a value indicating used resources of the configured grant
a ratio of used resources of the configured grant to a total of the configured grant;
a percentage of used resources of the configured grant;
a collision ratio of the configured grant;
a time period considered for the utilization information; or
a number of wireless devices activated to use the configured grant.
13. The base station distributed unit of claim 11 , wherein the instructions further cause the base station distributed unit to:
receive, from the base station central unit, a third message based on the utilization information, wherein the third message comprises second configuration parameters of the configured grant for a second wireless device, the second configuration parameters comprising:
