1. A method, comprising:
- determining, by user equipment, whether a feedback manner of a hybrid automatic repeat request-acknowledgment (HARQ-ACK) corresponding to a first serving cell is transmitted via a control channel associated with a second serving cell, wherein the first serving cell is a serving cell corresponding to the user equipment, the second serving cell is a serving cell that corresponds to the user equipment, and the second serving cell uses a duplex mode other than the duplex mode used by the first serving cell;
determining, by the user equipment, a downlink control information (DCI) format of a downlink control channel corresponding to a first serving cell, wherein the DCI format is determined according to a duplex mode of the first serving cell and the feedback manner of the HARQ-ACK corresponding to the first serving cell; and
detecting, by the user equipment, the downlink control channel according to the determined DCI format.

Abstract
Embodiments relate to a control information transmission method, user equipment, and a base station. The control information transmission method includes: determining, by user equipment, a downlink control information (DCI) format of a downlink control channel corresponding to a first serving cell, where the first serving cell is a serving cell corresponding to the user equipment, and the DCI format is determined using a duplex mode of the first serving cell and a feedback manner of a hybrid automatic repeat request-acknowledgment (HARQ-ACK) corresponding to the first serving cell; and detecting, by the user equipment, the downlink control channel according to the determined DCI format.

6. A method, comprising:
-
determining, by a base station, whether a feedback manner of a hybrid automatic repeat request-acknowledgment (HARQ-ACK) corresponding to a first serving cell is transmitted via a control channel associated with a second serving cell, wherein the first serving cell is a serving cell corresponding to user equipment, the second serving cell is a further serving cell corresponding to the user equipment, and the second serving cell uses a duplex mode other than the duplex mode used by the first serving cell; determining, by a base station, a downlink control information (DCI) format of a downlink control channel corresponding to a first serving cell, wherein the DCI format is determined according to a duplex mode of the first serving cell and the feedback manner of the HARQ-ACK corresponding to the first serving cell; and sending, by the base station, the downlink control channel according to the determined DCI format. - View Dependent Claims (7, 8, 9)

10. User equipment, comprising:
-
a processor; and a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for; whether a feedback manner of a hybrid automatic repeat request-acknowledgment (HARQ-ACK) corresponding to a first serving cell is transmitted via a control channel associated with a second serving cell, wherein the first serving cell is a serving cell corresponding to the user equipment, the second serving cell is a serving cell that corresponds to the user equipment, and the second serving cell uses a duplex mode other than the duplex mode used by the first serving cell; determining a downlink control information (DCI) format of a downlink control channel corresponding to a first serving cell, wherein the DCI format is determined according to a duplex mode of the first serving cell and the feedback manner of the HARQ-ACK corresponding to the first serving cell; and detecting the downlink control channel according to the determined DCI format. - View Dependent Claims (11, 12, 13, 14)

15. A base station, comprising:
-
a processor; a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for; determining whether a feedback manner of a hybrid automatic repeat request-acknowledgment (HARQ-ACK) corresponding to a first serving cell is transmitted via a control channel associated with a second serving cell, wherein the first serving cell is a serving cell corresponding to user equipment, the second serving cell is a further serving cell corresponding to the user equipment, and the second serving cell uses a duplex mode other than the duplex mode used by the first serving cell; determining, according to a duplex mode of a first serving cell and the feedback manner of the HARQ-ACK corresponding to the first serving cell, a downlink control information (DCI) format of a downlink control channel corresponding to the first serving cell; and a transmitter, configured to send the downlink control channel according to the determined DCI format. - View Dependent Claims (16, 17, 18)
