Title:
データ送信方法および通信デバイス
Document Type and Number:
Japanese Patent JP6490188
Kind Code:
B2
Abstract:
The present invention discloses a data transmission method and a communications device, so as to resolve an existing problem that use of an unlicensed spectrum is interfered with between LTE devices when a padding is sent. The method includes: performing, by a communications device, CCA on an unlicensed spectrum; and when determining that the unlicensed spectrum is in an idle state, sending, by the communications device on a preset band resource in the unlicensed spectrum, a signal indicating that the communications device uses the unlicensed spectrum, where the preset band resource is a partial band resource in the unlicensed spectrum. Because the communications device sends, only on the preset band resource in the unlicensed spectrum, the signal indicating that the communications device uses the unlicensed spectrum, and the preset band resource is a partial band resource in the unlicensed spectrum, data transmission of another communications device is not affected, and mutual interference between communications devices when the unlicensed spectrum is used is eliminated.
