Abstract: Systems, methods, apparatuses, and computer program products for device-to-device (D2D) assisted 5G timing synchronization by enabling or disabling time compensation are provided. One method may include determining to initiate a procedure to determine whether to enable or disable propagation delay (PD) compensation for acquiring 5G system (5GS) timing with a sidelink (SL) group of user equipment. When it is determined to initiate the procedure, the method may include transmitting propagation delay (PD) information of the user equipment as a sidelink (SL) groupcast message over a sidelink (SL) control channel to at least one of the group of user equipment, receiving at least one of acknowledgement or nonacknowledgement from one or more of the group of user equipment, and determining whether to enable or disable the propagation delay (PD) compensation based on the received acknowledgement or nonacknowledgement from the group of user equipment.

Abstract: An apparatus including at least one processor and at least one memory including computer program code. The at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus at least to receive, from a serving access node, a downlink radio resource control message including reference time information for a clock provided by the serving access node and traceability information for enabling traceability of the clock to a reference time standard. The traceability information includes at least information on a clock class indicative of a current status of the clock provided by the serving access node.

Abstract: Embodiments of the present disclosure relate to apparatuses, methods, and computer readable storage media for multi-consecutive slots transmission (Multi-consecutive slots transmission). An apparatus obtains at least one group of single-slot candidate resources available for a sidelink transmission. The apparatus determines, based on a first number of slots for multi-consecutive slots transmission, a first set of multi-consecutive slots transmission candidate resources from the at least one group of single-slot candidate resources, a multi-consecutive slots transmission candidate resource comprising the first number of consecutive slots. If the first set of multi-consecutive slots transmission candidate resources meets at least one multi-consecutive slots transmission candidate resource condition, the apparatus selects a target resource for transmission of the multi-consecutive slots transmission from the first set of multi-consecutive slots transmission candidate resources. Otherwise, the apparatus determines the target resource for transmission of the multi-consecutive slots transmission based on a multi-consecutive slots transmission criterion.

Abstract: Example embodiments of the present disclosure relate to a method, apparatus, and computer readable storage medium for resource exclusion. In a method, an apparatus determines at least one resource block (RB) set where a consistent listen before talking (LBT) failure is detected for the at least one RB set. Then, the apparatus determines the number of available candidate resources within a time window where the available candidate resources exclude candidate resources on the at least one RB set within the time window.

Abstract: Systems, methods, apparatuses, and computer program products for Rx-Tx RTT estimation are provided. One method may include transmitting, by a network element, the reference signal to another network element and recording a time stamp (t0) of a time of transmission of the reference signal, and receiving an estimated Rx-Tx measurement from said another network element and recording a time stamp (t3) of a time of receipt of the estimated Rx-Tx measurement. The method may also include calculating a Rx-Tx measurement at the network element based on a difference between the time stamp (t0) of the time of transmission of the reference signal and the time stamp (t3) of the receipt of the estimated Rx-Tx measurement, and determining a propagation delay based on a difference between the received estimated Rx-Tx measurement and the calculated Rx-Tx measurement.
