Abstract
Methods, systems, and devices for wireless communications are described. An uplink preemption indication (PI) may be transmitted from a serving cell to a user equipment (UE), where the uplink PI indicates that uplink traffic is to be preempted. In some cases, the UE may communicate with the serving cell on a first component carrier (CC) according to a first time division duplexing (TDD) configuration, where the first TDD configuration includes uplink and downlink portions. The serving cell may transmit the uplink PI on a second CC, and the UE may monitor for and receive the uplink PI during downlink portions of the second CC during uplink portions of the first CC. In some cases, the UE may monitor the second CC in accordance with a frequency division duplexing (FDD) configuration. Additionally or alternatively, the UE may monitor the second CC in accordance with a second complementary TDD configuration.
