    Abstract: Embodiments of the present invention provide a data transmission method based on cross-carrier scheduling. The method includes: determining a first downlink subframe according to a timing relationship of an uplink HARQ of a reference uplink and downlink configuration, where the first downlink subframe is used to indicate timing of sending uplink scheduling grant information of a first uplink subframe of a scheduled cell; transmitting the uplink scheduling grant information in a subframe of a scheduling cell corresponding to the first downlink subframe, under a circumstance that the subframe of the scheduling cell corresponding to the first downlink subframe is a downlink subframe, where an uplink and downlink configuration of the scheduling cell and an uplink and downlink configuration of the scheduled cell are different; and receiving or sending uplink data in the first uplink subframe. In the present invention, the cross-carrier scheduling may be implemented effectively.

    Abstract: The application pertains to a method for communicating downlink control information. A base station maps an enhanced physical downlink control channel (E-PDCCH) sequentially to resource elements for transmitting the E-PDCCH in each orthogonal frequency division multiplexing (OFDM) symbol according to an order of OFDM symbols used by the E-PDCCH of a user equipment (UE). The E-PDCCH is sent to the UE from the base station by using the resource elements, where the E-PDCCH and a physical downlink shared channel (PDSCH) invoked by the E-PDCCH are frequency-division multiplexed. Because the E-PDCCH is mapped sequentially to resource elements for transmitting the E-PDCCH in each OFDM symbol according to an order of OFDM symbols used by the E-PDCCH of the UE, different control channel elements of E-PDCCHs at different aggregation levels will not include a same E-PDCCH modulation symbol, thereby ensuring that the UE judges a start position of the E-PDCCH correctly.

    Abstract: Embodiments of the present invention provide a method for implementing hybrid automatic repeat request, a user equipment, and a base station. The method includes: determining first indication information and second indication information separately according to feedback information of each downlink subframe of a primary cell and that of a secondary cell that need to be sent in a same uplink subframe of the primary cell, where the first indication information is used to indicate first feedback information of each downlink subframe of the primary cell that needs to be sent in the uplink subframe, and the second indication information is used to indicate second feedback information of each downlink subframe of the secondary cell that needs to be sent in the uplink subframe; sending mapping information of the first indication information and the second indication information in the uplink subframe.

    Abstract: The present invention provides a control channel modulation and demodulation method, a base station, and a user equipment. An effective coding rate that is at the time when a first modulation manner is used to modulate the control channel is determined according to a length of control information borne on a control channel and the number of resource elements occupied by the control channel. The control channel is modulated using a second modulation manner when the effective coding rate is greater than a first threshold.
