SINR ESTIMATION METHOD AND DEVICE

CROSS-REFERENCE TO RELATED APPLICATION

The present disclosure claims the priority benefit of U.S. Provisional Patent Application No. 62/910,722, filed October 4, 2019, the disclosure of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the field of wireless communication technologies, and more particularly, to a SINR estimation method and device.

BACKGROUND

NR (New Radio) /5G system supports SINR (Signal to Interference Noise Ratio) measurement based on SS (Synchronization Signal) /PBCH (Physical Broadcast Channel) blocks or CSI-RS (Channel State Information Reference Signal) resources. The SINR is defined as the ratio between the signal power and the noise power + the interference power.

However, the method of measuring SINR on SS/PBCH block or CSI-RS resource supported in NR system only works if the UE (User Equipment) is not configured with dedicated reference signal resource for interference measurement. And the method does not support the SINR measurement with dedicated UE-specific interference measurement. Such SINR measurement is only applicable for limited deployment scenarios. Thus, defining new SINR measurement with dedicated interference measurement RS resource is needed.

The 3GPP (3 ^rd Generation Partnership Project) release 15 specification supports SINR measurement on SS/PBCH block or CSI-RS resource without dedicated reference signal resource for interference measurement. The SINR measured from a SS/PBCH block is defined in Table 1.

The SINR measured from a CSI-RS resource is defined in Table 2.

As specified, the UE measures the signal power by measure the signal of SSS signal and measures the power of interference and noise by measuring the signal residual from the REs carrying SSS signals.

The reporting range of SINR of SS/PBCH is also specified in the following Table 3.

The L1-SINR beam measurement that will be specified in release 16 is based on CSI-RS resource for beam management. The CSI-RS resource for beam management has one or two antenna ports.

The method of measuring SINR on SS/PBCH block or CSI-RS resource supported in NR system only works if the UE is not configured with dedicated reference signal resource for interference measurement. The UE only measures both signal power and interference power from the SS/PBCH block or CSI-RS resource configured for channel measurement. Such SINR measurement is only applicable for limited deployment scenarios. The method does not support the SINR measurement with dedicated UE-specific interference measurement. Particularly, 3GPP release 16 is going to specify SINR measurement with dedicatedly configured reference signal resource for interference measurement to support more advanced multi-beam measurement. Thus, defining new SINR measurement with dedicated interference measurement RS (Reference Signal) resource is needed.

With reference to the accompanying drawings, a SINR estimation method and equipment provided by the embodiments of the present disclosure will be specifically described below.

If the first CSI-RS is configured with one antenna ports, the signal power is equal to the linear power of the REs carrying CSI reference signal. If the first CSI-RS is configured with two antenna ports, the signal power is equal to the sum of the linear power of the REs of a first antenna port carrying CSI reference signal and the linear power of the REs of a second antenna port carrying CSI reference signal, i.e., the signal power is equal to 2× (the linear average over the power contribution of the REs carrying CSI reference signal) .
