Signaling to support advanced wireless receivers and related devices and methods

摘要

Various devices and methods are provided that use signaling to support advanced wireless receivers. For example, a method includes receiving an input signal at a user equipment. The input signal includes a desired signal and an interfering signal, where the desired signal defines symbols using constellations. The method also includes obtaining information identifying a wireless channel used by the interfering signal and a modulation type used to modulate data in the interfering signal. The method further includes recovering the symbols from the desired signal using the information.

主权项

1. An apparatus comprising:
at least one receiver configured to receive an input signal, the input signal comprising a desired signal transmitted from a base station and an interfering signal, the desired signal defining symbols using constellations and the interfering signal defining symbols using constellations; and at least one processing unit configured to:
receive a Precoding Matrix Indicator (PMI) or a predefined demodulation reference signal (DMRS) sequence of the interfering signal, the PMI or DMRS being transmitted by the base station, andblindly determine additional information including a type of symbol used in the interfering signal, wherein parameters associated with the additional information are stored in a memory coupled to the processing unit prior to receipt of the input signal, andjointly decode the symbols in the desired signal and the interfering signal using only the PMI or DMRS, and the additional information.
