RESOURCE CONFIGURATION METHOD, METHOD AND APPARATUS FOR OBJECT DISCOVERY AND COMMUNICATION SYSTEM

摘要

The embodiments of the present invention provide a resource configuration method, method and apparatus for object discovery and a communication system. The resource configuration method includes: a base station configures resources used for transmitting a D2D discovery signal sequence and/or a D2D reference signal for a communication device performing a D2D communication, wherein, in time domain, for a conventional cyclic prefix (CP), the resources occupy the sixth and/or the seventh SC-FDMA symbol of each sub-frame, and for extended CP, the resources occupy the fifth and/or the eleventh SC-FDMA symbol of each sub-frame; and in frequency domain, the location of PRB occupied by the resources are a set of PRB in which PRBs are continuous or incontinuous, and the subcarriers occupied by the resources are all or part of subcarriers of the each PRB occupied by the resources. With the method of the embodiments of the present invention, the resources used for transmitting D2D discovery signal are configured for the D2D communication, while the object discovery and synchronization are achieved, the interference of the D2D communication to cellular communication is reduced.
