1. An information transmission method comprising:

  • obtaining, by a terminal, subframe configuration information of at least two serving cells, and obtaining an HARQ timing relationship corresponding to each serving cell of the at least two serving cells, wherein the subframe configuration information of each serving cell of the at least two serving cells is used to indicate uplink subframes used by the terminal and muted uplink subframes in each serving cell, and/or used to indicate downlink subframes used by the terminal and muted downlink subframes in each serving cell; and

    transmitting, by the terminal according to the HARQ timing relationship corresponding to each serving cell of the at least two serving cells, information with a network side device in the uplink subframes and/or downlink subframes indicated by the subframe configuration information of each serving cell;

    wherein, the at least two serving cells comprise at least one first serving cell, wherein an HARQ timing relationship corresponding to the first serving cell is an HARQ timing relationship corresponding to TDD configuration n, and an uplink and downlink configuration of TDD configuration n is different from an uplink and downlink configuration of the first serving cell;

    wherein according to the HARQ timing relationship corresponding to TDD configuration n, an uplink ACK/NACK corresponding to at least one downlink subframe of the first serving cell is configured to be transmitted in a corresponding uplink subframe, and/or, according to the HARQ timing relationship corresponding to TDD configuration n, a downlink ACK/NACK corresponding to a PUSCH of at least one uplink subframe of the first serving cell is configured to be transmitted in a corresponding downlink subframe; and

    wherein a TDD system has N uplink and downlink configurations, wherein n is a natural number that is less than or equal to N−

    1 and greater than or equal to 0, and N is a natural number that is greater than or equal to 1;

    or, a timing relationship of a first downlink subframe set of the first serving cell is an HARQ timing relationship of FDD, and a timing relationship of a second downlink subframe set of the first serving cell is an HARQ timing relationship of TDD.
