Indication information transmission method, apparatus, and system

An apparatus, comprising:

• one or more processors configured to:
• receive first information, wherein the first information comprises range indication information or direction indication information;
• and
• determine, based on the first information, whether the apparatus is capable of providing auxiliary resource information for a first terminal apparatus, wherein the auxiliary resource information is for determining a sending resource of the first terminal apparatus, wherein
• in response to the apparatus being capable of providing the auxiliary resource information for the first terminal apparatus, send first indication information to the first terminal apparatus, wherein the first indication information comprises the auxiliary resource information;
• or
• in response to the apparatus being incapable of providing the auxiliary resource information for the first terminal apparatus, send second indication information to the first terminal apparatus, wherein the second indication information indicates that the apparatus is incapable of providing the auxiliary resource information for the first terminal apparatus.

An apparatus, comprising:

• one or more processors configured to:
• send first information to at least one second terminal apparatus, wherein the first information comprises range indication information or direction indication information, and the first information is used by the at least one second terminal apparatus to determine whether the at least one second terminal apparatus is capable of providing auxiliary resource information for the apparatus;
• and
• receive first indication information or second indication information from the second terminal apparatus, wherein the first indication information comprises the auxiliary resource information, the auxiliary resource information is for determining a sending resource, and the second indication information indicates that the second terminal apparatus is incapable of providing the auxiliary resource information for the apparatus.
