Abstract

The embodiment of the invention provides a data transmission method and device, and the method comprises the steps: dividing a first PUSCH transmission symbol into at least two second PUSCH transmission symbols when the first PUSCH transmission symbol comprises a downlink symbol or a symbol which cannot be used for PUSCH transmission; when a second PUSCH transmission symbol satisfying a first condition exists in the at least two second PUSCH transmission symbols, sending the second PUSCH transmission symbol satisfying the first condition to a network device. According to the method, when a downlink symbol is included in a first PUSCH transmission symbol, the first PUSCH transmission symbol is divided, and the divided second PUSCH transmission symbol meeting the first condition is sent to the network device so that the problem that the repetition frequency is influenced due to the fact that the PUSCH is not transmitted directly when the first PUSCH transmission symbol comprises the downlink symbol is avoided, and the uplink coverage is effectively ensured.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a data transmission method and device. Background technique [0002] 5G New Radio (New Radio, NR) supports a flexible frame structure, and can indicate uplink symbols, downlink symbols or flexible symbols in the frame structure through slot format information (SlotFormat related Information, SFI). [0003] At present, 5G NR supports repeated transmission within a time slot and repeated transmission between time slots. In the process of realizing repeated transmission, the network device can configure the number of repetitions to the terminal device, so that the terminal device can perform PUSCH (Physical Uplink Shared) according to the number of repetitions. Channel, physical uplink shared channel) repeated transmission. [0004] However, when the transmission symbols of the PUSCH include DL symbols or symbols not available for PUSCH transmission, the PUSCH...
