The invention relates to a user classification method for the
relay auxiliary
data transmission of the
wireless communication, which belongs to the
wireless data transmission technology field. One of the technical proposals of the method is that: a Kth user is arranged in the communication
system, the large scale of the straight link is declined to Mu0k when the data is received, the large scale between a
base station and a
relay is declined to Mu1, the large scale between the
relay and the users is declined to Mu2k, wherein, the Mu0k can be taken as the measurement of the straight link, the
harmonic mean 2Mu1* Mu2k / (Mu1+ Mu2k) of the Mu1 and the Mu2k can be taken as the measurement of the relay link, if the Mu0k is bigger than or equals to the 2Mu1* Mu2k / (Mu1+ Mu2k), the kth user can be placed into the straight user congregation, if the Mu0k is smaller than the 2Mu1* Mu2k / (Mu1+ Mu2k), the k user can be placed into the relay user congregation, and above operation is executed to all users in the ergodic communication
system, so as to obtain the straight user congregation and the relay user congregation. The method can effectively alleviate the effects to the communication
system performance due to the
signal channel lager scale decline, so as to enable the speed of the system to be improved.
