Wireless communication system, wireless communication method, radio station and program
A first radio base station informs a second radio base station about the configuration information of a second carrier, such as NBC or EC, not having an individual first identifier, as the configuration information of the second carrier is correlated with a first carrier, such as BC, having the individual first identifier. The radio station has a function of performing communication with a radio terminal using simultaneously a plurality of carriers included in the carrier set.
1. A first base station comprising:
a memory; and
at least one hardware processor coupled with the memory, wherein the at least one hardware processor is configured to:
support two or more downlink carriers including a first carrier associated with a cell identifier and a second carrier associated with the cell identifier, and
send, to a second base station, configuration information related to the second carrier,
wherein the configuration information includes:
a carrier identifier corresponding to the second carrier,
bandwidth information corresponding to the second carrier, and
information indicating the first carrier.
2. A method for a first base station, the method comprising:
supporting two or more downlink carriers including a first carrier associated with a cell identifier and a second carrier associated with the cell identifier,
sending, to a second base station, configuration information related to the second carrier,
wherein the configuration information includes:
a carrier identifier corresponding to the second carrier,
bandwidth information corresponding to the second carrier, and
information indicating the first carrier.
3. A user equipment (UE) comprising:
a memory; and
at least one hardware processor coupled with the memory,
wherein the at least one hardware processor is configured to support two or more downlink carriers including a first carrier associated with a cell identifier and a second carrier associated with the cell identifier, and communicate with a first base station using the two or more downlink carriers,
wherein the first base station is configured to:
support the two or more downlink carriers, and
send, to a second base station, configuration information related to the second carrier,
wherein the configuration information includes:
a carrier identifier corresponding to the second carrier,
bandwidth information corresponding to the second carrier, and
information indicating the first carrier.
4. A method of a user equipment (UE), the method comprising:
supporting two or more downlink carriers including a first carrier associated with a cell identifier and a second carrier associated with the cell identifier, and
communicating with a first base station using the two or more downlink carriers,
wherein the first base station is configured to:
support the two or more downlink carriers, and
send, to a second base station, configuration information related to the second carrier,
wherein the configuration information includes:
a carrier identifier corresponding to the second carrier,
bandwidth information corresponding to the second carrier, and
information indicating the first carrier.
