Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearlyChu, intactly description, obviously, described embodiment is only the present invention's part embodiment, instead ofWhole embodiment. Based on the embodiment in the present invention, those of ordinary skill in the art are not making creationThe every other embodiment obtaining under property work prerequisite, belongs to the scope of protection of the invention.

Please refer to Fig. 1, is that the flow process of the first embodiment of the sending method of the measurement data of the embodiment of the present invention is shownIntention, described method comprises:

Step S11, the instruction of received beam shaping promoter's feedback measurement data.

Wherein, the instruction of the beam forming promoter's of reception feedback measurement data can be that beam forming is initiatedThe BeamformingReportPoll (beam forming report poll frame) that person sends.

Step S12, to beam forming promoter feedback packet containing part measurement data or do not comprise the number of measurement dataAccording to bag, and carry feedback packet containing part measurement data or do not comprise the packet of measurement data at this packetReason.

Wherein, described reason can comprise: there is no measurement data, or, though there is measurement data wave beam to becomeShape promoter's TXOP remaining time deficiency so that beam forming recipient feeds back whole measurement data.

Be understandable that, when step S11 receives the instruction of beam forming promoter's feedback measurement dataAfterwards, detect measurement data, if measurement data cannot be detected, step S12 can not become to wave beamShape promoter feeds back any measurement data; If the measurement data of detecting, calculates to wave beam furtherShape promoter feeds back whether surplus lower than beam forming promoter's TXOP of required time of whole measurement dataThe remaining time; If so, feed back whole measurement data to beam forming promoter; If not, stepS12 is to beam forming promoter feedback fraction or do not feed back measurement data, it should be noted that, if feedback sectionPoint measurement data, feeds back so the required time of this part measurement data and should be less than or equal to beam forming and initiateThe remaining time of person's TXOP.

The present embodiment, in the time receiving beam forming promoter's the instruction of feedback measurement data, forms to wave beamPromoter's feedback packet contains part measurement data or does not comprise the packet of measurement data, anti-to increase measurement dataThe flexibility of feedback mode, avoids the limitation of the existing middle mode that requires the whole measurement data of disposable feedback;Meanwhile, also carry at the packet of feedback the data that feedback packet contains part measurement data or do not comprise measurement dataThe reason of bag, does not have the whole measurement of disposable feedback clearly what to be designated as to beam forming promoterData, avoid the generation without instruction or wrong instruction situation, are conducive to beam forming promoter's subsequent operation.

Please refer to Fig. 2, is that the flow process of the second embodiment of the sending method of the measurement data of the embodiment of the present invention is shownIntention, Fig. 2 is that the reason that feedback packet contains part measurement data or do not comprise the packet of measurement data is not haveWhen measurement data, to the concrete refinement of Fig. 1, comprising:

Step S21, the instruction of received beam shaping promoter's feedback measurement data.

Step S22, feeds back the packet that does not comprise measurement data to beam forming promoter, and at this packetCarry the instruction without measurement data of reason and this packet.

Wherein, the reason of carrying is there is no measurement data, causes not having the factor of measurement data a lot, such asThere is no correct received beam shaping promoter's NDPA frame and NDP frame, thereby do not exist NDP frameMeasure, naturally there is no measurement data.

Particularly, the packet of step S22 feedback can be that VHTCompressedBeamforming is (superHigh-throughput beam forming compressed package), because step S22 does not feed back any measurement number to beam forming promoterAccording to, therefore in VHTCompressedBeamforming, do not comprise: for carrying measurement dataCompressedBeamformingReportfield (compressional wave beam shaping report territory).

Further, VHTCompressedBeamforming can comprise: VTHMIMOControlField, and in VTHMIMOControlfield, carry reason and VHTCompressedBeamformingDo not comprise the instruction of measurement data.

Particularly, please refer to table three, the value of residue burst field is set to " 111 " and the first burst fieldValue be set to " 0 ", to indicate the VHTCompressedBeamforming to beam forming recipient feedbackWithout measurement data; Reserved field is used to indicate to reason, and the value of for example reserved field is set to " 00 ", withInstruction does not have measurement data; It should be noted that, although feed back to beam forming promoter in the prior artWhile not comprising the VHTCompressedBeamforming of measurement data, the value of reserved field is also set to" 00 ", but in prior art, the setting " 00 " to reserved field of this kind of situation does not have concrete implication.

Table three

The present embodiment because there is no measurement data, does not therefore carry Compressed due to former in the packet of feedbackBeamformingReportfield, realizes and does not feed back any measurement data to beam forming promoter; In addition,In the packet of feedback, carry VHTMIMOControlfield, and at VHTMIMOControlfieldIn carry the packet of reason and feedback without the instruction of measurement data, make the ripple shaping promoter can be clearlyWhy solution does not feed back whole measurement data, thereby takes corresponding treatment measures, such as instruction wave beam becomesShape recipient remeasures rear feedback measurement data.
