Abstract: This application provides an uplink control information transmission method. In a scenario in which uplink preemption occurs, the hybrid automatic repeat request (HARQ) acknowledgement information is transmitted on a physical uplink control channel (PUCCH) resource pre-configured at a higher signaling layer. In some embodiments, when the first uplink resource is a PUCCH resource used after the HARQ acknowledgement information is multiplexed or a physical uplink shared channel (PUSCH) resource used after the HARQ acknowledgement information is multiplexed, the HARQ acknowledgement information may be sent on the PUCCH resource that is used before the HARQ acknowledgement information is multiplexed, if the PUCCH resource is available. In some embodiments, when the first uplink resource is a PUSCH resource that is used after the HARQ acknowledgement information is multiplexed, a resource area in which a PUSCH is not occupied may be searched for a new PUCCH resource.

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.
