Main baseband processing chip can carry out Interference Cancellation (IC with passing through decoding back gained data; Interference Cancellation); Perhaps; To pass through decoding back gained data and be sent to all said prothetic group tape handling chips, whether carry out the processing of IC by its decision to offer all prothetic group tape handling chips.In embodiments of the present invention, Interference Cancellation is meant the signal (data) after demodulation or the decoding is carried out reconstruct, the signal after the reconstruct (data) balanced out from antenna data, to reduce the interference of this user to other user.Need to prove, be not all can carry out Interference Cancellation to all users, whether carries out Interference Cancellation for certain user and determined by resource management module, and for example, this user is the highest user of speed in main baseband processing chip, then carries out Interference Cancellation.Yet, in prothetic group tape handling chip, if this user rate is not the highest, and than the CU of this user's higher rate all Interference Cancellation resources, this user can not carry out Interference Cancellation in prothetic group tape handling chip.

Carry out between main baseband processing chip and the prothetic group tape handling chip can carrying out message informing earlier before the data interaction, making can proper communication between winner's baseband processing chip and the prothetic group tape handling chip.Particularly; As radio network controller (RNC; Radio Network Controller) designated user equipment (is promptly sent the subscriber equipment of upstream data simultaneously to main baseband processing chip and prothetic group tape handling chip; Down with) when carrying out operation such as RL foundation, reprovision and deletion, RNC notice main control module is operated accordingly, promptly; When RNC operated specifying UE to carry out RL foundation, reprovision and deletion etc., this RNC of RNC notice main control module carried out operations such as RL foundation, reprovision and deletion to designated user equipment.After main control module is received this notice, transmit to main baseband processing chip, main baseband processing chip receives the RNC that is transmitted by main control module designated user equipment is carried out the notice that RL foundation, reprovision and deletion etc. are operated.In embodiments of the present invention, main control module can be a logical concept, and for example, main control module can be a physical entity, also can be that a plurality of physical entities are mapped in different physics NodeB, RNC etc.RNC can be explicit signaling to the advice method of main control module; Also can be the notice of implicit expression, for example, for this advice method of explicit signaling; All signalings are resolved signaling by main control module after being sent to main control module; Be distributed to main baseband processing chip and prothetic group tape handling chip, and the advice method of implicit expression can be directly signaling to be passed to main baseband processing chip or prothetic group tape handling chip; Resolve signaling by main baseband processing chip or prothetic group tape handling chip, the signaling main control module after main then baseband processing chip or prothetic group tape handling chip will be resolved; Main control module also can be notified the address information of the corresponding main baseband processing chip of all or part master baseband processing chip/prothetic group tape handling chip/prothetic group tape handling chip as required, and main baseband processing chip/prothetic group tape handling chip receives by the main baseband processing chip of main control module notice or the address information of prothetic group tape handling chip.For example, when main baseband processing chip changes, notify all prothetic group tape handling chips, when prothetic group tape handling chip changes, notify main baseband processing chip, the notice here is not limited to aforesaid way, also can adopt modes such as broadcasting, multicast.

Can know from the invention described above embodiment; Because carrying out high specific, the upstream data that main baseband processing chip was sent to said main baseband processing chip to subscriber equipment before this merges; Then, the upstream data that these high specific merging gained data are received said at least one prothetic group tape handling chip with at least one prothetic group tape handling chip carries out high specific merging gained data, carries out high specific once more and merges; Therefore; Selectivity during with respect to soft handover merges, and the method that the embodiment of the invention provides can obtain good gain, improves the data demodulates performance; On the other hand; Main baseband processing chip receives prothetic group tape handling chip upstream data is carried out the data after high specific merges; Thisly can obtain softer merging gain, reduce user's number of retransmissions, promote the speed of Cell Edge User through alternant way between sheet; Reduce cutting off rate, promote user experience.

See also accompanying drawing 2, the acquisition that another embodiment of the present invention provides merges the method flow sketch map of gain, mainly comprises step:

S201, main baseband processing chip is deciphered upstream data.

Decoding (or decoding) is the inverse process of coding, and purpose is the upstream data before reduction or the acquisition coding.In embodiments of the present invention; Said upstream data is the data of being sent to prothetic group tape handling chip and said main baseband processing chip simultaneously by subscriber equipment; And main baseband processing chip, prothetic group tape handling chip respectively with accompanying drawing 1 said embodiment in main baseband processing chip, prothetic group tape handling chip similar; Do not do here and give unnecessary details, can consult previous embodiment.

S202; If the upstream data decoding error that main baseband processing chip decoding error and all prothetic group tape handling chips receive said prothetic group tape handling chip, the upstream data that then said main at least one prothetic group tape handling chip of baseband processing chip reception receives said at least one prothetic group tape handling chip carries out the data after high specific merges.

Obviously, it is nonsensical to carry out the high specific merging for the data of decoding error, and as previously mentioned, decoding can have been carried out high specific merging (no matter being to carry out the high specific merging for the first time or carry out the high specific merging once more) in data and carry out afterwards.Therefore; In the present embodiment; If the upstream data decoding error that main baseband processing chip decoding error and all prothetic group tape handling chips receive said prothetic group tape handling chip; Then said main baseband processing chip receives the upstream data that at least one prothetic group tape handling chip receives said at least one prothetic group tape handling chip and carries out the data after high specific merges, so that in processing such as carried out that high specific is deciphered after merging again.

S203, the data that main baseband processing chip receives said main baseband processing chip are carried out high specific and are merged.

In the present embodiment; If main baseband processing chip is correct to the upstream data decoding of its reception; Then main baseband processing chip can carry out high specific to said decoding proper data and merge; Perhaps; If have at least a prothetic group tape handling chip correct in all prothetic group tape handling chips to the upstream data decoding of its reception; Then main baseband processing chip can receive at least one prothetic group tape handling chip upstream data is carried out the data behind the correct decoding, that is, receive come from one of them prothetic group tape handling chip to the upstream data of its reception carry out behind the correct decoding data, come from all prothetic group tape handling chips the upstream data of its reception carried out the data behind the correct decoding; Perhaps according to preset condition, the upstream data that selective reception part prothetic group tape handling chip receives this part prothetic group tape handling chip carries out the data behind the correct decoding.Particularly, these data can be soft bit/hard bits that soft symbol obtains after constellation diagram mapping and decoding, wherein; Soft symbol is meant a symbol before constellation diagram mapping, possibly comprise a bit, also possibly comprise a plurality of bits; The bit number that specifically comprises is relevant with modulation system, and for example, the symbol of BPSK modulation system comprises 1 bit; The sign bit of QPSK modulation system comprises 2, and the symbol of 16QAM modulation system comprises 3 bits, or the like.

If the upstream data decoding error that said main baseband processing chip decoding error and all said prothetic group tape handling chips receive said prothetic group tape handling chip, then main baseband processing chip carry out the high specific merging to the data that receive and comprise:

Main baseband processing chip carries out high specific to the upstream data (subscriber equipment is sent to the upstream data of said main baseband processing chip) that receives before the decoding error and merges.Because subscriber equipment sends upstream data to main baseband processing chip and all prothetic group tape handling chips simultaneously, prothetic group tape handling chip can carry out the upstream data that prothetic group tape handling chip receives before decoding error being sent to main baseband processing chip after high specific merges.After main baseband processing chip receives this part data; Data to carry out the high specific merging to the upstream data that the data of this main baseband processing chip after the upstream data of reception before the decoding error carries out the high specific merging and at least one prothetic group tape handling chip receive before decoding error after are carried out high specific once more and are merged; Afterwards, main baseband processing chip carries out once more that high specific merges that back gained data are deciphered and processing such as judgement to said.

Main baseband processing chip can carry out Interference Cancellation with passing through decoding back gained data; Perhaps; To pass through decoding back gained data and be sent to all said prothetic group tape handling chips, whether carry out the processing of Interference Cancellation by its decision to offer all prothetic group tape handling chips.In embodiments of the present invention, Interference Cancellation is meant the signal (data) after demodulation or the decoding is carried out reconstruct, the signal after the reconstruct (data) balanced out from antenna data, to reduce the interference of this user to other user.Need to prove, be not all can carry out Interference Cancellation to all users, whether carries out Interference Cancellation for certain user and determined by resource management module, and for example, this user is the highest user of speed in main baseband processing chip, then carries out Interference Cancellation.Yet, in prothetic group tape handling chip, if this user rate is not the highest, and than the CU of this user's higher rate all used resources of Interference Cancellation, this user can not carry out Interference Cancellation in prothetic group tape handling chip.

Similar with previous embodiment, carry out between main baseband processing chip and the prothetic group tape handling chip can carrying out message informing earlier before the data interaction, making can proper communication between winner's baseband processing chip and the prothetic group tape handling chip.Particularly; As radio network controller (RNC; When Radio Network Controller) designated user equipment being carried out operation such as RL foundation, reprovision and deletion, RNC notice main control module is operated accordingly, promptly; When RNC carried out operation such as RL foundation, reprovision and deletion to designated user equipment, this RNC of RNC notice main control module carried out operations such as RL foundation, reprovision and deletion to designated user equipment.After main control module is received this notice, transmit to main baseband processing chip, main baseband processing chip receives the RNC that is transmitted by main control module designated user equipment is carried out the notice that RL foundation, reprovision and deletion etc. are operated.In embodiments of the present invention, main control module can be a logical concept, and for example, main control module can be a physical entity, also can be that a plurality of physical entities are mapped in different physics NodeB, RNC etc.RNC can be explicit signaling to the advice method of main control module; Also can be the notice of implicit expression, for example, for this advice method of explicit signaling; All signalings are resolved signaling by main control module after being sent to main control module; Be distributed to main baseband processing chip and prothetic group tape handling chip, and the advice method of implicit expression can be directly signaling to be passed to main baseband processing chip or prothetic group tape handling chip; Resolve signaling by main baseband processing chip or prothetic group tape handling chip, the signaling main control module after main then baseband processing chip or prothetic group tape handling chip will be resolved; Main control module also can be notified the address information of the corresponding main baseband processing chip of all or part master baseband processing chip/prothetic group tape handling chip/prothetic group tape handling chip as required, and main baseband processing chip/prothetic group tape handling chip receives by the main baseband processing chip of main control module notice or the address information of prothetic group tape handling chip.For example, when main baseband processing chip changes, notify all prothetic group tape handling chips, when prothetic group tape handling chip changes, notify main baseband processing chip, the notice here is not limited to aforesaid way, also can adopt modes such as broadcasting, multicast.

Can know from the invention described above embodiment; Because main baseband processing chip was deciphered the upstream data that subscriber equipment is sent to said main baseband processing chip before this; When the upstream data decoding error that main baseband processing chip decoding error and all prothetic group tape handling chips receive said prothetic group tape handling chip; The upstream data that main baseband processing chip is sent to said main baseband processing chip to subscriber equipment carries out high specific and merges upstream data that back gained data receive said at least one prothetic group tape handling chip with at least one prothetic group tape handling chip and carry out high specific and merge the gained data; Carry out high specific once more and merge, therefore, the selectivity during with respect to soft handover merges; The method that the embodiment of the invention provides can obtain good gain, improves the data demodulates performance; On the other hand; Main baseband processing chip receives prothetic group tape handling chip upstream data is carried out the data after high specific merges; Thisly can obtain softer merging gain, reduce user's number of retransmissions, promote the speed of Cell Edge User through alternant way between sheet; Reduce cutting off rate, promote user experience.
