Abstract

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media for a UE to prioritize gapless measurements. The UE receives an enquiry for capabilities of the UE with respect to a set of bands. The UE determines a portion of the set of bands that can be measured without a measurement gap. The UE indicates a status of the UE to measure all of the bands in the set of bands without a measurement gap when the portion of the set of bands is greater than a first threshold or connected mode discontinuous reception (CDRX) is configured. The UE receives a configuration for inter-band measurements without a measurement gap. The UE transmits a measurement report for inter-band measurements without a measurement for one or more bands that the UE cannot measure without a measurement gap.

Claims (52)

1 . A method of wireless communications at a user equipment (UE), the method comprising:

receiving an enquiry for capabilities of the UE with respect to a set of bands;

determining a portion of the set of bands that can be measured without a measurement gap;

indicating a status of the UE to measure all of the bands in the set of bands without a measurement gap in response to the portion of the set of bands being greater than a first threshold or connected mode discontinuous reception (CDRX) being configured;

receiving a configuration for inter-band measurements without a measurement gap; and

transmitting a measurement report for inter-band measurements without a measurement for one or more bands in the configuration for inter-band measurements that the UE cannot measure without a measurement gap.

2 . The method of claim 1 , wherein the UE cannot measure at least one band in the set of bands without a measurement gap.

3 . The method of claim 1 , further comprising performing a gapless measurement on the portion of the set of bands.

4 . The method of claim 1 , wherein determining the portion of the set of bands that can be measured without a measurement gap comprises determining that each band in the set of bands that can be measured without a measurement gap is in an advertised band combination with a band of a primary cell.

5 . The method of claim 1 , wherein determining the portion of the set of bands that can be measured without a measurement gap comprises determining that one or more bands that cannot be measured without a measurement gap is included in the portion of the set of bands that can be measured without a measurement gap when a record of previously acquired cells indicates no cells in the one or more bands that cannot be measured without a measurement gap.

6 . The method of claim 5 , wherein the portion of the set of bands that can be measured without a measurement gap is less than the first threshold but greater than a second threshold, and the portion of the set of bands that can be measured without a measurement gap plus the one or more bands that cannot be measured without a measurement gap without a record of previously acquired cells is greater than the first threshold.

7 . The method of claim 1 , further comprising performing a measurement of one or more bands which the UE cannot measure without a measurement gap during an off portion of a CDRX cycle.

8 . The method of claim 1 , further comprising transmitting UE assistance information updating the capability of the UE to measure all of the bands in the set of bands without a measurement gap.

9 . The method of claim 1 , wherein indicating the status of the UE is based on a power saving mode or a low mobility mode.

10 . An apparatus for wireless communications at a user equipment (UE), comprising:

one or more memories, individually or in combination, storing computer-executable instructions; and

one or more processors, individually or in combination, configured to execute the instructions to:

receive an enquiry for capabilities of the UE with respect to a set of bands;

determine a portion of the set of bands that can be measured without a measurement gap;

indicate a status of the UE to measure all of the bands in the set of bands without a measurement gap in response to the portion of the set of bands being greater than a first threshold or connected mode discontinuous reception (CDRX) being configured;

receive a configuration for inter-band measurements without a measurement gap; and

transmit a measurement report for inter-band measurements without a measurement for one or more bands in the configuration for inter-band measurements that the UE cannot measure without a measurement gap.

11 . The apparatus of claim 10 , wherein the UE cannot measure at least one band in the set of bands without a measurement gap.

12 . The apparatus of claim 10 , wherein the one or more processors, individually or in combination, are configured to perform a gapless measurement on the portion of the set of bands.

13 . The apparatus of claim 10 , wherein to determine the portion of the set of bands that can be measured without a measurement gap, the one or more processors, individually or in combination, are configured to determine that each band in the set of bands that can be measured without a measurement gap is in an advertised band combination with a band of a primary cell.

14 . The apparatus of claim 10 , wherein to determine the portion of the set of bands that can be measured without a measurement gap, the one or more processors, individually or in combination, are configured to determine that one or more bands that cannot be measured without a measurement gap is included in the portion of the set of bands that can be measured without a measurement gap when a record of previously acquired cells indicates no cells in the one or more bands that cannot be measured without a measurement gap.

15 . The apparatus of claim 14 , wherein the portion of the set of bands that can be measured without a measurement gap is less than the first threshold but greater than a second threshold, and the portion of the set of bands that can be measured without a measurement gap plus the one or more bands that cannot be measured without a measurement gap without a record of previously acquired cells is greater than the first threshold.

16 . The apparatus of claim 10 , wherein the one or more processors, individually or in combination, are configured to perform a measurement of one or more bands which the UE cannot measure without a measurement gap during an off portion of a CDRX cycle.

17 . The apparatus of claim 10 , wherein the one or more processors, individually or in combination, are configured to transmit UE assistance information updating the status of the UE to measure all of the bands in the set of bands without a measurement gap.

18 . The apparatus of claim 10 , wherein the indication of the status of the UE is based on a power saving mode or a low mobility mode.

19 . An apparatus for wireless communications at a user equipment (UE), the apparatus comprising:

means for receiving an enquiry for capabilities of the UE with respect to a set of bands;

means for determining a portion of the set of bands that can be measured without a measurement gap;

means for indicating a status of the UE to measure all of the bands in the set of bands without a measurement gap in response to the portion of the set of bands being greater than a first threshold or connected mode discontinuous reception (CDRX) being configured;
