Abstract

There are provided measures for a pathloss-based access node wake-up control, more specifically a pathloss-based access node wake-up control in a heterogeneous network environment. Such measures exemplarily include a retrieval of an average handover pathloss level between an access node and a neighboring access node, an estimation of an uplink sounding pathloss level between the access node and a terminal, said terminal being connectable to the access node and the neighboring access node, a comparison of the estimated uplink sounding pathloss level and the retrieved average handover pathloss level, and an enabling of a switch-on of the access node from an inactive state in which a transmitter is switched off to an active state in which the transmitter is switched on, when the estimated uplink sounding pathloss level is smaller than the retrieved average handover.
