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: An intermediate apparatus and method for relaying data from a remote wireless device to a base station with reduced latency is discussed. The method includes the steps of receiving a transmission having control information and data. Determining from the control information that the data is to be forwarded to a wireless communication node and that a future data transmission comprising data to be forwarded is scheduled. Estimating from the control information an amount of the data in the future data transmission. Generating a resource request comprising the estimated amount of data in the future data transmission and transmitting, the resource request towards the wireless communication node.

Abstract: Systems, methods, apparatuses, and computer program products for remote user equipment direct to indirect path switching in sidelink relay are provided. For example, a method can include receiving, at a user equipment from a network element, a system information block message having an information element to configure monitoring of paging messages at a common paging occasion, which can be configured for user equipment that are in idle or inactive state and that are configured to act as a user-equipment-to-network relay user equipment. The method may also include monitoring a page at the common paging occasion based on the information element. The method may further include sending a random access preamble dedicated to the user equipment in response to the page. The method may additionally include performing a state transition to connected mode only after a response to the random access preamble is received.
