Abstract: Different sidelink resource configurations and allocation schemes may be controlled by an interface, such as the Uu interface. The radio resource control configurations may include dynamic assignment of broadcast sidelink transmission, unicast sidelink transmission, or group sidelink transmission. There may be radio resource control configured static resource allocation for broadcast sidelink transmission, unicast sidelink transmission, or group sidelink transmission.

Abstract: Sidelink communication operations may be enhanced through the use of communications requirement signaling, which may include, for example, indications of the type, size, quality of service requirements, pending buffer sizes, and the like, and through the evaluation of such signaled information to determine whether existing grants and logical channels may suffice for new sidelink traffic. Grants may be requested via sidelink scheduling requests and sidelink buffer status reporting, for example, which allow scheduling devices, such as base stations and scheduling user equipment apparatuses, early insight into needs of sidelink traffic for application with divergent QoS requirements.

Abstract: Sub-band (SB) indications and listen-before-talk (LBT) outcomes may be used to adjust communications between devices such as wireless terminals and base stations. For example, a wireless terminal may receive SB indications including SB configurations and/or LBT outcomes of a base station, and other information such as a remapped CORESET. Similarly, a terminal may determine that a physical resource block (PRB) is invalid based at least in part on whether the PRB overlaps with a guard band. The terminal may be arranged to adjust its searches and transmissions based on received SB indications, and to provide the base station with LBT outcomes of the terminal.

Abstract: The present application at least describes a frame structure in new radio. The frame structure includes a self-contained transmission time interval. The transmission time interval includes a control information region including plural beams. The interval also includes a downlink transmission channel region including plural beams. The frame structure is configured for downlink control information to be swept through the time interval. The frame structure is also configured for an uplink or downlink grant resource subsequently to be swept through the time interval. The present application is also directed to a method for configuring user equipment.

Abstract: Hybrid automatic repeat request (HARQ) processes may be transmitted via configured grants as well as scheduled grants. The configured grants may include time and frequency resources, and transmissions may occur across contiguous transmissions. HARQ process information, such as HARQ IDs and redundancy versions, may be communicated via a control channel, and the control channel may be multiplexed with the transmission resources of the configured grants. Retransmission timers may be used for HARQ processes conveyed via configured grants, and the transmitting apparatus may signal to a receiver when to send an acknowledgement. An acknowledgement may take the form of bitmaps for code block groups of a HARQ. A configured grant may be selected from among multiple configured grants based upon low latency, for example. A group of configured grants may be activated or deactivated via a single command.

Abstract: A first apparatus including a processor; and a memory storing computer-executable instructions that when executed by the processor cause the first apparatus to: receive, from a second apparatus, information including Discontinuous Reception (DRX) configurations, wherein one of the DRX configurations is a first active DRX configuration and other DRX configurations are candidate DRX configurations; perform Physical Downlink Control Channel (PDCCH) monitoring in accordance with the first active DRX configuration; monitor signaling from the second apparatus for an indication that is used for adapting the first active DRX configuration; receive from the second apparatus an indication for adapting the first active DRX configuration into a second active DRX configuration; based on the indication for adapting the first active DRX configuration into the second active DRX configuration, adapt the first active DRX configuration into the second active DRX configuration; and perform PDCCH monitoring in accordance with the second active DRX configuration.

Abstract: An electronic device that is configured to schedule transmission of data to at least one other electronic device via sidelink resources in a wireless communication network; identify that the scheduled transmission of the data is preempted by another transmission occurring within at least a part of the sidelink resources; and control transmission of the data to at least one other electronic device based on the identifying.

Abstract: Methods and apparatuses are described herein to address issues at the MAC layer resulting from potential Listen-Before-Talk (LBT) failures and delayed transmission. For example, a wireless transmit/receive unit (WTRU) may monitor a plurality of TX resource pools within a sidelink bandwidth part (BWP) for LBT events. The WTRU may cause, based on determining that an LBT failure has occurred, a corrective action associated with a sidelink MAC procedure. The WTRU may determine, based on the LBT failure, that a total number or consecutive number of detected LBT failures for one of the monitored TX resource pools exceeds a threshold, indicating a consistent LBT failure. The WTRU may, based on the consistent LBT failure, send an indication of the consistent LBT failure for the TX resource pool to peer WTRUs. and an indication of the consistent LBT failure for the TX resource pool to a serving cell.

Abstract: Multicast/Broadcast Service (MBS) for user equipments (UE) in Radio Resource Control (RRC) idle/inactive modes via signally of MBS frequency ranges and/or switching between frequency ranges as required. Bandwidth Part (BWP) operation for MBS in RRC_IDLE and RRC_INACTIVE states may be implemented using a dedicated MBS BWP or by sharing a frequency range with other operations. An MBS frequency range may be wider or narrower than an initial BWP used by a UE, for example. MBS frequency range configure may be achieved in a number of ways, such as via Control Resource Set (CORESET), search space, and/or PDCCH monitoring occasions pattern settings for MBS in RRC idle/inactive. Downlink scheduling without dynamic grant for MBS in RRC idle/inactive may include configured scheduling and/or semi-persistent scheduling. Downlink repetition for MBS in RRC idle/inactive may include PDSCH repetition and/or PDCCH repetition.
