Method and apparatus for receiving signals in device-to-device wireless communication

The invention relates to a method of signal reception in a terminal device for a wireless communication device and the device. In the present invention, D2D receiving terminal to perform energy detection on the entire symbol region or part of the symbol regions that may be performing a measurement, or is within PSBCH and DM RS synchronization sub-frame transmitted to the DM RS that is sent with the PSBCH PSBCH decoding retry can be used to determine whether the criteria. If the DM RS or the measured level of energy detection level is greater than a predetermined threshold value, the D2D receiving terminal may retry a recognition and a certain amount of time or for a predetermined number of times that the decoding PSBCH PSBCH is transmitted. If DM RS measurement levels or energy detection level is less than the predetermined threshold value, the D2D receiving terminal may not try the decoding has not been recognized and PSBCH PSBCH is transmitted. If not retry the PSBCH decoding, the D2D receiving terminal can try different PSSS / SSSS detection. Through the present invention D2D receiving terminal it can, even though not PSBCH the transmission and avoid the inefficient operation of re-attempting to PSBCH decoded for a certain period of time or a predetermined number of attempts.
