Question: In 3GPP-compliant networks, when a gNodeB (gNB) employs Type 2C Downlink (DL) channel access procedures for transmitting a DL transmission, what characterizes its approach to channel sensing before initiating the transmission?
Option 1: The gNB always senses the channel for a fixed duration before transmitting.
Option 2: The gNB does not sense the channel before transmission of the DL transmission.
Option 3: The gNB senses the channel only if the previous transmission was unsuccessful.
Option 4: The gNB performs periodic channel sensing, but not necessarily before each DL transmission.
Explanation: This is correct because, according to Type 2C DL channel access procedures in shared spectrum environments, the gNodeB (gNB) does not perform channel sensing immediately before transmitting a downlink signal, impacting how the network manages interference and allocates resources in shared spectrum scenarios.
