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, a base station, and a user equipment. The method includes: determining a first narrowband resource available to an machine type communication (MTC) terminal according to user equipment (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: Embodiments of the present disclosure provide a method for enhanced transmission of control information, user equipment, a base station, and a communications system. The method includes: determining a first parameter for enhanced transmission of control information. Between a base station and UE, a kth subframe after a last subframe in enhanced transmission of control information may be preset as a start subframe in enhanced transmission of a PDSCH, a jth subframe after the last subframe in enhanced transmission of the control information may be preset as a start subframe in enhanced transmission of a PUSCH, and a start subframe in enhanced transmission of the control information is preset, where the subframes may also be radio frames. Therefore, the user equipment can accurately determine the last subframe and/or radio frame occupied by the control information, thereby ensuring performance of the PDSCH or PUSCH.
