Abstract

Claims (44)

1. An open-loop power control method, comprising:

receiving, by a terminal, transmitted power configuration information, wherein the transmitted power configuration information comprises a first path loss compensation factor and a second path loss compensation factor;

determining, by the terminal, a target path loss compensation factor based on the transmitted power configuration information, wherein the target path loss compensation factor is one of the first path loss compensation factor and the second path loss compensation factor; and

controlling, by the terminal, a transmitted power of the terminal based on the target path loss compensation factor;

wherein determining, by the terminal, the target path loss compensation factor based on the transmitted power configuration information comprises:

determining, by the terminal, the target path loss compensation factor based on the transmitted power configuration information and a path loss value measured by the terminal;

or

determining, by the terminal, the target path loss compensation factor based on the transmitted power configuration information and a type of a reference signal, wherein the reference signal is used to determine a path loss value between the terminal and an access network device;

or

determining, by the terminal, the target path loss compensation factor based on the transmitted power configuration information and a type/types of a channel/signal through which the terminal transmits data.

2. The method according to claim 1 , wherein determining, by the terminal, the target path loss compensation factor based on the transmitted power configuration information and the path loss value measured by the terminal comprises:

determining the first path loss compensation factor as the target path loss compensation factor, wherein the path loss value is not greater than a path loss threshold; or,

determining the second path loss compensation factor as the target path loss compensation factor, wherein the path loss value is greater than a path loss threshold;

wherein a value of the first path loss compensation factor is smaller than a value of the second path loss compensation factor.

3. The method according to claim 2 , further comprising:

receiving, by the terminal, the path loss threshold from an access network device.

4. The method according to claim 1 , wherein determining, by the terminal, the target path loss compensation factor based on the transmitted power configuration information and the type of the reference signal comprises:

determining the first path loss compensation factor as the target path loss compensation factor, wherein the type of the reference signal comprises only an SSB; or,

determining the second path loss compensation factor as the target path loss compensation factor, wherein the type of the reference signal comprises an SSB, and at least one reference signal other than the SSB;

wherein a value of the first path loss compensation factor is smaller than a value of the second path loss compensation factor.

5. The method according to claim 1 , wherein determining, by the terminal, the target path loss compensation factor based on the transmitted power configuration information and the type/types of the channel/signal through which the terminal transmits data comprises:

determining the first path loss compensation factor as the target path loss compensation factor, wherein the type/types of the channel/signal is/are PUCCHs; or,

determining the second path loss compensation factor as the target path loss compensation factor, wherein the type/types of the channel/signal is/are non-PUCCHs;

wherein a value of the first path loss compensation factor is smaller than a value of the second path loss compensation factor.

6. A non-transitory computer readable storage medium, wherein instructions in the computer readable storage medium are executed by a processor to implement an open-loop power control method according to claim 1 .

7. A terminal, comprising:

control a transmitted power of the terminal based on the target path loss compensation factor;

wherein when determining the target path loss compensation factor based on the transmitted power configuration information, the processor is further configured to:

determine the target path loss compensation factor based on the transmitted power configuration information and a path loss value measured by the terminal;

or

determine, by the terminal, the target path loss compensation factor based on the transmitted power configuration information and a type of a reference signal, wherein the reference signal is used to determine a path loss value between the terminal and an access network device;

or

determine, by the terminal, the target path loss compensation factor based on the transmitted power configuration information and a type/types of a channel/signal through which the terminal transmits data.

8. The terminal according to claim 7 , wherein when determining the target path loss compensation factor based on the transmitted power configuration information and the path loss value measured by the terminal, the processor is further configured to:
