Information transmission method, terminal device and network side device

[0001] Cross-reference to Related Applications

[0002] This application claims priority to Chinese Patent Application No. 201910082036.1 filed in China on January 28, 2019, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present disclosure relates to the field of communication technology, and in particular, to an information transmission method, a terminal device and a network side device. BACKGROUND

[0004] In a mobile communication system, for example, a Long Term Evolution (LTE) system, a network side can send a system message (for example, a System Information Block (SIB) 16 (also referred to as SIB16)) to a User Equipment (UE) (also referred to as a terminal device), and the system message can indicate a reference time (for example, Treference).

[0005] When the network side provides the UE with the reference time, due to the influence of air interface transmission delay, the time point at which the UE receives the reference time provided by the network side device is inconsistent with the time point at which the network side device actually sends the reference time. In the case where the UE needs a reference time with high precision (for example, 1us (i.e., microsecond)), the UE can acquire an uplink timing advance (Timing Advance, TA) by initiating a non-contention random access process, and through the uplink timing advance, the UE can correct the received reference time (for example, TA / 2 is the air interface transmission delay).

[0006] In the related art, since the non-contention random access is initiated by the network side, however, the network side does not know when the UE needs to acquire the above-mentioned reference time, thereby causing the network side to be unable to timely trigger the non-contention random access, and further causing the UE to be unable to timely correct the received reference time, resulting in low accuracy of the reference time.

[0007] SUMMARY

[0008] Embodiments of the present disclosure provide an information transmission method, a terminal device and a network side device, which can solve the problem in the related art that the network side is unable to timely trigger a non-contention random access to correct a reference time due to the network side being unable to timely know the reference time needed to be acquired by a terminal device.

[0036] For the convenience of description, some terms related to the embodiments of the present disclosure are described below.

[0037] I. Reference time

[0038] In a mobile communication system, for example, a Long Term Evolution (LTE) system, a network side can send a system message (for example, a System Information Block (SIB) 16 (also referred to as SIB16)) to a user equipment (UE) (also referred to as a terminal device), and the system message can indicate a reference time (for example, Treference).

[0039] The above-mentioned reference time can include at least one of the following:

[0040] Coordinated Universal Time (UTC);

[0041] Daylight Saving Time (DST), also referred to as or Summer Time;

[0042] Global Positioning System (GPS) time;

[0043] Local time.

[0044] When the UE receives the reference time, in order to ensure that the UE side time and the network side time are consistent, the protocol stipulates that the time position corresponding to the reference time received by the UE is the boundary of the system frame number (SFN) where the end boundary of the system message sending window of the system message is located.

[0045] For example, the position of the SIB16 where the UE receives the reference time is (SFN_2, Subframe_1), the system message sending window of the SIB16 is 10 subframes (i.e. Subframe) (wherein there are 10 subframes in 1 SFN), then the end boundary of the system message window corresponding to the SIB16 where the UE receives the reference time is (SFN_3, Subframe_1), and the reference time received by the UE corresponds to the end boundary time of SFN_3.

[0046] The reference time provided by the network side to the UE comes from a specific clock source. For example, for the GPS time provided by the network side to the UE, the clock source of the GPS time can be a GPS satellite; for the UTC time provided by the network side to the UE, the clock source of the UTC time can be an atomic clock connected to the network side device (such as a base station or a core network device, etc.) that can provide UTC time. Different clock sources can provide the same or different types of reference time, for example, clock source 1 and clock source 2 can both provide UTC time. When different clock sources provide the same or different types of reference time, the accuracy of the time information provided by the clock sources can be the same or different. For example, the granularity (or time accuracy) of the UTC time provided by clock source 1 is 1 second, and the granularity (or time accuracy) of the UTC time provided by clock source 2 is 1 microsecond.

[0047] II. Uplink timing

[0048] After receiving the downlink signal, the UE can determine the position of the downlink signal subframe. In order to avoid uplink interference, the network side needs to ensure that the signals sent by different UEs arrive at a fixed time, so the network side needs to configure a TA value for the uplink transmission of the UE. After receiving the TA value, if the UE needs to send an uplink signal, the UE can send the uplink signal by advancing the TA value with the downlink subframe position as the reference.

[0049] For TA value acquisition: since the UE only needs to acquire the TA value when it is in uplink out-of-sync state, the UE can be triggered by the network side or the UE itself to initiate a random access process, and the network side sends the TA value to the UE in the random access response.

[0050] For TA value maintenance: Since the UE's location is constantly changing, the validity of the TA value needs to be maintained. Network-side TA value maintenance can be achieved by setting a Time Alignment Timer (TAT) for the UE's TA value. This timer starts when the TA is sent to the UE, and a new TA value is sent to the UE before the TAT expires. UE TA value maintenance can be initiated or restarted upon receiving the TA value, based on the TAT set by the network side. After the TAT expires, the TA value is considered invalid, and the UE enters a state of uplink out of synchronization, no longer able to send uplink signals in the out-of-synchronization cell.

[0051] This disclosure provides an information transmission method. Referring to Figure 1, which is a structural diagram of a network system to which this disclosure can be applied, the system includes a terminal device 11 and a network-side device 12. The terminal device 11 can be a user-side device such as a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), or wearable device. It should be noted that this disclosure does not limit the specific type of the terminal device 11. The network-side device 12 can be a base station, such as a macro base station, an LTE evolved node base station (eNB), or a 5G New Radio base station (5G). th Network-side equipment 12 can be a small cell, such as a low-power node (LPN), pico, or femto, or an access point (AP). The base station can also be a network node composed of a central unit (CU) and multiple TRPs it manages and controls. It should be noted that the specific type of network-side equipment 12 is not limited in this embodiment.

[0052] In this embodiment, the network-side device 12 can deliver the reference time information to the terminal device 11 through system information (e.g., SIB10) and / or a dedicated message (e.g., RRCConnectionReconfiguration message), etc. The reference time information can include, but is not limited to, at least one of the type of reference time, the time accuracy of reference time, and the clock source of reference time, etc. It should be noted that the network-side device 12 can deliver one or more reference time information to the terminal device, and the reference time information can be used to indicate the reference time.

[0053] The terminal device 11 can report the reference time interest information to the network device 12. The reference time interest information, i.e., the interest information of the terminal device for the reference time, can be used to indicate at least one of the reference time interested by the terminal device 11 and the reference time not interested by the terminal device 11, etc.

[0054] Optionally, the reference time interest information can include, but is not limited to, at least one of the reference time information interested and the reference time information not interested, etc. The reference time information interested can represent the reference time information that has been received, is being received, or will be received by the terminal device 11, and the reference time information not interested can represent the reference time information that is no longer received by the terminal device 11.

[0055] After the network-side device 12 receives the reference time interest information, it can know whether the terminal device 11 is interested in the related reference time (e.g., the reference time delivered by the network side) based on the reference time interest information, so as to timely trigger the correction process of the related reference time to improve the accuracy of the reference time.

[0056] The embodiment of the present disclosure provides an information transmission method applied to a terminal device. Referring to FIG. 2, FIG. 2 is a flowchart of the information transmission method provided by the embodiment of the present disclosure, as shown in FIG. 2, the method includes the following steps:

[0057] Step 201, reporting reference time interest information to a network-side device;

[0058] The reference time interest information is used to indicate at least one of the reference time interested by the terminal device and the reference time not interested by the terminal device.

[0059] In this embodiment, the reference time interest information, i.e., the interest information of the terminal device for the reference time, can be used to indicate at least one of the reference time interested by the terminal device and the reference time not interested by the terminal device, etc.

[0060] The reference time of interest to the terminal device can represent a reference time that the terminal device has received, is receiving, or will receive, and the reference time of no interest to the terminal device can represent a reference time that the terminal device no longer receives.

[0061] The reference time can include, but is not limited to, one or more of UTC, DST, GPS time, and local time. It should be noted that the reference time information can be used to indicate the reference time.

[0062] In actual application, the network side device can deliver the reference time information to the terminal device through system information (for example, SIB10) and / or a dedicated message (for example, RRCConnectionReconfiguration message). The terminal device can report the reference time interest information to the network side device, so that the network side device can learn whether the terminal device is interested in the relevant reference time (for example, the reference time delivered by the network side) based on the reference time interest information, thereby being able to timely trigger the random access process and timely correct the relevant reference time.

[0063] In the embodiments of the present disclosure, the reference time interest information is reported to the network side device, wherein the reference time interest information is used to indicate at least one of the reference time of interest to the terminal device and the reference time of no interest to the terminal device, so that the network side can learn the interest information of the terminal device to the reference time in time, thereby being able to timely trigger the correction process of the relevant reference time and improve the accuracy of the reference time.

[0064] Optionally, the reference time interest information can include at least one of the following:

[0065] The reference time of interest information;

[0066] The reference time of no interest information.

[0067] In the embodiments, the reference time of interest information can represent the reference time information that the terminal device has received, is receiving, or will receive. The reference time of no interest information can represent the reference time information that the terminal device no longer receives.

[0068] For example, if the reference time information of interest includes a time precision a, it indicates that the terminal device has received or is receiving or will receive a reference time with a time precision of time precision a; if the reference time information of interest includes a clock source of industrial internet b1, it indicates that the terminal device has received or is receiving or will receive a reference time with a clock source of industrial internet b1; if the reference time information of no interest includes a clock source b2, it indicates that the terminal device no longer receives a reference time with a clock source of industrial internet b2; if the reference time information of no interest includes a reference time type DST, it indicates that the terminal device no longer receives a reference time with a reference time type of DST.

[0069] By reporting the reference time information of interest and / or the reference time information of no interest to the network side device, the terminal device can quickly learn the reference time of interest and / or the reference time of no interest from the network side device.

[0070] Optionally, the reference time information can include at least one of the following:

[0071] a type of reference time;

[0072] a time precision of reference time;

[0073] a clock source of reference time.

[0074] In this embodiment, the type of reference time can include UTC, DST, GPS or local time, etc. The time precision of reference time, which can also be referred to as the granularity of reference time, can include 1us, 1ms or 1s, etc. The clock source of reference time can include a GPS satellite, an atomic clock connected to the network side device and capable of providing UTC time or an industrial internet, etc.

[0075] It should be noted that the reference time information of interest can include at least one of the type of reference time, the time precision of reference time and the clock source of reference time, and the value of each parameter can be determined by the terminal device according to the actual situation. The reference time information of no interest can also include at least one of the type of reference time, the time precision of reference time and the clock source of reference time, and the value of each parameter can also be determined by the terminal device according to the actual situation.

[0076] For example, the interested reference time information can include type a1, time precision a1 and clock source a1, the uninterested reference time information can include type a2, time precision a2 and clock source a2; or the interested reference time information can include type b1, the uninterested reference time information can include time precision b1; or the interested reference time information can include type c1 and time precision c1, the uninterested reference time information can include type c2.

[0077] Optionally, the reporting of the reference time interest information to the network side device comprises:

[0078] If the protocol predefinition allows the terminal device to report the reference time interest information, the reference time interest information is reported to the network side device.

[0079] Or,

[0080] If the first indication information received from the network side device indicates that the terminal device is allowed to report the reference time interest information, the reference time interest information is reported to the network side device; wherein the first indication information is used to indicate whether the reporting of the reference time interest information is allowed.

[0081] In an embodiment, whether the terminal device is allowed to report the reference time interest information can be pre-defined by a protocol, in the case that the protocol predefinition allows the terminal device to report the reference time interest information, the reference time interest information is reported to the network side device, and in the case that the protocol predefinition does not allow the terminal device to report the reference time interest information, the reference time interest information is not reported to the network side device.

[0082] In this embodiment, whether the terminal device is allowed to report the reference time interest information can be pre-defined by a protocol, so that the signaling can be saved and the implementation is relatively simple.

[0083] In another embodiment, whether the terminal device is allowed to report the reference time interest information can be indicated by the network side device. For example, the network side device can indicate whether the terminal device is allowed to report the reference time interest information through system information (for example, SIBx) or dedicated signaling (for example, RRCReconfiguration message). When the network side device indicates that the terminal device is allowed to report the reference time interest information, the terminal device can report the reference time interest information.

[0084] For example, the network-side device can indicate the network-side capability information through system information (e.g., SIBx) or dedicated signaling (e.g., RRCReconfiguration message) to indicate whether the network-side device supports receiving the reference time interest information reported by the terminal device. In this case, the terminal device can report the reference time interest information only when the network-side device indicates that it supports receiving the reference time interest information reported by the terminal device.

[0085] The embodiment can improve the flexibility of the reporting control of the reference time interest information by indicating whether the terminal device is allowed to report the reference time interest information through the network-side device.

[0086] Optionally, the trigger condition for the terminal device to report the reference time interest information to the network-side device can include one of the following:

[0087] The terminal device is interested in at least one reference time information;

[0088] The terminal device is not interested in at least one reference time information;

[0089] The interest of the terminal device in at least one reference time information changes;

[0090] The first content reported by the terminal device changes, wherein the first content includes the content of the reference time information that the terminal device is interested in or the content of the reference time information that the terminal device is not interested in;

[0091] The terminal device detects that the received reference time information needs to be corrected.

[0092] In the embodiment, the at least one reference time information can be any reference time information.

[0093] In an embodiment, the terminal device can report the reference time interest information to the network-side device when the terminal device is interested in one or more reference time information. For example, the terminal device can report the reference time interest information to the network-side device when the terminal device has received, is receiving, or will receive the reference time information.

[0094] In another embodiment, the terminal device can report the reference time interest information to the network-side device when the terminal device is not interested in one or more reference time information. For example, the terminal device can report the reference time interest information to the network-side device when the terminal device determines to stop receiving the reference time information.

[0095] In another embodiment, the terminal device can report the reference time interest information to the network side device in case that the interest of the terminal device in the at least one reference time information changes. For example, the interest in a certain reference time information changes from interest to non-interest, or from non-interest to interest.

[0096] In another embodiment, the terminal device can report the reference time interest information to the network side device in case that the content of the interested reference time information or the content of the non-interested reference information reported by the terminal device changes. For example, the type of the interested reference time reported by the terminal device last time is UTC, and now changes to DTS; or the time accuracy of the interested reference time reported by the terminal device last time is 1s, and now changes to 1us; or the clock source of the interested reference time reported by the UE last time is Industrial Internet 1, and now changes to Industrial Internet 2, etc.

[0097] In another embodiment, the terminal device can report the reference time interest information to the network side device in case that the terminal device detects that the reference time information received by the terminal device needs to be corrected. For example, the UE detects that the uplink timing advance (i.e. TA) of the UE exceeds a threshold, and then reports the reference time interest information to the network side device.

[0098] The embodiment can trigger the terminal device to report the reference time interest information in case that the trigger condition is met, so as to reduce unnecessary reporting of the reference time interest information and save resources.

[0099] Optionally, the determination condition that the terminal device detects that the reference time information received by the terminal device needs to be corrected includes one of the following:

[0100] The path loss measured by the terminal device is greater than or equal to a first threshold value;

[0101] The path loss measured by the terminal device changes by an amount greater than or equal to a second threshold value;

[0102] The uplink timing advance of the terminal device is greater than or equal to a third threshold value;

[0103] The uplink timing advance measured by the terminal device changes by an amount greater than or equal to a fourth threshold value;

[0104] The indication information received by the terminal device from the network side device indicates that the cell needs to correct the reference time information.

[0105] In the embodiment, at least one of the first threshold value, the second threshold value, the third threshold value and the fourth threshold value can be configured by the network side or predefined by a protocol.

[0106] In an embodiment, the terminal device can determine that the reference time information received by the terminal device needs to be corrected when the path loss measured by the terminal device is greater than or equal to a first threshold value, or when the change in the path loss measured by the terminal device is greater than or equal to a second threshold value, or when the uplink timing advance of the terminal device is greater than or equal to a third threshold value, or when the change in the uplink timing advance measured by the terminal device is greater than or equal to a fourth threshold value, or when the indication information received by the terminal device from the network side device indicates that the reference time information needs to be corrected.

[0107] In another embodiment, the terminal device can determine that the reference time information received by the terminal device needs to be corrected when the uplink timing advance of the terminal device is greater than or equal to a third threshold value. For example, when the uplink timing advance is TA and the third threshold value is Threshold, the terminal device can determine that the reference time information received by the terminal device needs to be corrected when TA >= Threshold. When the uplink timing advance is TA / 2, the terminal device can determine that the reference time information received by the terminal device needs to be corrected when TA / 2 >= Threshold.

[0108] In another embodiment, the terminal device can determine that the reference time information received by the terminal device needs to be corrected when the change in the uplink timing advance measured by the terminal device is greater than or equal to a fourth threshold value. For example, when the previous uplink timing advance is TA1 and the current uplink timing advance is TA2 and the fourth threshold value is T4, the terminal device can determine that the reference time information received by the terminal device needs to be corrected when (TA2-TA1) >= T4.

[0109] In another embodiment, the terminal device can determine that the reference time information received by the terminal device needs to be corrected when the indication information received by the terminal device from the network side device indicates that the reference time information needs to be corrected. For example, the network side device can indicate that the reference time information with a precision of 1us needs to be corrected for the UEs in a macro cell (i.e., a cell with a larger radius).

[0110] It should be noted that the terminal device can directly report the reference time interest information to the network side device when the path loss measured by the terminal device is greater than or equal to a first threshold value, or when the change in the path loss measured by the terminal device is greater than or equal to a second threshold value, or when the uplink timing advance of the terminal device is greater than or equal to a third threshold value, or when the change in the uplink timing advance measured by the terminal device is greater than or equal to a fourth threshold value, or when the indication information received by the terminal device from the network side device indicates that the reference time information needs to be corrected.

[0111] Optionally, after the terminal device reports the reference time interest information to the network side device, the method can further include:

[0112] start a prohibit timer;

[0113] wherein the terminal device is prohibited from reporting the reference time interest information before the prohibit timer expires.

[0114] In this embodiment, after the terminal device reports the reference time interest information, the prohibit timer can be started, and during the running of the prohibit timer, the reporting of the reference time interest information is no longer triggered.

[0115] This embodiment can reduce the repeated reporting of the reference time interest information and save resources by prohibiting the reporting of the reference time interest information before the prohibit timer expires.

[0116] Optionally, the parameter of the prohibit timer is predefined by a protocol or configured by a network side.

[0117] In this embodiment, the parameter of the prohibit timer can include the duration of the prohibit timer.

[0118] An information transmission method is provided in the embodiments of the present disclosure, and is applied to a network side device. Referring to FIG. 3, FIG. 3 is a flowchart of the information transmission method provided by the embodiments of the present disclosure, and as shown in FIG. 3, the method includes the following steps:

[0119] Step 301, receiving reference time interest information reported by a terminal device.

[0120] The reference time interest information is used to indicate at least one of reference time that the terminal device is interested in and reference time that the terminal device is not interested in.

[0121] In this embodiment, the reference time interest information of the terminal device can be used to indicate at least one of reference time that the terminal device is interested in and reference time that the terminal device is not interested in.

[0122] The reference time that the terminal device is interested in can represent reference time that the terminal device has received, is receiving or will receive, and the reference time that the terminal device is not interested in can represent reference time that the terminal device no longer receives.

[0123] The reference time can include but is not limited to one or more of UTC, DST, GPS time and local time. It should be noted that the reference time information can be used to indicate reference time.

[0124] In actual application, the network side device can deliver the reference time information to the terminal device through system information (for example, SIB10) and / or dedicated message (for example, RRCConnectionReconfiguration message), and receive the reference time interest information from the terminal device, so that the network side device can know whether the terminal device is interested in the relevant reference time (for example, the reference time delivered by the network side) based on the reference time interest information, thereby being able to timely trigger the random access process and timely correct the relevant reference time.

[0125] In the embodiments of the present disclosure, the reference time interest information reported by the terminal device is received, wherein the reference time interest information is used to indicate at least one of the reference time interested by the terminal device and the reference time not interested by the terminal device. Thus, the network side can timely know the interest information of the terminal device on the reference time, thereby being able to timely trigger the correction process of the relevant reference time and improve the accuracy of the reference time.

[0126] Optionally, the reference time interest information can include at least one of the following:

[0127] the reference time information interested;

[0128] the reference time information not interested.

[0129] In the embodiments, the reference time information interested can represent the reference time information that has been received or is being received or will be received by the terminal device. The reference time information not interested can represent the reference time information that is no longer received by the terminal device.

[0130] For example, if the reference time information interested includes time accuracy a, it represents that the terminal device has received or is receiving or will receive the reference time with time accuracy a; if the reference time information interested includes clock source industrial internet b1, it represents that the terminal device has received or is receiving or will receive the reference time with clock source industrial internet b1; if the reference time information not interested includes clock source b2, it represents that the terminal device no longer receives the reference time with clock source industrial internet b2; if the reference time information not interested includes reference time type DST, it represents that the terminal device no longer receives the reference time with reference time type DST.

[0131] The embodiments of the present disclosure facilitate the network side device to quickly know the reference time interested by the terminal device and / or the reference time not interested by the terminal device by reporting the reference time information interested and / or the reference time information not interested to the network side device.

[0132] Optionally, the reference time information can include at least one of the following:

[0133] a type of the reference time;

[0134] a time precision of the reference time;

[0135] a clock source of the reference time.

[0136] In the embodiment, the type of the reference time can include UTC, DST, GPS or local time, etc. The time precision of the reference time, which can also be referred to as the granularity of the reference time, can include 1us, 1ms or 1s, etc. The clock source of the reference time can include a GPS satellite, an atomic clock connected to a network side device and capable of providing UTC time or an industrial internet, etc.

[0137] It should be noted that the reference time information of interest can include at least one of the type of the reference time, the time precision of the reference time and the clock source of the reference time, and the value of each parameter can be determined by the terminal device according to actual conditions. The reference time information of no interest can also include at least one of the type of the reference time, the time precision of the reference time and the clock source of the reference time, and the value of each parameter can also be determined by the terminal device according to actual conditions.

[0138] For example, the reference time information of interest can include type a1, time precision a1 and clock source a1, and the reference time information of no interest can include type a2, time precision a2 and clock source a2; or the reference time information of interest can include type b1, and the reference time information of no interest can include time precision b1; or the reference time information of interest can include type c1 and time precision c1, and the reference time information of no interest can include type c2.

[0139] Optionally, the method can further include:

[0140] sending first indication information to the terminal device, wherein the first indication information is used to indicate whether the terminal device is allowed to report reference time information of interest.

[0141] In the embodiment, whether the terminal device is allowed to report the reference time information of interest is indicated by the network side device.

[0142] For example, whether the terminal device is allowed to report the reference time information of interest can be indicated by the network side device through system information (for example, SIBx) or dedicated signaling (for example, RRCReconfiguration message).

[0143] For example, the network-side device can indicate the network-side capability information through system information (e.g., SIBx) or dedicated signaling (e.g., RRCReconfiguration message) to indicate whether the network-side device supports receiving the reference time interest information reported by the terminal device. In this case, the terminal device can report the reference time interest information only when the network-side device indicates that it supports receiving the reference time interest information reported by the terminal device.

[0144] The embodiment can improve the flexibility of the reporting control of the reference time interest information by indicating whether the terminal device is allowed to report the reference time interest information through the network-side device.

[0145] Optionally, the method further includes:

[0146] configuring the terminal device with a parameter of the prohibit timer.

[0147] In the embodiment, the parameter of the prohibit timer can include a time length of the prohibit timer.

[0148] Optionally, the network-side device is a source node.

[0149] After receiving the reference time interest information reported by the terminal device, the method further includes:

[0150] sending the reference time interest information to a target node.

[0151] In the embodiment, for a mobility procedure, the source node can receive the reference time interest information sent by the terminal device and send the reference time interest information to the target node.

[0152] For example, the gNB1 sends the reference time interest information received from the terminal device to the target gNB2 in a handover procedure, or the master node (MN) or the secondary node (SN) sends the reference time interest information received from the terminal device to the target SN in an SN addition or change procedure.

[0153] The embodiments of the present disclosure are described below in combination with examples:

[0154] The information transmission method provided by the embodiments of the present disclosure includes the following steps:

[0155] In step a1, the network side sends reference time information to the UE through system information (e.g., SIB10) and / or dedicated messages (e.g., RRCConnectionReconfiguration message).

[0156] Optionally, the network side configures or agrees through a protocol whether the UE is allowed to report its reference time interest information.

[0157] For example, the network side indicates whether the UE is allowed to report its reference time interest information via system information (e.g., SIBx) or dedicated signaling (e.g., RRCReconfiguration message).

[0158] For example, the network side indicates the network side capability information via system information (e.g., SIBx) or dedicated signaling (e.g., RRCReconfiguration message) to indicate whether the network side supports receiving the reference time interest information reported by the UE. In this case, the UE is only allowed to report the reference time interest information if the network side indicates that it supports receiving the reference time interest information reported by the UE.

[0159] Optionally, the network side can also configure or agree on a prohibit timer (i.e., prohibitTimer) configuration (e.g., the duration of the prohibit timer) during which the UE is not allowed to report the reference time interest information.

[0160] Step a2, the UE reports the reference time interest information to the network side.

[0161] The reference time interest information can include one or more of the following in any combination:

[0162] Reference time information of interest;

[0163] Reference time information of no interest.

[0164] The reference time information of interest can represent reference time information that the UE has received or is receiving or will receive.

[0165] The reference time information of no interest can represent reference time information that the UE no longer receives.

[0166] The reference time information can include one or more of the following in any combination:

[0167] Type of reference time; for example, UTC, or DST, or GPS, or local time, etc.

[0168] Time accuracy (or granularity) of reference time; for example, 1us, or 1ms, or 1s, etc.

[0169] Clock source of reference time; for example, clock information provided by Industrial Internet 1, or clock information provided by Industrial Internet 2.

[0170] The trigger condition for the UE to trigger the reporting of the reference time interest information can include any of the following:

[0171] The UE is interested in specific reference time information;

[0172] The UE is not interested in the specific reference time information;

[0173] The UE's interest in the specific reference time information changes; for example, from interested to not interested, or from not interested to interested;

[0174] The content of the reference time information that the UE reports as interested or not interested changes; for example, the type of reference time that the UE previously reported as interested is UTC, and now changes to DTS; or the accuracy of the reference time that the UE previously reported as interested is 1s, and now changes to 1us; or the clock source of the reference time that the UE previously reported as interested is Industrial Internet 1, and now changes to Industrial Internet 2, etc.

[0175] The UE detects that the reference time information it receives needs to be corrected; for example, the UE detects that its TA exceeds a threshold.

[0176] Optionally, the decision condition for the UE to detect that the reference time information it receives needs to be corrected (i.e., whether the reference time information needs to be corrected) includes any of the following:

[0177] The path loss measured by the UE is greater than or equal to a first threshold; wherein the first threshold can be configured by the network side or agreed by the protocol;

[0178] The amount of change in the path loss measured by the UE is greater than or equal to a second threshold; wherein the second threshold can be configured by the network side or agreed by the protocol; for example, if the path loss at the last time of reference time calibration is P1, the current path loss is P2, and the second threshold is T2, when (P2-P1)>=T2, it is determined that the reference time information received by the UE needs to be corrected;

[0179] The uplink timing advance of the UE is greater than or equal to a third threshold; wherein the threshold can be configured by the network or agreed by the protocol; for example, if the uplink timing advance is TA, and the third threshold is Threshold, when TA>=Threshold, it is determined that the reference time information received by the UE needs to be corrected; if the uplink timing advance is TA / 2, when TA / 2>=Threshold, it is determined that the reference time information received by the UE needs to be corrected;

[0180] The UE measures an uplink timing advance change amount greater than or equal to a fourth threshold value; wherein the threshold value can be configured by the network or agreed by a protocol; for example, a previous uplink timing advance is TA1 (or TA1 / 2), a current uplink timing advance is TA2 (or TA2 / 2), and the fourth threshold value is T4. When (TA2-TA1) >= T4, it is determined that the reference time information received by the UE needs to be corrected.

[0181] The UE receives indication information from the network side indicating that the reference time information needs to be corrected in a specific cell; for example, the network side indicates that all UEs in the macro cell (i.e., a cell with a larger radius) need to correct the reference time information with a precision of 1us.

[0182] Optionally, if the network side configures or agrees by a protocol to prohibit the configuration of the prohibition timer, the UE starts the prohibition timer after reporting the reference time interest information, and does not trigger the reporting of the reference time interest information during the running of the prohibition timer.

[0183] Optionally, the source node receiving the reference time interest information reported by the UE can send the reference time interest information to the target node in a mobility process.

[0184] For example, the gNB1 sends the reference time interest information to the target gNB2 in a handover process; or the MN or the SN sends the reference time interest information received from the terminal device to the target SN in an SN addition or change process.

[0185] By reporting the interest information of the reference time by the UE, the network side can know whether the UE is interested in the reception of the reference time and what precision of the reference time is needed, so that the network side can trigger the correction process of the related reference time in time, and the UE can obtain more accurate reference time.
