摘要： According to some embodiments, a method performed by a network node (115A) for providing interference mitigation assistance to a wireless device (110C) includes associating demodulation reference signal (DMRS) sequence information with at least one transmission parameter that applies to the DMRS sequence information. An indication of the association of the DRMS sequence information with the at least one transmission parameter is transmitted to the wireless device (110C) for use in performing mitigation of an interfering signal from a first transmission point (115A or 115B).

摘要： A method in a user equipment (605) is disclosed. The method comprises acquiring (704, 708) interference mitigation assistance parameters and granularity parameters, determining (712) one or more interfering cells (610B) for which a first strength measurement should be determined, determining (716) a first strength measurement for each of the determined one or more interfering cells, and ordering (720) the one or more interfering cells. The method further comprises identifying (724) from the ordered one or more interfering cells a first number of interfering cells having the strongest first strength measurements, determining (728) a second strength measurement for each of the identified first number of interfering cells, determining (732) one or more cells of the identified first number of interfering cells for which to perform cancellation of interference, and performing (736) cancellation of interference on the determined one or more cells of the identified first number of interfering cells.

摘要： In one aspect, a network node facilitates pilot sequence detection by a wireless device operating in a wireless communication network. The network node determines restriction information that indicates a reduction of a search space used by the wireless device for blind detection of pilot sequences from one or more interfering transmission points. Assistance data that includes the restriction information is generated. The assistance data is transmitted to the wireless device to reduce the search space used by the wireless device for the blind detection of pilot sequences according to the restriction information.
