Method, device and system for indicating resources

The invention discloses a method, a device and a system for indicating resources. The method comprises the following steps: user equipment (UE) monitors a compressed physical downlink control channel (PDCCH) obtained by compressed corresponding downlink control information (DCI); the UE resolves the DCI of the PDCCH to obtain a resource number; and the UE utilizes the preset corresponding relation between resource numbers and resource positions to confirm the corresponding resource position of the obtained resource number. The device comprises a distribution unit, a first notification unit and a channel-compressing unit for a substation and comprises a monitoring unit, a resolving unit and a confirmation unit for a terminal. The invention saves command control equipment (CCE) resources and avoids causing influence on other equipment in a section.
