AI Technical Summary

Technical Problem

In wireless communication systems, existing technologies struggle to achieve real-time dynamic spectrum sharing between base stations, especially in CU and DU separation structures, where time delays and limited information elements exist, resulting in low spectrum sharing efficiency.

Method used

By introducing a direct interface and related signaling between the distributed units (DUs) of the base station, the transmission of spectrum sharing information, including identification information and resource coordination, is realized, supporting dynamic spectrum sharing (DSS) between CUs and DUs.

Benefits of technology

It improves the real-time performance and efficiency of spectrum sharing, reduces time delay, and enhances the flexibility of spectrum utilization and communication performance.

Abstract

The disclosure relates to a fifth generation (5G) or pre-5G communication system to support a higher data transmission rate beyond a fourth generation (4G) communication system such as long term evolution (LTE). According to various embodiments of the disclosure, an apparatus operated by a distributed unit (DU) of a base station in a wireless communication system includes at least one transceiver and at least one processor. The at least one processor controls the at least one transceiver to transmit, to another node supporting a second cell, a message including information related to spectrum sharing via a DU interface, the second cell sharing a frequency band within a specified range with a first cell of the base station. The information related to spectrum sharing can include identification information about the first cell and identification information about the second cell.
