Title:
COMMUNICATION METHOD, APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/101386
Kind Code:
A1
Abstract:
The embodiments of the present invention provide a communication method, apparatus and system. The communication apparatus comprises: a Base-Band Unit (BBU) and two remote radio units RRU0 and RRU1; wherein the BBU is used for controlling a first logical cell including the physical cells covered by the RRU0 and by RRU1; the physical cells covered by the RRU0 overlap with the physical cells covered by the RRU1 in a first region part; the RRU0 and the RRU1 are used for respectively sending a first downlink signal on a frequency f0, and sequentially, respectively sending a second downlink signal on a first frequency and a second frequency; wherein, the first frequency is the difference between f0 and a first offset correction value fd_dl_0, and the second frequency is the sum of f0 and the second offset correction value fd_dl_1; wherein, at least one of fd_dl_0 and fd_dl_1 is not 0. The communication apparatus can be applied to the communication systems with the networking means utilizing cell combination, facilitating the downlink signal demodulation performance of a mobile terminal.
