Measurement method and apparatus for entering a relaxed measurement state of a serving cell
This application relates to a measurement method and an apparatus. If determining that a terminal device meets a first measurement reporting condition, the terminal device sends first information to a network device. After receiving the first information, the network device sends second information to the terminal device, and the terminal device receives the second information from the network device, where the second information indicates to enter a relaxed measurement state of a serving cell. For such a terminal device, frequent measurement of the serving cell is equivalent to an unnecessary measurement process, and causes high power consumption. Therefore, the network device may indicate such a terminal device to enter the relaxed measurement state of the serving cell.
1. A measurement method, applied to a terminal device comprising one or more processors configured to perform the method, wherein the method comprises:
determining that a first measurement reporting condition is met, wherein the first measurement reporting condition comprises that a measurement result of a serving cell meets a first threshold within a first duration;
sending first information to a network device;
receiving second information from the network device, wherein the second information indicates to enter a relaxed measurement state of the serving cell; and
subsequent to entering the relaxed measurement state, determining a measuring periodicity for obtaining measurement results from the serving cell based on the measurement result of the serving cell.
2. The method according to claim 1 , wherein the method further comprises:
determining that a second measurement reporting condition is met;
sending third information to the network device; and
receiving fourth information from the network device, wherein the fourth information indicates to enter a normal measurement state of the serving cell.
3. The method according to claim 2 , wherein the second measurement reporting condition comprises that the measurement result of the serving cell meets a second threshold within a second duration.
4. The method according to claim 1 , wherein the method further comprises:
determining to enter a normal measurement state of the serving cell after a third duration.
5. The method according to claim 4 , wherein the second information further indicates the third duration.
6. A measurement method, applied to a network device comprising one or more processors configured to perform the method, wherein the method comprises:
receiving first information from a terminal device, wherein the first information includes that a first measurement reporting condition is met, wherein the first measurement reporting condition comprises that a measurement result of a serving cell meets a first threshold within a first duration; and
sending second information to the terminal device, wherein the second information indicates to enter a relaxed measurement state of the serving cell, wherein subsequent to entering the relaxed measurement state the terminal device is configured to determine a measuring periodicity for obtaining measurement results from the serving cell based on the measurement result of the serving cell.
7. The method according to claim 6 , wherein the method further comprises:
receiving third information from the terminal device; and
sending fourth information to the terminal device, wherein the fourth information indicates to enter a normal measurement state of the serving cell.
8. The method according to claim 6 , wherein the second information further indicates a third duration for the terminal device to determine to enter a normal measurement state of the serving cell after the third duration.
9. An apparatus, comprising:
one or more processors; and
one or more memories coupled to the one or more processors and storing programming instructions for an execution by the one or more processors to cause the apparatus to perform a method comprising:
determining that a first measurement reporting condition is met, wherein the first measurement reporting condition comprises that a measurement result of a serving cell meets a first threshold within a first duration;
sending first information to a network device;
receiving second information from the network device, wherein the second information indicates to enter a relaxed measurement state of a serving cell; and
subsequent to entering the relaxed measurement state, determining a measuring periodicity for obtaining measurement results from the serving cell based on the measurement result of the serving cell.
10. The apparatus according to claim 9 , wherein the method further comprises:
determining that a second measurement reporting condition is met;
sending third information to the network device; and
receiving fourth information from the network device, wherein the fourth information indicates to enter a normal measurement state of the serving cell.
11. The apparatus according to claim 10 , wherein the second measurement reporting condition comprises that the measurement result of the serving cell meets a second threshold within a second duration.
12. The apparatus according to claim 9 , wherein the method further comprises:
determining to enter a normal measurement state of the serving cell after a third duration.
13. The apparatus according to claim 12 , wherein the second information further indicates the third duration.
14. The method according to claim 1 , wherein the measurement result comprises a reference signal received power, reference signal received quality, or a signal to interference plus noise ratio.
