1. A method performed by a wireless communication device, the method comprising:
receiving, from a network node, a channel access mode indication, the channel access mode indication being an indication of whether the wireless communication device is to operate in a Frame-Based Equipment (FBE) channel access mode or a Load-Based Equipment (LBE) channel access mode;
determining a channel access mode in which to operate based on the channel access mode indication, wherein the determined channel access mode is the FBE channel access mode, and operating in the determined channel access mode comprises operating as a responding node by:
determining whether a Downlink (DL) transmission is received during a particular Fixed Frame Period (FFP); and
upon determining that the DL transmission is received during the particular FFP, transmitting an Uplink (UL) transmission in the particular FFP; and
operating in the determined channel access mode.
