The present application provides a transmission method, a terminal device and a network device, so that the network device can determine the number of current authorization-free transmissions of the terminal device. The method includes: the terminal device determines K groups of resources for authorization-free transmission, the K groups of resources do not overlap each other, and K is the maximum number of times of authorization-free repeated transmission; The corresponding relationship of transmission, in each of the m consecutive authorization-free transmission periods starting from the first authorization-free transmission period, the first transmission block is transmitted; wherein, K times of authorization-free repeated transmission of the same transmission block It is carried out in K consecutive authorization-free transmission periods, and the same transmission block is transmitted once in each authorization-free transmission period. Each authorization-free transmission period includes K groups of resources, and each group of resources in the K groups of resources uses One of the K unlicensed retransmissions of the same transmission block.
Description
technical field [0001] The present application relates to the communication field, and more specifically, to a transmission method, terminal equipment and network equipment. Background technique [0002] The fifth generation (the 5 th Generation, 5G) wireless communication standards, in order to support Ultra-Reliability Low Latency Communication (URLLC) services, it is proposed to use license-free transmission technology, that is, network equipment (such as base station (Base Station, BS)) in advance Arrange a shared contention-based transmission area (Contention-based Transmission Area, CTA), the CTA appears in each license-free transmission period, when the terminal equipment UE has data to send, immediately in the CTA of the latest license-free transmission period Randomly select one or more contention-based transmission units (Contention-based Transmission Unit, CTU) to transmit data. Because the UE does not request the BS to allocate resources before transmitting da...
