Title: (EN) Method and apparatus for reducing the interferences between a wide band device and a narrow band interferer
(ZH) 降低宽带设备和窄带干扰源之间干扰的方法和装置
Abstract: front page image
(EN) The method comprises a main interference reduction mode (MIRM) for reducing interferences generated by a wide band device towards a narrow band device. Said method is performed within said wide band device and detecting (40) an emission from and/or a reception performed by said narrow baand device, determining (41) from said detection step a group of at least one sub-carrier having frequencies interfering with the narrow band device determining (42) the bits which correspond to the information carried by said interfering sub-carriers of said group and processing (43) said determined bits such that they are mapped into a reference symbol having an amplitude equal or close to zero.
(ZH)

一种用于降低由宽带设备对窄带设备产生的干扰的方法包括主干扰降低模式(MIRM),该方法在所述宽带设备内执行并包括检测由所述窄带设备执行的发射和/或接收(40),根据所述检测步骤确定具有至少一个子载波的子载波组(41),所述子载波具有干扰窄带设备的频率,确定相应于由所述干扰子载波组的所述干扰子载波所携带信息的比特(42),并且处理所述已确定比特以使得所述已处理比特映射为参考码元(43),所述参考码元具有等于或接近于零的幅度。
