Information transmission method, user equipment, and network device

The invention discloses an information transmission method, a user equipment, and a network device. The method comprises: receiving control signaling sent by a network device, the control signaling being used for instructing a user equipment to send band information of an uplink signal; determining, according to at least one of receiving time information for receiving the control signaling, sending time information of the uplink signal, and the band information, a first group of parameters in at least two groups of parameters used for generating a reference signal; generating a first reference signal according to the first group of parameters; and sending the uplink signal comprising the first reference signal to the network device according to the control signaling. In the information transmission method, the user equipment, and the network device in embodiments of the present invention, the parameters used for generating the reference signal are determined based on at least one of the receiving time information, the sending time information, and the band information, so that the system signaling overhead can be reduced, and the system performance can be improved.
