Methods and apparatuses for indication of transmission preemption based on a hybrid automatic repeat request configuration

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

• a memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors to:
• receive, at a first location in a downlink signal, preemption information that identifies a second location of a first type of traffic that preempts a second type of traffic, the first location relative to the second location being based at least in part on a hybrid automatic repeat request (HARQ) configuration of the UE, the HARQ configuration indicating a configuration to perform a HARQ response, associated with the second type of traffic, within a quantity of HARQ interlaces that cause the UE to provide the HARQ response in a subsequent slot after a first slot in which the second type of traffic is received, the quantity of HARQ interlaces being two or more interlaces, and the first type of traffic being scheduled to be received in the first slot;
• receive the first type of traffic at the second location;
• generate the HARQ response;
• and
• transmit the HARQ response based at least in part on the HARQ configuration of the UE.

A method of wireless communication for a base station, comprising:

• determining a hybrid automatic repeat request (HARQ) configuration of user equipment (a UE);
• providing, at a first location in a downlink signal, preemption information that identifies a second location of a first type of traffic that preempts a second type of traffic, the first location relative to the second location being based at least in part on the HARQ configuration;
• providing the first type of traffic at the second location;
• receiving a HARQ response associated with the first type of traffic, the HARQ configuration indicating a configuration to perform a HARQ response, associated with the second type of traffic, within a quantity of HARQ interlaces that cause the UE to provide the HARQ response in a subsequent slot after a first slot in which the second type of traffic is received, the quantity of HARQ interlaces being two or more interlaces, and the first type of traffic being scheduled to be received in the first slot;
• and
• transmitting the second type of traffic based at least in part on the HARQ response.

A base station for wireless communication, comprising:

• a memory;
• and
• at least one processor operatively coupled to the memory, the memory and the at least one processor configured to:
• determine a hybrid automatic repeat request (HARQ) configuration of user equipment (a UE);
• provide, at a first location in a downlink signal, preemption information that identifies a second location of a first type of traffic that preempts a second type of traffic, the first location relative to the second location being based at least in part on the HARQ configuration;
• provide the first type of traffic at the second location;
• receive a HARQ response associated with the first type of traffic, the HARQ configuration indicating a configuration to perform a HARQ response, associated with the second type of traffic, within a quantity of HARQ interlaces that cause the UE to provide the HARQ response in a subsequent slot after a first slot in which the second type of traffic is received, the quantity of HARQ interlaces being two or more interlaces, and the first type of traffic being scheduled to be received in the first slot;
• and
• transmit the second type of traffic based at least in part on the HARQ response.
