Description

小区重选的方法、装置、通信设备及存储介质Method, device, communication device and storage medium for cell reselection 技术领域technical field
本公开涉及无线通信技术领域但不限于无线通信技术领域,尤其涉及一种小区重选的方法、装置、通信设备及存储介质。The present disclosure relates to the field of wireless communication technologies, but is not limited to the field of wireless communication technologies, and in particular, to a method, apparatus, communication device, and storage medium for cell reselection.
背景技术Background technique
在第五代移动通信技术新空口(NR,New Radio)中,对于地面网络(TN,Terrestrial Networks)系统中,终端可以根据S准则和R准则进行小区选择和小区重选。在非地面网络(NTN,Terrestrial Networks)系统中,当卫星相对地面有相对移动时,会进行馈线链路交换。这里,馈线链路为卫星与地面网关之间的链路。In the fifth-generation mobile communication technology New Radio (NR, New Radio), for a terrestrial network (TN, Terrestrial Networks) system, the terminal can perform cell selection and cell reselection according to the S criterion and the R criterion. In a non-terrestrial network (NTN, Terrestrial Networks) system, when the satellite moves relative to the ground, the feeder link exchange is performed. Here, the feeder link is the link between the satellite and the terrestrial gateway.
相关技术中,卫星进行馈线链路交换时,会导致终端的小区重选。由于馈线链路交换时,服务小区的信号会突然终止,因此,如果终端仅根据S准则启动对邻区的测量,可能会导致终端不能及时地进行小区重选。In the related art, when the satellite exchanges the feeder link, it will lead to cell reselection of the terminal. Since the signal of the serving cell is suddenly terminated when the feeder link is switched, if the terminal only starts the measurement of the neighboring cell according to the S criterion, the terminal may not be able to perform cell reselection in time.
