FIELD: wireless communication.
SUBSTANCE: search space is shared, or a number of control channel candidates used in the transmission of information on uplink resource providing is reduced. According to the claimed invention, configuration information is received from a network device by a terminal device, wherein configuration information includes information on the first uplink resource and information on the second uplink resource; and the search space for a downlink control channel is searched by the terminal device to receive information on granting permission.
EFFECT: reduction in blind detections of a terminal device and power consumption of a terminal device.
