Abstract: Systems, methods, and apparatuses for sidelink collision avoidance based on sensing, such as PSFCH sensing, are provided. One method may include sensing, by a first UE, a first sidelink feedback transmission from a second UE in a first PSFCH resource, and determining, based on the first PSFCH resource, a first radio resource in which the second UE received a first data transmission from a third UE. The method may also include sensing a second sidelink feedback transmission from the second UE in a second PSFCH resource, determining, based on the second PSFCH resource, a second radio resource in which the second UE received a second data transmission from the third UE, and determining, based on at least one of the determined first radio resource or second radio resource, a third radio resource in which the second UE is expected to receive a third data transmission from the third UE.

Abstract: The present disclosure relates to reference signal transmission alignment. In particular, a target device determines whether a reference signal transmission alignment is needed among a set of anchor devices. If the reference signal transmission alignment is needed, an anchor device receives a request for the reference signal transmission alignment. The anchor device determines a transmission time window based on the request and transmits a reference signal as per the transmission time window. In this way, it can mitigate an impact of synchronization timing reference change at the target device in measurement. Consequently, the solution allows for high accuracy measurements and hence enables high accuracy sidelink positioning.

Abstract: Inter-alia, a method e.g. performed by an anchor user device is disclosed comprising:



receiving a first target sidelink positioning reference signal;
transmitting a first anchor sidelink positioning reference signal;
performing a receiver-transmitter time difference measurement based on the first target sidelink positioning reference signal and the first anchor sidelink positioning reference signal;
transmitting an indication of a suggestion to switch from a first sidelink round-trip time positioning method to a second round-trip time positioning method based on the receiver-transmitter time difference measurement.




Further, inter-alia a method performed by a target user device is disclosed as well as respective anchor and target user devices.
