Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not paying the every other embodiment that obtains under the creative work prerequisite.
The transmission method flow chart of the business datum that Fig. 1 provides for the embodiment of the invention.The present embodiment is from the technical scheme of the transmission method of network side explanation business datum of the present invention.As shown in Figure 1, the transmission method of the present embodiment business datum comprises:
The business datum of same business may have been supported plurality of data transmission modes, and the effect that the business datum of employing different mode transmission reaches may be different.For example, data-transmission mode can comprise: CoMP and non-CoMP pattern etc., and when adopting CoMP mode transfer business datum, the availability gain, but the time delay of transfer of data is longer; When adopting non-CoMP mode transfer business datum, the time delay less of transfer of data, but for cell edge, the poor-performing of the aspects such as user throughput and power gain.
For a certain Cell Edge User, the required business of Cell Edge User has polytype, before network side sends business datum to Cell Edge User, can be according to the type of business, determine targetedly this professional data-transmission mode, so that this Cell Edge User can adopt one or more data-transmission modes, transmit the business datum of self required multiple business type, thereby be conducive to ensure the service quality of the required business of Cell Edge User.
This professional data-transmission mode that step 12, notifying cell edge customer are determined, and according to this professional data-transmission mode of determining, carry out this professional business data transmission with this Cell Edge User.
If determine that professional data-transmission mode is the CoMP pattern, the Serving cell of Cell Edge User need to be failed this professional business datum to Cell Edge User with keeping pouring in jointly with cooperation cell, thereby strengthens this professional signal; If determine that professional data pattern is non-CoMP pattern, the Serving cell of Cell Edge User adopts the business datum that traditional unicast mode transfer should business.
In this step, the data-transmission mode of the above-mentioned business that network side send to be determined to Cell Edge User can be used for this Cell Edge User and determines the corresponding HARQ configuration parameter of data-transmission mode with above-mentioned business.
The HARQ configuration parameter that different data-transmission modes is corresponding can be different.Concrete, the HARQ configuration parameter can comprise Transmission Time Interval (Transmission Time Interval is called for short TTI) parameter, the TTI parameter that different data-transmission modes is corresponding is different.For example: under the situation that Serving cell and the cooperation cell of Cell Edge User belongs to different base station, because the extra time delay that the CoMP pattern is introduced is longer, the TTI value of CoMP mode transfer is greater than the TTI value of non-CoMP mode transfer.After network side has been determined professional data-transmission mode, this professional data-transmission mode that network side will be determined is notified to Cell Edge User, so that Cell Edge User is when the data receiver failure, adopt pre-TTI parameter corresponding to this data-transmission mode, send HARQ to network side, be used for the corresponding business datum of request retransmission.
The inventor finds in realizing embodiment of the invention process, and prior art can be according to different Cell Edge User specified data transmission modes.But for a certain Cell Edge User, as long as this Cell Edge User and network side consult data-transmission mode, required all the professional business datums of this Cell Edge User all must be through consultation good data-transmission mode, transmitting user data, be in the prior art, for same Cell Edge User, no matter how the required type of service of this Cell Edge User is enriched, network side can only adopt a kind of data-transmission mode that consults with this Cell Edge User, various types of business datums that transmission user is required.This is so that the flexibility of the business data transmission of Cell Edge User is relatively poor, if include the business that some property requires in the required type of service of this Cell Edge User, professional such as delay sensitive, single data-transmission mode possibly can't satisfy these professional service quality.
Illustrate, the CoMP pattern has also been introduced extra time delay to transfer of data when increasing the power gain that receives signal.In a single day Cell Edge User and network side consult when adopting the CoMP mode transfer, and all business that this Cell Edge User is required all must adopt the CoMP mode transfer.If the Serving cell of Cell Edge User and cooperation cell belong under the situation of different base station, owing to need to carry out handling through consultation of data interaction between the different base station, so the extra time delay that the CoMP mode transfer is introduced is longer.If the required business of Cell Edge User this moment is that voice are (such as internet protocol voice service (VoiceOver Internet Protocol, abbreviation VoIP)) delay sensitive such as business, game on line (Gaming) business is professional, also adopt the CoMP pattern to transmit, the extra time delay of introducing in the CoMP mode transfer process will weaken the continuity of delay sensitive business data transmission, thereby have a strong impact on the service quality (QoS) of delay sensitive business.
In the transmission method of the present embodiment business datum, type to the required business of a certain Cell Edge User is distinguished, can be according to the type of service of concrete business, determine targetedly corresponding data-transmission mode, and notify each professional established data transmission mode to this Cell Edge User, so that network side and this Cell Edge User all can be according to the related datas of established data transmission mode transport service.Therefore, for same Cell Edge User, the transmission method of the present embodiment business datum is that this Cell Edge User transmits dissimilar business datum by plurality of data transmission modes, and the technical foundation that realizes is provided.For same Cell Edge User, transmit the prior art of various types of business datums by a kind of data-transmission mode, the present embodiment has improved the flexibility of the business data transmission of Cell Edge User, thereby is conducive to ensure the service quality of the required business of Cell Edge User.
The transmission method flow chart of the another kind of business datum that Fig. 2 provides for the embodiment of the invention.The present embodiment is from the technical scheme of the transmission method of user's side explanation business datum of the present invention.As shown in Figure 2, the transmission method of the present embodiment business datum comprises:
Network side is determined the data-transmission mode that this is professional according to the type of the required business of Cell Edge User, and after determining this professional data-transmission mode, network side can send to Cell Edge User with this professional data-transmission mode information of determining.
In subscriber equipment and network side communication process, subscriber equipment can according to the corresponding relation of pre-configured data-transmission mode and HARQ configuration parameter, be determined the HARQ configuration parameter that this professional data-transmission mode is corresponding.Take defeat in this professional business datum, the HARQ configuration parameter corresponding according to this professional data-transmission mode, send this professional HARQ, be used for the request network side and retransmit this professional business datum.
The HARQ configuration parameter that different data-transmission modes is corresponding can be different.The corresponding relation of Cell Edge User pre-configured data-transmission mode and HARQ configuration parameter on subscriber equipment.Concrete, data-transmission mode can comprise: CoMP pattern and non-CoMP pattern.The corresponding HARQ configuration parameter of CoMP pattern, corresponding the 2nd HARQ configuration parameter of non-CoMP pattern.
If Cell Edge User receives business datum failure and data-transmission mode that should business when being the CoMP pattern, can send this professional HARQ according to a described HARQ configuration parameter, be used for the business datum that the request network side retransmits described business.Perhaps, if Cell Edge User receives business datum failure and data-transmission mode that should business when being non-CoMP pattern, can send this professional HARQ according to described the 2nd HARQ configuration parameter, be used for the request network side and retransmit this professional business datum.
For example: the HARQ configuration parameter can comprise the TTI parameter, and the TTI parameter that different data-transmission modes is corresponding is different.Under the situation that Serving cell and the cooperation cell of Cell Edge User belongs to different base station, because the extra time delay that the CoMP pattern is introduced is longer, the TTI value of CoMP mode transfer is greater than the TTI value of non-CoMP mode transfer.After network side has been determined professional data-transmission mode, this professional data-transmission mode that network side will be determined is notified to Cell Edge User, so that Cell Edge User is when the data receiver failure, adopt pre-TTI parameter corresponding to this data-transmission mode, send HARQ to network side, be used for the corresponding business datum of request retransmission.
The transmission method of the present embodiment business datum is distinguished the type of the required business of Cell Edge User by network side, according to the type of service of concrete business, determines targetedly corresponding data-transmission mode.Therefore, the transmission method of the present embodiment business datum is that same Cell Edge User transmits dissimilar business datum by plurality of data transmission modes, and the technical foundation that realizes is provided.For same Cell Edge User, transmit the prior art of various types of business datums by a kind of data-transmission mode, the present embodiment has improved the flexibility of the business data transmission of Cell Edge User, thereby is conducive to ensure the service quality of the required business of Cell Edge User.
The transmission method flow chart of the another kind of business datum that Fig. 3 provides for the embodiment of the invention.In the present embodiment, Cell Edge User access residential quarter is Serving cell; Adjacent with Serving cell and with Cell Edge User relevant residential quarter is cooperation cell.The present embodiment hypothesis: Serving cell, cooperation cell, Cell Edge User are all supported CoMP pattern and two kinds of data-transmission modes of non-CoMP pattern.As shown in Figure 3, the transmission method of the present embodiment business datum comprises:
The Serving cell of step 31, Cell Edge User obtains the type of the required business of Cell Edge User, judges whether the required business of Cell Edge User is that non-delay sensitive is professional, if so, and execution in step 33; Otherwise, execution in step 32.
The type of the required business of Cell Edge User can comprise: the professional and non-delay sensitive of delay sensitive is professional.The delay sensitive business can comprise: VOIP is professional, game on line is professional, streaming media service, video traffic, visual telephone service, IPTV (Internet Protocol Television, abbreviation IPTV) business, circuit switching (Circuit Switch is called for short CS) business and other delay sensitive business etc.; Non-delay sensitive business can comprise: follow file transfer protocol (FTP) (File Transportation Protocol, be called for short FTP) business, professional, Email (email) business of business, web browsing business, short message service, MMS, online chatting of following HTML (Hypertext Markup Language) (Hyper Text Transfer Protocol is called for short HTTP) and other are to the insensitive business of time delay etc.
Serving cell can be reported according to the power measurement that Cell Edge User reports, and determines the information of the cooperation cell of Cell Edge User, and afterwards, the information of the cooperation cell that the Serving cell basis is obtained judges whether whether self belong to same base station with cooperation cell.
If it is professional that the required business of Cell Edge User is non-delay sensitive, then no matter whether Serving cell and the cooperation cell of Cell Edge User belong to same base station, Serving cell can determine that the data-transmission mode of the business that this Cell Edge User is required is the CoMP mode transfer, to improve user throughput and the signal power gain of cell edge.
If to be delay sensitive professional and Serving cell and cooperation cell belong to same base station for the required business of Cell Edge User, Serving cell can determine that also the data-transmission mode of the business that this Cell Edge User is required is the CoMP mode transfer, to improve user throughput and the signal power gain of cell edge.
Serving cell at first generates the business data packet with the CoMP mode transfer, and sends this business data packet to cooperation cell when determine adopting the business datum that the CoMP mode transfer should business.Afterwards, Serving cell and cooperation cell cooperation are failed this professional business data packet to Cell Edge User with keeping pouring in jointly.For Cell Edge User, its signal power strength that receives business data packet significantly strengthens.
When Serving cell generates the business data packet of the business that adopts the CoMP mode transfer, need to carry out the interlayer notice according to this professional data-transmission mode.For example: Serving cell can comprise three layers of processing to the encapsulation process process of business datum usually: Radio Resource control (Radio Resource Control, abbreviation RRC) layer, media access control (Media Access Control is called for short MAC) layer and physical layer.
Rrc layer is used for the type according to business, determines professional data-transmission mode, and according to corresponding data-transmission mode scheduling resource.Concrete, when rrc layer is determined the data-transmission mode of this service needed employing, need what the data-transmission mode that notice MAC layer should business is, concrete advice method is unrestricted, for example: rrc layer can the new field of the newly-increased signaling that sends to the MAC layer or original signaling or in, carry for the identification information of the logic channel that transmits this professional business datum and the corresponding relation of data-transmission mode, be used for notifying the business datum of logic channel carrying corresponding to which sign to adopt the CoMP mode transfer, the business datum of the logic channel carrying which sign is corresponding adopts non-CoMP mode transfer; Perhaps, rrc layer also can send in the business datum to MAC, increases a bit (Bit) position newly, is used to indicate the data-transmission mode of the current business datum that issues.
When the MAC layer knows that needs adopt CoMP mode transfer business datum, increase the address information of cooperation cell in the packet header of this business datum, and send this business datum by transport layer to corresponding cooperation cell.When the MAC layer is known the non-CoMP mode transfer business datum of employing, then need to not increase in the packet header of this business datum the address information of cooperation cell, namely transport layer does not need to send this business datum to corresponding cooperation cell.
Because delay sensitive business self having relatively high expectations to delay performance, if adopt the business datum of CoMP mode transfer delay sensitive business, the extra time delay that CoMP mode transfer process between the base station is introduced is longer, this part time delay will weaken the continuity of delay sensitive business data transmission, thereby have a strong impact on the service quality of delay sensitive business.Therefore, the data-transmission mode of delay sensitive business is not suitable for the CoMP mode transfer between the base station.
Concrete, if to be delay sensitive professional and Serving cell and cooperation cell belong to different base station for the required business of Cell Edge User, Serving cell determines that the data-transmission mode of the business that this Cell Edge User is required is non-CoMP mode transfer, with the service quality of the delay sensitive business that improves Cell Edge User.
In this step, the concrete advice method of professional data-transmission mode information is unrestricted.Optionally, Serving cell one of can be in the following ways, and the notifying cell edge customer sends this professional data-transmission mode information:
(1) transmission the first indication information in Physical Downlink Control Channel (Physical Downlink Control Channel is called for short PDCCH), it is the CoMP pattern that this first indication information is used to indicate this professional data-transmission mode.
For example: Serving cell can some field in the control information of PDCCH transmission increase a bit (bit) position, adopts the assignment of this bit position, indicates whether the data-transmission mode of current business is the CoMP pattern.Cell Edge User can be in the corresponding bits position of the respective field of PDCCH control information transmission, and the data-transmission mode of determining current business is CoMP pattern or non-CoMP pattern.
(2) adopt default special-purpose scrambler that scrambling is carried out in the control information of PDCCH transmission and process, the data-transmission mode that is used to indicate described business is the CoMP pattern.
For example: Serving cell and Cell Edge User can be consulted the special-purpose scrambler corresponding with the CoPM pattern in advance.When Serving cell is determined to adopt the CoMP mode transfer, adopt special-purpose wireless network temporary identity (Radio Network Temporary Identity is called for short RNTI) information, scrambling is carried out in the control information of PDCCH transmission processed.If the control information that Cell Edge User receives by PDCCH can adopt the RNTI information of consulting in advance to carry out descrambling, determine that then the data-transmission mode of current business is the CoMP pattern; Otherwise the data-transmission mode of current business is non-CoMP pattern.
(3) that the scheduling of resource pattern information of transmitting among the PDCCH is set to is semi-continuous (Semi-Persistent Scheduling is called for short SPS) scheduling method, being used to indicate professional data-transmission mode is non-CoMP pattern.
For example: Serving cell and Cell Edge User can be consulted in advance, adopt SPS scheduling method scheduling delay sensitive professional; Adopt non-SPS scheduling method to dispatch non-delay sensitive professional.Therefore, if in the control information of Serving cell by the PDCCH transmission, scheduling method is set to the SPS pattern, the data-transmission mode that current business then is described is non-CoMP pattern; Otherwise the data-transmission mode of current business is the CoMP pattern.
(4) at physical down Traffic Channel (Physical Downlink Service Channel, be called for short PDSCH) middle transmission the second indication information, it is the CoMP pattern that this second indication information is used to indicate professional data-transmission mode, and the identification information that needs the HARQ process of combined decoding.
For example: when Serving cell generates the rrc layer signaling, can at rrc layer signaling new field, be used for the ID that expression needs the HARQ process of combined decoding.Afterwards, need the id information of the HARQ of combined decoding process to send to Cell Edge User with including.Cell Edge User determines that this professional data-transmission mode is the CoMP pattern when receiving the business datum of HARQ process corresponding to these ID, and the business datum that the HARQ process that these ID are corresponding receives is carried out combined decoding.
The HARQ configuration parameter that different data-transmission modes is corresponding may be different.The corresponding relation of Cell Edge User pre-configured data-transmission mode and HARQ configuration parameter on subscriber equipment.Concrete, data-transmission mode can comprise: CoMP pattern and non-CoMP pattern.The corresponding HARQ configuration parameter of CoMP pattern, corresponding the 2nd HARQ configuration parameter of non-CoMP pattern.Cell Edge User is determined HARQ configuration parameter correspondingly according to the data-transmission mode of current business.
If Cell Edge User receives business datum failure and data-transmission mode that should business when being the CoMP pattern, can send this professional HARQ according to a described HARQ configuration parameter, be used for the business datum that the request network side retransmits described business.
If Cell Edge User receives business datum failure and data-transmission mode that should business when being non-CoMP pattern, can send this professional HARQ according to described the 2nd HARQ configuration parameter, be used for the request network side and retransmit this professional business datum.
The transmission method of the present embodiment business datum, the type of service required according to Cell Edge User, and the Serving cell of Cell Edge User and the attaching relation between the cooperation cell are determined professional data transmission targetedly.Concrete, if it is professional that the required business of Cell Edge User is non-delay sensitive, then no matter whether Serving cell and the cooperation cell of this Cell Edge User belong to same base station, all can adopt the business datum of the non-delay sensitive business of CoMP mode transfer, with user's throughput of raising cell edge and the power gain of signal.If it is professional that the required business of Cell Edge User is delay sensitive, and the Serving cell of this Cell Edge User and cooperation cell belong to same base station, can adopt the business datum of CoMP mode transfer delay sensitive business; Because the time delay that the CoMP transmission is introduced in the base station is less, this part time delay is less to the quality of service impacts of delay sensitive business, and namely Cell Edge User also can obtain the preferably service quality of delay sensitive business when obtaining power gain.If it is professional that the required business of Cell Edge User is delay sensitive, and the Serving cell of this Cell Edge User and cooperation cell belong to different base station, can adopt the business datum of non-CoMP mode transfer delay sensitive business; Because the time delay that the CoMP transmission is introduced between the base station is larger, this part time delay is larger to the quality of service impacts of delay sensitive business, therefore, be that Cell Edge User obtains the preferably service quality of delay sensitive business in order to ensure, this situation adopts the business datum of non-CoMP mode transfer delay sensitive business.As seen, the transmission method of the present embodiment business datum is that same Cell Edge User is by the dissimilar business datum of plurality of data transmission modes transmission, the technical foundation that realizes is provided, thereby improved the flexibility of Cell Edge User business data transmission, be conducive to ensure the Cell Edge User of supporting the CoMP mode transfer, obtain the service quality of delay sensitive business.
