The present invention provides a method and an apparatus for presenting a panoramic photo in a mobile terminal, and a mobile terminal. In the present invention, a trigger instruction that is used to instruct the mobile terminal to enter an immersive browsing mode is detected, where the immersive browsing mode is a browsing mode in which a panoramic photo moves as the mobile terminal rotates; and if the trigger instruction is detected, a rotation angle of the mobile terminal is detected and determined, and a panoramic photo that is presented in a normal mode in the mobile terminal is moved and presented according to the determined rotation angle. By using the present invention, complexity of panoramic photo browsing can be reduced, which makes it convenient for a user to browse a panoramic photo.

It is possible to improve the CQI reception performance even when a delay is caused in a propagation path, a transmission timing error is caused, or a residual interference is generated between cyclic shift amounts of different ZC sequences. For the second symbol and the sixth symbol of the ACK/NACK signal which are multiplexed by RS of CQI, (+, +) or (-, -) is applied to a partial sequence of the Walsh sequence. For RS of CQI transmitted from a mobile station, + is added as an RS phase of the second symbol and - is added as an RS phase of the sixth symbol. A base station (100) receives multiplexed signals of ACK/NACK signals and CQI signals transmitted from a plurality of mobile stations. An RS synthesis unit (119) performs synthesis by aligning the RS phase of CQI.
