METHOD AND APPARATUS IN COMMUNICATION NODE USED IN WIRELESS COMMUNICATION

WIPO Patent Application WO/2024/017078

A1

Disclosed in the present application are a method and apparatus in a communication node used in wireless communication. The method comprises: a communication node determining K1, wherein K1 is a positive integer greater than 1; starting a first time window at a first moment; monitoring first signaling in the first time window, wherein the first signaling is used for scheduling a random access response; and sending a first preamble in at least a first time-frequency resource among K1 time-frequency resources, wherein any two time-frequency resources among the K1 time-frequency resources do not overlap in a time domain, the first time-frequency resource is the earliest time-frequency resource among the K1 time-frequency resources, the first moment is related to a cut-off moment of at least the first time-frequency resource, the first moment is not earlier than the cut-off moment of the first time-frequency resource and is earlier than a cut-off moment of a second time-frequency resource, the second time-frequency resource is the latest time-frequency resource among the K1 time-frequency resources, and an expiration moment of the first time window is later than the cut-off moment of the second time-frequency resource.
