    摘要: Embodiments of the present invention disclose methods and apparatuses for receiving and sending a control channel, and are applicable to the field of communications technologies. In the embodiments of the present invention, a base station carries scheduling information of a user equipment of an R11 system in both the PDCCH region and the E-PDCCH region of a downlink subframe. In this way, the user equipment needs to detect the control channel within the PDCCH region and the E-PDCCH region, so that resources of the two regions are available to the user equipment of the R11 system. Moreover, the user equipment detects only the control channel of the first type in the PDCCH region, and detects control channels of the other type in the E-PDCCH region. The method in the embodiments of the present invention does not increase the number of control channel detections.

    摘要: Embodiments of the present invention 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; and performing enhanced transmission of the control information according to the first parameter. Between a base station and UE, a k th 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 j th 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. The UE can determine a quantity of repetitions of enhanced transmission of the control information according to one or more of the preset start subframe, the preset radio frame, and the first parameter. Therefore, the user equipment can accurately determine the last subframe and/or radio frame occupied by the control information, and further, can accurately determine a start time for receiving the repeatedly transmitted PDSCH or a start time for repeatedly transmitting the PUSCH, thereby ensuring performance of the PDSCH or PUSCH, where the start time includes the start subframe and/or the start radio frame.

    摘要: The present invention discloses a method and a device for transmitting channel state information, where the method includes: determining, by a first network device according to measurement of a reference signal sent by a second network device, channel state information including a precoding matrix indication PMI and selection information that is used to instruct to select a matrix element in a precoding matrix indicated by the PMI; and sending the channel state information to the second network device. Because the channel state information includes the precoding matrix indication PMI used to instruct the second network device to perform precoding and the selection information that is used to instruct to select a matrix element in a precoding matrix indicated by the PMI, the second network device can determine, according to the selection information for the matrix element, a precoding matrix for performing precoding, and synthesize a channel precoding matrix applicable to a two-dimensional antenna. Therefore, dimensions of the synthesized precoding matrix are closer to a spatial feature of a real channel, which effectively improves precision of a precoding matrix.
