Methods (500, 700) and nodes (110, 120)for transmission / reception of a data channel to a receiver (110), using at least one subframe (300), and at least one set of reference signals selected from a first or second candidate set of reference signals, each set of reference signals comprising a set of antenna ports. The method (500) comprises assigning (501) resource blocks (310) by means of control channel for the data channel in the subframe(300); associating (505) one set of reference signals, selected from the first or the second candidate set of reference signals with the assigned (501) resource blocks (310), utilising the set of antenna ports of the selected set of reference signals, based on a set of rules related to at least the assigned (501) resource blocks (310); and transmitting (506) the data channel on the assigned (501) resource blocks (310). |
