Abstract: Systems, methods, apparatuses, and computer program products for carrying information elements containing timing information to a remote user equipment via a relay UE. One method may include a relay user equipment receiving a system information block associated with reference time information from a network entity, and determining that a remote user equipment needs the reference time information. The method may further include transmitting the system information block to the remote user equipment according to at least one rule associated with the reference time information.

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: receiving a transmission via sidelink unlicensed band from a user equipment; determining a decoding result for the transmission; determining, based on at least one interpretation rule, an interpretation result of an absence of hybrid automatic repeat request, HARQ, feedback for the transmission; and determining, based on the decoding result and the interpretation result, whether to send the HARQ feedback for the transmission.

Abstract: Example embodiments of the present disclosure relate to feedback to scheduling release feedback. According to embodiments of the present disclosure, there is provided a solution for feedback to a scheduling release indication. The first device receives control information which comprises a scheduling release indication. The scheduling release indication is associated with a hybrid automatic repeat request (HARQ) process. The first device transmits a feedback to the release indication on an occasion allocated for the HARQ process. In this way, the second device does not need to transmit the scheduling release indication for several times, thereby saving resources. Further, overhead can be saved.

Abstract: An apparatus includes a memory and processing circuitry. The processing circuitry is configured to cause the apparatus to request synchronization reference source information from a user equipment, determine whether to conduct an offset compensation based on the synchronization reference source information, and, in response to a determination to conduct the offset compensation, obtain a first propagation delay associated with the apparatus, determine a reference time based on the first propagation delay, and forward the reference time to the user equipment.

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.
