Abstract: A bandwidth resource switching method and apparatus are provided. When a network device sends bandwidth resource indication information to a terminal by using downlink control information, the network device may impose some constraints on uplink transmission mode-related configuration information or SRS-related configuration information on an indicated bandwidth resource, and other indication information carried in the downlink control information, so that no ambiguity occurs when the terminal parses the bandwidth resource indication information. Alternatively, when a side of a terminal receives bandwidth resource indication information sent by a network device by using downlink control information, the terminal parses, in an unambiguous interpretation manner, configuration information on a bandwidth resource indicated by the bandwidth resource indication information in the downlink control information.

Abstract: This application provides a minimization of drive tests (MDT) measurement solution, which may be used to implement an MDT measurement of a network device with an architecture in which a central unit (CU) entity and a distributed unit (DU) entity are separated. A centralized unit control plane (CU-CP) determines configuration information, and sends the configuration information to a centralized unit user plane (CU-UP) of the network device. The configuration information is used to perform an MDT measurement on a measurement object. The solution in this application may be applied to a communications system, for example, may be applied to a 5th generation (5G) network.

Abstract: Apparatus and methods for operating wireless devices using unlicensed frequency ranges with minimal transmission interruptions. In one embodiment, the apparatus and methods provide a mechanism for redirecting idle or inactive wireless devices to different frequencies in response to interference detection such as by 5 GHz-band radar. In one variant, the present disclosure provides methods and apparatus for allowing user device (UEs) using 5G NR-U spectrum to continue to operate upon radar detection by successfully switching the UEs to one or more frequencies that are free of radar operation. In one variant, a gNB controlling the UEs informs the AMF (access and mobility function) of a radar detection event, and the AMF initiates a paging towards idle UEs in order to allow the gNB to move the UEs to a frequency without radar operations. In another variant, a gNB switches its UEs to a different frequency without relying on the AMF.
