摘要: An uplink feedback channel reporting method is disclosed for using the primary and secondary fast feedback channels to efficiently report the channel quality, MIMO feedback, and CQI types of data from a mobile station to a base station. The reporting method reports regular information periodically and non-regular information on demand.

摘要: A resource metric quantization is described that has use for resources of wireless data communications system. In one example the quantization include measuring a signal parameter for a plurality of frequency partitions, setting a first resource metric for a first frequency partition equal to a first value, determining a second and a third resource metric for a second and third frequency partition, respectively, based on comparing the measured signal parameter for the second and third frequency partitions to the measured signal parameter for the first partition, encoding a second and a third resource metric, and transmitting the encoded resource metrics to a remote wireless station.

摘要: A feedback information separating section (105) takes out information indicative of an eigenvector, eigenvalues, and the number of effective eigenvalues, i.e. the number of eigen values larger than a specified threshold value included in the feedback information sent from the communication party. A section (151) for controlling the number of multiplex sequences determines the number of multiplex sequences (number of transmission streams) of transmission data based on the number of effective eigenvalues, and performs serial/parallel conversion of a sequence of transmission data into the number of sequences thus determined. Performance can be enhanced in a communication system employing MIMO.
