Random access method, terminal, and base station

A random access method, comprising:

• determining, by a base station, configuration information of a first random access resource and configuration information of a second random access resource;
• sending, by the base station, to a terminal (UE) the configuration information of the first random access resource by using a system broadcast;
• and
• sending, by the base station, to the UE the configuration information of the second random access resource by using downlink control information (DCI).

A terminal (UE), comprising:

• a receiving unit configured to receive configuration information of random access resources from a base station, wherein the configuration information of the random access resources comprises:
• configuration information of a first random access resource received from the base station by using a system broadcast and configuration information of a second random access resource received from the base station by using downlink control information (DCI);
• a selection unit configured to select a random access resource from the first random access resource and the second random access resource according to a random access rule and the configuration information of the random access resources received from the base station;
• and
• an access unit configured to initiate random access according to the selected random access resource.
