A method of wireless communication performed by a user equipment, UE, comprising: receiving (710, 720; 810) a set of indicators indicating that a first transmission is scheduled for concurrent transmission with a second transmission, wherein the UE is not configured to transmit the first transmission and the second transmission concurrently; selecting (730; 820) one of the first transmission or the second transmission for transmission based at least in part on a characteristic of at least one of the first transmission or the second transmission identified using the set of indicators; and transmitting (740; 830) the selected one of the first transmission or the second transmission based at least in part on selecting the one of the first transmission or the second transmission, wherein the first transmission is a physical uplink shared channel, PUSCH, transmission scheduled by a preconfigured uplink grant from a base station and the second transmission is a PUSCH transmission scheduled by a dynamic uplink grant from the base station; characterized in that the characteristic comprises a first radio network temporary identifier, RNTI, used to indicate a first modulation and coding scheme, MCS, to be used for the first transmission, wherein the preconfigured uplink grant is scrambled using the first RNTI; and wherein selecting (730; 820) one of the first transmission or the second transmission based at least in part on the characteristic comprises: selecting the first transmission when the first RNTI indicates that the first transmission is to use a high-reliability MCS satisfying a reliability requirement for a ultra reliable low latency communications, URLLC, service; and selecting the second transmission when the first RNTI indicates that the first transmission is not to use the high-reliability MCS. receiving (710, 720; 810) a set of indicators indicating that a first transmission is scheduled for concurrent transmission with a second transmission, wherein the UE is not configured to transmit the first transmission and the second transmission concurrently; selecting (730; 820) one of the first transmission or the second transmission for transmission based at least in part on a characteristic of at least one of the first transmission or the second transmission identified using the set of indicators; and transmitting (740; 830) the selected one of the first transmission or the second transmission based at least in part on selecting the one of the first transmission or the second transmission, wherein the first transmission is a physical uplink shared channel, PUSCH, transmission scheduled by a preconfigured uplink grant from a base station and the second transmission is a PUSCH transmission scheduled by a dynamic uplink grant from the base station; characterized in that the characteristic comprises a first radio network temporary identifier, RNTI, used to indicate a first modulation and coding scheme, MCS, to be used for the first transmission, wherein the preconfigured uplink grant is scrambled using the first RNTI; and wherein selecting (730; 820) one of the first transmission or the second transmission based at least in part on the characteristic comprises: selecting the first transmission when the first RNTI indicates that the first transmission is to use a high-reliability MCS satisfying a reliability requirement for a ultra reliable low latency communications, URLLC, service; and selecting the second transmission when the first RNTI indicates that the first transmission is not to use the high-reliability MCS. selecting the first transmission when the first RNTI indicates that the first transmission is to use a high-reliability MCS satisfying a reliability requirement for a ultra reliable low latency communications, URLLC, service; and selecting the second transmission when the first RNTI indicates that the first transmission is not to use the high-reliability MCS.
