Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may be configured for carrier aggregation (CA) in which a plurality of component carriers (CCs) are aggregated. The UE may determine a mapping of the CCs to a plurality of antenna panels for downlink reception, wherein a subset of the CCs are mapped to each antenna panel. The UE may transmit, to the gNB, radio resource control (RRC) signaling that indicates information related to the mapping. The gNB may, based at least partly on the mapping, determine, for each CC: a first scheduled time period for transmit beam refinement, and a second scheduled time period for receive beam refinement at the UE.

Abstract: Apparatuses, systems, and methods for performing uplink transmissions during a dual active protocol stack handover. A wireless device may determine a propagation delay between the wireless device and each of a source cell and a target cell of a dual active protocol stack handover by the wireless device. The wireless device may provide an indication to the source cell of the propagation delay between the wireless device and the source cell, the propagation delay between the wireless device and the target cell, and a propagation delay difference handling capability of the wireless device. The cellular base station that provides the source cell may determine a time division multiplexing pattern for uplink communication for the wireless device during the dual active protocol stack handover based at least in part on the information provided by the wireless device.

Abstract: Methods to enhance the coverage of NR systems for coverage-limited wireless devices are disclosed. A serving base station may configure a coverage-limited UE with parameters for the UE to operate in a coverage enhancement mode through RRC signaling, DCI, or RAR grant. The UE may use the configuration parameters to determine whether to enter into the coverage enhancement mode when connecting and communicating with the serving base station. The configuration parameters may configure the UE to exploit both time diversity and frequency diversity to extend and enhance coverage when receiving PDSCH and PDCCH channels. The UE may use the configuration parameters to receive PDSCH and PCCCH that are coverage enhanced using time repetitions and frequency hopping. Advantageously, the base station may flexibly and dynamically configure the UE with coverage enhancement parameters to extend the coverage of the UE using time diversity and frequency diversity gains as the UE moves around.

Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for adequately measuring reference signals while a user equipment (UE) uses beamforming for optimal receiving. Embodiments describe how a UE may measure received-beamformed reference signals as well as how to determine a reported value while multiple beams are measured or a receiver diversity is in use by the UE. Other embodiments may be described and claimed.

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: The present application relates to devices and components including apparatus, systems, and methods to perform measurements on reference signals based on measurement gaps. In an example, a device supports a frequency range that includes frequencies equal to or larger than 52.6 GHz. Measurement gap capability information is used to indicate and/or determine whether a measurement gap is supported for this frequency range. If so, measurement gap configuration can be defined and can include a measurement gap length and/or a measurement gap repetition period defined based on the frequencies being equal to or larger than 52.6 GHz.

Abstract: Embodiments of the present disclosure enable a user equipment (UE) to performing inter-Radio Access Technology (RAT) measurements. The UE determines whether one or more inter-RAT measurement object (MO) is configured with or without a measurement gap (MG). When the one or more inter-RAT MO is on an NR serving component carrier (CC) with the MG, the UE performs an inter-RAT measurement on the NR serving CC based on whether the MG is fully overlapped or partially overlapped with synchronization signal blocks (SSBs) of a target MO of the one or more inter-RAT MO. When the one or more inter-RAT MO is on the NR serving CC without the MG, the UE performs the inter-RAT measurement on the NR serving CC based on whether a target SSB of the target MO is within or outside an active bandwidth part (BWP) of the NR serving CC.

Abstract: Techniques for selecting the number of sounding reference signal (SRS) resources to be used by a user equipment (UE) operating in a wireless communications system are provided. The UE determines a degree of partial beam correspondence of the UE and compares the degree to a threshold amount of partial beam correspondence support of the UE. In response to the comparison, UE selects a number of sounding reference signal (SRS) resources to request from a network node and sends a SRS resource request message to the network node to request the selected number of SRS resources.
