1. A method comprising:determining amount information relating to an amount of reference information comprising demodulation reference symbols a user equipment is to provide, wherein said amount information identifies in which one slot or two slots and symbols of a subframe said reference information is to be provided, wherein the reference information in the one slot or two slots of the subframe is predetermined based on one of uplink grant messaging or a modulation and coding scheme/transmit block size;
causing said amount information to be provided to said user equipment;
in response to said amount information, receiving said reference information in said subframe from said user equipment, wherein based on the amount information the reference information is received in the predetermined one slot of the subframe or two slots of the subframe; and
using said reference information comprising said demodulation reference symbols from said user equipment to process data received over the subframe from said user equipment.
