Uplink power controlling is the key technology of TD-LTE system air interface, users can set different uplink transmission power for different channel according to power control parameters. This paper frst introduces the TD-LTE system architecture and the basic concept of uplink power controlling; Then uplink power controlling is introduced in detail in three ways: uplink shared channel PUSCH power control, uplink control channel PUCCH power control and SRS power control; Finally this paper gives performance simulation for the uplink power control algorithm and a brief analysis of the results.
