USER DEVICE AND BASE STATION

摘要

This disclosure pertains to a technology for reducing the flashlight effect in 3D MIMO. One mode of this invention pertains to a user device that has the following: a transmission/reception unit that receives an interfering-beam-candidate list containing directional beams transmitted by a serving base station and interfering-beam candidates transmitted by a neighboring base station; a measurement unit that measures the received quality levels of reference signals transmitted via the respective directional beams in the received interfering-beam-candidate list; and an interference-information generation unit that generates interference information on the basis of the measured received quality levels. The transmission/reception unit sends the generated interference information to the serving base station or the neighboring base station.
