The base station also includes processing circuitry configured to map primary synchronization signals (PSS) and secondary synchronization signals (SSS) onto each of a carrier of a first carrier type and a carrier of a second carrier type. The PSS and SSS on the second carrier type are mapped onto different time locations than in the first carrier type. In addition, the PSS/SSS are mapped onto consecutive resource elements (REs) on each of the carrier of the first type and the carrier of the second type. | 2013-09-05 |
20130229954 | FREQUENCY SYNTHESIZER ARCHITECTURE IN A TIME-DIVISION DUPLEX MODE FOR A WIRELESS DEVICE - A dual frequency synthesizer architecture for a wireless device operating in a time division duplex (TDD) mode is disclosed. In an exemplary design, the wireless device includes first and second frequency synthesizers. The first frequency synthesizer generates a first oscillator signal used to generate a first/receive local oscillator (LO) signal at an LO frequency for the receiver. The second frequency synthesizer generates a second oscillator signal used to generate a second/transmit LO signal at the same LO frequency for the transmitter. The two frequency synthesizers generate their oscillator signals to obtain receive and transmit LO signals at the same LO frequency when the wireless device operates in the TDD mode. | 2013-09-05 |
20130229955 | FREQUENCY SCAN METHOD FOR DETERMINING THE SYSTEM CENTER FREQUENCY FOR LTE TDD - A method, an apparatus, and a computer program product for wireless communication are provided in which a set of time intervals is obtained from a received radio frequency signal. A power profile is determined for a frequency spectrum segment in each time interval. A first list is used to identify frequency spectrum segments that exhibit a power or energy profile over a range of frequencies associated with a downlink channel bandwidth, and a second list is used to identify frequency spectrum segments that have a total or average energy greater than a threshold energy relative to a noise floor. An absolute radio frequency channel number (ARFCN) of a wireless communication system is determined based on the time intervals identified in the first and second lists. | 2013-09-05 |
