Abstract: Cross scheduling of a component earner for vehicle sidelink communications may be achieved by explicit configuration, implicit configuration, or a combination thereof. A user equipment, UE, may be configured with a resource pool configuration, for example, pertaining to multiple resource pools, resource group partitions, and/ or component carrier groups. The UE may be configured to use fields such as a Carrier Indication Field and/or a Carrier Group Indication Field contained in a Physical Sidelink Control Channel, PSCCH. The UE may use the resource pool configuration in combination with where the UE is able to decode the PSCCH, with or with the C1F and/or CG1F, to determine a scheduled Component Carrier, CC, for sidelink communications.

The method includes a step of selecting, via a gNodeB, a spatial filter from a first set of spatial filters to perform listen before talk (LBT). The method includes a step of detecting, via the gNodeB, a channel in an idle state,. The method also includes a step of obtaining, a directional channel occupancy time (COT) in the channel in a direction of the selected spatial filter. The method also includes a step of transmitting, to a node, a channel access indicator transmission (CAI-T) on a beam in the cot via a spatial filter of a second set of spatial filters. The method further includes a step of receiving, from the node, a channel access indicator response (CAI-R). The method further includes a step of sensing, via short channel sensing and via the spatial filter or another spatial filter of the second set of spatial filters, the channel is clear. The method even further includes a step of sending, via the channel, information to the node using one or more spatial filters of the second set of spatial filters.

Abstract: An electronic device including a transceiver to communicate with a network; and circuitry. The circuitry is configured to perform beam failure detection on a monitored cell; detect a beam failure on the monitored cell; determine at least one new set of candidate beam reference signals (CB-RSs) from at least one set of CB-RS configured for the device; determine if any CB-RS in the at least one new set of CB-RSs meets a criterion, and in a case that any CB-RS in the at least one new set of CB-RSs meets the criterion: select a beam corresponding to a CB-RS in the new set that meets the criterion as the new beam, and indicate the selected new beam to the network; and in a case that no CB-RS in the new set of CB-RS meets a criterion, indicate to the network that no CB-RS in the new set meets the criterion.

Abstract: A discoverer user equipment sends a discovery announcement to a discoveree user equipment via a sidelink service. The announcement includes criteria for a service sought by discoverer. The discoveree assesses the announcement and may respond to the discoverer. The discovery announcement may be a target search discovery announcement or a self-advertisement discovery announcement, and may be unicast, groupcast, or broadcast. The discoverer and discoveree may perform synchronization in support of V2X sidelink communication and may collect driving information pertaining to vehicles associated with the discoverer and discoveree, respectively, such as driving intention, positioning, and environment information. The discoverer may request an authorization for the discovery announcement, and the request may include the driving information. The information in the announcement and the response may include discoverer and discoveree service, platform, and radio capabilities, source identifiers, driving information, radio measurements, group identifiers, and protocol configuration parameters.

Abstract: Methods and apparatuses are described herein for uplink control information (UCI) design for uplink (UL) transmission with configured grants. In accordance with one embodiment, a wireless communications device may receive, from a gNB, first information indicating a plurality of resources for a configured grant (CG) on a physical uplink shared channel (PUSCH). The wireless communications device may determine, based on second information, a portion of the plurality of resources to use for transmitting a configured grant-uplink control information (CG-UCI). The wireless communications device may generate the CG-UCI, wherein the CG-UCI comprises at least one of: an identifier associated with the wireless communications device or an indication of a modulation and coding scheme (MCS). The wireless communications device may transmit, to the gNB on the PUSCH, the CG-UCI using the determined portion of the plurality of resources.

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.
