There is provided a method performed by a wireless device for supporting transmission to a network node in a wireless communication network according to an embodiment. The method is adapted for a wireless network based on LTE, wherein the wireless device is allowed to transmit on a set of Resource Elements, REs, allocated for transmission to the network node. The method comprises the step (S1) of determining at least one transport format control parameter for at least a first part of the set of REs allocated for transmission. The method further comprises the step (S2) of transmitting, to the network node, an indication representing the at least one determined transport format control parameter on at least a second part of the set of REs allocated for transmission to notify the network node of the determined transport format control parameter(s).
