Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of communications, and in particular to an information verification method, apparatus, device, and storage medium. Background Art
[0002] In the Long Term Evolution (LTE) system based on Time Division Duplex (TDD), service data is primarily transmitted on the Physical Downlink Shared Channel (PDSCH). To correctly receive PDSCH data, it is necessary to first correctly receive the Downlink Control Information (DCI) transmitted on the Physical Downlink Control Channel (PDCCH). DCI provides the necessary information for decoding data such as the resource location corresponding to the PDSCH.
[0003] In the prior art, a cyclic redundancy check (CRC) is performed on the PDCCH that transmits DCI. This is done by confirming the DCI length and other methods to determine whether the DCI is correctly parsed, thereby determining whether to further decode the PDSCH data. However, it is impossible to receive any signal completely correctly, especially in poor channel conditions. If a false alarm occurs in the received DCI—that is, the base station does not configure the DCI, but the receiving end interprets it as DCI, or the base station configures the DCI but the receiving end fails to detect a decoding error, or the receiving end is unable to obtain the relevant parameters for the CRC check—the receiving end will further decode the PDSCH data according to the location information configured in the DCI. In this case, since the DCI is incorrect, the decoded PDSCH data is inevitably incorrect. This not only results in a large amount of wasted time and resources due to ineffective calculations, but also causes errors in the transmitted PDSCH data, further reducing data transmission efficiency.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.
[0026] The present disclosure provides an information verification method for verifying downlink control information transmitted by a base station at a receiving end. The method is implemented within a receiving device. The receiving device can be implemented in various forms, such as a mobile phone, tablet computer, or computer. The scope of protection of the present disclosure is not limited to the specific implementation form of the receiving device.
[0027] In one embodiment, Figure 1 As shown, the main process steps of the information verification method are as follows:
[0028] Step 101: Acquire target downlink control information.
[0029] In one embodiment, target downlink control information (DCI) is obtained via PDCCH. After PDCCH is established between the base station and the receiving end, the base station transmits DCI to the receiving end via PDCCH, so that the receiving end obtains the target DCI.
[0030] Step 102: According to the target downlink control information, a first resource grid energy used for transmitting data on a physical downlink shared channel is obtained, and a second resource grid energy used for a reference signal corresponding to the physical downlink shared channel transmission data is obtained.
[0031] In one embodiment, the LTE resource grid is distributed as follows: Figure 2 As shown, for a time-frequency resource with a length of one subframe, Figure 2 The region corresponding to the 1st to 3rd Orthogonal Frequency Division Multiplexing (OFDM) symbols from the left side is the control region, which mainly transmits control information, including DCI. Figure 2The area corresponding to the 4th to 14th OFDM symbols from the left in the middle is the data area, which is where the PDSCH data is located. In addition, the cell-specific reference signal (CRS) is regularly distributed throughout the resource grid.
[0032] Each grid in the figure represents a resource element (RE), which is the smallest resource unit in LTE physical resources. It occupies one subcarrier (15KHz) in the frequency domain and one OFDM symbol (1 / 14ms) in the time domain. In the LTE system, the basic scheduling unit for data channel resource allocation in the frequency domain is the resource block (RB), which occupies 12 subcarriers in the frequency domain. Figure 2 As shown, in this embodiment, an RB is defined to include 14 OFDM symbols in the time domain. It should be noted that the number of OFDM symbols included in the RB time domain is not fixed, and the protection scope of this disclosure is not limited to the number of OFDM symbols included in the RB time domain.
[0033] In this embodiment, when no resources other than the CRS are allocated in the data region, it is obvious that the energy on other REs is significantly lower than the signal energy at the corresponding CRS position. Therefore, by comparing the resource grid energy corresponding to the PDSCH data specified by the DCI with the resource grid energy of the reference signal, it is possible to determine whether the PDSCH exists and further determine whether the DCI is valid.
[0034] In one embodiment, according to the target downlink control information, a first resource grid energy used for physical downlink shared channel transmission data (PDSCH data for short) is obtained, and a second resource grid energy used for a reference signal corresponding to the physical downlink shared channel transmission data is obtained. The specific process is as follows:
[0035] Based on the target downlink control information, data location information in the resource grid occupied by the physical downlink shared channel transmission data is determined, and based on the data carried by the data location information, a first resource grid energy is obtained. Reference signal location information occupied by the reference signal (i.e., CRS) corresponding to the physical downlink shared channel transmission data is obtained, and based on the reference signal carried by the reference signal location information, a second resource grid energy used by the reference signal is obtained.
[0036] In this embodiment, the first set of time-frequency resource locations of PDSCH data is obtained through DCI, and the first set is represented by {L PSDCH ,K PDSCH} represents, where L represents the location information of the sub-wavelength carrier signal in the frequency domain, and K represents the single-carrier frequency division multiple access (SC-FDMA) sequence number in the time domain. Each combination of location information in the first set represents an RE in the resource grid, and the first set is the data location information. Based on the first set of time-frequency resource locations, the energy of the RE used for each PDSCH data is calculated. The specific calculation process is as follows:
[0037]
[0038] in, It represents the energy of the RE with location information (l, k) in the PDSCH data.
[0039] The first resource grid energy used by all PDSCH data can be obtained through the first set of time-frequency resource positions of the PDSCH data and the energy corresponding to each position in the first set.
[0040] In this embodiment, the second set of time-frequency resource locations of CRS is obtained through DCI, and the second set is represented by {L CRS ,K CRS} represents the second set {L CRS ,K CRS} and the first set {L PSDCH ,K PDSCH The letters in} have similar meanings and are not repeated here. The second set is the reference signal location information. Based on the second set of time-frequency resource locations, the energy of the RE used for each CRS data is calculated. The specific calculation process is as follows:
[0041]
[0042] in, It represents the energy of the RE with location information (l, k) in the CRS data.
[0043] The second resource grid energy used by all CRS data can be obtained through the second set of time-frequency resource positions of the CRS data and the energy corresponding to each position in the second set.
[0044] In one embodiment, data location information in a resource grid used for transmitting data on a physical downlink shared channel is determined based on target downlink control information, and a first resource grid energy is obtained based on the data carried by the data location information. This specifically includes the following processes: determining N resource blocks occupied by the physical downlink shared channel for transmitting data based on the target downlink control information, where N is an integer greater than 1; and obtaining N first resource grid energies corresponding to the N resource blocks and used for transmitting data on the physical downlink shared channel based on the data location information in the resource grid occupied by the physical downlink shared channel.
[0045] In this embodiment, reference signal position information occupied by a reference signal corresponding to physical downlink shared channel transmission data is obtained, and a second resource grid energy used by the reference signal is obtained based on the reference signal carried by the reference signal position information. This specifically includes the following process: based on the reference signal position information occupied by the reference signal corresponding to physical downlink shared channel transmission data, N second resource grid energies used by the reference signal corresponding to N resource blocks are obtained.
[0046] In this embodiment, based on the target downlink control information, the number of RBs occupied by the PDSCH data can be determined to be N. Based on the energy corresponding to each RE occupied by the PDSCH data obtained by the above calculation, the energy corresponding to each RB occupied by the PDSCH data can be obtained. Specifically, the calculation process of the energy occupied by the PDSCH data contained in the i-th RB among the N RBs is as follows:
[0047]
[0048] in, That is, it represents the energy occupied by the PDSCH data contained in the i-th RB.
[0049] After determining that the number of RBs occupied by PDSCH data is N, the energy corresponding to each RE occupied by CRS data obtained by the above calculation can be used to obtain the energy corresponding to the CRS data in each RB. Specifically, the calculation process for the energy occupied by PDSCH data contained in the i-th RB among N RBs is as follows:
[0050]
[0051] in, That is, it represents the energy occupied by the CRS data contained in the i-th RB.
[0052] Step 103: Compare the first resource grid energy and the second resource grid energy to obtain a comparison result.
[0053] In one embodiment, after determining N RBs according to the target downlink information, the first resource grid energy and the second resource grid energy are compared to obtain the comparison result in the following specific process: the first resource grid energy and the second resource grid energy corresponding to each resource block are compared to obtain N comparison results. The specific process of verifying the validity of the target downlink control information according to the comparison results is as follows: verifying the validity of the target downlink control information according to the N comparison results. That is, the energy corresponding to the i-th RB in the N RBs is compared to obtain N comparison results. and Perform comparisons to obtain N comparison results, and then verify the validity of the target downlink control information based on the N comparison results.
[0054] In one embodiment, an energy scaling factor is used to eliminate the influence of objective conditions on energy calculation. The first resource grid energy and the second resource grid energy corresponding to each resource block are compared to obtain N comparison results, such as Figure 3 The specific process is as follows:
[0055] Step 301, obtaining a preset energy scaling factor;
[0056] Step 302 , multiplying the second resource grid energy corresponding to each resource block by the energy scaling factor to obtain N scaled second resource grid energies;
[0057] Step 303 : Compare the first resource grid energy corresponding to each resource block with the second resource grid energy to obtain N comparison results.
[0058] In this embodiment, the energy scaling factor is a real number greater than 0 and less than 1. The energy scaling factor can avoid differences in the energy of the first resource grid and the energy of the second resource grid caused by objective conditions, resulting in accurate comparison results and enhancing the robustness of the comparison results. It should be noted that the energy scaling factor can be determined based on needs and actual conditions, and the scope of protection of this disclosure is not limited to the method for determining the value of the energy scaling factor.
[0059] In one embodiment, preferably, the energy scaling factor is set to 0.2.
[0060] Step 104: Verify the validity of the target downlink control information based on the comparison result.
[0061] In one embodiment, Figure 4 As shown, based on the comparison result, the validity of the target downlink control information is verified. The specific process is as follows:
[0062] Step 401, obtaining a threshold value of the number of comparison results that meet a preset condition;
[0063] Step 402: determine whether the number of N comparison results that meet the preset conditions is greater than the number threshold. If so, execute step 403; if not, execute step 404.
[0064] Step 403: Determine whether the target downlink control information is valid;
[0065] Step 404: Determine that the target downlink control information is invalid.
[0066] In one embodiment, during the actual transmission process of a signal, there is the influence of other interfering signals, which may cause the received data to be missed. Therefore, a corresponding fault tolerance method should be used to avoid this situation.
[0067] In this embodiment, the influence of interference signals is eliminated by setting the number threshold to a relevant empirical coefficient. Figure 5 As shown, the process of obtaining the number threshold of comparison results that meet the preset conditions is as follows:
[0068] Step 501, obtaining an empirical coefficient that the comparison result meets a preset condition;
[0069] Step 502: multiply N by the empirical coefficient to obtain a threshold value of the number of comparison results that meet the preset conditions.
[0070] In this embodiment, the empirical coefficient can be set based on experience and actual conditions, or can be obtained through calculation using a specific algorithm. The scope of protection of the present disclosure is not limited to the method of generating the empirical coefficient.
[0071] In one embodiment, preferably, the empirical coefficient is 0.2.
[0072] The information verification method provided by the present disclosure obtains the first resource grid energy used for physical downlink shared channel (PDSCH) data transmission based on the target downlink control information, as well as the second resource grid energy of the reference signal corresponding to the physical downlink shared channel data transmission. The first resource grid energy and the second resource grid energy are compared to determine the validity of the target downlink control information. This method can accurately determine the validity of the downlink control information based on the resource grid energy, avoiding PDSCH data decoding errors caused by invalid downlink control information, thereby avoiding the waste of time and resources caused by invalid decoding calculations, and further improving data transmission efficiency.
[0073] At the same time, by comparing the first resource grid energy and the second resource grid energy corresponding to each RB respectively, and setting the energy scaling factor and the empirical coefficient, the accuracy of the energy comparison process can be improved, the interference caused by the objective factors of the interference signal can be filtered out, and the reliability of the information verification process can be improved.
