Example embodiments of the present disclosure relate to transmission of control information associated with sidelink positioning reference signal. In an example method, a first terminal device in a radio access network comprises at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the first terminal device to: transmit, to a second terminal device in the radio access network, control information associated with a sidelink (SL) positioning reference signal (PRS) during a SL positioning session for positioning of the second terminal device, using a resource for the control information in a Physical Sidelink Feedback Channel (PSFCH) symbol or in at least one symbol dedicated for the control information. In this way, the first terminal device can efficiently transmit control information to the second terminal device with backward compatibility.

Transmission of control information associated with sidelink positioning reference signal

There is provided a method for a user equipment. UE, of a wireless communication network, the method comprising: obtaining a first measurement data associated with a determined position of the UE and second measurement data, the first and second measurement data obtained by performing measurements by the UE; obtaining a difference value indicative of a difference between at least one measurement value of the first measurement data and at least one measurement value of the second measurement data; comparing the difference value with at least one repositioning threshold value provided by the wireless communication network to the UE; and if the difference value exceeds the at least one repositioning threshold value, triggering a transmission of a repositioning request to a network node of the wireless communication network.

Enhancing positioning efficiency

Disclosed is a method comprising receiving (), from at least one terminal device () by a wake-up receiver (WURx) of an apparatus (), at least one enhanced wake-up signal (), and deciding (), by the wake-up receiver (WURx), based on the at least one enhanced wake-up signal (), whether or not to wake-up the apparatus () from a network energy saving mode.

Network energy saving

Various example embodiments relate to positioning of a target node. A positioning report may comprise positioning assistance measurements from the target node and at least one anchor node, wherein the positioning assistance measurements are associated with angular differences between a pair of uplink and/or downlink transmission and/or reception beam directions. Apparatuses, methods, and computer pro-grams are disclosed.

Spatial domain measurements for beam based positioning

Devices, methods and computer program products for beam ranking for positioning purposes are disclosed. A network node device transmits to a client device a beam ranking indication comprising beam specific first reference data and beam ranking criteria for positioning for downlink transmission beams between the network node device and the client device. In response to a received downlink transmission beam selection indication indicating a downlink transmission beam selected by the client device based on the transmitted beam ranking indication, the network node device transmits second reference data to the client device with at least one downlink transmission beam according to the received downlink transmission beam selection indication.
