Random Access Method, Apparatus, and System, Terminal, and Base Station

A random access method, wherein the method comprises:

• determining, by a terminal, at least two types of random access resources, wherein the at least two types of random access resources comprise a first-type random access resource and a second-type random access resource;
• and different types of random access resources are in a one-to-one correspondence with different sending beam forms of the terminal;
• or the first-type random access resource is associated with resources of different downlink signals, and the second-type random access resource is not associated with the resources of the different downlink signals;
• or the first-type random access resource is associated with resources of different downlink signals in a first association manner, and the second-type random access resource is associated with the resources of the different downlink signals in a second association manner, wherein the first association manner is different from the second association manner;
• and
• sending, by the terminal, a random access preamble by using the first-type random access resource or the second-type random access resource.

A random access apparatus, wherein the apparatus comprises:

• a processor;
• a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions to:
• configure at least two types of random access resources, wherein the at least two types of random access resources comprise a first-type random access resource and a second-type random access resource;
• and different types of random access resources are in a one-to-one correspondence with different sending beam forms of a terminal;
• or the first-type random access resource is associated with resources of different downlink signals, and the second-type random access resource is not associated with the resources of the different downlink signals;
• or the first-type random access resource is associated with resources of different downlink signals in a first association manner, and the second-type random access resource is associated with the resources of the different downlink signals in a second association manner, wherein the first association manner is different from the second association manner;
• and
• a receiver, configured to receive a random access preamble that is sent by the terminal by using the first-type random access resource or the second-type random access resource.
