Methods and apparatuses for transmission timing using a transmission timing configuration in full-duplex systems

A user equipment (UE) comprising:

• a transceiver configured to receive:
• 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 downlink (DL) and/or uplink (UL) transmission or reception conditions;
• and
• a processor operably coupled to the transceiver, the processor configured to determine a value corresponding to the DL and/or UL transmission or reception conditions for transmission in a slot from the second subset of slots,
• wherein the transceiver is further configured to transmit an UL signal or channel in the slot based on:
• the first transmission timing configuration based on a first state of the value corresponding to the DL and/or UL transmission or reception conditions, and
• the second transmission timing configuration based on a second state of the value corresponding to the DL and/or UL transmission or reception conditions.

A base station (BS) comprising:

• a transceiver configured to transmit:
• 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 downlink (DL) and/or uplink (UL) transmission or reception conditions;
• and
• a processor operably coupled to the transceiver, the processor configured to determine a value corresponding to the DL and/or UL transmission or reception conditions for reception in a slot from the second subset of slots,
• wherein the transceiver is further configured to receive an UL signal or channel in the slot based on:
• the first transmission timing configuration based on a first state of the value corresponding to the DL and/or UL transmission or reception conditions, and
• the second transmission timing configuration based on a second state of the value corresponding to the DL and/or UL transmission or reception conditions.
