Abstract
Description
Technical Field
[0001] The present invention relates to the field of communication technology, and in particular to a data processing method for resisting electrostatic interference. Background Art
[0002] Wireless communication technology is a technology that transmits information through the air through electromagnetic waves. This information can be voice, data or video. Wireless communication technologies include but are not limited to Wi-Fi, Bluetooth, cellular networks, satellite communications, etc. These technologies usually use specific frequency ranges for communication, for example, Wi-Fi usually uses 2.4GHz and 5GHz bands.
[0003] The electrostatic effect is the electric force generated by the accumulated charge of an object. When two objects come into contact and separate, they may generate static electricity due to friction. This static electricity generates electric and magnetic fields. When the electrostatic field interacts with electromagnetic waves, it may change the propagation path or strength of the electromagnetic waves, such as directing the signal away from its intended path, or increasing or decreasing the strength of the signal. This may cause communication interruption, data loss, or degradation of communication quality. Especially in cases where the communication distance is long, the impact of the electrostatic effect may be more obvious.

[0052] For ease of understanding, the embodiment of the present application takes the access device as an access device for wireless short-range communication, such as an AP in a Wi-Fi system as an example. In this case, the terminal may be a STA.
[0053] Figure 2 The flowchart of the method provided by the embodiment of the present invention is as follows. The anti-static interference data processing method is applicable to the anti-static interference data processing system mentioned above, and involves the interaction between the access device and the terminal. The specific process is as follows:
[0054] S201: An access device obtains first data and second data to be transmitted by a terminal.
[0055] The terminal is connected to the access device through a wireless short-range access method, such as establishing a Wi-Fi connection between the terminal and the access device.
[0056] The first data and the second data may both be service data of the terminal, such as downlink data of the service, and specifically may be data of services such as pictures, videos, and texts. The access device may obtain the first data and the second data to be transmitted by the terminal from the data network (DN).
[0057] S202: When the access device transmits first data to the terminal using a first beam of the access device, the access device determines that electrostatic interference exists in the transmission of the first data.
[0058] The first beam is the main beam configured by the access device for the terminal, that is, the beam that points to the terminal and has the best signal strength, which can be selected through beam measurement. The access device uses the first beam of the access device to transmit the first data to the terminal, that is, the access device maps the first data to resources (such as resource elements (RE)), and then maps the resources to the antenna port corresponding to the first beam, so as to realize the transmission of the first data.
[0059] When the access device transmits first data to the terminal using the first beam of the access device, the access device receives confirmation information fed back by the terminal for the first data. The confirmation information is used to indicate data in the first data that the terminal fails to receive. For example, the data of the first data can be carried with RE as the granularity, and the confirmation information can indicate which REs the terminal fails to receive data on, such as indicating the indexes of these REs.
[0060] The access device can determine, based on the confirmation information, that static electricity interference exists in the transmission of the first data.
[0061] For example, the first data is carried on M resource element groups in the time-frequency position set, where M is an integer greater than 2, and each of the M resource element groups includes multiple resource elements in the time-frequency position set. For example, each of the M resource element groups includes multiple resource elements in the time-frequency position set, which means that each of the M resource element groups includes 4 REs whose time-frequency positions are adjacent in sequence, such as 4 REs whose positions are distributed as 2*2 or 1*4. The time-frequency position concentration of the M resource element groups means that the time-frequency positions of the M resource element groups are adjacent in sequence. In other words, the access device can reduce transmission delay and improve transmission efficiency by transmitting the first data through the M resource element groups in the time-frequency position set. For example, M=4, the M resource element groups include resource element group #1, resource element group #2, resource element group #3, and resource element group #4, and the specific time-frequency distribution can be as follows Figure 3 As shown, in Figure 3 In the example, each resource element group includes a pilot, such as a demodulation reference signal (DMRS), which is used by the terminal to demodulate the first data.
[0062] It can be understood that the purpose of dividing the resource element groups is to retransmit the data of the resource element group as a whole in the event of data packet loss in the resource element group, so that the terminal can jointly demodulate the data on the resource element group received by the initial transmission and retransmission based on DMRS, which is an energy enhancement method. Therefore, the division granularity of the resource element groups, that is, the number of REs needs to be moderate. If the number is too small, it will affect the demodulation performance of the retransmission. If the data is too much, the transmission efficiency will be reduced. Therefore, the number of 4, 6 or 8 is more appropriate.
[0063] On this basis, the access device determines the K resource element groups where the data that the terminal failed to receive among the M resource element groups are located according to the confirmation information, where K is an integer greater than 1 and less than or equal to M. When the value of K is greater than the threshold, the access device determines that there is electrostatic interference in the transmission of the first data. For example, K=4, the threshold is 3, and another example is K=6, the threshold is 5, and another example is K=8, the threshold is 6 / 7. In other words, under normal circumstances, packet loss may occur randomly, such as packet loss data in a certain resource element group, but if there is electrostatic interference, it may cause packet loss in the entire bandwidth at the full delay, that is, packet loss occurs in most of the M resource element groups, that is, K is greater than or the threshold, so the access device can determine that there is electrostatic interference in the transmission of the first data.
[0064] S203: In response to electrostatic interference existing in the transmission of the first data, the access device transmits second data to the terminal using the first beam and the second beam of the access device.
[0065] The second beam is an auxiliary beam configured by the access device for the terminal. The beam indexes of the first beam and the second beam are continuous, that is, they are also beams pointing to the terminal, but the signal strength of the beam is less than the signal strength of the first beam. It is the beam with the second largest signal strength among the beams received by the terminal.
[0066] The access device can use the first beam of the access device to transmit the second data to the terminal, and the access device also uses the second beam to transmit the second data to the terminal. Specifically, the access device carries the second data on the RE corresponding to the pilot in the second pilot pattern in the first pilot pattern according to the first pilot pattern of the first beam and the second pilot pattern of the second beam, and then transmits the second data to the terminal through the first beam. And, the access device can carry the second data on the RE corresponding to the pilot in the first pilot pattern in the second pilot pattern according to the first pilot pattern and the second pilot pattern, and then transmit the second data to the terminal through the second beam.
[0067] One possible way:
[0068] The time-frequency positions of the pilots in the first pilot pattern and the pilots in the second pilot pattern are different. Each pilot in the first pilot pattern is adjacent to the time-frequency position of a corresponding pilot in the second pilot pattern. Two pilots in the first pilot pattern and the second pilot pattern that are adjacent in time-frequency position are a pilot pair. There are multiple pilot pairs in total, and the number of multiple pilot pairs is the number of pilots in the first pilot pattern or the first pilot pattern. For the target pilot pair carrying the second data in the multiple pilot pairs, the target pilot pair includes the first pilot in the first pilot pattern and the second pilot in the second pilot pattern. In the first pilot pattern, a portion of the second data is carried on the RE at the time-frequency position of the second pilot, and in the second pilot pattern, a portion of the data is carried on the RE at the time-frequency position of the first pilot. In other words, each data in the second data is carried on the RE where the DMRS is located, so that the terminal can use the first pilot to demodulate the data on the RE at the time-frequency position of the second pilot. If the demodulation fails, the first pilot and the second pilot are used to jointly demodulate the data. For example, the terminal can calculate the noise of the first channel based on the first pilot, and calculate the noise of the second channel based on the second pilot. Since the first beam and the second beam are continuous, and the time-frequency positions of the first pilot and the second pilot are also adjacent, the difference between the first channel and the second channel is not large, so the noise of the first channel and the noise of the second channel can be weighted and summed, such as the weight of the first channel can be greater than the weight of the second channel, and it is conducive to the demodulation of the data by the noise after weighted summation. At the same time, the terminal can also use the second pilot to demodulate the data on the RE at the time-frequency position of the first pilot (that is, the same data as the above data). If the demodulation fails, the second pilot and the first pilot are used to jointly demodulate the data, which can greatly improve the success rate of demodulation, so it can resist electrostatic interference under long-distance weak signal transmission and improve transmission reliability.
[0069] For ease of understanding, the following Figure 4 Introduction, such as Figure 4 As shown, DMRS1 and DMRS5 are a pilot pair, DMRS2 and DMRS6 are a pilot pair, DMRS3 and DMRS7 are a pilot pair, and DMRS4 and DMRS8 are a pilot pair. The two pilots in each pilot pair, that is, the time-frequency positions of DMRS are adjacent. Data #1 is carried at the position of DMRS5 in the first pilot pattern, which is convenient for subsequent joint demodulation using DMRS5. Similarly, data #2 is also carried at the position of DMRS1 in the second pilot pattern, which is convenient for subsequent joint demodulation using DMRS1. The same is true for data #2-4, which will not be repeated.
[0070] In another possible manner, the first pilot pattern and the second pilot pattern both include N resource element groups, N is an integer greater than 1, in the first pilot pattern, each of the N resource element groups has a resource element that carries a pilot in the first pilot pattern, and in the second pilot pattern, each of the N resource element groups has a resource element that carries a pilot in the second pilot pattern, and the pilots in the first pilot pattern and the pilots in the second pilot pattern have different time-frequency positions. The second data is divided into K portions of data, and the K portions of data are carried one-to-one on K resource element groups in the N resource element groups, K is an integer greater than 1 and less than or equal to N, for any target data in the K portions of data, the target data is carried on a target resource element group carried in the K resource element groups, in the first pilot pattern, the target data is carried on other resource elements in the target resource element group except the pilots in the first pilot pattern, and in the second pilot pattern, the target data is carried on other resource elements in the target resource element group except the pilots in the second pilot pattern. It can be seen that similar to the transmission method of the first data, each piece of data can be retransmitted with the resource element group as the granularity, and the same piece of data is additionally sent through the second beam. Compared with the transmission of the first data, it can improve reliability to combat electrostatic interference under long-distance weak signal transmission.
[0071] In summary, when the terminal accesses the access device via wireless short-range access, if the access device determines that there is electrostatic interference in the transmission of the first data when using the first beam of the access device to transmit the first data of the terminal to the terminal, then for subsequent data transmission of the terminal data, the access device can use the first beam and the second beam of the access device to simultaneously transmit the second data to the terminal, that is, to combat the packet loss caused by electrostatic interference by enhancing the transmission, thereby ensuring the reliability of the transmission.
