摘要： A determination method for a transmission channel in a millimeter wave system, a signal transmission method, a determination apparatus for a transmission channel in a millimeter wave system, a signal transmission apparatus, a millimeter wave system, a computer device, and a computer-readable medium. The determination method comprises: constructing a beam space channel model of a millimeter wave system, wherein the beam space channel model uses a matrix having sparsity to represent sub-beams in the millimeter wave system, and elements in the matrix respectively represent channel gains of the sub-beams in the millimeter wave system; obtaining a beam space channel matrix of a valid user in the beam space channel model; and using an energy-concentrated sub-beam in the beam space channel matrix of the valid user as a transmission channel. For the sub-beams of the beam space channel model, the energy-concentrated sub-beam is selected to be reserved, such that the system secrecy capacity is improved, and there is no need to sacrifice part of transmitting power to serve as artificial noise.
