Embodiments of the present invention provide a communication method, a device, and a base station applied in a WCDMA system. The method includes: sending downlink data with same timing via downlink carriers that are respectively configured in a first communication area, a second communication area, and a third communication area; where the first communication area, the second communication area, and the third communication area are communication areas with every two thereof being adjacent to each other; the downlink carriers covered at edges of any two of the first communication area, the second communication area, and the third communication area have different frequencies; and the communication areas serve as communication cells or communication sectors. According to the embodiments of the present invention, downlink data with same timing is sent via a plurality of communication areas, a user equipment can distinguish synchronisation channels in each communication area according to the frequencies of the downlink carriers, thereby implementing that data is sent synchronously in a plurality of communication areas, and avoiding interference to the UE caused by asynchronous sending of data.
