Abstract: A communication method, a communications apparatus, and a storage medium, used for a terminal device. The method includes: receiving system information from a first cell, where the system information includes first information; and performing cell selection or cell reselection based on the first information. In the embodiments, assistance information, such as a receiving capability of a network device or a sending capability of the terminal device, may be added to the system information. The assistance information includes the first information, so that when performing the cell selection or the cell reselection, the terminal device considers more determining conditions, to prevent some terminal devices with a low sending capability from camping on an NTN that cannot work.

Abstract: A communications method and apparatus that relate to the field of communications technologies, to resolve a problem that a terminal frequently performs TAU because a TAU mechanism of a conventional cellular network is directly used in a non-terrestrial network, thereby increasing energy consumption of the terminal. The method includes: receiving, by a terminal device, tracking area information from an access network device, and determining, based on a second tracking area identity, whether to perform the TAU. The tracking area information includes a first tracking area identity and a second tracking area identity, where the first tracking area identity is a tracking area identity of a first cell, and the second tracking area identity is used by the terminal device to perform the tracking area update TAU. The method is used in a location management process of the terminal.

Abstract: This application provides a resource management method and apparatus. A terminal determines at least one reference signal resource corresponding to each of at least two frequency domain resources, and selects at least two reference signal resources from a plurality of reference signal resources corresponding to the at least two frequency domain resources, where the at least two selected reference signal resources are reference signal resources corresponding to at least two different frequency domain resources. In other words, some of the at least two reference signal resources are selected from a plurality of reference signal resources corresponding to one frequency domain resource, and other reference signal resources are selected from a plurality of reference signal resources corresponding to another frequency domain resource. In this way, the terminal can simultaneously receive data sent by a network device by using reference signal resources corresponding to different frequency domain resources, thereby improving communication efficiency.

Abstract: This application relates to the field of communications technologies, and discloses a resource configuration method and a node. The method includes: sending, by an parent node of a first node, first configuration information to the first node; and then determining, by the first node based on the first configuration information, a second resource for communication between the first node and a child node served by the first node. In this way, the determined second resource can implement orthogonalization between DMRS ports of an access link of the first node and a backhaul link of the first node, and therefore, link performance is improved.

Abstract: Embodiments of this application provide a communication method and an apparatus. A correspondence between a plurality of MCS indexes and a plurality of modulation schemes is provided to achieve flexible selection of a modulation scheme. In the correspondence, at least one MCS index of the plurality of MCS indexes corresponds to a set modulation schemes which comprises π/2 binary phase shift keying (π/2-BPSK) modulation and quadrature phase shift keying (QPSK) modulation. A first communication device receives a target modulation and coding scheme (MCS) index from a second communication device, determines a target modulation scheme corresponding to the target index number based on the correspondence, and performs communication with the second communication device based on the target modulation scheme.
