US 2019/0159250 A1 · TRANSCEIVING APPARATUS AND SPECTRUM ACCESS CONTROLLING METHOD THEREOF

Abstract

A transceiving apparatus and a spectrum access controlling method thereof are provided. The transceiving apparatus may utilize an unlicensed spectrum. In the method, feedback information related to accessing the unlicensed spectrum is received. An energy detection threshold is modified according to the feedback information. Whether to access the unlicensed spectrum is determined according to the modified energy detection threshold. If a signal strength detected on the unlicensed spectrum is greater than the energy detection threshold, an access to the unlicensed spectrum is disabled. If the signal strength detected on the unlicensed spectrum is not greater than the energy detection threshold, the access to the unlicensed spectrum is performed. Accordingly, the chance that a data transmission collision occurs is decreased, and a utilization rate of the unlicensed spectrum is improved.
