Abstract
The invention provides a method for controlling physical uplink shared channel transmission power. When the physical uplink shared channel only has uplink control information to transmit and does not have uplink shared channel data to transmit, the effect of transmission format is not considered when setting the transmission power of PUSCH; or the excursion parameter of the transmission format is zero; or the excursion parameter of the transmission format is set according to a channel quality indicating command expressed by TBS and a bit number comprised in the corresponding checking (CRC) of the TBS; or the excursion parameter of the transmission format is set according to the TBS and MPUSCH obtained in PDCCH when transmitting a transmission block originally in the last time. The invention solves the physical uplink shared channel power control problem when the physical uplink shared channel only has the uplink control information to transmit and does not have the uplink shared channel data to transmit, thereby ensuring the integral performance of a system.
