Abstract:
In accordance with some embodiments, a method may include selecting, by a user equipment, at least one random access occasion associated with at least one contention based random access resource and at least one random access occasion associated with at least one contention free random access resource. The method may further include detecting, by the user equipment, a predetermined number of listen before talk failures associated with one or more of the at least one random access occasion associated with at least one contention free random access resource. The method may further include transmitting, by the user equipment, in response to detecting a predetermined number of listen before talk failures, according to the selected at least one random access occasion associated with at least one contention based random access resource.
