1. A method for wireless communications for a base station, comprising:

  • determining a first delay spread for a first antenna port of a channel;

    assigning a first pilot signal for the first antenna port to a first cyclic shift of a symbol of a subframe based at least in part on the first delay spread;

    determining a second delay spread for a second antenna port of the channel, wherein the first antenna port and the second antenna port are different;

    assigning a second pilot signal for the second antenna port to a second cyclic shift of the symbol of the subframe based at least in part on one or both of the first delay spread or the second delay spread;

    determining remaining available cyclic shifts for the symbol of the subframe; and

    multiplexing data on the remaining available cyclic shifts for the symbol, wherein the data is transmitted by one or both of the first antenna port or the second antenna port.
