Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for reducing interferences for Sounding Reference Signal (SRS) by, for example, one or more of frequency domain interference randomization, code domain interference randomization, or power control. For example, a user equipment (UE) can be configured to determine a comb offset and/or a cyclic shift for each Sounding Reference Signal (SRS) transmission occasion for the UE. The comb offset and/or the cyclic shift change between different SRS transmission occasions of the UE. The UE is further configured to transmit an SRS to the base station using the determined comb offset and/or the determined cyclic shift during the SRS transmission occasion corresponding.

Abstract: Some embodiments include a system, apparatus, article of manufacture, method, and/or computer program product and/or combinations and sub-combinations thereof, for explicit power saving operations for a network-controlled repeater (NCR) in a wireless network. Some embodiments include an NCR that can receive a Downlink Control Information (DCI) format comprising an offset indication in a single Physical Downlink Control Channel (PDCCH) monitoring periodicity, KS, where KS is an integer of slots. The NCR can determine a single On-Off Pattern (OOP) within KS based at least on the offset indication, and communicate with a base station or a user equipment (UE) based at least on the determination. In some embodiments, an Off-State of the NCR is a default, and the offset indication identifies a duration of an On-State of the NCR beginning at a starting orthogonal frequency division multiplexing (OFDM) symbol of KS.

Abstract: Apparatus and methods are provided for port selection codebook configuration. A user equipment (UE) may decode a channel state information (CSI) report configuration (CSI-ReportConfig) from a base station. The CSI-ReportConfig configuring a port selection codebook comprising a port selection matrix W1, a combinational coefficient matrix W2, and a frequency basis selection matrix Wf. Based on the CSI-ReportConfig, the determines, for the port selection matrix W1, up to L CSI reference signal (CSI-RS) ports out of P CSI-RS ports configured for measuring and reporting CSI.
