Abstract: Embodiments of this application disclose a cross-standard scheduling method and a base station, used for unified scheduling of UEs in different standards by using a unified scheduler, to achieve space division multiplexing of a spectrum resource, where different standards may share the spectrum resource. A unified scheduler is disposed in the base station in the embodiments of this application. The method and the base station may obtain downlink channel information of UEs operating using different standards and in overlapping coverage range. The method and the base station may determine a scheduling result using the unified scheduler based on the obtained downlink channel information of the UEs. The method and the base station may schedule the UEs based on the scheduling result.

Abstract: A signal transmission method includes: processing, by a base station, a first baseband signal, a second baseband signal, a third baseband signal, and a fourth baseband signal by using a VAM matrix, to obtain four processed signals; performing precoding processing on the four processed signals to obtain four coded signals; and sending the four coded signals to a mobile terminal by using four radio frequency ports. The four radio frequency ports are in a one-to-one correspondence with the four coded signals. A first processed signal is the same as a third processed signal, a second processed signal is the same as a fourth processed signal. The first processed signal is obtained by performing superposition on the first baseband signal and the third baseband signal, and the second processed signal is obtained by performing superposition on the second baseband signal and the fourth baseband signal.

Abstract: The present disclosure relates to the field of wireless technologies, and specifically, to remote radio unit channel transmit power setting. The disclosure describes example remote radio unit (RRU) channel transmit power setting methods and base stations. In one example, a first base station transmits signals to first user equipment (UE) at a first power by respectively using a first channel and a second channel of an RRU, and transmits signals to the UE at a second power by respectively using a third channel and a fourth channel of the RRU.
