Document Type and Number:
WIPO Patent Application WO/2021/064843
Kind Code:
A1
Abstract:
In the present invention, a terminal comprises: a receiving unit that receives information indicating a mapping relationship between transmission occasions of a random-access preamble relating to transmission of a message A in a two-stage random-access procedure and transmission occasions of a shared physical uplink channel; and a control unit that selects a transmission occasion of the shared physical uplink channel relating to transmission of a message A in the two-stage random-access procedure on the basis of the mapping relationship.
