Abstract: The application provides a method for transmitting a control channel and a data channel in V2X communication, comprising the following steps of: first, determining, by a UE, resource pool configurations for a PSCCH and a PSSCH and an association relationship between the both; then, determining, by the UE and in PSCCH resource pools or a subset of PSCCH resource pools, PSCCH resources required by one or multiple times of PSCCH transmission, and further determining, in PSSCH resource pools associated with the PSCCH resource pools or in a subset of PSSCH resource pools associated with the subset of PSCCH resource pools, time-frequency domain resources for PSSCH transmission; and finally, transmitting, by the UE, corresponding information on the determined PSCCH and PSSCH resources. By the method provided by the present application, the requirement on low time delay of V2X services can be met, and the implementation complexity of a UE can be effectively controlled.
