Abstract: Example communication methods and apparatus are described. One example communication method includes receiving signaling on a first carrier by a terminal device. The terminal device determines slot formats of N slots on at least one second carrier, where the slot formats of the N slots are determined based on M slot formats. N and M are positive integers. The M slot formats are obtained based on the received signaling, and the N slots are determined based on at least one of the following: a moment at which the signaling is received, and a relationship between a length of a first slot on the first carrier and a length of a second slot on the at least one second carrier. According to the communication method, the terminal device, and a network device in this application, slot formats of slots on a plurality of carriers can be determined.

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.
