Communication method and apparatus

A communication method, applied in a network device or a chip in the network device, comprising:

• sending a first configuration information that indicates a first frequency domain resource for multicast;
• sending a second configuration information that indicates a second frequency domain resource, wherein the second frequency domain resource comprises a CORESET 0 and an initial BWP, and wherein the first frequency domain resource and the second frequency domain resource are configured by using different fields;
• and
• sending first information, wherein the first information is for scheduling a terminal device to send a downlink data channel, the first information comprises frequency domain resource assignment information, wherein the frequency domain resource assignment information indicates a frequency domain resource of the downlink data channel within a range of the first frequency domain resource, and the first information is scrambled by using a G-RNTI.

A communication apparatus, comprising:

• at least one processor connected to a memory, wherein the at least one processor is configured to read and execute a program stored in the memory, to enable the apparatus toa transceiver;
• receive a first configuration information that indicates a first frequency domain resource for multicast;
• receive a second configuration information that indicates a second frequency domain resource, wherein the second frequency domain resource comprises a control-resource set (CORESET) 0 and an initial bandwidth part (BWP), and wherein the first frequency domain resource and the second frequency domain resource are configured by using different fields;
• and
• receive, through the transceiver, a first information, wherein the first information is for scheduling a downlink data channel, the first information comprises frequency domain resource assignment information, wherein the frequency domain resource assignment information indicates a frequency domain resource of the downlink data channel within a range of the first frequency domain resource, and the first information is scrambled by using a group-radio network temporary identifier (G-RNTI).
