A method of operation for a network node of a communication network, the method comprising: determining (400A-F), by the network node, that a target transmission power for an upcoming transmission by the network node is no longer optimal, wherein the upcoming transmission has at least a given modulation and coding scheme, MCS, or a given set of resources; autonomously modifying (402A-F), by the network node in response to the determining, at least one parameter of the upcoming transmission, from the at least one of the given MCS or the given set resources for the upcoming transmission; transmitting, by the network node, a first channel, based at least in part on the one or more modified parameters, to a second network node of the communication network in the subsequent transmission; further comprising at least one of: refraining from providing any indication, by the network node to the second network node, of the autonomous modification of the at least one parameter, or providing (404B, 404D, 404F) an indication, by the network node to the second network node, of the autonomous modification by selecting a characteristic of a demodulation reference signal, DMRS, that is predetermined to correspond to the autonomous modification, or providing an indication, by the network node to the second network node, of the autonomous modification in a control part of the upcoming transmission; and further comprising one of: transmitting, by the network node to the second network node, a request for additional resources and receiving a grant for additional resources, or receiving, from the second network node, a grant for additional resources based on the second network node determining that the network node made an autonomous modification. determining (400A-F), by the network node, that a target transmission power for an upcoming transmission by the network node is no longer optimal, wherein the upcoming transmission has at least a given modulation and coding scheme, MCS, or a given set of resources; autonomously modifying (402A-F), by the network node in response to the determining, at least one parameter of the upcoming transmission, from the at least one of the given MCS or the given set resources for the upcoming transmission; transmitting, by the network node, a first channel, based at least in part on the one or more modified parameters, to a second network node of the communication network in the subsequent transmission; further comprising at least one of: refraining from providing any indication, by the network node to the second network node, of the autonomous modification of the at least one parameter, or providing (404B, 404D, 404F) an indication, by the network node to the second network node, of the autonomous modification by selecting a characteristic of a demodulation reference signal, DMRS, that is predetermined to correspond to the autonomous modification, or providing an indication, by the network node to the second network node, of the autonomous modification in a control part of the upcoming transmission; and refraining from providing any indication, by the network node to the second network node, of the autonomous modification of the at least one parameter, or providing (404B, 404D, 404F) an indication, by the network node to the second network node, of the autonomous modification by selecting a characteristic of a demodulation reference signal, DMRS, that is predetermined to correspond to the autonomous modification, or providing an indication, by the network node to the second network node, of the autonomous modification in a control part of the upcoming transmission; and further comprising one of: transmitting, by the network node to the second network node, a request for additional resources and receiving a grant for additional resources, or receiving, from the second network node, a grant for additional resources based on the second network node determining that the network node made an autonomous modification. transmitting, by the network node to the second network node, a request for additional resources and receiving a grant for additional resources, or receiving, from the second network node, a grant for additional resources based on the second network node determining that the network node made an autonomous modification.
