Schemes for recovery of eMBB's RS puncturing from dynamic multiplexing of URLLC/eMBB

An apparatus for wireless communications, comprising:

• a memory having stored instructions;
• and
• a processor in communication with the memory;
• wherein the processor is configured to execute the instructions to:
• identify, at a base station, at least one scheme supported by the base station for handling puncturing of reference signal (RS) symbols in enhanced mobile broadband (eMBB) traffic by ultra-reliable-low-latency communications (URLLC) traffic, wherein each of the at least one scheme modifies an existing RS pattern configured for the eMBB traffic before puncturing occurs in response to a presence of the URLLC traffic, wherein the at least one scheme includes a block-based scheme in which RS symbols within a slot for the eMBB traffic are spread apart for potential puncturing by the URLLC traffic to occur on data symbols between the RS symbols;
• and
• perform, at the base station, the at least one scheme in connection with downlink transmissions.

An apparatus for wireless communications, comprising:

• a memory having stored instructions;
• and
• a processor in communication with the memory;
• wherein the processor is configured to execute the instructions to:
• receive, at a user equipment (UE), an indication of at least one scheme for handling puncturing of reference signal (RS) symbols in enhanced mobile broadband (eMBB) traffic by ultra-reliable-low-latency communications (URLLC) traffic, wherein each of the at least one scheme modifies an existing RS pattern configured for the eMBB traffic before puncturing occurs in response to a presence of the URLLC traffic, wherein the at least one scheme includes a block-based scheme in which RS symbols within a slot for the eMBB traffic are spread apart for potential puncturing by the URLLC traffic to occur on data symbols between the RS symbols;
• and
• perform, at the UE, the at least one scheme in connection with downlink transmissions.
