Abstract: Mechanisms for reducing the reporting overhead corresponding to spatial domain (SD) basis reporting facilitate reporting of different beams (SD bases) for the different panels, with reduced reporting overhead, compared to independent per panel reporting. For multi-panel precoder reporting, a WTRU may report the SD basis (beam) for a reference panel (reference CSI-RS). For non-reference panels (non-reference CSI-RS), the WTRU may report beam offsets in relation to the beam of the reference panel. The WTRU may determine and report beam offset parameters, e.g., step size and range, based on measurements, e.g., distance. For multi-beam reporting, the multiple beam offsets for a non-reference panel may be associated with the multiple beams by the ordinal positions of the beam offsets in the CSI report.

Abstract: A wireless transmit/receive unit (WTRU) may receive configuration information indicating a plurality of transmission configuration indicator (TCI) states and a plurality of aperiodic (AP) channel state information reference signal (CSI-RS) trigger states. The WTRU may determine that a unified TCI state is applicable. The WTRU may receive DCI scheduling a downlink transmission. For example, the DCI may include information indicating (i) a trigger state, (ii) an applicable RS, and/or (iii) a source RS of the unified TCI state or a previous AP CSI-RS. The WTRU may determine a RS, to apply for the downlink transmission, from the applicable RS, the source RS of the unified TCI state, and the previous AP CSI-RS. The WTRU may receive the downlink transmission using one or more first quasi-colocation (QCL) type properties associated with the determined RS and a second QCL type property associated with the unified TCI state.

Abstract: A wireless device, such as user equipment (UE) or other apparatus, like may use a transparent mode operation in which the device is not aware of the operation mode of abase station, such as a gNB or other transmission and receive point (TRP), via the use of configurations for Frame Based Equipment (FBE) and Load Based Equipment (LBE) operating modes. A base station may initiate a Channel Occupancy Time (COT) that is an FBE COT or an LBE COT, in which the wireless device follows FBE or LBE procedures accordingly. A variety of criteria may be applied in determining whether to use FBE or LBE procedures, and to switch between them. A network may use indicate the intention to switch operation mode and may do so via implicit or explicit indications. Similarly, a wireless device may autonomously switch operation mode, and may indicate the selected mode to the network.

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.

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.
