Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish a radio resource control (RRC) connection with a base station. The UE may receive, from the base station, parameters associated with a set of frequency bands, the parameters indicating a priority of each frequency band of the set of frequency bands. The UE may then measure, based on the priority, one or more frequencies of at least one frequency band of the set of frequency bands. The UE may then transmit, after a time delay and to the base station, a measurement report including measurements of one or more frequency bands of the set of frequency bands.

First claim

What is claimed is:

1. A method for wireless communications at a user equipment (UE), comprising:
establishing a radio resource control connection with a network entity;
receiving, from the network entity, parameters associated with a plurality of frequency bands, the parameters indicating a respective priority of each frequency band of the plurality of frequency bands;
measuring, based at least in part on a priority of at least one frequency band, one or more frequencies of the at least one frequency band of the plurality of frequency bands; and
transmitting, after a time delay and to the network entity, a measurement report comprising measurements of one or more frequency bands of the plurality of frequency bands, wherein the time delay is associated with measurement of at least one other frequency band of the plurality of frequency bands.

2. The method of claim 1 , further comprising:
transmitting, to the network entity, an indication of the priority to measure each frequency band of the plurality of frequency bands; and
receiving a configuration of the plurality of frequency bands based at least in part on the indication.

3. The method of claim 2 , wherein the indication of the priority is based at least in part on a location of the UE.

4. The method of claim 1 , further comprising:
configuring a measurement gap for each frequency band of the plurality of frequency bands based at least in part on the priority.

5. The method of claim 4 , wherein a first measurement gap is associated with a first frequency band of the plurality of frequency bands.

6. The method of claim 1 , wherein the measurements comprise reference signal received power measurements or reference signal received quality measurements, or a combination thereof.

7. The method of claim 1 , further comprising:
transmitting the measurement report of a first measurement of a first frequency band, based at least in part on the first measurement satisfying a measurement threshold.

8. The method of claim 7 , wherein the measurement threshold comprises a network measurement threshold and a UE measurement threshold.

9. The method of claim 1 , wherein the time delay is based at least in part on at least one measurement satisfying a network measurement threshold and failing to satisfy a UE measurement threshold.

10. The method of claim 9 , further comprising:
performing measurements of the at least one frequency band of the plurality of frequency bands based at least in part on the time delay of transmitting the measurement report.

11. The method of claim 1 , wherein the parameters comprise a frequency range associated with each frequency band of the plurality of frequency bands, and wherein measuring the one or more frequencies comprises:
measuring the one or more frequencies of the at least one frequency band based at least in part on an order of the frequency range of each frequency band of the plurality of frequency bands.

12. The method of claim 11 , wherein the parameters comprise a database presence associated with each frequency band of the plurality of frequency bands, and wherein measuring the one or more frequencies comprises:
measuring the one or more frequencies of the at least one frequency band based at least in part on an order of the database presence of each frequency band of the plurality of frequency bands.

13. The method of claim 12 , wherein the parameters comprise a duplexing configuration of each frequency band of the plurality of frequency bands, and wherein measuring the one or more frequencies comprises:
measuring the one or more frequencies of the at least one frequency band based at least in part on the duplexing configuration of each frequency band of the plurality of frequency bands.

14. The method of claim 13 , wherein the parameters comprise a time to trigger configuration of each frequency band of the plurality of frequency bands, and wherein measuring the one or more frequencies comprises:
measuring the one or more frequencies of the at least one frequency band based at least in part on the time to trigger configuration of each frequency band of the plurality of frequency bands.

15. The method of claim 14 , wherein the parameters comprise a system bandwidth configuration of each frequency band of the plurality of frequency bands, and wherein measuring the one or more frequencies comprises:
measuring the one or more frequencies of the at least one frequency band based at least in part on the system bandwidth configuration of each frequency band of the plurality of frequency bands.

16. A method for wireless communications at a network entity, comprising:
establishing a radio resource control connection with a user equipment (UE);
transmitting, to the UE, parameters associated with a plurality of frequency bands, the parameters indicating a respective priority of each frequency band of the plurality of frequency bands; and
receiving, after a time delay and from the UE, a measurement report comprising measurements of one or more frequency bands of the plurality of frequency bands, the measurements performed according to an indicated priority of the one or more frequency bands, wherein the time delay is associated with measurement of at least one other frequency band of the plurality of frequency bands.

17. The method of claim 16 , further comprising:
receiving, from the UE, an indication of the respective priority to measure each frequency band of the plurality of frequency bands; and
transmitting a configuration of the plurality of frequency bands based at least in part on the indication.

18. The method of claim 17 , wherein the indication is based at least in part on a location of the UE.

19. The method of claim 16 , wherein the measurements comprise reference signal received power measurements or reference signal received quality measurements, or a combination thereof.

20. The method of claim 16 , further comprising:
receiving the measurement report of a first measurement of a first frequency band, based at least in part on the first measurement satisfying a measurement threshold.

21. The method of claim 20 , wherein the measurement threshold comprises a network measurement threshold and a UE measurement threshold.

22. The method of claim 16 , wherein the time delay is based at least in part on at least one measurement satisfying a network measurement threshold and failing to satisfy a UE measurement threshold.
