In one method, a user equipment (UE) is served by a cell supporting multiple numerologies. The UE is configured with a first numerology for data reception. The UE performs a measurement with a second numerology. ## Claims ### Claim 1 A method for performing a measurement, the method comprising: configuring, by a user equipment (UE), a first numerology for data reception, wherein the first numerology corresponds to a first subcarrier spacing; and performing, by the UE, a measurement with a second numerology, wherein the measurement is a radio link monitoring (RLM) measurement, a radio resource management (RRM) measurement, or an intra-frequency RRM measurement, and the second numerology corresponds to a second subcarrier spacing and the second numerology is a numerology used to acquire synchronization. ### Claim 2 (depends on 1) The method of claim 1, wherein the UE is served by a cell supporting different numerologies. ### Claim 3 (depends on 1) The method of claim 1, wherein the UE performs the measurement on a specific time frequency resource, wherein the specific time frequency resource is in a same transmission time interval as a synchronization signal. ### Claim 4 (depends on 1) The method of claim 1, wherein data reception is unavailable when the UE performs a measurement on the second numerology. ### Claim 5 (depends on 1) The method of claim 1, wherein the UE does not monitor a downlink control channel when the measurement is performed. ### Claim 6 (depends on 1) The method of claim 1, further comprising: configuring, by the UE, a measurement gap for the intra-frequency RRM measurement. ### Claim 7 A method for performing a measurement, the method comprising: performing, by the UE, a first type of measurement with a first numerology, wherein the first type of measurement is a radio link monitoring (RLM) measurement or a radio resource management (RRM) measurement, and the first numerology corresponds to a first subcarrier spacing; and performing, by the UE, a second type of measurement with a second numerology, wherein the second type of measurement is a Channel State Information (CSI) measurement, and the second numerology corresponds to a second subcarrier spacing and the second numerology is a numerology used to acquire synchronization. ### Claim 8 (depends on 7) The method of claim 7, wherein the first numerology is a predefined numerology, a fixed numerology, a default numerology, a numerology used to acquire synchronization, or a numerology the UE received synchronization signal. ### Claim 9 (depends on 7) The method of claim 7, wherein the first type of measurement and the second type of measurement are performed on different bandwidth portions. ### Claim 10 A method of performing a measurement, the method comprising: configuring, by the UE, a first numerology for data reception, wherein the first numerology corresponds to a first subcarrier spacing; and performing, by the UE, a channel state information (CSI) measurement on a reference signal with a fixed numerology, wherein the fixed numerology corresponds to a second subcarrier spacing and the fixed numerology is a numerology used to acquire synchronization. ### Claim 11 (depends on 10) The method of claim 10, wherein the data channel and the reference signal are transmitted on a same resource block. ### Claim 12 (depends on 10) The method of claim 10, wherein the data channel and the reference signal are transmitted on different symbols. ### Claim 13 (depends on 10) The method of claim 10, wherein the UE is configured with a first bandwidth for deriving resource allocation for the first numerology. ### Claim 14 (depends on 13) The method of claim 13, wherein the first bandwidth is a maximum bandwidth for the first numerology. ### Claim 15 (depends on 10) The method of claim 10, wherein the UE is configured with a second bandwidth for performing measurement. ### Claim 16 (depends on 10) The method of claim 10, wherein the UE is configured with a third bandwidth which is a system bandwidth of a cell serving the UE.
