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, 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 With the current technology, there are several schemes for resource allocation. One scheme is pre-emption transmission. During pre-emption transmission, the incumbent Enhanced Mobile Broadband (eMBB) transmission may be punctured by an Ultra-reliable and Low Latency Communications (URLLC) packet. In such case, the successful decoding of the incumbent transmission may not be guaranteed. Another scheme is contention-based transmission. During contention-based transmission, the users may perform listen-before-talk, which means if an incumbent transmission is detected, the user needs to back off and wait for available resource. However, different transmission are likely to collide during contention-based transmission. 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. 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: transmitting information indicating a first set of resources and a second set of resources, the first set of resources for transmitting the first data transmission, and the second set of resources for transmitting the second data transmission, wherein the first set of resources and the second set of resources are at least partially overlapped; transmitting the first data transmission on the first set of resources; and transmitting the second data transmission on the second set of resources in a case where a condition is satisfied; wherein the condition includes at least one of: detecting a first signal indicating the second data transmission is to be transmitted on the second set of resources; detecting a second signal indicating the first data transmission is stopped; receiving a feedback indicating the first data is successfully decoded; a priority of the second data transmission is higher than a priority of the first data transmission; or a channel quality of a channel for transmitting the second data transmission is above a threshold. In such case, conditions may be set for data transmission so that data transmission on resources which are overlapped may be conditionally scheduled. In this way, the transmitting apparatus may determine which data to be transmitted over the overlapped resources. The data transmission that is more important or urgent may be preferentially transmitted over the overlapped resources. In some embodiments, the method further comprises: transmitting a first indication enabling receiving of the second data transmission on the second set of resources in the case where the condition is satisfied. In this way, the transmitting apparatus may enable the receiving apparatus to adopt the method by transmitting the first indication. In some embodiments, the method further comprises: transmitting a third signal indicating the second data transmission is to be transmitted on the second set of resources or the second data transmission is being transmitted on the second set of resources. In this way, the transmitting apparatus may inform the receiving apparatus whether the second data transmission is to be transmitted or being transmitted on the second set of resources. In some embodiments, the transmitting the third signal comprises: transmitting the third signal in the case where the condition is satisfied. In some embodiments, the priority of the first data transmission and the priority of the second data transmission are each indicated by a respective priority index. Alternatively, the priority of the first data transmission and the priority of the second data transmission may be each indicated by a respective priority ID. In some embodiments, the priority of the first data transmission is based on at least one of: a payload content of the first data transmission, a channel quality of a channel for transmitting the first data transmission, a transmission mode for transmitting the first data transmission, a bandwidt
