METHOD FOR SELECTING RACH PREAMBLE SEQUENCE FOR HIGH-SPEED MODE AND LOW- SPEED MODE

摘要

A method for selecting a RACH preamble sequence for a high-speed mode and a low-speed mode is disclosed. In the case of acquiring sequence -type information to be used by a specific UE contained in a high-mobility region, a signaling reanalysis method under a general circular shift condition is disclosed, and a method for acquiring sequence-type information via the signaling using the sequence set configured by a restricted circular shift condition is also disclosed. Finally, a method for constructing a sequence set is disclosed.
