Abstract: A network node (120) and method therein for performing multi-channel access procedures in a License-Assisted Access, LAA, cell in a wireless communication network are disclosed. The network node selects one carrier as a master carrier and starts a Listen Before Talk, LBT, channel sensing for all carriers at a same or different point in time.
