Obtaining additional supported bands of neighbor cells via automatic neighbor relation (ANR)
Systems, methods, apparatuses, and computer program products for obtaining additional supported bands of neighbor cell(s) are provided. One method includes reading, by a user equipment, a frequency band list broadcast by at least one neighbor cell, and reporting the frequency band list to a cell serving the user equipment.
1. A method, comprising:
reading, by a user equipment, a frequency band list broadcast by a neighbor cell, wherein the frequency band list comprises additional frequency bands supported by said neighbor cell;
reporting, to a cell serving the user equipment, the frequency band list comprising the frequency bands supported by said neighbor cell; and
adding an information element comprising the frequency band list to a measurement report, and wherein the reporting comprises sending the measurement report comprising the information element to the serving cell, wherein the adding further comprises adding the information element to the measurement report when the measurement report is for a reportCGI measurement, when the user equipment is capable of reporting the frequency band list to the serving cell in the measurement report, and when the neighbor cell supports additional frequency bands.
2. The method according to claim 1 , wherein the adding further comprises adding a new parameter in lateNonCriticalExtension of the measurement report.
3. The method according to claim 1 , wherein the measurement report comprises MeasResultEUTRA or MeasResultUTRA.
4. 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 at least to
read a frequency band list broadcast by a neighbor cell, wherein the frequency band list comprises additional frequency bands supported by said neighbor cell;
report, to a cell serving the apparatus, the frequency band list comprising the frequency bands supported by said neighbor cell; and
add an information element comprising the frequency band list to a measurement report, and wherein the reporting comprises sending the measurement report comprising the information element to the serving cell, wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the apparatus at least to add the information element to the measurement report when the measurement report is for a reportCGI measurement, when the apparatus is capable of reporting the frequency band list to the serving cell in the measurement report, and when the neighbor cell supports additional frequency bands.
5. The apparatus according to claim 4 , wherein the apparatus is a user equipment.
6. The apparatus according to claim 4 , wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the apparatus at least to add a new parameter in lateNonCriticalExtension of the measurement report.
7. The apparatus according to claim 4 , wherein the measurement report comprises MeasResultEUTRA or MeasResultUTRA.
8. A computer program, embodied on a non-transitory computer readable medium, the computer program configured to control a processor of a user equipment to perform a process, comprising:
reading a frequency band list broadcast by a neighbor cell, wherein the frequency band list comprises additional frequency bands supported by said neighbor cell;
reporting, to a cell serving the user equipment, the frequency band list comprising the frequency bands supported by said neighbor cell; and
adding an information element comprising the frequency band list to a measurement report, and wherein the reporting comprises sending the measurement report comprising the information element to the serving cell, wherein the adding further comprises adding the information element to the measurement report when the measurement report is for a reportCGI measurement, when the computer program is capable of reporting the frequency band list to the serving cell in the measurement report, and when the neighbor cell supports additional frequency bands.
9. The computer program according to claim 8 , wherein the adding further comprises adding a new parameter in lateNonCriticalExtension of the measurement report.
10. The computer program according to claim 8 , wherein the measurement report comprises MeasResultEUTRA or MeasResultUTRA.
