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:
operate in two or more parts of a bandwidth for downlink, the two or more parts of the bandwidth comprising a first part associated with a first identifier identifying a serving cell and a second part associated with the first identifier, and
send, to a second base station, configuration information related to the second part,
wherein the configuration information comprises:
a second identifier identifying the second part,
first information indicating a bandwidth of the second part, and
second information identifying to the first part.
2. The first base station according to claim 1 , wherein the first identifier is a Physical layer Cell Identifier or a Cell Global Identifier (CGI).
3. A method performed by a first base station, the method comprising:
configuring the first base station to operate in two or more parts of a bandwidth for downlink, the two or more parts of the bandwidth comprising a first part associated with a first identifier identifying a serving cell and a second part associated with the first identifier, and
sending, to a second base station, configuration information related to the second part,
wherein the configuration information comprises:
a second identifier identifying the second part,
first information indicating a bandwidth of the second part, and
second information identifying to the first part.
4. The method according to claim 3 , wherein the first identifier is a Physical layer Cell Identifier or a Cell Global Identifier (CGI).
5. 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:
operate in two or more parts of a bandwidth for downlink, the two or more parts of the bandwidth comprising a first part associated with a first identifier identifying a serving cell and a second part associated with the first identifier, and
communicate, based on the two or more parts of the bandwidth, with a first base station configured to send configuration information related to the second part to a second base station
wherein the configuration information comprises:
a second identifier identifying the second part,
first information indicating a bandwidth of the second part, and
second information identifying to the first part.
6. The UE according to claim 5 , wherein the first identifier is a Physical layer Cell Identifier or a Cell Global Identifier (CGI).
7. A method of a user equipment (UE), the method comprising:
configuring the UE to operate in two or more parts of a bandwidth for downlink, the two or more parts of the bandwidth comprising a first part associated with a first identifier identifying a serving cell and a second part associated with the first identifier, and
communicating, based on the two or more parts of the bandwidth, with a first base station configured to send configuration information related to the second part to a second base station,
wherein the configuration information comprises:
a second identifier identifying the second part,
first information indicating a bandwidth of the second part, and
second information identifying to the first part.
8. The method according to claim 7 , wherein the first identifier is a Physical layer Cell Identifier or a Cell Global Identifier (CGI).
