Techniques for sending assistance information for cancelling interference in wireless communications

An apparatus for wireless communication, comprising:

• a transceiver;
• one or more memories configured to, individually or in combination, store instructions;
• and
• one or more processors communicatively coupled with the one or more memories, wherein the one or more processors are, individually or in combination, configured to execute the instructions to cause the apparatus to:
• transmit, for a user equipment (UE), an indication of information used by the apparatus for transmitting downlink signals to one or more co-scheduled UEs scheduled with resources that are spatially multiplexed with resources scheduled for the UE, including at least one of a modulation and coding scheme (MCS) used for transmitting the downlink signals to the one or more co-scheduled UEs, a physical downlink shared channel (PDSCH) duration used for transmitting the downlink signals to the one or more co-scheduled UEs, a scrambling sequence used for transmitting the downlink signals to the one or more co-scheduled UEs, or a reference signal location used for transmitting the downlink signals to the one or more co-scheduled UEs;
• and
• transmit a downlink signal intended for the UE, wherein the downlink signal is interfered by one or more interference signals transmitted to the one or more co-scheduled UE.

A method for wireless communication at a user equipment (UE), comprising:

• receiving, from a network node, an indication of information used by the network node for transmitting downlink signals to one or more co-scheduled UEs scheduled with resources that are spatially multiplexed with resources scheduled for the UE, including at least one of a modulation and coding scheme (MCS) used for transmitting the downlink signals to the one or more co-scheduled UEs, a physical downlink shared channel (PDSCH) duration used for transmitting the downlink signals to the one or more co-scheduled UEs, a scrambling sequence used for transmitting the downlink signals to the one or more co-scheduled UEs, or a reference signal location used for transmitting the downlink signals to the one or more co-scheduled UEs;
• receiving, from the network node, a downlink signal intended for the UE, wherein the downlink signal is interfered by one or more interference signals transmitted to the one or more co-scheduled UE;
• and
• removing, based on the indication, the one or more interference signals from the downlink signal.
