Claim:
1. A method comprising: receiving time division duplex (TDD) configuration information by a user equipment (UE) in a mobile communication network, wherein the TDD configuration information comprises at least one of an adaptive TDD indication and an instantaneous TDD configuration; determining whether a to-be-measured cell applies adaptive TDD and performing downlink (DL) measurements over the to-be-measured cell by the UE according to a current TDD configuration of the to-be-measured cell if adaptive TDD is not configured; determining whether the UE knows the instantaneous TDD configuration of the to-be-measured cell; and performing DL measurements over the to-be-measured cell by the UE, wherein the UE only measures on common DL subframe(s) if adaptive TDD is applied and the UE does not know the instantaneous TDD configuration of the to-be-measured cell, wherein the UE is served by a serving cell different from the to-be-measured cell, and the TDD configuration information comprises the instantaneous TDD configuration of the to-be-measured cell, the method further comprising:
