Description

Double-current inner ring link adaptive approach and system
Technical field
The present invention relates to the communications field, relate to a kind of double-current inner ring link adaptive approach and system particularly.
Background technology
3G (Third Generation) Moblie partner program (3GPP) with the D-TxAA standardization as multiple-input and multiple-output (MIMO) technology under the Frequency Division Duplexing (FDD) (Frequency Division Duplex, be called for short FDD).In 2 * 2 MIMO D-TxAA technology, terminal (UserEquipment, be called for short UE) according to Common Pilot Channel (Common Pilot Channel, abbreviation CPICH) situation determines the main precoding vectors precoding control indication (PCI) of a first-selection and channel quality indication (Channel quality instruction is called for short CQI) to feed back to base station (Node B) together.Wherein, CQI comprises two types, and a kind of is type (type) A CQI report, and a kind of type B CQI of being reports.Type A CQI report can comprise 1 transformat or 2 transformats, and this depends on the transmission block number of the current selection of UE.Type B CQI report includes only 1 transformat.
For type A CQI report, its report speed is the N/M of available CQI report speed, and the remaining type B CQI that is used for reports, is 1/2,2/3 according to 3GPP agreement TS25.433v8.3.0 regulation N/M value, 3/4,4/5,5/6,6/7,7/8,8/9,9/10,1/1.In addition, type A CQI report calculates according to following formula:
CQI=15xCQI when preferred 2 transmission blocks of terminal 1+ CQI 2+ 31,
CQI=CQI when preferred 1 transmission block of terminal S
Double-current CQI in the type A CQI report adopts every stream 4 bits (bit) feedback.CQI feedback is to calculate letter according to supposition UE HS-PDSCH channel received power mean allocation on 15 code channels to disturb and make an uproar than (Signal to Interference plus Noise Ratio is called for short SINR), searches CQI then and shows acquisition.According to 3GPP agreement TS25.214v8.4.0, additive white Gaussian noise (the Additive WhiteGaussian Noise that an equivalence is arranged in double-current CQI table, be called for short AWGN) the SINR difference DELTA, the SINR that this value representation is current and send to specify the transmission block of size to reach difference between the SINR that BLER need to require under awgn channel, UE tells the channel conditions that the base station is current by this difference DELTA among this CQI.
When dispatched UE the base station, the stream number that the UE that need be scheduled according to the PCI/CQI decision of UE feedback and this UE can send and each flowed corresponding transformat.When double fluid was selected, the base station was not carried out precoding according to the code value that prelists in the PCI feedback to two flow points, and the precoding weights of employing are handed down to UE by High-Speed Shared Control Channel (HighSpeed Shared Control Channel is called for short HS-SCCH).When the base station sent double fluid to UE, double fluid adopted identical code channel number and transmitted power.The modulation coding mode that stream number, code channel number and every stream adopt is handed down to UE by HS-SCCH.As base station high speed physical down link sharing channel (High Speed Physical DownlinkShared Channel, be called for short HS-PDSCH) when transmitted power does not reach the power that carries out the supposition of CQI feedback or available HS-PDSCH code channel and does not have 15, the base station need be to transmitted power, and code channel number and modulation coding mode are adjusted.Equally, when data are not enough in the UE buffer area that is scheduled in the base station, also need transmitted power, code channel number and modulation coding mode are adjusted.At last, when the AWGN SINR difference DELTA of the corresponding equivalence of the CQI of two streams value is inequality, also need to adjust the transmitted power of base station to this UE.
Also do not see at present relevantly under 2 * 2 MIMO D-TxAA, carry out the inner ring link self adaptation and promptly adjust transmitted power, the specific implementation method of code channel number and modulation coding mode.
