Abstract: A WTRU may receive downlink control information (DCI) from a first transmission/reception (TRP). The DCI may indicate that the WTRU is to transmit a physical random access channel (PRACH) transmission. The DCI may include an indication of a preamble, an indication of a first PRACH mask, and/or an indication associated with a first synchronization signal block (SSB), and/or an indication of a reference signal (RS). The WTRU may be configured to transmit the preamble, to a second TRP, the preamble in a first PRACH resource. The first TRP and/or the second TRP may be associated with a same physical cell identity (PCI). The WTRU may receive, from the second TRP, a first response to the preamble. The first response may include a first timing advance (TA) command for the second timing alignment for transmission to the second TRP and/or an index indicating the second TRP.

Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products are disclosed that may be implemented in a wireless transmit/receive unit (WTRU) that is in communication with a base station and/or an intelligent reflecting surface (IRS). For example, the WTRU may operate to facilitate selection of a first beam transmitted from the base station and reflected by the IRS and selection of a reflection parameter set which configures the IRS to reflect the first beam in a manner which may enhance reception of the first beam at the WTRU. As another example, the WTRU may operate to facilitate selection of a beam pair which may include a first beam transmitted from the base station and a second beam transmitted from the base station and reflected by the IRS to the WTRU. The WTRU may receive a configuration which associates particular beams with particular reference signal resources.

Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products may perform channel separation of transmissions associated with a reconfigurable intelligent surface (RIS). In an example, a wireless transmit/receive unit (WTRU) may determine a first channel matrix using measurements of a reference signal (RS) which is associated with first RIS parameter settings, which may impart first reflection properties at the RIS. The WTRU may determine a second channel matrix using measurements of a RS which are associated with second RIS parameter settings, which may impart different second reflection properties the RIS. The WTRU may derive a RIS channel matrix using a function of the first channel matrix and the second channel matrix and determine Channel state information (CSI) therefrom. The WTRU may feedback information indicating the CSI to a base station.

Abstract: Method, apparatus and systems are disclosed that may be implemented in a wireless transmit/receive unit (WTRU). In one representative method implemented in a WTRU, the WTRU may determine a first CSI report associated with a first TRP, and determine a second CSI report associated with a second TRP. A priority between the first CSI report and second CSI report may be determined. The priority (e.g., priorities of the first CSI report and second CSI report) may be based at least in part on whether inter-cell mTRP is configured. One of the first CSI report and second CSI report having a higher priority may be transmitted to a network. Other representative methods relate to blind decoding priority determination, selection of PUCCH configurations, timing advance adjustments and beam application time determination.

Abstract: Systems, methods, and instrumentalities are disclosed herein associated with supporting flexible (e.g., subband-wise) slot format indications, which may include slot type(s) (e.g., new slot type(s)) of ‘Mn’ as a “Mixed” DL/UL. Tx/Rx rules for periodic/semi-persistent configurations according to a subband-wise slot type for XDD may be provided. A search space may be associated with multiple CORESETs. In examples, a WTRU may determine which CORESET to use for monitoring the search space based on the slot type (e.g., XDD slot or non-XDD slot). A WTRU may determine to monitor a search space in an XDD slot based on the “Mn” types and/or the number of search space resources re-allocated for the uplink in the slot. One or more search space sets may be configured and which search space set to monitor may be determined based on the slot type.

Abstract: A wireless transmit/receive unit (WTRU) may be configured to receive one or more slot timing values for transmission of hybrid automatic repeat request (HARQ) acknowledgment (ACK) information bits using first time and frequency resources. The WTRU may be configured to receive configuration information indicating second time and frequency resources for transmission of HARQ-ACK. The configuration information may indicate a set of sequences. The WTRU may be configured to transmit based on HARQ-ACK feedback to be reported for the downlink signals one or more of a first sequence of the set of sequences using the second time and frequency resources, a second sequence of the set of sequences using the second time and frequency resources, or at least one indication of an acknowledgment and at least one indication of a negative acknowledgment using the first time and frequency resources.

Abstract: A wireless transmit receive unit (WTRU) may receive physical uplink control channel (PUCCH) configuration information, SBFD configuration information, and DCI comprising a first PRI. The WTRU may determine that a PUCCH transmission is to be sent. The WTRU may determine, based on a first rule of interpreting the first PRI and the PUCCH configuration information, that a first PUCCH resource indicated by the first PRI is included in at least one frequency resource that is at least partially included in at least one subband for uplink (UL) transmission and one subband for downlink reception indicated by the SBFD configuration information. The WTRU may determine a second PUCCH resource, which may be determined based on a second rule for interpreting the first PRI and the PUCCH configuration information. The second PUCCH resource may be within subbands for UL transmission. The WTRU may transmit the PUCCH transmission using the second frequency resource.

Abstract: A wireless transmit/receive unit (WTRU) may include a transceiver and a processor. The WTRU may be configured to receive one or more downlink signals. The WTRU may be configured to receive configuration information indicating time and frequency resources for transmission of hybrid automatic repeat request (HARQ) acknowledgement (ACK). The configuration information may indicate a first sequence. The WTRU may be configured to determine a set of sequences to be used in response to the receipt of the one or more downlink signals. The set of sequences may be determined based on the indicated first sequence. The WTRU may be configured to send a second sequence from the set of sequences in the time and frequency resources to indicate HARQ-ACK. The second sequence may be selected based on a number of physical downlink control channel (PDCCH) monitoring occasions associated with the indicated HARQ-ACK.
