Abstract
The present invention discloses a method for D2D communication. The method includes carrying control information and data information, to be sent, in a physical resource block, wherein the physical resource block comprises M OFDM symbols in the time domain and N subcarriers in the frequency domain. The control information comprises at least one of MCS, RV, and NDI, at least one of the MCS, the RV, and the NDI being mapped onto an RE in a high frequency part of the physical resource block. The data information is mapped onto a blank RE in the physical resource block excluding the RE onto which the control information is mapped. The method also includes sending the physical resource block to a target user equipment on a D2D communication link. Spectral efficiency and data transmission rate can be improved by reasonably configuring an uplink physical channel of D2D communication.
