1. A communication method, comprising:

  • acquiring, by a user equipment (UE), on an anchor carrier, synchronization information to synchronize with a base station, wherein a frequency resource between the UE and the base station comprises N subcarriers, wherein the N subcarriers comprise the anchor carrier and at least one supplementary carrier, wherein at least one first subcarrier of the N subcarriers is non-orthogonal with a second subcarrier of the N subcarriers, and wherein N is an integer greater than or equal to 2;

    acquiring, by the UE, on the anchor carrier, system information, wherein the system information comprises information about identities and frequency locations of the subcarriers;

    selecting, by the UE, one of the anchor carrier or a supplementary carrier according to the system information; and

    accessing, by the UE, on a selected subcarrier, the base station, and communicating with the base station;

    wherein a spacing between a downlink center frequency of the supplementary carrier and a downlink center frequency of the anchor carrier is an integral multiple of a frequency domain width of a resource block (RB);

    wherein a spacing between an uplink center frequency of the supplementary carrier and an uplink center frequency of the anchor carrier is an integral multiple of the frequency domain width of the RB; and

    wherein the downlink center frequency of the anchor carrier coincides with a downlink center frequency of a Long Term Evolution (LTE) system, and wherein the downlink center frequency of the supplementary carrier coincides with an orthogonal frequency division multiplexing (OFDM) subcarrier of the LTE system.
