There are lots of LENA components, so you'll have to dig a little to find the ones that interest you.
To see all possible log components:
$ NS_LOG="foo" ./waf --run scratch-simulator
("foo" is any token which does not match an existing log component. The failure to match will print the names of all possible components.)
Grep'ing for "lte" (but not "test") yields 36 components that might interest you.
