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.
