Title:
METHOD AND APPARATUS FOR INTERFERENCE INDICATION IN COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/228076
Kind Code:
A1
Abstract:
The present application provides a method and apparatus for interference indication. The method comprises: a communication device receives first indication information; the communication device determines that a demodulation reference signal (DMRS) of an interference signal is related to a serving cell, and/or that the demodulation reference signal (DMRS) of the interference signal is related to a non-serving cell or a non-serving cell group. By means of the embodiments provided, a receiving end may determine an appropriate interference DMRS sequence scrambling parameter according to the first indication information, and further determine an accurate interference DMRS sequence, so that an interference channel may be estimated according to the accurate interference DMRS sequence, and an advanced receiver can perform interference cancellation or interference suppression.
