[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202411177606.2, filed on August 26, 2024, entitled "Method, Terminal, Network Side Device and Storage Medium for Information Transmission", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of communication technology, specifically relating to an information transmission method, terminal, network-side device, and storage medium. Background Technology

[0004] In the field of communications, network-side devices can obtain terminal information through information exchange with the terminal, thereby facilitating the acquisition of auxiliary information, optimizing network performance, and improving service experience.

[0005] For example, when a terminal transitions from a disconnected state to a connected state, the network-side device can obtain random access reports from the terminal. The terminal reports the random access report list to the network-side device via ra-ReportList in the UEInformationResponse message. After obtaining the random access report list, the network-side device can obtain the CDF (Cumulative Distribution Function) curve of the random access probability and / or the CDF curve of the random access delay.

[0006] With the development of communication services, the auxiliary information exchanged between terminals and network-side equipment in existing technologies can no longer adequately meet the needs of communication services. For example, network-side equipment may shut down at least one beam in a cell for energy-saving reasons, which will greatly reduce the accuracy of predicting the distribution of terminals in the cell, thereby affecting the overall communication network performance and user experience.

[0100] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art are within the scope of protection of this application.

[0103] It is worth noting that the technologies described in this application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), or other systems. The terms "system" and "network" in this application are often used interchangeably, and the described technologies can be used in the systems and radio technologies mentioned above, as well as in other systems and radio technologies. The following description describes New Radio (NR) systems for illustrative purposes, and the term NR is used in most of the following description; however, these technologies can also be applied to systems other than NR systems, such as 6th Generation (6G) communication systems.

[0104] Figure 1 shows a block diagram of a wireless communication system applicable to an embodiment of this application. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 can be a mobile phone, tablet computer, laptop computer, notebook computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), augmented reality (AR), virtual reality (VR) device, robot, wearable device, flight vehicle, vehicle user equipment (VUE), shipboard equipment, pedestrian user equipment (PUE), smart home (home devices with wireless communication capabilities, such as refrigerators, televisions, washing machines, or furniture), game console, personal computer (PC), ATM, or self-service machine, etc. Wearable devices include: smartwatches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart chains, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, etc. Among these, in-vehicle devices can also be referred to as in-vehicle terminals, in-vehicle controllers, in-vehicle modules, in-vehicle components, in-vehicle chips, or in-vehicle units, etc. It should be noted that the specific type of terminal 11 is not limited in this application embodiment. Network-side equipment 12 may include access network equipment or core network equipment, wherein access network equipment may also be referred to as Radio Access Network (RAN) equipment, radio access network function, or radio access network unit. Access network equipment may include base stations, Wireless Local Area Network (WLAN) access points (AS), or Wireless Fidelity (WiFi) nodes, etc.In this context, a base station may be referred to as a Node B (NB), Evolved Node B (eNB), Next Generation Node B (gNB), New Radio Node B (NR Node B), Access Point, Relay Base Station (RBS), Serving Base Station (SBS), Base Transceiver Station (BTS), Radio Base Station, Radio Transceiver, Basic Service Set (BSS), Extended Service Set (ESS), Home Node B (HNB), Home Evolved Node B, Transmit / Receive Point (TRP), or any other suitable term in the relevant field, as long as the same technical effect is achieved. The term "base station" is not limited to specific technical terms. It should be noted that this application embodiment only uses a base station in an NR system as an example for description and does not limit the specific type of base station. In this application embodiment, the beam may be spatial filtering or Synchronization Signal / Physical Broadcast Channel Block (PBCH). The beams associated with the block (SSB) or the channel state information reference signal (CSI-RS) are described in this application using the SSB of the NR system as an example, without limiting the specific type of beam.

[0105] Figure 2 illustrates an application scenario of information transmission provided in this application embodiment. As shown in Figure 2(a), the terminal has successfully camped on cell 2. For energy saving purposes, the network-side equipment corresponding to cell 1 has turned off SSB1. When the terminal moves to the coverage area of ​​SSB1 in cell 1, the terminal cannot successfully camp on a suitable cell because SSB1 in cell 1 is turned off. At this time, the wireless channel quality measured by the terminal in all cells cannot meet the preset criteria (e.g., the S criterion). Therefore, there may also be problems with parsing system messages and / or parsing paging messages. As shown in Figure 2(b), the terminal has successfully camped on cell 1. For energy saving purposes, the network-side equipment corresponding to cell 1 has turned off SSB2. When the terminal moves to the coverage area of ​​SSB2 in cell 1, the wireless channel quality of cell 1 cannot meet the preset criteria (e.g., the S criterion) because SSB2 in cell 1 is turned off. This causes the terminal to be unable to camp on a suitable cell. Similarly, there may also be problems with parsing system messages and / or parsing paging messages. As shown in Figure 2(c), the terminal has successfully camped in cell 1. When the terminal moves to the coverage area of ​​SSB2, it can listen for paging and system messages in SSB2. When the terminal continues to move to the coverage area of ​​SSB3, the radio channel quality of SSB2 deteriorates, and there are no other cells nearby whose radio channel volume meets the preset criteria (such as the S criterion). If the terminal has an uplink service transmission requirement, it will not be able to successfully complete the random access procedure, which will lead to random access failure and service initiation failure.

[0106] In related technologies, when a terminal moves to an energy-saving cell, it can send a WUS (wakeup signal) to the network-side device, thereby enabling the network-side device to switch the energy-saving cell from energy-saving state to normal state. For example, in Figure 2(a) above, the terminal can send a WUS to the network-side device to reopen the closed SSB, so that it can camp on the corresponding cell through an SSB that meets the preset quality threshold and perform normal services.

[0107] In related technologies, the auxiliary information exchanged between the terminal and the network-side equipment cannot record which SSBs the network-side equipment reactivated to enable the terminal to successfully camp or access the network. This leads to a significant reduction in the accuracy of predicting the distribution of terminals within the cell. If the distribution of terminals under the coverage of an SSB cannot be accurately predicted, for example, if there are terminals under a certain SSB but the prediction result is that there are no terminals, it may cause the terminal to be unable to camp in a suitable cell or to fail to access the network randomly, thereby affecting the overall communication network performance and user experience.

[0108] The information transmission method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort should fall within the scope of protection of this disclosure.

[0109] Figure 3 shows a flowchart of an information transmission method provided in an embodiment of this application, which can be applied to a terminal. As shown in Figure 3, the method may include the following steps.

[0110] In step S301, the first information is sent to the network-side device.

[0111] The first piece of information is used to identify the relevant information of the terminal sending the wake-up signal.

[0112] In some possible implementations, the first information can be carried in a separate new communication message or reused in an existing communication message; this application does not impose any restrictions on this.

[0113] In some embodiments, the first information includes at least one of the following:

[0114] Target community information;

[0115] The information sent to wake up the signal;

[0116] Cell information related to the wake-up signal;

[0117] The first measurement result related to the wake-up signal;

[0118] The reason for sending the wake-up signal;

[0119] Second measurement result related to the wake-up signal.

[0120] The target cell information refers to the cell identifier of at least one target cell to which the terminal sends the wake-up signal. This can be a cell identifier or a list of cells. Sending the wake-up signal to at least one target cell means the terminal sends the wake-up signal to the network-side device corresponding to that target cell. When there is only one target cell, the target cell information can be a cell identifier. When there are multiple target cells, the target cell information can be a list of cells including the cell identifiers corresponding to each of the multiple target cells.

[0121] The first measurement result is the result after the terminal sends the wake-up signal, and the second measurement result is the result before the terminal sends the wake-up signal.

[0122] In some embodiments, the first measurement result may be the measurement result of a fourth time period after the terminal sends a wake-up signal, and the second measurement result may be the measurement result of a fifth time period before the terminal sends a wake-up signal.

[0123] In some embodiments, the fourth time period may be a preset fourth time period or a time period determined by receiving indication information from the network-side device. The fifth time period may be a preset fifth time period or a time period determined by receiving indication information from the network-side device. This application does not impose any restrictions on this.

[0124] It should be noted that the start and end times of the preset time period and the length of the preset time period in this application can be flexibly set as needed, and this application does not impose any restrictions on this.

[0125] The wake-up signal transmission information includes at least one of the following: transmission identification information, a timestamp of the wake-up signal transmission, transmission power of the wake-up signal transmission, and frequency domain resource information of the wake-up signal transmission. The transmission identification information identifies whether the terminal has transmitted a wake-up signal to the network-side device within the first time period. The timestamp of the wake-up signal transmission identifies the timestamp when the terminal transmitted the wake-up signal. The transmission power of the wake-up signal identifies the terminal's transmission power when it transmitted the wake-up signal. The frequency domain resource information of the wake-up signal identifies the corresponding frequency domain resource information when the terminal transmitted the wake-up signal.

[0126] In some possible implementations, the identification information can be explicit. For example, an explicit bit in the first information can indicate whether the terminal has sent a wake-up signal to the network-side device within the first time period to wake up at least one target cell. For example, if the bit is "0", it indicates that the terminal has not sent a wake-up signal to the network-side device within the first time period, and if the bit is "1", it indicates that the terminal has sent a wake-up signal to the network-side device within the first time period.

[0127] In another possible implementation, the presence or absence of a sending identification information in the first information can indicate whether the terminal has sent a wake-up signal to the network-side device within the first time period. That is, if the first information includes a sending identification information, it indicates that the terminal has sent a wake-up signal to the network-side device within the first time period, while if the first information does not include a sending identification information, it indicates that the terminal has not sent a wake-up signal to the network-side device within the first time period.

[0128] In another possible implementation, the identification information can also be implicit. For example, it can be implicitly identified whether a wake-up signal has been sent to the network-side device within the first time period by whether the first information includes a preset field. For example, the preset field can be the timestamp of the wake-up signal. If the first information includes the timestamp of the wake-up signal, it indicates that the terminal has sent a wake-up signal to the network-side device within the first time period. If the first information does not include the timestamp of the wake-up signal, it indicates that the terminal has not sent a wake-up signal to the network-side device within the first time period.

[0129] In some embodiments, the first time period can be the time period before the terminal performs the first operation. The first operation may be, for example, recording a minimized drive test log or recording a random access report. The first time period can be a preset first time period or a time period determined by receiving indication information from the network-side device. This application does not limit this. That is, the terminal can determine the transmission identification information based on whether it has sent a wake-up signal to the network-side device within the first time period before the first operation, and record the transmission identification information explicitly or implicitly in the minimized drive test log corresponding to the first operation, or in the random access report.

[0130] In some possible implementations, the frequency domain resource information for sending the wake-up signal may include at least one of the following:

[0131] Absolute frequency information;

[0132] Frequency location;

[0133] Bandwidth;

[0134] Subcarrier spacing;

[0135] Multiple wake-up signals can be reused.

[0136] Taking the NR system as an example, the absolute frequency point information can be, for example, absolute frequency point A.

[0137] The cell information associated with the wake-up signal includes at least one of the following: historical cell information, first cell information.

[0138] The historical camping cell information includes at least one of the following: historical camping cell identifier, historical camping beam identifier, and historical camping duration; the historical camping cell identifier is the cell identifier of the historical camping cell, the historical camping beam identifier is the identifier of the beam selected for camping in the historical camping cell, the historical camping duration is the camping duration of the terminal in the historical camping cell, and the historical camping cell is at least one camping cell in the second time period before the terminal sends a wake-up signal.

[0139] The first camping cell information includes at least one of the following: first camping cell identifier, first camping beam identifier, first camping duration, the first camping cell identifier is the cell identifier of the first camping cell, the first camping beam identifier is the identifier of the beam selected for camping in the first camping cell, the first camping duration is the camping duration of the terminal in the first camping cell, and the first camping cell is the camping cell in which the terminal successfully camped due to the wake-up signal.

[0140] It is understandable that the number of historical cell information entries can be multiple or one. When there are multiple historical cell information entries, the historical cell information corresponding to the multiple historical cells that the terminal has successively entered can be recorded in a preset order (such as the order of the time of entry).

[0141] Taking the information of the first stationed cell corresponding to the first stationed cell as an example, we will explain the first stationed cell identifier, the first stationed beam identifier, the first stationed duration, and the historical stationed cell information, which are similar and will not be elaborated here.

[0142] The first camping cell is the cell in which the terminal successfully camps due to a wake-up signal. In other words, the first camping cell is the cell in which the terminal sends a wake-up signal to the cell and successfully camps. For example, the terminal can send a wake-up signal to the network-side equipment corresponding to cells A and B, and after the network-side equipment restarts all SSBs of cells A and B, it can successfully camp on cell A. Then cell A can be regarded as the first camping cell.

[0143] The first camping cell can also include multiple beams (e.g., SSBs). For example, cell A can include n SSBs from A1 to An. After the terminal sends a wake-up signal, it camps on SSBA2 in cell A, and SSBA2 can be used as the identifier of the first camping beam.

[0144] Understandably, the number of cells to be camped first can be one, and the number of beams to be camped first can also be one. For example, a terminal can send a wake-up signal to the network-side equipment corresponding to cells A and B, and successfully camp on cell A after the network-side equipment reactivates all SSBs in cells A and B. Specifically, once the terminal measures an SSB that meets a preset threshold, it will camp on that cell and determine the first camped cell and the first camped beam. Suppose that at the terminal's location, the channel quality of SSB A3 in cell A is actually higher than that of SSB A2, but if the terminal first measures that SSB A2 meets the preset threshold, and has not yet measured SSB A3, then the terminal will camp on SSB A2, not SSB A3. In this case, the first camped beam is SSB A2, not SSB A3.

[0145] It is understandable that the number of first measurement results can be one or more, and the multiple first measurement results included in the first information can be sorted in a preset order (such as the strength of wireless channel quality or time order).

[0146] For example, taking the first information as including the first dwell time and the timestamp of sending the wake-up signal, suppose the terminal enters the coverage area of ​​cell 1, but because cell 1 is an energy-saving cell, the terminal initially fails to successfully camp. After the terminal sends the wake-up signal, it successfully camps in the cell and generates the first information 1. At this time, the following two situations may exist:

[0147] Scenario 1: After a period of time, cell 1 shuts down a certain SSB, the terminal sends a wake-up signal again, and generates the first information 2.

[0148] Scenario 2: The terminal leaves cell 1 first, cell 1 shuts down a certain SSB, and then the terminal re-enters the coverage area of ​​the cell, sends a wake-up signal again, and generates the first information 3.

[0149] At this time, the network-side device can distinguish between the above-mentioned situation 1 and situation 2 by combining the first dwell time in the first information 2 or the first information 3 and the timestamp of sending the wake-up signal. Situation 1 has the problem of prematurely shutting down the SSB, while request 2 does not have the problem of prematurely shutting down the SSB. Therefore, the network-side device can optimize the SSB shutdown strategy in the energy-saving cell based on the first information, thereby improving the communication network performance and user experience.

[0150] In another embodiment, if the first dwell time in multiple wake-up signal reports sent by the terminal is less than a preset duration threshold, the network-side device can also ignore the wake-up signal sent by the terminal, thereby preventing the terminal from frequently sending wake-up signals due to occasional signal fluctuations, thus ensuring the performance of the energy-saving cell.

[0151] The reason for sending a wake-up signal can be called the purpose of the terminal sending the wake-up signal.

[0152] In some embodiments, the reason for sending a wake-up signal may include one of the following:

[0153] The terminal is outside the network's coverage area;

[0154] System message not parsed successfully;

[0155] The paging message could not be parsed successfully.

[0156] Among them, "out of coverage" indicates that the terminal cannot camp on a suitable cell, for example, the radio channel quality of all searched SSBs is below the threshold.

[0157] Unsuccessful parsing of system messages indicates that the terminal failed to perform DCI (Downlink Control Information) on the PDCCH (Physical Downlink Control Channel) of the system message (e.g., SIB1) through blind detection of system messages via SI-RNTI, or that the terminal failed to parse system messages (e.g., SIB1) in the PDSCH (Physical Downlink Shared Channel) based on the DCI information.

[0158] Failure to parse the paging message indicates that the terminal failed to perform a blind detection of the PDCCH DCI of the paging message via P-RNTI, or that the terminal failed to parse the paging message in the PDSCH based on the DCI information.

[0159] In some embodiments, the reasons for sending a wake-up signal may also include one of the following:

[0160] Reselection of communities related to energy-saving communities;

[0161] Community selection related to energy-saving communities.

[0162] Among them, cell reselection related to energy-saving communities and cell selection related to energy-saving communities indicate that when the terminal performs cell reselection or re-selects a cell, the selected cell is an energy-saving community and is in an energy-saving state. Optionally, the reasons for cell reselection related to energy-saving communities include at least one of the following:

[0163] The cell selected in the cell reselection criteria is an energy-saving cell, and the terminal has obtained a valid uplink wake-up signal configuration;

[0164] The cell selected in the cell reselection criteria is an energy-saving cell, and the cell quality measured or predicted by the terminal is greater than a threshold, and the terminal has obtained a valid uplink wake-up signal configuration;

[0165] The cell selected in the cell reselection criteria is an energy-saving cell, and the terminal has obtained a valid uplink wake-up signal configuration, and the terminal does not have any urgent or high-priority services to send.

[0166] In some embodiments, the second time period can be the time period before the terminal sends a wake-up signal. The second time period can be a preset second time period or a time period determined by receiving indication information from the network-side device; this application does not impose any limitations on this. The second measurement result records the wireless channel quality information measured during the second time period before the terminal sends a wake-up signal. This helps the network-side device determine, based on the second measurement result, the coverage gaps caused by SSB shutdown or adjustment due to energy saving or other reasons, such as the terminal's inability to camp on a suitable cell, or the probability of random access process failure and / or corresponding wireless channel quality information. This helps the network optimize the shutdown or adjustment of cell SSBs, improving communication network performance and user experience.

[0167] It is understandable that the first information may also include the reason for sending the wake-up signal and the aforementioned second measurement result, thereby providing the network-side device with more detailed information about sending the wake-up signal.

[0168] In some embodiments, the terminal may also perform corresponding measurements within a preset time period after sending the wake-up signal, and include the corresponding first measurement result in the first information, thereby enabling the network-side device to more accurately assess the impact of coverage holes caused by the shutdown of beams in energy-saving cells based on the first measurement result.

[0169] In some embodiments, the first measurement result associated with the wake-up signal includes at least one of the following:

[0170] The first cell list includes at least one cell sorted according to a first preset rule, or the first cell list includes at least one cell sorted according to a first preset rule and whose wireless channel quality is higher than or equal to a first threshold.

[0171] The radio channel quality information of the first cell, wherein the first cell is at least one cell associated with the first cell list;

[0172] A first beam list, comprising at least one beam ordered according to a second preset rule, or, the first beam list ordered according to a second preset rule and having at least one beam with a wireless channel quality higher than or equal to a second threshold, wherein the first beam list is associated with the first cell list.

[0173] The wireless channel quality information of the first beam, which is at least one beam associated with the first beam list.

[0174] In some possible implementations, the terminal can perform measurements within a preset time period after sending the wake-up signal and generate a first cell list in any of the following ways:

[0175] Method 1: Sort the cells in the measurement results according to the first preset rule, and use the cell list consisting of at least one sorted cell as the first cell list.

[0176] Method 2: Select at least one cell from the measurement results whose wireless channel quality is higher than or equal to a first threshold, and sort the selected at least one cell according to a first preset rule. The resulting cell list of at least one sorted cell is used as the first cell list. Alternatively, sort multiple cells according to the first preset rule, and then select at least one cell from the sorted cell list whose wireless channel quality is higher than or equal to a second threshold. The resulting cell list of at least one cell is used as the first cell list. After generating the first cell list, the terminal can select at least one associated first cell from the first cell list and send the first cell list and / or the wireless channel quality information of the first cell as the content of the first information to the network-side device.

[0177] In some embodiments, if cells with wireless channel quality higher than or equal to the first threshold cannot be obtained through the above-described method two, the first cell list can be obtained through method one, so as to send the first cell list to the network-side device through the first information, thereby assisting the network-side device in making network energy-saving decisions and performance evaluations, and improving communication network performance and user experience.

[0178] The aforementioned first preset rule can be arranged in descending order of wireless channel quality, or it can be arranged in the order of the time when the measurement results are obtained. Selecting at least one associated first cell from the first cell list can be selecting at least one cell at any position in sequence (e.g., the head, i.e., the first in the sort), or it can be all cells in the first cell list. This application does not limit this.

[0179] In another possible implementation, the terminal can perform measurements within a preset time period after sending the wake-up signal and generate a first beam list in any of the following ways:

[0180] Method 3: Sort the beams in the measurement results according to the second preset rule, and use the beam list composed of at least one sorted beam as the first beam list.

[0181] Method 4: Select at least one beam from the measurement results whose wireless channel quality is higher than or equal to a second threshold, and sort the selected at least one beam according to a second preset rule. The resulting beam list is then used as the first beam list. Alternatively, sort multiple beams according to the second preset rule, and then select at least one beam from the sorted beam list whose wireless channel quality is higher than or equal to the second threshold. The resulting beam list is then used as the first beam list. After generating the first beam list, the terminal can select at least one associated first beam from the first beam list and send the first beam list and / or the wireless channel quality information of the first beam as the content of the first information to the network-side device.

[0182] In some embodiments, if a beam with a wireless channel quality higher than or equal to the second threshold cannot be obtained through the above-described method four, a first beam list can be obtained through method three, so as to send the first beam list to the network-side device through the first information, thereby assisting the network-side device in making network energy-saving decisions and performance evaluations, and improving communication network performance and user experience.

[0183] The aforementioned second preset rule can be arranged in descending order of wireless channel quality, or in the order of the time when the measurement results are obtained. Selecting at least one associated first beam from the first beam list can be selecting at least one beam at any position (e.g., the head, i.e., the one at the beginning of the sort) in sequence, or it can be all the beams in the first beam list. This application does not limit this.

[0184] In some embodiments, the first measurement result may include measurement results within one measurement period, or measurement results within multiple measurement periods. When the first measurement result includes measurement results from multiple measurement periods, it may include a list of first cells, radio channel quality information of the first cells, a list of first beams, and radio channel quality information of the first beams, each corresponding to one of the multiple measurement periods. The measurement results within multiple measurement periods may be arranged in chronological order according to the associated measurement periods, and the list of first cells and the list of first beams within each measurement period may be arranged in descending order of radio channel quality.

[0185] It should be noted that the beams included in the first beam list can be beams within the same cell or beams within different cells, but the cells where the beams in the first beam list are located are all in the first cell list. That is, the first beam list is associated with the first cell list. For example, the beams in the first beam list can be distinguished by using a cell identifier + beam identifier.

[0186] The content of the first information sent by the terminal can be any combination of the first cell list, the first beam list, the wireless channel quality information of the first cell, and the wireless channel quality information of the first beam. This application will not elaborate on each of these.

[0187] The terminal reports the radio channel quality information of the first cell and the first beam, enabling network-side equipment to optimize subsequent beam shutdown or adjustment strategies based on this information. For example, based on the beam with the strongest radio channel quality in the first beam list, the network can determine the SSB that provides the best service quality to the terminal after enabling all SSBs. Furthermore, if the radio channel quality of multiple SSBs in the first beam list is higher than a preset threshold, it indicates overlapping coverage at the terminal's location. This also helps network-side equipment make energy-saving decisions, such as shutting down some SSBs while ensuring the terminal's location does not exceed network coverage.

[0188] Understandably, the difference between the first measurement result and the first camping cell information lies in the fact that the first camping cell and the first camping beam do not represent the cell and beam with the best radio channel quality that can be measured at the terminal's location. Specifically, once the terminal measures an SSB that meets a preset threshold, it will camp on that cell and determine the first camping cell and the first camping beam. For example, at the terminal's location, the radio channel quality of SSB A3 in cell A is actually higher than that of SSB A2 in cell A. However, if the terminal first measures that SSB A2 meets the preset threshold, and has not yet measured SSB A3, then the terminal will camp on SSB A2, not SSB A3. In this case, the first camping beam is SSB A2, not SSB A3. After the terminal camps on SSB A2 in cell A, it can continue to measure, thus measuring that SSB A3 is the SSB with the strongest radio signal quality at the terminal's location. Therefore, SSB A3 can be included in the first beam list of the first measurement result, and the radio channel quality information of the first beam can include the radio channel quality of SSB A3.

[0189] In some embodiments, the second measurement result may include at least one of the following:

[0190] The radio channel quality information of the second cell, wherein the second cell is at least one cell associated with a historically camped cell identifier.

[0191] The wireless channel quality information of the second beam, wherein the second beam is at least one beam associated with a historically residing beam identifier.

[0192] The terminal reporting the radio channel quality information of the second cell and / or the second beam allows network-side equipment to determine whether the currently configured SSB will cause the terminal to exceed network coverage, and provides detailed information on the corresponding radio channel quality. Furthermore, by combining the radio channel quality information of the first cell and / or the first beam, the changes in radio coverage before and after enabling the wake-up signal can be analyzed, assisting in network energy-saving decisions and performance evaluation.

[0193] It should be noted that the aforementioned wireless channel quality can be represented in various ways, such as RSRP (Reference Signal Receiving Power), RSRQ (Reference Signal Receiving Quality), SINR (Signal to Interference plus Noise Ratio), BLER (Block Error Rate), BER (Bit Error Rate), and packet loss rate. It can be understood that when RSRP, RSRQ, or SINR are used to represent wireless channel quality, a wireless channel quality above or equal to a threshold indicates that the corresponding RSRP, RSRQ, or SINR is greater than or equal to the threshold. Conversely, when BLER, BER, and packet loss rate are used to represent wireless channel quality, a wireless channel quality above or equal to a threshold indicates that the corresponding BLER, BER, or packet loss rate is less than or equal to the threshold.

[0194] By adopting the above technical solution, the network-side device can obtain first information from the terminal, including information related to the wake-up signal sent by the terminal. Based on the information related to the wake-up signal sent by the terminal in the first information, it can assist in making network energy-saving decisions and performance evaluations, thereby improving communication network performance and user experience.

[0195] The terminal can be triggered to send the first information to the network-side device in various ways. In some preferred embodiments, after the terminal enters the connected state, the network-side device can send a first information request to the terminal, and the terminal can respond to the first information request sent by the network-side device by sending the first information.

[0196] In some embodiments, the terminal may also report to the network side whether it has the ability to send first information, so that the network side device can send a first request to the terminal with the ability to send first information, and the terminal can send first information in response to receiving the first information request sent by the network side device.

[0197] In other embodiments, after entering the connected state, the terminal can periodically send signals to the network-side device based on a preset sending period, or it can be triggered by certain conditions or events, such as the duration of the wake-up signal sent by the terminal exceeding a preset duration threshold.

[0198] Figure 4 shows another flowchart of the information transmission method provided in the embodiments of this application. As shown in Figure 4, the method may further include the following steps.

[0199] In step S401, the network-side device is notified whether it has the capability to send the first information.

[0200] In some possible implementations, the terminal can indicate whether it has the ability to send the first information through a newly added field in the terminal capability reporting message in related technologies. Of course, the terminal can also report whether it has the ability to send the first information to the network-side device through the newly added message. This application does not limit this.

[0201] By adopting the above technical solution, the network-side device can proactively report whether it has the ability to send the first information, so that the network-side device can obtain the first information from the terminal with the ability to send the first information, thereby improving the performance of the communication network and the user experience.

[0202] In some embodiments, the first information may include any one of the following:

[0203] Wake-up signal report;

[0204] Random access report;

[0205] Minimize road test logs.

[0206] The following detailed description will be provided with reference to some specific embodiments.

[0207] Example 1

[0208] In some embodiments, the first information may be a wake-up signal report. Figure 5 shows another flowchart of the information transmission method provided in this application embodiment. The scenario in this embodiment is that the terminal shown in Figure 2(a) or Figure 2(b) cannot camp on a suitable cell. As shown in Figure 5, when the first information is a wake-up signal report, step S301 may be step S502 in Figure 5. The information transmission method may include the following steps:

[0209] In step S501, if the first condition is met, a wake-up signal is sent to at least one network-side device corresponding to the first target cell.

[0210] The first target cell includes at least one of the following:

[0211] The terminal is currently residing in the cell;

[0212] The terminal's neighboring cells;

[0213] The third cell list consists of cells whose wireless channel quality is higher than or equal to the third threshold. The third cell list is the cell list in the wake-up configuration received by the terminal.

[0214] The first condition includes at least one of the following:

[0215] The measured wireless channel quality of both the current cell and neighboring cells is below the fourth threshold;

[0216] The measured wireless channel quality of all beams in the currently camped cell is below the fifth threshold;

[0217] System message not parsed successfully;

[0218] The paging message could not be parsed successfully.

[0219] In some embodiments, the first condition further includes that the terminal has a valid wake-up signal configuration and that the cell selected according to the cell reselection criteria is an energy-saving cell.

[0220] In another embodiment, the first condition may further include at least one of the following:

[0221] The wireless channel quality of the energy-saving community is higher than or equal to the sixth threshold;

[0222] Data transmission for preset services was not triggered.

[0223] Among them, the preset service can be at least one of the emergency service and the high priority service.

[0224] In step S502, a wake-up signal report is sent to the network-side device.

[0225] In some possible implementations, a wake-up signal report can be generated within a preset time period after the wake-up signal is sent.

[0226] In some possible implementations, a wake-up signal report can be sent in response to a wake-up signal report request received from a network-side device.

[0227] In some embodiments, before sending a wake-up signal report to the network-side device, the method further includes: receiving a wake-up signal report request sent by the network-side device.

[0228] Among them, the wake-up signal report request is used to request the terminal to send a wake-up signal report.

[0229] In some possible implementations, the terminal may send a wake-up signal report to the network-side device in response to receiving a wake-up signal report request from the network-side device.

[0230] In some embodiments, a wake-up signal report may include at least one of the following:

[0231] First residential area sign;

[0232] First residing beam identifier;

[0233] Timestamp of the wake-up signal sent;

[0234] The reason for sending the wake-up signal;

[0235] First length of stay;

[0236] Target community information;

[0237] First community list;

[0238] First beam list;

[0239] The beam identifier of the highest quality wireless channel beam in the cells of the first cell list.

[0240] The content of the wake-up signal report has been described in detail in the foregoing embodiments and will not be repeated here.

[0241] The beneficial effect of obtaining wake-up signal reports from network-side terminals is that it enables network-side devices to make network energy-saving decisions and performance evaluations after adjusting the SSB configuration of the cell based on the received wake-up signal (e.g., enabling all SSBs in the cell).

[0242] For example, the relevant cells and / or relevant SSBs that resolve the terminal's impending network coverage issues can be determined based on the first camped cell and / or the first camped beam. It can also be determined whether overlapping coverage exists based on the first cell list and / or the first beam list. Furthermore, the beam with the strongest wireless channel quality at the terminal's location can be determined based on the beam with the strongest wireless channel quality in the first beam list.

[0243] It is understandable that the terminal may send wake-up signal reports in various forms. For example, multiple wake-up signal reports may be combined into a list and sent to the network-side device at once. Alternatively, multiple wake-up signal reports may be sent to the network-side device in multiple installments. This application does not impose any restrictions on this.

[0244] By adopting the above technical solution, the network-side device can obtain a wake-up signal report from the terminal, including information related to the wake-up signal sent by the terminal. Based on the information related to the wake-up signal sent by the terminal in the wake-up signal report, the device can assist in making network energy-saving decisions and performance evaluations, thereby improving communication network performance and user experience.

[0245] Example 2

[0246] In some embodiments, the first information may be a random access report. In this embodiment, the scenario is as shown in Figure 2(c), after the terminal camps on a suitable cell, it moves to a coverage hole. At this time, the terminal has an uplink service transmission requirement and initiates random access, but the random access fails. Figure 6 shows another flowchart of the information transmission method provided in this application embodiment. As shown in Figure 6, step S301 may be step S603 in Figure 6. The information transmission method may include the following steps:

[0247] In step S601, if the second condition is met, a wake-up signal is sent to the network-side device corresponding to the currently camped cell.

[0248] The second condition is that the wireless channel quality of all beams in the currently camped cell is lower than the seventh threshold, and the terminal has an uplink service transmission requirement.

[0249] In some embodiments, when sending a wake-up signal to the currently camped cell, a beam of the currently camped cell can be randomly selected to send the wake-up signal to the network-side device.

[0250] In step S602, a random access report is generated.

[0251] In some embodiments, a random access report may be generated after the terminal sends a wake-up signal and initiates a random access attempt. Alternatively, a random access report may be generated after the terminal sends a wake-up signal, initiates a random access attempt, and the random access is successful; this application does not limit the scope of the invention.

[0252] In step S603, a random access report is sent to the network-side device.

[0253] In some possible implementations, a random access report can be sent in response to a random access report request received from a network-side device.

[0254] In some embodiments, the random access report may include sending identification information, that is, indication information indicating whether the terminal has sent a wake-up signal to the network-side device within a first time period.

[0255] In some possible implementations, a transmission identification information can be added to the random access report in the relevant technology, and in response to the random access report request from the network-side device, a random access report with the added transmission identification information can be sent to the network-side device.

[0256] In some embodiments, the random access report may also include the beam identifier that initiated the random access, whether the wireless channel quality of the beam is higher than a preset threshold, the number of random access preambles sent based on the beam, and whether the terminal detected contention for random access.

[0257] To illustrate the benefits of adding identification information to the random access report, consider a specific example. Assume that cell 1 in the network device has SSB 1, SSB 2, and SSB 4 enabled. However, for terminal 1, the measurement results of all SSBs are below a preset threshold. At this point, terminal 1 sends a wake-up signal to the network device, which then enables SSB 3 and SSB 5. Terminal 1 detects that SSB 5 has the highest radio channel quality, while terminal 2 detects that SSB 3 has the highest radio channel quality. Terminal 1 sends msg1 based on SSB 5, and terminal 2 sends msg1 based on SSB 3. Ultimately, both terminal 1 and terminal 2 successfully access the network. Because terminal 1 did not directly initiate random access when the measurement results of all SSBs were below the preset threshold, causing a random access failure, but instead first sent a wake-up signal, there is no record of a random access failure when the network device requests a random access report from terminal 1. Therefore, the network device cannot distinguish whether the coverage vulnerability was caused by the disabling of SSB 3 or SSB 5.

[0258] When terminal 1 sends the sending identification information (it has previously sent a wake-up signal), the network-side device can know that there is a terminal distribution prediction error in the SSB 5 accessed by the terminal, or that there is a coverage hole when SSB 5 is turned off.

[0259] By adopting the above technical solution, the network-side device can obtain a random access report from the terminal, including information related to the wake-up signal sent by the terminal. Based on the information related to the wake-up signal sent by the terminal in the random access report, it can assist in making network energy-saving decisions and performance evaluations, thereby improving communication network performance and user experience.

[0260] Example 3

[0261] In some embodiments, the first information may be a minimized drive test report. Figure 7 shows another flowchart of the information transmission method provided in this application embodiment. The scenario in this embodiment is that the terminal shown in Figure 2(a) or Figure 2(b) cannot camp on a suitable cell. As shown in Figure 7, step S301 may specifically include the following steps:

[0262] In step S701, if the first condition is met, a wake-up signal is sent to at least one network-side device corresponding to the first target cell.

[0263] The first target cell includes at least one of the following:

[0264] The terminal is currently residing in the cell;

[0265] The terminal's neighboring cells;

[0266] The second cell list consists of cells whose wireless channel quality is higher than or equal to the third threshold. The second cell list is the cell list in the wake-up configuration received by the terminal.

[0267] The first condition includes at least one of the following:

[0268] The measured wireless channel quality of both the current cell and neighboring cells is below the fourth threshold;

[0269] The measured wireless channel quality of all beams in the currently camped cell is below the fifth threshold;

[0270] System message not parsed successfully;

[0271] The paging message could not be parsed successfully.

[0272] In some embodiments, the first condition further includes that the terminal has a valid wake-up signal configuration and that the cell selected according to the cell reselection criteria is an energy-saving cell.

[0273] In another embodiment, the first condition may further include at least one of the following:

[0274] The wireless channel quality of the energy-saving community is higher than or equal to the sixth threshold;

[0275] Data transmission for preset services was not triggered.

[0276] Among them, the preset service can be at least one of the emergency service and the high priority service.

[0277] In step S702, if the first event triggering condition is met, the minimized road test log is recorded.

[0278] The first event trigger condition includes any one of the following:

[0279] A wake-up signal has been sent;

[0280] A wake-up signal was sent, and the system successfully remained active during the third time period.

[0281] The terminal is outside the network's coverage area.

[0282] Among them, "out of coverage" indicates that the terminal cannot camp on a suitable cell, for example, the wireless channel quality of all searched SSB beams is below the threshold.

[0283] In step S703, a minimized drive test log is sent to the network-side device.

[0284] In some possible implementations, a minimized drive test log can be sent in response to a minimized drive test log request received from a network-side device.

[0285] In some embodiments, minimizing road test logs includes at least one of the following:

[0286] Send identification information;

[0287] Timestamp of the wake-up signal sent;

[0288] First length of stay.

[0289] In some embodiments, minimizing road test logs may further include at least one of the following:

[0290] Community signage for residents staying in the residential area;

[0291] Beamform of the residential area;

[0292] Duration of stay in the residential community;

[0293] Wireless channel quality information of the residential cell;

[0294] Wireless channel quality information for the residing beam;

[0295] Neighboring residential area signs;

[0296] Wireless channel quality information of neighboring cells;

[0297] Beam identifiers in adjacent cells;

[0298] The wireless channel quality of beams in adjacent cells.

[0299] To illustrate the benefits of adding first information to the minimized drive test log, consider this specific example: when a terminal detects an impending out-of-coverage event, it can send a wake-up signal to the network-side device. The network-side device can then adjust its SSB configuration (e.g., enabling more or all SSBs) in response to the received wake-up signal, effectively preventing the terminal from experiencing out-of-coverage issues. Current minimized drive test logs cannot record cases where the terminal successfully camps after sending a wake-up signal. Furthermore, in current technologies, if the minimized drive test log is event-triggered, the triggering event only includes out-of-coverage. However, if the terminal successfully camps after sending a wake-up signal, but does not experience an out-of-coverage issue, it will not be recorded in the minimized drive test log. By adding first information to the minimized drive test log, it is possible to record cases where the terminal is about to exceed the network's coverage area but successfully camps by sending a wake-up signal.

[0300] By adopting the above technical solution, the network-side device can obtain a minimized drive test log from the terminal, including information related to the terminal sending wake-up signals. Based on the information related to the terminal sending wake-up signals in the minimized drive test log, it can assist in making network energy-saving decisions and performance evaluations, thereby improving communication network performance and user experience.

[0301] Figure 8 shows another flowchart of the information transmission method provided in this application embodiment, applied to a network-side device. As shown in Figure 8, the method may include the following steps.

[0303] The first piece of information is used to identify the relevant information of the terminal sending the wake-up signal.

[0304] In some possible implementations, the first information can be carried in a separate new communication message or reused in an existing communication message; this application does not impose any restrictions on this.

[0305] In some embodiments, the first information includes at least one of the following:

[0306] Target cell information, which is the cell identifier of at least one target cell to which the terminal sends the wake-up signal;

[0307] The information sent to wake up the signal;

[0316] In some embodiments, the reason for sending a wake-up signal may include one of the following:

[0317] The terminal is outside the network's coverage area;

[0318] System message not parsed successfully;

[0319] The paging message could not be parsed successfully.

[0320] Among them, "out of coverage" indicates that the terminal cannot camp on a suitable cell, for example, the radio channel quality of all searched SSBs is below the threshold.

[0321] The failure to parse system messages indicates that the terminal failed to perform DCI on the PDCCH (Physical Downlink Control Channel) of the system message (e.g., SIB1) through blind detection of system messages via SI-RNTI, or that the terminal failed to parse system messages (e.g., SIB1) in the PDSCH (Physical Downlink Shared Channel) based on the DCI information.

[0322] Failure to parse the paging message indicates that the terminal failed to perform a blind detection of the PDCCH DCI of the paging message via P-RNTI, or that the terminal failed to parse the paging message in the PDSCH based on the DCI information.

[0333] The wireless channel quality information of the second beam, wherein the second beam is at least one beam associated with a historically residing beam identifier.

[0334] By adopting the above technical solution, the network-side device can obtain first information from the terminal, including information related to the wake-up signal sent by the terminal. Based on the information related to the wake-up signal sent by the terminal in the first information, it can assist in making network energy-saving decisions and performance evaluations, thereby improving communication network performance and user experience.

[0336] In step S901, it is determined whether the terminal has the capability to send the first information.

[0337] In some possible implementations, the terminal can indicate whether it has the ability to send the first information through a newly added field in the terminal capability reporting message in related technologies.

[0339] The following detailed description will be provided with reference to some specific embodiments.

[0340] Example 4

[0341] In some embodiments, the first information may be a wake-up signal report. FIG10 shows another flowchart of the information transmission method provided in the embodiments of this application. The scenario of this embodiment is that the terminal shown in FIG2(a) or FIG2(b) cannot camp on a suitable cell. As shown in FIG10, step S801 may be step S1003 in FIG10. The information transmission method may include the following steps.

[0342] In step S1001, a wake-up signal is received from the terminal.

[0343] The wake-up signal is sent by the terminal when the first condition is met, and is used to turn on at least one beam that is in a closed state in the first target cell.

[0344] The first target cell includes at least one of the following:

[0345] The terminal is currently residing in the cell;

[0346] The terminal's neighboring cells;

[0347] The second cell list consists of cells whose wireless channel quality is higher than or equal to the third threshold. The second cell list is the cell list in the wake-up configuration received by the terminal.

[0348] The first condition includes at least one of the following:

[0349] The measured wireless channel quality of both the current cell and neighboring cells is below the fourth threshold;

[0350] The measured wireless channel quality of all beams in the currently camped cell is below the fifth threshold;

[0351] System message not parsed successfully;

[0352] The paging message could not be parsed successfully.

[0353] In some embodiments, the first condition further includes that the terminal has a valid wake-up signal configuration and that the cell selected according to the cell reselection criteria is an energy-saving cell.

[0354] In another embodiment, the first condition may further include at least one of the following:

[0355] The wireless channel quality of the energy-saving community is higher than or equal to the sixth threshold;

[0356] Data transmission for preset services was not triggered.

[0357] Among them, the preset service can be at least one of the emergency service and the high priority service.

[0358] In some embodiments, the wake-up signal may also include at least one recommended beam from one or more target cells to activate at least one recommended beam from one or more target cells.

[0359] In step S1002, at least one beam in the target cell that is in a closed state is turned on.

[0360] In some embodiments, in response to receiving a wake-up signal, at least one beam in the target cell that is in a closed state can be turned on.

[0361] In some embodiments, if the wake-up signal includes at least one recommended beam from one or more target cells, then at least one recommended beam from one or more target cells may be turned on.

[0362] In step S1003, a wake-up signal report is received from the terminal.

[0363] In some embodiments, receiving a wake-up signal report from a terminal may specifically include the following steps:

[0364] In step 10, if the terminal has the ability to send a wake-up signal report, a wake-up signal report request is sent to the terminal.

[0365] For example, after a terminal enters the connected state, the network-side device can send a wake-up signal report request to a terminal that has the ability to send a wake-up signal report.

[0366] In step 11, the receiving terminal sends a wake-up signal report in response to the wake-up signal report request.

[0367] In some embodiments, a wake-up signal report may include at least one of the following:

[0368] First residential area sign;

[0369] First residing beam identifier;

[0371] The reason for sending the wake-up signal;

[0372] First length of stay;

[0373] Target community information;

[0374] First community list;

[0375] First beam list;

[0376] The beam identifier of the highest quality wireless channel beam in the cells of the first cell list.

[0377] For examples of how the specific terminal sends a wake-up signal report and how one or more pieces of information in the wake-up signal report can be used to solve technical problems, please refer to the description in Embodiment 1. These will not be elaborated upon here.

[0378] Understandably, network-side devices can adopt different energy-saving solutions. For example, network-side devices can turn off the beam to save energy, or they can change the beam's transmission period to an energy-saving period (for example, adjust the beam's transmission period from the normal transmission period T to nT, where n is an integer greater than or equal to 2) to save energy.

[0379] If the network-side equipment uses the method of changing the beam transmission period to the energy-saving period to achieve energy saving, which causes the terminal to be unable to camp on a suitable cell, step S1002 can be replaced by the following step S1002-1.

[0380] In step S1002-1, the transmission period of the beam with the transmission period of the energy-saving period is restored to the normal transmission period.

[0381] By adopting the above technical solution, the network-side device can obtain a wake-up signal report from the terminal, including information related to the wake-up signal sent by the terminal. Based on the information related to the wake-up signal sent by the terminal in the wake-up signal report, the device can assist in making network energy-saving decisions and performance evaluations, thereby improving communication network performance and user experience.

[0382] Example 5

[0383] In some embodiments, the first information may be a random access report. In this embodiment, the scenario is as shown in Figure 2(c), after the terminal camps on a suitable cell, it moves to a coverage hole. At this time, the terminal has an uplink service transmission requirement and initiates random access, but the random access fails. Figure 11 shows another flowchart of the information transmission method provided in this application embodiment. As shown in Figure 11, step S801 may be step S1103 in Figure 11. The information transmission method may include the following steps:

[0384] In step S1101, a wake-up signal is received from the terminal.

[0385] The wake-up signal is sent by the terminal when the second condition is met, and is used to turn on the beam that is in a closed state in the terminal's current camp cell.

[0386] The second condition is that the wireless channel quality of all beams in the currently camped cell is lower than the seventh threshold, and the terminal has an uplink service transmission requirement.

[0387] In some embodiments, the wake-up signal may also include at least one recommended beam from the currently camped cell to turn on at least one recommended beam from the currently camped cell.

[0388] In step S1102, the beam that is currently in the off state in the currently camped cell is turned on.

[0389] In some embodiments, in response to receiving a wake-up signal, a beam that is currently in a closed state in the currently camped cell may be turned on.

[0390] In some embodiments, the wake-up signal may also include at least one recommended beam from the currently camped cell, in which case at least one recommended beam from the currently camped cell can be turned on.

[0391] In step S1103, a random access report is received from the terminal.

[0392] In some embodiments, receiving a random access report from a terminal may include the following steps.

[0393] In step 20, if the terminal has the capability to send a random access report, a random access report request is sent to the terminal.

[0394] For example, after a terminal enters the connected state, the network-side device can send a random access report request to a terminal that has the ability to send a random access report.

[0395] In step 21, the receiving terminal sends a random access report in response to the random access report request.

[0396] In some embodiments, the random access report includes transmission identification information. In some embodiments, the random access report may also include the beam identifier that initiated the random access, whether the radio channel quality of the beam is higher than a preset threshold, the number of random access preambles transmitted based on the beam, and whether the terminal detected contention for random access.

[0397] For an example of resolving technical problems using information from the random access report, please refer to the description in Example 2; it will not be elaborated upon here.

[0398] Understandably, network-side devices can adopt different energy-saving solutions. For example, network-side devices can turn off the beam to save energy, or they can change the beam's transmission period to an energy-saving period (for example, adjust the beam's transmission period from the normal transmission period T to nT, where n is an integer greater than or equal to 2) to save energy.

[0399] If the network-side equipment uses the method of changing the beam transmission period to the energy-saving period to achieve energy saving, resulting in the terminal being unable to camp on a suitable cell, step S1102 can be replaced by the following step S1102-1.

[0400] In step S1102-1, the transmission period of the beam with the transmission period of the energy-saving period is restored to the normal transmission period.

[0401] By adopting the above technical solution, the network-side device can obtain a random access report from the terminal, including information related to the wake-up signal sent by the terminal. Based on the information related to the wake-up signal sent by the terminal in the random access report, it can assist in making network energy-saving decisions and performance evaluations, thereby improving communication network performance and user experience.

[0425] In some embodiments, receiving minimized road test logs from a terminal may include the following steps.

[0426] In step 30, if the terminal has the ability to send minimized road test logs, a minimized road test log request is sent to the terminal.

[0427] For example, after the terminal enters the connected state, the network-side device can send a minimized drive test log request to the terminal that has the ability to send minimized drive test logs.

[0428] In step 31, the receiving terminal sends the minimized drive test log in response to the minimized drive test log request.

[0429] Among them, the minimized road test log is recorded by the terminal when the first event trigger condition is met.

[0430] The first event trigger condition includes any one of the following:

[0431] A wake-up signal has been sent;

[0432] A wake-up signal was sent, and the system successfully remained active during the third time period.

[0433] The terminal is outside the network's coverage area.

[0434] In some embodiments, the third time period may be a preset third time period or a time period determined by receiving indication information from the network-side device; this application does not impose any restrictions on this.

For example, network-side devices can turn off the beam to save energy, or they can change the beam's transmission period to an energy-saving period (for example, adjust the beam's transmission period from the normal transmission period T to nT, where n is an integer greater than or equal to 2) to save energy.

[0451] If the network-side equipment uses the method of changing the beam transmission period to the energy-saving period to achieve energy saving, which causes the terminal to be unable to camp on a suitable cell, step S1202 can be replaced by the following step S1202-1.

[0452] In step S1202-1, the transmission period of the beam with the transmission period of the energy-saving period is restored to the normal transmission period.

[0453] By adopting the above technical solution, the network-side device can obtain a minimized drive test log from the terminal, including information related to the terminal sending wake-up signals. Based on the information related to the terminal sending wake-up signals in the minimized drive test log, it can assist in making network energy-saving decisions and performance evaluations, thereby improving communication network performance and user experience.

[0454] The information transmission method provided in this application can be executed by an information transmission device. This application uses an information transmission device executing the information transmission method as an example to illustrate the information transmission device provided in this application.

[0506] A wake-up signal was sent, and the system successfully remained active during the third time period.

[0507] The terminal is outside the network's coverage area.

[0508] In step 1305, the network-side device requests the sending of minimized drive test logs.

[0509] For example, after the terminal enters the connected state, the network-side device can send a minimized drive test log request to the terminal that has the ability to send minimized drive test logs.
