Title:
REFERENCE SIGNAL SEQUENCE DETERMINATION IN A WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/156734
Kind Code:
A1
Abstract:
Apparatuses, methods, and systems are disclosed for reference signal sequence determination. One apparatus includes a processor that determines an RS sequence for transmission. The RS sequence includes three symbols determined by the following equation: ř
u (n) = e
jϕ(n)πΙ
4 . The RS sequence includes: a first RS sequence, wherein ¥u (n) is the first RS sequence, n = 0 to 2, φ(0) = -3, φ( 1) = -3, and φ(2) = -1; or a second RS sequence, wherein ř (n) is the second RS sequence, n = 0 to 2, φ(0) = -3, φ( Υ) = 1, and φ(2) = 1. The apparatus also includes a transmitter that transmits the RS sequence on a time-frequency resource.
