Abstract
A method of operating a mobile device in a wireless communication network, the method comprising measuring interference at the mobile device, determining whether to report the measured interference to the network, and, if it is determine to report the measured interference to the network, transmitting an interference measurement report to the network including an indication of the time interference was measured. Also described is a method of operating a network node in a wireless communication network.
Claims12
A method performed by a terminal in a wireless communication system, the method comprising:
- receiving, from a base station, a first message including first information configuring a timing for a measurement of a received signal strength indicator (RSSI) and second information configuring a report of the RSSI, the second information further including information on a threshold for the measurement of the RSSI;
- performing the measurement of the RSSI during the timing determined by the first information;
- identifying a percentage of samples for which a measured RSSI is above the threshold based on the information on the threshold included in the second information;
- transmitting, to the base station, a result of the measurement of the RSSI based on the second information, the result including the percentage of samples, a specific time of which the measured RSSI is above the threshold, and an indicator indicating an interference level which is a quantization of the measured RSSI;
- receiving, from the base station, a second message requesting additional measurement information, wherein the second message is generated based on a determination that a hidden node exists within a communication range of the terminal and outside a communication range of the base station, by comparing the result of the measurement with an interference measured by the base station;
- and
- transmitting, to the base station, a report of an additional interference measurement result per each time slot for which the measured RSSI is above the threshold, the additional interference measurement result including an actual measured interference value for a corresponding time slot.
