Abstract: In order to reduce power consumption of a wireless communication apparatus without unduly increasing latency a way of triggering activation of a transceiver on the apparatus is provided that uses different forms of wakeup signals and corresponding forms of wakeup signal detectors. This allows the transceiver to operate in a discontinuous receiving mode, with the different wakeup signal receivers detecting for wakeup signals at different times the times being indicated to the apparatus by a wakeup signal pattern sent by the network.

Abstract: Example embodiments may relate to systems, methods and/or computer programs relating to positioning, for example for terminating or adapting an established positioning session under certain conditions. For example, the method may involve monitoring, for a plurality of time instances during transmission over a wireless channel of a positioning signal from a first terminal to a second terminal as part of a positioning session, one or more features of the wireless channel. The method may also involve identifying based on a value of one, or a combination, of the monitored one or more features between a first time instance and a second time instance, a change indicative of transition of at least one of the first and second terminals from a first environment to a second environment. The method may also involve causing termination or adaptation of the active positioning session responsive to the identification.
