Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method and an apparatus for quickly activating or deactivating a cell/cell group are provided. The method may include identifying whether an uplink (UL) data for a logical channel which belongs to a logical channel group (LCG) becomes available to a medium access control (MAC) entity associated with an activated cell group, identifying whether the UL data belongs to a first logical channel with higher priority than a priority of at least one logical channel containing available UL data which belongs to at least one LCG, in case that the UL data becomes available to the MAC entity associated with the activated cell group, and determining that a buffer state report (BSR) is triggered, in case that the UL data belongs to the first logical channel.
