Multi-link establishment for sidelink enhancement

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.
