Techniques for managing wireless communications over multiple carriers

An apparatus for managing ultra low latency (ULL) communications over a plurality of component carriers (CC), comprising:

• at least one processor;
• and
• a memory communicatively coupled with the at least one processor;
• wherein the at least one processor is configured to:
• receive a configuration for aggregating a set of CCs, wherein the set of CCs includes at least a primary cell and a secondary cell;
• communicate, based on the received configuration, with at least the primary cell for legacy communications, wherein the legacy communications are based on a first transmission time interval (TTI) having a first duration;
• communicate, based on the received configuration, with at least one of the primary cell or the secondary cell for ULL communications, wherein the ULL communications are based on a second TTI having a second duration that is less than the first duration;
• receive a deactivation command for ULL communications with at least one of the primary cell or the secondary cell;
• and
• receive an activation command for activating legacy communications with the at least one of the primary cell or the secondary cell, along with deactivating ULL communications with the at least one of the primary cell or the secondary cell.
