Detailed description of the invention

Currently for LTE protocol descending for, along with the application of increasing multi-antenna technology, Physical Downlink Shared Channel (PDSCH, Physical Downlink Shared Channel) becomes Become increasingly complex, it is desirable to community can the most online and transmission user also get more and more, and so makes Become PDSCH channel more and more higher to the requirement of the disposal ability of baseband board.

For LTE protocol is up, subscriber equipment (UE, User Equipment) is supported many Antenna transmission, multi-cell cooperating, intra-cell users on-line normalization also get more and more, and cause up Demodulate more and more higher for the requirement of the disposal ability of baseband board.

It is the implementation method of downgoing baseband resource pool in prior art LTE base station refering to Fig. 1, Fig. 1 Schematic diagram, downgoing baseband resource pool has two baseband boards: mainboard and from plate, and mainboard is redaction Baseband board, is the baseband board of early version from plate.The main control module of base station manages mainboard and from plate simultaneously, A part of downlink user is assigned to mainboard and processes by main control module, is distributed by another part downlink user Process to from plate.The process of whole downlink user is divided into bit-level and symbol level, from plate to descending use The data at family process the degree of bit-level and can terminate, and then the data of bit-level are transferred to main Plate, is completed the remaining process of all downlink users by mainboard.

In such scheme, mutual between master/slave board is the number processing bit-level degree of downlink user According to.In the data handling procedure of whole downlink user, if by whole down user data Processing operand and regard an entirety as, the operand that processes of bit-level only accounts for the 30% of whole operand, The operand of 70% is all that symbol level processes, so, can not be the most right from plate in existing scheme The process operand of the data of whole downlink user is shared.

It is uplink baseband resource in prior art LTE base station refering to Fig. 2 and Fig. 3, Fig. 2 and Fig. 3 The implementation method in pond, uplink baseband resource pool has two baseband boards: mainboard and from plate, and mainboard is new The baseband board of version, is the baseband board of early version from plate.Main control module is by the uplink user in community Information repeat to be allocated to mainboard and from plate；Or according to load balancing, user profile is joined respectively Put to mainboard with from plate；Mainboard L2 scheduler module is according to load balancing, by between current launch time Uplink user to be processed is needed to distribute to mainboard every (TTI, Transmission Time Interval) Process with from plate；Mainboard and from plate respectively to distribution uplink user physical uplink share letter Road (PUSCH, Physical Uplink Shared Channel), Physical Uplink Control Channel (PUCCH, Physical Uplink Control Channel) and measuring reference signals (SRS, Sounding Reference Signal) data that carried of channel process.

The implementation in above-mentioned ascending resource pond, has three problems: first, and multiple user's frequency domains provide The when of the multiplexing of source, between multiple users, there is public process part, assist between the most multiple users Deal with and also contribute to performance boost, if the plurality of user distributes on different boards, will cause Double counting, wastes hardware resource.Second, PUSCH channel consideration coordinate multipoint (COMP, Coordinated Multi-Point) cooperation scene time, if according to user do resource pool distribution, and In channel, two users are dispensed on different plates and process, and COMP data need to transmit many parts, The operation of interference mitigation (IC, Interference Canceling) is done also for COMP minizone Inconvenient.3rd, the L2 scheduler module centralized dispatching of mainboard can only be used, each baseband board is not Can independently dispatch, can not Parallel Scheduling, easily waste resource.

The present invention is described in detail with embodiment below in conjunction with the accompanying drawings.

It is the implementation method one of downgoing baseband resource pool in LTE base station of the present invention refering to Fig. 4, Fig. 4 The flow chart of embodiment, including:

Step S101: main control module is according to mainboard and the letter from the respectively the most configured downlink user of plate Breath, to mainboard and the channel from the plate corresponding downlink user of scheduling.

Main control module is to be controlled to mainboard with from plate in LTE base station downgoing baseband resource pool, adjust Degree, the module of configuration, such as: to mainboard and the information that is respectively configured downlink user from plate；To master Plate and the channel from plate dispatching downlink user respectively, process for mainboard with from plate；To mainboard and from Plate is respectively configured cell information；According to and the disposal ability of baseband board (mainboard or from plate), amendment Parameter of community etc..After increasing baseband board in LTE base station, main control module can identify newly automatically The baseband board increased and the disposal ability of this baseband board.

Mainboard and be the baseband board of LTE base station from plate, typically represents new baseband board and old base band Plate, mainboard and the quantity from plate are determined according to practical situations.

Downlink user refers to that base station sends the user of information to the subscriber equipment of user.Need explanation It is that downlink user herein can be the downlink user of same community, it is also possible to be different districts Downlink user.

Channel is the passage of information transmission, when i.e. information is transmitted a path of process.

The channel of downlink user includes but not limited to: Physical Downlink Shared Channel PDSCH, physics Down control channel PDCCH, Physical Broadcast Channel PBCH etc..

Main control module, according to the most identified mainboard with from plate, for mainboard and is respectively configured from plate in advance The information of downlink user.According to the information of the most configured downlink user, main control module is to mainboard With from plate dispatch corresponding downlink user channel, in order to mainboard and from plate to channel carrying number According to processing.

Step S102: mainboard and the channel institute from scheduled to the main control module respectively downlink user of plate The information of carrying carries out the process of bit-level and symbol level, it is thus achieved that time domain data that mainboard produces and from The time domain data that plate produces.

Bit-level process specifically include that the CRC of transmission block (Transport Block, TB) additional, Sub-block segmentation and CRC add, chnnel coding, rate-matched, code block cascade, control information Chnnel coding and rate-matched, business datum and control information multiplexing, channel interleaving and data ratio Special scrambling etc..

Symbol level processes the channel volume specifically included that in each code word transmitted on the physical channel Bit after Ma scrambles；Bit after scrambling is modulated, obtains complex modulation symbols； Obtained complex modulation symbols is mapped in one or more transport layer；Complex modulation to every layer Symbol carries out precoding；Complex modulation symbols on each antenna port is mapped to resource element (RE, Resource Element) on；Each antenna port produces the time-domain signal of plural number.

Time domain is the fundamental property of signal, can understand the mutual shadow between reaction signal and interconnection line Ring.The information that the channel of the downlink user that mainboard is scheduled to main control module is carried carries out bit-level Process with symbol level, it is thus achieved that the time domain data that mainboard produces；Scheduled to main control module from plate The information that the channel of downlink user is carried carries out the process of bit-level and symbol level, it is thus achieved that produce from plate Raw time domain data.

LTE base station of the present invention at downgoing baseband resource pool, according to downlink user respectively to mainboard and from Plate carries out configurating downlink user profile, mainboard and the channel from the plate downlink user to distributing to be compared The superfine process with symbol level, in this way, it is possible to Appropriate application mainboard and the process from plate Ability.

It is downgoing baseband resource pool in LTE base station of the present invention refering to Fig. 5 to Fig. 7, Fig. 5 to Fig. 7 The flow chart of implementation method three embodiment, including:

Step S201: main control module is respectively to mainboard and the information from plate configurating downlink user.

Main control module is according to the most identified mainboard with from plate, for mainboard be respectively configured descending from plate The information of user.

Main control module is to be controlled to mainboard with from plate in LTE base station downgoing baseband resource pool, adjust Degree, the module of configuration.

Step S202: main control module is according to mainboard and the letter from the respectively the most configured downlink user of plate Breath, to mainboard and the channel from the plate corresponding downlink user of scheduling.

According to the information of the most configured downlink user, main control module dispatches phase to mainboard with from plate Answer the channel of downlink user, in order to mainboard and from plate to channel carrying data process.

Main control module, can be according to two kinds to mainboard with when the channel of corresponding downlink user dispatched by plate Situation is respectively to mainboard and the channel from the plate corresponding downlink user of scheduling, respectively:

The first foundation: main control module distinguishes the most configured downlink user information according to mainboard with from plate And load balancing, to mainboard and the current Transmission Time Interval dispatching its loading condition corresponding from plate TTI needs the channel of downlink user to be processed.

Transmission Time Interval (TTI) is at UMTS (UMTS, Universal Mobile Telecommunications System) and other numeral telecommunication network (such as LTE system) In a parameter, refer to the length of in wireless link one independent decoding transmission.TTI with Relevant from the size of the data block of higher Internet to radio link layer.It is RRM The ultimate unit of (such as scheduling etc.) administered time.The corresponding business of each transmission channel, Owing to miscellaneous service is different to the requirement of time delay, so its TTI is different, TTI can be 10ms, 20ms, 40ms or 80ms etc..

Load balancing refers to that mainboard and the downlink user number loaded respectively from plate substantially equalize, such as, It is 10 that main control module is allocated to the downlink user number of mainboard load, is allocated to the descending use from plate load Amount is 5, and now, according to load balancing, main control module is to corresponding from plate load feelings from plate scheduling The current TTI of condition needs the channel of downlink user to be processed.

The second foundation: main control module is believed according to mainboard with from the downlink user that plate is the most configured Breath, and mainboard and the disposal ability from plate or the characteristic of support are corresponding with from plate scheduling to mainboard The channel of the downlink user of the characteristic of its disposal ability or support.

Mainboard and the disposal ability from plate, such as, the flow of mainboard is 500M, from the flow of plate For 300M, at this point it is possible to by downlink user to descending use less than 300M of the requirement of flow The channel dispatch at family is given and is processed from plate, by downlink user to the requirement of flow more than under 300M The channel dispatch of row user processes to mainboard.

Mainboard and the characteristic supported from plate, such as employ the characteristic that product is new in downlink user, from When plate cannot process, the channel of this downlink user can be dispatched to mainboard process to mainboard.

In actual applications, can consider mainboard and the disposal ability from plate and mainboard and from The characteristic that plate is supported, or only consider mainboard and the disposal ability from plate, or only consider mainboard and The characteristic supported from plate.

Main control module, can be according to reality to mainboard with when the channel of corresponding downlink user dispatched by plate Applicable cases selects two kinds of above-mentioned foundations.

Step S203: mainboard and the channel institute from scheduled to the main control module respectively downlink user of plate The information of carrying carries out the process of bit-level and symbol level, it is thus achieved that time domain data that mainboard produces and from The time domain data that plate produces.

Bit-level processes and specifically includes that the CRC of transmission block is additional, sub-block segmentation and CRC is additional, The cascade of chnnel coding, rate-matched, code block, the chnnel coding controlling information and rate-matched, industry Business data and control information multiplexing, channel interleaving and data bit scrambling etc..

Symbol level processes the channel volume specifically included that in each code word transmitted on the physical channel Bit after Ma scrambles；Bit after scrambling is modulated, obtains complex modulation symbols； Obtained complex modulation symbols is mapped in one or more transport layer；Complex modulation to every layer Symbol carries out precoding；Complex modulation symbols on each antenna port is mapped on resource element； Each antenna port produces the time-domain signal of plural number.

Step S203 specifically includes:

Step S203a: mainboard and the physics from scheduled to the main control module respectively downlink user of plate The information that DSCH Downlink Shared Channel PDSCH is carried carries out the process of bit-level and symbol level.

Or, step S203b: mainboard and from scheduled to the main control module respectively downlink user of plate Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel) is held The information carried carries out the process of bit-level and symbol level.

Step S204: the time domain data produced to mainboard transmission from plate from plate.

The information carried from the channel of the plate downlink user scheduled to main control module carries out bit Level and the process of symbol level, it is thus achieved that the time domain data produced from plate.The time domain data that will produce from plate It is transferred to mainboard.

Step S205: the time domain data that mainboard produces since time domain data and this plate of plate in the future is carried out Superposition.

Step S206: the time domain data after superposition is sent by mainboard to middle radio-frequency module.

Step S207: mainboard downlink user allocated to main control module control format instruction CFI, Hybrid automatic repeat-request instruction HI, Physical Broadcast Channel PBCH, synchronous channel SCH, location The information that-pilot tone P-RS and channel condition information-pilot tone CSI-RS common signal channel are carried is carried out Process.

Step S207 performed before step S206.

In a word, LTE base station of the present invention is at downgoing baseband resource pool, according to downlink user respectively to master Plate and carry out configurating downlink user profile from plate, mainboard and from the plate channel to the downlink user of distribution Carry out the process of bit-level and symbol level, in this way, it is possible to Appropriate application mainboard and from plate Disposal ability.
