Abstract: A method and an apparatus for determining a scheduling user and a system. The method includes: determining a first pre-scheduling user at a second moment from a user in the first cell at a first moment; determining a first transmit weight of the first cell at the second moment; receiving a second transmit weight at the second moment that is sent by a second base station to which a second cell belongs in a data transmission system; calculating a signal to interference plus noise ratio SINR of each user in the first cell at the second moment based on the first transmit weight and the second transmit weight; and selecting a target scheduling user at the second moment from the user in the first cell based on the SINR of each user at the second moment.

Abstract: Embodiments of this application disclose a communication method, and a related device and system. The method includes: receiving, by a reception point, first indication information, where the first indication information is used to indicate a time-frequency resource location of a first demodulation reference signal of first data; receiving, by the reception point, second indication information, where the second indication information is used to indicate a time-frequency resource location of a second demodulation reference signal; and determining, by the reception point, a time-frequency resource location of the first data based on the time-frequency resource location of the second demodulation reference signal, and demodulating the first data based on the first demodulation reference signal. Receiving performance of the reception point can be improved. On the premise that a resource conflict does not occur, two base stations communicate with a terminal device by using a time-frequency resource allocated by a second base station.

Abstract: Embodiments of the present invention relate to a signal sending method, a signal receiving method, a base station, and user equipment. The method includes: determining, by a base station based on receiver capabilities of user equipments, that first user equipment is to be paired with N second user equipments on a first resource block, where N is a positive integer; and multiplexing, by the base station, a signal of the first user equipment and signals of the N second user equipments onto the first resource block, and sending the signals. It can be learned from the foregoing that according to the embodiments of the present invention, not only channel quality of weak-receiver-capability user equipment is ensured, but also channel quality of strong-receiver-capability user equipment is maintained by using an excellent interference suppression capability of the strong-receiver-capability user equipment.
