1. A second device comprising:
at least one processor; and
at least one memory including computer program code;
the at least one memory and the computer program code configured to, with the at least one processor, cause the second device to:
receive assistance information from a first device, the assistance information enabling the second device to identify, within a bandwidth part configured for the second device, a frequency domain resource allocated for multicast traffic; and
determine the frequency domain resource from downlink control information based on the assistance information, the downlink control information received from the first device and comprising a field indicating the frequency domain resource,
wherein the assistance information comprises at least:
a parameter for adaptation of a size of a bandwidth part of the multicast traffic relative to a size of the bandwidth part configured for the second device, and
wherein the second device is caused to determine the frequency domain resource by:
in accordance with a determination that the field comprises index information of a starting resource block and the number of resource blocks, obtaining further index information based on the index information and an offset;
determining a resource indicator value based on the further index information, the parameter and the number of resource blocks; and
determining the frequency domain resource based on the resource indicator value.
