1. A method for wireless communication, the method comprising:
- transmitting, from a first device, a reference signal to a second device during a first transmission time interval (TTI) of a carrier component;
receiving, at the first device, an indication of an interference pattern experienced by the second device for a duration of the first TTI, the indication being based on the reference signal;
receiving, at the first device, a request for mission-critical (MiCri) data; and
transmitting, from the first device, the MiCri data to the second device during the first TTI of the carrier component using a hybrid automated repeat request (HARM) block based on the indication and a determination that a remaining time period within the first TTI after receiving the request does not exceed a predetermined threshold.

Abstract
Systems and methods for communicating mission-critical (MiCri) data in a network including a base station and user equipment (UE) are provided. The methods may include receiving a request message requesting MiCri data, and transmitting the MiCri data during a transmission time interval (TTI) of a first carrier component or during a transmission time interval (TTI) of a second carrier component. In various aspects, the TTI of the first carrier component may be staggered in time with respect to the TTI of the second carrier component. In another aspect, the UE may pre-report interference pattern information for a nominal TTI for use in communication of MiCri data.

10. A method for wireless communication, the method comprising:
-
receiving, from a first device at a second device, a reference signal during a first transmission time interval (TTI) of a carrier component; transmitting, from the second device, an indication of an interference pattern experienced by the second device based on the reference signal; transmitting, from the second device, a request for mission-critical (MiCri) data; and receiving, at the second device, the MiCri data from the first device during the first TTI of the carrier component using a hybrid automated repeat request (HARQ) block based on the indication and a determination that a remaining time period within the first TTI after transmitting the request does not exceed a predetermined threshold. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A base station, comprising:
-
a transmitter configured to transmit a reference signal to a first device during a first transmission time interval (TTI) of a carrier component; and a receiver configured to; receive an indication of an interference pattern experienced by the first device for a duration of the first TTI, the indication being based on the reference signal; and receive a request for mission-critical (MiCri) data, wherein the transmitter is configured to transmit the MiCri data to the first device during the first TTI of the carrier component using a hybrid automated repeat request (HARQ) block based on the indication and a determination that a remaining time period within the first TTI after receiving the request does not exceed a predetermined threshold. - View Dependent Claims (20, 21, 22, 23, 24)

25. A user equipment (UE), comprising:
-
a receiver configured to receive a reference signal from a first device during a first transmission time interval (TTI) of a carrier component; and a transmitter configured to; transmit an indication of an interference pattern experienced by the UE based on the reference signal; and transmit a request for mission-critical (MiCri) data, wherein the receiver is configured to receive the MiCri data from the first device during the first TTI of the carrier component using a single hybrid automated repeat request (HARQ) block based on the indication and a determination that a remaining time period within the first TTI after transmitting the request does not exceed a predetermined threshold. - View Dependent Claims (26, 27, 28, 29, 30)
