A signal transmission method, comprising: receiving, by a user equipment, an indication signal, wherein the indication signal is used to indicate resource numbers of physical resources occupied by one or more control signals, wherein the resource number comprises time information and frequency information of the physical resource; allocating, by the user equipment according to the resource numbers, corresponding physical resources to the one or more control signals; and sending, by the user equipment, the one or more control signals, wherein the resource numbers are determined after the physical resources occupied by the one or more control signals are grouped, the time information is a time sequence number, and the frequency information is a frequency sequence number, wherein: a same resource number in different physical resource groups is corresponding to a same time sequence number and a same frequency sequence number; or a same resource number in different physical resource groups is corresponding to a same time sequence number and different frequency sequence numbers; or a same resource number in different physical resource groups is corresponding to different time sequence numbers and a same frequency sequence number; or a same resource number in different physical resource groups is corresponding to different time sequence numbers and different frequency sequence numbers. receiving, by a user equipment, an indication signal, wherein the indication signal is used to indicate resource numbers of physical resources occupied by one or more control signals, wherein the resource number comprises time information and frequency information of the physical resource; allocating, by the user equipment according to the resource numbers, corresponding physical resources to the one or more control signals; and sending, by the user equipment, the one or more control signals, wherein the resource numbers are determined after the physical resources occupied by the one or more control signals are grouped, the time information is a time sequence number, and the frequency information is a frequency sequence number, wherein: a same resource number in different physical resource groups is corresponding to a same time sequence number and a same frequency sequence number; or a same resource number in different physical resource groups is corresponding to a same time sequence number and different frequency sequence numbers; or a same resource number in different physical resource groups is corresponding to different time sequence numbers and a same frequency sequence number; or a same resource number in different physical resource groups is corresponding to different time sequence numbers and different frequency sequence numbers. a same resource number in different physical resource groups is corresponding to a same time sequence number and a same frequency sequence number; or a same resource number in different physical resource groups is corresponding to a same time sequence number and different frequency sequence numbers; or a same resource number in different physical resource groups is corresponding to different time sequence numbers and a same frequency sequence number; or a same resource number in different physical resource groups is corresponding to different time sequence numbers and different frequency sequence numbers.
