Abstract: Systems and/or methods for supporting communications at a reduced bandwidth with a full bandwidth network such as a long-term evolution (LTE) network may be disclosed. For example, inband assignments such as downlink assignments and/or uplink grants may be provided and/or received and transmissions may be monitored and/or decoded based on the inband assignment. Additionally, information (e.g. a definition or configuration) associated with an ePDCCH may be provided and/or received and ePDCCH resources may be monitored and/or decoded based on such information. An indication for support of a reduced bandwidth by the full bandwidth network may also be provided and/or received and control channels in the reduced or narrow bandwidth may be monitored and/or decoded based on the indication. A PRACH preamble and/or a multi-type subframe definition may also be provided and/or used for support of such a reduced bandwidth.

Abstract: Methods and apparatuses are described herein for synchronization enhancement in new radio non-terrestrial networks. In an example. a UE may determine a distance between the UE and a satellite of a NTN. The UE may determine a reference distance associated with the satellite. The UE may determine a differential delay associated with the UE based on the distance between the CE and the satellite and based on the reference distance. Based on the differential delay. the UE may determine a timing advance associated with the UE and the NTN.

Abstract: Methods and apparatuses are described herein to address issues at the MAC layer resulting from potential Listen-Before-Talk (LBT) failures and delayed transmission. For example, a wireless transmit/receive unit (WTRU) may monitor a plurality of TX resource pools within a sidelink bandwidth part (BWP) for LBT events. The WTRU may cause, based on determining that an LBT failure has occurred, a corrective action associated with a sidelink MAC procedure. The WTRU may determine, based on the LBT failure, that a total number or consecutive number of detected LBT failures for one of the monitored TX resource pools exceeds a threshold, indicating a consistent LBT failure. The WTRU may, based on the consistent LBT failure, send an indication of the consistent LBT failure for the TX resource pool to peer WTRUs. and an indication of the consistent LBT failure for the TX resource pool to a serving cell.

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: Methods and apparatuses for controlling a reconfigurable intelligent surface (RIS) to generate one or more modulated symbols may be described herein. The processor may be configured to generate an amplitude of the modulated symbol(s) by activating one or more of the plurality of portions of the RIS. The processor may be configured to generate a phase of modulated symbol(s) by controlling one or more phase shifts applied by one or more activated portions of the RIS. The method may include transmitting the one or more modulated symbols using the RIS. The method may include a RIS-based joint beamforming and/or modulation scheme with low PAPR. The RIS may be divided into one or more portions for attaining various gains. The RIS may be divided into an In-phase and/or Quadrature branches. The method may include an Amplitude-phase shift keying (A-PSK) and/or Quadrature amplitude-phase shift keying (AQ-PSK) joint beamforming and/or modulation scheme(s).
