Abstract: Embodiments of this application disclose a multi-user pairing method and apparatus, and a base station. The method includes: obtaining an actual downlink channel parameter of user equipment UE at a moment t0; calculating a correlation coefficient between the actual downlink channel parameter at the moment t0 and an actual downlink channel parameter of the UE at a moment t0-Δt; determining a predicted downlink channel parameter of the UE at a moment t1 if the correlation coefficient is less than a preset threshold; and performing a multi-user pairing operation based on the predicted downlink channel parameter at the moment t1.

Abstract: This application provides example data dimension reduction methods, apparatus, and systems, computer devices, and storage mediums, and relates to the communications field. One example method includes receiving an antenna domain received signal, where the antenna domain received signal includes an uplink signal that is received from UE by an array antenna corresponding to an RRS, wherein the antenna domain received signal is a time domain signal, a dimension of the antenna domain received signal is N1, and N1 is an integer greater than 1. A received beam weight is obtained based on channel information of the UE. Dimension reduction is performed on the antenna domain received signal by using the received beam weight to obtain a beam domain received signal, where the beam domain received signal is a frequency domain signal, a dimension of the beam domain received signal is N2, and 0

Abstract: Embodiments of this application disclose a user pairing method and a related device. The method includes: first, determining a first generation parameter of a first base sequence of a first user and a second generation parameter of a second base sequence of a second user, and the second base sequence is used to generate a second uplink reference signal of the second user; then, determining multiplexing evaluation information based on the first generation parameter and the second generation parameter, where the multiplexing evaluation information may include correlation strength between sequences and interference leakage width; afterwards, determining, based on the multiplexing evaluation information, whether the first user and the second user are successfully paired. Finally, when the first user and the second user are successfully paired, it is determined that the first user and the second user multiplex a same communication resource for communication.
