User apparatus, base station, and preamble transmission method
A user apparatus in a radio communication system including a base station and the user apparatus, including: a reception unit configured to receive a plurality of predetermined signals transmitted from the base station using a plurality of beams; and a transmission unit configured to transmit a preamble using a plurality of resources corresponding to the plurality of beams, wherein the reception unit receives, from the base station, system information including information of the plurality of resources corresponding to the plurality of beams, and the transmission unit obtains the information of the plurality of resources from the system information.
1. A terminal comprising:
a receiver configured to receive synchronization signal blocks corresponding to beams; and
a transmitter configured to transmit a preamble using one of resources corresponding to the synchronization signal blocks,
wherein the receiver receives a system information block (SIB), that is transmitted by a beam, out of SIBs transmitted by beams, and
wherein each of the SIBs includes information of the resources.
2. A preamble transmission method executed by a terminal, comprising:
a reception step of receiving synchronization signal blocks corresponding to beams; and
a transmission step of transmitting a preamble using one of resources corresponding to the synchronization signal blocks,
wherein, in the reception step, the terminal receives a system information block (SIB), that is transmitted by a beam, out of SIBs transmitted by beams, and
wherein each of the SIBs includes information of the resources.
3. A base station comprising:
a transmitter configured to transmit synchronization signal blocks corresponding to beams; and
a receiver configured to receive a preamble using one of resources corresponding to the synchronization signal blocks,
wherein the transmitter transmits system information blocks (SIBS) by beams, and
wherein each of the SIBs includes information of the resources.
4. A system comprising a terminal and a base station,
the terminal comprising:
a first receiver configured to receive synchronization signal blocks corresponding to beams; and
a first transmitter configured to transmit a preamble using one of resources corresponding to the synchronization signal blocks,
wherein the first receiver receives a system information block (SIB), that is transmitted by a beam, out of SIBs transmitted by beams, and wherein each of the SIBs includes information of the resources,
the base station comprising:
a second transmitter configured to transmit the synchronization signal blocks corresponding to the beams; and
a second receiver configured to receive the preamble using one of the resources corresponding to the synchronization signal blocks,
wherein the second transmitter transmits the system information blocks (SIBs) by the beams.
