Title:
BASE STATION, TERMINAL DEVICE, COMMUNICATION METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/008212
Kind Code:
A1
Abstract:
In order to provide a configuration making it possible for a beam used for communication to be selected appropriately in an environment in which beam forming is performed by means of massive-MIMO, a base station is provided with: a communication unit which forms a plurality of beams to communicate with a terminal device; and a control unit which transmits to the terminal device first identification information of a group that contains a plurality of beams to be formed and that is to be used to communicate with the terminal device, from among the first identification information allocated to each of a plurality of groups.
