Summary: | A network controlling entity in a heterogeneous or local area network (such as a macro eNB) selects a set of network access nodes that share a common wake-up area code WUAC. The network controlling entity selects a transmission entity such as a motile terminal/UE and directs it to wirelessly transmit a signal on a given radio resource. The network controlling entity also informs each network access node within the set of the given radio resource on which they should listen for the signal. In various embodiments the network access nodes within the set can choose whether or not to listen for the signal and thus choose whether they will wakeup, or they can reply to the signal with a request for wakeup confirmation. In this manner WUAC-specific sets of small cells can be awakened only when needed for traffic offloading and thereby saving energy. |
