Method and apparatus for transmitting data
First Claim
1. A method for transmitting data, comprising:
- performing, by a base station, a clear channel assessment (CCA) in a channel of an unlicensed band;
determining, by the base station, whether the channel is occupied in a first time period according to a CCA measurement value in the channel; and
determining, by the base station, a transmission power allowed during a second time period occupied by the channel according to a relationship between the CCA measurement value and a maximum transmission power,wherein the second time period is next to the first time period.

Abstract
Provided is a pre-5th-Generation (5G) or 5G communication system for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides a method for transmitting data, including: performing, by a Long-Term Evolution (LTE) equipment, Clear Channel Assessment (CCA) in one channel of a unlicensed band; and determining, by the LTE equipment, whether the channel can be occupied according to a CCA measurement value in the channel, and determining a data transmission parameter if it is determined that the channel can be occupied. The present disclosure also provides a corresponding apparatus. According to the method and apparatus provided by the present disclosure, the transmission power of the apparatus on the unlicensed band may be controlled, channel seizing opportunity is increased and effective coexistence is ensured.
