Abstract: A random access method method is implemented by a first apparatus including n antenna panels, where n is an integer greater than or equal to 2. In the method, the first device sends, by k antenna panels among the n antenna panels, at least one random access preamble individually to a second device, 1≤k≤n, and k being an integer. The first device monitors, with the k antenna panels, at least one Random Access Response (RAR) returned by the second device. The at least one RAR is returned by the second device in response to the at least one random access preamble sent by the k antenna panels.
