Method and device in nodes used for wireless communication

Abstract

The present application provides a method and a device in a node for wireless communications. A node firstly receives a target information block, the target information block being generated in a protocol layer below an RRC layer, the target information block being used to determine a first time-frequency resource; and then performs a first random access procedure, the action of performing the first random access procedure comprising transmitting a first message; the first time-frequency resource is associated with one of a first identity and a second identity; the first message is used for random access; whether the first time-frequency resource is associated with the first identity is used to determine whether the first message is an MsgA or an Msg1. This application improves the criterion for determining 2-step random access in the case of Multi-TRP, thereby enhancing the efficiency of random access and optimizing the system performance.
