1. A method for wireless communications at a user equipment (UE), comprising:
receiving, from a first transmission reception point and via a first carrier configured for the UE, a downlink control message that schedules a downlink signal on a second carrier for the UE;
determining a transmission scheme of a plurality of transmission schemes based at least on the first carrier, the second carrier, and a second transmission reception point scheduled for transmission of the downlink signal;
determining a delay between the downlink control message and the downlink signal based at least on the transmission scheme; and
receiving the downlink signal via the second carrier in accordance with the determined delay,
wherein determining the delay comprises:
(i) determining a first value for the delay based at least on the first and second transmission reception points being the same, and determining a second value for the delay based at least on the first and second transmission reception points being different, wherein the transmission scheme is a multiple transmission reception point scheme associated with the first transmission reception point and the second transmission reception point, the method further comprising determining the second value based at least on a multiplexing scheme associated with the multiple transmission reception point scheme; or
(ii) determining the first value for the delay based at least on the first and second carriers being the same, determining the second value for the delay based at least on the first and second carriers being different, determining a third value for the delay based at least on the first and second transmission reception points being the same, and determining a fourth value for the delay based at least on the first and second transmission reception points being different; or
(iii) determining the delay to be a value of one or more delay values indicated in a capability report, the method further comprising transmitting the capability report to the first transmission reception point indicating the one or more delay values for the UE, wherein each of the one or more delay values corresponds to a different transmission scheme of the plurality of transmission schemes.
