Abstract: Apparatuses, systems, and methods for providing downlink control for multi-TRP transmission. A cellular base station may provide a downlink control information transmission to a wireless device scheduling downlink transmissions to the wireless device from multiple transmission reception points. The downlink control information may include information that can be used by the wireless device to determine any or all of physical resource block bundling sizes, frequency domain resource allocations, modulation and coding schemes, redundancy versions, phase tracking reference signal configurations, and any of various other possible types of configuration information for the downlink transmissions. The wireless device may receive the downlink transmissions from the plurality of transmission reception points in accordance with the downlink control information.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to perform downlink control information (DCI) mode signaling and control resource set (CORESET) selection. A DCI mode may be signaled based on a predefined rule, media access control (MAC) control element (CE), and/or group based beam reporting. One or more CORESETs may be selected based on configuration of an active bandwidth part (BWP), CORESET identifier, higher layer index, periodicity, type of search space, and/or MAC CE.

Abstract: TDD configuration may be dynamically and/or semi-statically signaled to user equipment devices by a base station. Semi-static TDD configuration may include: an initial portion for downlink transmission; a flexible portion; and a terminal portion for uplink transmission. TDD structure of the flexible portion may be determined later by transmission of dynamic physical layer configuration information such as downlink control information (DCI) and/or slot format indicator (SFI). (The SFI may be included in a group common PDCCH of a slot.) The downlink portion and/or the uplink portion may include subsets whose nominal transmit direction is subject to override by transmission of dynamic physical layer configuration information.

Abstract: This disclosure relates to providing synchronization signal block index signaling in a cellular communication system. A cellular base station may provide synchronization signals according to a periodic pattern, including transmitting one or more synchronization signal bursts each including one or more synchronization signal blocks. A wireless device may detect a synchronization signal block. The wireless device may determine a synchronization signal block index of the detected synchronization signal block. The wireless device may provide an indication of the synchronization signal block index of the detected synchronization signal block to the cellular base station.

Abstract: A wireless user equipment (UE) may employ any of various mechanisms for reporting signal quality measurements to a wireless network. The UE may impose a time delay between measurement and reporting, based on a delay parameter K. The UE may average measurements obtained at different measurement instances. The UE may employ any of various schemes for prioritizing transmission of one type of report over another, when temporal collisions occur between different types of report. The UE may employ a differential report that includes a state for indicating that a beam is not workable. The UE may employ a beam index that includes a state for indicating an invalid beam. A base station may receive a signal quality report and determine workability of a beam, e.g., by triggering a report of channel state information.

Abstract: 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.

Abstract: A device may obtain, through wireless signaling from a network, a time-domain wireless-resource allocation (TWRA) pattern allocated to the device by the network and corresponding to a future time interval (TTI) for which the device has not yet decoded corresponding control information. This enables the device to conduct wireless communications during the TTI using resources allocated according to the obtained TWRA pattern, without first having to decode control information to identify the TWRA pattern. The device may obtain the TWRA pattern by obtaining an indication from the network that the TWRA pattern remains associated with future wireless communications of the device until indicated otherwise by the network, and/or by transmitting to the network an indication of preferred parameters associated with the future wireless communications and the TWRA pattern, and/or by transmitting to the network a request to have the network change from a different TWRA pattern to the TWRA pattern.
