Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform a switch of a TCI state from a serving cell to a neighbor cell. A UE determines whether the state of the neighbor cell is known or unknown and whether the neighbor cell's TCI state is known or unknown. The total delay time to perform the TCI state switch can impacted by this the known/unknown statuses. Other factors can also contribute to the total delay time. The UE may also signal its capability to monitor the TCI state of the neighbor cell and its capability to switch to such a TCI state.

Abstract: A system, method, and apparatus is provided for performing testing using arrival of angles (AOA). The system, method, and apparatus can receive a first test signal from a first cell; receive a second test signal from a second cell; and perform a test based on AOA of the first test signal and the second test signal. At least one of the first test signal and the second test signal can include a channel state information-reference signal (CSI-RS) signal or a synchronization signal block (SSB) signal. The first test signal can include a different number of SSBs transmitted during an Measurement Timing Configuration (MTC) window when compared to the second test signal. The system, method, and apparatus can receive the first test signal and the second test signal in a time division multiple access (TDMA) manner. The first cell can include a serving cell and the second cell can include a neighboring cell of the serving cell. The system, method, and apparatus can receive the first test signal using a main lobe of an antenna and the second test signal using a side lobe of the antenna.

Abstract: Methods and systems to activate beams for beam switching based on measurements of a downlink reference signal that is QCL Type-D with a downlink pathloss reference signal are disclosed. A UE may measure and report to a base station the RSRP of the reference signal that is QCL Type-D with a target downlink pathloss reference signal. Based on the reported RSRP measurements, the base station may activate the target pathloss reference signal to command the UE to update the pathloss measurements of the target pathloss reference signal for uplink power control of a beam corresponding to the target pathloss reference signal. The UE may determine whether the target pathloss reference signal is considered known for uplink power control based on the timing relationship among the reception of the reference signal from the base station, the transmission of the RSRP measurement of the reference signal, and reception of the activation command.

Abstract: A user equipment (UE), baseband processor or other network device (e.g., base station, next generation NodeB, etc.) can operate to process or generate measurement gap configurations associated with multiple universal subscriber identity modules (MUSIM) with dual subscriber identify modules (SIMs). A UE can perform a system information request or an SI reading with or without the SI request based on a UE configured interruption or a preconfigured measurement gap configuration to read a system information block (SIB) 1 and at least one other SIB of SI associated with the target network.

Abstract: Activating an uplink (UL) gap at a base station may include decoding a user equipment (UE) UL gap capability report received from a UE. A radio resource control (RRC) UL gap configuration may be encoded for transmission to the UE. A power headroom report (PHR) medium access control (MAC) control element (CE) received from the UE may be decoded. The PHR MAC CE may include at least one of a P value or a power management maximum power reduction (P-MPR) value. Decoding the measurement information may include determining that the P value is equal to one or the P-MPR value is greater than zero. Based on determining that the P value is equal to one or the P-MPR value is greater than zero, the UL gap configuration may be implicitly activated.

Abstract: This disclosure relates to techniques for configuring, performing, and reporting neighbor cell measurements in a wireless communication system. A base station of a serving cell may provide configuration information relevant to performing layer 1 (L1) measurements based on reference signals of one or more neighbor cells. A UE may perform L1 inter-frequency measurements of the neighbor cell(s) based on the configuration. The UE may report the measurements.

Abstract: Provided is a method for a user equipment (UE). The method comprises determining a first time period for the UE, based on whether the UE uses Discontinuous Reception (DRX) and whether the UE uses Measurement Gap (MG). The first time period indicates a respective timing criterion for the UE to determine a time period of maintaining available downlink timing for a reference cell; The method further comprises determining, based on the first time period, a first time threshold for the UE to determine reference cell availability.
