METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING UE CAPABILITY INFORMATION IN MOBILE COMMUNICATION SYSTEM

摘要

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.

主权项

1. A method for transmitting capability information by a user equipment (UE), the method comprising:
receiving a first message including information that requests at least one frequency band supported by the UE and at least one radio access capability of the UE from an evolved Node B (eNB); generating a second message including capability information based on the first message; and transmitting the second message to the eNB, wherein the capability information comprises at least one carrier aggregation (CA) band combination supported by the UE, and wherein the at least one CA band combination is requested in the first message and includes two downlink frequency bands and one uplink frequency band.
