Title: GROUPING OF SERVING CELLS WITH SHORTENED TRANSMISSION TIME INTERVALS
Abstract:
Aspects of the disclosure provide a method for grouping serving cells with shortened transmission time intervals in carrier aggregation. The method can include establishing a connection between user equipment and a base station on a primary cell in a wireless communication system, and transmitting a carrier aggregation configuration for configuring secondary cells for the user equipment from the base station to the user equipment, wherein serving cells with different downlink transmission time interval lengths are organized into different cell groups in the carrier aggregation configuration.
