    摘要: An embodiment for a method for user equipment assisted three-dimensional beamforming is disclosed. The method may include the user equipment receiving a reference signal from an eNodeB comprising an antenna. The user equipment may then calculate an optimum antenna tilt for the antenna and transmit feedback to the base station. The feedback may include an indication of the optimum antenna tilt for the antenna. Additional signals may be received from the base station after a transmit angle of the antenna has been adjusted in response to the optimum antenna tilt.

    摘要: A receiver circuit receives a signal including a first reference signal from a first antenna port that is allocated to the UE. The receiver circuit includes a descrambling and despreading unit that despreads and descrambles the signal using a spreading code of the first antenna port and a scrambling sequence assigned to the UE to generate a first antenna port signal. The descrambling and despreading unit despreads and descrambles the signal using a spreading code of a second antenna port and the scrambling sequence assigned to the UE, wherein the second antenna port is unallocated to the UE to generate a second antenna port signal. A channel estimator generates a channel estimate of the first antenna port based on the first antenna port signal. An estimation unit estimates an interference and noise covariance measure based on the first antenna port signal, the channel estimate and the second antenna port signal.

    摘要: A device includes a first adjustment unit which is configured to adjust a power of a first carrier signal, and a second adjustment unit configured to adjust a power of a second carrier signal. The first adjustment unit is configured to adjust the first carrier signal power based on a maximum allowable imbalance between the first carrier signal power and the second carrier signal power. A method for controlling a transmit power in a user equipment of a radio communications system includes calculating in the user equipment first carrier signal power and a second carrier signal power. The method further includes adjusting in the user equipment the calculated transmit power for at least one out of the first carrier signal and the second carrier signal based on the maximum allowable power imbalance between the first carrier signal power and the second carrier signal power.

    摘要: A receiver is configured to receive a receive signal including a plurality of signal components, each signal component indicating a channel of an antenna port and an associated scrambling sequence, wherein a first one of the channels indicated by a first one of the signal components which is based on a first scrambling sequence is allocated to the receiver for data reception and a second one of the channels indicated by a second one of the signal components which is based on a second scrambling sequence different from the first scrambling sequence is interfering with the allocated channel. The receiver includes an interference reduction unit configured to combine an estimate of the first one of the signal components and an estimate of the second one of the signal components to provide an interference-reduced signal.
