Abstract: A location management function (LMF) of a network provides timing errors to user equipment and/or base stations for positioning purposes. The LMF receives an indication of an effective timing error for a downlink time difference of arrival (DL-TDOA) positioning technique, wherein the effective timing error is associated with a set of base stations configured to transmit positioning reference signals for the DL-TDOA and provides the effective timing error to a user equipment (UE) performing operations related to the DL-TDOA.

Abstract: Some embodiments include a system, apparatus, article of manufacture, method, and/or computer program product and/or combinations and sub-combinations thereof, for implicit 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 including a first Physical Downlink Control Channel (PDCCH) monitoring periodicity, KS1, and operate in an On-state for a duration of KS1. The NCR can detect a skipped PDCCH monitoring periodicity, and operate in an Off-state for a duration corresponding to the skipped PDCCH monitoring periodicity. In some embodiments, the NCR operates with a carrier component (CC) with unpaired spectrum supporting slot configurations time division duplex (tdd)-uplink (UL)-downlink (DL)-ConfigurationCommon or tdd-UL-DLConfigurationDedicated. The NCR can detect from a System Information Block (SIB), a flexible orthogonal frequency division multiplexing (OFDM) symbol, and operate in an Off-state for a duration of the flexible OFDM symbol.

Abstract: A user equipment (UE) is configured to receive synchronization signal blocks (SSBs) from a wireless network to estimate frequency and timing errors. The UE receives a quasi co-location (QCL) configuration between a synchronization signal block (SSB) and at least one of a further SSB or a tracking reference signal (TRS), receives the SSB and the at least one of the further SSB or the TRS and estimates a frequency and timing error for the SSB by combining, based on the QCL configuration, measurements for the SSB and measurements for the at least one of the further SSB or the TRS.

Abstract: The present disclosure is directed to AP-SRS triggering offset enhancement for further enhanced MIMO. User equipment (UE), base stations, apparatus, methods, computer-readable memory media, and computer program products are disclosed. The UE may be configured to receive an offset information associated with AP-SRS transmission of the UE; determine a slot offset associated with the AP-SRS transmission, at least based on the offset information; determine a specific slot for the AP-SRS transmission, based on the determined slot offset; and perform the AP-SRS transmission in the determined specific slot.

Abstract: A user equipment (UE) is provided to implement a set of transmit power control (TPC) commands during a time domain window (TDW) including multiple physical uplink shared channel (PUSCH) transmissions. The UE can receive a configuration from the base station to configure the UE to support a power control mode and a timeline measurement related to a PUSCH transmission. The UE can receive a set of TPC commands during the TDW, determine whether a TPC command of the set of TPC commands satisfies a time constraint based on the timeline measurement, determine an effective TPC command for the set of TPC commands based on one or more TPC commands satisfying the time constraint, determine an effective delay for the effective TPC command based on the timeline measurement, and further apply the effective TPC command to a PUSCH transmission determined based on the effective delay of the effective TPC command.

Abstract: This disclosure provides details of sequence-based WUS design and signaling, also DCI-based WUS design which also serves as scheduling DCI. For sequence-based WUS there are two variants. A first is based on CSI-RS, that is relatively wide band so the sequence occupies wider band compared to SSB transmission. The second is more akin to the Secondary Synchronization Signal (SSS) type of sequence in that it occupies a narrower band over the entire bandwidth.
