Timing Advance (TA): the parameter is used for representing the timing deviation of the data sent by the terminal equipment and received by the network equipment, and the physical meaning of the parameter refers to the back-and-forth time delay of the terminal equipment and the network equipment.

Currently, a terminal device needs to perform strict clock synchronization with a network, for example, as shown in fig. 1, fig. 1 provides for an embodiment of the present applicationA schematic flow diagram of clock synchronization is shown in the figure, in a scheme that a 5G network is used as a bridge to synchronize an external device connected to a 5G terminal device with a clock in the external network, the external network clock can be synchronized with the external device connected to the terminal by sending a synchronization signaling (sync message), firstly, a Time Sensitive Network (TSN) node at the right end needs to send the clock synchronization signaling to a 5GS edge adapter, and the 5GS edge adapter uses the current Time of the 5G internal clock to carry a 5GS receiving point timestamp TSi on the clock synchronization signaling. Then, the synchronization signaling is transmitted from the User Plane Function (User Plane Function, UPF) to the edge adapter of the User end via the base station, and the edge adapter of the User end carries a 5GS issue point timestamp TSe, it can be seen that the transmission delay Time of the signaling in the 5G interior can be calculated as TSe-TSi, finally, the 5G terminal sends a Generalized Precision Time Protocol (gPTP) synchronization message with a 5G interior transmission processing duration to the left TSN node to complete clock synchronization, and the current Time of the left TSN node can be represented as T_left＝T _GM,right+TSe-TSi+D ₂+D ₁Wherein, T_GM,rightIs the time point, D, sent by the right TSN node₂Propagation delay from the right-hand TSN node to the customer-side 5GS edge adapter, D₁For the propagation delay from the left-end TSN node to the 5GS edge adapter, it can be seen that the end device needs to have strict clock synchronization with the network device so that TSi and TSe are bound to the same clock.

Referring to fig. 3, fig. 3 is a flowchart illustrating a method for adjusting a timing advance threshold according to an embodiment of the present application, where the method is applied to the wireless communication system shown in fig. 2, and as shown in the figure, the method includes the following steps:

s310, the terminal equipment sends first reference information.

Wherein the first reference information comprises the wireless signal quality and/or the geographical position measured by the terminal device.

Specifically, when the terminal device has a positioning capability or a capability of acquiring a current geographic location, the first reference information may include a wireless signal quality and a geographic location measured by the terminal device, or the first reference information may include a wireless signal quality or a geographic location measured by the terminal device; the first reference information may comprise radio signal quality measured by the terminal device when the terminal device does not have positioning capability or capability to obtain the current geographical position.

Further, the wireless signal quality may include at least one of: cell (cell) Reference Signal Received Power (RSRP), cell Reference Signal Received Quality (RSRQ), cell Signal to Interference plus Noise Ratio (SINR), cell Received Signal Strength Indicator (RSSI), Synchronization Signal Block (SSB) RSRP, SSB RSRQ, SSB SINR, SSB RSSI, Channel State Information Reference Signal (CSI-RS) RSRP, CSI-RS PQ, CSI-RS and CSI-RS RSSI.

In an implementation manner of the embodiment of the present application, the method further includes: the network equipment sends a second wireless signal quality threshold, the terminal equipment receives the second wireless signal quality threshold, and the second wireless signal quality threshold is used for the terminal equipment to determine whether to acquire the timing advance.

Although the terminal device may acquire the network clock through unicast signaling or broadcast signaling sent by the network to perform clock synchronization, in order to acquire better synchronization performance, the terminal device and/or the network device may need to eliminate synchronization errors caused by propagation path delay by acquiring a timing advance. If the distance between the terminal equipment and the network equipment is short, the terminal equipment does not need to be synchronized; if the terminal device is far from the network, the delay of the propagation path needs to be compensated. However, for a terminal device closer to the network device, that is, the terminal device is in a coverage area where the network device does not need to compensate the propagation delay, the terminal device may also initiate a random access procedure to acquire a new timing advance, thereby causing additional air interface overhead. In the embodiment of the present application, the network device may send the wireless signal quality threshold to the terminal device, so that the terminal device obtains the new timing advance only when the wireless signal quality measured by the terminal device is lower than the configured wireless signal quality threshold, thereby saving air interface overhead.

The second Radio signal quality threshold may be carried in Radio Resource Control (RRC) signaling, MAC Control Element (MAC CE) signaling, or a broadcast message.

It should be noted that the RRC signaling may include, but is not limited to, any one of an RRC Release message, an RRC connection reconfiguration message, an RRC connection reestablishment message, an RRC connection setup message, an RRC connection resume message, or other RRC messages.

Further, the second wireless signal quality threshold comprises at least one of: cell RSRP, cell RSRQ, cell SINR, cell RSSI, SSB RSRP, SSB RSRQ, SSB SINR, SSB RSSI, CSI-RS RSRP, CSI-RS RSPQ, CSI-RS SINR, and CSI-RS RSSI.

It should be noted that the first wireless signal quality threshold and the second wireless signal quality threshold are used for the terminal device to distinguish whether it is in a coverage area where the network device does not need to compensate the propagation delay. That is, the terminal device determines whether it is in a coverage area where the base station does not need to compensate for the propagation delay by comparing the wireless signal quality measured by the terminal device with the first wireless signal quality or the second wireless signal quality, and if the terminal device is in the coverage area where the base station needs to compensate for the propagation delay, the terminal device reacquires a new timing advance, and if the terminal device is not in the coverage area where the base station needs to compensate for the propagation delay, the terminal device does not need to acquire the new timing advance.

It should be noted that the content included in the wireless signal quality measured by the terminal device in the first reference information includes at least one of the content included in the second wireless signal quality threshold received by the terminal device, for example, when only cell RSRP is included in the second wireless signal quality threshold, the wireless signal quality measured by the terminal device may include cell RSRP, when cell RSRP and SSB RSRP are included in the second wireless signal quality threshold, the wireless signal quality measured by the terminal device may include cell RSRP, and when cell RSRP, CSI-RS RSRP and SSB RSRP are included in the second wireless signal quality threshold, the wireless signal quality measured by the terminal device may include cell RSRP and SSB RSRP.

In an implementation manner of the embodiment of the present application, the sending, by the terminal device, the first reference information includes:

and the terminal equipment sends the first reference information under the condition that the wireless signal quality measured by the terminal equipment is greater than or equal to the second wireless signal quality threshold value and the terminal equipment and the network equipment are not in clock synchronization.

After receiving the second wireless signal quality threshold, the terminal device compares the second wireless signal quality threshold with the wireless signal quality currently measured by the terminal device, and when the wireless signal quality measured by the terminal device is greater than or equal to the second wireless signal quality threshold, that is, when the terminal device is in a coverage area where the network device does not need to compensate propagation delay, the terminal device may not take action to obtain the timing advance, but in this case, because the second wireless signal quality threshold set by the network device is not accurate enough, for example, when the second wireless signal quality threshold is set too low, the terminal device may not start an action of obtaining the latest timing advance due to being far away from the base station, so that the clocks between the terminal device and the base station are not synchronized, for example, as shown in fig. 4, a coverage area where the base station does not need to compensate propagation delay is in a dotted circle area in the figure, the area between the solid line circle and the dotted line circle is a coverage area of the base station, which needs to compensate propagation delay, assuming that the RSRP of the cell in the second radio signal quality threshold is set to-60 dBm, when the terminal device moves from the center of the base station to the edge, i.e. the terminal device moves from the dotted line area range to the solid line area range in the figure, when the terminal device moves to the area between the solid line circle and the dotted line circle, the RSRP of the cell of the radio signal quality threshold measured by the terminal device is-56 dBm, which is greater than the second radio signal quality threshold, the terminal device does not need to take action to obtain a new timing advance, but the terminal device is in the coverage area of the base station, which needs to compensate propagation delay, so that the terminal device has a serious clock desynchronization problem, and therefore, the terminal device needs to report first reference information to the network to accurately adjust the radio signal quality threshold, to achieve clock synchronization between it and the network device.

In an implementation manner of the embodiment of the present application, the method further includes: and under the condition that the wireless signal quality measured by the terminal equipment is less than the second wireless signal quality threshold, the terminal equipment acquires the timing advance.

Specifically, when the quality of the wireless signal measured by the terminal device is smaller than the second wireless signal quality threshold, clock synchronization occurs between the terminal device and the network device, and the terminal device needs to acquire a new timing advance to achieve clock synchronization between the terminal device and the network device.

In another implementation manner of the embodiment of the present application, the method further includes: and when the wireless signal quality measured by the terminal equipment is greater than or equal to the second wireless signal quality threshold and the terminal equipment is not synchronous with the clock of the network equipment and/or other terminal equipment, the terminal equipment acquires the timing advance.

Specifically, when the second wireless signal quality threshold set by the network device is inaccurate, for example, the second wireless signal quality threshold is too low, and when the wireless signal quality measured by the terminal device is greater than or equal to the second wireless signal quality threshold, clock asynchronization may occur between the terminal device and the network device, and at this time, the terminal device also needs to acquire a new timing advance to implement clock synchronization between the terminal device and the network device.

Further, in the communication process between the terminal device and the terminal device using the network as a bridge, in order to obtain better synchronization performance, the terminal or the network device base station may need to eliminate synchronization errors caused by propagation path delay by obtaining the timing advance. If the distance between the terminal and the base station is short, the terminal equipment does not need to be synchronized; if the distance between the terminal and the network equipment is far, propagation path compensation is needed. When the terminal device and other terminal devices are out of clock synchronization, the terminal device needs to report the first reference information to the network to accurately adjust the wireless signal quality threshold, so as to implement clock synchronization between the terminal device and other terminal devices.

Optionally, the acquiring, by the terminal device, the timing advance includes: the terminal equipment sends a random access lead code to the network equipment and receives a random access response from the network equipment, wherein the random access response carries the timing advance; alternatively, the first and second electrodes may be,

the terminal device sends uplink data or auxiliary signals (secondary signals) to the network device, and receives timing advance information sent by the network device.

In this embodiment, due to the mobility of the terminal device, the clock synchronization relationship between the terminal device and the network device may be changed, and the terminal device needs to adjust the timing advance to maintain clock synchronization, that is, needs to acquire a new timing advance. Specifically, the terminal device may initiate a random access procedure to the network device to obtain a new timing advance, for example, the terminal device sends a random access preamble to the network device, and the network device calculates a new timing advance according to a sending time and a receiving time of the random access preamble, and sends the new timing advance to the terminal device in a random access response; the terminal device may also send uplink data or an auxiliary signal to the network device to obtain the timing advance, for example, the terminal device sends the uplink data or the auxiliary signal to the network device, and the network device calculates a new timing advance according to the sending time and the receiving time of the uplink data or the auxiliary signal and sends the new timing advance to the terminal device.

In an implementation manner of the embodiment of the present application, the method further includes: the network device sends a first message, and the terminal device receives the first message, wherein the first message is used for inquiring about the availability (availabilities) of the first reference information of the terminal device.

Optionally, the first message may be an information request (information request) message, and the network device may query, by sending the information request message, the terminal device whether there is the first reference information to report.

Further, the first reference information may be a response or report message of the terminal device to the received information request message.

In practical application, because of the complexity of a propagation environment, a wireless signal quality threshold set by a network device according to experience may not be accurate enough, and when the wireless signal quality threshold is set too low, a terminal device may be far away from the network device and cannot enable the terminal device to start an action of acquiring a latest timing advance, so that severe asynchronization between the terminal device and a network is caused, and further, a severe Industrial Internet of Things (IIOT) application problem, for example, an asynchronous action between a robot arm and a pipeline may be caused; when the wireless signal quality threshold is set too high, the terminal device may be closer to the network device and frequently take action to obtain unnecessary timing advance, thereby causing additional air interface overhead. Therefore, in order to set an accurate wireless signal quality threshold, the network device may send an information request message to the terminal device to instruct the terminal device to report to obtain the wireless signal quality and/or the geographic location measured by the current terminal device, so that the network device accurately adjusts the wireless signal quality threshold according to the reported information, thereby ensuring clock synchronization between the terminal device and the network device.

In an implementation manner of the embodiment of the present application, the method further includes: the terminal device sends a second message, the network device receives the second message, and the second message is used for indicating the network device to send the first message and/or reporting the condition that the terminal device and the network device and/or other terminals are out of clock synchronization.

When the wireless signal quality measured by the terminal device is less than the second wireless signal quality threshold, that is, when a problem of clock asynchronism between the terminal device and the network device and/or other terminal devices occurs during the moving process of the terminal device, the terminal device may send a second message to the network device, where the second message may specifically carry information of clock asynchronism between the terminal device and the network device, so as to report the problem of clock asynchronism to the network device; when the wireless signal quality measured by the terminal device is greater than or equal to the second wireless signal quality threshold and the terminal device is out of clock synchronization with the network device and/or other terminal devices, the terminal device may send a second message to the network device to instruct the network device to send the first message. After receiving the second message, the network device may send an information request message to the terminal device to query whether the terminal device has the first reference information to report.

S320, the network equipment receives the first reference information.

S330, the network equipment sends the first wireless signal quality threshold value to the terminal equipment.

Wherein the first radio signal quality threshold is carried in RRC signaling, MAC CE signaling or broadcast messages.

Further, the first wireless signal quality threshold comprises at least one of: cell RSRP, cell RSRQ, cell SINR, cell RSSI, SSB RSRP, SSB RSRQ, SSB SINR, SSB RSSI, CSI-RS RSRP, CSI-RS RSPQ, CSI-RS SINR, and CSI-RS RSSI.

Wherein the first wireless signal quality threshold is determined by the network device based on the first reference information.

After receiving the first reference information, the network device may determine the first wireless signal quality threshold according to the wireless signal quality and/or the geographic location and/or the second wireless signal quality threshold measured by the terminal device.

Specifically, the first reference information includes a wireless signal quality threshold measured by the terminal device, and when the value of the wireless signal quality measured by the terminal device is greater than or equal to the second wireless signal quality threshold, the network device may set the first wireless signal quality threshold to be higher than the value of the wireless signal quality measured by the terminal device; the network device may set the first wireless signal quality threshold to be lower than the value of the wireless signal quality measured by the terminal device when the value of the wireless signal quality measured by the terminal device is less than the second wireless signal quality threshold. For example, assuming that the first reference information includes a signal quality threshold measured by the terminal device, the value of cell RSRP in the radio signal quality measured by the terminal device is-60 dBm, and the value of cell RSRP included in the second radio signal quality threshold is-57 dBm, the network device may set the cell RSRP in the first radio signal quality threshold to-55 dBm according to the radio signal quality measured by the terminal device.

Specifically, when the first reference information includes a geographical location, the network device may determine, according to the geographical location, a distance between the current terminal device and the network device, which does not need to compensate for the propagation delay area, and set the first wireless signal quality threshold according to the distance and the second wireless signal quality threshold. For example, assuming that the first reference information includes a geographical location of the terminal device, and a value of cell RSRP included in the second radio signal quality threshold is-57 dBm, the network device may determine that the current terminal device is 100m away from the base station without compensating for the propagation delay area according to the geographical location, and the network device may set the cell RSRP included in the first radio signal quality threshold to-55 dBm according to the distance.

Further, when the first reference information includes the wireless signal quality and the geographic position measured by the terminal device, the network device may determine, according to the geographic position, a distance between the current terminal device and the network device, where the distance does not need to compensate for the propagation delay area, and when the value of the wireless signal quality measured by the terminal device is greater than or equal to the second wireless signal quality threshold, the network device may set the first wireless signal quality threshold to be higher than the value of the wireless signal quality measured by the terminal device in combination with the distance; the network device may set the first wireless signal quality threshold lower than the value of the wireless signal quality measured by the terminal device in connection with the distance when the value of the wireless signal quality measured by the terminal device is less than the second wireless signal quality threshold. For example, assuming that the first reference information includes a signal quality threshold and a geographical location measured by the terminal device, a cell RSRP value in the wireless signal quality measured by the terminal device is-60 dBm, a cell RSRP value included in the second wireless signal quality threshold is-57 dBm, the network device determines that the current terminal device is 100 dBm from the base station without compensating for the propagation delay area according to the geographical location, and the network device may set the first wireless signal quality threshold to-55 dBm according to the distance.

It should be noted that, the content of the first wireless signal quality threshold and the content of the second wireless signal quality threshold may be the same, for example, the first wireless signal quality threshold may include a cell RSRP and an SSB RSRP, the second wireless signal quality threshold may include a cell RSRP and an SSB RSRP, and the content of the first wireless signal quality threshold and the content of the second wireless signal quality threshold may also be different, for example, the first wireless signal quality threshold may include a cell RSRP and an SSB RSRP, and the second wireless signal quality threshold may include a cell RSRP, an SSB RSRP, and a CSI-RS RSRP, which is not limited in this embodiment.
