CARRIER MODULATION IN COMMUNICATIONS

摘要

A method disclosed comprising selecting (201), in a network node, a predefined time unit PTU defining a maximum resource allocation unit in time in downlink. The network node schedules (202) one or more terminal devices such that a scheduling periodicity is one predefined time unit PTU. Based on the scheduling, the network node causes (205) transmission of one or more messages to a terminal device by using a single carrier operation mode.
