1. A method implemented by a base station for initializing pseudo-random sequence generators on which wireless devices base generation of uplink reference signals, comprising:

  • determining a first sequence from a first subset of possible initialization sequences for a pseudo-random sequence generator of a first wireless device;

    determining a second sequence from a second subset of possible initialization sequences for a pseudo-random sequence generator of a second wireless device, the range of the second subset spanning at least the range of the first subset;

    encoding the first sequence as a first set of two or more parameters;

    encoding the second sequence as a second set of one or more parameters, wherein the second set comprises fewer bits than the first set and includes at least one parameter not included in the first set; and

    initializing the sequence generators of the first and second devices with the first and second sequences by transmitting the first and second sets of parameters to the first and second devices.
