The data segment is transmitted after performing the Random Access Channel (RACH) procedure
By receiving PDCCH configuration and dynamic scheduling information during the RACH process, the efficiency problem of small data transmission in the RRC inactive state in 5G NR is solved, and efficient data segment transmission is achieved, which is suitable for scenarios such as enhanced mobile broadband, Internet of Things and instant messaging applications.

Abstract
The present disclosure relates to transmitting data segments and includes methods and apparatus for performing, with a network entity, a random access channel (RACH) procedure for transmitting a first portion of a plurality of data segments from a user equipment (UE) to the network entity during a radio resource control (RRC) inactive state, wherein the RACH procedure includes receiving a physical downlink control channel (PDCCH) configuration from the network entity, the PDCCH configuration including an identified search space; and monitoring a PDCCH of PDCCH candidates addressed by a UE-specific network identifier in the identified search space for dynamic scheduling information for scheduling a second portion of the plurality of data segments.
