Claim 0:
1. A method comprising:
receiving configuration information indicative of a measurement mode in relation to a neighbor cell,
deriving said measurement mode of said neighbor cell from said configuration information, and
measuring a reference signal of said neighbor cell based on said measurement mode, including determining downlink subframes for said measuring according to whether the measurement mode is related to an inband operation or whether the measurement mode is related to any of a guard-band operation mode of the neighbor cell and a stand-alone operation mode of the neighbor cell, and performing radio measurement of a reference signal in said subframes for said measuring;
wherein said configuration information is indicative of presence and/or absence of restriction of said downlink subframes;
wherein in relation to said measuring, without said measurement mode of said neighbor cell being derived, said method further comprises assuming transmission of said reference signal in downlink subframes 0 and 4 and, if a predetermined synchronization signal is not transmitted in downlink subframe 9, in said downlink subframe 9, and
wherein in case of indicated absence of restriction of said downlink subframes, without said measurement mode of said neighbor cell being derived, said method further comprises assuming transmission of said reference signal in downlink subframes 0, 1, 2, 3, 4, 6, 7, and 8, and, if said predetermined synchronization signal is not transmitted in said downlink subframe 9, in said downlink subframe 9.
