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 using electromagnetic waves. This information can be voice, data, or video. Wireless communication technologies include but are not limited to Wi-Fi, Bluetooth, cellular networks, and satellite communications. These technologies typically communicate using specific frequency ranges. For example, Wi-Fi typically uses the 2.4 GHz and 5 GHz bands.

[0003] The electrostatic effect is the electric force generated by the accumulated charge on an object. When two objects come into contact and then separate, they may generate static electricity due to friction. This static electricity generates electric and magnetic fields. When the static field interacts with electromagnetic waves, it may alter the propagation path or intensity of the electromagnetic waves, for example, directing the signal away from its intended path or increasing or decreasing the signal's strength. This can lead to communication interruptions, data loss, or decreased communication quality. The impact of the electrostatic effect can be particularly noticeable over long communication distances.

[0004] Therefore, how to achieve data transmission that is resistant to electrostatic interference is a current research issue. Summary of the Invention

[0052] For the convenience of understanding, the embodiments of the present application take the access device as a wireless short-range communication access device, such as an AP in a Wi-Fi system. In this case, the terminal can be a STA.

[0053] Figure 2 A flowchart of a method provided by the embodiments of the present application is shown. The anti-static interference data processing method is applicable to the anti-static interference data processing system described above, and involves the interaction between the access device and the terminal. The specific process is as follows:

[0054] In S201, the access device obtains first data and second data to be transmitted by the terminal.

[0055] The terminal accesses the access device in a wireless short-range access manner, such as establishing a Wi-Fi connection with the access device.

[0056] The first data and the second data can be service data of the terminal, such as downlink data of a service, and can be data of a service such as a picture, a video, and text. The access device can obtain the first data and the second data to be transmitted by the terminal from a data network (DN).

[0057] In a case where the access device transmits the first data to the terminal using the first beam of the access device, the access device determines that the transmission of the first data exists electrostatic interference.

[0058] The first beam is a main beam configured by the access device for the terminal, that is, a beam pointing to the terminal and having the best signal strength, and can be selected by beam measurement. The access device transmits the first data to the terminal using the first beam of the access device, that is, the access device maps the first data to a resource (such as a resource element (RE)), and then maps the resource to an antenna port corresponding to the first beam, that is, to achieve transmission of the first data.

[0059] In a case where the access device transmits the first data to the terminal using the first beam of the access device, the access device receives acknowledgment information fed back by the terminal for the first data. The acknowledgment information is used to indicate data in the first data that fails to be received by the terminal, for example, the first data can be carried in REs as a granularity, and the acknowledgment information can indicate REs on which the terminal fails to receive data, such as indexes of the REs.

[0060] The access device can determine, according to the acknowledgment information, that the transmission of the first data exists electrostatic interference.

[0061] For example, the first data is carried on M resource element groups in a time-frequency location set, M is an integer greater than 2, and each of the M resource element groups includes a plurality of resource elements in the time-frequency location set. For example, each of the M resource element groups includes 4 REs in the time-frequency location set in sequence, such as 2*2 or 1*4. The time-frequency locations of the M resource element groups are in sequence. That is, the access device transmits the first data through the M resource element groups in the time-frequency location set, which can reduce the transmission delay and improve the transmission efficiency. 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 shown in FIG. 1B, where each resource element group contains a pilot such as a demodulation reference signal (DMRS) for the terminal to demodulate the first data. Figure 3 Figure 3

[0062] ​​It can be understood that the resource element groups are divided in order to perform retransmission of the data in the resource element group as a whole in the case of data packet loss in the resource element group, so that the terminal can perform joint demodulation of the data on the resource element group received by initial transmission and retransmission based on the DMRS, that is, energy enhancement, and 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, the demodulation performance of the retransmission will be affected, and if the data is too much, the transmission efficiency will be reduced, and therefore the number of 4 or 6 or 8 is more appropriate.

[0063] On this basis, the access device determines, according to the confirmation information, K resource element groups in which the terminal fails to receive the data in the M resource element groups, K being an integer greater than 1 and less than or equal to M. In the case where the value of K is greater than a threshold value, the access device determines that the transmission of the first data is subject to electrostatic interference. For example, K = 4 and the threshold value is 3, for another example, K = 6 and the threshold value is 5, and for another example, K = 8 and the threshold value is 6 / 7. That is, under normal circumstances, packet loss may occur randomly, such as data loss in a certain resource element group, but if there is electrostatic interference, it may cause packet loss on the entire bandwidth in the full time delay, that is, most of the M resource element groups have packet loss, that is, K is greater than or equal to the threshold value, and therefore the access device can determine that the transmission of the first data is subject to electrostatic interference.

[0064] S203, in response to the transmission of the first data being subject to electrostatic interference, the access device transmits second data to the terminal using a first beam and a second beam of the access device.

[0065] The second beam is a secondary beam configured by the access device for the terminal, the beam indexes of the first beam and the second beam are continuous, that is, also refer to the beams pointing to the terminal, but the signal strength of the beam is less than that of the first beam, such as the second largest beam in the signal strength of the beams received by the terminal.

[0066] The access device can transmit the second data to the terminal using the first beam of the access device, and at the same time, the access device also transmits the second data to the terminal using the second beam. Specifically, the access device carries the second data on the RE corresponding to the pilot in the first pilot pattern and the second 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. In addition, the access device can carry the second data on the RE corresponding to the pilot in the first pilot pattern and 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] In 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 with adjacent time-frequency positions in the first pilot pattern and the second pilot pattern constitute a pilot pair. There are multiple pilot pairs in total, and the number of pilot pairs is equal to the number of pilots in the first pilot pattern or the first pilot pattern. For a target pilot pair carrying second data among 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, one 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, one portion of the data is carried on the RE at the time-frequency position of the first pilot. In other words, each portion of the second data is carried on the RE where the DMRS is located. In this way, the terminal can use the first pilot to demodulate the data on the RE at the time-frequency position of the second pilot. If 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. For example, the weight of the first channel can be greater than the weight of the second channel, and it is beneficial to demodulate the data with 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. This can greatly improve the success rate of demodulation, thereby being able to combat 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 the DMRSs are adjacent. Data #1 is carried at the position of DMRS5 in the first pilot pattern, which facilitates the subsequent joint demodulation using DMRS5. Similarly, data #2 is also carried at the position of DMRS1 in the second pilot pattern, which facilitates the subsequent joint demodulation using DMRS1. The same applies to data #2-4, which will not be repeated here.

[0070] In another possible mode, the first pilot pattern and the second pilot pattern each include N resource element groups, N being an integer greater than 1, in the first pilot pattern, one resource element in each of the N resource element groups carries a pilot in the first pilot pattern, in the second pilot pattern, one resource element in each of the N resource element groups also carries a pilot in the second pilot pattern, and the pilots in the first pilot pattern and the pilots in the second pilot pattern are different in time-frequency location. The second data is divided into K pieces of data, the K pieces of data are carried on K resource element groups in the N resource element groups in one-to-one correspondence, K being an integer greater than 1 and less than or equal to N, and for any target data in the K pieces of data, the target data is carried on other resource elements in a target resource element group in the K resource element groups, except for the pilot in the first pilot pattern, in the first pilot pattern, and the target data is carried on other resource elements in the target resource element group, except for the pilot in the second pilot pattern, in the second pilot pattern. It can be seen that, similar to the transmission mode of the first data, each piece of data can be retransmitted in the granularity of a resource element group, and the same piece of data is additionally transmitted through the second beam, compared with the transmission of the first data, the reliability can be improved to resist electrostatic interference under long-distance weak signal transmission.

[0071] In summary, in the case that the terminal accesses the access device in a wireless short-range access mode, if the access device determines that the transmission of the first data of the terminal exists electrostatic interference in the case that the access device transmits the first data of the terminal to the terminal using the first beam of the access device, the access device can transmit the second data to the terminal using the first beam and the second beam of the access device for subsequent data transmission of the terminal, that is, the enhanced transmission is used to resist packet loss caused by electrostatic interference, so as to ensure the reliability of transmission.
