Embodiment Construction

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0023] (Configuration of wireless communication system)

[0024] figure 1 An example configuration of a wireless communication system according to this embodiment is shown. The wireless communication system according to this embodiment is, for example, a fifth generation (5G) mobile wireless communication system, and is configured to include a base station device (NR gNB) and a terminal device. A wireless connection is established between a base station device and a terminal device, and a wireless signal is transmitted or received. The base station device is connected to the core network, for example, by wire (connected via a line including a wireless section depending on the case), and is connected to other base station devices (not shown) via the core network. In addition, the core network is connected to an external network such as the Internet via a gateway, for ...

Abstract

When a radio link failure (RLF) occurs in a radio link that has been established in a first frequency band at a terminal device, a base station device notifies the terminal device of information related to a period for the terminal device to attempt to establish a radio link in the first frequency band. When an RLF occurs in a radio link in the first frequency band, the terminal device attempts tore-establish a radio link in the first frequency band, and when the period elapses with no success in re-establishing the radio link, the terminal device attempts to establish a radio link in a second frequency band which is lower than the first frequency band.

Description

technical field [0001] The present invention relates to a base station device, a terminal device, a control method and a program, and specifically relates to a connection control technology 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, forms a plurality of beams through beamforming, and establishes a connection with a terminal device using at least one of the beams. On the other hand, in the 5G system, it is possible to use radio waves of a higher frequency band than conventionally used. Here, the high frequency band, for example, can ensure a wide signal bandwidth and enable large-capacity communication. On the other hand, it is not easy to provide wide-area coverage. Therefore, it can be used to provide high-...
