Abstract

Embodiments of the present disclosure provide a method and an apparatus for enhancing measurement in a wireless communication system. The method includes: obtaining, according to a measurement period or triggered by an event, a measurement amount, where the measurement amount includes a ratio of a valid signal based on a reference signal to a non-valid signal based on the reference signal measured based on the reference signal; reporting the measurement amount to a base station; or performing cell selection or cell reselection according to the measurement amount.

Claims

1. A non-transitory computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to:

obtain, according to a measurement period, a measurement amount comprising a signal to interference plus noise ratio (SINR) based on a reference signal, wherein the SINR comprises;

2. The non-transitory computer-readable storage medium according to claim 1, wherein before obtaining the measurement amount, the instructions, when executed by the computer, cause the computer to:

receive a message carrying measurement configuration and sent by the base station; and

perform measurement configuration, according to the message, wherein the measurement configuration comprises one or more of the following information;

reporting configuration information, a filtering coefficient, a measurement bandwidth, a measurement frequency range, or a measurement period.

3. The non-transitory computer-readable storage medium according to claim 1, wherein the measurement period is a measurement period associated with one or more of:

measurement accuracy, power consumption of a user equipment (UE), and a reference signal periodicity.

4. An apparatus comprising:

at least one processor; and

at least one storage medium storing instructions which, when executed by the processor, cause the apparatus to;

obtain, according to a measurement period, a measurement amount comprising a signal to interference plus noise ratio (SINR) based on a reference signal, wherein the SINR comprises;

5. The apparatus according to claim 4, wherein the instructions, when executed by the processor, further cause the apparatus to:

before the measurement result is obtained according to the measurement period, receive a message carrying measurement configuration and sent by the base station; and

perform measurement configuration according to the message, wherein the measurement configuration comprises one or more of the following information;

reporting configuration information, a filtering coefficient, a measurement bandwidth, a measurement frequency range, or a measurement period.

6. The apparatus according to claim 4, wherein the measurement period is a measurement period associated with one or more of:

measurement accuracy, power consumption of a user equipment (UE), and a reference signal periodicity.
