Abstract: A UE operates in a system where a source UE communicates using SL communications with a destination UE and detects a SL coverage issue with the sidelink communications between the source and destination UEs. The UE sends, to at least the destination UE, an announcement concerning at least one of the sidelink coverage issue or the UE being available as a relay UE candidate for an indirect path to the destination UE. The destination UE receives the announcement and communicates with the UE to set up and use the indirect path.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of Channel Occupancy Time (COT) for Sidelink (SL) communication in Unlicensed band (U-band). The method includes receiving, at a first device and from a second device, configuration information associated with a COT at least for a SL transmission of the first device on an unlicensed resource pool allocated for the first device, the configuration information at least indicating whether a listen before talk procedure is required to be performed at the first device within the COT before the SL transmission; and performing the SL transmission within the COT based on the configuration information. In this way, the COT sharing mechanism can be used for SL communications in U-band and therefore a sensing procedure for resource selection may not be impacted by the LBT procedure.

Abstract: Various example embodiments provide efficient burst transmission of duplicated data packets. A data burst comprising multiple data packets may be configured to be transmitted on a first transmission leg. The data burst may be further configured to be transmitted on a second transmission leg with a different order of data packets. A reception status of the data packets may be configured to be determined based on transmissions on the first and second transmission legs and non-acknowledged data packets may be retransmitted on the first transmission leg and/or the second transmission leg. Apparatuses, methods, and computer programs are disclosed.

Abstract: There are provided measures for enabling/realizing flexible and adaptive QoS monitoring for unicast/groupcast over sidelink communication, which may preferably be capable of enhancing support of unicast/groupcast services over sidelink communication. Such measures exemplarily comprise obtaining a request for QoS monitoring for unicast/groupcast over sidelink communication with a specified quality-of-service profile, which indicates at least one target QoS metric to be monitored, determining a QoS monitoring procedure, wherein a scheme for enforcing QoS monitoring over sidelink communication in collaboration with at least one unicast/groupcast receiving-side device is decided, and performing the QoS monitoring procedure, wherein QoS monitoring messages are exchanged with the at least one unicast/groupcast receiving-side device over the sidelink communication with the specified QoS profile in accordance with the decided scheme and the at least one target quality-of-service metric is derived based thereon.

Abstract: An apparatus in a network node has circuitry configured for causing a scheduling of an uplink transmission for a first user equipment and a downlink reception for a second user equipment on at least one resource, wherein the at least one resource is at least partially shared between the first user equipment and second user equipment. The apparatus has circuitry configured for providing an instruction, to the first user equipment, to transmit a first signal within the at least one resource. The apparatus also has circuitry configured for providing an instruction, to the second user equipment, to detect the first signal within the at least one resource. The apparatus having further circuitry configured for receiving information, from the second user equipment, wherein the information includes an indication of whether the second user equipment has detected the first signal.
