摘要： This disclosure relates to performing cellular communication using a power efficient downlink control information framework. A wireless device and a cellular base station may exchange configuration information indicating that the cellular base station and the wireless device support a sleep downlink control information (sDCI) format. An sDCI configuration according to the sDCI format may be negotiated, including selecting at least one sDCI configuration parameter based at least in part on an application type currently associated with cellular communication between the cellular base station and the wireless device. Downlink control information may be provided during one or more subframes in accordance with the sDCI configuration. One or more subframes for which no downlink control information will be provided to the wireless device may be determined based at least in part on the sDCI configuration.

摘要： 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.

摘要： Apparatuses, systems, and methods for providing downlink control for non coherent joint transmission. A cellular base station may provide downlink control information associated with a non coherent joint transmission downlink data communication to a wireless device, which may receive the downlink control information. The downlink control information may be provided as a single downlink control information including scheduling information for two data streams of the non coherent joint transmission data communication, or a portion of a multi-stage downlink control information transmission. The wireless device may receive the non coherent joint transmission downlink data communication based at least in part on the downlink control information.

摘要： Apparatuses, systems, and methods for a wireless device to perform beam management procedures with a base station. A wireless device in communication with a 5G base station may perform measurements and determine constraints relevant to beam selection. The device may select a recommended beam based on the measurements and constraint(s) and indicate the recommended beam to the base station. A recommended uplink beam may not correspond to a recommended downlink beam.

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： 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： Embodiments are presented herein for adjusting the conduct of routine communications of safety messages in V2X networks in order to conserve resources in participating power-limited devices while satisfying V2X system latency demands. Scheduling (e.g., timing and/or frequency) of safety message communications performed by certain UE devices participating in a V2X network may be dynamically adjusted according to various criteria, such as factors relating to the DRX cycle schedule, motion or mobility, traffic environment, and/or battery or power capabilities of the UE devices, which may conserve UE resources and power consumption. Certain UE devices may efficiently transmit safety messages to the V2X network using one of several proposed RACH-based procedures. In some embodiments, the size of safety message communications may be reduced through various compression techniques, and/or by reducing the amount of contained information, e.g., by omitting certain parameters, which may reduce the resources consumed by performing safety message communications.
