Abstract: An approach to reduce the signaling overhead for tracking reference signal (TRS) configuration signaling to idle and inactive user equipments (UEs) operating in a wireless communication system. Conventional signaling approaches require more bits that can be conveyed in the maximum system information block (SIB) message size. One proposed approach optimizes the signaling by removing unnecessary or redundant information, using a single TRS configuration to replace multiple configurations, size reduction in some fields, and the sharing of some fields across different TRS configurations. Another proposed approach uses an SIB message to carry the TRS configurations for a particular beam or subset of beams. These two proposed approaches may be combined to provide further optimization possibilities.

Abstract: Systems and methods for improving the robustness of a DCI triggered beam update in 5G NR are disclosed herein. A g Node B (gNB) may associate a reference signal to a beam pattern (or beam configuration) and prepare Downlink Control Information (DCI) of a Physical Downlink Control Channel (PDCCH) that includes aperiodic Channel-State Information Reference Signal (AP CSI-RS) information indicating the beam pattern. A user equipment (UE) may decode the DCI, extract the AP CSI-RS information, update the beam pattern of a reference signal based on the AP CSI-RS information, and generate an uplink (UL) feedback message indicating that the PDCCH was successfully decoded by the UE. The gNB may then decode the uplink (UL) feedback message and, in response, update a receive (RX) beam of the gNB to correspond to the beam pattern associated to the reference signal.

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: A method, UE and integrated circuit for reporting RSTD values to a network. A user equipment (UE) is configured to establish a connection to a network, the network comprising a first cell and a second cell. The UE receives a positioning reference signal from each of the first and second cells, determines a frequency band for each of the positioning reference signals, determines reference signal time difference (RSTD) values from measured time offsets between the positioning reference signals from the first and second cells, determines RSTD reporting values based on at least the RSTD values and the determined frequency bands and transmits an indication of the RSTD reporting values to the network.

Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH) in multiple component carriers (CC). The UE determines if the UE is operating in carrier aggregation (CA) mode having a first CC in a first frequency band and a second CC in a second frequency band. When the UE is operating in CA with a first CC in the first frequency band and the second CC in the second frequency band, the UE determines a span pattern for PDCCH symbols being received on the first and second CC and selects a PDCCH monitoring type based on, at least, the span pattern. A UE also determines if a first CC and a second CC of a CA combination are collocated and selects a PDCCH monitoring type based on, at least, the determination of whether the first and second CC are collocated.

Abstract: Approaches are described for receiving downlink signals simultaneously where analog beamforming is being used to increase the link budget between the base station and user equipment (UE). Alternatives within these approaches include the UE determining the synchronization signal block (SSB) to receive when there are multiple SSBs from different cells in a slot, and determining whether there are other signals in the same symbols with the selected SSB based on the type of signal and the SSB's functionality. In the case where there are another downlink signals channel state information-reference signal (CSI-RS) or physical downlink shared channel (PDSCH) from another cell, the UE selects the corresponding quasi co-location (QCL) assumption to receive the signals. Optionally, the UE can report whether it can support one or two QCL-TypeD at a time and whether it supports SSBs in different cells multiplexed in overlapped symbols.

Abstract: Embodiments of the present disclosure relate to Physical Uplink Control Channel (PUCCH) reliability enhancement. According to embodiments of the present disclosure, a processor of a UE receives, from a BS associated with a first TRP and a second TRP, a first message for configuring a PUCCH resource to be used by the UE to perform a PUCCH transmission with the BS. In this case, the first message indicates a first configuration corresponding to the first TRP and the first configuration comprises at least one power control parameter associated with the first TRP. The message further indicates a second configuration corresponding to the second TRP and the second configuration comprises at least one power control parameter associated with the second TRP. The processor performs the PUCCH transmission with the BS via the first and second TRPs based on the first message. In this way, the reliability and robustness of the PUCCH transmission for multiple TRP is enhanced.
