Abstract: A method of interference cancellation is proposed. A serving base station transmits a first configuration information to a UE, the first configuration information is related to a desired signal of a data transmission from a serving cell to the UE. The serving base station determines a second configuration information related to an interference signal of a data transmission from a neighboring cell to the UE. The second configuration information comprises a resource allocation type and a basic resource allocation unit of the interference signal. The serving base station transmits the second configuration information to the UE such that the UE can cancel the data transmission from the neighboring cell.

Abstract: A method of interference cancellation is proposed. A UE obtains configuration information of a data transmission from a neighboring cell via an interference channel in a mobile communication network. The UE receives radio signals on a set of data resource elements as determined based on the obtained configuration information. The UE then estimates the interference channel corresponding to the data transmission from the neighboring cell based on the received radio signals on the set of data resource elements. Finally, the UE cancels the data transmission from the neighboring cell based on the estimated interference channel.

Abstract: A method for a receiver to cancel or suppress co-channel interference with network assistance is provided. The method comprises deriving a first set of parameters related to interfering signals in a mobile communication network; receiving a second set of parameters related to the interfering signals from the network; and cancelling the contribution of interfering signals from the received signal based on the combination of the first set and second set of parameters. In one embodiment, the interfering signals comprise intra-cell interfering signals and/or inter-cell interfering signals. While inter-cell interference comes from neighboring cells, intra-cell interference comes from MU-MIMO transmission to other users in the same serving cell as the victim UE. In one example, the serving base station not only signals information to the victim UE for inter-cell interference, but also for intra-cell interference due to MU-MIMO transmission.
