Problems solved by technology

[0003] The existing 3GPP agreement stipulates that when the terminal sends uplink data on the E-DPDCH channel, the E-DPCCH and DPCCH channels will be sent together; and when the terminal has no data to send on the E-DPDCH channel, the E-DPCCH channel will not transmission, but the DPCCH channel will still continue to transmit, which will bring additional interference and reduce the uplink system capacity and reduce the standby time of the terminal

Abstract

Provided are a power control method and device, and a base station. The method comprises: when the service type of a user equipment is a pre-designated service type, acquiring an HARQ process activation / deactivation mark of the user equipment; and in a deactivated HARQ process corresponding to the HARQ process deactivation mark of the user equipment, adjusting at least one of the power control related parameters, so as to reduce the transmitting power of the user equipment. By implementing the embodiments of the present invention, when a certain HARQ process is deactivated, the base station can notify the user equipment to reduce the transmitting power, so as to reduce the uplink interference, thereby increasing the uplink capacity of a system, reducing unnecessary power waste and improving the standby time of the user equipment.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a power control method, device and base station. Background technique [0002] The uplink dedicated physical channels of the HSUPA (High Speed ​​Uplink Packet Access) service in UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System) include: Dedicated Physical Control Channel (Dedicated Physical Control Channel, DPCCH), It mainly provides control information such as Pilot, TPC, TFCI, and FBI; the enhanced dedicated physical control channel (E-DCH Dedicated Physical Control Channel, E-DPCCH) is mainly responsible for transmitting the control part of the HSUPA service and the enhanced dedicated physical data channel (E-DCH Dedicated Physical Control Channel, E-DPDCH), is mainly responsible for transmitting the data part of the HSUPA service. [0003] The existing 3GPP agreement stipulates that when the terminal sends uplink d...
