Abstract: Methods, systems, and devices for wireless communications are described. One method may inlcude a base station or other device estimating an intended coverage area of all possible communication devices that are to be serviced by the base station or other device. The base station or other device may dynamically optimize at least one transmission metric such as a codebook, in response to a change in the coverage area. Another method may include a base station estimating a dynamic coverage area of a set of all possible user equipments or devices to be serviced, and dynamically optimizing a codebook structure in response to a change in the coverage area. Another method may include the base station determining a use-case of the set of all possible user equipments to be serviced by the base station, and hard-coding a metric corresponding to the use case.

Abstract: A pair of stacked ground coplanar waveguides (GCPWs) is provided in two consecutive metal layers that are deposited on opposing surfaces of a dielectric layer. A first metal layer on a first side of the dielectric layer forms a first signal trace and an upper ground plane for a first GCPW in the pair. Similarly, a second metal layer on a second surface of the dielectric layer forms a second signal trace and an upper ground plane for a second GCPW in the pair.
