Abstract: 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.

Abstract: A hybrid combining method in a receiver is provided, and the method includes that wideband combining, e.g. using a maximum ratio combining (MRC) or an interference rejection combing (IRC) process, to combine signals distributed over a first plurality of subcarrier frequencies from antennas in the same polarization direction is performed, resulting in a combined signal for each polarization direction that is distributed over a smaller number of subcarrier frequencies, then a two-port narrowband IRC is done of these wideband combined signals for the two polarization directions, resulting in a diversity combined signal.

Abstract: The present invention discloses a user equipment (UE) (100), comprising: a first measuring unit (110) adapted to measure time alignment error (TAE) and/or frequency alignment error (FAE) for antenna ports belonging to transmission point devices in Coordinated Multipoint Transmission (CoMP), the TAE including internal TAE and/or external TAE; and a first feedback unit (120) adapted to feedback the measured internal TAE, and/or external TAE, and/or FAE to at least one of the transmission point devices. The present invention provides a simple, direct and efficient approach for measuring and feeding back the cell-specific internal TAE and/or the UE-specific external TAE/FAE by UE and compensating the TAE/FAE by the transmission point device in the CoMP transmission, so that the CoMP transmission can properly operate.

Abstract: The present invention relates to an apparatus (1) and method for estimating down link wide-band interference power and noise power in a mobile communications system. By using filters (6) that are matched to the multipath channels (3) of a number of base stations the received powers (I1, Ij, IJ,) from the base stations may be differentiated and calculated. The impulse responses of the multipath channels (3) are estimated and the filters are matched such that the impulse response of each filter is the complex conjugate of the time reverse of the estimated impulse response of one of the multipath channels. White noise is modeled as a signal that has passed a single-ray channel (4). The received noise power (IJ+1) is estimated by means of the output signals from the matched filters and the total received signal.
