It would be to provide a method which 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.

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.

Multiple component carrier OFDMA communication system

This invention relates with a method for detecting a downlink control structure for carrier aggregation in communication network in which data transmission is scheduled by a physical downlink control channel (PDCCH). An UE receives higher layer signaling enabling carrier aggregation for the UE. The UE reads the PDCCHs of component carriers (CCs), wherein the downlink control information (DCI) in the PDCCHs of each CC is read according to one of a plurality of predefined formats derived from the higher layer signaling.

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.

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.

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).
