Abstract
A user apparatus in a radio communication system including a base station and the user apparatus, including: a transmission unit configured to transmit a preamble to the base station; and a reception unit configured to monitor a response for the preamble within a predetermined time window by using predetermined identification information, wherein the reception unit calculates the predetermined identification information using a system frame number.
Claims8
A terminal comprising:
- a transmitter configured to transmit a preamble in uplink;
- a receiver configured to receive a response in downlink;
- and
- a processor configured to determine whether the response is for the preamble or not based on information, included in the response, on a system frame number, wherein the information is not an RA-RNTI,
- wherein, when the information which is not the RA-RNTI is information on a system frame number where the terminal transmitted the preamble, the processor determines that the response is for the preamble.

A base station comprising:
- a receiver configured to receive a preamble in uplink;
- and
- a transmitter configured to transmit a response in downlink;
- wherein the response includes information on a system frame number, the information being used by a terminal for determining whether the response is for the preamble or not, wherein the information is not an RA-RNTI, and
- wherein, when the information which is not the RA-RNTI is information on a system frame number where the base station receives the preamble, the response is determined to be for the preamble.

A communication system comprising:
- a terminal comprising:
- a transmitter configured to transmit a preamble in uplink;
- a receiver configured to receive a response in downlink;
- and
- a processor configured to determine whether the response is for the preamble or not based on information, included in the response, on a system frame number, wherein the information is not an RA-RNTI,
- wherein, when the information which is not the RA-RNTI is information on a system frame number where the terminal transmitted the preamble, the processor determines that the response is for the preamble, and
- a base station comprising:
- a receiver configured to receive the preamble in uplink;
- and
- a transmitter configured to transmit the response in downlink.
7 more elements
A communication method performed by a terminal, comprising:
- transmitting a preamble in uplink;
- receiving a response in downlink;
- and
- determining whether the response is for the preamble or not based on information, included in the response, on a system frame number, wherein the information is not an RA-RNTI,
- wherein, when the information which is not the RA-RNTI is information on a system frame number where the terminal transmitted the preamble, the terminal determines that the response is for the preamble.
