Description

technical field

[0001] The present invention relates to wireless communication, and more particularly, to a method and apparatus for data transmission using an unlicensed frequency band in a wireless communication system. Background technique

[0002] With the explosive growth of mobile data traffic in recent years, service providers have utilized wireless local area networks (WLANs) to distribute data traffic. Because WLANs use unlicensed frequency bands, service providers can handle large data volumes without the expense of additional frequencies. However, there are problems in that an interference phenomenon becomes severe due to competitive WLAN installation among providers, when there are many users, quality of service (QoS) cannot be guaranteed, and mobility cannot be supported. As one of methods of compensating for this, Long Term Evolution (LTE) services in unlicensed frequency bands have emerged.
