Description

Technical Field

[0001] The invention belongs to the technical field of network communications, and in particular relates to a merging enhancement method in communications. Background Art

[0002] In network communications, the sent data may be lost, damaged, or out of order due to various reasons such as network congestion, noise interference, transmission errors, etc. In order to ensure the reliable transmission of data, a retransmission mechanism is introduced.

[0003] The retransmission mechanism is a technology used to detect and resolve data transmission errors during the communication process. It is implemented through negotiation and judgment between the sender and the receiver. By detecting and correcting errors in transmission, the retransmission mechanism can significantly improve the reliability and stability of data. It can also adjust the sending rate of the sender to adapt to the congestion level of the network, thereby optimizing the data transmission efficiency.

[0004] However, there are some problems and challenges with the retransmission mechanism. First, retransmission will cause a certain delay, because the sender can only resend the data packet after the receiver sends a confirmation message or selects a retransmission request, which takes a certain amount of time. Second, the retransmission mechanism requires a certain amount of network bandwidth, which will increase the network transmission burden and may cause more network congestion. Finally, because retransmission needs to wait for confirmation information or select a retransmission request, the real-time performance of data transmission will be reduced.

[0005] Therefore, the retransmission mechanism in current communications has the problems of long delay time, low real-time performance and low transmission efficiency. Summary of the invention

[0006] The purpose of the present invention is to provide a merging enhancement method in communication to solve the problems of long delay time, low real-time performance and low transmission efficiency in the retransmission mechanism in current communication.

[0007] To achieve the above object, the present invention adopts the following technical solution:

[0008] In one aspect, the present specification provides a method for enhancing merging in communication, including:

[0009] Step 102, determining the number of merging times;

[0010] Step 104, based on the time slot number and the number of merging times, the data is sent from the transmitting end to the receiving end, and stored in the receiving end buffer;

[0011] Step 106, performing separate analysis of each time slot on the data in the receiving buffer to obtain equalized data and corresponding SNR values ​​for each time slot;

[0012] Step 108: Merge the equalized data based on the SNR value to obtain merged data.

[0013] On the other hand, the present specification provides a merging enhancement device in communication, including:

[0014] A merge times agreement module is used to determine the merge times;

[0015] A data transmission module, used to send data from the transmitting end to the receiving end based on the time slot number and the number of merging times, and store the data in the receiving end buffer;

[0016] A data analysis module is used to analyze the data in the receiving buffer separately for each time slot to obtain the equalized data and the corresponding SNR value of each time slot;

[0017] The data merging module is used to merge the equalized data based on the SNR value to obtain merged data.

[0018] Based on the above technical solution, this specification can achieve the following technical effects:

[0019] This method can reduce time delay and improve real-time performance by agreeing on the number of merging times between the sending end and the receiving end, canceling the link in the retransmission mechanism where the receiving end sends confirmation information or selects a retransmission request, and canceling the feedback link; by enhancing the merging algorithm, lossy data is removed, the merging gain is increased, and the transmission rate and merging effectiveness are improved.

[0020] This method uses the sender to repeatedly send the same data packet, and does not require the receiving node to feedback information before sending. The sender and the receiver agree to have the same number of merging times, thereby reducing the delay and real-time loss caused by the retransmission mechanism.

[0021] This method selects different merging times according to the merging algorithm when the receiving end performs merging and parsing. The receiving end does not actually need to perform the agreed number of merging, because the merged multi-channel data may contain noise interference or data with antenna loss, which will bring negative gain to the merging, so these data need to be removed to improve the merging performance.

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are all in very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0033] It should be noted that, in order to clearly explain the content of the present invention, the present invention specifically cites multiple embodiments to further illustrate different implementations of the present invention, wherein the multiple embodiments are enumerated rather than exhaustive. In addition, for the sake of brevity of explanation, the contents mentioned in the previous embodiments are often omitted in the subsequent embodiments. Therefore, the contents not mentioned in the subsequent embodiments can refer to the previous embodiments accordingly.

[0034] Example 1

[0035] Please refer to Figure 1 , Figure 1 It is shown that this embodiment provides a merging enhancement method in communication.

[0036] Signal errors may occur after various factors interfere with the signal. Digital communication systems need strong anti-interference capabilities to effectively improve the quality of digital transmission signals. The enhanced repetitive transmission strategy means that the transmitter repeatedly sends the same data packet multiple times, and the receiving node does not need to feedback information between transmissions. The receiving end uses merging technology to improve the receiving gain, thereby improving the reliability of transmission.

[0037] Wireless transmission reliability can be defined as:

[0038]

[0039] Where Φ(X) is the cumulative distribution function of the standard normal distribution:

[0040]

[0041] in:

[0042] p tran : Transmit power

[0043] G: Transmitting antenna gain

[0044] n0: average background noise

[0045] Y th : The signal-to-noise ratio required to successfully receive data.

[0046] The repeated transmission strategy is adopted to improve the reliability of the wireless link. Each data to be sent is repeated K times. The reliability of the wireless link between sending and receiving is:

[0047]

[0048] The general target signal-to-noise ratio and the number of repeated transmissions have the following corresponding relationship:

[0049] Residual_BLER=Target_BLER N

[0050] Where: N is the number of repeated transmissions, for example, 10 -3 As the target BLER, two retransmissions are performed, which can usually reach 10 -5 According to the minimum bit rate of 0.0586, under the typical time slot configuration, 12*273*12*800 / 2=921kbps can be transmitted.

[0051] The RLC layer can only perform simple retransmissions and cannot merge retransmission data, so there is no merging gain and the RLC layer retransmission delay is extended. The physical layer can merge retransmissions and because the physical layer is implemented on the base station side, the retransmission delay can also be reduced.

[0052] The merging technology combines the received repeatedly transmitted data packets for decoding to improve the transmission efficiency. By using the merging technology, each transmission is fully utilized, not only the time diversity gain is obtained, but also the requirement for the first transmission BLER is reduced due to repeated transmission, which also reduces the requirement for the first transmission power, so some power gain will be obtained, thereby improving system performance and power utilization efficiency.

[0053] In this embodiment, the method includes:

[0054] Step 102, determining the number of merging times;

[0055] Step 104, based on the time slot number and the number of merging times, the data is sent from the transmitting end to the receiving end, and stored in the receiving end buffer;

[0056] In this embodiment, one implementation of step 104 is:

[0057] Step 202, the transmitting end sends the data of the previous time slot or new data according to the current time slot number and the number of merging times;

[0058] In this embodiment, one implementation of step 202 is:

[0059] Step 2021: The transmitting end divides the number of combinations by an integer according to the current time slot number and obtains a remainder to obtain a first remainder.

[0060] Step 2022, determine whether the first remainder is 0, if so, send new data in the current time slot and clear the sender buffer, and store the new data in the sender buffer; if not, repeat sending the data of the previous time slot in the current time slot.

[0061] Step 204: The receiving end receives the data of the previous time slot or new data according to the current time slot number and the number of merging times and stores them in the receiving end buffer.

[0062] In this embodiment, one implementation of step 204 is:

[0063] Step 2041: The receiving end divides the number of combinations by an integer according to the current time slot number to obtain a remainder to obtain a second remainder;

[0064] Step 2042, determine whether the second remainder is 0. If so, determine that the received data is new data and clear the receiving buffer to store the new data in the receiving end buffer; if not, determine that the received data is data from the previous time slot and continue to store the received data in the receiving end buffer.

[0065] Step 106, performing separate analysis of each time slot on the data in the receiving buffer to obtain equalized data and corresponding SNR values ​​for each time slot;

[0066] In this embodiment, one implementation of step 106 is:

[0067] Step 302, screening the equalized data based on the SNR value of each time slot to obtain the equalized data that meets the merging requirements;

[0068] In this embodiment, one implementation of step 302 is:

[0069] Step 3021, sort the SNR values ​​of each time slot from large to small to obtain an SNR sequence;

[0070] Step 3022, taking the median value in the SNR sequence to obtain the SNR median;

[0071] Step 3023, based on the SNR sequence and the SNR median, obtaining a target SNR value lower than the SNR median;

[0072] Step 3024: Screen the equalized data based on the difference between the target SNR value and the SNR median value to obtain the equalized data that meets the merging requirements.

[0073] In this embodiment, one implementation of step 3024 is:

[0074] Calculate the difference between the target SNR value and the SNR median value and determine whether the difference is lower than a preset threshold. If so, determine that the balanced data corresponding to the SNR value is balanced data that does not meet the merging requirements. If not, determine that the data corresponding to the SNR value is balanced data that meets the merging requirements.

[0075] Step 304, performing cumulative calculation on the balanced data that meets the merging requirement to obtain cumulative data;

[0076] Step 306, averaging the accumulated data to obtain combined data.

[0077] Step 108: Merge the equalized data based on the SNR value to obtain merged data.

[0078] In this embodiment, after step 108, the following steps are further included:

[0079] Step 110, performing bit-level analysis on the combined data to obtain final analyzed data.

[0080] Specifically, this embodiment provides a method for enhancing the merging of communications, and the specific method steps are as follows:

[0081] Step 1: The sending end and the receiving end set the initial number of merging times, for example, the number of merging times is N=4;

[0082] Step 2: The sender divides the number of merging times according to the sending time slot number and takes the remainder. When the remainder is 0, it sends new data, clears the sender buffer, and then stores the data.

[0083] Step 3: The transmitter divides the number of merging times according to the transmission time slot number and takes the remainder. When the remainder is not 0, the data in the buffer is sent, that is, the data of the previous time slot is sent repeatedly;

[0084] Step 4: The transmitter repeats steps 2 and 3 for each time slot to determine whether to send new data;

[0085] Step 5: The receiving end divides the number of merging times according to the receiving time slot number and takes the remainder. When the remainder is 0, it is considered that new data has been sent, the receiving end buffer is cleared, and then the data is stored;

[0086] Step 6: The receiving end divides the number of merging times according to the receiving time slot number and takes the remainder. If the remainder is not 0, it is considered that the sending end is sending repeatedly, and the data continues to be put into the buffer;

[0087] Step 7: The receiving end performs steps 5 and 6 each time, and the buffer stores all the received data within the merge times before the receiving end parses it;

[0088] Step 8: Analyze the data in the buffer for each time slot separately, and the equalized output data after analysis overwrites the time slot data in the buffer; the MIMO equalization method is not required, and the equalized data and the corresponding SNR are output. MMSE equalization is used in the present invention, and the SNR calculation formula is:

[0089]

[0090] in:

[0091] is the transmitting antenna / layer number;

[0092] for No. diagonal element values.

[0093] Step 9: Merge the equalized output data. The merging method here is to directly accumulate and average the equalized data. At this time, data selection should be performed based on the SNR calculated after equalization. The median of all SNRs should be taken. Data that is more than 2dB lower than the median SNR is considered to be contaminated and should be discarded when merging. Figure 2 The figure is a flowchart of the receiving end when merging and parsing repeatedly sent data.

[0094] Step 10: Perform bit-level analysis on the merged data to obtain the final analyzed data.

[0095] According to the above steps, the method can obtain a certain gain in an ideal channel or a fading channel, in a scenario with or without interference.

[0096] The specific gain is as follows:

[0097] Depend on Figure 2-Figure 4 It can be seen that under AWGN, the channel is ideal and the combining gain is limited, but in the presence of interference, the combining gain is obvious.

[0098] Depend on Figure 5-Figure 7 It can be seen that in a fading channel, the repeated combining gain is 2-3dB, and in the presence of interference, the combining gain is 4-6dB.

[0099] Based on this, it is shown that this method can bring about a more obvious performance improvement in resisting fading and interference through repeated merging.

[0100] In summary, this method can reduce time delay and improve real-time performance by agreeing on the number of merging times at the sending and receiving ends, canceling the link in the retransmission mechanism where the receiving end sends confirmation information or selects a retransmission request, and canceling the feedback link; by enhancing the merging algorithm, lossy data is removed, the merging gain is improved, and the transmission rate and merging effectiveness are improved.

[0101] This method uses the sender to repeatedly send the same data packet, and does not require the receiving node to feedback information before sending. The sender and the receiver agree to have the same number of merging times, thereby reducing the delay and real-time loss caused by the retransmission mechanism.

[0102] This method selects different merging times according to the merging algorithm when the receiving end performs merging and parsing. The receiving end does not actually need to perform the agreed number of merging, because the merged multi-channel data may contain noise interference or data with antenna loss, which will bring negative gain to the merging, so these data need to be removed to improve the merging performance.

If so, the balanced data corresponding to the SNR value is determined to be balanced data that does not meet the merging requirements; if not, the data corresponding to the SNR value is determined to be balanced data that meets the merging requirements.

[0135] When the device performs merging and parsing at the receiving end, it selects different merging times according to the merging algorithm. The receiving end does not actually need to perform the agreed number of merging, because the merged multi-channel data may contain noise interference or antenna loss data, which will bring negative gain to the merging, so these data need to be removed to improve the merging performance.
