Abstract: Embodiments of the present invention provide a method and an apparatus for transmitting broadcast-multicast single-frequency network measurement data, where second measurement data is acquired by preprocessing acquired first measurement data, and the second measurement data is sent to a base station. Because the second measurement data is obtained after the first measurement data is preprocessed, a size of the second measurement data is smaller than that of the first measurement data, thereby reducing a transmission overhead.

Abstract: The present invention provides a method for determining an uplink transmission power and a user equipment. In the present invention, a user equipment determines an overlap between an uplink channel of a cell in a current subframe and an uplink channel of another cell in an adjacent subframe, the cell being carrier aggregation with the another cell, so that the user equipment can determine transmission power of a PUSCH of the cell in the current subframe and the another cell in the current subframe, the another cell being carrier aggregation with the cell. As a result, the problem that the uplink power control performed by the user equipment according to the prior art is not accurate is solved and thus the uplink data transmitting quality is improved.
