Control method for power configuration on heterogeneous network, and user equipment

摘要

The present application provides a control method for power configuration on a heterogeneous network, and a user equipment. The control method for power configuration includes: determining whether the user equipment is in a soft handover area, in which a macro base station is used as a serving base station, between uplink and downlink balance points; when the user equipment is in the soft handover area, in which the macro base station is used as the serving base station, between the uplink and downlink balance points, increasing power of a dedicated physical control channel, so that the serving base station can normally receive a signal from the user equipment; and adjusting a power offset of an enhanced dedicated physical data channel to a first power offset, where the first power offset is any value in a flat area of an optimal power offset of the user equipment.

1. A control method for power configuration on a heterogeneous network, comprising:
increasing, by a user equipment, power of a dedicated physical control channel between uplink and downlink balance points when the user equipment is in a soft handover area in which a macro base station is used as a serving base station; and adjusting a power offset of an enhanced dedicated physical data channel to a first power offset PO1, wherein the first power equals (SIR0/SIR1)×(PO0+POw)−POw, wherein SIR0 is an initial signal-to-noise ratio target value of the dedicated physical control channel when the user equipment is not in the soft handover area, SIR1 is an adjusted first signal-to-noise ratio target value of the dedicated physical control channel when the user equipment is in the soft handover area, PO0 is an initial power offset of the enhanced dedicated physical data channel when the user equipment is not in the soft handover area, and wherein POw is the sum of power offsets of a high speed dedicated physical control channel, an enhanced dedicated physical control channel, a dedicated physical data channel, and the dedicated physical control channel when the user equipment is not in the soft handover area.
