A method for information transmission in a Machine Type Communication MTC system, comprising: acquiring a candidate subframe set and a candidate narrowband set for transmitting first information; determining, in the candidate subframe set and the candidate narrowband set, a subframe set and a narrowband for transmitting the first information according to a Physical Cell Identity PCID; and sending or receiving the first information on the subframe set and the narrowband; the method being further characterised in that: wherein determining the subframe set and the narrowband for transmitting the first information according to the PCID comprises: dividing the candidate subframe set for transmitting the first information into N subframe subsets, determining a belonging group of the PCID according to a first rule, acquiring a group number n of the belonging group, and determining a subframe subset whose number is the same as the group number n as the subframe set for transmitting the first information; wherein, the N is a positive integer, and the n is an integer less than the N; acquiring the number M of the narrowbands comprised in the candidate narrowband set, determining the belonging group of the PCID according to a second rule, acquiring a group number m of the belonging group, and determining a narrowband whose number is the same as the group number m as the narrowband for transmitting the first information; wherein, the M is a positive integer, and the m is an integer less than the M. acquiring a candidate subframe set and a candidate narrowband set for transmitting first information; determining, in the candidate subframe set and the candidate narrowband set, a subframe set and a narrowband for transmitting the first information according to a Physical Cell Identity PCID; and sending or receiving the first information on the subframe set and the narrowband; the method being further characterised in that: wherein determining the subframe set and the narrowband for transmitting the first information according to the PCID comprises: dividing the candidate subframe set for transmitting the first information into N subframe subsets, determining a belonging group of the PCID according to a first rule, acquiring a group number n of the belonging group, and determining a subframe subset whose number is the same as the group number n as the subframe set for transmitting the first information; wherein, the N is a positive integer, and the n is an integer less than the N; acquiring the number M of the narrowbands comprised in the candidate narrowband set, determining the belonging group of the PCID according to a second rule, acquiring a group number m of the belonging group, and determining a narrowband whose number is the same as the group number m as the narrowband for transmitting the first information; wherein, the M is a positive integer, and the m is an integer less than the M. dividing the candidate subframe set for transmitting the first information into N subframe subsets, determining a belonging group of the PCID according to a first rule, acquiring a group number n of the belonging group, and determining a subframe subset whose number is the same as the group number n as the subframe set for transmitting the first information; wherein, the N is a positive integer, and the n is an integer less than the N; acquiring the number M of the narrowbands comprised in the candidate narrowband set, determining the belonging group of the PCID according to a second rule, acquiring a group number m of the belonging group, and determining a narrowband whose number is the same as the group number m as the narrowband for transmitting the first information; wherein, the M is a positive integer, and the m is an integer less than the M.
