Methods and modules for handling channels in a radio spectrum

A method, performed by an Operating Channel Assessment “OCA” module of a radio network node (BS), for handling a request for at least one channel, wherein the method comprises:

• receiving, from an Radio Resource Management “RRM” module of the radio network node (BS), the request for the at least one channel;
• sending the request and a set of local parameters, wherein the set of local parameters relates to one or more of:
• throughput,
• bandwidth,
• interference,
• frequency, and
• location;
• receiving, from the core network node, one or more channels in a first level assessment;
• assessing, in a second level assessment, said one or more channels in the first level assessment, to obtain at least one second level channel;
• sending said at least one second level channel to the RRM module;
• and
• receiving, from the RRM module, information about a selected one or more channels, wherein a model used for the second level assessment is updated based on the information and wherein the assessing of said one or more channels in the first level assessment to obtain the second level channels is performed by considering a previous second level channel assessment, thereby learning from the previous second level channel assessment.

A method, performed by an Operating Channel Assessment “OCA” module of a core network node, for providing at least one channel operable by a radio network node (BS), wherein the method comprises:

• receiving, from an OCA module of the radio network node (BS), a request for the at least one channel, and a set of local parameters, wherein the set of local parameters relates to one or more of:
• throughput,
• bandwidth,
• interference,
• frequency, and
• location;
• assessing channels, provided by a Global Location database, to select one or more channels in a first level assessment, wherein the assessment is based on the set of local parameters and a set of global parameters, wherein the set of global parameters relates to one or more of:
• frequency,
• location,
• spectrum sharing, and
• spectrum availability;
• and
• sending the first level channels to the OCA module of the radio network node (BS)
• receiving, from the OCA module of the radio network node (BS), a selected one or more channels;
• and
• updating a model used for the first level assessment based on the selected one or more channels;
• and wherein the assessing of the channels to select one or more channels in the first level assessment is performed by considering a previous first level channel assessment, thereby learning from the previous first level channel assessment.

An Operating Channel Assessment “OCA” module of a radio network node (BS), for handling a request for at least one channel, wherein the OCA module comprises a processing circuit and a memory, wherein the memory comprises computer readable code units executable by the processing circuit, whereby the OCA module of the radio network node (BS) is operative to:

• receiving, from an Radio Resource Management “RRM” module of the radio network node (BS), the request for the at least one channel;
• sending the request and a set of local parameters, wherein the set of local parameters relates to one or more of:
• throughput,
• bandwidth,
• interference,
• frequency, and
• location;
• receiving, from the core network node, one or more channels in a first level assessment;
• assessing, in a second level assessment, said one or more channels in the first level assessment, to obtain at least one second level channel;
• and
• sending said at least one second level channel to the RRM module;
• and wherein the OCA module is configured for receiving, from the RRM module, information about a selected one or more channels, wherein a model used for the second level assessment is updated based on the information and wherein the OCA module is configured for assessing of said one or more channels in the first level assessment to obtain the second level channels by considering a previous second level channel assessment, thereby learning from the previous second level channel assessment.
