Control information transmission method, user equipment, and base station

A control information transmission method, comprising:

• configuring a data channel transmission mode;
• determining a downlink control information DCI format set corresponding to the transmission mode, wherein the DCI format set comprises a first DCI format, and the first DCI format comprises single-codeword control information;
• and
• sending, according to the DCI format set, control signaling corresponding to the DCI format set to a user equipment.

A user equipment, comprising:

• a first obtaining module, adapted to obtain a data channel transmission mode configured by a base station;
• a first determining module, adapted to determine a downlink control information DCI format set corresponding to the transmission mode obtained by the first obtaining module, wherein the DCI format set comprises a first DCI format, and the first DCI format comprises single-codeword control information;
• and
• a detecting module, adapted to detect, according to the DCI format set determined by the first determining module, control signaling sent by the base station and corresponding to the DCI format set.

A base station, comprising:

• a configuring module, adapted to configure a data channel transmission mode;
• a first determining module, adapted to determine a downlink control information DCI format set corresponding to the transmission mode configured by the configuring module, wherein the DCI format set comprises a first DCI format, and the first DCI format comprises single-codeword control information;
• and
• a first sending module, adapted to send, according to the DCI format set determined by the first determining module, control signaling corresponding to the DCI format set to a user equipment.
