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: 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.

Abstract: Aspects are described for a user equipment (UE) comprising a low power wake up radio (LP-WUR) and a main radio configured to enable wireless communications with a base station, and a processor communicatively coupled to the LP-WUR and the main radio. The processor is configured to receive a first low power wake up signal (LP-WUS) from the base station; determine that the first LP-WUS corresponds to a cell of the UE; and determine that the first LP-WUS indicates powering on the main radio. The processor is further configured to turn on the main radio and receive a paging message from the base station.

Abstract: Triggering 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 for transmission to the UE may be encoded. The RRC UL gap configuration may include configuration information associated with at least one of a periodicity, offset, or length. Measurement information received from the UE may be decoded. The measurement information may include at least one of a power headroom value, a PCMAX,f,c value, or a P value. Based on the power headroom value, the PCMAX,f,c value, or the P value, the UL gap configuration may be activated by encoding a medium access control (MAC) control element (MAC CE) for transmission to the UE.

Abstract: Methods and systems are disclosed for a UE to perform measurements of measurement resources transmitted by a network when the UE is configured with multiple concurrent measurement gap patterns (MGPs). The measurement resources may be carried on multiple carrier frequencies. The UE may receive measurement resource configuration parameters identifying time and frequency locations of the measurement resources transmitted on the multiple carrier frequencies. The UE may receive measurement gap configuration parameters for multiple concurrent MGPs specifying measurement intervals that may be used to perform the measurements. The UE may determine a linkage between the measurement resources on a carrier frequency and one of the concurrent MGPs so that the UE may independently measure the measurement resources received on the multiple carrier frequencies using their respectively linked MGPs. The linkage may be made through information elements in the measurement resource configuration parameters or the measurement gap configuration parameters containing the MGP.
