Communication method and apparatus

A communication method, comprising:

• detecting first indication information from a first network device in a first time unit, wherein the first indication information indicates a first downlink resource;
• detecting third indication information from the first network device, wherein the third indication information indicates that content indicated by a first field in the first indication information is the same as content indicated by the first field in second indication information, wherein the second indication information indicates a second downlink resource, and wherein the first downlink resource and the second downlink resource are used to carry downlink data;
• and
• performing quick decoding on the first indication information and the second indication information based on the first field, or checks correctness of decoding the first indication information and the second indication information.

An apparatus, comprising:

• one or more processors;
• and
• a non-transitory memory storing computer instructions that, when executed by the one or more processors, cause the apparatus to perform operations comprising:
• generating first indication information, wherein the first indication information indicates a first downlink resource;
• sending third indication information, wherein the third indication information indicates that content indicated by a first field in the first indication information is the same as content indicated by the first field in a second indication information, wherein the second indication information indicates a second downlink resource, and wherein the first downlink resource and the second downlink resource are used to carry downlink data;
• and
• sending the first indication information in a first time unit to a terminal device.
