Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform intra-UE co-existence between non-stand-alone (NSA) and stand-alone (SA) mode. The UE may be configured to connect to a first radio access network (RAN) operating according to a first radio access technology (RAT) via a first radio and connect to a second RAN operating according to a second RAT via a second radio. The UE may provide, to the first RAN, configuration information during a radio resource control (RRC) connection procedure. The configuration information may indicate a dual connectivity status of the UE. The dual connectivity status may include indication disabling (enabling) dual connectivity for the UE, working frequencies associated with the second RAN, and/or configurations associated with the second RAN. The UE may receive, from the first RAN, a dual connectivity configuration that may be based on the dual connectivity status of the UE and operate accordingly.

Abstract: This disclosure relates to techniques for performing consecutive conditional handovers. A cellular base station may provide conditional handover information for multiple conditional handovers to a wireless device. The conditional handover information may include information for performing a conditional handover from a cell provided by the cellular base station to at least one cell, and information for performing a conditional handover from one or more of those cells to at least one cell. The wireless device may perform multiple consecutive conditional handovers using the conditional handover information.

Abstract: This disclosure relates to systems, apparatuses, and methods for coordinating communication and avoiding and/or mitigating collisions for multi-subscriber identity module devices in a wireless communication system. A wireless device may coordinate communication associated with different subscriber identity modules and/or may mitigate collisions between communications associated with different subscriber identity modules. A network may provide information to improve coordination and/or mitigate collisions. A network may adjust paging schedules and/or provision of alert messages to improve coordination.

Abstract: This disclosure relates to performing bandwidth part activation in a cellular communication system. A wireless device may attach to a network via a cell that includes multiple bandwidth parts. The wireless device may receive an indication activating a non-default bandwidth part for the wireless device. A bandwidth part activation timer may be initiated based at least in part on activation of the non-default bandwidth part. At expiration of the bandwidth part activation timer, the wireless device may deactivate the non-default bandwidth part and activate a default bandwidth part if there is not a procedure to perform an uplink data transfer in progress. If there is a procedure to perform an uplink data transfer in progress at expiration of the bandwidth part activation timer, the procedure may be completed via the non-default BWP even after expiration of the bandwidth part activation timer.

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: Apparatuses, systems, and methods for a wireless device to perform single transmitter dual connectivity cellular communication. The wireless device may establish a radio resource control connection with a base station. The wireless device may provide an indication of radio frequency capability information for the wireless device to the base station. Providing the radio frequency capability information for the wireless device may affect whether and how the wireless device is configured for dual connectivity cellular communication.

Abstract: Apparatuses, systems, and methods for a wireless device to perform substantially concurrent communications with a next generation network node and a legacy network node. The wireless device may be configured to stablish a first wireless link with a first cell according to a RAT, where the first cell operates in a first system bandwidth and establish a second wireless link with a second cell according to a RAT, where the second cell operates in a second system bandwidth. Further, the wireless device may be configured to perform uplink activity for both the first RAT and the second RAT by TDM uplink data for the first RAT and uplink data for the second RAT if uplink activity is scheduled according to both the first RAT and the second RAT.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for configuring a power savings signal in fifth generation (5G) new radio (NR) networks. The wireless device may transmit, to a base station within a network, power savings requirements and receiving, from the base station, a configuration of a power saving signal, where the configuration indicates one or more functionalities of the power saving signal. The wireless device may periodically receive, from the base station, the power saving signal and interpret the power saving signal based on the configuration. The configuration of the power saving signal may be received via radio resource control signaling.

Abstract: A user equipment (UE) device may make measurements of network-configured frequencies in an idle mode or an inactive mode, and report the measurements to the network during (or after) a connection establishment or a connection resume process. The initiation of measurements may be delayed until a connection is imminent or until an upper layer request. A result timer may be used to ensure that reported measurements are not too old to be of use. A configuration timer may be used to selectively report inter-frequency/RAT cell measurements. The configuration timer may also be used repeatedly in conjunction with intervening backoff periods. A base station of the network may use the measurements to make informed decisions on when and how to configure carrier aggregation or dual connectivity for the UE device.
