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: 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: Apparatus and method for communication are provided. One or more link identifiers used by a first terminal device are obtained. Information on communication of another terminal device with the first terminal device based on the obtained one or more link identifiers is obtained. Based on the obtained information, it is determined, that the first terminal device is active for communication and transmission to the first terminal device performed based on the determination.

Abstract: In accordance with example embodiments of the invention there is at least a method and apparatus to perform determining a first set of candidate single-slot resources for a physical sidelink shared channel transmission by a first user equipment; determining a second set of candidate multi-slot resources for the physical sidelink shared channel transmission by the first user equipment; and reporting at least one candidate single-slot resource from the first set and at least one candidate multi-slot resource from the second set to a higher layer for resource selection. Further, to perform determining a union set by forming a union of the first set and the second set; determining a subset of the union set by excluding a candidate resource at least based on whether the candidate resource overlaps with a resource reserved for transmission by a second user equipment; and reporting the determined subset to the higher layer for resource selection.

Abstract: A user equipment includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the user equipment to: select radio resources for a first sidelink transmission to a first user equipment based on sidelink control information from a second user equipment, the sidelink control information including at least beam information for a second sidelink transmission by the second user equipment; and perform the first sidelink transmission to the first user equipment on the selected radio resources.

Abstract: An apparatus, method and computer program is described comprising: determining a set of candidate radio resources for transmitting data from a first communication node of a non-terrestrial network to a second communication node of the non-terrestrial network over a direct radio link; identifying one or more of the candidate radio resources as conflicting radio resources that conflict with at least one scheduled radio transmission in the non-terrestrial network based, at least in part, on a propagation delay associated with the at least one scheduled radio transmission and/or a propagation delay associated with the radio transmission by the first communication node; generating a subset of candidate radio resources by excluding the identified one or more conflicting radio resources from the set of candidate radio resources; and selecting a radio resource from the subset of candidate radio resources for transmitting the data over the direct radio link.

Abstract: A method, apparatus, and computer readable storage medium provide sidelink beam alignment between devices. In the context of a method performed by a first user equipment (UE), the first UE causes transmission of a first plurality of reference signals to a second UE to facilitate selection of a first preferred beam among a plurality of beams of the second UE. The method also receives a second plurality of reference signals from the second UE using a plurality of beams of the first UE. The method further includes selecting a second preferred beam from the plurality of beams of the first UE based on the second plurality of reference signals.
