Description

METHOD, APPARATUS AND SYSTEM FOR DATA TRANSMISSION This application claims the priority of U.S. Provisional Patent Application No. 63/526,073, filed on July 11, 2023, the disclosure of which is incorporated, in its entirety, 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 Two trends are observed toward 6G, one is the ever-crowded spectrum in the sub-3G bands, and the ever-increasing power saving demand. The past generations of mobile communications (4G and 5G) have adopted higher frequency spectrums for larger bandwidth. However, due to the channel propagation characteristics, the coverage is much smaller than lower-frequency bands, say, sub-3GHz. The power efficiency is also much lower. As a result, the operators are more willing to prioritize the use of lower bands for better coverage and power saving. As a result, the sub-3Ghz bands will become even more crowded. A key target of 6G is to reduce the global carbon footprint, at least does not increase the net energy consumption of 5G. However, denser deployment of wireless devices is expected, which naturally increases the inter-cell and inter-device interference. Reducing the transmit energy will have the double benefits of energy saving and interference mitigation, however at the cost of lower received signal-to-interference-plus-noise ratio (SINR) . This is a dilemma. With the current technology, there are several schemes to save transmission energy, improve spectral efficiency and enhance SINR. The first scheme is link adaptation and Hybrid automatic repeat request (hybrid ARQ or HARQ) , and the second scheme is power adaptation. 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: mapping one or more sub-code blocks of one or more first codewords  to one or more time and frequency resources, wherein the one or more sub-code blocks are interleaved; and sending one or more second codewords, wherein the one or more second codewords include at least one of the one or more sub-code blocks. In such case, after being interleaved, the sub-code blocks will be mapped to time and frequency resources in a more dispersed manner. Therefore, the sub-code blocks may be mapped to time and frequency resources in a flexible way. In some embodiments, the one or more sub-code blocks correspond to one or more feedback opportunities, and wherein a feedback of at least one of the one or more feedback opportunities indicates a decoding result of the one or more first codewords. Since the sub-code blocks may be spread on the time resources, there will be more opportunity for the receiving apparatus to feedback. Thereby, the receiving apparatus may transmit the feedbacks timely. In some embodiments, initial sub-blocks of at least two different first codewords are mapped to a same time resource. In such case, the initial sub-blocks of the at least two different first codewords may be transmitted at the same time. Accordingly, the initial sub-blocks of the at least two different first codewords may be received and decoded at the same time. In this way, the two different first codewords may be decoded at an early time. In some embodiments, at least two sub-blocks of two different first codewords are mapped to a same time resource. In such case, the sub-blocks of the at least two different first codewords may be transmitted at the same time. Accordingly, the sub-blocks of the at least two different first codewords may be received and decoded at the same time. In this way, the two different first codewords may be decoded at an early time. In some embodiments, at least two sub-blocks of two different first codewords are mapped to an equal number of frequency resources. In some embodiments, the one or more sub-blocks are interleaved such that the one or more sub-blocks are mapped one by one. In such case, after being interleaved, the sub-code blocks will be mapped to time and frequency resources in a more dispersed manner. Therefore, the sub-code blocks may be mapped to time and frequency resources in a flexible way. In some embodiments, the one or more sub-blocks are interleaved includes: the one or more sub-bloc
