Abstract
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides a grant-free data transmission method. The method includes: receiving resource allocation information for grant-free transmission from a base station; when there is data to be transmitted in a grant-free transmission mode, transmitting uplink data using the grant-free transmission resources according to the resource allocation information; if the transmission of the uplink data cannot be completed within a predefined number of uplink data transmissions, transmitting a dedicated resource request indicator to the base station; receiving dedicated resource allocation information from the base station; and transmitting subsequent uplink data on dedicated resources corresponding to the dedicated resource allocation information. The present disclosure further provides a grant-free data transmission method applied to the base station, a UE and a base station. The technical solution of the present disclosure can improve the data transmission re…
