Abstract: Embodiments of the present disclosure provide a method, device, radio network controller and chip for improving network quality. A signal of a user in a serving cell, detected by the same-frequency cell adjacent to the serving cell, is combined with a signal detected by the serving cell using a MCJD technology, so as to improve the signal quality of the user in the serving cell. The method of the present disclosure comprises: obtaining a first signal which belongs to a user terminal of a first cell and is detected by a base station of at least one second cell; combining the first signal with a second signal of the user terminal detected by a base station of the first cell to obtain a third signal; sending the third signal to a radio network controller. Therefore, the signal quality of the user in the first cell can be improved.

Abstract: A method for sending data includes obtaining data packets to be sent and modulating, by each transmit diversity branch, the data packets by using modulation mode corresponding to the each transmit diversity branch, and sending the modulated data packets. The modulation modes form a preset optimized combination of modulation modes. A different modulation mode corresponds to a different group of modulation factors and/or different group of constellation modulation symbols. The different groups of modulation factors comply with a preset modulation factor mapping relationship. The different groups of constellation modulation symbols comply with a preset constellation modulation symbol mapping relationship.
