Abstract: A method and an apparatus for a second user equipment, that causes the apparatus to perform: determining whether a synchronization signal has been received during a first set of synchronization resources; and when it is determined the synchronization signal was received, determining that the apparatus is allowed to use communication resources during a second set of synchronization resources for a first sidelink communication; and when it is determined the synchronization was not received, abstaining from using the communication resources during the second set of synchronization resources for a first sidelink communication; and monitoring the second set of synchronization resources for a synchronization signal.

Abstract: Improved techniques of handover include the source gNB estimating the accuracy of the timing information that the UE may derive from its local clock during and shortly after the HO procedure and exchange this with the target gNB. Based on this estimate. the target gNB can determine when a timing information update is needed at the UE.

Abstract: There are provided measures for enabling/realizing support for idle period communication in semi-static channel access. Such measures exemplarily comprise that a user equipment device monitors for presence of a clearance indication provided by a base station device serving the user equipment device, which indicates clearance for communication by the user equipment device in at least one idle period of abase station device frame period, disables communication by the user equipment device in the at least one idle period of the base station device frame period when the monitoring yields absence of the clearance indication, and enables communication by the user equipment device in the at least one idle period of the base station device frame period when the monitoring yields presence of the clearance indication.

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: The specification describes apparatus comprising means for: estimating a propagation delay of transmissions between a base station and a mobile device based on data from at least one motion sensor that is local to the mobile device; determining updated timing information based on the estimated propagation delay; and updating an internal clock of the mobile device in accordance with the updated timing information.

Abstract: Embodiments of the present disclosure relate to at least one evaluation period, a detection period with allowed dropping rate or a measurement period determination. A terminal device measures a reference signal receives power (RSRP) associated with a physical sidelink broadcast channel (PSBCH) of a synchronization reference device, determines a number of consecutive periods associated with a listen before talk (LBT) failure in which a sidelink synchronization signal (SLSS) is unavailable from the synchronization reference device, and determines, based on the number of consecutive periods, at least one of an evaluation period, a detection period with allowed dropping rate or a measurement period for evaluating the RSRP, wherein the consecutive periods correspond to a plurality of consecutive sidelink synchronization signal block (S-SSB) periods or a plurality of consecutive discontinuous reception (DRX) cycles. Thus, wrong initiation of SLSS transmission event and wrong reselection of a SyncRef UE may be avoided.

Abstract: An apparatus including at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to perform: detecting absence of a hybrid automatic repeat request, HARQ, feedback for a transmission; determining that the transmission is associated with a sidelink unlicensed band; and based at least on the determining that the transmission is associated with the sidelink unlicensed band, using at least one interpretation rule in determining the detected absence of the HARQ feedback for the transmission either as a positive acknowledgement, ACK, for the transmission or as a negative acknowledgement, NACK, for the transmission.

Abstract: Various example embodiments provide efficient jitter control by means of a hybrid automatic repeat request (HARQ) process. Abase station may transmit to a UE a forwarding time parameter for data packet(s) associated with a HARQ process. The UE 110 may store the data packet(s) in a HARQ buffer and determine to hold the data packet(s) in the HARQ buffer until a delivery time determined based on the forwarding time parameter. Once the delivery time has been reached, the UE may forward the data packets to higher protocol layers. This enables efficient jitter control of a data packet flow. Apparatuses, methods, and computer programs are disclosed.
