1. A data transmission method, comprising:
receiving, by a first communication node, first information sent from a second communication node, wherein the first information comprises configuration information of a transmission resource;
wherein the configuration information of the transmission resource comprises offset configuration information of frequency domain resource information of a non-contention-based random access resource, the offset configuration information of the frequency domain resource information of the non-contention-based random access resource comprises N carriers, and N is a positive integer; under a condition that mi subcarrier resources are configured on each carrier i in the N carriers, an initial frequency domain resource group of the non-contention-based random access resource comprises M resources, and M=Σi=1Nmi; the method further comprises:
sending, by the first communication node, a second air interface transmission to the second communication node according to an initial frequency domain resource of the non-contention-based random access resource after receiving a first air interface transmission sent from the second communication node; and
the initial frequency domain resource of the non-contention-based random access resource is obtained through at least one of following manners:
determining, by the first communication node, an offset of the frequency domain resource information of the non-contention-based random access resource according to the offset configuration information of the frequency domain resource information of the non-contention-based random access resource; obtaining, by the first communication node, the initial frequency domain resource of the non-contention-based random access resource from the initial frequency domain resource group of the non-contention-based random access resource according to the offset of the frequency domain resource information of the non-contention-based random access resource;
conducting, by the first communication node, a modulo operation using a terminal identifier as a dividend and M as a divisor to determine the initial frequency domain resource of the non-contention-based random access resource;
conducting, by the first communication node under a condition that a carrier quantity of the first air interface transmission is larger than M, a modulo operation using a carrier number for detecting the first air interface transmission at a current moment as a dividend and M as a divisor to determine the initial frequency domain resource of the non-contention-based random access resource; and
conducting, by the first communication node under a condition that a carrier quantity of the first air interface transmission is smaller than M, a modulo operation using each resource number in the initial frequency domain resource group of the non-contention-based random access resource as a dividend and the carrier quantity for detecting the first air interface transmission as a divisor to determine the initial frequency domain resource of the non-contention-based random access resource.
