Problems solved by technology

But so-called "blind detection" receivers can be complex and unreliable if it has to detect or estimate all characteristics that may interfere with data transmission, especially in LTE when the resources allocated for data transmission are dynamic in both time and frequency dimensions

Embodiment Construction

[0025] Reference will now be made in detail to some embodiments of the invention, and examples of the invention will be described with reference to the accompanying drawings.

[0026] figure 1 Is a schematic diagram of a mobile communication network 100 with interference cancellation for data transmissions from neighboring cells according to one novel aspect. The mobile communication network 100 is an OFDM network, including multiple user equipments, a serving base station eNB104 and a neighboring base station eNB105, wherein the multiple user equipments are UE101, UE102 and UE103. exist figure 1 In the example of , UE101 is served by its serving base station eNB104. UE101 receives desired wireless signal 111 which has been transmitted from ENB104. However, UE 101 also receives interfering wireless signals. In one example, UE 101 receives an intra-cell interfering wireless signal 112 from the same serving ENB 104 . Typically, such intra-cell interference is due to Multi...

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.
