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: 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: A method, apparatus, and computer program for determining, by transmitting user equipment, absence of a feedback message from receiving user equipment, which feedback message is related to a transmission of the transmitting user equipment over a sidelink to the receiving user equipment; determining by the transmitting user equipment whether the feedback message is absent from a sidelink physical feedback channel associated with a listen before talk type 2 channel access or with a shared channel occupancy time; and performing a first action that comprises incrementing a discontinuous reception counter associated with the sidelink in response to determining that the feedback message is absent from the sidelink physical feedback channel associated with the listen before talk type 2 channel access or with the shared channel occupancy time.

Abstract: Systems, methods, apparatuses, and computer program products for detecting consistent listen before talk failure cases and suitably recovering from such failure cases in the implementation of sidelink for unlicensed bands are provided. For example, a method can include monitoring a transmission resource pool in which the apparatus is operating. The transmission resource pool can include resource block sets, each of which can be monitored. The monitoring can be applied to resource block sets for which a prohibit timer is not running or is expired. The monitoring can be performed to detect listen before talk failures of the apparatus for each monitored resource block set of the plurality of resource block sets. The method can also include triggering or declaring a consistent listen before talk failure for the monitored resource block set when the count value of detected failures exceeds a threshold.

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.
