Device and Method Handling Transmission in Unlicensed Band

A network for handling a transmission, comprising:

• a storage unit, for storing instructions of:
• performing a first channel access procedure on a channel of an unlicensed band not based on any channel access priority class for a first transmission on the channel, wherein the first transmission comprises at least one of a physical downlink (DL) control channel (PDCCH) order or an uplink (UL) grant;
• and
• performing a second channel access procedure on the channel based on a channel access priority class for a second transmission on the channel, wherein the second transmission comprises a physical DL shared channel (PDSCH) transmission;
• and
• a processing circuit, coupled to the storage unit, configured to execute the instructions stored in the storage unit.
