Disclosed are a method for a UE and a user equipment. The method comprises: in step 1, determining, by a UE, an initial value of a scrambling sequence generator, the initial value being determined by one or more of a first ID, a second ID and a time slot index; in step 2, generating a D2D scrambling sequence; and in step 3, conducting a scrambling operation on D2D data using the D2D scrambling sequence, and sending the D2D data on which the scrambling operation has been conducted. As one embodiment, the second ID is one element in an integer set from 504 to 3080. The present invention enables a D2D UE to reuse an initialization formula of an existing PUSCH scrambling generator, and at the same time, enables a base station to distinguish a D2D signal and an uplink signal, thereby avoiding serious interference generated due to identical scrambling sequences. The present invention can simultaneously support D2D UEs inside cell coverage and outside cell coverage. |
