Abstract: This invention provides methods and systems for achieving high-specificity killing of targeted cells using Magneto-Electric Nano-Particles (MENPs) and functional or diagnostic imaging that detects changes at the cellular level. Embodiments comprise injecting into a patient's body manufactured MENPs that have a higher tendency to accumulate near or attach to targeted cells through one or more physical forces and/or biological mechanisms; and applying a magnetic field to the MENPs to generate an action that is sufficient to cause death of the targeted cells, and using an imaging apparatus to image or detect a specific property of the MENPs or changes in a property of the MENPs due to the coupling of the MENPs with their surrounding environment.

Abstract: This invention provides SRS transmission methods to meet the Massive MIMO systems requirements. These methods are described in two separate categories. Firstly, enhancements to multiplex more channels in the same resources for a given SRS transmission and to provide Massive MIMO throughput performance improvements. Secondly, scheduling enhancements to provide adaptive UE-specific scheduling based on channel conditions for each UE. These methods can be combined in different ways in each BS to optimize the channel estimation system capacity for a given level of system performance.
