Determining an Activation Order in Multiple Secondary Cell (SCell) Activation

An apparatus, comprising:

• at least one processor;
• and
• at least one non-transitory memory
• storing instructions that, when executed with the at least one processor, cause the apparatus at least to:
• receive a command to activate a plurality of secondary cells;
• determine an order for activating the plurality of secondary cells based on at least one of:
• whether the plurality of secondary cells includes an unknown cell,
• whether the plurality of secondary cells includes a known cell, or
• a number of unknown secondary cells to be activated in a band;
• and
• perform activation of the plurality of secondary cells based on the determined order.

An apparatus, comprising:

• at least one processor;
• and
• at least one non-transitory memory
• storing instructions that, when executed with the at least one processor, cause the apparatus at least to:
• receive a command to activate a plurality of secondary cells, wherein the plurality of secondary cells comprises a set of unknown secondary cells in a same frequency band;
• activate a first secondary cell of the set of unknown secondary cells;
• and
• based on the first secondary cell being activated, determine that one or more second secondary cells of the set of unknown secondary cells in the same frequency band are known.
