Power control method, power control system and related device

摘要

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.

1. A power control method, comprising:
monitoring, by a processor, a downlink data sending condition of a dedicated physical data channel (DPDCH) of a dedicated physical channel (DPCH); and if no downlink data is sent on the DPDCH, determining to decrease downlink transmit power of the DPCH, and adjusting power configuration information and triggering a base station to decrease the downlink transmit power of the DPCH according to the adjusted power configuration information, or if downlink data is sent on the DPDCH, determining to increase or maintain the downlink transmit power of the DPCH, and adjusting the power configuration information and triggering a base station to increase or maintain the downlink transmit power of the DPCH according to the adjusted power configuration information; wherein the DPCH comprises the DPDCH and a dedicated physical control channel (DPCCH), and the power configuration information comprises a maximum downlink transmit power value of the DPDCH or an initial downlink transmit power value of the DPDCH.
