說(shuō)明書(shū)
If the quantity c of conflicts of the first UE is greater than the threshold C0, the conflict time w of the first UE is greater than the threshold W0, or the service priority Q of the first UE or the priority of the UE is higher than the threshold Q0, the transmit probability P is 1, or P=f(x), where x is one of N, N-S, N/S, the service priority Q of the first UE, the priority of the UE, a value customized by the first UE, c, w, or a function g(c, w) of c and w, and different values of x are corresponding to different function relationships represented by f(x). For example, P=f1(N), P=f2(N/S), P=f3(N-S), P=f4(Q), P=f5(c), P=f6(w), or P=f7(c, w). A correspondence between a function and a value of x may be stipulated or predefined in a protocol. The present invention includes, but is not limited to, the following function relationship a simple linear relationship P=ax+b, a modulo relationship P=x mod Nt, or a segmentation mapping relationship, where one value of x is corresponding to one value of P that is obtained by means of table lookup, and certainly, a parameter in the function, such as a, b, or Nt, is a predefined parameter.
It should be noted that S is a quantity of UEs in a first group corresponding to the first UE, and N is a quantity of UEs that are in the first group and that send data.
Alternatively, S is a quantity of neighboring UEs of the first UE, N is a quantity of UEs that are in the neighboring UEs of the first UE and that send data, and the neighboring UE of the first UE is UE that can directly communicate with the first UE.
