Abstract
A first communication device determines a DMRS sequence based on a cover code in a set of cover codes; and thereafter determines a DMRS by mapping the DMRS sequence onto one or more PRBs. The cover code is dependent on a DMRS antenna port index, and cover codes in the set of cover codes are orthogonal to each other in each PRB, and wherein a maximum correlation power between two cover codes in the set of cover codes is larger than 0 in each half PRB. Finally, the first communication device transmits the DMRS via a DMRS antenna port having DMRS antenna port index to a second communication device which receive the DMRS and associated data signal. The second communication device demodulates the associated data signal based on the received DMRS and the DMRS sequence.
