Multicast-based wireless communication method, terminal device, and base station

A terminal device, comprising:

• a memory that stores program code;
• a processor coupled to the processor;
• wherein the processor is configured to execute the stored program code to perform the steps of:
• receiving downlink control information (DCI) transmitted by a base station, wherein the DCI is used to schedule a current multicast traffic channel (MTCH), the DCI comprises indication information, and the indication information is used to indicate that configuration information of the current MTCH is modified in a next modification period (MP) or a current MP;
• and
• obtaining modified configuration information of the current MTCH according to the indication information.

A base station, comprising:

• a processor and a memory coupled to the processor;
• wherein the processor is configured to execute store program codes to perform:
• generating downlink control information (DCI), wherein the DCI is used to schedule a first multicast traffic channel (MTCH), the DCI comprises indication information, and the indication information is used to indicate that configuration information of the first MTCH is modified in a next modification period (MP) or a current MP;
• and
• transmitting the DCI to a terminal device.
