Control device, terminal device, control method, and program

Abstract

In a base station device including one or more first devices for executing control of a layer that includes a medium access control layer subordinate to a wireless resource control (RRC) layer, and asecond device connected to the one or more first devices, the second device executing control of a layer including an RRC layer super-ordinate to the layer on which the one or more first devices execute the control, a control device, which is any of the one or more first devices, notifies a terminal device about information on a beam to be measured by the terminal device, receives from the terminal device a measurement report pertaining to the beam to be measured, while a connection is established with the terminal device, selects, on the basis of the measurement report, a switching destination for the beam to which the terminal device is to connect; and notifies the terminal device about information about the beam. These processes are executed without interposition of the second device.

Description

technical field [0001] The present invention relates to a control device, a terminal device, a control method, and a program, and specifically relates to a handover technique in wireless communication. Background technique [0002] In the 3rd Generation Partnership Project, a new radio access technology of the fifth generation (hereinafter referred to as "5G") is being studied (see Non-Patent Document 1). In the 5G system, it is assumed that a base station device also called NR gNB is configured to include a plurality of devices called a Central Unit (CU) and a Distributed Unit (DU). In addition, DU is also called Transmission Receiver Point (TRP). Here, it is assumed that a DU performs processing of at least a layer including a physical (PHY) layer at a position lower than a radio resource control (RRC) layer, and a CU performs processing including an RRC layer at a position higher than a layer controlled by a DU. The inner layers are processed. In addition, it is assume...

Problems solved by technology

[0003] In the 5G system, it is possible to use radio waves in a higher frequency band than conventionally used radio waves, but such radio waves in a higher frequency band are strongly affected by obstructions, etc., so the radio wave state between the base station device and the terminal device will deteriorate rapidly
