Abstract
There is provided a method for a first network element of a wireless communication network, the method comprising: obtaining blanked subcarrier index data indicating one or more blanked subcarriers in a time-frequency resource grid; initiating reception of a transmission from a second network element of the wireless communication network on said time-frequency resource grid; causing performing an interference measurement on said one or more blanked subcarriers to obtain interference measurement data on said one or more blanked subcarriers; and outputting the interference measurement data for detecting a presence of radio jamming.
Claims12
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to perform:
- receiving pseudorandom algorithm information from a control network element of a wireless communication network;
- determining blanked subcarrier index data based on the received pseudorandom algorithm information, the blanked subcarrier index data indicating one or more blanked subcarriers in a time-frequency resource grid, wherein the blanked subcarrier index data is generated utilizing a pseudorandom algorithm information determined by the control network element of the wireless communication network;
- initiating reception of a transmission from a network element of the wireless communication network on said time-frequency resource grid;
- causing performing an interference measurement on said one or more blanked subcarrier to obtain interference measurement data on said one or more blanked subcarriers;
- outputting the interference measurement data for detecting a presence of radio jamming;
- and
- transmitting the interference measurement data for detecting the presence of radio jamming to the control network element.
