  ,, where Nsymbslot is a quantity of symbols in a slot, ns,fμ is an index of a subframe or a slot, l is an index of a symbol, nSCID is a scrambling factor NIDg(λ, nSCID) is a sequence scrambling identity, λ is a parameter with a value of one of 0, 1, or 2, and g(λ, nSCID) is a function that satisfies:

g(λ,nSCID)=nSCID, when λ=0 or 2; or

g(λ,nSCID)=1−nSCID, when λ=1

generate the sequence based on the initialization factor;
generate a first reference signal based on the sequence; and
cause a transmitter to send the first reference signal.
