Abstract: A user equipment (UE) in a wireless network including a first next generation NodeB (gNB) and a second gNB for communicating with the UE performs operations. The operations include determining to transmit a first transmission (Tx) stream and a second Tx stream simultaneously to the first gNB and the second gNB for handing over communication with the UE from a first cell to a second cell, wherein the first gNB is a serving gNB in the first cell and the second gNB is a handover target gNB in the second cell and simultaneously transmitting within a same antenna panel of the UE the first transmission stream to the first gNB using a first polarization and the second transmission stream to the second gNB using a second polarization different from the first polarization.

Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for performing radio link monitoring or beam failure detection (RLM/BFD) in, or related to, a new radio (NR) involved network. Various embodiments are directed to adaptive configuration of threshold values for in-sync and/or out-of-sync (IS/OOS) in the NR involved network and adequately performing RLM/BFD. Such RLM/BFD with adaptive IS/OOS configuration may improve measurement accuracy and system performance. Other embodiments may be described and claimed.

Abstract: An approach is described for a user equipment (UE), wherein the UE includes radio front end circuitry and processor circuitry coupled to the radio front end circuitry. The processor circuitry receives a reference signal from a source device via a radio link, wherein the reference signal is one of the synchronization signal block (SSB) signal or channel state information reference signal (CSI-RS). The processor circuitry measures a quality of the reference signal, and measures an evaluation time of the reference signal. The processor circuitry determines a first indicator of the radio link based on the quality of the reference signal, and determine a second indicator of the radio link based on the evaluation time of the reference signal. The processor circuitry then determines a status of a connection of the radio link based on the first indicator and the second indicator of the radio link, and generate a message based the status of the connection. The radio front end circuitry then transmits the message to the source device.

Abstract: Systems and methods of initial acquisition in a NR system are described. A UE receives time and frequency superposed SSBs from a gNB. If the PSS and SSS of each SSB is independent of a block index of the SSB, the UE receives an additional reference signal scrambled by a beam index of the SSB and uses the reference signal to discriminate between the SSBs. The reference signal is FDMed within a null-subcarrier region of the SSB or outside of the SSB. If the PSS and SSS of each SSB is scrambled using the block index, the UE separates the PBCH measurements, iteratively identifies a block index associated with a DMRS of the PBCH with the highest L1-RSRP level measurement, decodes and reconstructs the PBCH, and subtracts the reconstructed PBCH from the SSB before transmitting an indication of the PBCH with the highest L1-RSRP level measurement to the gNB.

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: Techniques are provided for mitigating inter-carrier interference (ICI) due to frequency multiplexed downlink channels with mixed numerologies. For example, a base station allocates, for a user equipment (UE), a first downlink (DL) channel and a second DL channel that are frequency multiplexed in a same bandwidth part (BWP) and have different channel numerologies The base station determines a guard band interval between the first DL channel and the second DL channel based on one or more characteristics of the different channel numerologies, transmits DL transmissions to the UE, over the first DL channel and the second DL channel, using the guard band interval between the first DL channel and the second DL channel.

Abstract: Disclosed is a system and method that allows a user equipment (UE) to perform a wireless measurement. The method configures a characteristic of a channel-state information reference signal (CSI-RS) for tracking of the UE. Also disclosed is a system and method to perform radio resource management (RRM) testing. Testing can include: setting a power level of CSI-RS for tracking to a smaller value that a power level of another RRM reference signal; or setting a negative power offset value of the CSI-RS for tracking to a synchronization signal (SS) of the RRM reference signal; or setting a positive power offset value of the CSI-RS for tracking to a physical downlink shared channel (PDSCH) of the RRM reference signal.
