Embodiment Construction

[0029] A wireless apparatus may be fixed or mobile and may be referred to as such as User Equipment (UE), Mobile Station (MS), Mobile Terminal (MT), User Terminal (UT), Subscriber Station (SS), Personal Digital Assistant (PDA) PDA), wireless modem, handheld device, etc. Alternatively, the wireless device may be a data communication enabled device such as a machine type communication (MTC) device.

[0030] A base station (BS) is typically a fixed station that communicates with wireless devices and may be called by additional terms such as evolved Node B (eNB), base transceiver system (BTS), access point, and so on.

[0031] To be described hereinafter, the present invention is applied based on the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) based on the 3GPP Technical Specification (TS). This is for exemplary purposes only, and the present invention is also applicable to various wireless communication systems.

[0032] A wireless device may be served b...

Abstract

Provided is a method and device for transmitting data in a wireless communication system. A wireless device establishes a connection in an unlicensed band, and transmits an extended signal for occupying a wireless channel during a signal-free interval in the unlicensed band.

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. [0003] LTE in Unlicensed Spectrum (LTE-U) or Licensed Assisted Acc...
