Abstract
Disclosed is a method and a first transceiver of a wireless communication network, for handling reference signals. The method comprises receiving, from a second transceiver, at antenna elements of each of M antenna branches of the first transceiver and in time domain, an OFDM modulated wideband reference signal comprising an OFDM reference signal symbol mapped to every K subcarrier frequency of at least a subset of a carrier frequency bandwidth, and, at each of the M antenna branches, sampling the received wideband reference signal using N samples per OFDM symbol. The method further comprises, for each of the M antenna branches, accumulating the received, sampled wideband reference signal over at least two repetition blocks, each of length of N/K, to obtain a condensed signal with the length N/K samples and conveying the condensed signal over an interface to an aggregate unit.
