Abstract

The invention discloses a power control method, a power control system and related equipment. The power control method comprises the following steps: monitoring a data sending condition of a downlink of a DPDCH (Dedicated Physical Data Channel); if no data is sent by the downlink of the DPDCH, confirming reduction of the transmission power of the downlink of the DPDCH; or if data is sent by the downlink of the DPDCH, confirming increase or maintenance of the transmission power of the downlink of the DPDCH. Under the condition of ensuring the property of a system, the transmission power of the downlink of the DPDCH is reduced and the other user experiences are increased according to the power control method provided by the invention.

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...
