1. A method implemented by a wireless device for initializing a pseudo-random sequence generator on which to base generation of an uplink reference signal, comprising:

  • selectively deriving one of the initialization sequences within a subset of possible initialization sequences for the sequence generator, according to one or more rules that define different initialization sequences in the subset as a function of a single parameter, wherein the single parameter is received from a base station, wherein said deriving comprises deriving the initialization sequence based on a defined one-to-one mapping of possible initialization sequences in the subset to possible values for the single parameter, wherein the range of the single parameter is smaller than the range of the subset, and wherein said deriving comprises deriving the initialization sequence cinit according to
