Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for UE baseband-demodulation-performance tests in new radio (NR). An over-the-air (OTA) test environment with optimized signaling over the test interface by enabling feedback in the test system may achieve adequate baseband emulation of multipath utilizing NR reference signals. Various embodiments describe how to realize a test loop initialization and achieve better test certainty and controllability over OTA tests.

Abstract: Apparatuses and methods are disclosed for supporting a UE in reporting of a selection of an NZP CSI-RS resource to an eNB supporting FD-MIMO communication. Each NZP CSI-RS resource is associated with a unique NZP CRI (or ‘Beam Index’) on a given serving cell. The UE may select an NZP CSI-RS resource for CSI calculation and reporting to the eNB based on processed CSI-RS signals received at an antenna of the UE from the eNB of a serving cell of the UE based on a CSI-RS resource configuration for the UE signaled from the eNB. The UE may report a CRI and a CSI of the selected NZP CSI-RS resource to the eNB of the serving cell of the UE based on a CRI reporting configuration of the UE signaled from the eNB.

Abstract: Apparatuses, systems, and methods for multiplexing of PUCCH for beam failure recovery and other signals. A UE may determine a transmission dropping rule and a transmission power scaling rule for a PUCCH which is dedicatedly configured for secondary BFR transmission, such as a PUCCH-BFR, when it is multiplexed with at least one other signal. The PUCCH-BFR and the at least one other signal may be multiplexed in a CC or in multiple CCs. The UE may determine a transmission dropping rule, e.g., so that UE can transmit an uplink signals with higher priority and drop the other uplink signal with lower priority to avoid beam collisions. The UE may determine a transmission power scaling rule, e.g., so the UE may scale transmission power within a CC and/or across CCs. The UE may multiplex the PUCCH-BFR with the at least one other signal according to the rules.

Abstract: The disclosure describes configuration schemes for secondary cell (SCell), bandwidth part (BWP) and physical resource block (PRB) indexing. An apparatus of user equipment (UE) for BWP activation and deactivation operation is disclosed. The apparatus includes baseband circuitry that includes a radio frequency (RF) interface, and one or more processors. The one or more processors are to receive radio resource control (RRC) data via the RF interface, configure a timer for a BWP according to the RRC data, and trigger the timer for the BWP in response to detection of an event associated with an access node after the BWP has been activated.

Abstract: Described is an apparatus of a User Equipment (UE) operable to communicate with a fifth-generation Evolved Node-B (gNB) on a wireless network. The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to process a message comprising an indicator to indicate a number of contention based physical random access channel (PRACH) preambles within a PRACH occasion per Synchronization Signal Block (SSB). The second circuitry may be operable to generate a first PRACH occasion, based on the indicator.

Abstract: Some embodiments of this disclosure include apparatuses and methods for uplink panel selection with power saving. In some embodiments, user equipment (UE) may experience a positional change. In response, the UE may deactivate a first communication panel to save power and activate a second communication panel. The UE may then transmit a status message to a communication node indicating the activation and/or deactivation. The node may then register this activation and/or deactivation. In some embodiments, the node may monitor uplink slots from the first and second communication panel to identify the activation and deactivation. For example, if the node detects an absence of an uplink signal within a slot threshold, the node may identify the panel as being deactivated. The node may establishing communications with another panel based on a detected signal and/or the status message.

Abstract: Wireless communication systems can include multiple Transmission and Reception Points (TRPs). Systems, devices, and techniques for control signaling of Precoding Resource block Group (PRG) size configuration for multi-TRP operations are described. A described technique includes determining, by a User Equipment (UE), a PRG size based on a downlink control information (DCI) message that provides scheduling information for a physical downlink shared channel (PDSCH); receiving, by the UE, a group of PDSCH transmissions from multiple TRPs that are transmitted in accordance with the DCI message; and decoding, by the UE, one or more of the PDSCH transmissions based on the PRG size.

Abstract: Provided herein are method and apparatus for configuration of a Reference Signal (RS) and a Tracking Reference Signal (TRS). An embodiment provides a method for a user equipment (UE), including determining a number of slots for a Tracking Reference Signal (TRS), wherein the number of slots is based on a subcarrier spacing of a bandwidth part (BWP) in a current component carrier for the UE; and receiving TRS based on the number of slots and a quasi co-location (QCL) relationship of the TRS, wherein the QCL relationship indicates that the TRS is Quasi-Co-Located (QCLed) with a Synchronization Signal (SS) block or a Channel State Information Reference Signal (CSI-RS).
