Claim Text:
1. A method for wireless communication at a user equipment, comprising: generating a demodulation reference signal (RS) sequence having a length equal to a total size of assigned non-contiguous clusters of subcarriers of a plurality of resource blocks of a slot of a subframe; clustering a first set of contiguous subcarriers to generate a first cluster of subcarriers; clustering a second set of contiguous subcarriers to generate a second cluster of subcarriers, at least one subcarrier being defined between the first set of contiguous subcarriers and the second set of contiguous subcarriers, the assigned non-contiguous clusters comprising at least the first cluster and the second cluster, a number of contiguous subcarriers of each cluster being equal to or greater than a number of symbols of each segment; partitioning the demodulation RS sequence into segments, one segment for each cluster of the assigned non-contiguous clusters; and transmitting a demodulation RS associated with the demodulation RS sequence segments on the assigned non-contiguous clusters.
