodiment of this application. The processing method provided by this application can be applied to network devices (such as base stations), which can be accessed by terminal devices.

[0132] like Figure 4 As shown, the processing method provided in this application may include the following steps:

[0133] S1: In response to the fulfillment of the first preset condition, send the first downlink information and enter the energy-saving state.

[0134] Energy-saving state can refer to a state in which network devices shut down the transmission and reception of service data, but can perform necessary synchronization signal block transmissions, and the transmission period of the synchronization signal block is longer than that of the synchronization signal block in the normal state.

[0135] Optionally, the power-saving state may include at least one of deep sleep, light sleep, and micro sleep. Deep sleep, light sleep, or micro sleep can be a sleep mode of the device. In any one or more of the deep sleep, light sleep, and micro sleep modes, the device may enter a low-power state, that is, enter a power-saving state.

[0136] Optionally, the order of sending the first downlink information in step S1 can be limited, either before entering the energy-saving state or after entering the energy-saving state. Figure 3 The sequence of steps shown is merely exemplary and does not constitute a specific limitation on the order of sending the first downlink information and entering the power-saving state.

[0137] In this embodiment, the network device can send first downlink information and enter a power-saving state when a first preset condition is met. The network device in power-saving state can transmit necessary synchronization signal blocks and / or receive uplink wake-up signals at a specified time to reduce power consumption. Furthermore, by sending the first downlink information to the terminal device, the device is instructed to enter power-saving mode, thereby achieving communication synchronization between the terminal device and the network device, improving energy efficiency, and preventing invalid information transmission from the terminal device to the network device.

[0138] In this embodiment, in addition to entering the energy-saving state in response to meeting the first preset condition, the network device can also return to the normal state in response to meeting the second preset condition. That is, the network device can effectively and quickly switch between the energy-saving state and the normal state through the first preset condition and the second preset condition.

[0139] Optionally, the first preset condition may include at least one of the following:

[0140] The first scenario is that the number of terminal devices residing in all beam directions of the synchronization signal block burst concentration of the target cell is less than the first target threshold.

[0141] Optionally, the number of terminal devices residing in all beam directions of the synchronization signal block burst set in the target cell is less than the first target threshold. This can include the number of terminal devices interacting with the network device on all beams where the synchronization signal block burst set location parameter is set to 1 being less than the first target threshold. The value of the first target threshold can be set according to actual usage needs. For example, the value of the first target threshold can be related to the time period when the terminal device is currently working. For instance, if the terminal device is working during the day or night, the usage demand of the terminal device is higher during the day, so the first target threshold can be set to a larger value; if the usage demand of the terminal device is lower at night, the first target threshold can be set to a smaller value. Optionally, the first target threshold can be preset during network deployment or can be selected autonomously by the network device within an optional range based on factors such as device type.

[0142] In this embodiment, by obtaining the number of terminal devices stationed on all beams, the transmission period of all synchronization signal blocks in the burst concentration of the target cell is increased, thereby reducing the energy consumption of network devices in transmitting synchronization signal blocks and achieving the purpose of energy saving of network devices.

[0143] The second type: 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.

[0144] If the number of data packets to be transmitted 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, this may include situations where only small packet data transmissions are occurring on all beams where the synchronization signal block burst set position parameter is set to 1, or where the interval between two data transmissions is relatively large. In this case, the target cell can notify the terminal equipment to transfer data services to the cell corresponding to a neighboring base station in advance, thereby allowing the target cell to cancel or increase the transmission period of certain synchronization signal blocks.

[0145] In this embodiment, the target cell can cancel or increase the transmission period of certain synchronization signal blocks to reduce the energy consumption of the base station corresponding to the target cell in transmitting synchronization signal blocks, thereby achieving the purpose of energy saving of network equipment.

[0146] The third type: The number of UEs residing in at least one beam direction of the synchronization signal block burst concentration in the target cell is less than the fourth target threshold.

[0147] The fourth target threshold refers to the number of UEs camped in at least one beam direction within the synchronization block burst set of the target cell being less than the fourth target threshold. This primarily means that the number of terminal devices interacting with the network device on at least one beam with the synchronization block burst set location parameter set to 1 is less than the fourth target threshold. The fourth target threshold can be related to the current time period of the terminal's operation, such as whether the terminal is operating during the day or night. The fourth target threshold can be preset during network deployment or can be autonomously selected by the network device within a selectable range based on factors such as device type.

[0148] In this embodiment, by obtaining the number of terminal devices camped on at least one beam, the transmission period of the synchronization signal block in a certain beam direction of the target cell can be increased, thereby reducing the energy consumption of the network device in transmitting the synchronization signal block and achieving the purpose of energy saving of the network device.

[0149] The fourth type: The number of data packets to be sent and / or received in at least one beam direction of the synchronization signal block burst concentration in the target cell is less than the fifth target threshold and / or the data transmission frequency is less than the sixth target threshold.

[0150] In this embodiment, the number of data packets to be transmitted and / or received in at least one beam direction of the synchronization signal block burst set in the target cell can be compared with a fifth target threshold and / or the data transmission frequency can be compared with a sixth target threshold to obtain the size of the transmitted data packets and / or the transmission frequency in at least one beam direction where the synchronization signal block burst set position parameter is set to 1. This effectively adjusts the number of terminal devices in a certain beam direction. Finally, the network device shuts down beam transmission in certain beam directions in the target cell or increases the transmission period of beams in certain beam directions to achieve network energy saving.

[0151] Optionally, this embodiment involves multiple target thresholds. For example, a first target threshold, a second target threshold, etc., can be set according to usage requirements. The descriptions of "first," "second," etc., do not imply a sequential order of the targets, nor do they imply numerical magnitude.

[0152] Optionally, the target cell can be the coverage area of ​​the network device, and the network device communicates with the terminal device within the target cell.

[0153] At least one beam direction in a Synchronization Signal Block (SSB) Burst Set can refer to the transmission and reception direction of one or more synchronization signal blocks whose position parameters are set to 1. In this application, by judging at least one beam direction in a synchronization signal block whose position parameters are set to 1 under a first preset condition, the period of some beams in the SSB Burst Set can be increased or the transmission of some beams in the SSB Burst Set can be canceled, thereby achieving energy saving in network equipment.

[0154] The beam directions in a synchronization signal block burst set can refer to the transmission and reception directions of all synchronization signal blocks in the synchronization signal block with a position parameter set to 1. In this application, by judging all beam directions in the synchronization signal blocks with a position parameter set to 1 under a first preset condition, the period of all beams in the synchronization signal block burst set can be increased simultaneously or the transmission of all beams in the synchronization signal block burst set can be canceled to achieve energy saving of network equipment.

[0155] Optionally, entering an energy-saving state may specifically include at least one of the following:

[0156] The first energy-saving state is that the transmission period of at least one synchronization signal block in the burst concentration of the target cell is increased to the target period, while the transmission period of at least one synchronization signal block in the burst concentration of the target cell remains unchanged.

[0157] By increasing the transmission period of synchronization signal blocks, network devices can reduce the frequency of sending synchronization signal blocks, increase the sleep time of network devices, and thus reduce the power consumption of network devices.

[0158] In this embodiment, by increasing the transmission period of at least one synchronization signal block in the target cell's synchronization signal block burst to the target period, while keeping the transmission period of at least one synchronization signal block unchanged, the transmission period of the synchronization signal blocks in the idle state can be increased first when some synchronization signal blocks are in a busy state and some synchronization signal blocks are in an idle state. This maximizes the energy saving of network equipment without affecting the communication of synchronization signal blocks in the busy state.

[0159] The second energy-saving state: at least one synchronization signal block in the burst concentration of the target cell is canceled from transmission, and the transmission period of at least one synchronization signal block in the burst concentration of the target cell remains unchanged.

[0160] Cancellation of at least one synchronization signal block transmission can refer to the cancellation of transmission of synchronization signal blocks in one or more beam directions within a synchronization signal block burst. By reducing the number of synchronization signal blocks transmitted simultaneously over a period of time, network devices can reduce their energy consumption, thereby achieving energy saving.

[0161] In this embodiment, by canceling the transmission of at least one synchronization signal block in the burst concentration of the target cell and keeping the transmission period of at least one synchronization signal block in the burst concentration of the target cell unchanged, it is possible to reduce the number of synchronization signal blocks that are idle for a period of time when some synchronization signal blocks are in a busy state and some synchronization signal blocks are in an idle state, thereby achieving energy saving of network equipment.

[0162] The third energy-saving state: all synchronization signal blocks in the target cell's burst-concentration are cancelled.

[0163] Cancel transmission of all synchronization signal blocks can mean that all synchronization signal blocks with the burst set position parameter set to 1 in the synchronization signal block are canceled to minimize the power consumption of network devices.

[0164] In this embodiment, by canceling the transmission of all synchronization signal blocks in the burst concentration of the target cell, the base station corresponding to the target cell can be completely shut down or deactivated, thereby achieving energy saving of network equipment.

[0165] The fourth energy-saving state: The transmission period of all synchronization signal blocks in the burst concentration of the target cell is increased to the target period.

[0166] Increasing the period of all synchronization signal blocks means simultaneously increasing the transmission period of all synchronization signal blocks whose burst set position parameter is set to 1. Increasing the period of synchronization signal blocks can reduce the frequency at which network devices transmit synchronization signal blocks, effectively reducing the power consumption of network devices.

[0167] In this embodiment, by increasing the transmission period of all synchronization signal blocks in the burst concentration of the target cell to the target period, the frequency of network devices sending synchronization signal blocks can be reduced, and the sleep time of network devices can be increased, thereby reducing the energy consumption of network devices.

[0168] Optionally, the first downlink information can indicate that the terminal device has entered a power-saving state, and the specific implementation method of the network device entering the power-saving state. Optionally, the network device can use the first downlink information to 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, and the specific index of the synchronization signal block whose period is increased or whose transmission is canceled, so as to achieve matching of the power-saving state operation of the network device and the terminal device.

[0169] refer to Figure 4 The network device can send the first downlink information to the terminal device in the target cell.

[0170] Optionally, the first downlink information may include downlink control information (DCI).

[0171] Optionally, the first downlink information may include at least one of the following:

[0172] An energy indication field used to indicate the energy consumption status of a target cell;

[0173] A period field used to indicate the transmission period of at least one synchronization signal block of the target cell;

[0174] Synchronization signal block index field used to indicate the synchronization signal block index of the target cell.

[0175] In this embodiment, by sending first downlink information to the terminal device in the target cell, the network device can enable the terminal device to transfer all or at least one synchronization signal block direction of service transmission to the cell corresponding to the neighboring base station or other synchronization signal block direction in advance, so as to better match the current energy-saving status processing of the target cell and thus better realize the energy saving of the network device.

[0176] like Figure 5 The diagram shown is a flowchart illustrating the processing method of the second embodiment of this application, which can be applied to a terminal device. The method may include:

[0177] Step S10: Receive downlink information.

[0178] Step S20: Obtain the actual transmission period of at least one synchronization signal block in the burst set of synchronization signal blocks based on the downlink information.

[0179] Optionally, the downlink information in step S10 of this embodiment may include first downlink information.

[0180] refer to Figure 4 After the network device sends the first downlink information, the terminal device performs step S10, which may specifically include step S101: receiving the first downlink information, and step S20, which may specifically include step S201: obtaining the actual transmission period of at least one synchronization signal block in the synchronization signal block burst set according to the first downlink information.

[0181] Optionally, the downlink information in step S10 may also include second downlink information.

[0182] Optionally, the second downlink information may include at least one of the following:

[0183] An energy indication field used to indicate the energy consumption status of a target cell;

[0184] A period field used to indicate the transmission period of at least one synchronization signal block of the target cell;

[0185] Synchronization signal block index field used to indicate the synchronization signal block index of the target cell.

[0186] Alternatively, the second downlink information may also be conventional downlink control information that does not include any of the energy indication field, periodic field, or synchronization signal block index field.

[0187] Optionally, the terminal device can quickly obtain the actual transmission cycle of each synchronization signal block through the first or second downlink information, thereby enabling the terminal device to quickly match the specific processing of the network device's energy-saving status and better achieve the energy-saving purpose of the network device.

[0188] Optionally, the terminal device can obtain the index of the synchronization signal block whose period needs to be adjusted due to the burst concentration of synchronization signal blocks and the direction of the synchronization signal block period adjustment based on the first downlink information. For example, it can determine the adjustment direction such as increasing the synchronization signal block period or directly canceling the transmission of this synchronization signal block based on the first downlink information.

[0189] Optionally, the terminal device can also restore the transmission period of at least one synchronization signal block in the synchronization signal block burst set based on the second downlink information, so as to alleviate the scenario where the terminal device has poor transmission quality on some beams or the service cannot be transmitted normally in some cells.

[0190] In this embodiment, after the network device sends downlink information, the terminal device can receive the downlink information sent by the network device. The downlink information can control the actual transmission period of at least one synchronization block in the synchronization block burst concentration, so as to reduce the amount of synchronization blocks transmitted by the network device within a certain period of time by increasing the transmission period of the synchronization block or canceling the transmission of the synchronization block, thereby reducing the power consumption of the network device.

[0191] Optionally, step S20: Obtaining the actual transmission period of at least one synchronization signal block in the synchronization signal block burst set based on the downlink information, which may include at least one of the following:

[0192] The actual transmission period of all synchronization signal blocks in the synchronization signal block burst set is obtained based on the energy indication field and the period field.

[0193] The actual transmission period of at least one synchronization signal block in the synchronization signal block burst set is obtained based on the energy indication field, the period field, and the synchronization signal block index field.

[0194] The actual transmission period of at least one synchronization block in the synchronization block burst set is obtained based on the energy indicator field and the synchronization signal block index field.

[0195] 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: determining whether the network device is currently in energy-saving or 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 subsequent energy-saving or normal states based on the period field. The adjustment of the transmission period in this scheme can be applied to all synchronization signal blocks whose position parameters in the synchronization signal block burst set are set to 1.

[0196] Optionally, obtaining the actual transmission period of at least one synchronization block in the synchronization block burst set based on the energy indication field, period field, and synchronization block index field can be included in all beams set to 1 in the synchronization block burst set. When there may be some beams that do not have data transmission or only a few terminals are transmitting data, the transmission period of these relatively idle beams can be increased to minimize the energy consumption of network equipment.

[0197] Optionally, obtaining the actual transmission period of at least one synchronization block in the synchronization block burst set based on the energy indication field and the synchronization block index field can be included in all beams set to 1 in the synchronization block burst set, canceling the transmission period of some relatively idle beams to achieve energy saving for network devices. Compared to increasing the transmission period of relatively idle beams, this scheme can better reduce the energy consumption of network devices and can reduce the number of bits of downlink control information transmitted by network devices.

[0198] In this embodiment, the actual transmission period of all synchronization signal blocks in the synchronization signal block burst set can be obtained based on the energy indication field and the period field in the downlink information.

[0199] Optionally, the downlink information may include first downlink information or second downlink information.

[0200] Optionally, the first downlink information may include at least one of the following:

[0201] An energy indication field used to indicate the energy consumption status of a target cell;

[0202] A period field used to indicate the transmission period of at least one synchronization signal block of the target cell;

[0203] Synchronization signal block index field used to indicate the synchronization signal block index of the target cell.

[0204] In this embodiment, the first downlink information is used to explain how to use at least one of the energy index field, period field, and synchronization signal block index field of the first downlink information to constrain the transmission period of at least one synchronization signal block in the burst set of synchronization signal blocks, so as to realize the matching processing of transmission and reception of network devices and terminal devices in energy-saving state, and better realize the energy saving of network devices.

[0205] 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 normal state; if the energy indication field is set to "1", it indicates that the current target cell is in energy-saving state.

[0206] Optionally, the Period field in the first downlink information can occupy three bits. Different combinations of bit values ​​can represent different synchronization signal block transmission periods. For example, 000 can represent a period of 5ms, 001 can represent a period of 10ms, 010 can represent a period of 20ms, 011 can represent a period of 40ms, 100 can represent a period of 80ms, and 101 can represent a period of 160ms.

[0207] Optionally, different combinations of bit values ​​can also indicate that the transmission period of the synchronization signal block in the power-saving state is a multiple of the transmission period of the synchronization signal block currently configured by the higher layer. For example, 000 can indicate that the transmission period of the synchronization signal block in the power-saving state is 1 time that of the synchronization signal block currently configured by the higher layer, 001 can indicate that the transmission period of the synchronization signal block in the power-saving state is 2 times that of the synchronization signal block currently configured by the higher layer, 010 can indicate that the transmission period of the synchronization signal block in the power-saving state is 4 times that of the synchronization signal block currently configured by the higher layer, 011 can indicate that the transmission period of the synchronization signal block in the power-saving state is 8 times that of the synchronization signal block currently configured by the higher layer, and so on.

[0208] Of course, the bit length of the above-mentioned period and the specific period duration corresponding to the bit value method can be set according to the usage requirements. The above is merely an example and should not constitute a specific limitation on the technical solution of this application.

[0209] Optionally, the energy consumption status of the target cell can include an energy-saving status and a normal status. In the energy-saving status, the base station can effectively reduce the number of synchronization signal block transmissions to reduce energy consumption. In the normal status, the base station maintains the normal number of synchronization signal block transmissions and service processes, and the network energy consumption is normal.

[0210] Optionally, in this technical solution, a Synchronization Signal Block Burst set (SSB burst set) may include up to 64 candidate Synchronization Signal Block (SSB) positions. Taking an SSB Burst set containing 8 candidate SSBs as an example, the higher-layer parameter Synchronization Signal Block Burst Set Position Parameter (ssb-PositionsInBurst) may contain 8 bits, each bit representing a candidate SSB. Each candidate SSB may include an SSB identifier, which can be represented by a position number. For example, the first position parameter could be SSB#1, the second position parameter could be SSB#2, and so on. For instance, 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, namely SSB#2, SSB#3, SSB#5, and SSB#7.

[0211] Optionally, all candidate synchronization blocks in a synchronization block burst set can be sent within 5ms (millisecond).

[0212] Optionally, the transmission of all the synchronization signal blocks in the synchronization signal block burst set can be cancelled according to the energy indication field.

[0213] 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', 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 indicates that the base station has entered the energy-saving state and no longer performs any synchronization signal block transmission.

[0214] Optionally, the actual transmission period of all the synchronization signal blocks in the synchronization signal block burst set can be obtained according to the energy indication field and the period field.

[0215] 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', 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:

[0216] Table 1

[0217] SSB#1 SSB#2 SSB#3 SSB#4 SSB#5 SSB#6 SSB#7 SSB#8

[0218] 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 indication field (energyindicator) 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 indication field and the period field, the terminal device will learn that the current base station has entered 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.

[0219] For ease of understanding, Figure 6A schematic diagram illustrating the increasing transmission period of a synchronization signal block is provided. In the diagram, the horizontal axis represents time, and the vertical axis represents the resource block size of the frequency domain resources occupied by the synchronization signal block. In the diagram, 601 represents the transmission period interval of the synchronization signal block when the base station is in normal operation, where the interval is 20ms; 602 represents the transmission period interval of the synchronization signal block when the base station is in power-saving mode, where the interval increases from 20ms to 80ms. Based on... Figure 6 As shown, a base station in normal operation needs to send four synchronization signal blocks in 80ms, while in energy-saving mode, it only needs to send one synchronization signal block in 80ms. This means that in energy-saving mode, the base station can reduce the number of synchronization signal blocks sent per unit time by increasing the transmission period of the synchronization signal blocks, thereby reducing network equipment power consumption and achieving network energy saving.

[0220] Optionally, the base station can also be as follows: Figure 7 The transmission of a synchronization signal block is directly cancelled as shown. Figure 7 The 701 indicates that when the base station is in normal operation, the transmission period of the synchronization signal block is 20ms. Figure 7 The 702 indicates that the base station enters power-saving mode when the first preset condition is met, at which point the transmission of synchronization signal blocks is directly cancelled. That is, the base station... Figure 7 In the energy-saving state shown in 702, the transmission of the synchronization signal block is directly cancelled to reduce the power consumption of network equipment.

[0221] Optionally, the network device may also simultaneously increase the transmission period of all synchronization blocks in a synchronization block burst set or cancel the transmission of all synchronization blocks in a synchronization block burst set, and notify the terminal device of its specific synchronization block transmission processing operation in energy-saving state through the energy indication field and period field in the first downlink information.

[0222] Optionally, the first downlink information may also include a synchronization signal block index field, and the number of first bits occupied by the synchronization signal block index field may be equal to the number of second bits where the synchronization signal block burst set position parameter is set to 1.

[0223] Optionally, if the number of bits set to 1 in the synchronization signal block burst set position parameter is 4, then the number of bits occupied by the newly added synchronization signal block index field in the first downlink information is also 4.

[0224] In this embodiment, by setting the number of first bits occupied by the synchronization signal block index field to the number of second bits of the synchronization signal block burst set position parameter to 1, compared to setting the number of first 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 synchronization signal blocks in energy-saving state can still be achieved.

[0225] Optionally, the SSB burst set position parameter refers to a higher layer parameter

[0226] ssb-PositionsInBurst, and only the beam transmission directions corresponding to the SSBs with the set bits in ssb-PositionsInBurst are used by the terminal for data reception and transmission.

[0227] Optionally, the actual transmission period of at least one SSB in the SSB burst set can be obtained according to the energy indication field and the SSB index field.

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

[0229] Optionally, each bit of the SSB index field can respectively represent the transmission status of the SSBs with the set bits in the SSB burst set position parameter.

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

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

[0232] For ease of understanding, let's take the example of SSB-PositionsInBurst being set to '01101010'. This means that only the beam directions corresponding to SSB#2, SSB#3, SSB#5, and SSB#7 out of the eight candidate synchronization signal blocks are used for data transmission between the terminal and network devices. Since the number of bits occupied by the first bit of the synchronization signal block index field is equal to the number of bits of the second bit when the synchronization signal block burst set position parameter is set to 1, the synchronization signal index block occupies 4 bits. Its first bit refers to SSB#2 in the synchronization signal block burst set, the second bit refers to SSB#3, the third bit refers to SSB#5, and the fourth bit refers to SSB#7. The bit values ​​of the synchronization signal index block can control the transmission of the corresponding synchronization signal block in the synchronization signal block burst set position set parameter it refers to. For example, if a bit is set to 1, the corresponding synchronization signal block is canceled from transmission; if a bit is set to 0, the corresponding synchronization signal block maintains normal periodic transmission. For example, if the synchronization signal block index field "SS / PBCHindex" 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 will be canceled from transmission, while the synchronization signal blocks corresponding to SSB#2 and SSB#5 will maintain normal periodic transmission.

[0233] Optionally, the actual transmission period of at least one synchronization block in the synchronization block burst set can be obtained based on 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 refer to the transmission status of a signal block with its position parameter set to 1 within the synchronization signal block burst set.

[0235] Optionally, if the target bit of the synchronization signal block index field is set to 1, the transmission period of the corresponding synchronization signal block in the synchronization signal block burst set location 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 is 0, the synchronization signal block corresponding to the synchronization signal block burst set position parameter it refers to will continue to be transmitted normally in the original period.

[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 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 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 position of the synchronization signal index block can be used to control the transmission of 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 an SSB transmission period of 80 ms, and the high - level parameter ssb - periodicityServingCell is set to '20 ms', then 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 each time, multiple candidate positions in the synchronization signal block burst set for a single transmission can be dispersed to multiple transmission periods, thereby increasing the transmission period of the synchronization signal block, reducing the energy of the synchronization signal block transmitted by the base station each time, and achieving energy saving for the network device. For example, it can be set that the number of SSBs that can be transmitted fixedly in each transmission period is N1, and the number of actually transmitted SSBs obtained according to the number of 1s in the synchronization signal block burst set position parameter is N2. Then, the number of SSBs that can be transmitted at each SSB period transmission position is set to a value less than or equal to the minimum value of N1 and N2.

[0239] If ssb-PositionsInBurst is set to '01111110', then the number N2 of SSBs actually transmitted out of the 8 candidate SSBs can be 6. Assuming the fixed number of SSBs that can be sent in each transmission cycle, N1, can be 4, then the number of SSBs that can be sent in each SSB cycle, N = min(N1, N2), can be 4, meaning the candidate positions in the SSB set for a single transmission are 4. Therefore, the 6 SSBs actually transmitted out of the 8 candidate SSBs will be fully transmitted in ceil(N2 / N) cycles, meaning the 6 actual SSBs need to 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, such as Figure 8 The example index settings shown can be configured as follows: ssb-PositionsInBurst can be set to '01111110', and ssb-periodicityServingCell can be set to 20ms. Therefore, the SSB transmission period is 20ms, and the actual number of SSBs transmitted, N2, is, for example, 6. If we assume that the fixed number of SSBs that can be sent per transmission period, N1, is, for example, 4, then the maximum number of SSBs transmitted per SSB period is N = min(N1, N2), where N can be 4. Optionally, it can be configured as follows: Figure 9 The example diagram showing the index settings illustrates that the first four synchronization signal blocks (SSBs) can be transmitted initially: SSB#2, SSB#3, SSB#4, and SSB#5. The remaining synchronization signal blocks (SSBs#6 and SSB#7) can be transmitted in the second transmission. By limiting the number of SBBs transmitted each time, the transmission period of the synchronization signal blocks in the burst set location parameters can be increased without changing the downlink control information bearer bits. This reduces the energy consumption of the base station each time it transmits a synchronization signal block, thus achieving energy saving for network equipment.

[0241] Alternatively, by increasing the transmission period of the synchronization signal block by limiting the number of SSBs transmitted each time, it is possible to save network energy without increasing the bearer bits in the downlink control information.

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

[0243] As can be seen from the above embodiments, when a network device enters an energy-saving state, the energy required for the base station to transmit synchronization blocks can be reduced by canceling the transmission of all synchronization blocks in the synchronization block burst set, increasing the transmission period of all synchronization blocks in the synchronization block burst set, increasing the transmission period of at least one synchronization block in the synchronization block burst set, canceling the transmission of at least one synchronization block in the synchronization block burst set, or limiting the number of synchronization blocks in the synchronization block burst set transmitted in each transmission. 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 block transmission processing method of the base station in the energy-saving state, so as to better match the service transmission in the network's energy-saving state. However, because the number of terminals or services that a base station can handle is limited, when there is a sudden increase in service volume or a significant increase in the number of terminals within the base station's deployment range, the base station serving these terminals cannot remain in the energy-saving state indefinitely; that is, the base station needs to switch to normal operating mode.

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

[0245] like Figure 10 The diagram shown is a flowchart illustrating the processing method of the third embodiment of this application.

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

[0247] In this embodiment, the terminal device initiates a switch to the network device by sending an uplink wake-up signal, thereby achieving a power consumption state switch based on the usage needs of the terminal device and realizing a fast and effective switch of power consumption states.

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

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

[0250] The cumulative number of events in which the terminal device reaches the maximum number of preamble transmissions in the current serving cell exceeds the ninth target threshold.

[0251] Optionally, the currently serving cell can be a cell that can also be covered by a base station in energy-saving mode.

[0252] The reference signal receiving power (RSR) of a terminal device in the synchronization signal / physical broadcast channel block of the current serving cell represents a key parameter of wireless signal strength in LTE or 5G networks and is a requirement for physical layer measurements. If the RRS is too low, it indicates that the current serving base station is too far from the terminal device, resulting in a higher data packet error rate, and the terminal device needs to switch to a closer serving base station.

[0253] The event that the number of preamble transmissions reaches the maximum number of transmissions can refer to the number of times the preamble is sent exceeds the maximum number of transmissions configured by higher layers. This scenario usually occurs when there are too many terminal devices connected to the current serving base station, causing the base station to be overloaded. The terminal devices need to initiate random access to other nearby serving base stations to ensure the normal transmission of service data.

[0254] In this embodiment, the terminal device can initiate an uplink wake-up signal to the network device when the reference signal received 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 cumulative number of events in which it transmits preamble in the current serving cell reaches the maximum number of transmissions exceeds 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, thereby restoring normal service transmission functions.

[0255] It should be noted that this technical solution involves multiple thresholds, such as a first target threshold and a second target threshold. Different thresholds are used to make numerical judgments on different parameters and can be determined according to the judgment requirements of each parameter. By setting the thresholds for each parameter, the results of different parameters can be affected accordingly, thereby improving the accuracy of threshold judgment.

[0256] In some embodiments, reference Figure 10 After the terminal device executes step S30, the network device can execute step S2: receive the uplink wake-up signal.

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

[0258] Terminal identifier;

[0259] Specific synchronization signal block index;

[0260] A specific synchronization signal block period;

[0261] preamble sequence;

[0262] Track the reference signal sequence;

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

[0264] Optionally, the uplink wake-up signal can be a periodic signal, that is, it is sent at fixed periodic positions.

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

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

[0267] Optionally, the base station can determine the number of UEs camped in at least one beam direction of the synchronization signal block burst concentration in the target cell by 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 devices in the cell served by the base station, and achieves a better balance between energy saving and service transmission based on the usage demand of the terminal devices in the cell served by the base station, thereby improving the accuracy and efficiency of the network device's energy consumption control.

[0269] refer to Figure 10 The network device can also execute step S3: in response to the fulfillment of the second preset condition, send second downlink information and enter normal state. The second downlink information can be sent by the network device to the terminal device.

[0270] In this embodiment, after the network device switches to energy-saving mode, it can enter normal mode under the second preset condition.

[0271] Optionally, Figure 11 Example diagram of the transition to the normal state, such as Figure 11 As shown, terminal device 1102 can send an uplink wake-up signal (WUS) to network device 1101.

[0272] Network device 1101 can switch from energy-saving state to normal state according to the second preset conditions, and at the same time send the second downlink information to terminal device 1102.

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

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

[0275] Network devices can determine the number of UEs that will be camped in a specific beam direction based on the number of terminal IDs in the uplink wake-up signals received on that beam. If the number of UEs camped on all beams in the synchronization signal block burst is greater than or equal to the first target threshold, the network device can switch from power-saving mode to normal mode.

[0276] Optionally, the number of terminal devices residing in all beam directions is greater than or equal to the first target threshold. This 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 being greater than or equal to the first target threshold, or the number of terminal devices residing in each beam direction being greater than or equal to the first target threshold.

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

[0278] The second condition for 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 burst concentration of the synchronization signal block 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 prepared to send. Optionally, the number of data packets that the terminal device is prepared 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] Data transmission frequency can refer to the number of data packets received and / or sent per unit of time. A unit of time can be one time slot, one subframe, one radio frame, or other counting units.

[0281] In this embodiment, the network device can make threshold judgments based on the number of data packets received and / or sent in all beam directions and / or the frequency of data transmission, thereby enabling the detection and judgment of data transmission needs in all beam directions. By utilizing data transmission needs, the network device can achieve accurate device control, and the control efficiency and accuracy can also be improved.

[0282] The third condition that satisfies the second preset condition may include: the number of UEs camped in at least one beam direction of the synchronization signal block burst concentration 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 can better reduce the energy required for the base station to transmit synchronization signal blocks by using a threshold to determine the number of UEs residing in a certain beam direction and controlling the granularity of the synchronization signal blocks transmitted by the base station within a beam range, thereby achieving energy saving for the network device.

[0285] The fourth condition that satisfies the second preset condition may include: the number of data packets to be sent and / or received in at least one beam direction of the synchronization signal block burst concentration 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" refers to the beam directions corresponding to all synchronization signal blocks whose position parameters are set to 1 in the synchronization signal block burst set. The processing of synchronization signal blocks for all beam directions is performed on a unit basis: a synchronization signal block burst set.

[0287] Optionally, at least one beam direction refers to the beam direction corresponding to one or more synchronization signal blocks whose position parameters are set to 1 in the synchronization signal block burst set. The processing of synchronization signal blocks with at least one beam direction is performed on a unit basis, that is, one beam in the synchronization signal block burst set.

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

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

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

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

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

[0293] In this embodiment, the transmission period of at least one synchronization signal block of the target cell is consistent with the period configured for the period parameter of the synchronization signal block of the serving cell, and / or the transmission period of all synchronization signal blocks with bits set to 1 in the burst set location parameter of the target cell is consistent with the period configured for the period parameter of the synchronization signal block of the serving cell. By adjusting the transmission period and / or the burst set location parameter settings, the period adjustment of the network device is realized, 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] In carrier aggregation, the secondary cell whose TA value belongs to the same time advance group as the primary cell;

[0296] In carrier aggregation, the auxiliary cell is the micro base station whose distance to the macro base station corresponding to the primary cell is less than the seventh target threshold.

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

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

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

[0300] Alternatively, carrier aggregation (CA) refers to combining two or more component carriers (CC) together to support greater transmission bandwidth.

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

[0302] The target cell can be a secondary cell in carrier aggregation whose TA value belongs to the same time advance group as the primary cell. The target cell in carrier aggregation can be a secondary cell whose TA value belongs to the same time advance group as the primary cell.

[0303] Optionally, base stations can be classified into macro base stations, micro base stations, etc., according to their coverage area / transmission power.

[0304] The target cell can be the auxiliary cell corresponding to the micro base station in carrier aggregation whose distance from the macro base station corresponding to the main cell is less than the seventh target threshold.

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

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

[0307] In this embodiment, after the target cell is determined, it can be determined whether the base station corresponding to the target cell is in an energy-saving state according to the first preset condition. If the base station corresponding to the target cell is in an energy-saving state, the services of the terminal served by the target cell can be switched to the serving cell corresponding to other nearby base stations, thereby reducing the energy consumption of the base station serving the target cell. Optionally, a secondary cell in carrier aggregation whose TA value belongs to the same time advance group as the primary cell 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 the matching of the energy-saving state of the network device and the terminal's transmission or reception processing.

[0308] refer to Figure 10 In step S3, after the network device sends the second downlink information, the terminal device executes step S10: receiving downlink information, which may specifically include step S102: receiving the second downlink information.

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

[0310] In this embodiment, the terminal device can determine the energy consumption status of the network device based on 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 used to indicate the energy consumption status of a target cell;

[0313] A period field used to indicate the transmission period of at least one synchronization signal block of the target cell;

[0314] Synchronization signal block index field 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 and the specific processing operation of the synchronization signal block in the normal state of the network device, so as to better transmit data services with the network device.

[0316] Alternatively, the second downlink information can also be traditional physical downlink control information that does not include the energy indication field, periodic field, or synchronization signal block index field.

[0317] Optionally, 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] Optionally, 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] Optionally, 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 high-layer parameters ssb-PositionsInBurst and the high-layer parameter

[0320] ssb-periodicityServingCell in the next SSB period. For example, if the carrier frequency f satisfies: 3 GHz < f <= 6 GHz, then an SSB Burst set contains 8 candidate SSBs, the high-layer parameter ssb-PositionsInBurst is set to '01101010', and the high-layer parameter

[0321] 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 period of 20 ms.

[0322] Optionally, 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.

[0323] Optionally, if the received second downlink information by the terminal device does not include an energy indication (energyindicator) 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 high-layer parameters ssb-PositionsInBurst and the high-layer parameter

[0324] ssb-periodicityServingCell.

[0325] Optionally, 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.

[0326] Optionally, if the second downlink information received by the terminal device includes both an energy indicator field and a synchronization signal block index field, then if the energy indicator 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 restore the transmission of certain beam directions corresponding to certain synchronization signal blocks. For example, suppose the carrier frequency f satisfies: greater than the first frequency and less than or equal to the second frequency, and the higher layer parameter ssb-PositionsInBurst is set to '01101010', and the higher layer parameter...

[0327] Set ssb-periodicityServingCell to 20ms.

[0328] Optionally, under the first preset condition, 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'.

[0329] However, under the second preset condition, the base station corresponding to the target cell enters normal state and the energy indicator 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 normal state, only the normal transmission of SSB#5 and SSB#7 is restored, and SSB#3 is still canceled.

[0330] 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, the period field, and the synchronization signal block index field, and then obtain the actual transmission period of the synchronization signal block in the burst concentration of the synchronization signal block.

[0331] Optionally, if the second downlink information received by the terminal device includes both an energy indicator field and a synchronization block index field, then if the energy indicator field is set to '1' but the synchronization block index is different from the synchronization block index of the first downlink information, the terminal can know that although the base station is in a normal state, it only needs to restore the transmission of certain beam directions corresponding to synchronization blocks. For example, suppose the carrier frequency f satisfies: greater than the first frequency and less than or equal to the second frequency, and the higher layer parameters...

[0332] ssb-PositionsInBurst set to '01101010', high-level parameters

[0333] Set ssb-periodicityServingCell to 20ms.

[0334] Optionally, if the base station corresponding to the target cell enters an energy-saving state under the first preset condition, and the energy indication field in the first downlink information is set to '1', the synchronization signal block index is set to...

[0335] '0111', the period field is set to 80ms.

[0336] However, under the second preset condition, the base station corresponding to the target cell enters the normal state, and the energy indicator 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 and second downlink information, it can be seen that in the energy-saving state, the transmission period of synchronization signal blocks SSB#3, SSB#5, and SSB#7 of the terminal device increases from 20ms to 80ms; in the normal state, the terminal device only restores the period of SSB#5 and SSB#7 from 80ms to 20ms, while SSB#3 still maintains the energy-saving transmission of 80ms.

[0337] Optionally, the CRC scrambling RNTI value of the first downlink information or the second downlink information can be different from the existing RNTI (Radio Network Temporary Identifier) ​​value. For example, the RNTI of the first downlink information or the second downlink information can be defined as SSB-RNTI and its value can be any one of FFF3-FFFB. Optionally, FFF3 and FFFB are both values ​​represented in hexadecimal.

[0338] Optionally, the Cyclic Redundancy Check (CRC) scrambled RNTI value of at least one of the first downlink information or the second downlink information can also be an RNTI (Radio Network Temporary Identifier) ​​value with the same value as SI-RNTI (System Information Radio Network Temporary Identifier) ​​or P-RNTI (Paging Radio Network Temporary Identifier).

[0339] Optionally, the first downlink information or the second downlink information can be an existing downlink control information format (DCI format), for example, the first downlink information or the second downlink information can be DCI format 1_0, etc.

[0340] Optionally, if the first downlink information or the second downlink information is DCI format 1_0 and uses System Information Radio-Network Temporary Identifier (SI-RNTI) for CRC scrambling, then the power indicator field, period field, and synchronization signal block index field in the downlink information can occupy the reserved bits in DCI format 1_0.

[0341] Optionally, if the first or second downlink information is DCI format 1_0 and CRC scrambling is performed using P-RNTI, the power indicator field, period field, and synchronization signal block index field in the downlink information can be bit-occupied according to the following scenarios:

[0342] If the Short Message Indicator field in DCI format 1_0 is set to '10' or '11', the Energy Indicator field, Period field, and Synchronization Signal Block Index field use reserved bits in the Short Message or other reserved bits in DCI format 1_0.

[0343] If the Short Message Indicator field in DCI format 1_0 is set to '01', the Energy Indicator field, Period field, and Synchronization Signal Block Index field use 8 bits from the Short Message and other reserved bits in DCI format 1_0.

[0344] Optionally, the search space set for the first or second downlink information can be the same common search space set (CSS) as SI-RNTI, such as Type0-PDCCH CSS set, Type0A-PDCCH CSS set, etc.

[0345] Optionally, the search space set for the first or second downlink information can be the same common search space set as P-RNTI, such as the Type2-PDCCH CSS set.

[0346] Optionally, the search space set for the first or second downlink information can be the common search space set corresponding to the newly defined RNTI value SSB-RNTI, such as the Type2A-PDCCH CSS set or the Type3-PDCCH CSS set.

[0347] like Figure 12 The diagram shown is a structural schematic of one embodiment of a processing apparatus provided in this application. The processing apparatus may include:

[0348] First response unit 1201: Used to send first downlink information and enter energy-saving state in response to the fulfillment of the first preset condition.

[0349] As one embodiment, the first response unit may include at least one of the following:
