9. A second User Equipment (UE), comprising:
a control circuit;
a processor installed in the control circuit; and
a memory installed in the control circuit and operatively coupled to the processor, wherein the processor is configured to execute a program code stored in the memory to perform operations, the operations comprising:
receiving a first sidelink transmission from a first UE, wherein the first sidelink transmission comprises channel occupancy time (COT) sharing information;
based on the COT sharing information, determining whether or not a second sidelink transmission, to be performed by the second UE, is within a COT initiated by the first UE;
in response to the second sidelink transmission being within the COT initiated by the first UE, prioritizing at least one of data, one or more logical channels (LCHs) or one or more Medium Access Control Control Elements (MAC CEs) associated with the first UE for the second sidelink transmission, wherein the prioritizing is used for selecting a destination, associated with the first UE, for the second sidelink transmission, wherein:
the destination comprises at least one of:
a destination identifier (ID) of the first UE;
a groupcast destination ID of a group comprising the first UE; or
a broadcast destination ID; and
the second sidelink transmission comprises data with a channel access priority class (CAPC) value that is the same or lower than a specific CAPC value which is included in the COT sharing information transmitted by the first UE; and
in response to performing successful listen before talk (LBT), transmitting the second sidelink transmission to the selected destination associated with the first UE.
