Based on the system message and the downlink reference signal sent by the network device, perform power measurement to determine the path loss power; determine the open-loop transmission power based on the path loss power and the target received power; and adjust the open-loop transmission power based on the absolute difference value to Determine the transmit power.

If the power indication includes an absolute differential value, and the pre-configured power control mode is combined power control mode, the smart relay device needs to perform open-loop power control to determine the open-loop transmit power, and then perform closed-loop power control to The value adjusts the determined open-loop transmit power.

S4022. Adjust the preconfigured power based on the absolute difference value to determine the sending power.

If the power indication includes an absolute differential value, and the preconfigured power control mode is a closed-loop power control mode, the smart relay device needs to perform closed-loop power control to adjust the preconfigured power based on the absolute differential value.

Specifically, the power indication sent by the network device to the smart relay device includes an absolute difference value, and the smart relay device adjusts the preconfigured power according to the absolute value to determine the sending power when sending a signal.

In some embodiments, the preconfigured power is a default power value or an initial power value indicated by RRC signaling sent by the network device. The default power value may be a default maximum power value.

For example, the absolute difference value may always be a positive number, and the smart relay device subtracts the absolute difference value from the default power value to determine the transmission power.

As another example, the network device sends an initial power value to the smart relay device through RRC signaling, the absolute difference value can be positive or negative, and the smart relay device adds or subtracts the absolute difference value on the basis of the initial power value to determine the transmit power.

When the power indication includes the cumulative difference value, the above step S402 may be implemented through the following steps.

S4023. Adjust the currently available sending power based on the cumulative difference value to determine the sending power.

The power indication sent by the network device to the intelligent relay device includes the cumulative difference value. The network device determines that further power adjustment is required according to the power measurement result of the uplink signal, and then the network device sends transmission power control information including the cumulative difference value to the intelligent relay device.

If the power indication includes the cumulative differential value, no matter the pre-configured power control mode is the combined power control mode or the closed-loop power control mode, the smart relay device is based on the currently available transmit power (that is, the transmit power used in the last signal transmission) Make adjustments.

For example, when the power adjustment value is the cumulative difference value, the intelligent relay device adjusts according to the transmission power used in the last transmission signal, for example, the last time was P(i), then the next time is P(i+1)=P (i) +/- cumulative difference value.
