Title: METHOD AND DEVICE FOR CONTROLLING UPLINK POWER
Abstract:
The present invention relates to the field of communications. Embodiments of the present invention provide a method and a device for controlling uplink power, which can overcome a problem in prior art that may cause PUSCH sending power after rollback to be improper and thus affect system performance. The method comprises: a UE obtaining a power rollback parameter and obtaining first PUSCH sending power and second PUSCH sending power, wherein the power rollback parameter comprises a power rollback scaling factor, or the power rollback parameter comprises a first interference value and a second interference value; if a sum of the first PUSCH sending power and the second PUSCH sending power exceeds a maximum sending power of the UE, rolling back the first PUSCH sending power and the second PUSCH sending power based on the first interference value and the second interference value, or rolling back the first PUSCH sending power and the second PUSCH sending power based on the power rollback scaling factor.
