Abstract
According to some embodiments, a method for use in a network node of transmitting reference signals in a wireless network using a plurality of beams comprises obtaining a node identifier for the network node. The node identifier is unique for neighboring network nodes within a particular coverage area of the wireless network. The method further comprises obtaining a group of reference signal sequences. The group comprises a subset of a pool of possible reference signal sequences for use in the wireless network. Each reference signal sequence is associated with a beam reference identifier. The method further comprises selecting a reference signal sequence from the obtained group: scrambling a reference signal transmission pattern using the obtained node identifier and the selected reference signal sequence with associated beam reference identifier; and transmitting the scrambled reference signal transmission pattern to a user equipment on one of the beams among the plurality of beams.
