Some aspects of this disclosure relate to apparatuses and methods for a user equipment (UE) to send a portion of a packet data unit (PDU) to a base station. A radio link control (RLC) layer of the UE generates a PDU and a truncation indicator, where the truncation indicator can indicate a set of truncation points of the PDU. A medium access control (MAC) layer determines whether an uplink transmission size based on an uplink grant is smaller than a first number of bytes included in the PDU. In response to a determination that the uplink transmission size is smaller than the first number of bytes, the MAC layer selects a truncation point from the set of truncation points indicated by the truncation indicator, and remove at least a portion of the PDU to generate a truncated PDU having a second number of bytes smaller than the uplink transmission size.
