A method comprising: receiving time division duplex, TDD, configuration information (511-514, 611-615) by a user equipment, UE (501, 601), in a mobile communication network, wherein the TDD configuration information indicates the capability of TDD configuration change of a cell, referred to as adaptive TDD indication and/or provides an instantaneous TDD configuration pattern of the cell; performing downlink, DL, measurements over a serving cell or a neighboring cell, referred to as to-be-measured cell, by the UE (501, 601), after receiving the adaptive TDD indication and/or the instantaneous TDD configuration, characterized in that the performing step further comprises: if adaptive TDD is indicated in the received TDD configuration information, and it is determined that the to-be-measured cell does not have adaptive capability based on the received TDD configuration information, performing DL measurements according to a current operating TDD configuration, otherwise, if the UE knows that the to-be-measured cell has adaptive TDD capability but does not know the current operating TDD configuration, performing DL measurements on subframe #0 and subframe #5 only, and if an instantaneous TDD configuration pattern is provided in the received TDD configuration information, and it is determined that the UE knows the instantaneous TDD configuration pattern of the to-be-measured cell based on the received TDD configuration information, performing DL measurements according to the provided instantaneous TDD configuration pattern, otherwise, if the UE does not know the current operating TDD configuration but the UE knows that the to-be-measured cell has adaptive TDD capability, performing DL measurements on subframe #0 and subframe #5 only. receiving time division duplex, TDD, configuration information (511-514, 611-615) by a user equipment, UE (501, 601), in a mobile communication network, wherein the TDD configuration information indicates the capability of TDD configuration change of a cell, referred to as adaptive TDD indication and/or provides an instantaneous TDD configuration pattern of the cell; performing downlink, DL, measurements over a serving cell or a neighboring cell, referred to as to-be-measured cell, by the UE (501, 601), after receiving the adaptive TDD indication and/or the instantaneous TDD configuration, characterized in that the performing step further comprises: if adaptive TDD is indicated in the received TDD configuration information, and it is determined that the to-be-measured cell does not have adaptive capability based on the received TDD configuration information, performing DL measurements according to a current operating TDD configuration, otherwise, if the UE knows that the to-be-measured cell has adaptive TDD capability but does not know the current operating TDD configuration, performing DL measurements on subframe #0 and subframe #5 only, and if adaptive TDD is indicated in the received TDD configuration information, and it is determined that the to-be-measured cell does not have adaptive capability based on the received TDD configuration information, performing DL measurements according to a current operating TDD configuration, otherwise, if the UE knows that the to-be-measured cell has adaptive TDD capability but does not know the current operating TDD configuration, performing DL measurements on subframe #0 and subframe #5 only, and if an instantaneous TDD configuration pattern is provided in the received TDD configuration information, and it is determined that the UE knows the instantaneous TDD configuration pattern of the to-be-measured cell based on the received TDD configuration information, performing DL measurements according to the provided instantaneous TDD configuration pattern, otherwise, if the UE does not know the current operating TDD configuration but the UE knows that the to-be-measured cell has adaptive TDD capability, performing DL measurements on subframe #0 and subframe #5 only.
