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.
Claims18
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.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer 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:
- determining a blanking pattern information for blanking one or more subcarriers of a time-frequency resource grid;
- configuring a plurality of network nodes of the wireless communication network to utilize said blanking pattern information to blank the one or more subcarriers;
- receiving interference information from a network node of the plurality of network nodes, the interference information obtained based on one or more measurements performed on the one or more blanked subcarriers;
- determining a presence of radio jamming based on the received interference information;
- and
- in case the presence of radio jamming is determined, initiating one or more actions to mitigate the determined radio jamming.
