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: r u (n)=e j [phi](n)Pi|4 . The RS sequence includes: a first RS sequence, wherein y u (n) is the first RS sequence, n = 0 to 2, [phi](0) = -3, [phi](1) = -3, and [phi](2) = -1; or a second RS sequence, wherein r(n) is the second RS sequence, n = 0 to 2, [phi] (0) = -3, [phi] (r) = 1, and [phi](2) = 1. The apparatus also includes a transmitter that transmits the RS sequence on a time-frequency resource.
