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: 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.

Abstract: The present disclosure provides a downlink control signaling sending method and device. The method includes: determining, by a base station, a first transmission type of a first terminal device and a second transmission type of a second terminal device; and sending demodulation information to the first terminal device according to the first transmission type and the second transmission type by using downlink control signaling, where the demodulation information is used to instruct the first terminal device to demodulate a transmission signal of the first terminal device that is received by the first terminal device. In this way, content of the demodulation information to be sent is specifically determined, so as to effectively resolve a problem that, during pairing at a plurality of layers, when different power ratios are configured on different subbands, a large amount of signaling needs to be consumed for notification to the first terminal device.
