    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: 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 performing uplink and downlink communication in cell edge scenarios with improved reliability. A wireless device may establish a radio resource control connection with a first cell. The wireless device may determine that a second cell strongly interferes with communication with the first cell. The wireless device may provide an indication that the second cell is a strongly interfering cell to the first cell. The first cell may coordinate with the second cell to transmit data to the wireless device, and to receive data from the wireless device, based at least in part on the indication that the second cell is a strongly interfering cell.

    摘要: A device and method for power optimization for a user equipment (UE) without neighbor cell measurement configuration. The UE may be configured with Connected Discontinuous Reception (C-DRX) functionality including a cycle with an onDuration. The UE may be configured with carrier aggregation (CA) in the unlicensed spectrum including a reference signal (DRS) monitoring timing configuration (DMTC) occasion that occurs outside of the onDuration. The UE determines at least one subframe of the onDuration for the UE to utilize an active mode of processing related to performing measurements corresponding to a cell utilizing the unlicensed spectrum. The UE determines to utilize a sleep mode of processing related to performing the measurements during the DMTC occasion based on detecting a first downlink signal transmitted by the cell during the at least one subframe of the onDuration.

    摘要: This disclosure relates to performing cellular communication using a control information monitoring framework. A wireless device may monitor a control channel for control information according to a first periodic pattern. According to the first periodic pattern, the wireless device may monitor the control channel in a specified slot during each period of the first periodic pattern. Each period of the first periodic pattern may include multiple slots. The wireless device may receive control information during a first slot. The first slot may be a specified slot according to the first periodic pattern. The control information received during the first slot may schedule a data communication. The wireless device may monitor the control channel for control information in at least one slot that is not specified according to the first periodic pattern based at least in part on receiving control information during a specified slot according to the first periodic pattern.

    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.
