A method for wireless communication at a user equipment, UE (115; 705; 805; 1005), comprising: receiving (610; 1505; 1610; 1705) a first physical downlink control channel, PDCCH, message (215-a; 410-a) in a slot (210; 405), the first PDCCH message identifying physical downlink shared channel, PDSCH, resources (220; 415) within the slot to be monitored by the UE for data traffic; monitoring (620; 1510; 1615; 1710) for the data traffic in accordance with the first PDCCH message; identifying that the UE is to monitor the slot for an additional PDCCH message (215-b; 410-b) in accordance with a PDCCH monitoring configuration that indicates more than one PDCCH message monitoring occasions in non-consecutive symbols of the slot; receiving (625; 1515; 1620; 1715) the additional PDCCH message (215-b; 410-b) within the slot, the additional PDCCH message arriving after the UE has started monitoring for the data traffic, the additional PDCCH message including a downlink preemption indication (225; 440) indicating that at least a portion of the data traffic was preempted; identifying, using the downlink preemption indication, one or more symbols of a PDSCH message carrying the data traffic that correspond to the portion of the data traffic that was preempted; attempting (630; 1725) to decode the data traffic based at least in part on the identification of the one or more symbols of the PDSCH message that were preempted; and transmitting (635; 1520; 1625; 1730) a feedback message within the slot associated with receipt of the data traffic, wherein the feedback message indicates whether the data traffic was successfully decoded; identifying the one or more symbols of the PDSCH message that were preempted comprises mapping bits of the downlink preemption indication to symbols and frequency resources of the PDSCH message, wherein each bit of the downlink preemption indication maps to one symbol and a subband of the PDSCH resources (220; 415) or each bit of the downlink preemption indication maps to a resource region of multiple symbols and a subband of the PDSCH resources (220; 415); wherein the PDSCH message has a length shorter than the slot; and wherein the PDSCH resources include at least one subband within an active bandwidth part. receiving (610; 1505; 1610; 1705) a first physical downlink control channel, PDCCH, message (215-a; 410-a) in a slot (210; 405), the first PDCCH message identifying physical downlink shared channel, PDSCH, resources (220; 415) within the slot to be monitored by the UE for data traffic; monitoring (620; 1510; 1615; 1710) for the data traffic in accordance with the first PDCCH message; identifying that the UE is to monitor the slot for an additional PDCCH message (215-b; 410-b) in accordance with a PDCCH monitoring configuration that indicates more than one PDCCH message monitoring occasions in non-consecutive symbols of the slot; receiving (625; 1515; 1620; 1715) the additional PDCCH message (215-b; 410-b) within the slot, the additional PDCCH message arriving after the UE has started monitoring for the data traffic, the additional PDCCH message including a downlink preemption indication (225; 440) indicating that at least a portion of the data traffic was preempted; identifying, using the downlink preemption indication, one or more symbols of a PDSCH message carrying the data traffic that correspond to the portion of the data traffic that was preempted; attempting (630; 1725) to decode the data traffic based at least in part on the identification of the one or more symbols of the PDSCH message that were preempted; and transmitting (635; 1520; 1625; 1730) a feedback message within the slot associated with receipt of the data traffic, wherein the feedback message indicates whether the data traffic was successfully decoded; identifying the one or more symbols of the PDSCH message that were preempted comprises mapping bits of the downlink preemption indication to symbols and frequency resources of the PDSCH message, wherein each bit of the downlink preemption indication maps to one symbol and a subband of the PDSCH resources (220; 415) or each bit of the downlink preemption indication maps to a resource region of multiple symbols and a subband of the PDSCH resources (220; 415); wherein the PDSCH message has a length shorter than the slot; and wherein the PDSCH resources include at least one subband within an active bandwidth part.
