    摘要: Apparatuses, systems, and methods for a wireless device to perform a method including a user equipment device (UE) exchanging communications with a base station to determine one or more scheduling profiles, such as one or more scheduling-power profiles, where a scheduling-power profile may specify one or more parameters associated with UE communication behavior, e.g., one or more constraints on UE communication behavior and/or slot scheduling of UE communications. In addition, the method may include the UE receiving a slot configuration schedule from the base station. The slot configuration schedule may be based on at least one scheduling-power profile of the one or more scheduling-power profiles. Further, the method may include the UE performing communications with the base station based on the at least one scheduling-power profile.

    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: A downlink control information (DCI), such as a blanking DCI (bDCI) message may be transmitted by a base station (e.g., eNB) and received by a mobile device (e.g., UE). The bDCI may indicate that the eNB will not transmit a subsequent DCI to the UE for a duration of time. The UE may be in continuous reception mode or connected discontinuous reception (C-DRX) mode. The UE may therefore determine to enter a sleep state or take other action. The bDCI may specify an explicit blanking duration, or an index indicating a blanking duration from a lookup table, and/or the blanking duration (and/or a blanking duration offset value) may be determined in advance, e.g., semi-statically. When the UE is in C-DRX mode, the UE may be configured such that either the sleep/wake period of the C-DRX mode or the blanking period of the bDCI may take precedence over the other.

    摘要: Apparatuses, systems, and methods for a wireless device to perform methods to implement mechanisms for a UE to request a beam quality measurement procedure. A user equipment device may be configured to perform a method including performing transmitting a request to perform a beam quality measurement procedure for downlink receptions (e.g., a P3 procedure) to a base station/network entity, receiving instructions to perform the beam quality measurement procedure from the base station, and transmitting results of the beam quality measurement procedure to the base station. In some embodiments, transmission of the request may be response to at least one trigger condition and/or detection of a condition at the UE. The request may include an indication of a preferred timing offset. The instructions to perform the beam quality measurement procedure may include a schedule for the beam quality measurement.

    摘要: A zero static loadline switching regulator can include a controller having an integrating outer control loop that receives a first feedback signal corresponding regulator load and a reference signal and generates an intermediate feedback signal therefrom. The control circuit can also include an inner control loop that receives the intermediate feedback signal and a second feedback signal corresponding to a load on the regulator and generates an error signal used to control switching devices of the regulator. The control circuit can also include a transient response circuit configured to boost the error signal, for a predetermined time period after and responsive to a load transient. The error signal may be boosted to an intermediate value between its saturation level and its full scale level. The intermediate value may be predetermined or may be determined responsive to the magnitude of the load transient.

    摘要: This disclosure relates to techniques for supporting narrowband device-to-device wireless communication, including possible techniques for providing synchronization sequences. A first wireless device may transmit a preamble of a device-to-device wireless communication with a second wireless device. The preamble may include a first synchronization sequence. The first synchronization sequence may include multiple repetitions of a basis sequence, multiplied by a cover code. The basis sequence may span multiple orthogonal frequency division multiplexing symbols.
