Resource indication method, apparatus, and system
A communication operation carried out by a base station is described herein. The operation includes generating first indication information. The first indication information indicates configuration information of a first resource. The operation further includes generating second indication information. The second indication information indicates a relationship between a second resource and the first resource to a terminal. The operation further includes sending the first indication information and the second indication information, so that the terminal determines its own receiving resource or sending resource. When the base station indicates the receiving resource or the sending resource of the terminal resource indication overheads can be reduced.
