摘要： The present invention relates to a solution for efficient handling of radio resources in communication devices in a wireless communication network. In the solution a subset of available antennas to be used is chosen using a method for determining a singular valued metric from a sub matrix related to a full channel matrix. Sub-channel matrices are chosen by deducing the metric and comparing to other sub-matrices. Preferably the best sub-channel matrix is used to determine a suitable full channel matrix to use in communication and this full channel matrix is communicated to each involved communication device.
