Detailed Description

The terminology used in the description section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application. The terms "first," "second," "third," and "fourth" in the description and claims of this application and in the drawings are used for distinguishing between different objects and not for describing a particular sequential order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion.

In the following, some terms in the embodiments of the present application are explained for easy understanding by those skilled in the art.

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

At present, a terminal device needs to be strictly clock-synchronized with a network, for example, as shown in fig. 1, fig. 1 is a schematic flow chart of clock synchronization provided in an embodiment of the present application, as shown in fig. 1, in a scheme that a 5G network is used as a bridge to synchronize an external device connected to the 5G terminal device with a clock in the external network, an external network clock may be synchronized with the external device connected to the terminal by sending a synchronization signaling (sync message), first, a time sensitive network (Time Sensitive Networking, 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. Thereafter, the synchronization signaling is transmitted from the user plane function ((User Plane Function, UPF) to the edge adapter of the user side via the base station, and the edge adapter of the user side carries a 5GS send-out point timestamp TSe, it can be seen that the signaling transmission delay time in the 5G can be calculated as TSe-TSi, finally, the 5G terminal sends a generalized accurate clock protocol (Generalized Precision Time Protocol, gPTP) synchronization message with a 5G internal transmission processing duration to the left TSN node, completing clock synchronization, and the current time of the left TSN node can be expressed as follows The method is shown as follows: t (T) _left ＝T _GM，right +TSe-TSi+D ₂ +D ₁ Wherein T is _GM，right D, a time point transmitted by the right-end TSN node ₂ Propagation delay from right TSN node to user 5GS edge adapter, D ₁ Propagation delay for the left-hand TSN node to the 5GS edge adapter, whereby it is seen that the end device needs to be strictly clock synchronized with the network device in order for TSi and TSe to be bound to the same clock.

All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Referring to fig. 3, fig. 3 is a flowchart of a method for adjusting a threshold of a timing advance 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 drawing, the method includes the following steps:

s310, the terminal equipment sends first reference information.

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

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

Further, the wireless signal quality may include at least one of: cell reference signal received power (Reference Signal Received Power, RSRP), cell reference signal received quality (Reference Signal Received Quality, RSRQ), cell signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR), cell received signal strength indication (Received Signal Strength Indicator, RSSI), synchronization signal block (Synchronization Signal Block, SSB) RSRP, SSB RSRQ, SSB SINR, SSB RSSI, channel state information reference signal (Channel State Information reference signals, CSI-RS) RSRP, CSI-RS RSPQ, CSI-RS SINR, and CSI-RS RSSI.

In an implementation manner of an embodiment of the present application, the method further includes: the network device sends a second wireless signal quality threshold, the terminal device receives the second wireless signal quality threshold, and the second wireless signal quality threshold is used for the terminal device 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 relatively short, the terminal equipment can be not required to be synchronized; if the terminal device is far from the network, the delay of the propagation path needs to be compensated. However, for terminal devices closer to the network device, i.e., the terminal device is in a coverage area where the network device does not need to compensate for the propagation delay, the terminal device may also initiate a random access procedure to acquire a new timing advance, thereby causing additional overhead. In the embodiment of the application, the network device may send the wireless signal quality threshold to the terminal device, so that the terminal device may acquire the new timing advance only when the measured wireless signal quality is lower than the configured wireless signal quality threshold, thereby saving air interface overhead.

Wherein the second radio signal quality threshold may be carried in radio resource control (Radio Resource Control, RRC) signaling, MAC control element (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 of RRC Release message, RRC connection reconfiguration message, RRC connection reestablishment message, RRC connection setup message, RRC connection resume message, or other RRC message.

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 distinguishing whether the terminal device is in a coverage area where the network device does not need to compensate for 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 measured wireless signal quality with the first wireless signal quality or the second wireless signal quality, and if the terminal device is in a coverage area where the base station needs to compensate for the propagation delay, the terminal device reacquires the new timing advance, and if the terminal device is not in a coverage area where the base station needs to compensate for the propagation delay, it is not necessary to acquire the new timing advance.

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

In an implementation manner of the embodiment of the present application, the sending, by the terminal device, 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 larger than or equal to the second wireless signal quality threshold value and the clock of the terminal equipment and the clock of the network equipment are not synchronous.

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 in the case that 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 for propagation delay, the terminal device may need to take no action to acquire 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 the action of acquiring the latest timing advance due to being far away from the base station, resulting in that clocks between the terminal device and the base station are not synchronized, for example, as shown in fig. 4, in the figure, the coverage area of the base station needing no propagation delay compensation is shown in the area of the dotted line circle, the coverage area between the solid line circle and the dotted line circle is the coverage area of the base station needing propagation delay compensation, the area RSRP of the cell is-60 dBm, in the process of moving the terminal equipment from the center of the base station to the edge, namely, the process of moving the terminal equipment from the area of the dotted line to the area of the solid line in the figure, when the terminal equipment moves to the area between the solid line circle and the dotted line circle, the area RSRP of the cell of the wireless signal quality threshold measured by the terminal equipment is-56 dBm, which is larger than the second wireless signal quality threshold, the terminal equipment needs no action to acquire a new timing advance, but at the moment, the terminal equipment is in the coverage area of the base station needing propagation delay compensation, so that serious clock dyssynchrony problem occurs to the terminal equipment, therefore, the terminal device needs to report the first reference information to the network to accurately adjust the wireless signal quality threshold so as to realize clock synchronization between the terminal device and the network device.

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

Specifically, in the case that the wireless signal quality measured by the terminal device is smaller than the second wireless signal quality threshold, clock dyssynchrony occurs between the terminal device and the network device, and the terminal device is required to acquire a new timing advance to realize 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 under the condition that the wireless signal quality measured by the terminal equipment is larger than or equal to the second wireless signal quality threshold value and the clock of the terminal equipment is not synchronous with that 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 in the case that 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 achieve clock synchronization between the terminal device and the network device.

Further, in the communication process between the terminal devices 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 timing advance. If the distance between the terminal and the base station is relatively short, the terminal equipment can be free from synchronization; if the terminal is far from the network device, propagation path compensation is required. When the clock is not synchronous with other terminal equipment, the terminal equipment needs to report the first reference information to the network to accurately adjust the wireless signal quality threshold value so as to realize the clock synchronization with other terminal equipment.

Optionally, the terminal device obtaining the timing advance includes: the terminal equipment sends a random access preamble to the network equipment and receives a random access response from the network equipment, wherein the random access response carries the timing advance; or,

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

In this embodiment, due to mobility of the terminal device, a clock synchronization relationship between the terminal device and the network device may be changed, and the terminal device needs to adjust a 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 the new timing advance according to the sending time and the receiving time of the random access preamble, and carries the new timing advance in a random access response and sends the new timing advance to the terminal device; the terminal device may also send uplink data or an auxiliary signal to the network device to obtain a timing advance, for example, the terminal device sends uplink data or an 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 an embodiment of the present application, the method further includes: the network device sends a first message, and the terminal device receives the first message, where the first message is used to query the terminal device for availability (availability) of the first reference information.

Alternatively, the first message may be an information request (information request) message, and the network device may query the terminal device for the first reference information by sending the information request message to report.

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

In practical applications, because the propagation environment is complex, the wireless signal quality threshold set by the network device according to experience may not be accurate enough, when the wireless signal quality threshold is set too low, the terminal device may be far away from the network device and cannot enable the terminal device to start the action of acquiring the latest timing advance, so that serious dyssynchrony between the terminal device and the network is caused, and further serious industrial internet of things (Industrial Internet of Things, IIOT) application problems, such as the action dyssynchrony between the robot arm and the pipeline, may be caused; when the wireless signal quality threshold is set too high, the terminal device may be relatively close to the network device and frequently take action to acquire unnecessary timing advance, resulting in 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 geographical position 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 an embodiment of the present application, the method further includes: the terminal equipment sends a second message, the network equipment receives the second message, and the second message is used for indicating the network equipment to send the first message and/or reporting that the terminal equipment and the network equipment and/or other terminals are out of clock.

When the wireless signal quality measured by the terminal equipment is smaller than the second wireless signal quality threshold, namely, when the problem of clock asynchronism with the network equipment and/or other terminal equipment occurs in the moving process of the terminal equipment, the terminal equipment can send a second message to the network equipment, and the second message can specifically carry the information of clock asynchronism between the terminal equipment and the network equipment so as to report the problem of clock asynchronism to the network equipment; 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 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 for reporting.

S320, the network equipment receives the first reference information.

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

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

Further, the first wireless signal quality threshold includes 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 geographical position measured by the terminal device and/or the second wireless signal quality threshold.

Specifically, the first reference information includes a wireless signal quality threshold measured by the terminal device, and when a value of the wireless signal quality measured by the terminal device is greater than or equal to a 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 smaller 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, a value of a cell RSRP in the radio signal quality measured by the terminal device is-60 dBm, a value of a 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 where the network device does not need to compensate for a 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, the value of the 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 from the base station without compensating for the propagation delay region according to the geographical location, and the network device may set the cell RSRP 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 measured by the terminal device and the geographical location, the network device may determine that the current distance between the terminal device and the network device does not need to compensate for the propagation delay area according to the geographical location, 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; when the value of the wireless signal quality measured by the terminal device is smaller than the second wireless signal quality threshold, 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 in conjunction with the distance. For example, assuming that the first reference information includes a signal quality threshold measured by the terminal device and a geographical location, a value of a cell RSRP in a radio signal quality measured by the terminal device is-60 dBm, a value of a cell RSRP included in the second radio signal quality threshold is-57 dBm, the network device determines that the current terminal device is 100m from the base station without compensating for a propagation delay area according to the geographical location, and the network device may set the first radio 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 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, the content of the first wireless signal quality threshold and the second wireless signal quality threshold may 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 the embodiment of the present application.
