Method, user equipment, base station, device and medium for contention-based uplink data transmission

Abstract

The present disclosure relates to a communication method and system for converging a 5-Generation (5G) communication system for supporting higher data rates beyond a 4-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Embodiments of the present application provide a method, a UE, a base station, a device, and a computer-readable storage medium for contention-based uplink data transmission. A method for contention-based uplink data transmission comprises: receiving high layer configuration information for a contention-based physical uplink shared channel (PUSCH) transmission; monitoring first downlink control information (DCI) scrambled with a first radio network temporary identity (RNTI) in a first physical downlink control channel search space based on the high layer configuration information, and determining a contention-based PUSCH resource based on the detected first DCI; and transmitting data on the contention-based PUSCH resource. The present application improves the data transmission efficiency and reduces the UE's power consumption.
