Abstract

The invention discloses a method and a device for configuring transmitted power, wherein the method for configuring the transmitted power comprises the following steps of: calculating the power parameters of all physical uplink shared channels (PUSCH); judging whether PUSCHs the power parameters of which are larger than a threshold value exist or not; if so, setting the transmitted power of at least a part of the PUSCHs to be 0; judging whether the summation of the estimated transmitted power of the PUSCHs the transmitted power of which is not set to be 0 and the estimated transmitted power of a physical uplink control channel (PUCCH) is larger than the maximum configuration output power of user equipment or not; and if not, setting the transmitted power of the PUSCHs the transmitted power of which is not set to be 0 to be the estimated transmitted power of the PUCCH. The invention solves the problem that the transmitted power of all physical uplink channels on component carriers cannot be configured in the prior art and effectively reduces the transmitted power of all the physical uplink channels.

Description

technical field

[0001] The invention relates to the field of mobile communication, in particular to a method and device for configuring transmission power. Background technique

[0002] In the 3GPP LTE (The 3rd Generation Partnership Project Long Term Evolution, 3rd Generation Partnership Project Long Term Evolution) system, uplink power control (Uplink Power Control, referred to as uplink power control or power control) is used to control the physical uplink channel (Uplink Physical Channel) to compensate for path loss and shadowing of the channel, and suppress inter-cell interference. Wherein, the physical uplink channel controlled by the uplink power control includes a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), a physical uplink control channel (Physical Uplink Control Channel, PUCCH) and a measurement reference signal (Sounding Reference Signal, SRS). LTE uplink power control adopts a control method combining open loop (Open Loop) and closed...
