摘要： Systems and techniques for carrier aggregated beamforming using elevation control. A base station determines a first elevation to be used for transmission to a user device using a first carrier, for example, based on information received from the user device. A second elevation, for transmission to the user device based on the second carrier, is determined based at least in part on the elevation information determined for the first carrier. The first and second carriers may be used by the same base station or by different base stations, and using elevation information determined for the first carrier to determine elevation information for the second carrier avoids computation and signaling needed for separate determination of the elevation information for the second carrier.

摘要： Various communication systems may benefit from channel state information feedback. For example, it may be helpful to improve channel state information feedback using time or frequency compression. According to certain embodiments a method may include determining at a user equipment a set of supported channels based on at least one of a first condition or a second condition. The first condition may include a selected number of channel support being greater than or equal to a configured number of channel support. The second condition may include a variance of a residual matrix being smaller than or equal to a threshold variance. The method may also include transmitting from the user equipment to a network entity a channel state information report comprising a channel support index set, based on the set of supported channels, after determining that at least one of the first condition or the second condition have been met.

摘要： A precoder is determined (e.g., at a base station) for a given layer and for a UE. The precoder includes a three-part product codebook structure. The determining uses CSI from the UE for the three-part product codebook structure, and the CSI corresponds to multiple antenna elements in at least a 2D array of cross-polarized antenna elements. The determined precoder is applied to information for the layer to be transmitted to the UE, and the precoded information for the layer is transmitted to the UE using the antenna elements in the at least 2D array of cross-polarized antenna elements. The UE can determine, using reference signal information transmitted using the antenna elements, the CSI corresponding to each part of a three-part product codebook structure for the layer, and report the determined CSI to the base station. Methods, apparatus, computer program products, and systems are disclosed.
