Abstract: Embodiments of the present invention disclose a control information sending method, a control information detection method, a base station, and user equipment. The control information sending method includes: determining, by a base station, target control information and characteristic information corresponding to the target control information, where the target control information is information for scheduling target user equipment by the base station; determining, according to a preset rule and the characteristic information from a resource block set corresponding to a target coverage level, a target resource block subset corresponding to the target control information, and selecting, from the target resource block subset, an available resource block as a target resource block; and sending the target control information using the target resource block.

Abstract: A pilot signal transmission method, a channel estimation method, and an apparatus are provided, and the method for a pilot signal transmission includes: transmitting a pilot signal 1 CPICH1 over a first antenna, and transmitting a pilot signal 2 CPICH2 over a second antenna; transmitting a pilot signal CPICHk1 over a k1th antenna; and when it is determined that a terminal of a first category in the MIMO system is scheduled, transmitting a pilot signal CPICHk2 over the k1th antenna. Interference caused by a pilot signal to a traditional terminal is better reduced, performance of the traditional terminal is ensured while the terminal of the first category properly works in the MIMO system, and power consumption for transmitting a pilot signal is effectively reduced.
