1. A method performed by a network device for indicating a Transport Block Size, TBS, the method comprising:
transmitting Downlink Control Information, DCI, to a terminal device, the DCI containing information from which a TBS index is derivable, wherein the TBS 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, wherein, 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, and wherein the TBSs usable with 16-QAM are associated with different ranges of TBS indices depending on whether the terminal device operates in a stand-alone, guard-band, or in-band deployment mode.
