Title:
可変サブフレーム長をサポートするためのＯＦＤＭシンボルのプリフィックス処理
Document Type and Number:
Japanese Patent JP6781773
Kind Code:
B2
Abstract:
The present disclosure relates to a first radio node (300) configured for orthogonal frequency division multiplexing (OFDM), comprising a receiver (310), a transmitter (320), a processor (330) and a memory (340) storing instructions executable by the processor (330) for causing the transmitter (320) in a first mode of operation with a first subcarrier spacing f1: to transmit a sequence of prefixed OFDM symbols, and in a second mode of operation with a second subcarrier spacing f2: to transmit a sequence of prefixed OFDM symbols, wherein the sequence of transmitted OFDM symbols is aligned with a predefined repeating radio frame, which is common to both the first and second modes of operation, or with an integer multiple of the predefined repeating radio frame; and the first and second subcarrier spacings are related by an integer factor, f1/f2 = p or f1/f2 = 1/p, with p 1 integer.
