As shown in fig. 2, a method for wireless transmission is provided in this embodiment, where the method is performed by an access network device, and the method includes:
step 21, sending downlink control information DCI to the terminal;
wherein, the information field of the DCI comprises:

The access network equipment involved in the present disclosure may be various types of base stations, for example, base stations of a fifth generation mobile communication (5G) network or other evolved base stations.
In one embodiment, downlink control information DCI is sent to a terminal; wherein, the information field of the DCI comprises: a first information field transmitted through a Physical Downlink Control Channel (PDCCH); and a second information domain transmitted through the Physical Downlink Shared Channel (PDSCH). Wherein the first information field indicates a first part of DCI information; the second information field indicates a second part of DCI information.
In one embodiment, the first portion of DCI information includes at least one of:
configuring frequency domain resources;
configuring time domain resources;
mapping information between a Virtual Resource Block (VRB) and a Physical Resource Block (PRB);
modulation coding scheme information;
a Hybrid Automatic Repeat Request (HARQ) process number;
the redundancy version RV.
In one embodiment, the second part of the DCI information includes at least one of:
downlink Assignment Index (DAI);
transmitting power control information of a physical uplink control channel;
physical uplink control channel resource indication information;
k1, K1 is an indication of the time length of the HARQ feedback distance PDSCH;
priority information;
channel access information.
In one embodiment, how the DCI contains information is allocated between the first information field and the second information field may be determined according to a coverage requirement parameter of the PDCCH transmission. Illustratively, if the coverage requirement parameter for PDCCH transmission is greater than a coverage threshold, the amount of information allocated to the first information domain may be less than a quantity threshold; alternatively, if the coverage requirement parameter for PDCCH transmission is less than the coverage threshold, the amount of information allocated to the first information field may be greater than the amount threshold.
It should be noted that information included in the first part of DCI information and information included in the second part of DCI information may be interchanged according to a scenario, and what kind of information specifically included in the first part of DCI information and the second part of DCI information is not limited in this disclosure, and the first part of DCI information and the second part of DCI information are not limited to include the above information, and may also include new addition information that occurs after network evolution.
It should be noted that, in the related art, the DCI transmitted in the PDCCH needs blind detection, and the size and aggregation level of different DCI loads affect the number of blind detections.
In one embodiment, downlink control information DCI is sent to a terminal; wherein, the information field of the DCI comprises: a first information field transmitted through a physical downlink control channel PDCCH; and a second information domain transmitted through a Physical Downlink Shared Channel (PDSCH). The payload size of the first information field is the same as the payload size of the first predetermined DCI format. Illustratively, the first predetermined DCI format includes at least one of: DCI format1_ 0; DCI format1_ 2.
It should be noted that, if the DCI format 0_0 is monitored in the common search space, and if the number of information bits in the DCI format 0_0 before padding is smaller than the payload size of the DCI format1_ 0 monitored in the common search space for scheduling the same serving cell, some zero padding bits are generated for the DCI format 0_0 until the payload size is equal to the size of the DCI format1_ 0.
Here, setting the payload size of the first information field to be the same as the payload size of the first predetermined DCI format may reduce the number of blind detections of the terminal. It should be noted that, when the payload size of the first information field is set to be the same as the payload size of the first predetermined DCI format, the number of blind detections of the terminal may be reduced, but the terminal cannot distinguish the format of the first information field from the first predetermined DCI format. Therefore, it is necessary to distinguish the format of the first information field from the first predetermined DCI format.
In one embodiment, downlink control information DCI is sent to a terminal; wherein, the information field of DCI includes: a first information field transmitted through a physical downlink control channel PDCCH; and a second information domain transmitted through the Physical Downlink Shared Channel (PDSCH). A payload size of the first information field is the same as a payload size of a first predetermined DCI format; a preset subdomain is arranged in the first information domain; the predetermined sub-field is used to indicate that the first information field is an information field indicating the first part of DCI. As such, in response to receiving DCI and determining that DCI is a first portion DCI based on a predetermined subfield, the terminal demodulates the second portion DCI information in the PDSCH scheduled by the PDCCH.
In one embodiment, downlink control information DCI is sent to a terminal; wherein, the information field of the DCI comprises: a first information field transmitted through a physical downlink control channel PDCCH; and a second information domain transmitted through the Physical Downlink Shared Channel (PDSCH). The load size of the first information field is a predetermined value. It should be noted that the predetermined value may be a value added to the load size value in the related art.
In one embodiment, downlink control information DCI is sent to a terminal; wherein, the information field of the DCI comprises: a first information field transmitted through a physical downlink control channel PDCCH; and a second information domain transmitted through the Physical Downlink Shared Channel (PDSCH).

Here, the second predetermined DCI format includes at least one of: DCI format1_ 0; DCI format1_ 1; DCI format1_ 2.
In one embodiment, downlink control information DCI is sent to a terminal; wherein, the information field of the DCI comprises: a first information field transmitted through a Physical Downlink Control Channel (PDCCH); and a second information domain transmitted through the Physical Downlink Shared Channel (PDSCH). The first information field has a payload size different from a payload size of a second predetermined DCI format. The kind of the DCI load size configured by the access network equipment and used for monitoring is smaller than a quantity threshold. In this way, after the format of the first information field is introduced, the types of the originally configured DCI payload sizes for monitoring can be reduced, thereby reducing the number of blind tests. The bits corresponding to the reduced DCI format may be different from the bits corresponding to the format of the first information field. As such, the types of DCI payloads that the search space can support are substantially reduced.
In one embodiment, the number threshold may be determined based on the number of blind tests required. Illustratively, in response to the required number of blind tests being less than a number threshold, the number threshold may be less than a predetermined value; alternatively, the number threshold may be greater than a predetermined value in response to the required number of blind tests being greater than the number threshold. In the present disclosure, the meaning of "less than" or "equal to" in some cases and the meaning of "greater than or equal to" in some cases are not limited herein.
In the embodiment of the disclosure, downlink control information DCI is sent to a terminal; wherein, the information field of DCI includes: a first information field transmitted through a Physical Downlink Control Channel (PDCCH); and a second information domain transmitted through the Physical Downlink Shared Channel (PDSCH). Here, since the DCI information field is divided into the first information field and the second information field, the first information field is transmitted through the PDCCH, and the second information field is transmitted through the PDSCH, compared with a method in which all the DCI is transmitted through the PDCCH, overhead of the DCI transmitted in the PDCCH can be reduced, coverage of PDCCH transmission is enhanced, and reliability of PDCCH transmission data is improved.
