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).

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: Technology for a user equipment (UE) operable to multiplex uplink control information (UCI) on a physical uplink shared channel (PUSCH) is disclosed. The UE can determine a symbol duration of the PUSCH. The UE can select a UCI transmission rule in accordance with the symbol duration of the PUSCH when a physical uplink control channel (PUCCH) resource carrying UCI overlaps with more than one PUSCH resource in time within a PUCCH group. The UE can multiplex the UCI on a selected PUSCH resource from the more than one PUSCH resource in accordance with the UCI transmission rule.

Abstract: Systems and methods of beam reporting for multiple DL processes are described. A UE receives a beam management processes configuration that provides information about beam management reference signals for beam management procedures. The UE transmits a UE capability report that indicates beam management capabilities of the UE and, later, an indication of whether the UE intends to engage in beam refinement. The UE measures the beam management reference signals and receives a beam reporting message that indicates at least one of the beam management procedures to report. In response, the UE transmits the beam report. The beam report contains beam management reference signal measurements of the beam management procedures indicated by the beam reporting message.
