Description

Data analysis method and related equipment Technical field

The present application relates to the field of communications, and in particular, to a method for data analysis and related equipment.

Background technique

In a communication system, for example, in a Long Term Evolution (LTE) system, downlink data is sent to a user equipment (UE) by a base station. After receiving the downlink data, the UE feeds back the demodulation result of the downlink result by the UE to the base station through uplink data, that is, a hybrid automatic repeat request (HARQ) feedback, and the base station performs the downlink HARQ feedback. The next step is processing, for example, retransmission of downlink data. In addition, in a communication system, for example, in the LTE system, the modulation method and code rate used to send downlink data are based on the channel quality indication (CQI) feedback from the UE, so the UE also needs to feedback via uplink data CQI. After receiving the uplink data sent by the UE, the base station needs to analyze the uplink data, and the analysis method may be cyclic redundancy code (CRC) analysis. If the base station parses the uplink data correctly, the corresponding parsing result is ACK (positive response); if the base station parses the uplink data incorrectly, the parsing result is NACK (negative response); if the uplink signal cannot be parsed, the base station It is considered that the UE has not transmitted, and the corresponding analysis result is discontinuous transmission (DTX).

The UE may send uplink data to the base station through a physical uplink shared channel (physical uplink shared channel, PUSCH). When the UE has downlink HARQ feedback and CQI information to be sent to the base station at the same time, then the downlink HARQ feedback and CQI information can be sent along with the uplink data to the base station at the same time. If the downlink HARQ feedback and CQI information pass the PUSCH along with the uplink data, the base station performs CRC analysis on the uplink data. If the analysis result of the uplink data is DTX, that is, the base station cannot detect the uplink data, and the base station processes the uplink data according to the DTX. At this time, the base station determines that the analysis result of the downlink HARQ feedback or the CQI information is a random value according to the analysis result of the uplink data. Therefore, the base station cannot determine whether the downlink HARQ feedback and CQI information obtained through analysis are reliable. Therefore, the base station cannot accurately perform processing according to the downlink HARQ feedback and the CQI information.

Summary of the invention

The embodiments of the present application provide a data analysis method and related equipment, which are used to analyze and determine downlink HARQ feedback and CQI information in uplink associated data associated with uplink data, and obtain reliable downlink HARQ feedback and CQI values.

In view of this, the first aspect of the present application provides a data analysis method, which may include:

The base station receives uplink data and uplink associated data sent by the UE. The uplink associated data includes downlink automatic retransmission request HARQ feedback and / or channel quality indication CQI information. The downlink HARQ feedback is the downlink data sent by the UE to the base station. In feedback, the CQI information includes a CQI of a channel between the UE and the base station. The base station parses the uplink data and the uplink accompanying data. If the base station determines that the analysis result of the uplink data is a discontinuous transmission DTX, the base station determines the feedback result of the downlink HARQ feedback and / or the CQI information based on the analysis result of the downlink HARQ feedback and / or CQI information. CQI value.

In the embodiment of the present application, after receiving the uplink data and uplink associated data sent by the UE, the base station analyzes the uplink data and uplink associated data. If the base station performs a joint analysis on the analysis result of the uplink data and the analysis result of the downlink HARQ feedback and / or CQI information, determine the feedback result of the downlink HARQ feedback and / or the CQI value in the CQI information. Therefore, in this application, the analysis result of the downlink data and the analysis result of the downlink HARQ feedback and / or CQI information are jointly analyzed to determine the feedback result of the downlink HARQ feedback and / or the CQI value in the CQI information. It can prevent the base station from misusing the random CQI value, causing data transmission errors between the base station and the UE, and invalid downlink HARQ feedback retransmission, thereby improving the utilization of air interface resources.

In some optional implementation manners, the base station determining the CQI value in the feedback information and / or CQI information of the downlink HARQ feedback according to the analysis result of the downlink HARQ feedback and / or CQI information may include:

If the base station determines that the uplink accompanying data includes only one of the downlink HARQ feedback and the CQI information, the base station determines that one of the uplink accompanying data is an invalid value.

In the embodiment of the present application, if the base station parses only one of the downlink HARQ feedback and the CQI information in the uplink accompanying data, then the base station may consider that the uplink accompanying data analysis is inaccurate. At this time, one of them can be discarded to prevent the base station from misusing the inaccurate value and improve the reliability of data transmission by the base station.

In some optional implementation manners, the base station determining the feedback result of the downlink HARQ feedback and / or the CQI value in the CQI information according to the analysis result of the downlink HARQ feedback and / or CQI information may include:

If the base station determines that the uplink accompanying data includes the uplink HARQ feedback and the CQI information, and the base station determines that the analysis result of the CQI information is DTX, the base station determines that the feedback result of the downlink HARQ feedback is DTX.

In the embodiment of the present application, if the analysis result of the uplink data is DTX, and the uplink HARQ feedback and the CQI information are determined according to the analysis result in the uplink accompanying data, when the analysis result of the CQI information is DTX, the downlink HARQ feedback is considered The feedback result is DTX to avoid invalid downlink HARQ feedback retransmission.

In some optional implementation manners, after the base station determines that the feedback result of the downlink HARQ feedback is DTX, the method may further include:

The base station determines that the UE obtains the downlink data according to a feedback result of the downlink HARQ feedback, and retransmits the downlink data.

In the embodiment of the present application, if the feedback result of the downlink HARQ feedback is DTX, the base station confirms that the UE has not received or parsed the downlink data. At this time, the base station may retransmit the downlink data, so that the UE can successfully obtain Downstream data.

In some optional embodiments, the method may further include:

If the base station determines that the uplink accompanying data includes the uplink HARQ feedback and the CQI information, and the base station determines that the analysis result of the CQI information is not DTX, the base station uses the demodulation result of the CQI information as the CQI value, The analysis value of the downlink HARQ feedback is used as the feedback result.

In the embodiment of the present application, if the analysis result of the uplink data is DTX, and the uplink accompanying data includes uplink HARQ feedback and CQI information. Then, if the analysis result of the CQI information is non-DTX, the base station can consider that the uplink associated data is correctly analyzed, and the base station uses the demodulation result of the CQI information as the CQI value, and uses the analysis value of the downlink HARQ feedback as the Feedback results. In order to obtain correct downlink HARQ feedback and CQI value, avoid invalid data retransmission, and obtain correct CQI value.

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. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall into the protection scope of the present application.

Embodiments of the present application provide a data analysis method and related equipment, which are used to analyze and determine downlink HARQ feedback and CQI information in uplink associated data that accompanies uplink data, and obtain reliable downlink HARQ feedback and CQI values.

The system architecture to which the solutions provided in the embodiments of the present application can be applied is shown in FIG. 1, which is mainly composed of a UE, a base station, and a core network. Multiple base stations may be connected by X2 or Xn interfaces and access the core network. The UE accesses the base station and establishes a connection with the core network through the base station. For example, if UE1 accesses base station 1, base station 1, base station 2, and base station 3 establish an X2 / Xn interface connection, and UE2 accesses base station 3, UE1 and UE2 may establish a connection with the core network through base station 1 and base station 3 and communicate with each other And data transmission. The data analysis method provided in this application is applied to data transmission between a UE and a base station. Specifically, the base station analyzes the uplink data transmitted by the UE and the uplink data associated with the uplink data. The uplink accompanying data includes downlink HARQ feedback and CQI information. The downlink HARQ feedback is the feedback of the UE to the received downlink data sent by the base station. The CQI information includes a CQI value, that is, a channel quality indication between the UE and the base station. The base station can determine the modulation mode and code rate used for sending downlink data in the system according to the CQI. The base station analyzes the uplink data and uplink associated data. If the analysis result of the uplink data by the base station is DTX, the base station can more accurately determine whether the downlink HARQ feedback and CQI information included in the uplink accompanying data are available according to the analysis result of the downlink HARQ feedback and the CQI information, and the discarding is invalid Downlink HARQ feedback and CQI information. The data analysis method and related equipment provided in this application will be described in detail below.

It should be noted that the solutions provided in the embodiments of the present application can be applied to the LTE system, and can also be applied to other communication systems that can accompany data, such as code division multiple access, frequency division multiple access, time division multiple access, and orthogonal frequency. Multiple access, single carrier frequency division multiple access and other access technology systems, and the fifth generation 5G new radio access network (new radio, NR) system. Correspondingly, the base station can be an evolved universal terrestrial radio access network (evolved universal terrestrial radio access network, EUTRAN) base station (evolved Node B, eNB), or it can be an LTE-NR The base station (gNodeB, gNB) in a non-standalone (NSA) non-standalone network (radio, new wireless access) is specifically adjusted according to the actual scenario, which is not limited here.

The process of the data analysis method provided in the embodiment of the present application is shown in FIG. 2 and may include:

201. Receive uplink data and uplink associated data sent by a UE.

First, the base station receives uplink data and uplink associated data sent by the UE. The uplink data is transmission data sent by the UE to the base station, and the uplink associated data is data associated with the uplink data. The uplink accompanying data may include downlink HARQ feedback and / or CQI information. The downlink HARQ feedback is the feedback of the UE to the downlink data sent by the base station. The uplink data and the uplink associated data are encoded and sent by the UE together, and are in the same data packet. For example, the UE sends uplink data A, data B, and data C to the base station along with the uplink data A. Then, the UE can send a piece of data to the base station, including uplink data A and uplink associated data. The uplink associated data includes data. B and data C.

Specifically, the downlink data is sent by the base station to the UE. After receiving the downlink data, the UE demodulates the downlink data. The UE then sends the demodulation result to the base station through downlink HARQ feedback. The downlink HARQ feedback may include: ACK, NACK, and DTX. ACK means that the UE parses the downlink data correctly. NACK means that the UE parsed the downlink data incorrectly and did not get the correct downlink data. The specific reasons include the loss or misalignment of the downlink data during transmission. DTX means that the UE does not parse the downlink data. When the base station resolves that the downlink HARQ feedback result is ACK, the base station determines that the UE has correctly parsed the downlink data, and the base station does not need to retransmit the downlink data or query the UE. If the base station resolves that the downlink HARQ feedback result is NACK, the base station determines that the UE has not correctly parsed the downlink data, and may perform retransmission or other processing on the downlink data. If the base station resolves that the downlink HARQ feedback result is DTX, the base station determines that the UE parses the downlink data incorrectly, or the UE does not receive the downlink data. At this time, the base station may retransmit the downlink data or perform other processing.

In some communication systems, such as the LTE system, the modulation method and code rate used by the base station to send downlink data are adjusted by continuing the CQI fed back by the UE. CQI reporting methods can be divided into multiple types. For example, the CQI can be reported periodically through a physical uplink control channel (PUCCH), and the base station allocates PUCCH resources. The periodically reported CQI is divided into different modes: Mode 1-0, Mode 1-1, Mode 2-0, Mode 2-1, and so on. It may also report the CQI non-periodically through the PUSCH. Each report requires the base station to notify the UE to report the CQI through uplink scheduling signaling, and then the UE reports the CQI to the base station through the PUSCH. Aperiodic CQI reporting can be divided into modes: Mode 1-2, Mode 2-0, Mode 2-2, Mode 3-0, Mode 3-1, and so on. In different transmission scenarios, the UE may report the CQI through different CQI reporting modes. CQI classification according to feedback granularity can be divided into full bandwidth CQI and subband CQI. A full-bandwidth CQI means that one CQI is fed back through the entire bandwidth. The subband CQI feedbacks the CQI through part of the bandwidth, for example, the cell bandwidth is 12 resource blocks (RB), and the subband CQI only takes up 6 RBs. Exemplarily, the subband CQI feedback is shown in Table 1:

Table 1

For example, the cell bandwidth is 8-10 RBs, Mode 2-0 for non-periodic CQI, Mode 2-2 occupies 2 RBs, and other modes, including periodic CQI and non-periodic CQI, can occupy 4 RBs, and so on.

The UE can send uplink data through the PUSCH. At the same time, when the UE has downlink HARQ feedback and CQI information to be sent to the base station at the same time, in order to save network resources and improve network transmission efficiency, the downlink HARQ feedback and CQI information can be uplink data along the way. It is sent to the base station through the PUSCH channel together with the uplink data, that is, the uplink is associated with the channel.

202. Parse uplink data and uplink associated data. If the analysis result of the uplink data is DTX, perform step 203. If the analysis result of the uplink data is non-DTX, perform step 209.

After receiving the uplink data and the uplink associated data, the base station parses the uplink data and the uplink associated data to obtain the analysis result of the uplink data and the uplink associated data. The analysis includes performing a CRC check on the uplink data and uplink associated data. If the analysis result of the uplink data is DTX, step 203 is performed. If the analysis result of the uplink data is non-DTX, step 209 is performed.

Specifically, when the UE sends uplink data and uplink associated data, it needs to perform CRC addition, encoding, and rate matching on the uplink data and uplink associated data before sending to the base station. After receiving the uplink data and uplink associated data, the base station needs to perform de-rate matching, decoding, and CRC check on the uplink data and uplink associated data.

Exemplarily, a specific CRC addition, encoding, and other steps of a UE, and a process of decoding verification by a corresponding base station are taken as examples.

First, the UE performs CRC addition and encoding processes as shown in FIG. 3. First, the UE determines a transmission block (transmit block) that needs to be transmitted. The TB includes the uplink data and uplink associated data. The uplink associated data may include downlink HARQ feedback and / or CQI information. The UE performs an additional CRC on the TB, that is, attaches a preset length check code. The check code can be calculated by the UE through the TB and the agreed generator polynomial, and the check code can be appended to the end of the TB. It is used for subsequent receiving equipment to check the TB, so that the receiving equipment can obtain accurate data. For example, in a 5G access network (New Radio, NR) system, when the length of a TB is greater than 3824 bits, a 24-bit generator polynomial is agreed. The check code can be calculated from the additional TB and the 24-bit generator polynomial. The length of the check code is also 24 bits. The check code is appended to the end of the TB. The TB after the check code can be divided by the agreed generator polynomial; when the length of the TB is not greater than 3824 bits, a 16 is agreed. Bit polynomial. The check code can be calculated from the TB without additional 24 bit generator polynomial. The length of the check code can be 16 bits. The check code is appended to the end of the TB. Can be divisible by the agreed generator polynomial. For example, the agreed 24-bit generator polynomial and the agreed 16-bit generator polynomial can be:

G _{CRC_24} (D) = D ²⁴ + D ²³ + D ¹⁸ + D ¹⁷ + D ¹⁴ + D ¹¹ + D ¹⁰ + D ⁷ + D ⁶ + D ⁵ + D ⁴ + D ³ + D + 1,

G _{CRC_16} (D) = D ¹⁶ + D ¹² + D ⁵ +1.

Afterwards, the UE may slice the TB into multiple code blocks (CBs), or may not slice the TB, and may adjust it according to the length of the TB or other factors. The specific method of segmenting the CB may be that one TB is evenly divided into multiple CBs, or the UE may be divided into a preset number of CBs according to a preset rule. After the UE divides the TB into multiple CBs, it appends a CRC check code to each CB for subsequent CRC check of the CB data. The way of adding the CRC check code is similar to the way of adding the CRC check code to the TB. The length of the CRC check code can be 4 bits, 16 bits, or 24 bits, which is not limited here. If the UE does not divide the TB into multiple CBs, CRC may not be added to the CBs. For example, in a 5G NR system, the length of the CRC appended to each CB is 24 bits, and the agreed generator polynomial can be: G (D) = D ²⁴ + D ²³ + D ⁶ + D ⁵ + D + 1. After the UE adds a CRC check code to each CB, the UE performs channel coding on the CB after the CRC check code is added. The channel coding may include Low Density Parity Check Code (LDPC) coding or forward Error correction (forward error correction, FEC) coding, etc. The LDPC encoding includes a preset check mode, or a preset LDPC check matrix check code, etc., and can be used by the receiving device to perform LDPC check matrix check on the received data. The UE performs FEC encoding on the CB, adds an error correction code to the CB, and performs rate matching on the additional CRC and the encoded CB to match the bearer capacity of the channel between the UE and the base station. After performing the rate matching, the UE sends the CB with the additional CRC, coding, and rate matching to the base station.

Correspondingly, the process of decoding and checking by the base station is shown in FIG. 4. The base station receives the data sent by the UE. The data may be an additional CRC, FEC encoding, and a rate-matched CB. The additional CRC, FEC encoding, and rate-matched CB are de-rate-matched to obtain a code to be decoded. Word, the coded codeword is an additional CRC and an encoded CB, and then the coded codeword is decoded to obtain a CB. The decoding result is then checked, and a specific checking method may be a CRC check. The CB is then reorganized to obtain a complete TB, that is, uplink data and uplink associated data. If the TB corresponding to the CB is not segmented, the CB does not need to be reorganized.

203. Determine the data carried in the uplink accompanying data. If only one of the downlink HARQ feedback and the CQI information is included, go to step 204. If the downlink HARQ feedback and the CQI information are included, go to step 206.

The base station determines data included in the uplink associated data, that is, downlink HARQ feedback and / or CQI information according to the analysis result of the uplink associated data.

204. An invalid value is included in one of the uplink accompanying data.

If the base station determines that the uplink accompanying data includes only one of the downlink HARQ feedback and the CQI information according to the analysis result, the base station may regard the one of the downlink HARQ feedback and the CQI information as an invalid value. Generally, if the base station only parses out that the uplink accompanying data only includes one of the downlink HARQ feedback and the CQI information, there may be data loss or data misalignment. Therefore, one of the downlink HARQ feedback and the CQI information may be Inaccurate, therefore, one of the downlink HARQ feedback and the CQI information is regarded as an invalid value. Avoiding that the base station cannot accurately process the next step due to misuse of invalid values can improve the reliability and processing efficiency of the base station. Avoid inaccurate calculation of channel quality by base stations, leading to downlink bit errors, affecting user rates and cell throughput rates

205. Determine the analysis result of the CQI information. If the analysis result is DTX, perform step 206; if the analysis result is non-DTX, perform step 208.

After determining that the analysis result of the uplink data is DTX, if the uplink accompanying data includes downlink HARQ feedback and CQI information, the base station analyzes the analysis result of the CQI information. If the analysis result of the CQI information is DTX, step 206 is performed, that is, it is determined that the downlink HARQ feedback result is DTX. If the analysis result of the CQI information is non-DTX, step 208 is performed.

206. Determine that the feedback result of the downlink HARQ feedback is DTX.

After determining that the analysis result of the uplink data is DTX, if the base station determines that the analysis result of the CQI information is DTX, that is, the received CQI information is empty, the base station can determine that the HARQ feedback is DTX, that is, the UE has not received the downlink data sent by the base station. .

Therefore, in order to avoid invalid downlink HARQ feedback retransmission, if the base station resolves that the downlink accompanying data includes downlink HARQ feedback and CQI information, and the analysis result of the CQI information is DTX, the base station can confirm that the downlink HARQ feedback is DTX, that is, the base station It is considered that the UE has not received downlink data.

In practical applications, if the base station parses in the uplink accompanying data to include both downlink HARQ feedback and CQI information, and the analysis result of the CQI information is DTX, that is, the CQI information is empty. Then, the base station may consider that the UE does not receive the downlink data or does not parse the downlink data. Therefore, the base station may determine that the downlink HARQ feedback is DTX. Correlation with the downlink HARQ feedback according to the analysis result of the CQI information can improve the efficiency of obtaining downlink HARQ feedback, improve the air interface resource utilization rate, and avoid invalid downlink HARQ feedback retransmission.

207. According to the feedback result of the downlink HARQ feedback, it is determined that the UE has not received the downlink data, and the downlink data is retransmitted.

After the base station confirms that the feedback of the downlink HARQ feedback is DTX, that is, after confirming that the UE has not parsed or received the downlink data, the base station can retransmit the downlink data.

It should be understood that after the base station determines that the feedback of the downlink HARQ feedback is DTX, in addition to retransmitting the downlink data, it can also perform other processes, such as sending query information to the UE or transmitting other data to the UE. limited. Therefore, step 207 is an optional step.

In the embodiment of the present application, after determining that the downlink HARQ feedback is DTX, that is, after determining that the UE has not received or parsed the downlink data, the base station may retransmit the downlink data. To avoid invalid downlink HARQ feedback retransmission, improve the efficiency of data transmission between the base station and the UE, and improve the utilization of air interface resources.

208: Use the demodulation result of the CQI information as the CQI value, and use the demodulation result of the downlink HARQ feedback as the feedback result.

After determining that the analysis result of the uplink data is DTX, if the base station determines that the analysis result of the CQI information is non-DTX, including ACK or NACK, the base station may use the demodulation result of the CQI information as the CQI value. The demodulation result of the CQI information is obtained by demodulating uplink associated data. The demodulation result of the downlink HARQ feedback is used as the feedback result of the downlink HARQ feedback.

Further, after the base station confirms the CQI value, the modulation mode and code rate of the data transmitted by the base station to the UE may be adjusted based on the CQI value. If the feedback result of the downlink HARQ feedback is DTX or NACK, the base station may perform retransmission or other processing on the downlink data. If the feedback result of the downlink HARQ feedback is ACK, the base station confirms that the UE has successfully received the downlink data, and the base station can perform corresponding processing.

In practical applications, if the base station resolves that the uplink associated data includes downlink HARQ feedback and CQI information, and the analysis result of the CQI information is non-DTX, then the analysis result of the uplink associated data is more accurate. If the downlink HARQ feedback and CQI information are discarded, invalid data retransmission and air interface resources will be wasted.

Therefore, in the embodiment of the present application, after determining that the analysis result of the uplink data is DTX, and the uplink accompanying data includes downlink HARQ feedback and CQI information, when the base station determines that the analysis result of the CQI information is non-DTX, the base station The demodulation result of the CQI information may be used as the CQI value, and the demodulation result of the downlink HARQ feedback may be used as the feedback result of the downlink HARQ feedback. Correlate the analysis result of the uplink data with the analysis result of the uplink associated data to quickly obtain the CQI value and the feedback result of the downlink HARQ feedback. Avoid invalid data retransmission and improve the efficiency of data transmission. It also improves the utilization of air interface resources, reduces the abnormal value of downlink misused channel quality, and reduces the call drop rate.

209. Perform other steps.

In this application, there are various situations for the analysis of uplink data. If the analysis result of the uplink data is non-DTX, that is, including ACK and NACK, it indicates that the UE has sent uplink data. At this time, if there is uplink associated data, including downlink HARQ feedback and / or CQI information, the uplink associated data can be directly analyzed, and the downlink HARQ feedback and / or CQI information can be directly processed according to the analysis result.

For example, if the CQI information is parsed to include the CQI value, the local CQI value of the base station may be directly updated through the CQI value. If the feedback result of the downlink HARQ feedback is parsed, it can be processed directly according to the feedback result. For example, if the feedback result of the downlink HARQ feedback is ACK, the base station determines that the UE has received the downlink data. If the feedback result of the downlink HARQ feedback is NACK or DTX, the base station may perform retransmission or other processing on the downlink data.

In the embodiment of the present application, the uplink data and the analysis result of the uplink associated data are correlated, and the downlink HARQ feedback and the analysis result of the CQI information are determined according to the result of the uplink data.
