Abstract: A method of processing a signal received over a wireless link may utilize sharing of Modulation and Coding Scheme (MCS) and Transport Block Size (TBS) data. At least one parameter is obtained including a sub-carrier spacing of a transport format. A modulation order and a transport block size may be detected, based on the at least one parameter. The signal received over the wireless link is then processed, based on the detected modulation order and the transport block size. An apparatus may perform the embodiments of the method to process the received signal.
