Description

The present application claims priority to Chinese Patent Application No. 201910720250.5 filed with the China National Intellectual Property Administration (CNIPA) on Aug. 02, 2019. TECHNICAL FIELD The present application relates to the field of radio communication networks, for example, a radio resource configuration method and apparatus, and a storage medium. BACKGROUND Industrial Internet of Things (IIoT) services generally deliver machine instructions, those services are very sensitive to the delay, and service modes including the transmission cycle and the data packet size are determined. Such services need that a base station achieves accurate clock synchronization with a radio access network, and the services require a small transmission delay. To achieve the accurate clock synchronization between the base station and the radio access network, the base station needs to deliver accurate clock information to a terminal. How to indicate to the base station the clock synchronization requirement of the services carried by a terminal user equipment (UE) and achieve the accurate clock synchronization between the base station and the radio access network is an urgent problem to be solved. 3GPP Draft R3-191534, 3GPP Draft R3-192509, 3GPP Draft R3-191917, US 2019/166526 A1 and 3GPP Draft R2-1905647 are related prior art documents.
