METHOD AND APPARATUS FOR TRANSMISSION TIMING USING TIMING ADVANCE IN FULL-DUPLEX SYSTEMS

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.
