| 20100124297 | Receiving a Pilot Design and Channel Estimation - Embodiments of the invention provide a receiver in an OFDM based communication system adapted to perform channel estimation using a received reference signal transmitted from at least one antenna, said reference signal being substantially located into two OFDM symbols of a transmission time interval comprising of more than two OFDM symbols. A method of generating pilot structure, the pilot structure provides information to an apparatus for channel estimation in the OFDM system with a transmission time interval of seven OFDM symbols. The pilot structure comprising pilot signals from at least one transmitting antenna located in various OFDM symbols of the transmission time interval. | 05-20-2010 |
| 20100272192 | OFDM-Lite Architecture for HomePlug - A device for communicating digital data over power lines includes a power line interface for transmitting data over at least one band of frequencies. An orthogonal frequency division multiplexing (OFDM) modulation unit generates OFDM symbols using a set of tones for the frequency band. A preamble generation unit generates preamble sequences for the frequency band by using the set of tones used by the OFDM modulation unit. The tones used by the preamble generation unit have a constant magnitude, and a set of phases obtained by quantizing to a small alphabet the phase of a set of tones obtained by taking an IFFT of a portion of a preamble used by a non-interoperable powerline access device. The device may transmit on two or more bands using a sampling frequency clock, wherein a lower band clock frequency is equal to or an integer divisor of a higher band clock frequency. | 10-28-2010 |

| 20090268831 | BACKWARD COMPATIBLE BANDWIDTH EXTENSION - A transmitter includes a bandwidth configuration unit configured to provide an increased system bandwidth corresponding to a bandwidth extension over multiple component carriers. Additionally, the transmitter also includes a transmit unit configured to employ the bandwidth extension. | 10-29-2009 |
| 20100056079 | RETRANSMISSION BETWEEN DCI FORMAT 1A AND FORMAT 2/2A - A transmitter is for use with a cellular communication network and includes a downlink control information (DCI) configuration unit that designates a DCI format for a downlink transmission selected from a first DCI format intended for a single transport block contiguous resource block transmission and a second DCI format intended for a dual transport block transmission available for spatial multiplexing. The transmitter also includes a retransmission coordination unit configured to facilitate a retransmission for the downlink transmission of a transport block corresponding to the first DCI format using the second DCI format or one of the dual transport blocks corresponding to the second DCI format using the first DCI format, based on a retransmission rule. | 03-04-2010 |
