Description
Technical field
The present invention relates to moving communicating field, especially relate to a kind of portable terminal and method for controlling downlink power.
Background technology
In mobile communication system, the strong signal suppressing of near-earth far weak signal produces " near-far interference ", and the channel capacity of system mainly is subject to the co-channel interference of other system or intrasystem other users' interference.Therefore, the transmitting power of necessary real time altering base station can guarantee communication quality, and this process is exactly the descending power control of communication system transmitting power, by descending power control, can improve channel capacity.
As shown in Figure 1, in the descending control of base station transmitting power, can adopt the power control mode of closed loop, under this control model, power control is divided into inner-loop power control and external circule power control.Described external circule power control, its objective is by actual signal quality (being the Block Error Rate estimated value) and compare with professional required target signal qualities (being block error probability desired value) to monitoring, obtain the signal interference ratio desired value of a real-time update, and this signal interference ratio desired value is configured to the use of inner-loop power control process; Described inner-loop power control, signal interference ratio according to current measurement, and several signal-to-interference ratio measurement values of past, predict the signal interference ratio of next subframe, and by comparing the signal interference ratio desired value that signal interference ratio predicted value and external circule power control provide, draw the power control command word of adjusting about power, this power control command word is sent to the base station by upward signal, the base station is regulated transmitting power according to this power control command word.
Above-mentioned is Poewr control method under the single CCTrCH (coded composite transport channel), in portable terminal, exist a plurality of (herein, when a plurality of being meant more than two and two) CCTrCH is professional, if they are not at same time slot, basically do not have mutual interference so between them, system can finish the power control for each CCTrCH respectively.But, closed-loop power control has the advantages that the control effect of the transmitting power on a certain direction (upstream or downstream) to be depended on the link-quality of other direction (downlink or uplink), when described a plurality of CCTrCH are present in same time slot, make in a certain direction (downlink or uplink) when having a plurality of CCTrCH, might be according to the requirement difference of portable terminal to professional Qos, the adjustment direction of the transmitting power of each CCTrCH is opposite, perhaps, speeding up of the transmitting power adjustment of a certain CCTrCH, can cause the signal receiving quality of other CCTrCH to worsen like this and can't recover, thereby cause call drop by closed-loop power control.
Particularly in HSDPA (high speed downlink packet access) process, because the discontinuity of SCCH (shared control channel), the base station might just be carried out open Loop Power control one time to SCCH at set intervals, because SCCH to the influence of the power control of DPCH (DPCH), can cause the downlink signal quality variation of DPCH.
