Abstract: The present invention provides a method for determining a rank indication (RI) bit number, a base station, and a terminal. The method includes: determining, by a base station, indication information according to a correspondence between a terminal and the base station and a multi-input multi-output (MIMO) capability of the terminal, where the indication information includes information used by the terminal for determining a bit number occupied for sending a RI; and sending, by the base station, the indication information to the terminal, so that the terminal determines, according to the indication information, the bit number occupied for sending the RI. In the present invention, the UE and the base station agree on understanding of the bit number occupied by RI information.

Abstract: Embodiments of the present invention provide a signal processing method and a terminal. The method includes: receiving a control signal. Channel state information between a coordinated base station and the terminal and between the serving base station and the terminal is determined. Information is about determined time difference or information about a phase difference of arrival between signals sent by the coordinated base station and the serving base station at the terminal according to the channel state information. Adjustment information is sent to the serving base station so that the serving base station adjusts the sending time, phase, or pre-coding manner of the signal according to the adjustment information.
