Embodiment Construction

[0055] The application will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0056] In order to reduce the transmission delay and reduce the scheduling complexity, the radio access network (RAN, Radio Access Network) side introduces the CG of the uplink resources and the time advance value (TA value, Time Advance value), that is, configures the period for the terminal through the network side In this way, when the terminal is in the connected state, based on the configuration on the network side, the transmission block (TB) for transmitting uplink data is determined on the Physical Uplink Shared Channel (PUSCH, Physical Uplink Shared Channel). , Transport Block), and achieve time alignment with the network side. However, in related technologies, a terminal can only transmit uplink data when it is in a connected state, and when the terminal switches from a connected state to an inactive state, the terminal in the inactive sta...

Abstract

The invention discloses an uplink data transmission method and device, a terminal and a storage medium, and the method comprises the steps: transmitting uplink data based on first information under the condition that the terminal is in an inactive state; wherein the first information at least comprises CG information.

Description

technical field [0001] The present application relates to the communication field, and in particular to an uplink data transmission method, device, terminal and storage medium. Background technique [0002] In related technologies, when a terminal switches from a connected state (connected state) of Radio Resource Control (RRC) to an inactive state (inactive state), the terminal in the inactive state cannot perform uplink data transmission. Contents of the invention [0003] To solve related technical problems, embodiments of the present application provide an uplink data transmission method, device, terminal, and storage medium. [0004] An embodiment of the present application provides an uplink data transmission method applied to a terminal, including: [0005] When the terminal is in an inactive state, sending uplink data based on the first information; wherein, [0006] The first information includes at least configured grant (CG, Configured grant) information.
