==Truncation of a Packet Data Unit (PDU) for Uplink Transmissions - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17484358 titled 'Truncation of a Packet Data Unit (PDU) for Uplink Transmissions

==Simplified Explanation==

The abstract describes a patent application related to apparatuses and methods for a user equipment (UE) to send a portion of a packet data unit (PDU) to a base station.

* The radio link control (RLC) layer of the UE generates a PDU and a truncation indicator, which indicates where the PDU can be truncated.
* The medium access control (MAC) layer determines if the uplink transmission size, based on an uplink grant, is smaller than the first number of bytes in the PDU.
* If the uplink transmission size is smaller, the MAC layer selects a truncation point from the set of truncation points indicated by the truncation indicator.
* The MAC layer removes at least a portion of the PDU to generate a truncated PDU with a second number of bytes smaller than the uplink transmission size.

== Potential Applications ==
* This technology can be applied in wireless communication systems where UE devices need to send data to a base station.
* It can be used in various applications such as mobile networks, IoT devices, and other wireless communication systems.

== Problems Solved ==
* The technology solves the problem of efficiently transmitting data from a UE to a base station when the uplink transmission size is smaller than the size of the generated PDU.
* By allowing the truncation of the PDU, the technology ensures that the transmitted data fits within the available uplink transmission size.

== Benefits ==
* The technology enables efficient use of limited uplink transmission resources by truncating the PDU to fit within the available size.
* It improves the reliability and performance of wireless communication systems by ensuring that data can be transmitted even when the uplink transmission size is smaller than the PDU size.


==Original Abstract Submitted==

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.
