Using blanked multicast broadcast single frequency network (MBSFN) subframes for mitigating interference in a wireless communication system

摘要

A method and apparatus of mitigating interference in a wireless communication network (100) is described, the method comprising reserving (1312) a subframe by a first base station (110a-c) for a second base station (110a-c), sending (1316) a reference signal in a first part of the reserved subframe in accordance with a multicast/broadcast single frequency network, MBSFN, subframe format and sending (1318) no transmissions or transmissions at a low transmit power level in a remaining part of the reserved subframe to reduce interference to stations served by the second base station (110a-c). Also a method an apparatus for the corresponding reserved base stations is described.
