    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 discloses a resource determining method, abase station, and a user equipment. The method includes: determining a first narrowband resource available to an MTC terminal according to UE information in a random access process and/or common information of a cell; and transmitting control information and/or data on the first narrowband resource. According to the solutions of this application, in a case where the MTC terminal cannot receive RRC signaling, the narrowband resource available to the MTC terminal can still be determined beforehand, and communication between the MTC terminal and a network-side device is implemented by using the narrowband resource.

    Abstract: A method for randomly accessing a network, a terminal, and a base station where the method includes acquiring, by a machine type communication (MTC) terminal, predefined random access resources when random access resources corresponding to the MTC terminal are insufficient, where the predefined random access resources are random access resources corresponding to the MTC terminal, or the predefined random access resources are random access resources except random access resources corresponding to the MTC terminal, and initiating, by the MTC terminal, a random access process using the acquired predefined random access resources, and when the random access resources corresponding to the MTC terminal are insufficient, the MTC terminal initiates the random access process using the acquired predefined random access resources, such that a probability that a conflict occurs in randomly accessing a network is reduced, and random access resource utilization is improved.

    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.
