Abstract: The present invention discloses a method, a device and a system for transmitting an enhanced downlink control channel, which belong to the communications field. The method for sending an enhanced downlink control channel includes: presetting a multiplexing unit, where the multiplexing unit includes at least one resource block pair, and the at least one resource block pair includes E-PDCCH resources and DM RS resources, and the E-PDCCH resources include multiple control channel elements; sending at least one E-PDCCH corresponding to at least one UE in at least one control channel element of the multiplexing unit, and sending the DM RS corresponding to the at least one UE. The present invention reduces the granularity of an enhanced downlink control channel, saves resources and enhances the downlink control channel, thereby providing more control channels for the UE to use.

Abstract: 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.

Abstract: A signal transmission method, system and device are described. When measuring a reference signal and determining channel quality, a user equipment (UE) obtains a difference between codeword-to-CSI-RS mapping relationships by using a channel quality measurement model. The UE, using a measurement, calculates an optimized mapping relationship. The UE determines at least one mapping relationship from the mapping relationships, to adjust a codeword-to-CSI-RS mapping relationship of a channel.
