Abstract: Embodiments of the present disclosure relate to downlink control and data channel configuration. A method comprises: determining, at a first device, a transmission scheme of control information for a second device based on at least one multicast and broadcast service related criterion, the control information related to scheduling multicast service traffic to the second device; transmitting, to the second device, configuration information for causing the second device to obtain the control information; and transmitting, to the second device and based on the determined transmission scheme, the control information on a control channel between the first device and the second device. In this way, the correlation between the scheduling mechanism of multicast traffic on the downlink data channel and the transmission mechanism of control information on the downlink control channel can be decoupled, resulting in a flexible and dynamic downlink channel configuration and an increased radio resource efficiency.
