Performing inter-frequency measurements in a mobile network
View Patent ↗Methods, apparatus and articles of manufacture for performing inter-frequency measurements in a mobile network are disclosed. Example methods disclosed herein include a mobile station receiving, from a network, one or more lists specifying a set of frequencies for which measurements are to be performed. Such example methods also include the mobile station varying a rate at which the measurements are to be performed for a first frequency of the set of frequencies based on a number of frequencies for which the measurements are to be performed.
1. A method in a mobile station, the method comprising:
receiving, by the mobile station, a frequency list specifying a set of frequencies for which measurements are to be performed; and
receiving, by the mobile station, information that indicates a subset of frequencies from the set of frequencies for reduced measurement performance;
wherein measurement performance includes cell reselection timing performance,
wherein the set of frequencies comprises a first subset of frequencies, and the information received by the mobile station indicates a second subset of frequencies having reduced cell reselection performance compared with the first subset of frequencies in the frequency list, and
wherein frequencies with normal or reduced measurement performance requirements are distinguished within the frequency list.
2. The method of claim 1 , wherein the first subset of frequencies are listed first in the frequency list, and the second subset of frequencies are listed after the first subset of frequencies.
3. The method of claim 1 , wherein the information received by the mobile station indicates which frequencies have reduced cell reselection performance scaled proportionally to a number of frequencies on which the mobile station is to perform measurements.
4. The method of claim 1 , wherein the mobile station is camped on an UTRAN Cell or an E-UTRAN Cell.
5. The method of claim 4 , wherein the mobile station monitors UTRAN Cells or E-UTRAN Cells.
6. The method of claim 1 , further comprising performing reference signal received power (RSRP) measurements for the set of frequencies including the subset of frequencies.
7. A non-transitory computer readable medium storing instructions to cause a processor to perform operations comprising:
receiving, by a mobile station, a frequency list specifying a set of frequencies for which measurements are to be performed; and
receiving, by the mobile station, information that indicates a subset of frequencies from the set of frequencies for reduced measurement performance;
wherein measurement performance includes cell reselection timing performance,
wherein the set of frequencies comprises a first subset of frequencies, and the information received by the mobile station indicates a second subset of frequencies having reduced cell reselection performance compared with the first subset of frequencies in the frequency list, and
wherein frequencies with normal or reduced measurement performance requirements are distinguished within the frequency list.
8. The computer readable medium of claim 7 , wherein the first subset of frequencies are listed first in the frequency list, and the second subset of frequencies are listed after the first subset of frequencies.
9. The computer readable medium of claim 7 , wherein the information received by the mobile station indicates which frequencies have reduced cell reselection performance scaled proportionally to a number of frequencies on which a mobile station is to perform measurements.
10. The computer readable medium of claim 7 , wherein the processor is camped on an UTRAN Cell or an E-UTRAN Cell.
11. The computer readable medium of claim 10 , wherein the processor monitors UTRAN Cells or E-UTRAN Cells.
12. The computer readable medium of claim 7 , the instructions further comprising performing reference signal received power (RSRP) measurements for the set of frequencies including the subset of frequencies.
13. A user equipment (UE), comprising:
one or more processors configured to:
receive, by the UE, a frequency list specifying a set of frequencies for which measurements are to be performed; and
receive, by the UE, information that indicates a subset of frequencies from the set of frequencies for reduced measurement performance;
wherein measurement performance includes cell reselection timing performance,
wherein the set of frequencies comprises a first subset of frequencies, and the information received by the mobile station indicates a second subset of frequencies having reduced cell reselection performance compared with the first subset of frequencies in the frequency list, and
wherein frequencies with normal or reduced measurement performance requirements are distinguished within the frequency list.
14. The UE of claim 13 , wherein the first subset of frequencies are listed first in the frequency list, and the second subset of frequencies are listed after the first subset of frequencies.
15. The UE of claim 13 , wherein the information received by the UE indicates which frequencies have reduced cell reselection performance scaled proportionally to a number of frequencies on which a mobile station is to perform measurements.
16. The UE of claim 13 , wherein the UE is camped on an UTRAN Cell or an E-UTRAN Cell.
17. The UE of claim 16 , wherein the UE monitors UTRAN Cells or E-UTRAN Cells.
18. The UE of claim 13 , the one or more processors configured to perform reference signal received power (RSRP) measurements for the set of frequencies including the subset of frequencies.
