Abstract
In order to transmit capability information of a user equipment (UE) to an evolved Node B (eNB), the UE may generate a UE CAPABILITY INFORMATION message including the capability information of the UE, and transmit the generated UE CAPABILITY INFORMATION message to the eNB. Here, the capability information of the UE may include at least one band combination supported by the UE and whether Time Division Duplexing-Frequency Division Duplexing Carrier Aggregation (TDD-FDD CA) for the band combination is supported.
Claims15
A method for transmitting capability information by a terminal, the method comprising:
- receiving, from a base station, a user equipment (UE) capability enquiry message including first information that requests at least one frequency band supported by the terminal and second information that requests at least one radio access capability of the terminal;
- generating a UE capability information message including capability information based on the UE capability enquiry message;
- and
- transmitting, to the base station, the UE capability information message,
- wherein the capability information comprises at least one carrier aggregation (CA) band combination supported by the terminal, and
- wherein the at least one CA band combination is requested based on the first information included in the UE capability enquiry message and includes two downlink frequency bands and one uplink frequency band.
A method for receiving capability information by a base station, the method comprising:
- generating a user equipment (UE) capability enquiry message including first information that requests at least one frequency band supported by a terminal and second information that requests at least one radio access capability of the terminal;
- transmitting, to the terminal, the UE capability enquiry message;
- and
- receiving, from the terminal, a UE capability information message including capability information corresponding to the UE capability enquiry message,
- wherein the capability information comprises at least one carrier aggregation (CA) band combination supported by the terminal, and
- wherein the at least one CA band combination is requested based on the first information included in the UE capability enquiry message and includes two downlink frequency bands and one uplink frequency band.
A terminal for transmitting capability information, the terminal comprising:
- a transceiver configured to transmit and to receive a signal;
- and
- a controller configured to:
- receive a user equipment (UE) capability enquiry message including first information that requests at least one frequency band supported by the terminal and second information that requests at least one radio access capability of the terminal from a base station,
- generate a UE capability information message including capability information based on the UE capability enquiry message, and
- transmit the UE capability information message to the base station,
- wherein the capability information comprises at least one carrier aggregation (CA) band combination supported by the terminal, and
- wherein the at least one CA band combination is requested based on the first information included in the UE capability enquiry message and includes two downlink frequency bands and one uplink frequency band.
A base station for receiving capability information, the base station comprising:
- a transceiver configured to transmit and to receive a signal;
- and
- a controller configured to:
- generate a user equipment (UE) capability enquiry message including first information that requests at least one frequency band supported by a terminal and second information that requests at least one radio access capability of the terminal,
- transmit the UE capability enquiry message to the terminal, and
- receive a UE capability information message including capability information corresponding to the UE capability enquiry message from the terminal,
- wherein the capability information comprises at least one carrier aggregation (CA) band combination supported by the terminal, and
- wherein the at least one CA band combination is requested based on the first information included in the UE capability enquiry message and includes two downlink frequency bands and one uplink frequency band.
