RANDOM ACCESS APPARATUS AND METHOD

摘要

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.

主权项

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; wherein the 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.
