Abstract:
A method is provided for assisting measurement of a user equipment (UE). The method is performed by a serving cell for the UE. The serving cell determines whether a cell-specific reference signal (CRS) of the serving cell is to collide with a CRS of a second neighbor cell or whether a CRS of a first neighbor cell is not to collide with the CRS of the second neighbor cell, if the serving cell and the first neighbor cell correspond to aggressor cells to the second neighbor cell corresponding to a victim cell. The serving cell generates a second measurement subframe pattern based on an almost blank subframe (ABS) pattern in response to the determination, and transmits the second measurement subframe pattern for the first and second neighbor cells to the UE.
Abstract:
One embodiment of the present specification discloses a method by which a serving cell transmits support information for removing interference of a terminal. The method comprises: a step for determining, by the serving cell, a downlink timing offset with neighboring interference cells; and a step for to determining, by the serving cell, a channel corresponding to an interference removal target among neighboring interference cells according to the timing offset. Here, the channel to have interference removed can be the channel interfering in a control channel for the serving cell according to the timing offset. The method further includes a step for enabling the serving cell to generate the interference removal support information on the determined channel and transmit the generated information to a terminal.
