Method and apparatus for indicating slot format of an unlicensed cell in a wireless communication system

A User Equipment (UE), comprising:

• a processor;
• and
• a memory operatively coupled to the processor wherein the processor is configured to execute a program code to:
• perform transmission and/or reception in a serving cell, wherein the serving cell is in unlicensed spectrum;
• be configured to receive slot format indication (SFI) on one or more periodic SFI monitoring occasions, wherein the one or more periodic SFI monitoring occasions are (pre-)configured by a network;
• and
• monitor and/or detect a SFI-related signal on a first occasion in response to receiving and/or detecting a channel indicator, during a time duration defined at least in part by a channel occupancy time (COT) of the network, wherein the first occasion is not one of the one or more (pre-)configured periodic SFI monitoring occasions, wherein the first occasion is configured by a first configuration which is different from a second configuration for the one or more periodic SFI monitoring occasions, wherein the first configuration configures a first periodicity and a first slot offset for the first occasion, and wherein the first periodicity and the first slot offset for the first occasion is different from a second periodicity and a second slot offset associated with the one or more periodic SFI monitoring occasions.
