Abstract

A power control method includes: receiving a protocol data unit (PDU) session establishment request sent by a terminal device; determining a target service type carried by a PDU session corresponding to the PDU session establishment request according to a data type tag carried by the PDU session establishment request; determining a target receiving power corresponding to the target service type according to the target service type and a configured receiving power of a base station; sending the target receiving power corresponding to the target service type to the terminal device.

First claim

What is claimed is:

1 . A power control method, performed by a terminal device, comprising:
sending at least one protocol data unit (PDU) session establishment request to a base station, wherein each of the at least one PDU session establishment request carries a data type tag; obtaining a target receiving power corresponding to each target service type sent by the base station; wherein the target receiving power is determined by the base station according to a power adjustment value corresponding to the target service type and a configured receiving power, wherein the power adjustment value is determined by the base station according to a priority corresponding to the target service type, and the target service type is determined by the base station according to the data type tag; and determining a target transmission power corresponding to a service of each target service type executed by a terminal device, according to each target receiving power and a maximum transmission power of the terminal device, wherein determining the target transmission power comprises: determining a candidate transmission power of the terminal device corresponding to each target service type, according to the target receiving power; and when the sum of each candidate transmission power is greater than the maximum transmission power, determining a proportion of each candidate transmission power to the sum of each candidate transmission power, and obtaining the corresponding target transmission power by multiplying the proportion of the candidate transmission power by the maximum transmission power.

2 . The method according to claim 1 , wherein determining the target transmission power further comprises:
when a sum of respective candidate transmission power is less than or equal to the maximum transmission power, determining the candidate transmission power of the terminal device corresponding to each target service type as the target transmission power of the terminal device corresponding to each target service type.

3 . A terminal device, comprising:
a processor; and a memory communicatively connected to the processor and storing non-transitory computer-readable instructions that, when executed by the processor, control the processor to: send at least one protocol data unit (PDU) session establishment request to a base station, wherein each of the at least one PDU session establishment request carries a data type tag; obtain a target receiving power corresponding to each target service type sent by the base station; wherein the target receiving power is determined by the base station according to a power adjustment value corresponding to the target service type and a configured receiving power, wherein the power adjustment value is determined by the base station according to a priority corresponding to the target service type, and the target service type is determined by the base station according to the data type tag; and determine a target transmission power corresponding to a service of each target service type executed by a terminal device, according to each target receiving power and a maximum transmission power of the terminal device, wherein the memory further storing instructions that, when executed by the processor, control the processor to: determine a candidate transmission power of the terminal device corresponding to each target service type, according to the target receiving power; and when the sum of each candidate transmission power is greater than the maximum transmission power, determine a proportion of each candidate transmission power to the sum of each candidate transmission power, and obtain the corresponding target transmission power by multiplying the proportion of the candidate transmission power by the maximum transmission power.

4 . The terminal device according to claim 3 , wherein the memory further storing instructions that, when executed by the processor, control the processor to:
when a sum of respective candidate transmission power is less than or equal to the maximum transmission power, determine the candidate transmission power of the terminal device corresponding to each target service type as the target transmission power of the terminal device corresponding to each target service type.
