Abstract: Apparatuses and methods for beam management for network controlled repeaters (NCRs). A method includes identifying, by an NCR mobile termination (NCR-MT) entity, first information for a first spatial relation associated with a control link (C-link) of the NCR and second information for a second spatial relation associated with a backhaul link (BH-link) of the NCR. The method further includes receiving, by the NCR-MT entity on the NCR C-link, a downlink signal or channel using the first spatial relation and receiving, by an NCR forwarding (NCR-Fwd) entity on the NCR BH-link, a first radio frequency (RF) signal using the second spatial relation. The C-link is associated with a first cell on a first carrier frequency. The BH-link is associated with a second cell on a second carrier frequency. The first and second carrier frequencies are different. The first and second spatial relations are different.

Abstract: Apparatuses and methods for time-division duplex (TDD) for network controlled repeaters (NCRs). A method for an NCR includes identifying, by an NCR mobile termination (NCR-MT) entity, information for first TDD uplink-downlink (UL-DL) patterns for a first cell associated with an NCR control link (C-link) and information for second TDD UL-DL patterns for a second cell associated with an NCR backhaul link (BH-link). The method further includes receiving, by the NCR-MT entity on the NCR C-link, downlink signals or channels on the first cell in first downlink or flexible symbols or slots of the first TDD UL-DL patterns and receiving, by an NCR forwarding (NCR-Fwd) entity on the NCR BH-link, radio frequency signals on the second cell in second downlink or flexible symbols or slots of the second TDD UL-DL patterns. The first and second cells are associated with different carrier frequencies. The first and second TDD UL-DL patterns are different.

Abstract: Apparatuses and methods for transmission timing for repeaters. A method for operating a network-controlled repeater (NCR) includes receiving, by an NCR mobile termination (NCR-MT) entity on an NCR control link, information for a timing value for an NCR forwarding (NCR-Fwd) entity. The method further includes determining, by the NCR, a timing adjustment for an NCR access link based on the timing value and a reference signal (RS). The method further includes receiving, by the NCR-Fwd entity on the NCR access link, a radio frequency (RF) signal based on the timing adjustment.

Abstract: Apparatuses and methods for uplink transmission in full duplex systems. A method for transmitting a physical uplink shared channel (PUSCH) associated with a multi-slot PUSCH transmission procedure includes receiving first information for a first modulation and coding scheme (MCS) indication associated with a first subset of slots from a set of slots on a cell, second information for a second MCS indication associated with a second subset of slots from the set of slots on the cell, and third information for a condition. The method further includes determining whether the condition is valid for transmission in a slot from the second subset of slots and transmitting the PUSCH in a slot associated with the multi-slot PUSCH transmission procedure based on the first MCS indication when the condition is valid and the second MCS indication when the condition is not valid.

The method further includes determining whether the condition is valid for transmission in a slot from the second subset of slots and transmitting a RACH in the slot based on: the first RACH configuration when the condition is valid, and the second RACH configuration when the condition is not valid.

Abstract: Apparatuses and methods for timing information for network controlled repeaters (NCRs). A method for an NCR includes identifying, by an NCR mobile termination (NCR-MT) entity, first information for a first downlink (DL) frame timing associated with first DL receptions on an NCR control link (C-link) and second information for a second DL frame timing associated with second DL receptions on an NCR backhaul link (BH-link). The method further includes receiving, by the NCR-MT entity on the NCR C-link, a DL signal or channel using the first DL frame timing and receiving, by an NCR forwarding (NCR-Fwd) entity on the NCR BH-link, a first radio frequency signal using the second DL frame timing. The NCR C-link is associated with a first cell on a first carrier frequency. The NCR BH-link is associated with a second cell on a second carrier frequency. The first carrier frequency is different from the second carrier frequency.

Abstract: Methods and apparatuses for transmissions and receptions in full-duplex systems. A method of operating a user equipment (UE) includes receiving a first candidate subband full-duplex (SBFD) configuration associated with a first transmission configuration indicator (TCI) state configuration on a cell; receiving a second candidate SBFD configuration associated with a second TCI state configuration on the cell; and identifying a TCI state code point. The method further includes selecting (i) the first candidate SBFD configuration when a value of the TCI state code point is associated with the first TCI state configuration or (ii) the second candidate SBFD configuration when the value of the TCI state code point is associated with the second TCI state configuration and receiving or transmitting a channel or signal based on the selected SBFD configuration.

Abstract: Apparatuses and methods for adaptation of monitoring for physical downlink control channels (PDCCHs) in full-duplex (FD) systems. A method for a user equipment (UE) to receive PDCCHs includes receiving first and second sets of parameters for reception of first and second PDCCHs associated with first and second subset of slots, respectively. The method further includes receiving a first PDCCH from the first PDCCHs that provides a downlink control information (DCI) format that includes a field indicating skipping receptions of the second PDCCHs and skipping, based on the field, receptions of the second PDCCHs in a slot from the second subset of slots at a first occasion that is after reception of the first PDCCH and before an end of a time duration. The second subset of slots includes time-domain resources indicated for simultaneous transmission and reception and the first subset of slots does not.

Abstract: Power headroom reporting in full-duplex systems. A method of operating a user equipment (UE) includes receiving first and second information for first and second sets of parameters for a first and second power headroom reports (PHRs) associated with first and second subsets of slots from a set of slots, respectively, and determining a power for transmission of a physical uplink shared channel (PUSCH) in a slot from the set of slots. The method further includes determining a PHR for the power based on the first set of parameters when the slot is from the first subset of slots or the second set of parameters when the slot is from the second subset of slots and transmitting the PHR based on whether a reporting condition is met. The second subset of slots includes time-domain resources indicated for simultaneous transmission and reception on the cell and the first do not.
