Embodiment Construction

[0042] Aiming at the problem of not providing diversity mode transmission control information in the prior art, the embodiments of the present invention provide a method and device for transmitting control information in diversity mode, and a method and device for receiving transmission control information. The method for transmitting control information in the embodiment of the present invention is as follows: determine multiple enhanced control channel elements E-CCEs for transmitting E-PDCCH, each E-CCE contains the same number of E-REGs, and each E-CCE contains The multiple E-REGs belong to different frequency resource blocks RB; each downlink control information DCI that needs to be transmitted on the E-PDCCH is carried in at least one E-CCE for transmission. By adopting the technical solution of the present invention, since the multiple E-REGs included in each E-CCE belong to different frequency resource block RBs, each DCI that needs to be transmitted is carried on at least

Abstract

The invention discloses a method and a device for transmitting control information, and provides a diversity transmission model-based control information transmitting mode. The method for transmitting the control information comprises the following steps of: ensuring that each enhanced-control channel elements E-CCE for transmitting an enhanced-physical downlink control channel (E-PDCCH) comprises a plurality of enhanced-resource element groups (E-REGs) with the same quantity, and the E-REGs of each E-CCE are respectively assigned to different frequency RB (resource blocks); and bearing each downlink control information (DCI) transmitted on the E-PDCCH into at least one E-CCE to be transmitted. Each part in one DCI is respectively borne on a plurality of different frequency bands which correspond to the E-PDCCH to be transmitted, so that the transmitting stability and reliability of the DCI can be improved.
