Abstract: Systems, methods, apparatuses, and computer program products for multi-link establishment for sidelink (SL) enhancement. A method may include transmitting, to a user equipment, a coordination request for communication over a plurality of beams. Beamformed reference signals may be exchanged with the user equipment identifying corresponding beams of the apparatus and the user equipment. Coordination information comprising at least one of preferred or non-preferred time-frequency-beam resources of the user equipment may be received from the user equipment including preferred or non-preferred radio resources of the user equipment and associated simultaneous links for their communication. At least one of preferred or non-preferred time-frequency-beam resources may be determined for their communication. At least two time-frequency-beam resources associated with different beams of the plurality of beams may be selected based on the at least one of determined preferred or non-preferred time-frequency-beam resources of the apparatus. Data in the selected at least two time-frequency-beam resources associated with different beams of the plurality of beams may be transmitted to the user equipment.

Abstract: In order to perform small data transmission during an RRC_INACTIVE mode, a UE may need to determine whether the stored timing advance (TA) is valid. A TA may be valid if its usage would result in an uplink transmission arriving at a TRP of a base station during a time period during which the base station expects to receive uplink transmission. A UE may determine that a TA is valid based on a received fraction of the length of a cyclic prefix and observed SSB time shift.

Abstract: Methods, apparatuses, and computer programs are provided for SRS for positioning resource overhead reduction in multi-RTT. A method for a UE includes receiving an initial configuration of a plurality of sounding reference signal for positioning resources; measuring a downlink positioning reference signal received from one or more cells; determining one or more transmission beams based on reception beams used for receipt of the downlink positioning reference signal from the one or more cells; wherein the determining of the one or more transmission beams comprises a reduction of at least one beam resource associated with a sounding reference signal for positioning; and transmitting an updated sounding reference signal for positioning configuration with information about the determined one or more transmission beams. Methods are also provided for a radio node and for an LMF.

Abstract: An arrangement for determining a location of a base station by user equipment uses measurements of reference signals of a base station from different user equipment positions. The measurement results are preprocessed and then provided to a machine learning entity. The machine learning entity estimates the location of the base station and provides the estimated location for use in other functionality of the user equipment.
