Title: RANDOM ACCESS METHOD FOR MULTIPLE NUMEROLOGY OPERATION
Abstract:
The present disclosure introduces methods and apparatus for configuring or preconfiguring random access procedures when there are multiple configurable numerologies for one carrier. In some embodiments, the random access numerology of the wireless device is configured using the system information block. In other embodiments, the random access numerology used by the wireless device is determined implicitly based on the detection of one or more synchronization signals.
