    摘要： A device may wirelessly communicate according to a first radio access technology (RAT) within a first bandwidth part (BWP) of a frequency spectrum in which wireless communications according to other RAT(s) also take place. The device may be instructed to operate/communicate within a second BWP of the frequency spectrum responsive to the device successfully completing a listen-before-talk (LBT) procedure within a specified portion of the second BWP, where the second BWP contains the first BWP while the first BWP does not contain the specified portion of the second BWP. The device may also be instructed to operate/communicate within a specified frequency band (SFB) of the frequency spectrum responsive to the device successfully completing an LBT procedure within the SFB, where the SFB is not contiguous with the frequency band that includes the first BWP. The device may then simultaneously operate within the second frequency band and the first frequency band.

    摘要： 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.

    摘要： 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.
