An apparatus to be used in a user equipment, UE, in a mobile communication network to communicate with an evolved Node B, eNB, or a next generation Node B, gNB, comprising: a memory to store information about a threshold condition; and processing circuitry (102, 104, 106, 108) to: identify an uplink grant for a first physical resource of a first configuration associated with a first service having a first priority, the first physical resource of the first configuration comprising a first transmission time interval, TTI; identify data associated with a second service having a second priority, wherein the data is related to a second physical resource of a second configuration, the second physical resource of the second configuration comprising a second TTI, and the first priority is lower than the second priority; and determine whether the threshold condition is met, wherein the threshold condition is associated with the first configuration, the second configuration, the first priority, or the second priority, and wherein the threshold condition is that a length of the second TTI is larger than or equal to half a length of the first TTI; and cause, based on the threshold condition, the data associated with the second service to be transmitted by the first physical resource of the first configuration associated with the first service when the length of the second TTI is larger than or equal to half the length of the first TTI. a memory to store information about a threshold condition; and processing circuitry (102, 104, 106, 108) to: identify an uplink grant for a first physical resource of a first configuration associated with a first service having a first priority, the first physical resource of the first configuration comprising a first transmission time interval, TTI; identify data associated with a second service having a second priority, wherein the data is related to a second physical resource of a second configuration, the second physical resource of the second configuration comprising a second TTI, and the first priority is lower than the second priority; and determine whether the threshold condition is met, wherein the threshold condition is associated with the first configuration, the second configuration, the first priority, or the second priority, and wherein the threshold condition is that a length of the second TTI is larger than or equal to half a length of the first TTI; and cause, based on the threshold condition, the data associated with the second service to be transmitted by the first physical resource of the first configuration associated with the first service when the length of the second TTI is larger than or equal to half the length of the first TTI. identify an uplink grant for a first physical resource of a first configuration associated with a first service having a first priority, the first physical resource of the first configuration comprising a first transmission time interval, TTI; identify data associated with a second service having a second priority, wherein the data is related to a second physical resource of a second configuration, the second physical resource of the second configuration comprising a second TTI, and the first priority is lower than the second priority; and determine whether the threshold condition is met, wherein the threshold condition is associated with the first configuration, the second configuration, the first priority, or the second priority, and wherein the threshold condition is that a length of the second TTI is larger than or equal to half a length of the first TTI; and cause, based on the threshold condition, the data associated with the second service to be transmitted by the first physical resource of the first configuration associated with the first service when the length of the second TTI is larger than or equal to half the length of the first TTI.
