Abstract: Methods are disclosed for a wireless transmit receive unit (WRTU)-side full duplex (FD) transmission and reception to determine and report hypothetic/candidate UL self-interference based on a DL channel measurement with simultaneous UL transmission and a set of (pre)configured UL transmission hypotheses. In one example, methods are disclosed for WTRU measurement and reporting self-interference cancellation (SIC) ratio(s) and/or SIC ratio offset(s) corresponding to a default/reference configuration and a configuration of hypothetical candidate UL reference signal parameters for simultaneous UL transmission. In one example, methods are disclosed for WTRU measurement of actual channel state information (CSI) of DL RS with simultaneous UL transmission and determination of hypothetical/candidate CSI based on the actual CSI and SIC ratio offset corresponding to the difference in TX parameters between the actual and hypothetical simultaneous UL transmissions, e.g.

Abstract: Methods for uplink (UL) sounding reference signal (SRS) transmissions on subband-overlapping full-duplex (SBFD) symbols are provided herein. A method performed by a wireless transmit/receive unit (WTRU) includes receiving configuration information indicating one or more SRS resource sets and a plurality of transmission configuration indication (TCI) states, and receiving second configuration information indicating one or more TCI codepoints. One of the TCI codepoints is associated with a first and a second TCI state. The WTRU determines the TCI codepoint is to be applied, and that the first and the second TCI state are associated with a non-SBFD mode of operation and an SFBD mode of operation, respectively. The WTRU transmits an SRS using a transmission occasion of one of the SRS resource sets and, based on whether non-SBFD or SBFD operation is used, uses the first or the second TCI state.

Abstract: A sidelink (SL) wireless transmit and receive unit (WTRU) may be configured establish a unicast link with a peer WTRU allowing use of a plurality of SL carriers and transmits data, on at least a first SL carrier to the peer WTRU. The WTRU determines a carrier-specific SL radio link failure (RLF) of the first SL carrier based on a number of detected consecutive hybrid automatic repeat request (HARQ) discontinuous transmissions (DTXs) exceeding a threshold HARQ DTX count and performs a SL carrier reselection procedure to select a second SL carrier, excluding SL carriers determined with carrier-specific SL RLF. The WTRU transmits, to the peer WTRU on one of the plurality of SL carriers without carrier-specific SL RLF, an indication of the carrier-specific RLF of the first SL carrier. If no SL available SL carrier remains, the WTRU releases the unicast link with the peer WTRU. Additional embodiments are disclosed.

Abstract: Systems, methods, and instrumentalities are described herein for enhanced channel access. Resources may be configured to enable load-based equipment (LBE) access in an otherwise frame-based equipment (FBE) network. LBE access may be, for example, LBT category four (Cat 4). A wireless transmit/receive unit (WTRU) may determine whether an LBE resource is valid based on current channel occupancy. A WTRU may use an LBE resource as a function of a transmission priority (e.g., priority of the content of the transmission, for example a first PUSCH transmission may be associated with a first priority and a second PUSCH transmission may be associated with a second priority), transmission type (e.g., whether the transmission is for PUSCH or PUCCH, for DG-PUSCH or CG-PUSCH, for data or CSI or HARQ-ACK, etc.), requirement(s), and/or grant. A WTRU may use an LBE resource, for example, as a fallback resource.
