A method performed by a wireless device for receiving system information from a network node in a wireless communications network , the method comprising: selecting, by the wireless device , a frequency carrier; receiving , by the wireless device , first system information comprising a compressed version of a list of one or more Public Land Mobile Networks, PLMNs, supported on the frequency carrier by the network node , wherein the first system information is transmitted by the network node with a first timing interval; determining , by the wireless device , whether the one or more PLMNs indirectly indicated in the first system information are all not supported PLMN(s) by the wireless device ; and receiving , by the wireless device , second system information comprising a list of all PLMNs supported on the frequency carrier by the network node , when at least one of the one or more PLMNs indirectly indicated in the first system information is a supported PLMN by the wireless device , wherein the second system information is transmitted by the network node with a second timing interval that is longer than the first timing interval, wherein the one or more PLMNs indirectly indicated in the first system information are indicated by fewer bits than a number of bits required to encode one or more PLMNs in the list of all PLMNs comprised in the second system information, and wherein the one or more PLMNs indirectly indicated in the first system information are indicated by one of: a checksum of the one or more PLMNs supported on the frequency carrier by the network node ; an aggregated PLMN identifying two or more PLMNs of the one or more PLMNs supported on the frequency carrier by the network node ; and a bloom filter generated using the one or more PLMNs supported on the frequency carrier by the network node . selecting, by the wireless device , a frequency carrier; receiving , by the wireless device , first system information comprising a compressed version of a list of one or more Public Land Mobile Networks, PLMNs, supported on the frequency carrier by the network node , wherein the first system information is transmitted by the network node with a first timing interval; determining , by the wireless device , whether the one or more PLMNs indirectly indicated in the first system information are all not supported PLMN(s) by the wireless device ; and receiving , by the wireless device , second system information comprising a list of all PLMNs supported on the frequency carrier by the network node , when at least one of the one or more PLMNs indirectly indicated in the first system information is a supported PLMN by the wireless device , wherein the second system information is transmitted by the network node with a second timing interval that is longer than the first timing interval, wherein the one or more PLMNs indirectly indicated in the first system information are indicated by fewer bits than a number of bits required to encode one or more PLMNs in the list of all PLMNs comprised in the second system information, and wherein the one or more PLMNs indirectly indicated in the first system information are indicated by one of: a checksum of the one or more PLMNs supported on the frequency carrier by the network node ; an aggregated PLMN identifying two or more PLMNs of the one or more PLMNs supported on the frequency carrier by the network node ; and a bloom filter generated using the one or more PLMNs supported on the frequency carrier by the network node . a checksum of the one or more PLMNs supported on the frequency carrier by the network node ; an aggregated PLMN identifying two or more PLMNs of the one or more PLMNs supported on the frequency carrier by the network node ; and a bloom filter generated using the one or more PLMNs supported on the frequency carrier by the network node . <EOS>
