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.

Abstract: The present application discloses a control information sending method that includes: determining, from a preset set of patterns, a pattern as a first pattern, where the pattern comprised in the preset set of patterns is one or more patterns that are determined according to a coverage enhancement degree. The pattern determines an aggregation level that is used for transmitting control information, and determines the number of the multiple subframes, and also determines a resource indicator for a resource that is used for transmitting the control information. The pattern further determines a control information format that is used for transmitting, in each subframe of the multiple subframes, the control information. The method further includes: acquiring, according to the first pattern, the control information on a resource, to which the control information is mapped, in each subframe of the multiple subframes.
