Abstract: Methods and apparatuses for resource association and link recovery for repeaters in a wireless communication system. A method for a network-controlled repeater (NCR) includes receiving first information for time-domain resources and for corresponding beams for an access link and receiving or transmitting radio frequency (RF) signals on the access link using the beams over the corresponding time-domain resources prior to a link failure event. The method further includes determining the link failure event on a control link (C-link) and performing a link recovery procedure on the C-link. The method further includes suspending receiving or transmitting the RF signals on the access link using the beams over the corresponding time-domain resources during the link recovery procedure.

Abstract: Apparatuses and methods for ON-OFF indication for repeaters. A method for a network-controlled repeater (NCR) includes receiving, by an NCR mobile termination (NCR-MT) entity, first information for a first time-domain resource and for a corresponding first beam for an access link of an NCR forwarding (NCR-Fwd) entity and second information for a second time-domain resource and for a corresponding second beam for the access link of the NCR-Fwd entity. The first time-domain resource overlaps with the second time-domain resource in a first set of symbols. The first time-domain resource is not associated with a priority flag. The second time-domain resources is associated with the priority flag. The method further includes receiving or transmitting a first radio frequency (RF) signal on the access link using the second beam over the first set of symbols.

Abstract: Methods and apparatuses for transmission timing in full-duplex wireless communication systems. A method for transmitting an uplink (UL) signal or channel associated with a transmission timing procedure includes receiving first information for first parameters of a first transmission timing configuration associated with a first subset of slots from a set of slots on a cell, second information for second parameters of a second transmission timing configuration 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 UL signal or channel in the slot based on the first transmission timing configuration when the condition is valid and the second transmission timing configuration when the condition is not valid.

Abstract: Methods and apparatuses for transmission timing using timing advance in full-duplex communication systems. A method for transmitting an uplink (UL) signal or channel associated with a transmission timing procedure includes receiving first information for a first timing advance value associated with a first subset of slots from a set of slots on a cell, second information for a second timing advance value 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 UL signal or channel in the slot based on the first timing advance value when the condition is valid and the second timing advance value when the condition is not valid.

Abstract: Methods and apparatuses for switching duplex mode during random access (RA). A method for operating a user equipment (UE) includes receiving a system information block (SIB) for a cell that provides information for a first configuration of slots for transmissions or receptions in a half-duplex mode and a random access (RA) procedure, determining a UE capability for transmitting and receiving in a full-duplex mode, and determining a transmission of a channel based on the RA procedure and the first configuration of slots. The method further includes transmitting the channel including information of the UE capability using the RA procedure and receiving information for a second configuration of slots for transmissions or receptions in the full-duplex mode.
