Title:
任意接続チャネル信号を送信する方法とユーザ機器、及び任意接続チャネル信号を受信する方法及び基地局
Document Type and Number:
Japanese Patent JP6867480
Kind Code:
B2
Abstract:
User equipment in a wireless communication system receives RACH configuration information including preamble format information indicating a first format and transmits an RACH preamble in the first format. The RACH preamble in the first format includes a cyclic prefix (CP) part and a sequence part in a time domain. The RACH preamble in the first format satisfies the following: the CP length of the RACH preamble in the first format is N times the CP length NCP of an OFDM symbol, wherein N represents the number of OFDM symbols used for the transmission of the RACH preamble and is greater than 1.
