Methods for Handling Logging of Different Types of Measurements in SON Reports

A method, in a wireless device, for collecting measurement results, the method comprising:

• selecting, for inclusion in a report stored by the wireless device, first radio quality measurement results based on a first type of at least two types of reference signals used by the wireless device for measuring radio quality, wherein said selecting comprises selecting radio quality measurement results reflecting the best radio quality, among available radio quality measurement results based on the first type of reference signal, for neighbor cells;
• including the selected first radio quality measurement results in the report;
• and
• including in the report, along with the selected first radio quality measurement results, one or more available radio quality measurement results corresponding to the cell identifiers associated to the selected radio quality measurement results and based on a second type of the at least two types of reference signals,
• wherein the selected first radio quality measurement results number less than a predetermined maximum number of radio quality measurement results, and wherein the method comprises further including, in the report, one or more additional radio quality measurement results based on the second type of reference signal, up to a number of additional radio quality measurement results such that the total number of the selected first radio quality measurement results and the number of additional radio quality measurement results equals the predetermined maximum number, wherein the additional radio quality measurement results comprise radio quality measurements reflecting the best radio quality among available radio measurements for neighbor cells based on the second type of reference signal and for cells not corresponding to the cell identifiers associated with the selected first radio quality measurement results.

A wireless device, comprising

• a transmitter and receiver configured for communication with a wireless network;
• and
• processing circuitry operatively coupled to the transmitter and receiver and configured to:
• select, for inclusion in a report stored by the wireless device, first radio quality measurement results based on a first type of at least two types of reference signals used by the wireless device for measuring radio quality, wherein said selecting comprises selecting radio quality measurement results reflecting the best radio quality, among available radio quality measurement results based on the first type of reference signal, for neighbor cells;
• include the selected first radio quality measurement results in the report;
• and
• include in the report, along with the selected first radio quality measurement results, one or more available radio quality measurement results corresponding to the cell identifiers associated to the selected radio quality measurement results and based on a second type of the at least two types of reference signals,
• wherein the selected first radio quality measurement results number less than a predetermined maximum number of radio quality measurement results, and wherein the processing circuitry is configured to include, in the report, one or more additional radio quality measurement results based on the second type of reference signal, up to a number of additional radio quality measurement results such that the total number of the selected first radio quality measurement results and the number of additional radio quality measurement results equals the predetermined maximum number, wherein the additional radio quality measurement results comprise radio quality measurements reflecting the best radio quality among available radio measurements for neighbor cells based on the second type of reference signal and for cells not corresponding to the cell identifiers associated with the selected first radio quality measurement results.

A computer-readable medium comprising, stored thereupon, a computer program product comprising instructions, for execution by a processing circuit of a wireless device, the instructions being configured to cause the wireless device to:

• select, for inclusion in a report stored by the wireless device, first radio quality measurement results based on a first type of at least two types of reference signals used by the wireless device for measuring radio quality, wherein said selecting comprises selecting radio quality measurement results reflecting the best radio quality, among available radio quality measurement results based on the first type of reference signal, for neighbor cells;
• include the selected first radio quality measurement results in the report;
• and
• include in the report, along with the selected first radio quality measurement results, one or more available radio quality measurement results corresponding to the cell identifiers associated to the selected radio quality measurement results and based on a second type of the at least two types of reference signals,
• wherein the selected first radio quality measurement results number less than a predetermined maximum number of radio quality measurement results, and wherein the instructions being further configured to cause the wireless device to include, in the report, one or more additional radio quality measurement results based on the second type of reference signal, up to a number of additional radio quality measurement results such that the total number of the selected first radio quality measurement results and the number of additional radio quality measurement results equals the predetermined maximum number, wherein the additional radio quality measurement results comprise radio quality measurements reflecting the best radio quality among available radio measurements for neighbor cells based on the second type of reference signal and for cells not corresponding to the cell identifiers associated with the selected first radio quality measurement results.
