摘要： A method and device for data transmission. The method comprises: a first device determines configuration information of a first resource, where the configuration information of the first resource comprises: cycle information of the first resource and information of the first resource; the first device transmits the configuration information of the first resource to multiple second devices; and the first device multicasts first information to the multiple second devices via the first resource. With the first device transmitting the first information to the multiple second devices in a multicasting manner, compared with the transmission of information in a unicasting manner, the redundancy of data transmitted is reduced, and the transmission efficiency is increased.

摘要： The present disclosure relates to communication technology, and provides a resource conflict handling method and apparatus, a terminal, and a storage medium. The method includes: transmitting, when a first Physical Uplink Control Channel (PUSCH) and a second PUSCH overlap or conflict with respect to time domain resources, if there is a fourth PUSCH in a third PUSCH included in the first PUSCH that does not overlap or conflict with the second PUSCH with respect to time domain resources, a data block over the fourth PUSCH. The first PUSCH is configured for repeated transmissions of the data block. In this way, the problem of conflict handling in the conflict scenario where the third PUSCH is present can be clarified. Here, available resources can be used as much as possible, and the resource utilization can be guaranteed, such that traffic can be transmitted to a network device as quickly as possible to avoid the delay caused by the resource conflict.

摘要： The present invention relates to the technical field of communications. Disclosed are a signal transmission method and apparatus, a mobile terminal, and a storage medium. The present solution comprises: when a conflict over transmission resources occurs, determining, according to transmission configuration information and resource indication information, a start position and/or an end position for signal processing in a first time-frequency resource; and performing signal processing on a first service signal according to the start position and/or the end position in the first time-frequency resource, so as to avoid mutual interference between the first service signal and a second service signal. The invention effectively solves the problem of uplink transmission conflicts between URLLC and eMBB while ensuring accurate signal transmission, and improves the efficiency of resource utilization.

摘要： A method for processing autonomous transmission of a User Equipment (UE), and a corresponding apparatus are provided. In the method, the UE receives first information transmitted by a network device. The first information includes autonomous transmission information, or information indicating activation or configuration of the autonomous transmission. The UE determines whether the autonomous transmission is configured or activated based on the first information. If it is determined from the first information that the autonomous transmission is configured or activated, the autonomous transmission is performed based on the first information. With the method, the autonomous transmission can be controlled based on the first information transmitted by a network, such that the implementation complexity of the UE can be reduced when the autonomous transmission of the UE and a network scheduled retransmission coexist, and the process is simple and clear, thereby reducing complexity of the UE and standardization work.
