Abstract

The present invention discloses a power control method, a power control system and a related device. The method includes: monitoring a downlink data sending condition of a dedicated physical data channel (DPDCH), and if no downlink data is sent on the DPDCH, determining to decrease downlink transmit power of a DPCH, or if downlink data is sent on the DPDCH, determining to increase or maintain downlink transmit power of a DPCH. The present invention can reduce the downlink transmit power of the DPCH and promote experience of other users on a precondition of ensuring system performance.

Description

technical field [0001] The invention relates to power control technology in a mobile communication system, in particular to a power control method, a power control system and related equipment. Background technique [0002] When the downlink service of the packet switching (PS, Packet Switching) domain is carried on the high speed downlink packet access (HSDPA for short), each HSDPA user needs to be assigned a Dedicated Physical Channel (Dedicated Physical Channel). The Physical Channel, hereinafter referred to as the DPCH channel, is used for inner loop power control and signaling radio bearer (Signal Radio Bearer, hereinafter referred to as SRB). [0003] The DPCH includes a dedicated physical data channel (Dedicated Physical Data Channel, hereinafter referred to as DPDCH) and a dedicated physical control channel (Dedicated Physical Control Channel, hereinafter referred to as DPCCH), and these two channels are multiplexed together and delivered. figure 1 It shows the fram...
