Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products for enhanced system information block, SIB, acquisition in cell-free Multiple Input Multiple Output, MIMO, deployments are described. System information, SI, overhead in cell-free MIMO deployment based on legacy Synchronization Signal Blocks, SSBs, is addressed. Overhead caused by transmission of SI messages in these deployments may be reduced. Enhanced SIB1 message is proposed, in which a WTRU blindly detects the PCI used for SIB1 in a super cell, based on a PCI hypothesis set. A WTRU determines a PCI hypothesis set, e.g., based on previously received SI, the frequency band, the PCI of the detected SSB, etc. The WTRU blindly receives/decodes SIB1 PDCCH, using the PCI hypotheses. The WTRU receives SIB1 PDSCH based on PCI hypothesis used for successfully received SIB1 PDCCH.

Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products are described for enhancement of synchronization signal/physical broadcast channel blocks (SSBs). For example, a number of SSBs associated with a plurality of transmission/reception points (TRPs) may be enhanced using a plurality of physical cell identifiers (PCIs). For example, available or actually transmitted SSBs from a plurality of TRPs may be signaled to wireless transmit/receive units (WTRUs), such as by system information or radio resource control (RRC) signaling. For example, SSB indexing may be enhanced using a plurality of PCIs. For example, a plurality of enhanced SSBs may be transmitted and/or received using frequency resources associated with a legacy synchronization raster or a non-legacy synchronization raster.

Abstract: Multicast/Broadcast Service (MBS) for user equipments (UE) in Radio Resource Control (RRC) idle/inactive modes via signally of MBS frequency ranges and/or switching between frequency ranges as required. Bandwidth Part (BWP) operation for MBS in RRC IDLE and RRC INACTIVE states may be implemented using a dedicated MBS BWP or by sharing a frequency range with other operations. An MBS frequency range may be wider or narrower than an initial BWP used by a UE, for example. MBS frequency range configure may be achieved in a number of ways, such as via Control Resource Set (CORESET), search space, and/or PDCCH monitoring occasions pattern settings for MBS in RRC idle/inactive. Downlink scheduling without dynamic grant for MBS in RRC idle/inactive may include configured scheduling and/or semi-persistent scheduling. Downlink repetition for MBS in RRC idle/inactive may include PDSCH repetition and/or PDCCH repetition.

Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products for transmission configuration indication, TCI, management in near-field, NF, are described. A wireless transmit-receive unit, WTRU, may be configured with multiple TCI sets. Each TCI set may consist of TCI states of NF beams and a TCI state of far-field, FF, beam. The WTRU may determine and may report a preferred TCI set based on measurement on a source reference signal of a TCI state of FF beam. The WTRU may be indicated with an active TCI set and a semi-active TCI set. The active/semi-active status may be switched via downlink control information. The switching delay from semi-active to active status is shorter than from de-active to active status.

Abstract: In an embodiment, a WTRU is configured to apply, to data symbols, a transform-spreading function that spreads the data symbols in a frequency domain, to form a first beam, and to transmit the transform-spread data symbols in the first beam. For example, an embodiment for improving reliability of signal detection over an impaired link includes implementing a Generalized Space-Frequency Block Coding (GSFBC) procedure. The impairment can be caused, e.g., by aging of the channel-state information, imperfections in the channel-state acquisition or reporting procedures, and/or beam-squint effects in multi-antenna systems. And an embodiment can include using hybrid beamforming and a GSFBC procedure to improve reliability of detection of the signal in the presence of beam squint and/or beam misalignments.

Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products for near-field uplink multiple input multiple output. A wireless transmit-receive unit (WTRU) may determine one or more angles of reception of one or more reference signals (RS) transmitted by a network node in direction of the WTRU. In reply, the WTRU may transmit an indicated subset of sounding reference signals (SRS) in the direction of the network node antenna array using a corresponding set of uplink transmission beams that correspond to a beam separation. The network node may determine if the beam separation that the WTRU used was proper. Hence, the WTRU may receive an indication from the network to change, the beam separation. Based on the beam separation indication, the WTRU may change the uplink transmission beams in order to increase or decrease the beam separation, for a subsequent transmission of a subsequently indicated subset of SRS.

A wireless transmit/receive unit measures one or more downlink, DL, reference signals, RSs, to obtain a measurement result, determines, based on the measurement result, at least a first set of vectors, determines, based on the measurement result, at least a second set of vectors having complex valued elements, across which phase progression is non-linear, determines precoder information comprising at least the first set of vectors and the second set of vectors, and transmits, to a transmission reception point, information indicating the precoder information.

Abstract: For a wireless transmit-receive unit (WTRU) moving between near field and far field (NF/FF) regions of a cell, the planar wave approximation used in the FF region may not be adapted to the NF region. Therefore, the WTRU may determine a transmission precoder type of a set of transmission precoder types, and at least one downlink (DL) reference signal (RS). The WTRU may perform one or more measurements based on the DL RS. The WTRU may determine a transmission precoder type from the set of transmission precoder types based on the one or more measurements meeting the associated conditions. The WTRU may transmit a report to the network, the report comprising an indication of the determined transmission precoder type, to be used by the network for DL transmissions to the WTRU, for improved reception of these transmissions by the WTRU in the region where the WTRU is located.
