AI Technical Summary

Technical Problem

Prior Art In multi-carrier aggregation system, network-side devices are unable to be compatible with the new extended aggregation bandwidth level reported by terminal devices through signaling, resulting in waste of resources and failure of configuration.

Method used

Through the combination of the first signaling and the second signaling, the terminal device reports the supported aggregate bandwidth level to the network side device and parses and identifies the fallback aggregate bandwidth level in the network side device to ensure compatibility and effective resource configuration.

Benefits of technology

It avoids the network side equipment not being able to recognize the newly extended aggregate bandwidth level, ensures effective allocation and utilization of resources, and improves system compatibility and efficiency.

Abstract

The embodiment of the present application discloses a method and device for reporting multi-carrier aggregation capability, which can be applied to long term evolution (LTE) system, fifth generation (5G) mobile communication system, 5G new radio (NR) system, or other future new mobile communication systems and other communication systems. The method includes reporting the aggregation bandwidth level or aggregation capability information supported by the terminal device to the network side device through a first signaling, and reporting the aggregation bandwidth level supported by the terminal device to the network side device through a second signaling; wherein the aggregation bandwidth level reported by the second signaling is the fallback aggregation bandwidth level of the aggregation bandwidth level reported by the first signaling. By implementing the embodiment of the present application, the aggregation bandwidth level supported by the terminal device can be reported according to the first signaling and the second signaling. In this way, it can be avoided that the network side device is incompatible with the aggregation bandwidth level contained in the first signaling, which is conducive to avoiding resource waste.
