Abstract: Systems, methods, apparatuses, and computer program products for reducing user equipment (UE) transmit (Tx) timing error group (TEG) reporting overhead. A method may include receiving, from a first network element, an indication that a sounding reference signal for positioning will be used for uplink and downlink plus uplink positioning. Configuration for the sounding reference signal resource for positioning may be received from a second network element. The sounding reference signal resource for positioning may be associated with a user equipment transmit timing error group. The first network element or the second network element may be informed that a user equipment will report the user equipment transmit timing error group association to the first network element or to the second network element. The user equipment transmit timing error group association may be reported to the first network element or to the second network element.

Abstract: Systems, methods, apparatuses, and computer program products for dynamic gap symbol in sidelink positioning reference signal (SL PRS) resource configuration. A method may include receiving, from a user equipment, a sidelink control information indicating whether a gap symbol exists for a sidelink positioning reference signal transmission. The method may also include determining a time domain allocation of the sidelink positioning reference signal. The method may further include receiving, from the user equipment, a sidelink positioning reference signal with or without the gap symbol. In addition, the method may include performing a positioning computation based on the sidelink positioning reference signal received from the user equipment.

Abstract: Systems, methods, apparatuses, and computer program products for connected mode mobility management for group of users in a vehicle and served by the non-terrestrial network deployments are provided. For example, a method can include detecting, by a user equipment, a cell-edge condition while the user equipment is being served through non-terrestrial radio access. The user equipment can also initiate prioritized transmission conditioned on the detected cell-edge condition and can transmit uplink data transmission using the prioritized transmission before leaving coverage provided by the non-terrestrial radio access.

Abstract: Systems, apparatuses and/or method for positioning are provided. One method may include receiving, by a user device, a first request. The first request may indicate to the user device to report positioning reference signal (PRS) reference signal received power (RSRP) for a set of PRS resources corresponding to a previous report which indicated5 PRS reference signal received path power (RSRPP) of the user device previously obtained at a first time stamp. The method may also include transmitting, by the user device, a second report based on at least one status of the user device.
