## 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.
