    Abstract: Techniques for observed time difference of arrival (OTDOA) positioning based on heterogeneous reference signals (RSs) are discussed. One example apparatus configured to be employed within a user equipment (UE) comprises receiver circuitry, a processor, and transmitter circuitry. The receiver circuitry can receive, from each of a plurality of evolved Node Bs (eNBs), one or more RSs of each of a plurality of distinct types of RSs. The processor can determine, for each of the eNBs, a time of arrival (TOA) of the one or more RSs of each of the plurality of distinct types of RSs; and compute, for each of the eNBs, a reference signal time difference (RSTD) based at least in part on the TOAs of the one or more RSs of each of the plurality of distinct types of RSs. The transmitter circuitry can transmit the RSTD computed for each of the eNBs.

    Abstract: Provided is a method for a user equipment (UE), comprising performing, based on acquired information, in at least one of an idle mode and an inactive mode, at least One of an intra-frequency neighbor cell measurement and an inter-frequency neighbor cell measurement. The acquired information comprises at least one of a group of a periodicity of synchronization signal and physical broadcast channel block (SSB)-based measurement timing configuration (SWTC) and a periodicity of SMTC2-long periodicity (SMTC2-LP) and a physical cell identifier (PCI) list of SMTC2-LP.
