Abstract  Abstract

The present disclosure discloses a plurality of configuration schemes for coexistence of D2D signals with different CP lengths in D2D communication. In Scheme 1-1, a network allocates a specific CP length for some kind of D2D channel of all users in a cell; in Scheme 1-2, the network configures a specific CP length for each of D2D channels of each user in the cell; in Scheme 2-1, the network configures one CP length for each of D2D subframes; in Schemes 2-2 to 2-4, the system configures a CP length periodically, in which for N D2D subframes within a configuration periodicity, the network configures one CP length for each of (N?M) (M=1, 2) D2D subframes; while for the remaining M (M=1, 2) D2D subframes, the system multiplexes SC-FDMA/OFDM symbols with different CP lengths in a TDM, a FDM, and a TDM & FDM ways, respectively; and in Scheme 2-5, the network configures one CP length for each allocated time-frequency physical resource set.
