An information transmission method, performed by an information transmission apparatus, the method comprising: determining a transmission resource for a physical signal or a physical channel corresponding to a scheduling request; and transmitting the physical signal or the physical channel on the transmission resource, wherein the scheduling request is used for requesting a resource allocation for data transmission; wherein the determining the transmission resource of the physical signal or the physical channel corresponding to the scheduling request comprises: determining whether a collision exists between a transmission resource of an ACK/NACK and a configured transmission resource of the physical signal or the physical channel; and in a case where the collision exists, determining the transmission resource of the physical signal or the physical channel according to a collision resolution strategy; the method being characterized in that: the determining the transmission resource of the physical signal or the physical channel according to the collision resolution strategy comprises: in a case where a size of the configured transmission resource of the physical signal or the physical channel is same as that of the transmission resource of the ACK/NACK signal, a time domain position of the transmission resource of the physical signal or the physical channel of the request is aligned with a time domain position of the transmission resource of the ACK/NACK signal, and downlink data is received, determining the transmission resource of the physical signal or the physical channel to be the transmission resource of the ACK/NACK signal; and wherein the transmitting the physical signal or the physical channel on the transmission resource comprises: simultaneously carrying the ACK/NACK signal and the physical signal or the physical channel on the transmission resource of the ACK/NACK signal corresponding to the downlink data; and modulating the ACK/NACK signal and the physical signal or the physical channel needed to be transmitted by using quadrature phase shift keying, QPSK, or Π/4-QPSK. determining a transmission resource for a physical signal or a physical channel corresponding to a scheduling request;
