摘要
5G室内频率使用许可的发放进一步推动了我国5G系统部署和商用进程,为高效合理地使用该段频率,满足室内场景上行业务占比较高的业务需求,研究了3 300~3 400 MHz频段5G NR系统在室内场景部署时的TDD非同步干扰情况。分析了不同功率参数设置下2个干扰场景的仿真结果。最后给出5G NR系统在室内场景下采用不同TDD配置的共存建议及共存措施。
The issuance of the 5G frequency License for indoor scenario has further promoted the deployment and commercialization of5G system in our country.In order to use this frequency efficiently and meet the high demand for uplink services in indoor scenarios,the TDD asynchronous interference of 5G NR system in 3 300~3 400 MHz band for indoor scenario is studied.The simulation results of two interference scenarios under different power parameter settings are analyzed.Finally,the coexistence recommendations and coexistence measures for 5G NR systems using different TDD configurations in indoor scenarios are given.
