Ultra-reliable low-latency communication indication channelization designs

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

• monitoring for a preemption indication based on a downlink configuration, the downlink configuration indicating how granular the preemption indication identifies preemption in a data space in terms of resources that are configurable at different granularities;
• receiving, from a base station at a first time on shared downlink resources, a data transmission comprising first data associated with a first type of wireless communication;
• receiving, from the base station at a second time subsequent to the first time, the preemption indication in a group common physical downlink control channel (PDCCH);
• determining, based on the preemption indication, whether at least a portion of the shared downlink resources occupied by the first data is preempted for use by the UE, the preemption comprising second data associated with a second type of wireless communication different from the first type of wireless communication puncturing resources occupied by the first data within the data transmission;
• and
• decoding the first data when the at least a portion of the shared downlink resources is not preempted by the second data.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a memory;
• a transceiver;
• and
• at least one processor coupled to the memory and the transceiver, the at least one processor being configured to execute instructions stored on the memory that cause the UE to:
• monitor for a preemption indication based on a downlink configuration, the downlink configuration indicating how granular the preemption indication identifies preemption in a data space in terms of resources that are configurable at different granularities;
• receive, from a base station at a first time on shared downlink resources, via the transceiver, a data transmission comprising first data associated with a first type of wireless communication;
• receive, from the base station at a second time subsequent to the first time, via the transceiver, the preemption indication in a group common physical downlink control channel (PDCCH);
• determine, based on the preemption indication, whether at least a portion of the shared downlink resources occupied by the first data is preempted for use by the UE, the preemption comprising second data associated with a second type of wireless communication different from the first type of wireless communication puncturing resources occupied by the first data within the data transmission;
• and
• decode the first data when the at least a portion of the shared downlink resources is not preempted by the second data.

A method of wireless communication at a base station, the method comprising:

• transmitting, to one or more user equipment (UE), a downlink configuration that indicates how granular a preemption indication identifies preemption in a data space in terms of resources that are configurable at different granularities;
• transmitting, to the one or more UEs at a first time on shared downlink resources, a data transmission comprising first data associated with a first type of wireless communication;
• and
• transmitting, to the one or more UEs at a second time subsequent to the first time, the preemption indication in a group common physical downlink control channel (PDCCH), wherein the preemption indication indicates whether at least a portion of the shared downlink resources occupied by the first data is preempted for use by the UE, the preemption comprising second data associated with a second type of wireless communication different from the first type of wireless communication puncturing resources occupied by the first data within the data transmission.

An apparatus for wireless communication at a base station, comprising:

• a transceiver;
• and
• at least one processor coupled to the memory and the transceiver, the at least one processor being configured to execute instructions stored on the memory that cause the base station to:
• transmit, to one or more user equipment (UEs), via the transceiver, a downlink configuration that indicates how granular a preemption indication identifies preemption in a data space in terms of resources that are configurable at different granularities;
• transmit, to the one or more UEs at a first time on shared downlink resources, via the transceiver, a data transmission comprising first data associated with a first type of wireless communication;
