Network assisted interference cancellation signaling

摘要

Aspects of the present disclosure relate to techniques for network assisted interference cancellation (NAIC). An example method generally includes receiving network assisted interference cancellation (NAIC) information from a potentially interfering neighbor base station, and performing interference cancellation, suppression or mitigation when processing a signal from a serving base station using the NAIC information.

主权项

1. A method of wireless communications performed by a user equipment (UE), comprising:
receiving network assisted interference cancellation (NAIC) information from a potentially interfering neighbor base station, wherein receiving the NAIC information comprises decoding an enhanced physical downlink control channel (ePDCCH) of the neighbor base station, and wherein decoding the ePDCCH comprises rate matching, wherein the rate matching is dependent on at least one of:
a Radio Network Temporary Identifier (RNTI) associated with the ePDCCH, rate matching information mapped to an ePDCCH set including the ePDCCH, oran ePDCCH decoding candidate within an ePDCCH set, and wherein at least one of:
the UE is configured with two or more rate matching possibilities for a same ePDCCH decoding candidate; orthe UE is configured to use a first rate matching configuration for one or more ePDCCH decoding candidates for one cell and to use a second rate matching configuration for one or more other ePDCCH decoding candidates for another cell; and performing interference cancellation or suppression when processing a signal from a serving base station using the NAIC information.
