    Abstract: A method and apparatus for generating channel quality information, such as may be used for transmit link adaptation, provide different operating modes, such as a first mode that may be used when propagation channel estimates are not reliable, and a second mode that may be used when the propagation channel estimates are reliable. In one or more embodiments, channel quality information is generated using receiver performance informatio that characterizes receiver performance in terms of a defined channel quality metric, e.g., supported data rates, for different values of receiver input signal quality over a range of propagation channel realizations. Channel quality information can be generated by selecting channel quality metrics according to receiver input signal quality and a desired probability of meeting a defined performance requirement over a range of propagation channel realizations, or by selecting channel quality metrics according to receiver input signal quality and particularized propagation channel realizations.

    Abstract: A wireless communication apparatus (106) is described, comprising:a processor (200); anda memory (114) with instructions stored therein, wherein the instructions are accessible and processable by the processor, wherein the processor is configured to:obtain an antenna subset list (116) that identifies one or more configurations of virtual antennas (110) associated with a scheduling unit (104) that is associated with at least one base station (102),wherein at least one identified configuration of virtual antennas includes a plurality of virtual antennas andwherein the antenna subset list indicates whether one virtual antenna or multiple virtual antennas of the at least one identified configuration can be selected for transmission;wherein the processor further employs an antenna subset mask to prevent one or more of the virtual antenna(s) in the antenna subset list from being selected for transmissions; andsend an antenna selection signal (118) that contains information requesting the scheduling unit to use the selected virtual antenna(s) for transmissions.

    Abstract: A method of supplying channel information in a wireless communication system comprises a mobile terminal normally providing a basic channel report to the wireless communication system; the mobile terminal receiving at least one common feedback criterion broadcast to a plurality of mobile terminals; the mobile terminal determining if the mobile terminal satisfies a condition based on the at least one common feedback criterion; and the mobile terminal selectively providing an enhanced channel report to the wireless communication system based on the determining. The basic channel report may comprise information related to a first set of channel parameters, and the enhanced channel report may provide greater detail on the first set of channel parameters and/or relate to a second set of channel parameters. A method of a base station adaptively controlling channel information reporting by broadcast transmitting at least one common feedback criterion is also presented.
