All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the disclosure, are within the scope of the disclosure.
The embodiment of the disclosure provides an information verification method which is applied to a receiving end to verify downlink control information transmitted by a base station and is implemented in equipment of the receiving end. The device of the receiving end can be in various implementation forms, such as a mobile phone, a tablet computer, a computer and the like, and the protection scope of the present disclosure is not limited by the specific implementation form of the receiving end device.
In one embodiment, as shown in fig. 1, the main flow steps of the information verification method are as follows:
step 101, obtaining target downlink control information.
In one embodiment, target Downlink Control Information (DCI) is acquired through a PDCCH. After the PDCCH is established between the base station and the receiving end, the base station transmits the DCI to the receiving end through the PDCCH, so that the receiving end obtains the target DCI.
Step 102, according to the target downlink control information, acquiring first resource grid energy used by the physical downlink shared channel to transmit data, and acquiring second resource grid energy used by the reference signal and corresponding to the physical downlink shared channel to transmit data.
In one embodiment, as shown in fig. 2, for a time-frequency resource with a length of one subframe, an area corresponding to the 1 st to 3 rd orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, abbreviated as OFDM) symbols in the left side of fig. 2 is a control area, and control information is mainly transmitted, where the control information includes DCI. The region corresponding to the 4 th to 14 th OFDM symbols from the left side in fig. 2 is a data region, and is a region where PDSCH data is located. In addition, cell reference signals (Cell-SPECIFIC REFERENCE SIGNAL, abbreviated CRS) are regularly distributed over the entire resource grid.
Each grid in the figure represents one Resource Element (RE), which is the smallest Resource unit in the LTE physical Resource, occupies 1 subcarrier (15 KHz) in the frequency domain, and occupies 1 OFDM symbol (1/14 ms) in the time domain. In the LTE system, the frequency domain basic scheduling unit of the data channel Resource allocation is a Resource Block (RB), and the RB frequency domain occupies 12 subcarriers. As shown in fig. 2, in the present embodiment, the 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 the present disclosure is not limited by the number of OFDM symbols included in the RB time domain.
In this embodiment, when the data region has no other resources than CRS allocated, it is obvious that the energy on other REs is significantly lower than the signal energy on the corresponding position of CRS. Therefore, the DCI designates the resource grid energy corresponding to the PDSCH data, and the DCI is compared with the resource grid energy of the reference signal to determine whether the PDSCH exists or not, thereby further determining whether the DCI is valid or not.
In one embodiment, according to the target downlink control information, the specific process of acquiring the first resource grid energy for transmitting data (PDSCH data for short) of the physical downlink shared channel and the second resource grid energy for transmitting the reference signal corresponding to the data transmitted by the physical downlink shared channel is as follows:

And acquiring reference signal position information occupied by a reference signal (namely CRS) corresponding to physical downlink shared channel transmission data, and acquiring second resource grid energy used by the reference signal according to the reference signal carried by the reference signal position information.
In this embodiment, a first set of time-frequency resource locations of PDSCH data is obtained through DCI, where the first set is denoted by { L PSDCH,KPDSCH }, where L represents location information of a sub-carrier signal in the frequency domain, and K represents a Single-carrier frequency division multiple access (SC-Division Multiple Access, abbreviated as SC-FDMA) sequence number in the time domain. Each set of location information combinations in the first set, i.e. representing one RE in the resource grid, is data location information. According to the first set of time-frequency resource positions, the energy of RE used by each PDSCH data is calculated, and the specific calculation process is as follows:
Wherein, the Representative is the energy of the RE whose position information is (l, k) in PDSCH data.
And obtaining the first resource grid energy used by all the PDSCH data through the first set of the time-frequency resource positions of the PDSCH data and the energy corresponding to each position in the first set.
In this embodiment, a second set of time-frequency resource locations of CRS is obtained through DCI, where the second set is denoted by { L CRS,KCRS }. The second set { L CRS,KCRS } is similar to the meaning of the letters in the first set { L PSDCH,KPDSCH }, and will not be described in detail here. The second set is the reference signal position information. According to the second set of time-frequency resource positions, the energy of RE used by each CRS data is calculated, and the specific calculation process is as follows:
Wherein, the Representative is the energy of REs whose position information is (l, k) in CRS data.
And obtaining second resource grid energy used by all the CRS data through the second set of time-frequency resource positions of the CRS data and the energy corresponding to each position in the second set.

In this embodiment, according to the target downlink control information, the number of RBs occupied by PDSCH data may be determined to be N. And obtaining the energy corresponding to each RB occupied by the PDSCH data according to the energy corresponding to each RE occupied by the PDSCH data obtained through calculation. Specifically, the calculation process of the occupation energy of PDSCH data contained in the ith RB of the N RBs is as follows:
Wherein, the I.e., represents the energy occupied by PDSCH data contained in the i-th RB.
After determining that the number of RBs occupied by PDSCH data is N, according to the energy corresponding to each RE occupied by CRS data obtained by the calculation, the energy corresponding to CRS data in each RB may be obtained. Specifically, the calculation process of the occupation energy of PDSCH data contained in the ith RB of the N RBs is as follows:

The specific process of verifying the validity of the target downlink control information according to the comparison results is as follows, and the validity of the target downlink control information is verified according to the N comparison results. Namely, the ith RB in the N RBs is corresponded toAnd (3) withAnd comparing to obtain N comparison results, and then verifying the validity of the target downlink control information according to the N comparison results.
In one embodiment, an energy scaling factor is used to eliminate the impact of objective conditions on energy computation. And comparing the first resource grid energy and the second resource grid energy corresponding to each resource block respectively to obtain N comparison results, wherein the specific process is as follows as shown in fig. 3:

By the energy scaling factor, the difference between the energy of the first resource grid and the energy of the second resource grid caused by objective conditions can be avoided, an accurate comparison result is obtained, and the robustness of the comparison result is enhanced. It should be noted that, the energy scaling factor may be valued according to the needs and actual situations, and the protection scope of the present disclosure is not limited by the method of the energy scaling factor.
In one embodiment, the energy scaling factor is preferably set to 0.2.
