Abstract: Embodiments of the present invention provide a coordinated multipoint reception processing method and apparatus, and a base station. The method includes: performing demodulating and decoding an uplink signal received by k collaboration sets of M collaboration sets, to obtain k cyclic redundancy check CRC results, where the uplink signal is sent by a user equipment UE, the collaboration set is a serving sector where the UE is located or a set formed by the serving sector and any one or more collaborative sectors, M≧2, and 1≦k≦M; and if the k CRC results include at least one correct CRC result, performing processing on a signal obtained by a CRC result of the at least one correct CRC result. According to the embodiments of the present invention, in a base station, detection performance is improved under actual channel estimation.

Abstract: Embodiments of the present invention provide a signal transmission method, apparatus, and base station. The method includes: sending downlink signals through N sectors, where the N sectors are created by using M sectors used to receive uplink signals, and N>M. In the embodiments of the present invention, the base station creates N sectors by using M sectors used to receive uplink signals and sends downlink signals through the N sectors, so that the multi-sector technology is mainly used in the downlink and the multi-antenna technology is mainly used in the uplink. This may resolve an existing conflict between the uplink and the downlink when system capacity is being improved, thereby improving system capacity of a wireless communication network.
