拡張範囲のための狭帯域物理ランダムアクセスチャネル（ＮＰＲＡＣＨ）

Japanese Patent JP6938644

B2

An example method in a wireless device operating in a wireless network comprises generating a random access preamble signal and transmitting the random access preamble signal. The generated random access preamble signal comprises a random access symbol group that comprises a plurality of consecutive symbols, where each of the plurality of consecutive symbols being modulated on a corresponding subcarrier frequency and each of the plurality of consecutive symbols corresponding to a truncated sinusoid of 3.75/N kHz, with N>1.
