Patent ID: 7978624

Claim:
A method for suppressing cross-slot interference in a time-slotted Code Division Multiple Access, CDMA, system, comprising: obtaining, by a base station, configuration information of a local cell and configuration information of co-frequency adjacent cells; wherein, the configuration information comprises time slot configuration information; determining, by the base station, positions of cross slots according to the configuration information of the local cell and the configuration information of the co-frequency adjacent cells, and performing multi-cell channel estimation on the cross slots to obtain channel estimation result; determining, by the base station, code channel configuration information of the co-frequency adjacent cells, grouping determined code channels and determining code channels of the co-frequency adjacent cells involved in a joint detection; and performing, by the base station, the joint detection according to the channel estimation result and determined code channels of the co-frequency adjacent cells involved in the joint detection to obtain detection data, so that the cross-slot interference in the system is suppressed without rearranging time slot configuration information of the local cell and the adjacent cells or eliminating any cross slots.
