Description
Technical field
The present invention relates to a kind of information processing method, relate in particular to a kind of band-adaptive encoded traffic processing method, base station and terminal.
Background technology
(the WiMAX of World Interoperability for Microwave Access, WiMax system, World Interoperability for Microwave Access) adaptive coding (the Band AMC of midband, Band Adaptive Modulation And Coding) subchannel is a kind of special subchannel of physical layer, different with general subchannel is, its subcarrier that comprises is continuous on frequency domain, the measurement result that measures to this subcarrier is more steady, and mean square deviation is less.
Up channel describing message (UCD in present WiMAX system, Uplink Channel Descriptor) indicated the distribution thresholding of Band AMC in, portable terminal/contracting terminal (MS/SS, Mobile Station/Subscriber Station) determines whether to trigger the operation that enters Band AMC by the distribution thresholding of Band AMC.MS/SS utilizes and reports response message (REP-RSP, Report Response) (for SS is four to report 4 or 5, for MS is four or five) the best carrier band interference-to-noise ratio metrical information (CINR of frequency band (Band AMC), Carrier-To-Interference-And-Noise Rati) gives base station (BS, Base Station), purpose is to tell BS to wish to enter Band AMC zone.In beginning during the release Band AMC timer of UCD configuration from next frame, MS/SS uses channel quality information channel (CQICH always, Channel Quality Information Channel) reports difference CINR (DCINR, Differential CINR).The CQICH channel is to distribute to the subchannel that MS/SS distributes by BS after MS/SS networks, and the periodicity CINR measurement that the CQICH channel is used for MS reports.After at present BS receives the metrical information in the Band AMC zone that REP-RSP reports in the system, know that being intended that of MS/SS enters Band AMC zone, just handle whether can in the Band AMC zone that MS/SS reports, carry out regular traffic according to system's present case, do not enter Band AMC zone if BS side actual conditions do not satisfy this MS/SS, do not require BS to give the response of MS/SS echo reply at present in the agreement.In in these cases during the release Band AMC timer of UCD configuration, MS/SS takies always that CQICH reports DCINR and report configuration when not paying close attention to the CQICH channel allocation.In addition, DCINR is that the initial code (preamble) of 4 or 5 selecteed frequency bands reporting of its CQICH channel is gone up the differential measurement values of measuring (1 expression is increased, 0 expression reduces, step-length is 1 dB), the result that the CQICH channel reports uses 6 bit bit representations, not indicating reported result in these 6 bit positions is still effective CINR (ECINR, Eeffective CINR) of DCINR, physics CINR (PCINR, Physical CINR).
Therefore, even BS does not reply refuse information to MS when finding to satisfy user's request according to present system situation yet, MS/SS takies the CQICH channel at the AMC of UCD configuration always and reports DCINR in release time, take valuable CQICH channel resource.In addition, the next frame of MS/SS after sending REP-RSP uses the CQICH channel to report DCINR, but owing to do not indicate in 6 bit positions that report of CQICH is the CINR (DCINR, PCINR, ECINR) of which kind of type, the time can cause power control inaccurate when BS uses this to report CINR to carry out power control, make managing business seriously unreliable.
Summary of the invention
The embodiment of the invention provides a kind of band-adaptive encoded traffic processing method, equipment and system, can improve the service efficiency of CQICH channel and the accuracy of power control by this band-adaptive encoded traffic processing method, equipment and system.
