Title:
TERMINAL DEVICE, BASE STATION DEVICE, CONTROL METHOD, AND PROGRAM, FOR EXECUTING TWO-STEP RANDOM ACCESS PROCEDURE
Document Type and Number:
WIPO Patent Application WO/2021/059625
Kind Code:
A1
Abstract:
A terminal device that: sends a prescribed message to a base station device, on the basis of a two-step random access procedure; specifies a first wireless resource, if one signal is received in which upper layer control information for the terminal device and another terminal device is multiplexed and included; and uses the first wireless resource and sends a first response signal. The first wireless resource is for sending the first response signal indicating whether or not control information for a terminal device included in one signal sent in response to the prescribed message from the base station device has been successfully received. The first wireless resource is specified on the basis of at least either the one signal or a control signal used to send the one signal. The first wireless resource is different from a second wireless resource for sending a second response signal indicating whether or not another terminal device was successful in receiving control information, included in this one signal, for said other terminal device.
