Claim 6:
7. A base station comprising processing circuitry configured to receive at least two groups of reference signals, wherein
a first and a second group of the at least two groups each correspond to transmission on a plurality of antenna ports;
the first group corresponds to a smaller number of antenna ports than the second group; and
the maximum combined power on the antenna ports corresponding to the first and second group is substantially the same,, wherein, one or more of the antenna ports corresponding to the first group is formed according to at least one of a first and a second mechanism, wherein,
the first mechanism comprises simultaneously transmitting on multiple transmit chains to form the antenna port; and
the second mechanism comprises transmitting on an antenna port corresponding to the second group on a transmit chain of a plurality of transmit chains, wherein the transmit chain is capable of higher power transmission than other transmit chains in the plurality of transmit chains.
