Title: METHODS AND APPARATUSES FOR SIGNALING AND DETERMINING REFERENCE SIGNAL OFFSETS
Abstract:
Methods and apparatuses disclosed herein enable the use of Demodulation Reference Signal, DMRS, sequences that are numbered relative to an overall system bandwidth (30), while simultaneously enabling wireless communication devices (12) to determine the DRMS sequence elements mapped to their scheduled bandwidths (36) within the system bandwidth (30). Advantageously, the wireless communication devices (12) need not know the system bandwidth (30), or even be aware of where their scheduled bandwidths (36) reside within the system bandwidth (30).
