Original Abstract Submitted

apparatuses and methods for uplink timing adjustment in a wireless communication system. a method for operating a user equipment (ue) includes receiving a first uplink (ul) timing advance (ta) command for a first link associated with a first physical cell identity (pci); receiving a second ul ta command for a second link associated with a second pci; and determining, based on the first and second ul ta commands, first and second ul timing adjustments for the first and second links associated with the first and second pcis, respectively. the method further includes transmitting a physical uplink control channel (pucch), a physical uplink shared channel (pusch), or a sounding reference signal (srs) associated with the first pci according to the first ul timing adjustment; and transmitting a pucch, a pusch, or a srs associated with the second pci according to the second ul timing adjustment. the second pci is different from a serving cell pci.
