Abstract: Operation information corresponds to a first operation, where the operation information includes touch information and/or posture information of a terminal device, and manages the terminal device based on a matching degree between the operation information corresponding to the first operation and a first decision model, where the first decision model is determined based on operation information of an operation performed by a first user. According to a terminal device management method, because an operation of a user is habitual, a same user (namely, the first user) may generate a large quantity of similar operations in a process of operating the terminal device. Training is performed by using a plurality of operations of the first user, and a decision model is obtained. Based on the decision model, it can be determined whether an operation is performed by the first user.

Abstract: The application pertains to determining a rank of channel loss extent. A base station sends to a terminal a signaling indicating that there are N ranks of channel loss extent. Each rank has a corresponding number of random access preamble repetitions. The base station receives from the terminal device one or more transmissions of a random access preamble in a first number of repetitions of the random access preamble. The base station determines the rank of channel loss extent according to a random access preamble group in which the received random access preamble is located, or the first number of repetitions of the received random access preamble. A channel loss is a reference signal received power (RSRP). After determining the rank of channel loss extent, the base station determines a second number of repetitions corresponding to the determined rank of channel loss extent, for sending or receiving uplink/downlink information.

Abstract: This application describes a data transmission method, a communications apparatus, a storage medium, and a program product. In one example implementation, a network device is no longer confined to allocating an RB only in a narrowband to BL/CE UE, but can also allocate an RB outside the narrowband to the BL/CE UE, so that resources are flexibly allocated by the network device to the BL/CE UE. In this way, when the network device allocates resources to the BL/CE UE in one subframe, a quantity of fragmented resources that cannot be used by conventional UE in remaining resources in a system bandwidth can be reduced, so that the remaining resources can be used by other conventional UE to a maximum extent, thereby improving system resource utilization.

The terminal device determines, based on the resource allocation field, whether the resource block or the subcarrier resource is allocated. The terminal device sends information on the allocated resource block or the subcarrier resource. The method and the device provided in embodiments of the application can be applied to a communications system.
