Abstract

Embodiments of the present invention 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 method for enhancing measurement, the method comprising:

obtaining, by a user equipment (UE), 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;

a signal to interference plus noise ratio being

2. The method according to claim 1, wherein before obtaining the measurement amount, the method further comprises:

receiving, by the UE, a message carrying measurement configuration and sent by the base station; and

performing measurement configuration, by the UE according to the message, wherein the measurement configuration comprises one or more pieces of the following information;

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

3. The method according to claim 1, wherein the measurement period is a measurement period associated with one or more of measurement accuracy, power consumption of the UE, and a reference signal periodicity.

4. User equipment (UE) for enhancing measurement, the UE comprising:

a processor; and

a non-transitory computer readable storage medium having computer-executable instructions stored thereon, the computer-executable instructions, when executed by the processor, causing the processor to;

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

a signal to interference plus noise ratio being

5. The apparatus according to claim 4, wherein the processor is further configured 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 pieces 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 the UE, and a reference signal periodicity.
