It should be noted that, in the embodiment of the present invention, the specific type of the network-side device is not limited.
Referring to fig. 2, fig. 2 is a flowchart of a method for transmitting synchronization time information according to an embodiment of the present invention, as shown in fig. 2, including the following steps:
201. a terminal determines a synchronization time difference value between a first cell and a second cell, wherein the synchronization time difference value is determined according to system information in the first cell and the second cell or time reference information (reference time) contained in dedicated signaling;
202. and the terminal reports the synchronization time difference to network side equipment of at least one cell of the first cell and the second cell.
The synchronization time difference may be a difference between the time reference information of the first cell and the time reference information of the second cell.
The synchronization time difference between the first cell and the second cell may be a high-precision synchronization time difference between the first cell and the second cell, where the high-precision synchronization time difference refers to a synchronization time difference with a time information precision higher than that of the subframe-level time information. For example: the granularity of the synchronization time difference is less than or equal to 250 nanoseconds, such as 250 nanoseconds or 10 nanoseconds.
In addition, in the embodiment of the present invention, the time reference information may be high-precision time reference information, and specifically, the time reference information may be time reference information with a granularity higher than that of a subframe level, for example: time reference information having a granularity of less than or equal to 250 nanoseconds, such as time reference information having a granularity of 250 nanoseconds or 10 nanoseconds.
Further, the System information or dedicated signaling may be System information or dedicated signaling used for transmitting high-precision time parameter information, such as System Information Block (SIB) 9 or SIB 16.
In the embodiment of the present invention, the first cell and the second cell may be two cells in a non-dual connection scenario, and the two cells may be two cells belonging to different network side devices. For example: one cell belongs to the cell of the synchronization source network side device, and the other cell belongs to the cell of the other network side device, such as the target network side device. In addition, the terminal can move under the network side equipment, and the terminal reports the synchronization time difference to the network side equipment, so that the terminal can maintain high-precision synchronization among different equipment in a scene of crossing the network side equipment.
In addition, the reporting, by the terminal, of the synchronization time difference to the network-side device of at least one of the first cell and the second cell may be that the terminal reports the synchronization time difference to the network-side device of the first cell, or reports the synchronization time difference to the network-side device of the second cell, and reports the synchronization time difference to the network-side devices of the first cell and the second cell.
In the embodiment of the present invention, the network side device may obtain more available time information, and further, the network side device may perform communication operations such as synchronization and transmission delay compensation based on the synchronization time difference, so as to improve the communication performance of the network side device.
As an optional implementation manner, the first cell includes a serving cell, and the second cell includes a neighbor cell.
In this embodiment, the terminal may read system information or dedicated signaling of the current serving cell and the neighboring cell, where the system information or dedicated signaling is information/signaling containing high-precision time reference information, so as to determine the synchronization time difference.
Optionally, the reporting, by the terminal, the synchronization time difference value to the network side device of at least one cell of the first cell and the second cell includes:
and the terminal reports the synchronization time difference to network side equipment of a service cell.
In this embodiment, reporting the synchronization time difference to the serving cell can be achieved.
For example: as shown in fig. 3, the method comprises the following steps:
step 1, a terminal reads system information (such as LTE SIB16) related to high-precision synchronization sent by a serving cell/network side device, or receives dedicated signaling (such as LTE dlinformation transfer) related to high-precision synchronization sent by the serving cell/network side device, so as to obtain high-precision time of the serving cell/network side device (for example, LTE Release15 may reach 250 nsec granularity);
step 2, the terminal reads system information of the neighbor cell/network side device to obtain high-precision time of the neighbor cell/network side device to obtain the neighbor cell/base station (for example, LTE Release15 can reach 250 nsec granularity, NR can reach 10 nsec granularity); further, reading system information of the neighboring cell/network side device, or reading scheduling information in the SIB1 of the neighboring cell/network side device, determining a transmission timing of the high-precision time-dependent SIB of the neighboring cell/network side device, and actually reading the high-precision time-dependent SIB according to the scheduled transmission timing;
and 3, the terminal determines the high-precision synchronization time difference values from different cells/network side equipment, such as the high-precision time difference values of the different cells/network side equipment. And if the high-precision time precision of different cells/network side equipment is different, taking larger time granularity for alignment. For example: the terminal acquires the time reference information with the granularity of 250ns of the serving cell and the time reference information with the granularity of 10ns of the adjacent cell, and then the synchronization time difference value of the time precision can be calculated according to the larger granularity of 250 ns;
step 4, the terminal reports the time precision synchronization time difference to the serving cell/network side device, and in addition, the terminal can indicate the granularity information used by the synchronization time difference while reporting, and further, the terminal can also carry the identification information of the adjacent cell/network side device;
and step 5, after receiving the high-precision synchronization time difference, the serving cell/network side device may be used for its own network side time calculation compensation, for example, determining propagation delay compensation between the serving cell and the neighboring cell, or sending the high-precision synchronization time difference to the neighboring cell/network side device participating in the calculation, for the network side time calculation compensation of the neighboring cell/network side device, or for device synchronization processing across network side devices.
Further, before the terminal determines the synchronization time difference between the first cell and the second cell, the method further includes:
the terminal receives configuration information sent by network side equipment of the serving cell, wherein the configuration information includes at least one of the following:
indication information for indicating the second cell;
a granularity indication of the synchronization time difference.
The granularity indication may be a granularity indication of high-precision synchronization time difference calculation, for example: if the granularity required by the network side equipment is 1 microsecond, the difference value of the granularity lower than 1 microsecond does not need to be calculated and reported according to the actual receiving granularity of 250 nanoseconds/10 nanoseconds, so that the overhead is reduced.
For example: and calculating the high-precision synchronous time difference of the terminal based on the configuration of the network side. The serving cell of the terminal may send high-precision synchronization calculation configuration information to the terminal, which may include one or more of the following:
calculating and reporting a high-precision difference value between the adjacent network side equipment and the network side equipment;
granularity indication of high precision difference calculation.
As an optional implementation manner, before the terminal determines the synchronization time difference between the first cell and the second cell, the method further includes:
the terminal acquires the time reference information of the first cell through the system information or the special signaling of the first cell, and acquires the time reference information of the second cell through the system information or the special signaling of the second cell;
the terminal determines a synchronization time difference value between a first cell and a second cell, and comprises the following steps:
and the terminal determines the synchronous time difference between the first cell and the second cell according to the time reference information of the first cell and the time reference information of the second cell.
Wherein, the determining, by the terminal, a synchronization time difference between the first cell and the second cell according to the time reference information of the first cell and the time reference information of the second cell includes:
and the terminal calculates a difference value between a first synchronization time value and a second synchronization time value to obtain the synchronization time difference value, wherein the first synchronization time value is a synchronization time value corresponding to the time reference information of the first cell, and the second synchronization time value is a synchronization time value corresponding to the time reference information of the second cell.
The first synchronization time value may be time reference information of the first cell itself, and the second synchronization time value may be time reference information of the second cell itself. Alternatively, the first synchronization time value may be a synchronization time value determined by the terminal based on the time reference information of the first cell, and the second synchronization time value may be a synchronization time value determined by the terminal based on the time reference information of the second cell.
The terminal may calculate a difference between the first synchronization time value and the second synchronization time value to obtain the synchronization time difference, and subtract the first synchronization time value and the second synchronization time value calculated by the terminal to obtain the synchronization time difference.
Optionally, if the granularity of the time reference information of the first cell is different from the granularity of the time reference information of the second cell, the granularity of the synchronization time difference value is:
a larger granularity of the time reference information of the first cell and the granularity of the time reference information of the second cell; or
Granularity of network side indication.
In this embodiment, the synchronization time value can be calculated with a large granularity, which makes the calculated synchronization time difference more accurate.
As an optional implementation manner, the reporting, by the terminal, the synchronization time difference to the network side device of at least one of the first cell and the second cell includes:
the terminal sends a report message to the network side equipment of at least one of the first cell and the second cell, wherein the report message includes the synchronization time difference value, and also includes at least one of the following:
granularity information and cell information of the synchronization time difference;
if the terminal sends the report message to the network-side device of the first cell, the cell information includes information of the second cell, or if the terminal sends the report message to the network-side device of the second cell, the cell information includes information of the first cell.
In this embodiment, since the granularity information of the synchronization time difference and the cell information are reported, the network side device can better utilize the synchronization time difference reported by the terminal.
In addition, after receiving the synchronization time difference, the network side device may calculate propagation delay compensation between the network side devices to improve transmission performance, and may also send the synchronization time difference to another network side device, for example, through interface signaling or inter-node messages, the other network side device sends the synchronization time difference. Further, the other network side device may determine propagation delay compensation between the network side devices according to the synchronization time difference; or, according to the synchronization time difference, performing synchronization processing between the network side devices to achieve synchronization between the network side devices.
For example: after receiving the high-precision synchronization time difference reported by the terminal, the serving cell of the terminal may transmit the information in an interface message, or transmit the information in a time-related inter-node message (e.g., inter-node message) to the neighboring network side device.
If passed in the interface message, a NODE CONFIGURATION UPDATE procedure (e.g., NG-RAN NODE CONFIGURATION UPDATE or ENB CONFIGURATION UPDATE signaling) may be used to send a high precision synchronization time difference between the two network side devices;
the measurementtiminconfiguration signaling may be used if passed in an internode message, internode message.
In the embodiment of the invention, a terminal determines a synchronization time difference value between a first cell and a second cell, wherein the synchronization time difference value is determined according to system information or time reference information contained in a dedicated signaling in the first cell and the second cell; and the terminal reports the synchronization time difference to network side equipment of at least one cell of the first cell and the second cell. Therefore, the network side equipment can acquire more available time information.
