Method and apparatus for slot format indication for an ending slot in unlicensed spectrum in a wireless communication system

A method for a UE (User Equipment), comprising:

• the UE is configured by a network node to receive and/or monitor a signal within a channel occupancy time, wherein the signal indicates information of one or multiple TTIs (Transmission Time Interval) of a serving cell;
• the UE derives state or functionality of one or more symbol(s) in the one or multiple TTIs based on the information, wherein the information indicates a symbol in the one or multiple TTIs to be any of “downlink”, “uplink”, “flexible”, or “blank”;
• the UE considers or interprets a TTI, among the one or multiple TTIs, as an ending TTI of the channel occupancy time, wherein the TTI comprises (the last set of) consecutive symbols indicated as “blank” and at least one symbol not indicated as “blank” before the (last set of) consecutive symbols indicated as “blank”;
• and
• the UE considers or interprets a symbol, among the one or more symbol(s), as an ending symbol of the channel occupancy time, wherein the symbol is the last symbol not indicated as “blank” in the ending TTI.

A method for a UE (User Equipment), comprising:

• the UE is configured by a network node to receive and/or monitor an indication in or for a serving cell;
• the UE derives (information of) an ending TTI (Transmission Time Interval) of a channel occupancy time at least based on the indication;
• the UE derives (information of) a first symbol at least based on the indication, wherein the first symbol is within the ending TTI and considered or determined as an ending symbol of the channel occupancy time;
• the UE receives a DCI (Downlink Control Information) scheduling a resource for a transmission or reception in the serving cell, wherein a second symbol is the last symbol of the scheduled resource;
• if the second symbol is later than or located after the first symbol, the UE (re-)considers or (re-)determines the second symbol is the ending symbol of the channel occupancy time;
• and
• the UE performs the transmission or reception on the scheduled resource until (the end of) the ending symbol or the second symbol.
