A method in a first node for determining radio characteristics of a radio link between a first repeater and at least one second repeater, wherein the first repeater is managed by the first node, wherein the first and second repeaters (103, 104) are on-frequency repeaters, wherein the first node, the first repeater (103, 203) and said at least one second repeater (104, 204) are comprised in a Long Term Evolution network, the method comprising: sending a first message to the first repeater (103, 203), wherein the first message comprises instructions to the first repeater (103, 203) to send a radio signal being measureable by the second repeater (104, 204), wherein the radio signal is any data signal or a reference signal, sending a second message to said at least one second repeater (104, 204), wherein the second message comprises instructions to said at least one second repeater (104, 204) to measure on the radio signal to be received from the first repeater (103, 203), receiving measurement data from said at least one second repeater (104, 204), wherein the measurement data is measured by said at least one second repeater (104, 204) and is measured on the radio signal received from the first repeater (103, 203), determining radio characteristics of the radio link between the first repeater (103, 203) and said at least one second repeater (104, 204) based on the measurement data, wherein the instructions to the first repeater further comprise instructions to assign a measurement resource to the first repeater, and the method further comprises: sending a fourth message to a communication device comprised in the Long Term Evolution network, wherein the fourth message comprises instructions to the communication device to assign a data transmission resource to the communication device, wherein the measurement and data transmission resources are orthogonal or near orthogonal resources non-overlapping in frequency. sending a first message to the first repeater (103, 203), wherein the first message comprises instructions to the first repeater (103, 203) to send a radio signal being measureable by the second repeater (104, 204), wherein the radio signal is any data signal or a reference signal, sending a second message to said at least one second repeater (104, 204), wherein the second message comprises instructions to said at least one second repeater (104, 204) to measure on the radio signal to be received from the first repeater (103, 203), receiving measurement data from said at least one second repeater (104, 204), wherein the measurement data is measured by said at least one second repeater (104, 204) and is measured on the radio signal received from the first repeater (103, 203), determining radio characteristics of the radio link between the first repeater (103, 203) and said at least one second repeater (104, 204) based on the measurement data, wherein the instructions to the first repeater further comprise instructions to assign a measurement resource to the first repeater, and the method further comprises: sending a fourth message to a communication device comprised in the Long Term Evolution network, wherein the fourth message comprises instructions to the communication device to assign a data transmission resource to the communication device, wherein the measurement and data transmission resources are orthogonal or near orthogonal resources non-overlapping in frequency. sending a fourth message to a communication device comprised in the Long Term Evolution network, wherein the fourth message comprises instructions to the communication device to assign a data transmission resource to the communication device, wherein the measurement and data transmission resources are orthogonal or near orthogonal resources non-overlapping in frequency.
