It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
In one embodiment, as shown in fig. 1, a method for detecting downlink control information is provided, where this embodiment is applied to a terminal for illustration, it is understood that the method may also be applied to a server, and may also be applied to a system including a terminal and a server, and implemented through interaction between the terminal and the server. In this embodiment, the method includes the steps of:
step 102, obtaining downlink control information.
Illustratively, downlink control information, DCI (Downlink Control Information), transmitted from the base station is received.
And 104, detecting and judging the downlink control information according to a preset detection scheme and a preset detection threshold value, and obtaining a detection judgment result and detected downlink control information.
The preset detection scheme comprises a preset information processing algorithm.

The detection judging result comprises that only one downlink control information is detected and the number of the downlink control information is larger than one.
Illustratively, when the number of detected downlink control information is greater than one, the latest received downlink control information with the same format is retrieved from the historical downlink control information, and then the detected downlink control information is subjected to data processing based on the downlink control information with the same format and a preset data processing algorithm, so that an information calculation result corresponding to the detected downlink control information is obtained.

The preset information processing algorithm comprises a confidence coefficient calculation algorithm and a power calculation algorithm, and the preset detection threshold comprises a confidence coefficient threshold and a power threshold.
For example, when more than one downlink control information of the same format is determined, the power information of the downlink control information, i.e., the total power of the detection signal, is detected by the receiver. Then, confidence and power are needed to be calculated, and a specific calculation formula is as follows:

For example, bit information of the corresponding downlink control information when the data transmission decoding feedback is correct, that is, the downlink control information in the same format in the historical downlink control information, needs to be queried. In the course of the query, a timer is required.
If the query time length exceeds the preset query time length, setting the first received downlink control information in the detected downlink control information as target downlink control information.
In this embodiment, by searching for the historical downlink control information, in order to query the historical downlink control information with the same format as the detected downlink control information, when the same format cannot be searched, the first downlink control information received by the detected downlink control information with the same format is set as the target downlink control information, so as to reduce the probability of using the wrong downlink control information.

Wherein:
step 202, when the format search result is that the format of the existing historical downlink control information is the same as the format of the detected downlink control information, the same format historical information received in the previous time is selected.
For example, if the historical downlink control information with the same format as the detected downlink control information is retrieved within the preset retrieval time limit, the historical information which is the historical downlink control information with the same format and received last time is selected.
And 204, calculating the detected downlink control information according to the same format historical information and a preset data processing algorithm to obtain an information calculation result.
The preset data processing algorithm comprises bit sum operation and bit exclusive OR operation.
Illustratively, after the historical downlink control information is determined, bit information of the historical information and bit information of the detected downlink control information are utilized to carry out bit exclusive OR operation, then a result of the bit exclusive OR operation is subjected to bit sum operation, and further a bit sum operation result is obtained.
In this embodiment, by retrieving the historical downlink control information and then performing bit operation on the detected downlink control information by using the retrieved historical downlink control information, so as to obtain a bit and an operation result, it is possible to select the downlink control information more similar to the bit information of the historical downlink control information as the final scheduling downlink control information for use, so that the probability of using the erroneous downlink control information in this case is reduced.
In an exemplary embodiment, determining the target downlink control information based on the information calculation result includes:
numerical comparison is carried out on the information calculation results to obtain an information comparison result; determining an information calculation result corresponding to the minimum value based on the information comparison result; and determining the target downlink control information based on the information calculation result corresponding to the minimum value.
Illustratively, the detected downlink control information is compared with the bit and the operation result of the history information, the detected downlink control information with the smallest value is selected from the bit and the operation result, that is, the detected downlink control information corresponding to the smallest value in the bit and the operation result is selected, and the downlink control information is set as the target downlink control information. The specific simulation results are shown in fig. 3.
In this embodiment, the minimum value is selected from the bit and the operation result, that is, the downlink control information more similar to the bit information of the history downlink control information is selected as the final scheduling downlink control information for use, so that the probability of using the erroneous downlink control information in this case is reduced.
