Some wireless communications systems may support different types of communications between base stations and user equipment (UEs), such as mobile broadband (MBB) communications and low latency communications. Low latency communications may be associated with bursty and unpredictable transmissions. As described herein, to facilitate low latency communications and limit the latency associated with waiting on appropriate resources for transmitting low latency data, a base station may schedule downlink low latency transmissions on uplink resources or uplink low latency transmissions on downlink resources. Further, to limit the latency associated with scheduling low latency communications, a base station may be configured with a carrier for transmitting preemption indications (PIs) to one or more UEs to reassign resources for low latency communications. Similarly, in some cases, a UE may be configured with a carrier to transmit scheduling requests (SRs) to request resources for low latency communications.
