Abstract:
Method and devices are provided for a channel access mechanism for accessing a network on a random access channel (RACH). Methods involve defining a listen-before-talk (LBT) category to be used as part of a contention based procedure and how a contention window that is part of the LBT can be dynamically adjusted.
