Abstract: Embodiments are presented herein of apparatuses, systems, and methods for performing vehicle-to-everything sidelink communication. A wireless device may receive vehicle-to-everything resource pool configuration information and sidelink control information. A number of resource elements allocated for a vehicle-to-everything physical sidelink shared channel may be determined based at least in part on the resource pool configuration information and the sidelink control information. A transport block size for the vehicle-to-everything physical sidelink shared channel may be determined based at least in part on the number of resource elements allocated for the vehicle-to-everything physical sidelink shared channel. A low density parity check base graph may be selected for the vehicle-to-everything physical sidelink shared channel based at least in part on the determined transport block size.

Abstract: A user equipment (UE) communicates with transmission-reception points (TRPs). When the UE generates uplink control information (UCI), it determines a higher layer index (HLI) value to target the UCI to the appropriate TRP. (Possible values of the HLI are associated with the TRPs. ) For UCI on Physical Uplink Control Channel (PUCCH), the HLI value may be determined: based on an HLI value configured for a control resource set (CORESET), or for particular Physical Uplink Control Channel (PUCCH) resources; based on UCI type or spatial relation data or an index related to PUCCH resources. For UCI on a configured-grant Physical Uplink Shared Channel (PUSCH), the HLI value may be based on higher layer signals or an indicator relating to channel sounding on spatial relation data. For UCI on MsgA PUSCH in a two-step random access procedure, the HLI value may be based on PUSCH resource unit or PUSCH opportunity.

Abstract: Apparatuses, systems, and methods for selecting channel access mechanisms in wireless communications, and particularly in 3GPP NR-U. For example, an appropriate listen-before talk (LBT) channel access category (Cat) may be defined for certain messages, such as certain DL and/or UL control messages and certain RACH messages. For other messages, an appropriate Cat may be signaled by the base station, e.g., in a DCI message or SIB. Mechanisms are provided for the base station to signal to the UE certain channel access profile parameters, such as an appropriate LBT Cat, CAPC, and/or CP extension. Mechanisms are also provided for adjustment of contention window duration.

Abstract: Apparatuses, systems, and methods for a wireless device and a cellular base station to support common analog beam steering for band groups. The wireless device may provide an indication of analog beam steering capability of the wireless device to the cellular base station. For example, the wireless device may support a limited number of analog beams for each of one or more band groups. The cellular base station may select beam configuration information for the wireless device based at least in part on the indication of analog beam steering capability of the wireless device. This may include selecting a common beam for multiple component carriers for the wireless device based on the wireless device's analog beam steering capability. The cellular base station may provide the beam configuration information to the wireless device.

Abstract: A device may monitor a first search space (SS) corresponding to an active first component carrier (CC), and detect first control information (CI) that identifies an inactive second CC. In response to receiving the first CI, the device may activate the inactive second CC to make it an active second CC. The device may also set up a second SS corresponding to the active second CC, and may monitor the second SS to schedule the active second CC and receive a physical data channel. The first CI may also include additional scheduling information and a start time for reception of the physical data channel. The device may operate in a first bandwidth part (BWP) according to a first communication configuration associated with the first bandwidth part, and may switch to operating in a second BWP and to operating according to a second communication configuration associated with the second BWP.

Abstract: Apparatuses, systems, and methods for a wireless device to perform a method including performing one or more of periodic beam quality measurements and/or event based beam quality measurements, determining, based at least in part on one or more of the periodic beam quality measurements and/or the event based beam quality measurements, a recommended beam quality measurement configuration, and transmitting, to a base station serving the UE, the recommended beam quality measurement configuration. In addition, the UE may perform receiving, from the base station, instructions regarding the beam quality measurement configuration. The instructions may include instructions to activate, deactivate, and/or modify at least one beam quality measurement configuration. In addition, the instructions may be based, at least in part, on the recommended beam quality measurement configuration.

Abstract: Managing radio resources across dual networks includes a wireless mobile device connecting to a first wireless network using a first radio access technology. The wireless device may notify the first network of a capability to be temporarily non-responsive to the first network while maintaining a signaling connection to the first network. The wireless device may communicate with a second network. The wireless device may return to communicating with the first network subsequent to communicating with the second network, and in response to communicating with the second network for less than a predetermined amount of time, the wireless device may send a scheduling request to the first network. In response to receiving a grant acknowledgement from the first network, the wireless device may send a buffer status report that includes a value such as zero to indicate that the wireless device has returned to and can communicate with the first network.

Abstract: Apparatus and methods for implementing "intelligent" receive diversity management in e.g., a mobile device.. In one implementation, the mobile device includes an LTE-enabied UE, and the intelligent diversity management includes selectively disabling receive diversity (RxD) in that device upon meeting a plurality of criteria including (i) a capacity criterion, and (it) a connectivity criterion. In one variant, the capacity criterion includes ensuring that an achievable data rate associated with a single Rx (receive) chain is comparable to that with RxD.

Abstract: A user equipment (UE) configured to monitor paging occasions of a network. The UE operates in a paging discontinuous reception (DRX) cycle, wherein the DRX cycle includes a paging occasion (PO). The UE determines a location in time for a wake-up signal (WUS) occasion associated with the PO and determines whether to utilize an active mode or a sleep mode during the PO based on an indication included in a WUS received during the WUS occasion.
