1. A cloud/centralized radio access network (C-RAN) in a wireless communication system, the C-RAN comprising:
a transceiver;
memory storing one or more computer programs; and
one or more processors communicatively coupled to the transceiver and the memory,
wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the C-RAN to:
determine, by the C-RAN connected directly to at least one secondary node (SN), the at least one SN to be activated from a plurality of secondary nodes (SNs) based on at least one of data requirement, a type of service, a load condition, or a signal condition associated with a user equipment (UE),
transmit, to the UE, a radio resource control (RRC) message comprising an activation field indicating whether each of the plurality of SNs is to be activated or deactivated, and
transmit, to the UE, a medium access control (MAC) control element (CE) to perform activating or deactivating of each of the plurality of SNs,
wherein each non-reserved bit of the MAC-CE to perform the activating or the deactivating of each of the plurality of SNs represents a SN the UE activates or deactivates,
wherein the activation field indicates activating the determined at least one SN and deactivating other SNs of the plurality of SNs except for the determined at least one SN, and
wherein the activation field corresponding to a first SN is set to 1 when the first SN is to be activated and the activation field corresponding to a second SN is set to 0 when the second SN is to be deactivated.
