摘要:
The present invention discloses a node for transmission mode switching for downlink transmission in a downlink channel (100), comprising: a configuring unit (110) adapted to configure an initial transmission mode for the downlink transmission as a default transmission mode; a deriving unit (120) adapted to derive channel quality metric (CQM) of the downlink channel; a first determining unit (130) adapted to determine a first predefined threshold on the basis of link level simulation of a first transmission mode and a second transmission mode; and a first switching unit (140) adapted to switch the transmission mode from the initial transmission mode to the first transmission mode or the second transmission mode on the basis of the CQM and the first predefined threshold. The present invention provides a simple, direct and efficient approach for transmission mode switching for downlink transmission in a downlink channel on the basis of available feedback from UE (or other kinds of terminals if appropriate) and/or link adaptation decisions from eNB (or other kinds of base stations if appropriate), provides high peak rate while maintaining cell coverage, and provides a proprietary solution without any impact on protocol/standard or UE implementation.
