Title:
TERMINAL DEVICE, BASE STATION DEVICE, AND METHOD
Document Type and Number:
WIPO Patent Application WO/2022/085640
Kind Code:
A1
Abstract:
This terminal device is provided with a receiving unit for receiving data from a base station device, and a processing unit, wherein the processing unit performs processing: to maintain a first state variable in a reception PDCP entity of the terminal device; and, in said maintaining, to set an initial value of a sequence number part of the first state variable to a first value on the basis that the data received from the base station device are MBS data, and to set the initial value of the first state variable to 0 on the basis that the data received from the base station device are at least not the MBS data.
