Abstract: Apparatuses and methods for uplink transmission in full-duplex systems. A method includes receiving first information for first parameters that include a first time-domain resource allocation (TDRA) table associated with a first subset of slots from a set of slots on a cell and second information for second parameters that include a second TDRA table associated with a second subset of slots from the set of slots on the cell. The method further includes determining a first TDRA entry from the first TDRA table and a second TDRA entry from the second TDRA table and transmitting a first repetition of a physical uplink shared channel (PUSCH) in a first slot from the first subset of slots on the cell based on the first TDRA entry and a second repetition of the PUSCH in a second slot from the second subset of slots on the cell based on the second TDRA entry.

Abstract: Apparatuses and methods for transmission timing in full-duplex systems. A method for receiving a downlink (DL) signal or channel associated with a reception timing procedure includes receiving first information for a receive timing adjustment value and second information for a condition. The method further includes determining a DL reference timing and whether the condition is valid for reception in a slot. The method further includes receiving the DL signal or channel in the slot based on the receive timing adjustment value and the DL reference timing when the condition is valid and the DL reference timing when the condition is not valid.

Abstract: Apparatuses and methods for random access procedure for full-duplex operation. A method for a user equipment includes receiving first information for first parameters of a first random-access channel (RACH) configuration associated with a first subset of slots from a set of slots on a cell and second information for second parameters of a second RACH configuration associated with a second subset of slots from the set of slots on the cell. The method further includes determining a RACH configuration, among the first and second RACH configurations, for a physical random-access channel (PRACH) transmission in a slot on the cell based on whether the slot is from the first subset of slots or the second subset of slots and transmitting the PRACH in the slot on the cell based on the determined RACH configuration.

Abstract: Apparatuses and methods for monitoring indications for physical downlink control channels (PDCCHs) in full-duplex (FD) systems. A method includes receiving a set of discontinuous reception (DRX) parameters associated with a subband full-duplex (SBFD) configuration and receiving a first PDCCH that provides a downlink control information (DCI) format. The DCI format includes a wake-up indication field enabling or disabling receptions of a second PDCCH, in a DRX on-period, for a symbol or a subband type. The method further includes selecting, based on the wake-up indication field, the symbol or the subband type for receptions of the second PDCCH and receiving, based on (i) the selected symbol or subband type and (ii) the set of DRX parameters, the second PDCCH at a first occasion in a DRX on-duration or during a DRX active time. The first occasion is after reception of the first PDCCH and before an end duration.

Abstract: A method of operating a user equipment includes receiving first information for a first candidate subband full-duplex (SBFD) configuration associated with a first L1/L2-Triggered Mobility (LTM) candidate cell or reference configuration, receiving second information for a second candidate SBFD configuration associated with a second LTM candidate cell or reference configuration, and determining a value of an SBFD indicator. The method further includes selecting an SBFD configuration of an LTM candidate cell based on the first information when the value is associated with the first LTM candidate cell or reference configuration or the second information when the value is associated with the second LTM candidate cell or reference configuration; and receiving a downlink signal based on the SBFD configuration of the LTM candidate cell. The value of the SBFD indicator is from a set of identifier values associated with a set of transmit-receive points.

Abstract: Apparatuses and methods for prioritization of uplink transmissions by repeaters. A method for a network-controlled repeater (NCR) includes receiving, by an NCR mobile termination (NCR-MT) entity, first information for a first uplink transmission by the NCR-MT entity and second information for a second uplink transmission by an NCR forward (NCR-Fwd) entity that overlap in one or more symbols. The method further includes identifying a power limit for simultaneous transmission by the NCR-MT and NCR-Fwd, determining first and second powers for the first and second uplink transmissions, respectively, and when a sum of the first and second powers in the one or more symbols exceeds the power limit, third and fourth powers for the first and second uplink transmissions, respectively, that do not exceed the power limit. The method further includes transmitting, in the one or more symbols, the first and second uplink transmissions with the third and fourth powers, respectively.

Abstract: Apparatuses and methods for channel quality reporting for full duplex systems. A method performed by a user equipment (UE) includes receiving information about a channel state information (CSI) report associated with N>1 hypotheses. A first hypothesis of the N hypotheses is associated with a channel quality indicator (CQI) for subband full duplex (SBFD) slots or symbols. A second hypothesis of the N hypotheses is associated with a CQI for non-SBFD slots or symbols. The method further includes identifying whether a slot or symbol is SBFD or non-SBFD; determining, based on the identification, a CQI using the first or second hypotheses; and transmitting the CSI report, including the determined CQI.

Abstract: Radio link monitoring in full-duplex systems. A method includes receiving first information for a first set of radio link monitoring (RLM) reference signals (RSs) corresponding to a first subset of slots on a cell and receiving second information for a second set of RLM RSS corresponding to a second subset of slots on the cell. The method further includes determining a radio link failure for the first subset of slots when a reception quality of any of the first set of RLM RSs is below a reception quality threshold for a time period and determining a radio link failure for the second subset of slots when a reception quality of any of the second set of RLM RSs is below a reception quality threshold for a time period. The second subset of slots includes time-domain resources indicated for simultaneous transmission and reception and the first subset of slots do not.

Abstract: Apparatuses and methods for dormancy indication in full-duplex (FD) systems. A method for a user equipment (UE) to receive physical downlink control channels (PDCCHs) includes receiving a set of carrier aggregation (CA) parameters for a serving cell associated with a subband full-duplex (SBFD) configuration on the serving cell and receiving a first PDCCH that provides a downlink control information (DCI) format. The DCI format includes a secondary cell (SCell) dormancy indication enabling or disabling receptions of a second PDCCH, in a downlink (DL) bandwidth part (BWP) associated with a group of configured SCells, for a symbol or a subband type. The method further includes selecting, based on the SCell dormancy indication, the symbol or the subband type for receptions of the second PDCCHs on an SCell in the group of configured SCells and receiving the second PDCCH in the BWP of the SCell at a first occasion.

Abstract: Methods and apparatuses for beam indication for full duplex. A method of operating a user equipment (UE) includes receiving first and second information that includes first and second transmission configuration indicator (TCI) state configurations associated with first and second subsets of slots or symbols, respectively, on a cell and receiving a downlink control information (DCI) format that includes a first or second TCI state code point from the first or second TCI state configuration. The method further includes determining, based on whether a slot or symbol is from the first or second subset, the first or second TCI state code point and receiving, based on the determination, a shared data or control channel or signal using the first or second TCI state code point. The first subset does not include time-domain resources indicated for simultaneous transmission and reception on the cell and the second subset does.
