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.

Dependent claims

A method of processing a signal received over a wireless link, the method comprising:

obtaining, by a user equipment, downlink control information;
extracting a field corresponding to an adjustment indicator, the field including a plurality of bits indicating a change amount of a modulation order, and/or a plurality of bits indicating a change amount of a transport block size index from the downlink control information;
identifying the adjustment indicator from the extracted field;
updating at least one of the modulation order and the transport block size index by reflecting the respective change amount to the at least one of the modulation order and the transport block size index in response to the identified adjustment indicator;
and
processing the received signal, based on at least one of the updated modulation order and the updated transport block size index.
