Abstract
[Problem] To propose a mechanism that makes it possible to achieve stability of a RACH procedure and reduction in latency of the RACH procedure at the same time. [Solution] A terminal device including a selector that selects, in a RACH procedure, whether to transmit a first uplink message or a second uplink message to a base station device, the first uplink message being an uplink message of a two-step RACH procedure, the second uplink message being an uplink message of a four-step RACH procedure.
Claims18
A terminal device comprising a selector that selects, in a RACH procedure, whether to transmit a first uplink message or a second uplink message to a base station device, the first uplink message being an uplink message of a two-step RACH procedure, the second uplink message being an uplink message of a four-step RACH procedure.
A base station device comprising
- a setting section that sets, in a terminal device, a first selection reference for the terminal device to select whether to transmit a first uplink message or a second uplink message in a RACH procedure, the first uplink message being an uplink message of a two-step RACH procedure, the second uplink message being an uplink message of a four-step RACH procedure.
A method executed by a processor, the method comprising
- selecting, in a RACH procedure, whether to transmit a first uplink message or a second uplink message to a base station device, the first uplink message being an uplink message of a two-step RACH procedure, the second uplink message being an uplink message of a four-step RACH procedure.
A method executed by a processor, the method comprising
- setting, in a terminal device, a first selection reference for the terminal device to select whether to transmit a first uplink message or a second uplink message in a RACH procedure, the first uplink message being an uplink message of a two-step RACH procedure, the second uplink message being an uplink message of a four-step RACH procedure.
A recording medium having a program recorded thereon, the program causing a computer to function as a selector that selects, in a RACH procedure, whether to transmit a first uplink message or a second uplink message to a base station device, the first uplink message being an uplink message of a two-step RACH procedure, the second uplink message being an uplink message of a four-step RACH procedure.
A recording medium having a program recorded thereon, the program causing a computer to function as a setting section that sets, in a terminal device, a first selection reference for the terminal device to select whether to transmit a first uplink message or a second uplink message in a RACH procedure, the first uplink message being an uplink message of a two-step RACH procedure, the second uplink message being an uplink message of a four-step RACH procedure.
