A method for wireless communication at a user equipment, UE, that supports half-duplex operation in dual connectivity, DC, wherein the UE is: a first type of UE configured to support the exchange of dynamic scheduling information between a first radio access technology, RAT, and a second RAT, or a second type of UE that is not configured to support the exchange of dynamic scheduling information between the first RAT and the second RAT, the method comprising: receiving (305, 310; 805; 905; 1005) a first slot format configuration for a first cell and a second slot format configuration for a second cell, the first cell being associated with the first RAT and a first radio frequency, RF, spectrum band and the second cell being associated with the second RAT and a second RF spectrum band; identifying (810; 910; 1010), for at least a portion of a transmission time interval, TTI,, a conflict between a first communication direction on the first RF spectrum band for the first cell and a second communication direction on the second RF spectrum band for the second cell; determining that the first cell has priority over the second cell; and determining (315; 815; 915; 1015), in response to the identified conflict, whether to drop a transmission on the second cell in the second communication direction, wherein when the first RAT is new radio, NR, determining whether to drop the transmission on the second cell in the second communication direction is based on whether the UE is a first type of UE or a second type of LTE, and wherein when the first RAT is long-term evolution, LTE, determining whether to drop the transmission on the second cell in the second communication direction is not based on the type of LTE. a first type of UE configured to support the exchange of dynamic scheduling information between a first radio access technology, RAT, and a second RAT, or a second type of UE that is not configured to support the exchange of dynamic scheduling information between the first RAT and the second RAT, the method comprising: receiving (305, 310; 805; 905; 1005) a first slot format configuration for a first cell and a second slot format configuration for a second cell, the first cell being associated with the first RAT and a first radio frequency, RF, spectrum band and the second cell being associated with the second RAT and a second RF spectrum band; identifying (810; 910; 1010), for at least a portion of a transmission time interval, TTI,, a conflict between a first communication direction on the first RF spectrum band for the first cell and a second communication direction on the second RF spectrum band for the second cell; determining that the first cell has priority over the second cell; and determining (315; 815; 915; 1015), in response to the identified conflict, whether to drop a transmission on the second cell in the second communication direction, wherein when the first RAT is new radio, NR, determining whether to drop the transmission on the second cell in the second communication direction is based on whether the UE is a first type of UE or a second type of LTE, and wherein when the first RAT is long-term evolution, LTE, determining whether to drop the transmission on the second cell in the second communication direction is not based on the type of LTE. receiving (305, 310; 805; 905; 1005) a first slot format configuration for a first cell and a second slot format configuration for a second cell, the first cell being associated with the first RAT and a first radio frequency, RF, spectrum band and the second cell being associated with the second RAT and a second RF spectrum band; identifying (810; 910; 1010), for at least a portion of a transmission time interval, TTI,, a conflict between a first communication direction on the first RF spectrum band for the first cell and a second communication direction on the second RF spectrum band for the second cell; determining that the first cell has priority over the second cell; and determining (315; 815; 915; 1015), in response to the identified conflict, whether to drop a transmission on the second cell in the second communication direction, wherein when the first RAT is new radio, NR, determining whether to drop the transmission on the second cell in the second communication direction is based on whether the UE is a first type of UE or a second type of LTE, and wherein when the first RAT is long-term evolution, LTE, determining whether to drop the transmission on the second cell in the second communication direction is not based on the type of LTE.
