Description
Technical field
The present invention relates to down high-speed data transmission (HSDPA) technology, particularly relate to a kind of method and apparatus of in the HSDPA system, realizing power control.
Background technology
At present, the HSDPA system because its two-forty, low postpone, advantage such as user experience is good, obtained application widely.In the HSDPA system,, shared control channel (HS-SCCH) and shared indicating channel (HS-SICH) have been defined in order to guarantee the transfer of data of base station (Node B) and user terminal (UE).Wherein, HS-SCCH is a down physical layer control channel, the base station by this HS-SCCH to the necessary control information of decoding of user terminal transmitting downlink data.HS-SICH is a up link, user terminal mainly is to be the feedback information (CQI) of mixed self-adapting re-transmission (HARQ) desired affirmation (ACK)/non-affirmation (NACK) information and downlink quality to replying of transmission grouping by the feedback control information of this HS-SICH to base station transmits necessity.
The HSDPA system belongs to a kind of code division multiple access system, that is to say, the HSDPA system is a kind of interference-limited system, and the big young pathbreaker of interference directly has influence on the performance of system.And the interference major part in the HSDPA system derives from the transmitting power of user terminal in the system, if control the transmitting power of user terminal effectively, then can reduce interference, improves systematic function.Therefore, in the HSDPA system, in order to reduce interference, the HS-SICH that user terminal is used has carried out power control.
In the HSDPA system, when the HS-SICH that user terminal is used realizes power control, for the power that makes HS-SICH not only satisfies the requirement that reduces the requirement of disturbing but also can also farthest satisfy system transmissions, the system that makes reaches the overall performance optimum, then must consider the correlation of each time of HS-SICH transmission.That is to say, if the correlation of each time of HS-SICH transmission is bigger, so, the transmitting power when SS later is used HS-SICH should be with reference to the situation of using HS-SICH before, that is to say, should use the closed-loop power control mode that HS-SICH is realized power control.If the correlation of each time of HS-SICH transmission is less, so, the transmitting power when SS later is used HS-SICH then should not that is to say again with reference to the situation of using before HS-SICH, should use the open loop power control mode that HS-SICH is realized power control.
At present, HS-SICH is realized a kind of mode of power control is: when the not free interval of each time of HS-SICH transmission, can determine that the correlation of each time of HS-SICH transmission is very big, HS-SICH is carried out closed-loop power control; When the free interval of each time of HS-SICH transmission, owing to can't polarize the size of each time of HS-SICH transmission correlation, therefore, HS-SICH is carried out closed-loop power control add the open loop power control, that is to say that the base station can be sent to user terminal with the power indication, user terminal not only carries out closed-loop power control according to the power indication that receives to the data of transmitting on HS-SICH, but also the data of transmitting on HS-SICH are carried out the path loss compensation deals, to satisfy the requirement of open loop power control.
As seen, in existing processing to the control of HS-SICH realization power, if the free interval of each time of HS-SICH transmission, so, user terminal will carry out closed-loop power control to HS-SICH and add the open loop power control, and does not consider the correlation of each time of HS-SICH transmission in the practical business realization.Like this, then can cause system to decide the power control mode that HS-SICH is taked according to true correlation and system's self performance demand of each time of HS-SICH transmission, that is to say, uncontrollable HS-SICH carries out the opportunity of open loop power control and the opportunity of closed-loop power control, thereby make system flexibility relatively poor, greatly reduce QoS.
In addition, in prior art, as long as each time of HS-SICH transmission is at interval free, then must carry out the processing mode that closed-loop power control adds the open loop power control to HS-SICH, can make that also user terminal is inaccurate to the power control mode that HS-SICH carried out, such as, under the situation that channel variation compares comparatively fast or each time of HS-SICH Transmission Time Interval is bigger, each time of HS-SICH transmission is independently, realizes that with reference to the transmission last time power control then can cause power control inaccurate, therefore, should not use closed-loop power control, only use open loop power control proper, and under other service environments, only use closed-loop power control proper.As seen, prior art blindly uses closed-loop power control to add the mode of open loop power control, also can't carry out power control accurately to HS-SICH, thereby greatly reduce the performance of system.
