摘要： Systems and methods for providing Channel State Information (CSI) feedback in a cellular communications network are disclosed. In some embodiments, a base station of a cellular communications network disables inter-subframe channel interpolation and/or filtering of CSI-RS estimates across subframes at the wireless device and receives one or more CSI reports from the wireless device that are generated by the wireless device with inter-subframe channel interpolation and/or filtering of CSI-RS estimates across subframes disabled in response to the base station disabling inter-subframe channel interpolation and/or filtering of CSI-RS estimates across subframes at the wireless device. In this manner, CSI feedback is improved particularly in embodiments in which the base station transmits a beamformed CSI-RS resource(s) and reuses the same CSI-RS resource(s) for different beams over time.

摘要： Techniques and apparatus for selectively switching among two or more possible reference signal densities are disclosed. An example method comprises obtaining (110) one or more reference signal conditions that governs the density of the reference signal format to be transmitted by a wireless communication device in conjunction with data transmissions, where the one or more reference signal conditions are defined in advance of any scheduling of those data transmissions. The example method further comprises evaluating (120) the one or more reference signal conditions and selecting (130) a density of a reference signal format, from two or more possible densities, based on the outcome of the evaluation. In embodiments where the node that carries out the evaluation is the transmitting node, the method further comprises transmitting (140) one or more reference signals in conjunction with one or more data transmissions, in accordance with the selected reference signal density.

A method for providing interference characterization data by a network node may include providing telecommunications services for a first wireless device associated with the network node. Characteristic data associated with at least one characteristic of an interfering signal associated with a second wireless device may be identified by the network node. The characteristic data associated with the interfering signal associated with the second wireless device may be transmitted to the first wireless device. The at least one characteristic may identify a resource allocation granularity configured from at least one physical resource block pair associated with the interfering signal.
