The embodiments of the present disclosure will now be further described with reference to the accompanying drawings and specific implementation modes.

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with embodiments of the present disclosure. Rather, they are merely examples of apparatus and methods consistent with aspects of the disclosure as detailed in the appended claims.

It should be noted that an embodiment of the present disclosure may include multiple steps; for convenience of description, these steps are numbered; however, these numbers do not limit the execution time slots and execution order between the steps; these steps It can be implemented in any order, and the embodiment of the present disclosure does not limit this.

In the description of this application, words such as "first", "second" and "third" are only used for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying. order. "Plural" means two or more.

"And/or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and/or B can mean: A exists alone, A and B exist simultaneously, and B exists alone.

The power control accuracy is related to the implementation of the terminal. Although some terminals have higher power control accuracy, there is no distinction in the existing protocols. That is, the network side adopts the same power control strategy for all terminals, which will lead to some terminals with higher power control accuracy. The advantages of terminals with higher power control accuracy cannot be brought into play, thus affecting the overall performance of the system.

Therefore, in order to differentiate the power control accuracy of terminals and better leverage the advantages of terminals with higher power control accuracy, the present disclosure provides a power control method.

Embodiments of the present disclosure provide a power control method, which is applied to network equipment. Figure 1 is a flow chart of a power control method according to an exemplary embodiment. As shown in Figure 1, the method includes:

Step 101: Receive indication information sent by the user equipment, where the indication information is used to indicate the power control accuracy of the user equipment;

Step 102: Determine power control parameters for the user equipment based on the indication information.

In one embodiment, the network device receives indication information from the user equipment, the indication information is used to indicate the power control accuracy of the user equipment, and then the network device determines the power control accuracy for the user equipment based on the power control accuracy indicated by the indication information. Power control parameters. That is, different power control parameters are used for user equipment with different power control accuracy.

Exemplarily, the indication information is information with one bit. For example, when the one bit has a value of 1, it indicates that the power control accuracy of the user equipment is the first power control accuracy, that is, the user equipment has higher power control accuracy; When the value of this one bit is 0, it indicates that the power control accuracy of the user equipment is the second power control accuracy, that is, the user equipment has a lower power control accuracy. Among them, the first power control accuracy is higher than the minimum power control accuracy defined in the current communication protocol.

It should be noted that the power control accuracy here refers to the allowable error between the uplink transmit power of the user equipment and the target power. If the power control accuracy is high, it means that the allowable error between the user equipment's uplink transmit power and the target power is small; if the power control accuracy is low, it means that the allowable error between the user equipment's uplink transmit power and the target power is large.

For example, the power control parameter may be a threshold value for determining whether to reduce the uplink transmission power of the user equipment, a threshold value for determining whether to increase the uplink transmission power of the user equipment, and a step for adjusting the uplink transmission power of the user equipment. long.

In the above embodiment, the user equipment sends indication information indicating its own power control accuracy to the network device. Based on the indication information, the network device obtains the power control accuracy of the user equipment, and for the power control accuracy of the user equipment, The user equipment determines power control parameters. As a result, user equipment with higher power control accuracy can take advantage of its advantages, that is, it can not only ensure the quality of uplink transmission signals, but also minimize interference and reduce power consumption.

Embodiments of the present disclosure provide a power control method, which is applied to network equipment. Figure 2 is a flow chart of a power control method according to an exemplary embodiment. As shown in Figure 2, the method includes:

That is, for user equipment with higher power control accuracy and user equipment with lower power control accuracy, different threshold values are used to determine whether to reduce the uplink transmission power and whether to increase the uplink transmission power.

Wherein, when determining whether the user equipment reduces the uplink transmit power, the first reduction power threshold value for the user equipment with higher power control accuracy is smaller than the second reduction threshold value for the user equipment with lower power control accuracy. Power threshold. When determining whether the user equipment increases the uplink transmit power, the first increase power threshold for user equipment with higher power control accuracy is greater than the second increase power threshold for user equipment with lower power control accuracy. limit.

As mentioned above, the first power reduction threshold value is used to determine whether to reduce the uplink transmit power of the user equipment with the first power control precision, and the first power increase threshold value is used to determine whether to increase the uplink transmission power of the user equipment with the first power control precision. The uplink transmit power of the user equipment is controlled accurately, so the first reduced power threshold is greater than the first increased power threshold. Similarly, the second power reduction threshold value is used to determine whether to reduce the uplink transmit power of the user equipment with the second power control precision, and the second power increase threshold value is used to determine whether to increase the uplink transmission power of the user equipment with the second power control precision. The uplink transmit power of the user equipment is accurate, so the second reduced power threshold is greater than the second increased power threshold.

In one implementation, the first reduced power threshold is one of the following: a first reduced power signal to interference plus noise ratio (SINR) threshold, a first reduced power threshold The power signal to interference ratio (Signal to Interference Ratio, SIR) threshold and the first reduced power signal to noise ratio (Signal to Noise Ratio, SNR) threshold, the first increased power threshold is one of the following : the first increasing power SINR threshold, the first increasing power SIR threshold and the first increasing SNR threshold; and the second decreasing power threshold is one of the following: the second decreasing The power SINR threshold, the second reduced power SIR threshold and the second reduced power SNR threshold, the second increased power threshold is one of the following: the second increased power SINR threshold , the second increased power SIR threshold value and the second increased power SNR threshold value.
