Abstract
Disclosed is a method and apparatus for managing a contention window based on detection of a transmission error, the method including: recognizing a transmission failure of data in the case of transmitting data using a contention-based wireless channel access method; verifying whether the transmission failure of data occurs due to a channel error or a collision by a contention between terminals; and determining a value of a contention window set in association with data transmission based on the verification result.

A method of managing a contention window based on detection of a transmission error, the method comprising:
- recognizing a transmission failure of data in the case of transmitting data using a contention-based wireless channel access method;
- verifying whether the transmission failure of data occurs due to a channel error or a collision by a contention between terminals;
- and
- determining a value of a contention window set in association with data transmission based on the verification result.
An apparatus for managing a contention window based on detection of a transmission error, the apparatus comprising:
- a recognizer to recognize a transmission failure of data in the case of transmitting data using a contention-based wireless channel access method;
- a verifier to verify whether the transmission failure of data occurs due to a channel error or a collision by a contention between terminals;
- and
- a determiner to determine a value of a contention window set in association with data transmission based on the verification result.
