Step 201: Obtain PHR configuration information of the BWP supported by the user terminal.

The BWP supported by the user terminal may be one or more BWPs supported by the user terminal. For example, the user terminal may only support a relatively small working bandwidth (such as 5 MHz, 10 MHz, or 20 MHz, etc.), and one cell on the network side. It will support a relatively large bandwidth (such as 100MHz, 200MHz or 400MHz, etc.), so that the BWP supported by the above user terminal can be one or more BWPs in the bandwidth of the cell.

In addition, the foregoing acquisition may be sent by the receiving base station, or may be pre-defined by a protocol, or the user terminal may be pre-stored or the like. In addition, the foregoing PHR configuration information may indicate a BWP that needs to report a power headroom and/or a maximum transmit power of the terminal, and may also indicate a trigger condition reported by the user terminal PHR, and may also indicate a content that the BWP needs to report, etc. The disclosed embodiments are not limited.

Step 202: Report a PHR to the base station according to the PHR configuration information, where the PHR includes a power headroom of the BWP indicated by the PHR configuration information and/or a maximum transmit power of the terminal.

In addition, the BWP indicated by the PHR configuration information may be one or more BWPs supported by the user terminal. The power headroom reported by each BWP and/or the maximum transmit power of the terminal may be reported in the same manner or in different manners.

In addition, if there are multiple BWPs that need to be reported to the PHR, the user terminal can upload the corresponding PHR for each BWP, so that the corresponding PHR can be reported in different BWPs, thereby achieving more accurate power control for each BWP, thereby saving The transmit power of the UE and improve the signal quality of the uplink transmission. Of course, the embodiment of the present disclosure does not limit this. For example, power information of multiple BWPs may be reported by the same PHR.

In this embodiment, the PHR configuration information of the bandwidth part BWP supported by the user terminal is obtained, and the PHR is reported to the base station according to the PHR configuration information, where the PHR includes the power balance of the BWP indicated by the PHR configuration information. And / or terminal maximum transmit power. In this way, the PHR is reported at the BWP level, so that the accuracy of the uplink power of the user terminal can be improved.

Of course, in this embodiment, the step 301 is optional, and the step 301 is to be used to obtain the PHR configuration information of the BWP supported by the user terminal, for example, obtaining the PHR configuration information of the BWP supported by the user terminal. Can include:

Obtain PHR configuration information of the BWP supported by the user terminal as agreed in the protocol.

The PHR configuration information that is obtained by the protocol may be obtained by acquiring pre-stored PHR configuration information. In this implementation manner, the foregoing PHR configuration information can be obtained through a protocol, so that signaling transmission overhead before the user terminal and the base station can be reduced. Of course, step 301 can also be directly replaced with obtaining PHR configuration information of the BWP supported by the user terminal.

Optionally, the PHR configuration information includes at least one of the following:

What content needs to be reported, such as the maximum transmit power of the terminal and/or the power headroom after the uplink physical channel is sent, so that the user terminal can be flexibly instructed to perform PHR reporting, so that the flexibility of the user terminal can meet the requirements of different services. The format of the PHR indicated by the implicit indication may be a format indicating the PHR through the configuration attribute of the BWP or the parameter of the BWP, and the PHR format of the BWP may be determined by the user terminal by using the configuration attribute or the parameter.
