A method for resource indication, comprising: receiving, by a terminal device, first configuration information from a network device, the first configuration information being configured to configure N transmission resources, N≥2 and N being an integer, wherein the first configuration information is radio resource control, RRC, signaling, receiving, by the terminal device, first indication information from the network device, wherein the first indication information is downlink control information, DCI; characterized in that, if the first indication information indicates a transmission resource configured for the terminal device to detect a physical downlink control channel, PDCCH, detecting, by the terminal device, the PDCCH on the transmission resource indicated by the first indication information; and/or, if the first indication information indicates a transmission resource not configured for the terminal device to detect a PDCCH, not detecting the PDCCH on the transmission resource indicated by the first indication information, wherein the first indication information comprises indication information of M1 transmission resources, M1 being a positive integer and 1≤ M1 ≤N, and a first transmission resource is one of the M1 transmission resources; in case of the first transmission resource being the transmission resource configured for the terminal device to detect a PDCCH before the first indication information is received, not detecting the PDCCH on the first transmission resource after the first indication information is received; and/or, in case of the first transmission resource being not the transmission resource configured for the terminal device to detect a PDCCH before the first indication information is received, detecting the PDCCH on the first transmission resource after the first indication information is received, wherein the transmission resource is a search space, SS. receiving, by a terminal device, first configuration information from a network device, the first configuration information being configured to configure N transmission resources, N≥2 and N being an integer, wherein the first configuration information is radio resource control, RRC, signaling, receiving, by the terminal device, first indication information from the network device, wherein the first indication information is downlink control information, DCI; characterized in that, if the first indication information indicates a transmission resource configured for the terminal device to detect a physical downlink control channel, PDCCH, detecting, by the terminal device, the PDCCH on the transmission resource indicated by the first indication information; and/or, if the first indication information indicates a transmission resource not configured for the terminal device to detect a PDCCH, not detecting the PDCCH on the transmission resource indicated by the first indication information, wherein the first indication information comprises indication information of M1 transmission resources, M1 being a positive integer and 1≤ M1 ≤N, and a first transmission resource is one of the M1 transmission resources; in case of the first transmission resource being the transmission resource configured for the terminal device to detect a PDCCH before the first indication information is received, not detecting the PDCCH on the first transmission resource after the first indication information is received; and/or, in case of the first transmission resource being not the transmission resource configured for the terminal device to detect a PDCCH before the first indication information is received, detecting the PDCCH on the first transmission resource after the first indication information is received, in case of the first transmission resource being the transmission resource configured for the terminal device to detect a PDCCH before the first indication information is received, not detecting the PDCCH on the first transmission resource after the first indication information is received; and/or, in case of the first transmission resource being not the transmission resource configured for the terminal device to detect a PDCCH before the first indication information is received, detecting the PDCCH on the first transmission resource after the first indication information is received, wherein the transmission resource is a search space, SS.
