Description

METHOD, APPARATUS AND SYSTEM FOR DATA TRANSMISSION This application claims the priority of U.S. Provisional Patent Application No. 63/513,043, filed on July 11, 2023, and U.S. Provisional Patent Application No. 63/513,040, filed on July 11, 2023, the disclosure of each of which are 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. The link adaptation and HARQ methods suffer from low spectrum efficiency and excessive latency. The power adaptation suffers from low spectrum efficiency and low power efficiency. 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: sending one or more sets of bits of a first codeword on a first resource; sending one or more sets of bits of a second codeword on a first part of a second resource; sending one or more sets of bits of the first codeword on a second part of the second resource; receiving feedback indicating the first codeword is decoded successfully; and terminating the sending of the one or more sets of bits of the first codeword in response to the feedback. In such case, the transmission of the first codeword may occupy the first resource and a part of the second resource. The transmission of the second codeword may be punctured by the transmission of the first codeword. In this way, if the first codeword is not successfully decoded by the end of the first resource, the first codeword will be opportunistically transmitted on other resources, and the transmission of the first codeword will not be limited within the first resource. Therefore, there will be more opportunities for transmission of the first codeword, and the possibility of decoding the first codeword successfully at the receiving apparatus will be increased. In some embodiments, the method further comprises: sending a first indication for indicating at least one of: a proportion of the second part of the second resource in the second resource, a quantity of the second part of the second resource, or a distribution of the second part of the second resource in the second resource. In this way, the transmitting apparatus may inform the receiving apparatus of the information about the second part of the second resource, and the receiving apparatus may know on which resource it will receive the first codeword. In an implementation, the second part of the second resource is evenly distributed in the second resource; or, the second part of the second resource is distributed at the beginning of the second resource, at the end of the second resource, or at both the beginning and end of the second resource. In this way, the transmitting apparatus may inform the receiving apparatus of the distribution of the second part of the second resource in the second resource. In some embodiments, the second part
