Abstract: An intrabody probe with a flexible portion is configured with one or more integrated EM loops of electrically-conductive elements wherein the EM loops when exposed to one or more external magnetic fields are configured to generate voltage signals that are indicative of position of the EM loops, such as when the EM loops are subjected to an external force that results in deformation. With multiple EM loops at different locations on the flexible portion of the probe, a collection of such voltage signals from each EM loop enables a system configured to receive and process the voltage signals to determine coordinates of the EM loops in a local coordinate system and track a shape in space representative of probe deformation in real time.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit first control information that is indicative of noise (e.g., phase noise, additive white gaussian noise (AWGN), or both) that impacts a spectral efficiency of a modulation and coding scheme (MCS). The MCS may be associated with a constellation of points that may be each representative of a respective candidate sequence of bit values encoded with a corresponding combination of signal amplitude and carrier phase. The UE may receive, based on transmitting the first control information, second control information that indicates a set of partitioning parameters indicative of a hierarchical partitioning of the constellation into a multiple subsets of points. As such, the UE may decode a message, modulated via the MCS, using the hierarchical partitioning indicated by the set of partitioning parameters.
