摘要： The invention relates to methods and arrangements in a transmitting node (560) for enabling a receiving node (540) to perform measurements on interference caused by transmissions from at least one transmission point (510, 520, 530) controlled by the transmitting node (560) on receptions at the receiving node (540). The transmitting and receiving nodes (560, 540) are comprised in a wireless communications system (500, 600, 700). The transmitting node (560) determines an interference measurement resource, IMR, for the receiving node (540). The receiving node (540) is expected to measure interference on the IMR. The transmitting node (560) then transmits at least one interfering signal on the IMR. The at least one interfering signal is not expected to be decoded or coherently measured upon by any node (540, 550) served by the transmitting node (560).

摘要： As a basis for precoder quantization, a channel matrix representing multi-antenna channel characteristics between a transmitter and a receiver in the mobile communications network is estimated (S1 ). A channel-assisted vector selection procedure (S2-S4) for iteratively selecting precoding vectors for a precoding matrix is performed. Each of a number of iterations of the novel iterative vector selection procedure generally involves evaluation (S2) of the performance of each one of a set of candidate vectors included in a given vector codebook with respect to a predetermined performance measure that is dependent on the estimated channel matrix, and selection (S3) of one of the set of candidate vectors as a respective precoding vector for the precoding matrix based on the evaluated performance. Information representative of a set of select ed precoding vectors is then compiled (S5) to form a quantized representation of the precoding matrix for transmission to the transmitter side.
