In this way, configuration grant based small data transmission can be enhanced.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A method comprises a terminal device determines whether one or more DRBs with uplink data to be transmitted support SDT. If the one or more DRBs support the SDT, the terminal device determines whether the uplink data is to be transmitted in the inactive state. If the uplink data is to be transmitted in the inactive state, the terminal device transmits the uplink data to a first network device in the inactive state.

In this way, an enhanced mechanism for SDT is achieved and lossless transmission for SDT is attained.
