METHOD AND APPARATUS FOR CHANNEL ACCESS IN WIRELESS COMMUNICATION SYSTEM USING UNLICENSED SPECTRUM |
摘要 |
A method and an apparatus for channel access in a wireless communication system related to a 5th generation (5G) or pre-5G communication system for supporting a data rate higher than that of the 4G communication system such as long term evolution (LTE) are disclosed. The method includes receiving a feedback corresponding to data transmitted in a first subframe arriving after a first sensing period in an unlicensed band from at least one terminal, checking data reception state of the at least one terminal as one of acknowledgement (ACK), negative acknowledgement (NACK), and discontinuous transmission (DTX) based on the feedback, and determining a length of a second sensing period based on the data reception state of the at least one terminal. |

1. A method of a base station in a wireless communication system, the method comprising:
receiving a feedback corresponding to data transmitted in a first subframe arriving after a first sensing period in an unlicensed band from at least one terminal; checking data reception state of the at least one terminal as one of acknowledgement (ACK), negative acknowledgement (NACK), and discontinuous transmission (DTX) based on the feedback; and determining a length of a second sensing period based on the data reception state of the at least one terminal. |
