Embodiment 1

[0132] This embodiment provides a DCI generation method. refer to figure 1 , the method for generating the DCI includes the following steps:

[0133] Step S101. Obtain the length of each field of the target DCI according to the length of each field of the expected DCI corresponding to the target cell. There are multiple target cells, the desired DCI is the DCI required for individually scheduling each target cell, and the length of each field of the target DCI is the length required to be compatible with the corresponding field of the desired DCI.

[0134] Step S102 , constructing subfields for each field of the target DCI according to a preset corresponding relationship so that each subfield of each field of the target DCI corresponds to a target cell.

[0135] Step S103: Generate each field of the target DCI according to the length of each field of the target DCI to form the target DCI.

[0136] According to the length of each field of the expected DCI corresponding to ea...

Embodiment 2

[0138] On the basis of Embodiment 1, this embodiment provides a DCI generation method.

[0139] As a specific implementation manner, in step S101, the length of the corresponding field of the target DCI is obtained according to the maximum value of the length of the corresponding field of the expected DCI.

[0140] Let the number of target cells be K. According to the prior art, in order to individually schedule the K target cells, the expected DCIs that need to be set separately, taking the frequency domain resource allocation fields as an example, the frequency domain resource allocation fields of these expected DCIs have corresponding length. In an optional implementation manner, the maximum value of these lengths is used as the length of the frequency domain resource allocation field of the target DCI. The method of determining the length of other fields of the target DCI is similar to this. Accordingly, the length of the generated target DCI can be compatible with the ...

Embodiment 3

[0150] On the basis of Embodiment 1, this embodiment provides a DCI generation method. In this embodiment, as a specific implementation manner, in step S101, the length of the corresponding field of the target DCI is obtained according to the sum of the lengths of the corresponding fields of multiple expected DCIs.

[0151] Let the number of target cells be K. According to the prior art, in order to individually schedule the K target cells, the expected DCIs that need to be set separately, taking the frequency domain resource allocation fields as an example, the frequency domain resource allocation fields of these expected DCIs have corresponding length. Let the length of the frequency domain resource allocation field of the expected DCI of the i-th target cell be W i (i∈[1,K]).

[0152] In an optional implementation manner, the length of the frequency domain resource allocation field of the target DCI In the frequency domain resource allocation field, the lowest W 1 b...

Abstract

The invention discloses a DCI generation method, a cell scheduling method, system and device, and a medium. The DCI generation method comprises the following steps: obtaining the length of each fieldof a target DCI according to the length of each field of an expected DCI corresponding to object cells, wherein the number of the object cells is not less than two, the expected DCI is the DCI required for separately scheduling each object cell, and the length of each field of the target DCI is the length required for being compatible with the corresponding field of the expected DCI; respectivelyconstructing sub-fields for each field of the target DCI according to a preset corresponding relation so as to enable each sub-field of each field of the target DCI to respectively correspond to one object cell; and generating each field of the target DCI according to the length of each field of the target DCI and the corresponding relation to form the target DCI. According to the invention, one target DCI is compatible with scheduling information of a plurality of cells.

Description

technical field [0001] The invention belongs to the technical field of downlink control information transmission, and in particular relates to a DCI (downlink control information) generation method, a cell scheduling method, a system, equipment and a medium. Background technique [0002] Currently, one DCI can only contain the scheduling information of one cell. For example, the scheduling DCI format in NR includes DCI0_0 / 0_1 / 0_2 / 1_0 / 1_1 / 1_2. Among them, DCI1_0 contains the following information: [0003] -DCI format identifier (Identifier for DCI formats)–1bits (bit) [0004] - frequency domain resource allocation in, Indicates the number of RBs included in the downlink BWP. In frequency domain resource allocation, resource allocation for uplink and downlink is the same. [0005] -Time domain resource assignment (Time domain resource assignment)–X bits [0006] -VRB-to-PRB mapping (VRB-to-PRB mapping)–1bit [0007] -Modulation and coding scheme (Modulation and co...
