1. A method for processing a signal, comprising:
receiving, by a front end device of a base station system, a time-domain signal transmitted by an antenna element;
performing, by the front end device, multiple-input and multiple-output (MIMO) detection and related baseband processing on the time-domain signal; and
transmitting, by the front end device, the signal, on which the baseband processing is performed, to a backend device of the base station system;
wherein the method further comprises:
estimating, by the front end device, a channel, interference, and noise of a scheduled UE, and transmitting information about the estimated channel, interference, and noise to the backend device; and
performing, by the backend device, uplink scheduling, and determining an MIMO detection matrix of the scheduled UE, according to the estimation information, and transmitting uplink resource allocation scheme information and the MIMO detection matrix of the scheduled UE to the front end device.
