Signaling of Network-Assisted Intra-Cell Interference Cancellation and Suppression

摘要

Signaling methods to support robust interference cancellation by obtaining information associated with interfering signals from the network side are provided. The target interference for cancellation is intra-cell interference from MU-MIMO or NOMA operation. A victim receiver receives both desired signal and intra-cell interfering signal. The network may assist the victim receiver by providing information related to the interfering signal. The computational complexity of the victim receiver in blindly detecting the interference signal characteristics is reduced, and the reliability of the signal detection is improved.

1. A method, comprising:
allocating a time-frequency radio resource to a first user equipment (UE) and a second co-channel user equipment (UE) by a serving base station (BS) in a serving cell of a mobile communication network; determining a set of parameters related to signals present in the allocated time-frequency radio resource, wherein the set of parameters comprises parameters related to a first signal and a second signal dedicated to the first UE and the second UE respectively; and transmitting the set of parameters to the second UE for the second UE to cancel/suppress a contribution of the first signal as an intra-cell interfering signal.
