Abstract
According to certain embodiments, a method in a radio node includes obtaining a parameter associated with a reference signal type and using the parameter associated with the reference signal type to calculate an initial value, Cinit, for a reference signal. A reference signal sequence is generated using Cinit, and the reference signal is demodulated using the reference signal sequence.
Claims26
A method in a radio node, the method comprising:
- for calculating an initialization value, Cinit, for a reference signal, obtaining a parameter associated with a reference signal type;
- calculating Cinit using an equation and using at least the parameter associated with the reference signal type, wherein the Cinit is a function of the reference signal type, such that with a different reference signal type, a different Cinit is calculated using the equation;
- generating a reference signal sequence using Cinit;
- and
- demodulating the reference signal using the reference signal sequence.
