Abstract  Abstract

Multiple configuration solutions for different CP lengths coexistence of D2D signals in D2D communication are disclosed. In solution 1-1 network configures a specific CP length for one kind of D2D channel of all users in a cell; in solution 1-2 network configures a specific CP length for each kind of D2D channel of each user in a cell; in solution 2-1 network configures a CP length for each D2D sub-frame; in solutions 2-2 to 2-4 a system configures a CP length periodically and for N D2D sub-frames in the configuration period network configures a CP length for each D2D sub-frame from the N-M(M=1 2) D2D sub-frames and for the rest M(M=12) D2D sub-frames the system multiplexes SC-FDMA/OFDM symbols with different CP lengths in the mode of Time Division Multiplexing Frequency Division Multiplexing and Time and Frequency Multiplexing respectively; in solution 2-5 network configures a CP length for each distributed time frequency physical resource set.
