Abstract
The present disclosure generally aims to prevent failure of decoding data in a wireless communication system. A method for operating a receiving end comprises the steps of: receiving a packet from a transmitting end; decoding the received packet using encoded parameters; detecting failure to release compression of a header in the decoded packet; and adjusting the value of the encoded parameters according to the detection of failure to release compression.
Claims18
A method for operating a reception end in a wireless communication system, the method comprising:
- receiving a first packet from a transmission end;
- deciphering the first packet by using an enciphering parameter;
- detecting a failure in decompression of a header of the deciphered first packet;
- in response to the failure in decompression of the header of the deciphered first packet being detected, determining whether a static field value of the first packet is valid;
- in case that the static field value is valid, transmitting a NACK message;
- and
- receiving a second packet in which a static field and a first part of dynamic field are compressed and a second part of dynamic field is uncompressed in response to the transmitting of the NACK message.
An apparatus for a reception end in a wireless communication system, the apparatus comprising:
- a transceiver;
- and
- at least one processor coupled with the transceiver and configured to:
- receive a first packet from a transmission end,
- decipher the first packet by using an enciphering parameter,
- detect a failure in decompression of a header of the deciphered first packet,
- in response to the failure in decompression of the header of the deciphered first packet being detected, determine whether a static field value of the first packet is valid,
- in case that the static field value is valid, transmit a NACK message, and
- receive a second packet in which a static field and a first part of dynamic field are compressed and a second part of dynamic field is uncompressed in response to the transmitting of the NACK message.
