    Abstract: A first unit for use in a base station in a mobile telecommunication network is adapted to use an identity for identifying a mobile terminal or for identifying a channel in the uplink. The first unit manages information of at least one additional identity of a mobile terminal or a channel belonging to at least a second base station for interference mitigation purposes. The first unit detects whether the mobile terminal or channel identified by the additional identity is active and mitigates cell-interference caused by an active mobile terminal or a channel identified by the additional identity. A second unit reserves at least one identity for identifying a mobile terminal or for identifying a channel in order to make the at least one identity identifiable to at least a second base station.

    Abstract: The present invention discloses a method for suppressing cross-slot interference in a time-slotted CDMA system. The method includes: determining, by a base station, positions of cross slots according to configuration information of local cell and configuration information of co-frequency adjacent cells, and performing multi-cell channel estimation on the cross slots to obtain channel estimation results; determining, by the base station, code channel configuration information of the co-frequency adjacent cells, grouping the determined code channels and determining the 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 multi-cell information estimation results and the determined code channels of the base stations involved in the joint detection to obtain detection data. With the present invention, interference from a base station transmitting downlink signals in cross slots to a base station receiving uplink signals in the corresponding slot may be reduced, and the system capacity and the stability may be improved.

    Abstract translation: 本发明公开了一种用于抑制时隙CDMA系统中的跨时隙干扰的方法。 该方法包括：基站根据本小区的配置信息和同频邻区的配置信息确定跨时隙的位置，并对跨时隙进行多小区信道估计，得到信道估计结果; 基站确定同频邻小区的码道配置信息，对确定的码道进行分组，并确定参与联合检测的同频邻小区的码道; 所述基站根据所述多小区信息估计结果和所述联合检测中涉及的基站的码道确定的联合检测得到检测数据。 通过本发明，可以减少在相应时隙中发送跨时隙中的下行链路信号的基站对接收上行链路信号的基站的干扰，并且可以提高系统容量和稳定性。
