Random access method, network device, and terminal

A random access method, comprising:

• receiving, by a terminal, configuration information from a network device, wherein the configuration information includes an index of a quantity of transmitted downlink signals associated with one random access resource, each different index indicates a corresponding different quantity of transmitted downlink signals associated with the one random access resource, and the configuration information indicates at least:
• a quantity of random access preambles transmitted on one random access resource,
• a quantity of contention-based random access preambles transmitted on the one random access resource,
• a quantity of contention-free random access preambles transmitted on the one random access resource,
• the quantity of random access preambles associated with one downlink signal,
• the quantity of contention-free random access preambles associated with the one downlink signal,
• the quantity of contention-based random access preambles associated with the one downlink signal, or
• the quantity of transmitted downlink signals associated with the one random access resource;
• determining, by the terminal, a random access resource associated with a transmitted downlink signal based on the configuration information;
• and
• sending, by the terminal, a random access preamble to the network device based on the random access resource associated with the transmitted downlink signal.

A network device, comprising:
