Abstract: Examples of the disclosure relate to wake-up signals for devices with no main radio or for which a main radio is turned off. An apparatus can be arranged in a low power state and can be arranged to receive a wake-up signal via a low power receiver when in the low power state. The wake-up signal comprises information identifying an apparatus or type of apparatus, and instructions to perform one or more actions in response to the wake-up signal. The apparatus can determine if the wake-up signal is intended for the apparatus based on the information identifying an apparatus or type of apparatus in the wake-up signal. The apparatus can perform the one or more actions indicated in the wake-up signal based on the determination.

Abstract: A solution for sidelink-assisted positioning of a terminal device. In an embodiment, a procedure in the terminal device includes transmitting, over a sidelink, a message including at least one information element requesting at least one anchor terminal device to report its location to the terminal device; receiving, over the sidelink from the at least one anchor terminal device, a location report including at least one information element indicating a location of the reporting anchor terminal device and an accuracy metric indicating accuracy of the location; determining a location estimate of the terminal device based on the accuracy metric and the location of the at least one anchor terminal device.

Abstract: Aspects and embodiments relate generally to mechanisms to support power saving in a wireless communication network and more particularly to supporting discontinuous reception of a wake-up signal receiver at an apparatus comprising a wake-up signal receiver and a main radio receiver. One aspect provides an apparatus, comprising: a main radio receiver; a wake-up signal receiver; and a timer. The wake-up signal receiver comprises: circuitry configured to receive at least a portion of a broadcast message; circuitry configured to evaluate the received portion of the broadcast message to determine a time marker; and circuitry configured to provide the time marker to the timer. The apparatus may comprise a UE and may therefore be configured to align internal time keeping with the time keeping of a network, thus allowing discontinuous reception and associated energy savings, without transmission of additional specific synchronisation messaging by a network.
