摘要： Radio resource management measurements for new radio unlicensed are performed that are based on a measurement model where a missed received signal transmission opportunity indicator is provided to higher layers to adapt the measurement functions performed by the radio resource control when a missed received signal transmission opportunity is detected. Radio link monitoring for new radio unlicensed is performed based on in-sync or out-of-sync indications that are based on the estimated radio link quality in combination with missed radio link monitoring reference signal transmission opportunities.

摘要： Methods and apparatuses are described herein for Intra-UE Prioritization in uplink (UL) transmissions. In an example, an apparatus may receive first information indicating a first uplink grant associated with a first transmission and second information indicating a second uplink grant associated with a second transmission. The apparatus may determine, based on the first information and the second information, that the first transmission and the second transmission overlap at least partially in time. The apparatus may determine a first priority associated with the first transmission and a second priority associated with the second transmission. The apparatus may then cause, based at least in part on the first priority and the second priority, at least one of: prioritization of one transmission over another transmission, or preemption of the first transmission by the second transmission.

摘要： The present application is directed to an apparatus including a non-transitory memory including instructions stored thereon for monitoring synchronous signals and physical broadcast channels (SSBs) from a network node. The apparatus also includes a processor, operably coupled to the non-transitory memory, configured to execute a set of instructions. The instructions include configuring the apparatus for a STTC (SSB Transmission Timing Configuration). The STTC is a time interval with plural locations accommodating transmission of the SSBs. The instructions also include monitoring the STTC for the SSBs. The instructions further include determining a first one of the SSBs in a first slot of a subframe in a scheduled SSB transmission in the STTC has been transmitted at a first scheduled location, where the transmission of the first one of the SSBs is based upon confirmation of a successful Listen Before Talk (LBT) available channel prior to the scheduled SSB transmission in the STTC.

摘要： The present application may describe a method for obtaining channel access in a network. The method includes selecting, via a gNodeB, a spatial filter to perform listen before talk (LBT). The method includes detecting, via the gNodeB, a channel in an idle state. The method includes obtaining a directional channel occupancy time (COT). The method also includes transmitting a channel access indicator transmission (CAI-T) on a beam. The method further includes receiving a channel access indicator response (CAI-R). The method further includes sensing the channel is clear (e.g., via short channel sensing and the spatial filter). The method includes sending, via the channel, information to the node using one or more spatial filters of the second set of spatial filters. Other embodiments may include corresponding computer systems, apparatus, and computer programs recorded on one or more computer storage devices, each configured to perform the actions of the methods.

摘要： 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.

摘要： Methods, systems, and apparatus designed to support flexible carrier bandwidths in new radio. Multiple carrier bands may be combined into a single composite carrier depending on channel availability in the carrier bands. A composite carrier indicator (CCI) indicates to network devices, the available carrier bands within the channel occupancy time. In addition, bandwidth part inactivity time is suspended when channel access is not available.

摘要： 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.
