Base station, in a mobile communication system that performs an adjustment of uplink transmission timing by random access between a user equipment and the base station |
摘要 |
A base station in a mobile communication system containing a user equipment and the base station that includes an uplink (UL) resource management unit that allocates a plurality of parameters related to a physical uplink control channel (PUCCH) resource used for transmission processing, between the user equipment and the base station; a reception processing unit that receives a signal sent from the user equipment including a transmission processing unit that performs transmission processing based on transmission timing adjustment information; and a control unit that, if a valid term of first transmission timing adjustment information expires before transmission processing of a signal including identification information of the user equipment is performed during connection processing while performing the connection processing to the base station based on the first transmission timing adjustment information, aborts the connection processing and releases at least one of the allocated plurality of parameters related to the PUCCH resource. |

1. A base station in a mobile communication system having a user equipment and the base station, the base station comprising:
a processor configured to allocate a plurality of parameters related to a physical uplink control channel (PUCCH) resource used for a transmission process, between the user equipment and the base station; and a receiver configured to receive a signal sent from the user equipment, the user equipment being configured to:
perform a transmission based on transmission timing adjustment information; andif a valid term of first transmission timing adjustment information expires before transmission of a signal including identification information of the user equipment by the user equipment is performed during a connection process while the user equipment performs the connection process to the base station using the first transmission timing adjustment information:abort the connection process; andrelease a plurality but less than all of the allocated plurality of parameters related to the PUCCH resource. |
