摘要： Embodiments of systems and methods for flexible Channel State Information (CSI) feedback in a cellular communications network are disclosed. In some embodiments, a base station configures a wireless device with a set of CSI-RS resources, dynamically configures a CSI-RS resource from the set of CSI-RS resources for measurement, and receives a CSI report from the wireless device determined from the CSI-RS resource dynamically configured for measurement. In this manner, the base station is enabled to dynamically configure and re-configure the CSI-RS resource(s) for measurement by the wireless device, which in turn provides flexible CSI feedback that is particularly well-suited for embodiments in which the base station transmits beamformed CSI-RS.

摘要： Embodiments herein relate to a method in a radio base station (12) for transforming a data transmission signal in a radio communications network. The radio base station (12) is connected to an active antenna array of a first number of active transmitting antennas, which each active transmitting antenna comprises sub elements. The radio base station (12) comprises a precoder codebook comprising precoders for transmitting signals in a diversified manner for a second number of antenna ports. The radio base station serves a user equipment in the radio communications network. The radio base station (12) precodes the data transmission signal with a precoder selected from the precoder codebook. The radio base station (12) furthermore transforms, linearly, the precoded data transmission signal by neutralizing a direction of the precoded data transmission signal and then directing the precoded data transmission signal vertically. The precoded data transmission signal is thereby enabled to be vertically adjusted towards the user equipment (10).

摘要： A method in a user equipment for estimating a channel upon receiving an enhanced control channel, eCCH, from a network node in a telecommunications system. The eCCH is distributed over multiple resource block pairs, wherein each of the multiple resource block pairs comprises a number of resources. Each resource is associated with a respective antenna port. The user equipment identifies an antenna port being associated with more than one resource. The more than one resource is present in different resource block pairs of the multiple resource block pairs over which the eCCH is distributed. The identifying is based on how the eCCH is mapped to the multiple resource block pairs. Also, the user equipment estimates the downlink channel for the eCCH based on the identified antenna port in the more than one resource in the multiple resource block pairs. A user equipment, a method in network node and a network node are also provided.
