Description

METHOD, APPARATUS AND SYSTEM FOR DATA TRANSMISSION This application claims the priority of U.S. Provisional Patent Application No. 63/513,046, 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. 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 a first set of code bits for a first data transmission over a first set of time domain resources and a first set of frequency domain resources; and receiving first control information corresponding to the first set of code bits over a second set of time domain resources and a second set of frequency domain resources; wherein at least some time resources of the first set of time domain resources and the second set of time domain resources are overlapped, and at least some frequency resources of the first set of frequency domain resources and the second set of frequency domain resources are overlapped. In such case, the resources for sending the first set of code bits for a first data transmission and the resources for receiving the first control information corresponding to the first set of code bits are at least partially overlapped, and transmitting apparatus may receive the first control information in a timely manner. In some embodiments, the method further comprises: sending an indication of the first set of time domain resources and the second set of time domain resources. In this way, the receiving apparatus will know on which resources it may receive the first set of code bits for the first data transmission and on which resources it may send the first control information. In some embodiments, the indication further indicates one or more time domain resources for receiving the first control information corresponding to the first set of code bits, and the one or more time domain resources belongs to the second set of time domain resources. In this way, the receiving apparatus will know on which resources of second set of time domain resources it may send the first control information. In some embodiments, the first control information further indicates that the first control information corresponds to the first set of code bits. In this way, the receiving apparatus will know which set of code bits the first control information corresponds to. In some embodiments, the method further comprises: sending a second set of code bits for a second data transmission over the first set of time domain resources; and receiving second control information corresponding to the second set of code bits over the second set of time
