Abstract: The present disclosure relates to an electronic device, a communication method and a storage medium in a wireless communication system. There is provided an electronic device for a network control device, comprising a processing circuitry configured to: interact with one or more neighbor cells of a user equipment (UE) to acquire support information on network slice type suitable for the UE fed back by each of the neighbor cells; based on the support information, evaluate a service capability metric for each of the neighbor cells with respect to said network slice type; and at least based on the service capability metric, determine a selection priority of each of the neighbor cells for the UE.

Abstract: An electronic device may have a display system. The display system may include a waveguide, an input coupler, and a surface relief grating (SRG) structure. The SRG structure may be formed from a high-index material that includes titanium dioxide nanoparticles. To increase the refractive index of the high-index material, the ratio of the size of the nanoparticle core to the size of the capping layer may be increased. The high-index material may also include nanoparticles of different sizes to increase the packing density of the nanoparticles. The SRG structure may be depth modulated in a lateral direction to maximize efficiency. The SRG structure may include slanted ridges covered by an encapsulant. The SRG structure may include a blazed grating with ridges that are covered by a coating and encapsulated by an encapsulant.
