Random access apparatus and method
First Claim
1. Random access user equipment, comprising:
- a receiving module, configured to receive a notification message sent by a base station, wherein the notification message is used to instruct the user equipment (UE) to execute a random access procedure, and the notification message carries at least one of the following configuration parameters;
a random access code used by the UE to execute the random access procedure;
orinformation about a physical random access channel (PRACH) resource that is configured on an unlicensed spectrum and that is used by the UE to execute the random access procedure;
a processing module, configured to determine, according to the configuration parameter in the notification message received by the receiving module, a PRACH resource used to execute the random access procedure; and
a sending module, configured to send the random access code to the base station on the PRACH resource determined by the processing module;
whereinthe receiving module is configured to receive a random access response message sent by the base station, and determine, according to the random access response message, that the random access procedure is successfully completed.

Abstract
Embodiments of the present invention provide random access user equipment, including: a receiving module, configured to receive a notification message sent by a base station, where the notification message is used to instruct the user equipment UE to execute a random access procedure; a processing module, configured to determine, according to a configuration parameter in the notification message received by the receiving module, a PRACH resource used to execute the random access procedure; and a sending module, configured to send a random access code to the base station on the PRACH resource determined by the processing module; where the receiving module is configured to receive a random access response message sent by the base station. The embodiments of the present invention further provide a random access method. The present invention has an advantage that executing the random access procedure on an unlicensed spectrum can be implemented.
