Abstract: An SL UE that detects a resource conflict associated with a transmitting UE may be able to indicate this resource conflict by transmitting inter-UE coordination information over a PSFCH resource determined based on a group member ID of the transmitting UE. This may be different from transmitting HARQ feedback via a PSFCH resource determined based on a group member ID of the detecting UE.

Abstract: An apparatus, method and computer program is disclosed relating to positioning. For example, the apparatus may comprise means for operating the apparatus in a first operating state of a plurality of predetermined operating states as part of a positioning process involving communications with one or more remote nodes. The apparatus may also comprise means for identifying one or more trigger events and means for selecting a different one of the operating states, based at least on: the first operating state, and the presence or absence of one or more trigger events. The apparatus may transition from the first operating state to the selected different operating state, wherein the plurality of predetermined operating states may comprise a target state, an anchor state, a positioning reference unit (PRU) state, and a standby state.

Abstract: Systems, methods, apparatuses, and computer program products for sidelink group coordination for group-specific synchronization reference are provided. For example, a method can include determining, by a user equipment, whether a first condition is met for coordination on group synchronization reference for a group of user equipment. The method can also include determining, by the user equipment, whether a second condition is met to act as group synchronization reference user equipment for the group. The method can further include transmitting, by the user equipment, a group synchronization reference signal when determined to act as the group synchronization reference user equipment. The method can additionally include performing, by the user equipment, a reduced synchronization search when determined not to act as the group synchronization reference user equipment.

Abstract: According to an aspect, there is provided an apparatus configured to perform the following. The apparatus establishes itself as a timing source terminal device for sidelink communication and estimates a first time uncertainty caused by the apparatus for sidelink communication. Then, the apparatus causes transmission of information on at least one of the first time uncertainty and a combined time uncertainty to one or more target terminal devices. The combined time uncertainty corresponds to a combination of the first time uncertainty and a second time uncertainty. The second time uncertainty corresponds to a time uncertainty of reference time defined in reference time information.

Abstract: Apparatus and method to perform receiving from a network node of a first mobile network of more than one mobile network of a communication network, by a user equipment of the first mobile network, an indication (610) of an approaching coverage limit for a coverage area associated with a link between the first public land mobile network and the user equipment wherein the user equipment includes a multi subscriber identity module, and wherein a first subscriber identity module of the multi subscriber module is connected to a network node associated with the first mobile network; and based on the receiving, performing pro-active preparation for causing (620) a second subscriber identity module of the multi subscriber identity module of the user equipment to enable pro-active preparation of switching to a second mobile network of the more than one mobile network in response to an upcoming failure of the link between the user equipment and the first mobile network based on the approaching coverage limit of the coverage area. Further, there is determining, by a network node of a first mobile network of more than one mobile network of a communication network, an approaching coverage limit for a coverage area associated with a link between the first mobile network and a user equipment, wherein the user equipment includes a multi subscriber identity module and wherein a first subscriber identity module of the multi subscriber module is connected to a network node associated with the first public land mobile network; and based on determining, sending towards the user equipment information including an indication to perform pro-active preparation for causing a second subscriber identity module of the multi subscriber identity module of the user equipment to enable pro-active preparation for switching by the second subscriber identity module to a second mobile network of the more than one mobile network in response to an upcoming failure of the link between the user equipment and the first mobile network based on the approaching coverage limit of the coverage area.

Abstract: Example embodiments relate to an apparatus, method and computer program for timing compensation, for example timing compensation in relation to timing information provided by one or more positioning reference units (PRUs). An example method may involve providing data representing a timing error associated with a first position reference unit located at a first known position, with respect to a second position reference unit located at a second known position. The method may also comprise modifying timing information received from the first position reference unit, the modifying being based on at least the first timing error.
