Title:
DISTRIBUTED UNIT, CENTRAL UNIT, AND METHODS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/090201
Kind Code:
A1
Abstract:
A central unit (1) that is a base station transmits, to a distributed unit (2) that is a base station, a message for requesting addition of a secondary cell of carrier aggregation. This message includes a first information element indicating whether the secondary cell initially should be activated or dormant. This can contribute, for example, to improvement for enabling direct setting of a secondary cell state in an architecture in which base stations are separated into a central unit and a distributed unit.
