Claim 0:
1. A method, comprising:
receiving, by a user equipment (UE) on a first carrier, a synchronization signal (SS) and a physical broadcast channel (PBCH);
acquiring, by the UE, a time/frequency synchronization based on the SS and the PBCH;
performing, by the UE, a radio resource management (RRM) measurement on the first carrier based on the SS and the PBCH;
performing, by the UE, a random access channel (RACH) procedure with the first carrier in accordance with the RRM measurement;
applying, by the UE, the time/frequency synchronization to a second carrier different from the first carrier;
receiving, by the UE, a first reference signal (RS) on the second carrier, the first RS being configured for the UE; and
performing, by the UE, a second RRM measurement on the second carrier based on the first RS while the UE is connected to the first carrier and the second carrier.
