Collision avoidance adaptation for autonomous transmission systems

A method in a network node, comprising:

• determining information related to a signal transmission configuration for autonomous uplink transmission by a wireless device, the information comprising:
• a set of pre-allocated resources for use by the wireless device in performing autonomous uplink transmission on at least one secondary cell established between the network node and the wireless device;
• a periodicity associated with the set of pre-allocated resources;
• and
• information about one or more subframes that should be avoided by the wireless device when performing autonomous uplink transmission;
• and
• configuring the wireless device to perform autonomous uplink transmission according to the determined information related to the signal transmission configuration.
