Patent ID: 8537911

Claim:
A method for reference signal processing in a wireless communication user equipment, the method comprising: receiving a downlink transmission of configuration information, wherein the configuration information identifies a set of non-zero-power reference signals corresponding to a plurality of potential transmission points served by a same base station and at least one zero-power reference signal with zero transmission power, wherein a subset of the plurality of potential transmission points served by the same base station is selected and the at least one zero-power reference signal is configured as a zero-power reference signal with respect to the selected subset of the plurality of potential transmission points served by the same base station but not with respect to one or more other transmission points of the plurality of potential transmission points served by the same base station; performing a channel measurement based on one or more non-zero-power reference signals of the set of non-zero-power reference signals; and performing an interference measurement based on the at least one zero-power reference signal.
