Abstract  Abstract

Method and device for wireless communication are described. The first method includes transmitting a first orthogonal frequency division multiple access (OFDMA) communication signals and at the same time the first OFDMA communication signals the second OFDMA communication signal is not sent to the wireless node in the licensed frequency spectrum to the wireless node in the licensed frequency spectrum. the second method comprises in the spectrum of permission received from the wireless node a first orthogonal frequency division multiple access (OFDMA) communication signals and receiving the communication signal with the first OFDMA OFDMA communication signal from the wireless node receives the second not in the spectrum of the license. the third method comprises generating a cellular downlink is not used in the spectrum of a permission of the periodic gating interval and the at least one boundary frame structure of the periodic interval of the periodic with at least one boundary of the anchor component carrier and associated cellular downlink synchronization.

Methods and apparatuses are described for wireless communications. A first method includes transmitting a first Orthogonal Frequency-Division Multiple Access (OFDMA) communications signal to a wireless node in a licensed spectrum and transmitting concurrently with the transmission of the first OFDMA communications signal a second OFDMA communications signal to the wireless node in an unlicensed spectrum. A second method includes receiving a first Orthogonal Frequency-Division Multiple Access (OFDMA) communications signal from a wireless node in a licensed spectrum and receiving concurrently with the reception of the first OFDMA communications signal a second OFDMA communication signal from the wireless node in an unlicensed spectrum. A third method includes generating a periodic gating interval for a cellular downlink in an unlicensed spectrum and synchronizing at least one boundary of the periodic gating interval with at least one boundary of a periodic frame structure associated with a primary component carrier of the cellular downlink.
