Abstract

Embodiments herein relate to a method in a user equipment (900) for applying power scaling to uplink transmissions in a multiple cell communications network which user equipment (900) is configured to transmit over a plurality of aggregated cells in uplink to a network node (800). The user equipment (900) receives from the network node (800) timing advance information for uplink one or more aggregated cells of the plurality of aggregated cells. The user equipment (900) applies a power scaling to uplink transmissions of at least one aggregated cell based on the received timing advance information The at least one aggregated cell is associated with the user equipment (900) and is a cell of the multiple cell communications network.
