Abstract
A user equipment (UE) can use carrier aggregation to connect to different cells provided by one or more base stations of a telecommunication network. One of the cells can be a primary cell (PCell), while another cell can be a secondary cell (SCell). The UE can send a power headroom report (PHR) that includes both a PCell power headroom indicating an available transmission power associated with the PCell, and an SCell power headroom indicating an available transmission power associated with the SCell. If the SCell power headroom is greater than the PCell power headroom, indicating that the UE has more available transmission power in association with the current SCell that may lead to improved metrics, a scheduler associated with the one or more base stations can send cell swap instructions to switch which cells the UE uses as the PCell and the SCell for carrier aggregation.
