Abstract

A measurement relaxation method, a user equipment, a computer program and a computer readable medium are provided. The method includes: receiving, by User Equipment (UE), first information indicating that measurement relaxation on a high priority frequency is allowed; and performing, by the UE, measurement relaxation on the high priority frequency according to the first information.

First claim

The invention claimed is:

1. A method for measurement relaxation, comprising:
receiving, by User Equipment (UE), first information indicating measurement relaxation on a high priority frequency;
performing, by the UE, measurement relaxation on the high priority frequency according to the first information when:
the first information indicates that the measurement relaxation on the high priority frequency is allowed; and
a low-mobility criterion is fulfilled for a period.

2. The method of claim 1 , comprising:
when a relaxed measurement criterion is fulfilled, performing measurement relaxation on the high priority frequency after receiving the first information.

3. The method of claim 2 , wherein the relaxed measurement criterion is fulfilled comprising:
the relaxed measurement criterion is fulfilled for a period.

4. The method of claim 2 , wherein the relaxed measurement criterion is fulfilled for a period comprising:
a measurement of the serving cell of the UE satisfies the relaxed measurement criterion for a period.

5. The method of claim 4 , wherein
the measurement of the serving cell includes least one of the followings: Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR).

6. The method of claim 2 , wherein the relaxed measurement criterion is a low-mobility criterion.

7. The method of claim 1 , where performing measurement relaxation on the high priority frequency refers to one of the followings:
the UE not performing measurement on the high priority frequency;
the UE performing measurement on the high priority frequency using a longer measurement period or sampling interval than that of a normal measurement on the high priority frequency.

8. The method of claim 1 , wherein the high priority frequency refers to a frequency whose cell reselection priority is higher than the cell reselection priority of the frequency of the serving cell.

9. The method of claim 1 , wherein the high priority frequency refers to a frequency of an inter-frequency reselection or a frequency of an inter Radio Access Technology (inter-RAT) frequency reselection.

10. The method of claim 1 , wherein the first information is configured by a network side device.

11. The method of claim 1 , wherein the first information is in first system information broadcasted by a network side device.

12. The method of claim 11 , wherein
the first system information is at least one of the followings: a master information block (MIB), a system information block (SIB), minimum system information (MSI), remaining minimum system information (RMSI).

13. The method of claim 11 , wherein the network side device is a based station.

14. The method of claim 13 , wherein the based station is the base station of the serving cell.

15. The method of claim 13 , wherein the based station is an eNodeB in a Long Term Evolution (LTE) system and/or a gNodeB in New Radio (NR) in a 5G system.

16. A user equipment (UE), comprising: a processor and a storage medium, wherein the storage medium is configured to store a computer program, and the processor is configured to invoke and run the computer program stored in the storage medium to
receive first information indicating measurement relaxation on a high priority frequency; and
perform measurement relaxation on the high priority frequency according to the first information when:
the first information indicates that the measurement relaxation on the high priority frequency is allowed; and
a low-mobility criterion is fulfilled for a period.

17. A method for measurement relaxation, comprising:
sending, by a network side device, first information to a user equipment;
wherein the first information indicates measurement relaxation, performing by the user equipment, on a high priority frequency;
wherein the first information is for the user equipment to perform the measurement relaxation on the high priority frequency when:
the first information indicates that the measurement relaxation on the high priority frequency is allowed; and
a low-mobility criterion is fulfilled for a period.

18. The method of claim 17 , wherein the high priority frequency refers to a frequency whose cell reselection priority is higher than the cell reselection priority of the frequency of the serving cell.

19. A network side device, comprising: a processor and a memory, wherein the memory is configured to store a computer program, and the processor is configured to invoke and run the computer program stored in the memory to
send first information to a user equipment;
wherein the first information indicates measurement relaxation, performing by the user equipment, on a high priority frequency;
wherein the first information is for the user equipment to perform the measurement relaxation on the high priority frequency when:
the first information indicates that the measurement relaxation on the high priority frequency is allowed; and
a low-mobility criterion is fulfilled for a period.

20. A non-transitory computer readable medium, comprising instructions for causing user equipment to perform the method of claim 1 .
