Description

Technical Field

[0001] The present application relates to the technical field of industrial communication, and particularly to a method for transmitting an uplink signal, a management station, a terminal station, and a system. Background Art

[0002] In the uplink of the current industrial wireless communication system, the terminal station sends an uplink synchronization signal to the management station on the uplink synchronization channel to establish time synchronization with the management station, ensuring that the uplink signals from different terminal stations are time-aligned at the management station. This synchronization ensures that the uplink signals from different terminal stations can reach the management station simultaneously, thereby improving the performance and efficiency of the system. The uplink reference signal is a reference signal used for channel estimation in the uplink, so that the management station can correctly demodulate the data in the uplink physical channel from the terminal station.

[0003] When no terminal station is accessing, there is no signal transmitted on the uplink synchronization channel, wasting spectrum resources; the uplink reference signal, like the uplink data, is only transmitted on the uplink shared channel and occupies a part of the bandwidth. Therefore, the channel measurement can only measure the channel state on a part of the bandwidth. Therefore, the current uplink signal has a low spectrum utilization rate during use and can only perform channel measurement on a part of the uplink bandwidth. Summary of the Invention

[0060] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0061] In the current field of industrial wireless communication, the uplink synchronization signal is used for terminal access. When there is no terminal accessing, there is no signal transmitted on the uplink synchronization channel, wasting spectrum resources. The uplink reference signal is used for channel measurement and, like the terminal uplink data, it is only transmitted on the uplink shared channel and occupies a part of the bandwidth. Therefore, the channel measurement can only measure the channel state on a part of the bandwidth. Therefore, the current uplink signal has a low spectrum utilization rate during use and can only perform channel measurement on a part of the uplink bandwidth.

[0062] Among them, the uplink synchronization signal is mainly used for time synchronization between the terminal and the management station to ensure that the terminal can correctly access the network. The uplink reference signal is used for the management station to measure the channel state in order to optimize data transmission.

[0063] Aiming at the problem that the spectrum resources of the uplink synchronization channel are vacant when there is no terminal accessing and the full-bandwidth channel state cannot be measured on the uplink channel, the embodiments of the present application provide a transmission method of the uplink signal, a management station, a terminal station, a system, and a storage medium.

[0064] Among them, the above full-bandwidth channel measurement refers to the measurement of channel state information within the entire frequency band range, while the partial-bandwidth channel measurement is only performed within a part of the frequency band range. The full-bandwidth measurement can provide more comprehensive channel state information, which helps to optimize network performance.

[0065] In the embodiments of the present application, the above transmission method of the uplink signal can be applied in Figure 1 the uplink signal transmission system shown in Figure 1 As a schematic diagram of an uplink signal transmission system, this system includes: a management station 101 and a terminal station 102. The configuration of the uplink signal can be realized through the interaction between the management station 101 and the terminal station 102. Figure 1 The uplink signal transmission system shown can be an industrial network communication system.

[0066] Exemplarily, in practical applications, the above management station 101 can include but is not limited to any one of the following device types:

[0067] (1) Industrial wireless controller / management station: It can be an industrial-grade wireless access point, responsible for managing wireless resource allocation, signal synchronization, and terminal access, and supporting multi-terminal concurrent access and channel state measurement. Exemplarily, such as 5G / 4G industrial routers, Wi-Fi 6GHz band devices (referred to as Wi-Fi 6E devices).

[0068] (2) Industrial control system devices: Programmable Logic Controller (PLC), industrial switch, or edge computing gateway. Among them, an integrated wireless communication module is used to realize real-time control and signal management of production equipment.

[0069] (3)Dedicated spectrum management equipment: An industrial wireless manager that supports dynamic spectrum allocation, such as a 5G industrial module or an industrial wireless controller.

[0070] Exemplarily, in practical applications, the above terminal station 102 may include, but is not limited to, any one of the following device types:

[0071] (1)Industrial sensors and actuators: Low-power wireless sensors (such as temperature and humidity sensors, vibration sensors), which access the network through protocols such as Zigbee and LoRa. Among them, Zigbee is a low-power local area network protocol, and LoRa is an ultra-long-distance wireless transmission solution based on spread spectrum technology.

[0072] (2)Industrial robots and automation equipment: Collaborative robots (Universal Robot 5e, UR5e) or Automated Guided Vehicle (AGV) carts, which achieve "full-bandwidth channel measurement" through a dedicated wireless communication interface to optimize the motion control accuracy.

[0073] (3)Monitoring and security equipment: Industrial cameras (such as explosion-proof cameras) or access control systems, which send "uplink signals for measurement" during the non-access phase to assist the management station in real-time monitoring of the channel quality.

[0074] In the embodiments of the present application, the above-mentioned transmission method of the uplink signal, and the specific application scenarios of the uplink signal transmission system may include, for example, smart factories, remote medical treatment, etc.

[0075] In an exemplary embodiment, as Figure 2 shown, a flowchart of a transmission method of an uplink signal is provided Figure 1 , taking this method applied to the Figure 1 uplink signal transmission system as an example, and taking the interaction between a terminal station and a management station as an example for illustration. The method may include the following steps:

[0076] 201. The management station sends uplink signal configuration information to the terminal station.

[0077] Correspondingly, the terminal station receives the uplink signal configuration information sent by the management station.

[0078] Among them, the uplink signal configuration information includes: signal indication information of the target uplink signal, the target uplink signal includes: an access uplink signal for access, and / or, a measurement uplink signal for measurement, and the signal indication information is used to instruct the terminal station to send the target uplink signal on the uplink synchronization channel.

[0079] In the above method for transmitting uplink signals, when configuring the uplink signals, the management station configures the access uplink signals for access and / or the measurement uplink signals for measurement to the terminal station, and the signal indication information indicates that the access uplink signals and / or the measurement uplink signals are transmitted on the uplink synchronization channel. Thus, when there is no access by the terminal station and the access uplink signals are not transmitted, the uplink synchronization channel can still be used to transmit the measurement uplink signals, and when the measurement uplink signals are transmitted on the uplink synchronization channel, channel measurement over the full bandwidth can be achieved, thereby improving the spectrum utilization rate and achieving channel measurement over the full uplink bandwidth.

[0080] In the embodiments of the present application, the uplink signal configuration information may include the following situations:

[0081] 1) The signal indication information of the access uplink signals may indicate: the access uplink signals, and indicate that the access uplink signals are transmitted on the uplink synchronization channel.

[0082] 2) The signal indication information of the measurement uplink signals may indicate: the measurement uplink signals, and indicate that the measurement uplink signals are transmitted on the uplink synchronization channel.

[0083] 3) The signal indication information of the access uplink signals and the signal indication information of the measurement uplink signals may indicate: the access uplink signals and the measurement uplink signals, and indicate that the access uplink signals and the measurement uplink signals are transmitted on the uplink synchronization channel.

[0084] In some embodiments, the above access uplink signals and measurement uplink signals are transmitted time-divisionally. That is to say, for a single terminal station, the access uplink signals and the measurement uplink signals are not transmitted simultaneously.

[0085] It should be noted that for a single terminal station, the access uplink signals and the measurement uplink signals cannot be transmitted simultaneously, but for different terminal stations, the access uplink signals and the measurement uplink signals can be transmitted simultaneously. Exemplarily, 2 terminal stations are allocated to transmit uplink signals at the same time. One terminal station has been accessed and can transmit measurement uplink signals, and the other terminal station is still in the access process and can transmit the above access uplink signals.

[0086] The signal indication information of the above target uplink signals may include but is not limited to the following configuration methods:

[0087] Configuration method 1: Configure the indexes of the access uplink signals and the indexes of the measurement uplink signals to the terminal station.

[0088] Among them, the number of terminal stations is at least one, and the signal indication information of the target uplink signals includes: the terminal identifier corresponding to each terminal station, the index of the target uplink signals.

[0089] Exemplarily, Figure 3It is a schematic diagram of Configuration Method 1. As shown in Figure 3 Figure (a) thereof, the number of terminal stations is one, and its corresponding terminal identifier is Terminal Identifier 1. The signal indication information of the target uplink signal includes: Terminal Identifier 1, the index of the access uplink signal corresponding to this Terminal Identifier 1, and the index of the measurement uplink signal.

[0090] Exemplarily, as shown in Figure 3 Figure (b) thereof, the number of terminal stations is multiple. The signal indication information of the target uplink signal includes: Terminal Identifier 1, the index of the access uplink signal corresponding to this Terminal Identifier 1 and the index of the measurement uplink signal; Terminal Identifier 2, the index of the access uplink signal corresponding to this Terminal Identifier 2 and the index of the measurement uplink signal, each other terminal identifier, and the index of the access uplink signal and the index of the measurement uplink signal corresponding to each terminal identifier. Figure 3 Only some information corresponding to 2 terminal stations is shown in Figure (b) thereof, and the information corresponding to other terminal stations is similar.

[0091] Through Configuration Method 1, the management station can configure the indexes of the access uplink signal and the measurement uplink signal for each terminal station respectively, ensuring that each terminal station can flexibly use the uplink synchronization channel according to its own needs. This method not only improves the spectrum utilization rate, but also can use the uplink synchronization channel for full-bandwidth channel measurement when there is no terminal access, thereby optimizing the network performance.

[0092] Configuration Method 2: Since the uplink signal configuration information needs to be transmitted over the air interface, in order to save air interface resources, the management station can configure an index of an uplink signal and an index offset in the signal indication information of the target uplink signal, and the index of the other uplink signal is calculated by the already configured index value and the offset value.

[0093] Among them, the calculation method of the index of the other uplink signal can include but is not limited to: the index of the other uplink signal = the index of an already configured uplink signal + the index offset. The already configured uplink signal with an index can be the access uplink signal or the measurement uplink signal.

[0094] Among them, the number of terminal stations is at least one, and the signal indication information of the target uplink signal includes the following Case 1 or Case 2.

[0095] Case 1: The terminal identifier corresponding to each terminal station, the index of the access uplink signal, and the first index offset, where the first index offset is used to indicate the index offset of the measurement uplink signal relative to the access uplink signal.

[0096] Exemplarily, Figure 4 It is a schematic diagram of Configuration Method 2. As shown in Figure 4As shown in (a) therein, the number of terminal stations is one, and its corresponding terminal identifier is terminal identifier 1. The signal indication information of the target uplink signal includes: terminal identifier 1, the index of the access uplink signal corresponding to this terminal identifier 1, and the first index offset. Exemplarily, in this case, the index of the measured uplink signal = the index of the access uplink signal + the first index offset.

[0097] Exemplarily, such as Figure 4 As shown in (b) therein, the number of terminal stations is multiple. The signal indication information of the target uplink signal includes: terminal identifier 1, the index of the access uplink signal corresponding to this terminal identifier 1 and the first index offset; terminal identifier 2, the index of the access uplink signal corresponding to this terminal identifier 2 and the first index offset, and other respective terminal identifiers, and the index of the access uplink signal corresponding to each terminal identifier and the first index offset. Among them, for each terminal identifier, the index of the corresponding measured uplink signal can be calculated through the index of the access uplink signal and the first index offset. Figure 4 Only some information corresponding to 2 terminal stations is shown in (b) therein, and the information corresponding to other terminal stations is similar. Among them, the first index offset corresponding to each terminal identifier can be the same or different.

[0098] Case 2: The terminal identifier, the index of the measured uplink signal, and the second index offset corresponding to each terminal station. The second index offset is used to indicate the index offset of the access uplink signal relative to the measured uplink signal.

[0099] Exemplarily, such as Figure 4 As shown in (c) therein, the number of terminal stations is one, and its corresponding terminal identifier is terminal identifier 1. The signal indication information of the target uplink signal includes: terminal identifier 1, and the index of the measured uplink signal corresponding to this terminal identifier 1, and the second index offset. Exemplarily, in this case, the index of the access uplink signal = the index of the measured uplink signal + the second index offset.

[0100] Exemplarily, such as Figure 4 As shown in (d) therein, the number of terminal stations is multiple. The signal indication information of the target uplink signal includes: terminal identifier 1, the index of the measured uplink signal corresponding to this terminal identifier 1 and the second index offset; terminal identifier 2, the index of the measured uplink signal corresponding to this terminal identifier 2 and the second index offset, and other respective terminal identifiers, and the index of the measured uplink signal corresponding to each terminal identifier and the second index offset. Among them, for each terminal identifier, the index of the corresponding access uplink signal can be calculated through the index of the measured uplink signal and the second index offset. Figure 4Only some information corresponding to two terminal stations is shown in (d) of [the figure], and the information corresponding to other terminal stations is similar. Among them, the second index offset corresponding to each terminal identifier can be the same or different.

[0101] Configuration method two reduces the resource occupancy of the uplink signal configuration information in the air interface transmission by introducing an index offset. This method not only saves air interface resources, but also can flexibly calculate the index of another uplink signal, improving the flexibility and efficiency of the configuration. Especially in the case of a large number of terminal stations, configuration method two can significantly reduce the transmission volume of the configuration information and improve the overall performance of the system.

[0102] Configuration method three: Since the uplink signal configuration information needs to be transmitted in the air interface, in order to further save air interface resources, the management station can configure an uplink signal index in the signal indication information of the target uplink signal, and each terminal station shares an index offset; the index of another uplink signal is calculated through the shared index offset and the configured uplink signal index.

[0103] Exemplarily, the calculation method of the index of the above-mentioned another uplink signal may include but is not limited to: the index of another uplink signal = the configured uplink signal index + the index offset. The configured uplink signal with an index can be an access uplink signal or a measurement uplink signal.

[0104] Among them, the number of terminal stations is multiple, and the signal indication information of the target uplink signal includes the following case 3 or case 4.

[0105] Case 3: The third index offset, and the terminal identifier corresponding to each terminal station and the index of the access uplink signal. The third index offset is shared by multiple terminal stations and is used to indicate the index offset of the measurement uplink signal relative to the access uplink signal.

[0106] Exemplarily, Figure 5 is a schematic diagram of a configuration method three. As Figure 5 shown in (a) of [the figure], the number of terminal stations is multiple, and the signal indication information of the target uplink signal includes: the third index offset shared by multiple terminal stations; the terminal identifier 1 and the index of the access uplink signal corresponding to the terminal identifier 1; the terminal identifier 2 and the index of the access uplink signal corresponding to the terminal identifier 2; other each terminal identifier, and the index of the access uplink signal corresponding to each terminal identifier. Among them, the index of the measurement uplink signal of each terminal identifier can be determined based on the index of the access uplink signal of the terminal identifier and the third index offset.

[0107] Configuration method three improves the flexibility and scalability of the system while saving air interface resources by sharing the index offset, and is applicable to scenarios with a large number of terminal stations and complex resource allocation.

[0108] Case 4: The fourth index offset, as well as the terminal identifier corresponding to each terminal station and the index of the measured uplink signal. The fourth index offset is shared by multiple terminal stations and is used to indicate the index offset of the access uplink signal relative to the measured uplink signal.

[0109] Among them, the above period and period offset are used to solve the resource allocation problem when the uplink signal resources are limited or there are too many terminal stations. The management station configures a shared period for multiple terminal stations and can allocate different period offsets for each terminal station. In this way, the access uplink signal and the measured uplink signal of each terminal station will be sent at different time offset positions within the period, ensuring that the signals of multiple terminal stations do not conflict and the management station can accurately identify them.

[0110] Exemplarily, as Figure 5 shown in (b) of, the number of terminal stations is multiple, and the signal indication information of the target uplink signal includes: the fourth index offset shared by multiple terminal stations; the terminal identifier 1 and the index of the measured uplink signal corresponding to the terminal identifier 1; the terminal identifier 2 and the index of the measured uplink signal corresponding to the terminal identifier 2; other each terminal identifier, and the index of the measured uplink signal corresponding to each terminal identifier. Among them, the index of the access uplink signal of each terminal identifier can be determined based on the index of the measured uplink signal of the terminal identifier and the fourth index offset.

[0111] Configuration method four solves the resource allocation problem when the uplink signal resources are limited or the number of terminal stations is too large by introducing a period and a period offset. By allocating different period offsets for each terminal station, it ensures that multiple terminal stations can transmit uplink signals on different resources, avoiding signal conflicts and the problem that the management station cannot identify. This method not only improves the utilization rate of resources but also enhances the stability and reliability of the system.

[0112] In some embodiments, for the above configuration method one, configuration method two, and configuration method three, the target uplink signal is sent on each uplink synchronization channel.

[0113] Exemplarily, Figure 6 is a schematic diagram of sending on each uplink synchronization channel.

[0114] Figure 6 Shows the way of sending the target uplink signal on each uplink synchronization channel. By this way, the spectrum resources of the uplink synchronization channel can be fully utilized, avoiding resource idleness. Especially when there is no terminal access, the uplink synchronization channel can be used to send the measured uplink signal, thus realizing full-bandwidth channel measurement and significantly improving the spectrum utilization rate.

[0115] Configuration method 4: To address the situation of insufficient uplink signal resources or insufficient resources to be allocated among multiple terminal stations, or to address the problem that the management station cannot identify multiple uplink signals sent together, a period and a period offset are added during configuration so that multiple terminal stations transmit on different resources respectively. The access uplink signal and the measurement uplink signal of a terminal station share the same period and period offset configuration, and a terminal station will only send one type of uplink signal at a certain moment.

[0116] Among them, the number of terminal stations is multiple, and the signal indication information of the target uplink signal further includes, with respect to the above Configuration method 1, Configuration method 2, or Configuration method 3: a period corresponding to multiple terminal stations, and a period offset corresponding to each terminal station.

[0117] Exemplarily, Figure 7 is a schematic diagram of a Configuration method 4. As Figure 7 shown in (a) of Figure 3 , based on (b) of Figure 7 , a period is additionally configured; as Figure 4 shown in (b) of Figure 7 , based on (b) of Figure 4 , a period is additionally configured; as Figure 7 shown in (c) of Figure 5 , based on (d) of Figure 7 , a period is additionally configured; as Figure 5 shown in (d) of

[0118] In some embodiments, for the above Configuration method 4, the target uplink signal is sent on the radio frame corresponding to the target radio frame number, and the target radio frame number is determined by the period and the period offset.

[0119] Exemplarily, the above period can be a power of 2.

[0120] The relationship between the above target radio frame number, the period, and the period offset can be expressed as SFNmodT = offset. Where SFN represents the target radio frame number, T represents the period, and offset represents the period offset. Exemplarily, Figure 8 is a schematic diagram of sending on the radio frame corresponding to the target radio frame number. Figure 7 and Figure 8By introducing a period and a period offset, it is ensured that multiple terminal stations send uplink signals on different resources. This method effectively avoids the conflict problem caused by multiple terminal stations sending signals simultaneously, and improves the reliability of signal transmission and the identification efficiency of the management station.

[0121] In an exemplary embodiment, as Figure 9A shown, a flowchart of a method for transmitting an uplink signal is provided Figure 2 , taking this method applied to the Figure 1 uplink signal transmission system as an example for illustration, this method may include the following steps:

[0122] 91. The terminal station sends a target uplink signal to the management station on the uplink synchronization channel.

[0123] 92. The management station receives the target uplink signal sent by the terminal station on the uplink synchronization channel.

[0124] Among them, the above explanation for the target uplink signal can refer to the explanation in the above embodiment, and will not be elaborated here.

[0125] In the embodiment of the present application, the target uplink signal (access uplink signal, and / or, measurement uplink signal) can be transmitted on the uplink synchronization channel. In this way, when there is no terminal station accessing and no access uplink signal is sent, the uplink synchronization channel can also be used to send the measurement uplink signal, and when the measurement uplink signal is sent on the uplink synchronization channel, full-bandwidth channel measurement can be realized, thereby improving the spectrum utilization rate and realizing full-bandwidth channel measurement of the uplink.

[0126] In an exemplary embodiment, as Figure 9B shown, a flowchart of a method for transmitting an uplink signal is provided Figure 3 , taking this method applied to the Figure 1 uplink signal transmission system as an example for illustration, this method may include the following steps:

[0127] 901. The management station sends uplink signal configuration information to the terminal station.

[0128] For the description of the above step 901, reference can be made to the relevant description of the above step 201, and will not be elaborated here.

[0129] 902. The terminal station acquires the target uplink signal based on the signal indication information.

[0130] In the embodiment of the present application, after the terminal station receives the signal indication information of the target uplink signal sent by the management station, it can acquire the corresponding target uplink signal.

[0131] In some embodiments, in the embodiments of the present application, a target uplink signal may be generated according to the index of the target uplink signal. The target uplink signal may be generated based on the Zadoff-Chu sequence (abbreviated as ZC sequence), and the ZC sequence is a complex sequence widely used in wireless communication systems.

[0132] Exemplarily, the index of the access uplink signal and the index of the measurement uplink signal correspond to different ZC sequences respectively and , and may include but are not limited to the following methods:

[0133] Method 1:

[0134] (2)

[0135] (3)

[0136] Among them, and are the roots of the ZC sequences for access purposes (i.e., corresponding to the access uplink signal) and measurement purposes (i.e., corresponding to the measurement uplink signal) respectively, and the value range is ; is the ZC sequence length.

[0137] Method 2:

[0138] (4)

[0139] (5)

[0140] Among them, , is the root of the ZC sequence of the uplink signal, and the value range is ; is the cyclic shift capacity, and the value range is ; and are the cyclic shift indexes of the sequences for access purposes and measurement purposes respectively, and the value range is .

[0141] 903. The terminal station sends the target uplink signal to the management station on the uplink synchronization channel.

[0142] 904. The management station receives and processes the target uplink signal.

[0143] The above-mentioned management station receives the target uplink signal sent by the terminal station on the uplink synchronization channel.

[0144] Exemplarily, the management station knows the index of the access uplink signal and the index for measuring the uplink signal , and ZC sequences as shown in the above formulas (2) and (3) are obtained through these two indexes respectively and , because there is a low cross-correlation characteristic between ZC sequences with different roots, the management station can distinguish whether the uplink signal sent by the terminal station is for access or measurement purposes by calculating the correlation magnitudes between the received signal and the uplink signals corresponding to the ZC sequences with roots and respectively.

[0145] Exemplarily, the management station knows the index for the access uplink signal and the index for the measurement uplink signal and , and ZC sequences as shown in the above formulas (4) and (5) are obtained through these two indexes respectively. Because there is a zero-correlation characteristic between different cyclic shift sequence versions of ZC sequences with the same root, the management station can distinguish whether the uplink signal sent by the terminal station is for access or measurement purposes by calculating the position where the correlation peak of the received signal and the uplink signal corresponding to a certain root ZC sequence appears. Among them, the position where the correlation peak appears can be understood as that when the management station calculates the correlation between the received signal and the uplink signal corresponding to a specific ZC sequence, the obtained correlation value will have a peak at a certain position.

[0146] Among them, after receiving the target uplink signal, the management station obtains the information in the signal through demodulation and decoding. For the access uplink signal, the management station can be used for the synchronization and access of the terminal station; for the measurement uplink signal, the management station can be used for the measurement and optimization of channel state information.

[0147] In the above embodiments, by generating the target uplink signal based on the ZC sequence and using different root or cyclic shift indexes to distinguish the access-purpose and measurement-purpose uplink signals, efficient and flexible uplink signal configuration and transmission are achieved.

[0148] In some embodiments, the target uplink signal includes: the access uplink signal.

[0149] In some embodiments, after the terminal station sends the access uplink signal to the management station on the uplink synchronization channel, when it determines that the number of access failures is greater than the preset number, it can also re-receive the uplink signal configuration information sent by the management station; on the uplink synchronization channel, send a new access uplink signal to the management station; among them, the new access uplink signal is determined based on the re-received uplink signal configuration information.

[0150] In some embodiments, after the terminal station sends an access uplink signal to the management station on the uplink synchronization channel, it may further include: if the access fails once, re-receiving the uplink signal configuration information sent by the management station; on the uplink synchronization channel, sending a new access uplink signal to the management station; wherein, the new access uplink signal is determined based on the re-received uplink signal configuration information.

[0151] Among them, the above access failure includes but is not limited to the situations corresponding to the following conditions:

[0152] Access failure situation 1: Within a first preset duration after sending the access uplink signal, the terminal station does not receive the initial connection configuration message sent by the management station.

[0153] Among them, after the terminal station sends the access uplink signal, it fails to receive the initial connection configuration message of the management station within the first preset duration. This may be because interference occurs during the signal transmission process or the management station fails to correctly receive the signal. At this time, the terminal station needs to re-receive the uplink signal configuration information and send a new access uplink signal, or, when the number of failures is greater than the preset number, re-receive the uplink signal configuration information and send a new access uplink signal.

[0154] Access failure situation 2: Within a first preset duration after sending the access uplink signal, the terminal station receives the initial connection configuration message sent by the management station; sends an initial connection configuration response message to the management station, and within a second preset duration after sending the initial connection configuration response message, does not receive the target indication message, where the target indication message is used to indicate that the connection establishment is completed.

[0155] Among them, after the terminal station sends the initial connection configuration response message, it fails to receive the target indication message of the management station within the second preset duration. This may be because the management station fails to correctly process the response message or the network latency is relatively high. At this time, the terminal station also needs to re-send the access uplink signal, or, when the number of failures is greater than the preset number, re-receive the uplink signal configuration information and send a new access uplink signal.

[0156] The above first preset duration and second preset duration can be set according to actual requirements, and are not limited in the embodiments of the present disclosure.

[0157] In some embodiments, the above first preset duration and / or the above second preset duration can be configured by the management station for the terminal station. In some embodiments, the configuration information of the first preset duration and / or the above second preset duration can be carried in the above uplink signal configuration information and configured for the terminal station, or can be separately configured for the terminal station in other messages.

[0158] In some embodiments, the target uplink signal includes: a measurement uplink signal.

[0159] In some embodiments, after successfully accessing the management station, a measurement uplink signal is periodically sent to the management station on the uplink synchronization channel.

[0160] In an exemplary embodiment, as Figure 10 shown, a schematic diagram of a successful access process is provided. The method may include the following steps:

[0161] 1001. The terminal station sends an access uplink signal to the management station on the uplink synchronization channel.

[0162] 1002. The terminal station receives the initial connection configuration sent by the management station within a first preset duration after sending the access uplink signal.

[0163] After performing the above step 1001, if the initial connection configuration sent by the management station is not received within the first preset duration after sending the access uplink signal, it is considered that the access fails.

[0164] 1003. The terminal station sends an initial connection configuration response message to the management station.

[0165] Among them, the timing of the above first preset duration can be implemented by a timer. After the terminal sends the uplink signal for access, the timer T1 is started; if the initial connection configuration message is not received before T1 times out, it indicates that the current access fails, and the terminal will resend the access uplink signal. After receiving the initial connection configuration message before T1 times out, the timer T1 can be stopped, and an initial connection configuration response message is sent, and the timer T2 is started.

[0166] Access failure case 1 and access failure case 2 respectively correspond to different access failure scenarios. After access failure, the terminal station will receive the uplink signal configuration information sent by the management station again and send a new access uplink signal based on the new configuration information. This mechanism ensures that the terminal station can quickly recover and retry access after access failure, improving the reliability and robustness of the system.

[0167] The above initial connection configuration message can be sent by the management station and contains the configuration information required for the terminal station to access the network, such as resource allocation, synchronization parameters, etc.

[0168] 1004. The terminal station receives the target indication message sent by the management station within a second preset duration after sending the initial connection configuration response message.

[0169] Among them, the target indication message is used to indicate the completion of connection establishment. The above-mentioned second preset duration can be implemented by timer T2. The above-mentioned target indication message can be other messages except the connection rejection message and the connection release message. Exemplarily, the above-mentioned target indication message can include: connection establishment completion message, Service Capability Announcement, Security Handshake Success, etc.

[0170] When the target indication message is received before the timeout of T2, stop timer T2. At this time, it is considered that the access is successful; when the target indication message is not received before the timeout of T2, the timeout of the T2 timer indicates that the current access fails, and the terminal station will resend the access uplink signal.

[0171] The above-mentioned timers T1 and T2 are respectively used to monitor the access status of the terminal station at different stages. T1 is used to monitor the reception of the initial connection configuration message, while T2 is used to monitor the reception of the target indication message. Through the timer mechanism, the terminal station can timely detect access failures and take corresponding recovery measures, thereby improving the efficiency and reliability of the access process.

[0172] In some embodiments, after successfully accessing the management station, the measurement uplink signal is periodically sent to the management station on the uplink synchronization channel.

[0173] Exemplarily, as Figure 11 shown, a schematic diagram of the process of periodically sending the measurement uplink signal after successful access is provided. Based on the above Figure 10 , the following steps can be executed after step 1004:

[0174] 1005. The terminal station periodically sends the measurement uplink signal to the management station.

[0175] The main purpose of the above-mentioned periodic sending of the measurement uplink signal is to provide real-time channel state information for the management station to optimize network performance. Through periodic measurement, the management station can dynamically adjust parameters such as resource allocation and signal power, thereby improving transmission efficiency and network stability.

[0176] In some embodiments, after the terminal station initiates access to the management station, the measurement uplink signal is periodically sent to the management station on the uplink synchronization channel.

[0177] In some embodiments, the terminal station sends an access uplink signal to the management station on the uplink synchronization channel; if the initial connection configuration sent by the management station is received within the first preset duration after sending the access uplink signal, the measurement uplink signal is sent periodically.

[0178] In some embodiments, if the initial connection configuration sent by the management station is received within the first preset duration after the access uplink signal is sent, an initial connection configuration response message is sent to the management station; if the target indication message is received within the second preset duration after the initial connection configuration response message is sent, a measurement uplink signal is sent to the management station on the uplink synchronization channel. The target indication message is used to indicate that the connection establishment is completed.

[0179] In an exemplary embodiment, as Figure 12 shown, a schematic diagram of a process for periodically sending a measurement uplink signal after initiating access is provided. The method may include the following steps:

[0180] 1201. The terminal station sends an access uplink signal to the management station on the uplink synchronization channel.

[0181] 1202. The terminal station receives the initial connection configuration sent by the management station within the first preset duration after sending the access uplink signal.

[0182] Among them, the above first preset duration can be timed by the above timer T1.

[0183] 1203. The terminal station periodically sends a measurement uplink signal to the management station.

[0184] 1204. The terminal station sends an initial connection configuration response message to the management station.

[0185] 1205. The terminal station receives the target indication message sent by the management station within the second preset duration after sending the initial connection configuration response message.

[0186] The above second preset duration can be timed by the above timer T2.

[0187] 1206. The terminal station periodically sends a measurement uplink signal to the management station.

[0188] In the above process of periodically sending a measurement uplink signal after initiating access, first, the terminal station first sends an access uplink signal and obtains the initial connection configuration within the first preset duration, ensuring the timeliness and orderliness of connection establishment; then, the terminal station periodically sends a measurement uplink signal, which helps the management station continuously obtain relevant information of the terminal station for more accurate management and resource allocation; the terminal station sends an initial connection configuration response message, enabling the management station to confirm that the configuration has been received and enhancing the reliability of communication; receiving the target indication message within the second preset duration after sending this response message further clarifies the subsequent working direction of the terminal station; and then periodically sending a measurement uplink signal again to continuously provide necessary information for the management station. The entire process improves the stability, reliability, and management efficiency of communication through reasonable steps and time settings.

[0189] Exemplarily, Figure 13 This is a flowchart for the case of stopping sending measurement uplink signals. The terminal station sends an access uplink signal to the management station and receives the initial connection configuration before the timer T1 times out. Then, it can periodically send measurement uplink signals to the management station and send an initial connection configuration response to the management station. As Figure 13 shown in (a) of [[ID=]], after sending the initial connection configuration response to the management station, if the target indication message sent by the management station is not received before the T2 timer times out, the measurement uplink signal for measurement is stopped at this time. Or, as Figure 13 shown in (b) of [[ID=]], after sending the initial connection configuration response to the management station, when a connection rejection message or a connection release message is received, the measurement uplink signal for measurement is stopped.

[0190] In the above case of stopping sending measurement uplink signals, if the target indication message from the management station is not received before the T2 timer times out after sending the initial connection configuration response, the terminal station will stop sending measurement uplink signals. If a connection rejection or connection release message is received after sending the initial connection configuration response, the terminal station will also stop sending measurement uplink signals. This mechanism effectively manages network resources, avoids unnecessary signal transmission, thereby reducing network congestion and energy consumption, and improving the overall efficiency and reliability of the system.

[0191] In some embodiments, only the access uplink signal is received and processed before receiving the initial connection configuration response. After receiving the initial connection configuration response, two types of uplink signals can be received and processed, namely the access uplink signal or the measurement uplink signal.

[0192] In some embodiments, the access uplink signal can be received and then the initial connection configuration message is sent to the terminal station. After receiving the initial connection configuration response message sent by the terminal station, the access uplink signal or the measurement uplink signal is received and processed.

[0193] Exemplarily, Figure 14 This is a flowchart for receiving and processing uplink signals. As Figure 14 shown, after the management station sends the uplink signal configuration information to the terminal station, it starts to receive the access uplink signal, sends the initial connection configuration to the terminal station after receiving the access uplink signal, and starts to receive the access uplink signal or the measurement uplink signal after successfully receiving the initial connection configuration response sent by the terminal station and verifying the identity of the terminal station. That is to say, at this stage, the management station can allow the reception of two types of uplink signals, but only one type of uplink signal will be received at the same time.

[0194] In Figure 14In the shown process schematic diagram, during the process of the management station receiving and processing the upstream signal, a phased strategy is adopted, significantly improving the flexibility and efficiency of signal processing. In the initial stage, the management station only receives and processes the access upstream signal to ensure that the basic connection requests of the terminal stations are responded to in a timely manner. Once the management station sends an initial connection configuration message to the terminal station and successfully receives the initial connection configuration response from the terminal station, the management station enters the second stage, at which time it can receive and process two types of upstream signals (access upstream signal or measurement upstream signal). This phased processing mechanism not only optimizes resource allocation but also enhances the adaptability of the system, enabling the management station to dynamically adjust the signal reception strategy according to the network status and the requirements of the terminal stations. In addition, by processing only one upstream signal at the same time, signal conflicts and resource competition are avoided, further improving the stability and reliability of the system. Overall, this design effectively balances the network load, improves communication efficiency, and provides higher flexibility and scalability for network management.

[0195] It should be understood that although each step in the flowcharts involved in the above embodiments is shown in sequence according to the indication of the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless there is a clear indication in this article, the execution of these steps has no strict order limit, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same moment, but can be executed at different moments, and the execution order of these steps or stages is not necessarily sequential, but can be executed alternately or in turn with at least a part of other steps or steps or stages in other steps.
