Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.
The detailed description of the present application is further described in detail below with reference to the drawings and examples. The following examples are illustrative of the present application, but are not intended to limit the scope of the present application.
Example 1
Fig. 1 is a flowchart of a method for acquiring a relative GPS offset of a radio frame header according to an embodiment of the present application, as shown in fig. 1, where the method includes:
s1, acquiring GPS second pulse;
s2, acquiring a first synchronous pulse of the 4G synchronous device and a second synchronous pulse of the 5G synchronous device;
s3, starting counting operation on the GPS second pulse to obtain GPS second pulse point data;
s4, obtaining an offset value of the 4G wireless frame head relative to the GPS according to the GPS second pulse point data and the first synchronous pulse;
s5, obtaining the offset value of the 5G wireless frame head relative to the GPS according to the GPS second pulse point number data and the second synchronous pulse.
In the implementation process, the offset value of the 4G wireless frame head relative to the GPS and the offset value of the 5G wireless frame head relative to the GPS are obtained through the GPS second pulse, the first synchronous pulse and the second synchronous pulse, so that the error of the obtained offset value is reduced, the difficulty in obtaining the offset of the wireless frame head is reduced, the efficiency in obtaining the offset value is improved, and the cost is reduced.
In a TDD system, the same frequency domain resource is used to transmit and receive data, and uplink and downlink are distinguished by time. Some base stations cannot exist at the same time as uplink time slots, and some base stations cannot exist at the same time as downlink time slots. The base stations of the same system can acquire time synchronization by using GPS second pulse. However, in different systems, due to different frame structures, even if GPS time synchronization is acquired, relative synchronization on uplink and downlink timeslots cannot be guaranteed. The public network configuration of the 4G synchronous device and the public network configuration of the 5G synchronous device are overlapped on frequency domain resources, and when rising edges of the first synchronous pulse and the second synchronous pulse are aligned with rising edges of GPS second pulse, some uplink and downlink time slots are in conflict, so that the offset of a wireless frame head relative to the GPS needs to be obtained.
The TDD radio frame structure in the 4G synchronization device is that one radio frame is 10ms, and one radio frame is divided into 2 half frames, each half frame is 5ms, each half frame contains 5 subframes, and each subframe is 1ms. The TDD wireless frame structure supports various uplink and downlink configurations.
Multiple subcarrier spacings are supported in the 5G synchronization apparatus (subcarrier spacings are fixed at 15KHz in 4G). Taking this embodiment as an example, the configuration of the public network TDD is that the subcarrier spacing is 30Khz, and there are 20 slots in a radio frame corresponding to this configuration. TDD in 5G synchronization devices supports more flexible uplink and downlink slot configurations.
In S1, a GPS pulse per second is acquired.
The GPS generates a pulse signal of a synchronization pulse every second after synchronization, and a GPS pulse per second is generated at the start 0 time of every second. Counting the number of GPS second pulses of two adjacent times can quantize the 1 second time period into point data, and the later obtained first synchronization pulse point data and second synchronization pulse point data are also offset from the beginning 0 time of each second. Thus, the acquisition of the GPS second pulse can be performed with the first and second synchronization pulses to calculate the offset value.
Further, S4 includes:
interrupting the rising edge of the first synchronization pulse;
starting counting operation on the first synchronous pulse interrupting the rising edge to obtain first synchronous pulse point number data;
and obtaining the offset value of the 4G wireless frame head relative to the GPS according to the GPS second pulse point data and the first synchronous pulse point data.
In the implementation process, the rising edge of the first synchronization pulse is interrupted, so that the counting operation can be more accurate, the obtained first synchronization pulse point data is more accurate, errors are reduced, and the difficulty of obtaining the offset value of the 4G wireless frame head relative to the GPS is reduced.
The GPS generates a second pulse to the central processing unit (Central Processing Unit, CPU), the CPU interrupts the rising edge of the GPS second pulse, starts counting operation, records the point data of the GPS second pulse when the rising edge of the next GPS second pulse arrives, and restarts counting operation, and repeats the process, and averages for a plurality of times, so as to obtain the point data Count1 corresponding to 1 s.
After the 4G synchronization device synchronizes with the 4G network, a first synchronization pulse is generated at the beginning of each radio frame, the CPU interrupts the rising edge of the first synchronization pulse, and records the number of the first synchronization pulse point data Count2 at the moment, and the Offset value offset_4G of the 4G radio frame head relative to the GPS is as follows: offset_4g=count2×1000000/Count1.
Further, S5 includes:
interrupting the rising edge of the second sync pulse;
counting the second synchronous pulse of the interrupted rising edge to obtain second synchronous pulse point number data;
and obtaining the offset value of the 5G wireless frame head relative to the GPS according to the GPS second pulse point data and the second synchronous pulse point data.
In the implementation process, the rising edge of the second synchronization pulse is interrupted, so that the counting operation can be more accurate, the obtained second synchronization pulse point data is more accurate, errors are reduced, and the difficulty of obtaining the offset value of the 5G wireless frame head relative to the GPS is reduced.
The 5G synchronization device generates a second synchronization pulse at the beginning of each radio frame slot0 and gives it to the CPU after synchronization with the 5G network. The CPU interrupts the rising edge of the second synchronization pulse, and records the Offset value offset_5G of the second synchronization pulse point number data Count3,5G wireless frame head relative to the GPS at the moment as follows: offset_5g=count3.1000000/Count 1.
Further, before the step of counting the GPS pulse per second to obtain the GPS pulse per second point data, the method further includes:
the rising edge of the GPS pulse-per-second is interrupted.
In the implementation process, the CPU starts the counting operation after interrupting the rising edge of the GPS second pulse, interrupts the rising edge of the GPS second pulse, can facilitate the subsequent counting operation, and provides references for the first synchronous pulse and the second synchronous pulse.
