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 establish 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 simultaneous uplink activity for multiple RATs in the same carrier using multiplexing at a layer above the physical layer. The wireless device may establish wireless links with first and second base stations, respectively, according to first and second radio access technologies (RATs), respectively. The first base station may provide a first cell operating in a first system bandwidth and the second base station may provide a second cell operating in a second system bandwidth. The wireless device may determine whether inter-RAT uplink coexistence in the same frequency band is enabled. If so, the wireless device may perform uplink activity for both the first RAT and the second RAT in the first system bandwidth by multiplexing uplink data for the first RAT and uplink data for the second RAT at a layer above the physical layer.

Abstract: A device and method for power saving between a scheduling request and a grant. A user equipment (UE) establishes a connection to a network, the UE and the network may be configured with a Connected Discontinuous Reception (C-DRX) functionality, the C-DRX functionality including a cycle with at least one onDuration. The UE transmits, during a first subframe a scheduling request (SR) to the network, the SR corresponds to data that is to be transmitted by the UE. The UE determines a second subframe for the UE to enter an active mode of processing for a reception of a grant, the second subframe is subsequent to the first subframe and prior to a next onDuration. The UE initiates an active mode of processing for the reception of the grant during the second subframe.

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: A user equipment device may determine whether to power down one or more components based at least on a scheduling parameter that includes an indication of cross-slot scheduling. The device may power down the one or more components prior to decoding control information during a slot for which the scheduling parameter indicates that cross-slot scheduling is in place.

Abstract: Apparatuses, systems, and methods for providing downlink control for multi-TRP transmission. A network-side device may provide a downlink control information transmission to a wireless device scheduling downlink transmission to the wireless device from multiple transmission reception points. The downlink transmission may relate to Hybrid automatic repeat request process and/or system information transmission. And the downlink control information may include information about scheduling of HARQ processes from different TRPs, and/or information about scheduling of SI transmission from different TRPs. The wireless device may receive the downlink transmissions from the plurality of transmission reception points in accordance with the downlink control information.

Abstract: Apparatuses, systems, and methods for RACH procedures to avoid excessive handover/secondary cell group failures. A base station may declare a handover and/or secondary cell group (SCG) failure and may determine that a failure threshold has been met. The base station may perform a remedial action in response to meeting the failure threshold. The failure threshold may be multi-dimensional, where a first dimension is associated with a number of handover/SCG failures and where a second dimension is associated with a time period in which the number of handover/SCG failures occurred. Further, a third dimension may be associated with a UE mobility state and a fourth dimension may be associated with whether the UE is using FR1 or FR2. The remedial action in response to meeting the failure threshold may include the base station suspending transmission of measurement object configurations for a specified period of time.
