    Abstract: The invention relates to a method and an arrangement 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 determines (910) an interference measurement resource, IMR, comprising a set of Time-Frequency Resource Elements, TFREs, upon which the transmitting node is expected to transmit interference. The transmitting node then transmits (930) at least one interfering signal on said IMR as said interference. The at least one interfering signal comprises at least one of a desired signal, that is expected to be decoded or coherently measured upon by the receiving node (540) or another node (550) served by said transmitting node (560), and another signal, that is not expected to be decoded or coherently measured upon by any node (540, 550) served by said transmitting node (560). The desired signal is transmitted in place of the another signal as said at least one interfering signal on one or more TFREs of the IMR when the at least one transmission point is to transmit the desired signal to the receiving node (540) or to the another node (550). The another signal is transmitted on TFREs of said IMR where no desired signal is transmitted and the another signal is muted on TFRE's of said IMR where the desired signal is transmitted.

    Abstract: The invention relates to methods and arrangements for rank adaptation for transmissions over a multipie-input-muttipie-output, M1MO, channel in a wireless communications system. A receiving node (270) performs (310) measurements on reference signals received from a sending node (200), The receiving node performs (330a( 330b) a first feedback computation for a first rank and at least one second feedback computation for at yeast one second rank based on the measurements. The first feedback computation includes applying a first relation between assumed transmitted energy for data and transmitted energy for the reference signals that is specific to the first rank. A second relation between assumed transmitted energy for data and transmitted energy for the reference signals is specific to the at least one second rank. The receiving node selects (340) one rank based on the feedback computations and indicates (350) the selected rank in a feedback report to the sending node.

    Abstract: According to one or more aspects, the teachings herein improve user equipment (UE) Channel State Information (CSI) feedback, by letting the precoder part of a CSI feedback report comprise factorized precoder feedback. In one or more such embodiments, the factorized precoder feedback corresponds to at least two precoder matrices, including a recommended "conversion" precoder matrix and a recommended "tuning" precoder matrix. The recommended conversion precoder matrix restricts the number of channel dimensions considered by the recommended tuning precoder matrix and, in turn, the recommended tuning precoder matrix matches the recommended precoder matrix to an effective channel that is defined in part by said recommended conversion precoder matrix.
