Abstract

The invention relates to the technical field of communication, and discloses a ULPC (Uplink Power Control) method and a ULPC device for an LTE (Long Term Evolution) system. The ULPC method for the LTE system comprises the following steps: monitoring the quality information of a user uplink channel, wherein the information comprises user uplink SINR (Signal Interference Noise Ratio) information which has been accessed in a communication device and received uplink SINR times; synthesizing single UE (User Equipment) and mentoring results of the UE in the same power control group to determine whether the user adopts the way of uplink and downlink authorization or power control group to carry out power adjustment; if yes, using the corresponding transmit mode to transmit power adjustment command words. According to the method and the device, power adjustment can be carried out when the system is free of business for a long time, and the spending of signaling resources can be reduced further.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method and device for uplink power control of an LTE system. Background technique [0002] In the LTE (Long Term Evolution) wireless communication system, the base station generally adjusts the power of the user terminal (User Equipment, UE) through closed-loop power control. The uplink transmit power obtained by power control is adjusted, so that the transmit power of the UE can be controlled more precisely. [0003] When there is uplink and downlink data, the power adjustment information of the UE is issued to the UE along with the uplink and downlink scheduling authorization, and the UE adjusts its uplink transmit power according to the received power adjustment information. However, when there is no uplink and downlink data to be scheduled for a long time or in semi-static scheduling, the base station has no uplink and downlink scheduling authorizatio...
