A mobile communication uplink information transmission method and system are provided, to solve a problem that when a terminal device allocates uplink control information and an uplink shared channel on a semi-statically configured physical uplink shared channel, transmission performance of the uplink shared channel is affected by a quantity of resources occupied by the uplink control information. The method is used for a terminal device to send uplink information and a network device to receive uplink information, and the terminal device receives grant-free resource configuration information, and determines a first resource used to allocate a physical uplink shared channel. The terminal device further determines a third resource used to allocate an uplink shared channel. The third resource is a part of the first resource and does not intersect with the second resource, or the second resource is empty. The present invention further provides a system used for the method.

When arranging a reference signal generated by a pseudorandom number on specified time and frequency, an information processing unit (101) determines whether or not to arrange a 1 OFDM symbol or 2 OFDM symbols including a reference signal at a position determined in each slot, and determines whether or not to additionally arrange an OFDM symbol including a reference signal in the same slot. A multiplexing unit (108) performs multiplexing of a reference signal in accordance with the determination by the information processing unit (101).
