20110268071 | MULTIPLE COMPONENT CARRIER OFDMA COMMUNICATION SYSTEM - A method of enhancing a downlink channel coding structure in an OFDMA (orthogonal frequency division multiple access) communication system is provided. The method includes: segmenting a concatenation of multiple transport blocks amongst multiple component carriers; and separately performing link adaptation for each component carrier according to channel conditions experienced by that component carrier. | 11-03-2011 |
20120002759 | DEMODULATION METHOD FOR MIMO SYSTEMS - A method for processing a plurality of data streams from a transmitter, includes: receiving symbols via the plurality of data streams; generating a channel matrix; sorting the channel matrix to provide a sorted channel matrix; performing QR decomposition on the sorted channel matrix and a column-row-swapped-sorted-channel matrix; performing QR equalization on a sorted received symbol vector and a swapped received symbol vector to provide a equalized-sorted vector and a equalized-swapped-sorted vector; processing first and second portions of the equalized-sorted vector and the equalized-swapped-sorted vector via a QR-MLD demodulation scheme to determine soft bits and soft symbols; and rearrange soft bits in the above steps to provide an output vector. | 01-05-2012 |
20120008522 | CHANNEL QUALITY INDICATOR METHOD - The disclosed a method will work with future versions of LTE-A, be backwards compatible, and alleviate interference to signals for basic system operation. The method includes generating one or more Reference Signals associated with the one or more Channel Quality Indicators, and includes mapping the one or more Channel Quality Indicator-Reference Signals to the last symbol of the second slot of the one or more subframes. | 01-12-2012 |
20120008576 | NON-COHERENT DETECTION METHOD OF THE NUMBER OF TRANSMIT ANTENNA PORTS FOR OFDMA - A method of non-coherent detection of the number of cell-specific transmit antenna ports for a communications device, includes the steps of, at the communications device: (a) generating a downlink reference signals (RS) sequence replica; (b) for a first possible transmit antenna port only, determining a downlink system bandwidth from non-coherent correlation of the generated downlink RS sequence replica and received RS samples; (c) at the determined downlink system, performing a correlation of the generated downlink RS sequence replica and received RS samples for each of a plurality of possible transmit antenna ports; and (d) determining the number of transmit antennas from a comparison of the correlation results in step (c). | 01-12-2012 |
20120120909 | METHOD FOR CONFIGURING PHICH CARRIER LINKAGE - There is provided a method of configuring the downlink component carrier between one or more linkage methods for PHICH reception on User Equipment (UE), which is configured for carrier aggregation, over a mobile communication network. This method includes (a) providing an indicator, and (b) determining whether the PHICH carrier linkage should be dynamic linkage or cell specific, based on the value of the indicator. | 05-17-2012 |
20120213186 | DOWNLINK CONTROL SIGNALLING FOR DOWNLINK MIMO - A method of downlink control signalling for downlink multiple input/multiple output (MIMO) operation between a Base Transceiver Station (BTS) and User Equipment (UE) includes the following steps. Maintaining one or more mapping tables at a network location accessible by the UE, the mapping tables including first UE signalling data. Transmitting a message index to the UE to enable relevant first UE signalling data to be read by the UE. Transmitting second UE signalling data to the UE. At the UE, using the first and second UE signalling data to derive UE control data. | 08-23-2012 |
