Abstract: A user equipment (UE) and a flexible protocol data unit (PDU) packaging method thereof are provided. The user equipment performs a flexible PDU packaging procedure in a radio link control (RLC) layer when receiving configuration information that configures a 7-bit length indicator (LI) size and a flexible PDU size from a base station. The user equipment uses an exactly-filled LI to indicate the end of a service data unit (SDU) occurring at the end of the previous one PDU and an accumulated SDU size of the previous one PDU exceeds 123 octets. In addition, the user equipment utilizes a special value of a header extension (HE) field or an alternative E-bit of the header to indicate that the PDU includes only one SDU and the SDU is a complete SDU.
