Abstract: Dynamic and partial sharing of the channel measurement downlink reference signal resources are provided. An apparatus performs determining information relating to an actual number of ports configured for a user equipment for channel measurements and determining a pool of channel state information reference signal resources for the user equipment. The pool of channel state information reference signal resources is provided in a radio resource control configuration and includes an excess number of ports compared to the actual number of ports. The apparatus also transmits to the user equipment via at least one of a medium access control control element or downlink control information, configured user equipment specific mapping for the pool of channel state information reference signal resources.

Abstract: A method for implementing co-polarized feedback for frequency domain compression is disclosed. The method includes feeding back compressed channel state information, wherein at least one layer is restricted to be transmitted on one polarization and the feedback for the at least one layer only involves the channel state information on the one polarization.

Abstract: A method and apparatus may include measuring a space frequency downlink channel matrix. The space frequency downlink channel matrix reflects a channel response observed by the apparatus. The apparatus receives transmissions from an array of antennas of a network node. The method can also include determining a spatial channel vector. The method can also include determining scalar phase terms. The method can also include determining a Signal-to-Interference-Plus-Noise-Ratio scalar factor of the channel response observed by the apparatus. The method can also include transmitting an encoded form of the spatial channel vector. The method can also include transmitting an encoded form of the Signal-to-Interference-Plus-Noise-Ratio scalar factor. The method can also include transmitting an encoded form of the scalar phase terms.

Abstract: Systems, methods, apparatuses, and computer program products for non-linear precoding in radio access networks are provided. One method may include, when it is determined that a user equipment is capable of being non-linearly precoded, determining one of two non-linear precoding modes and indicating the determined non-linear precoding mode to the user equipment. One of the two non-linear precoding modes is configured to use explicit beamformed channel state information, and the other one of the two non-linear precoding modes is configured to use explicit full downlink channel state information.

Abstract: Various communication system may benefit from the appropriate selection of communication parameters. For example, certain wireless communication systems may benefit from the user of a low-overhead high-rank codebook. A method can include determining a first partition of a precoding matrix with a higher resolution and a second partition of the precoding matrix with a lower resolution. The method can also include feeding back the first partition and the second partition.
