Abstract
A method for handling checksum error in uplink data compression (UDC) in a wireless communication system includes: detecting, by user equipment (UE), a checksum failure; automatically controlling, by the UE, generation of a number of compressed protocol data units (PDUs) available for transmission at a Packet Data Convergence Protocol (PDCP) based on a package formation rate (PFT); and transmitting, by the UE, a number of compressed PDUs.

A method for handling checksum error in an uplink data compression (UDC) in a wireless communication system, comprising:
- upon User Equipment (UE) detecting a checksum failure,
- determining, by the UE, a packet formation rate (PFT) from current channel conditions;
- adjusting, a number based on the PFT;
- controlling, by the UE, generation of the number of compressed protocol data units (PDUs) available for transmission at a Packet Data Convergence Protocol (PDCP);
- and
- transmitting, by the UE, the number of compressed PDUs to a base station.
A method for handling checksum error in an uplink data compression (UDC) in a wireless communication system, comprising:
- synchronizing, by a base station, a compression buffer between user equipment (UE) and a base station;
- compressing, by the base station, a number of data blocks at the UE and the base station based on the compression buffer;
- and
- controlling, by the base station, a decompression at the UE based on the compressed data block even if data protocol data units (PDUs) are processed out of sequence.
A method for handling checksum error in an uplink data compression (UDC) in a wireless communication system, comprising:
- receiving, by a base station, an FR bit set to 1 for a first protocol data unit (PDU) from user equipment (UE);
- and
- performing, by the base station, a buffer reset on a receiving UDC PDU with the FR bit set to 1.
