1. A method of operation at a wireless communication device configured for operation in a wireless communication network, the method comprising:
determining, based on information received from a network node in the network, a sequence offset for a demodulation reference signal (DMRS) sequence;
determining, based on the sequence offset, which reference signal sequence elements of the DMRS sequence map to a scheduled bandwidth of the wireless communication device; and
transmitting one or more of the determined DMRS sequence elements of the DMRS sequence;
wherein the scheduled bandwidth is a portion of a larger, system bandwidth associated with the network, and where the DMRS sequence elements map to the system bandwidth according to a mapping between respective DMRS sequence elements and respective subcarriers constituting the system bandwidth.
