    Abstract: Systems and methods using control signaling for uplink frequency selective precoding at a user equipment (UE) are disclosed herein. A base station may indicate a transmission rank indicator (TRI), a wideband transmission precoder matrix indicator (TPMI), and one or more subband TPMI(s) to the UE. The base station may indicate, to the UE, whether to use the wideband TPMI or a subband TPMI to precode a physical uplink shared channel (PUSCH) transmission from the UE to the base station. The UE then precodes (and transmits) the PUSCH accordingly. Methods of UE application of the indicated subband TPMI(s) to subbands of the bandwidth in which a PUSCH may be transmitted are described. Methods accounting for a UE capability as to non-coherent, partial-coherent, and/or coherent precoding are described. Methods of assigning TPMI(s) to subbands in view of multiple transmission reception point (TRP) use by the UE for UE transmission are described.

    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.
