Description

METHOD, APPARATUS AND SYSTEM FOR DATA TRANSMISSION This application claims the priority of U.S. Provisional Patent Application No. 63/526,094, filed on July 11, 2023, and of U.S. Provisional Patent Application No. 63/553,217, filed on February 14, 2024, the disclosures of which are incorporated, in their entireties, by this reference. TECHNICAL FIELD The present disclosure generally relates to the field of wireless communication, and in particular, to a method, apparatus and system for data transmission, and a computer readable storage medium. BACKGROUND In 4G and 5G, the BS and UE jointly perform the blind detection in PDCCH. The PDCCH blind detection schemes offers great flexibility in the system design, and utilize the downlink channel resource very efficiently. However, transmission of DCI is lack of flexibility. This background information is provided to reveal information believed by the applicant to be of possible relevance to the present disclosure. No admission is necessarily intended, nor should be construed, that any of the preceding information constitutes prior art against the present disclosure. SUMMARY According to a first aspect, a method for data transmission is provided. The method may be implemented by a transmitting apparatus, or modules in the transmitting apparatus (such as circuits, chips, or chip systems) , or logic nodes, logic modules, or software that may perform all or some of the functions of the transmitting apparatus. In an example where the method is applied to a transmitting apparatus, the method comprises: encoding information bits into a code block, wherein the code block includes one or more sub-code blocks; and transmitting the one or more sub-code blocks over one or more transmission resources, wherein the number of sub-code blocks are determined according to the number of one or more transmission resources. In this way, the number of sub-code blocks may be flexibly determined. In some embodiments, a number of the one or more sub-code blocks is equal to or a multiple of a number of transmission resources. In some embodiments, a number of transmission resources is equal to or a multiple of a number of the one or more sub-code blocks. In some embodiments, the sub-code block is a subset of code bits of the code block, and the sub-code block of the code block is a redundancy version (RV) of the code block. In some embodiments, at least one sub-code block is self-decodable, and the sub-code block  is a subset of code bits of length larger than a length of the information bits. In this way, the receiving device may decode the code block successfully without decoding the entire code block. In some embodiments, a first sub-code block and a second sub-code block include common bits. In this way, the receiving device may decode the code block successfully by decoding the first sub-code block or second sub-code block. In some embodiments, the one or more sub-code blocks are transmitted in downlink control channel, and number of the one or more transmission resources is an aggregation level (AL) of the downlink control channel. In some embodiments, the transmitting comprises: selecting a first number of transmission resources or a second number of transmission resources for transmitting the one or more sub-code blocks, wherein the first number of transmission resources is multiple of the second number of transmission resources, and a first resource of the first number of transmission resources is the same as a first resource of the second number of transmission resources, and a same sub-code block is mapped to both the first resource of the first number of transmission resources and the first resource of the second number of transmission resources. In this way, in a case where the code block is transmitted over the first number of transmission resources, the code block may be decoded successfully on the second number of transmission resources. Therefore, the code block may be decoded successfully at an earlier time. In some embodiments, the transmitting comprises: transmitting a first sub-code block on the first number of transmission resources or transmitting a second sub-code block on the second number of transmission resources, the second number of transmission resources is a subset of the first number of transmission resources, and the second sub-code block is a subset of the first sub-code block. In this way, in a case where the code block is transmitted over the first number of transmission resources, the code block may be decoded successfully on the second number of transmission resources. Therefore, the code block may be decoded successfully at an earlier time. In some embodiments, the same sub-code block is mapped to the first resource independent of the number of transmission resources. In this way, the code block may be decoded successfully at an earlier time. In some embodiments, the transmitting comprises: transmitting each sub-code block of the one or more su
