Abstract

Embodiments of the present application provide a data transmission method, a communication device, and a storage medium. In a scenario of frequency domain resources such as multiple CCs, when a terminal device uses a configuration authorization resource on one of the frequency domain resources (such as a CC) to send uplink data, The UCI may be used to indicate to the network device the configuration authorization resource used when the terminal device sends uplink data. In this way, when the network device does not correctly receive the uplink data sent by the terminal device when the authorized resource is configured, it can schedule the terminal device to retransmit data on the frequency domain resources corresponding to the configured authorized resource according to the UCI, ensuring the transmission of uplink data While improving reliability, the resource overhead of data retransmission is reduced.

Description

technical field [0001] The embodiments of the present application relate to communication technologies, and in particular, to a data transmission method, a communication device, and a storage medium. Background technique [0002] The future 5G communication system introduces the concept of a periodic configured grant (CG). After the network device configures the configuration authorization resource for the terminal device and activates the terminal device to use the configuration authorization resource, the terminal device can use the configuration authorization resource to send ultra-reliable and low latency communications (URLLC) to the network device business data. In the prior art, if the network device does not correctly receive the URLLC service data sent by the terminal device using the configuration authorization resource, and does not de-identify the terminal device, the network device cannot know that the terminal device has sent data. In this scenario, the netwo...
