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.

摘要： A method and unit for composing or decomposing a multimedia signal according to the Musical Instrument Digital Interface (MIDI) protocol. The signal carries events of a first type, which are arranged to carry instructions regarding which predefined patches to use for playback and which predefined notes to play, and events of a second type which carry additional content. The signal is parsed to identify events of the second type and to read the additional content. Coded samples of multimedia content are loaded at an address specified in the additional content. The coded samples are then decoded to provide the samples for playback of the multimedia content. In this manner, vocal song or vocals and other audio type signals are efficiently conveyed utilizing the widely used MIDI protocol.
