Abstract: Apparatuses, systems, and methods to dynamically indicate preference for self-contained slots and slot duration by a user equipment device (UE) in communication with a base station (e.g., a gNB) using a 5G NR radio access technology. A UE may determine to send an indication to a gNB indicating a preference for self-contained slots and slot duration for downlink and/or uplink communications utilizing one or more of the physical downlink control channel (PDCCH), the physical downlink shared channel (PDSCH), and/or acknowledgement messaging (ACK/NACK) for downlink communications, and utilizing one or more of the physical uplink control channel (PUCCH), the PDCCH, and/or the physical uplink shared channel (PUSCH) for uplink communications. The configuration of self-contained slots and slot duration for uplink and/or downlink may be based on one or more of average packet size, average packet rate, traffic type and UE processing capabilities.

Abstract: Various mechanisms for paging link-budget-limited (LBL) devices are disclosed. The network node informs a base station of the device's LBL status as part of a paging message and the device is paged either with a dedicated P-RNTI and/or with a particular boosting.

Abstract: Systems and methods are provided for a user equipment (UE) to perform frequency offset (FO) delta tracking. For an anchor component carrier (CC), the UE wakes up to perform tracking updates on a plurality of successive DRX cycles. For the non-anchor CC, the UE determines a minimum update interval Δt upd , and schedules wake-ups on a first subset of the plurality of successive DRX cycles based on the minimum update interval Δt upd . For the first subset of the plurality of successive DRX cycles with scheduled wake-ups, the UE performs the tracking updates on the non-anchor CC and updates an FO delta between the anchor CC and the non-anchor CC. For a second subset of the plurality of successive DRX cycles without the scheduled wake-ups on the non-anchor CC, the UE applies the FO delta to correct for a frequency error.

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 to implement mechanisms for performing a listen again after talk procedure to detect collisions over an access medium. The wireless device may determine a frequency and configuration of modified transmission frames for transmission over an access medium (licensed or unlicensed) and may further determine a timing of the modified transmission frames within a transmission occasion. The wireless device may detect, during a listening period of the modified transmission frame, a collision and may adjust, based, at least in part, on the detected collision, a remaining transmission schedule for the transmission schedule and/or LBT parameters.
