A method, an apparatus, and a device for transmitting a control channel are disclosed. The method includes: generating at least one eCCE, and transmitting the control channel through the at least one eCCE, where a process of generating each eCCE specifically includes: determining at least two physical resource block PRB pairs for transmitting the control channel, where each PRB pair of the at least two PRB pairs is corresponding to multiple enhanced resource element groups eREGs and the multiple eREGs have eREG attribute information that is not exactly the same; and selecting an eREG from the multiple eREGs corresponding to each PRB pair, where the selected eREGs have different eREG attribute information, and forming an eCCE with the selected eREGs. Embodiments of the present invention are applied to implement generation of an eCCE according to an eREG, so as to transmit an enhanced control channel through the eCCE.
Description
technical field [0001] The present invention relates to the technical field of communication, in particular to a transmission method, device and equipment of a control channel. Background technique [0002] In a wireless communication system such as a Long Term Evolution (LTE) system or an Advanced Long Term Evolution (Long Term Evolution Advanced, LTE-Advanced) system, the downlink multiple access method usually adopts Orthogonal Frequency Division Multiple Access Access (Orthogonal Frequency Division Multiple Access, OFDMA) mode. The downlink resources of the system are divided into Orthogonal Frequency Division Multiplexing (Orthogonal Frequency Division Multiple, OFDM) symbols in terms of time, and are divided into subcarriers in terms of frequency. In the LTE system, a complete physical downlink control channel (Physical Downlink Control Channel, PDCCH) can be mapped to one or several control channel elements (Control Channel Element, CCE). According to LTE Release8 / 9...
