Abstract: A system and a method are disclosed. The method includes configuring the UE with a first UL subband configuration for communicating with an external device, wherein the first UL subband configuration designates a first set of one or more resource blocks (RBs) inside of a carrier for the UE to perform UL transmission, receiving a downlink (DL) signal indication, and overriding the first UL subband configuration with a second subband configuration based on the DL signal indication, wherein the second subband configuration designates a first communication configuration of the first set of one or more RBs inside of a subband and a second communication configuration of a second set of RBs outside of the subband.

Abstract: A method and an apparatus are provided in which a user equipment (UE) connected with a serving cell performs a random access channel (RACH) procedure for a non-serving cell. The UE acquires a time advance (TA) of the non-serving cell based on the RACH procedure. The UE performs an L1/L2-based handover from the serving cell to the non-serving cell with the acquired TA.
