Abstract: Systems, methods, apparatuses, and computer program products for handling NR slot aggregation in radio SL co-channel coexistence. A method may include determining that one or more slots of a first radio access technology overlaps a subframe of a second radio access technology. The method may also include detecting whether the second radio access technology is using the subframe of the second radio access technology. The method may further include determining by an outcome of at least one evaluated condition whether to transmit in the one or more overlapping slots or refrain to transmit in the one or more overlapping slots. The method may further include performing transmission with a same transmit power in all the slots that overlap the subframe of the second radio access technology.

Abstract: An arrangement for role management in relay communication is disclosed. In relay communication, one user equipment relays communication between a base station and at least one remote user equipment. Initially, the relay user equipment has a better signal to a base station. When the signal changes, a better signal channel may be achieved by switching roles between a relay user equipment and a remote user equipment. This includes detecting that a better signal exists and determining that a change would provide a better signal.

Abstract: Systems, methods, apparatuses, and computer program products for new radio (NR) sidelink relay of small data transmissions (SDT) are provided. One method may include determining whether conditions to use SDT via at least one relay user equipment are met. When it is determined that the conditions to use the SDT are met, the method may include transmitting a SDT relaying request comprising a SDT payload to the at least one relay user equipment. The method may also include receiving a SDT response, from the at least one relay user equipment, based on how the SDT relaying request is transmitted.
