Abstract

The present disclosure provides a method () in a network device. The method () includes: transmitting () Downlink Control Information, DCI, to a terminal device, the DCI containing information from which a TBS index is derivable. The BS index is usable to determine a TBS from a set of TBSs including TBSs usable with Quadrature Phase Shift Keying, QPSK, and TBSs usable with 16-Quadrature Amplitude Modulation, 16-QAM. When the DCI is for a Narrowband Physical Downlink Shared Channel, NPDSCH, the TBSs usable with 16-QAM are determinable by the terminal device based on a deployment mode.
