Embodiment

At present, descending for the LTE agreement, application along with increasing multi-antenna technology, Physical Downlink Shared Channel (PDSCH, Physical Downlink Shared Channel) becoming becomes increasingly complex, require the sub-district user online simultaneously and transmission also to get more and more, caused the PDSCH channel more and more higher like this requirement of the disposal ability of baseband board.

Up for the LTE agreement, subscriber equipment (UE, User Equipment) supports in many antenna transmission, multi-cell cooperating, the sub-district the online transmission of user also more and more etc., causes uplink demodulation also more and more higher for the requirement of the disposal ability of baseband board.

Consult Fig. 1, Fig. 1 is the implementation method schematic diagram of downgoing baseband resource pool in the prior art LTE base station, and the downgoing baseband resource pool has two baseband boards: mainboard and slave plate, mainboard are the baseband board of redaction, and slave plate is the baseband board of early version.The main control module of base station is managed mainboard and slave plate simultaneously, and main control module is assigned to mainboard with a part of downlink user and handles, and another part downlink user is assigned to slave plate handles.The processing of whole downlink user is divided into bit-level and symbol level, and slave plate can finish the data processing of the downlink user degree to bit-level, gives mainboard with the transfer of data of bit-level then, is finished the remainder of all downlink users by mainboard and handles.

In the such scheme, the mutual data that are the processing of downlink user to the bit-level degree between master.In the data handling procedure of whole downlink user, if will regard an integral body as to the processing operand of whole down user data, the processing operand of bit-level only accounts for 30% of whole operand, 70% operand all is-symbol level is handled, so slave plate can not be well shared the processing operand of the data of whole downlink user in the existing scheme.

Consult Fig. 2 and Fig. 3, Fig. 2 and Fig. 3 are the implementation methods of uplink baseband resource pool in the prior art LTE base station, and the uplink baseband resource pool has two baseband boards: mainboard and slave plate, mainboard are the baseband board of redaction, and slave plate is the baseband board of early version.Main control module is given mainboard and slave plate with the information repeated configuration of the up user in the sub-district; Perhaps, user profile is disposed respectively to mainboard and slave plate according to load balancing; Mainboard L2 scheduler module is according to load balancing, and the up user that current Transmission Time Interval (TTI, Transmission Time Interval) is needed to handle distributes to mainboard and slave plate is handled; Mainboard and slave plate are respectively to the up user's that distributes Physical Uplink Shared Channel (PUSCH, Physical Uplink Shared Channel), Physical Uplink Control Channel (PUCCH, Physical Uplink Control Channel) and measuring reference signals (SRS, Sounding Reference Signal) channel institute data carried by data handle.

The implementation in above-mentioned ascending resource pond, three problems are arranged: first, when a plurality of user's frequency domain resource are multiplexing, public processing section is arranged between a plurality of users, collaborative process also helps performance boost between a plurality of in addition users, if these a plurality of users are distributed on the different plates, will cause double counting, the waste hardware resource.Second, the PUSCH channel is considered coordinate multipoint (COMP, when Coordinated Multi-Point) cooperating scene, if doing resource pool according to the user distributes, and interior two users of channel are dispensed on different plates and handle, the COMP data need be transmitted many parts, and the interference mitigation (IC, Interference Canceling) of operation do to(for) the COMP minizone is also inconvenient.The 3rd, can only use the L2 scheduler module centralized dispatching of mainboard, each baseband board can not independently be dispatched, and resource is wasted in the scheduling that can not walk abreast easily.

The present invention is described in detail below in conjunction with drawings and embodiments.

Consult Fig. 4, Fig. 4 is the flow chart of implementation method one execution mode of downgoing baseband resource pool in the LTE of the present invention base station, comprising:

Step S101: the information of the downlink user that main control module has disposed respectively according to mainboard and slave plate, dispatch the channel of corresponding downlink user to mainboard and slave plate.

Main control module is the module of in the LTE base station down base band resource pool mainboard and slave plate being controlled, dispatch, being disposed, for example: to mainboard and slave plate difference configurating downlink user's information; To mainboard and slave plate difference dispatching downlink user's channel, handle for mainboard and slave plate; To mainboard and slave plate difference allocating cell information; According to the disposal ability that reaches baseband board (mainboard or slave plate), revise parameter of sub-district or the like.After increasing baseband board in the LTE base station, the baseband board that the automatic identification of main control module meeting increases newly and the disposal ability of this baseband board.

Mainboard and slave plate are the baseband boards of LTE base station, represent new baseband board and old baseband board usually, and the quantity of mainboard and slave plate is determined according to practical situations.

Downlink user is meant that the base station sends the user of information to user's subscriber equipment.Need to prove that downlink user herein can be the downlink user of same sub-district, also can be the downlink user of different districts.

Channel is the passage of message transmission, when promptly information is transmitted a path of process.

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

Main control module is mainboard and slave plate configurating downlink user's a information respectively according to mainboard and the slave plate discerned in advance.According to the information of the downlink user that has disposed respectively, main control module is dispatched the channel of corresponding downlink user to mainboard and slave plate, so that mainboard and slave plate are handled data carried by data on the channel.

Step S102: the channel institute loaded information of the downlink user that mainboard and slave plate have been dispatched to main control module is respectively carried out the processing of bit-level and symbol level, obtains the time domain data that time domain data that mainboard produces and slave plate produce.

Bit-level is handled and mainly to be comprised: (Transport Block, CRC TB) is additional, sub-piece is cut apart and CRC is additional, the chnnel coding of chnnel coding, rate-matched, code block cascade, control information and rate-matched, business datum and control information are multiplexing, channel interleaving and data bit scrambling etc. for transmission block.

Symbol level is handled and is mainly comprised: the bit after the chnnel coding in each code word of transmitting on physical channel is carried out scrambling; Bit after the scrambling is modulated, obtained complex modulation symbols; Resulting complex modulation symbols is mapped in one or more transport layers; Every layer complex modulation symbols is carried out precoding; Complex modulation symbols on each antenna port is mapped in the resource unit (RE, Resource Element); On each antenna port, produce the time-domain signal of plural number.

Time domain is the fundamental property of signal, can know influencing each other between reaction signal and the interconnection line.Mainboard carries out the processing of bit-level and symbol level to the channel institute loaded information of the downlink user that main control module has been dispatched, obtains the time domain data that mainboard produces; Slave plate carries out the processing of bit-level and symbol level to the channel institute loaded information of the downlink user that main control module has been dispatched, obtains the time domain data that slave plate produces.

LTE of the present invention base station is at the downgoing baseband resource pool, respectively mainboard and slave plate are configured downlink user information according to downlink user, mainboard and slave plate carry out the processing of bit-level and symbol level to the channel of the downlink user of distribution, in this way, can rationally utilize the disposal ability of mainboard and slave plate.

Consult Fig. 5 to Fig. 7, Fig. 5 to Fig. 7 is the flow chart of implementation method three execution modes of downgoing baseband resource pool in the LTE of the present invention base station, comprising:

Step S201: main control module is respectively to mainboard and slave plate configurating downlink user's information.

Main control module is mainboard and slave plate difference configurating downlink user's information according to mainboard and the slave plate discerned.

Main control module is the module of in the LTE base station down base band resource pool mainboard and slave plate being controlled, dispatch, being disposed.

Step S202: the information of the downlink user that main control module has disposed respectively according to mainboard and slave plate, dispatch the channel of corresponding downlink user to mainboard and slave plate.

According to the information of the downlink user that has disposed respectively, main control module is dispatched the channel of corresponding downlink user to mainboard and slave plate, so that mainboard and slave plate are handled data carried by data on the channel.

Main control module can be dispatched the channel of corresponding downlink user according to two kinds of situations respectively to mainboard and slave plate when mainboard and slave plate are dispatched the channel of corresponding downlink user, be respectively:

First kind of foundation: downlink user information and load balancing that main control module has disposed respectively according to mainboard and slave plate, the channel of the downlink user that need handle to the current Transmission Time Interval TTI of mainboard and corresponding its loading condition of slave plate scheduling.

Transmission Time Interval (TTI) is at universal mobile telecommunications system (UMTS, Universal Mobile Telecommunications System) and a parameter in other digital telecommunication network (as the LTE system), be meant the length of an independent decoding transmission in Radio Link.TTI is relevant with the size of data block from higher network layer to radio link layer.It is the base unit of RRM (for example scheduling etc.) time of administering.The corresponding business of each transmission channel, owing to the requirement difference of miscellaneous service to time delay, so its TTI is different, TTI can be 10ms, 20ms, 40ms or 80ms etc.

Load balancing is meant the roughly equilibrium of downlink user number of load respectively of mainboard and slave plate, for example, the downlink user number that main control module disposes to the mainboard load is 10, it is 5 that the downlink user number of slave plate load is given in configuration, at this moment, according to load balancing, main control module is dispatched the channel of the downlink user that the current TTI of corresponding slave plate loading condition need handle to slave plate.

Second kind of foundation: the downlink user information that main control module has disposed respectively according to mainboard and slave plate, and the characteristic of the disposal ability of mainboard and slave plate or support, to the channel of the downlink user of the characteristic of mainboard and corresponding its disposal ability of slave plate scheduling or support.

The disposal ability of mainboard and slave plate, for example, the flow of mainboard is 500M, the flow of slave plate is 300M, at this moment, the channel dispatch that in the downlink user requirement of flow is lower than the downlink user of 300M can be handled to slave plate, the requirement to flow in the downlink user is handled to mainboard greater than the channel dispatch of the downlink user of 300M.

The characteristic that mainboard and slave plate are supported has for example been used the new characteristic of product in the downlink user, when slave plate can't be handled, can handle to mainboard to the channel that mainboard is dispatched this downlink user.

In actual applications, can take all factors into consideration the disposal ability of mainboard and slave plate and the characteristic of mainboard and slave plate support, perhaps only consider the disposal ability of mainboard and slave plate, perhaps only consider the characteristic that mainboard and slave plate are supported.

Main control module can be selected two kinds of above-mentioned foundations according to practical situations when mainboard and slave plate are dispatched the channel of corresponding downlink user.

Step S203: the channel institute loaded information of the downlink user that mainboard and slave plate have been dispatched to main control module is respectively carried out the processing of bit-level and symbol level, obtains the time domain data that time domain data that mainboard produces and slave plate produce.

Bit-level is handled and mainly to be comprised: the CRC of transmission block is additional, sub-piece is cut apart and CRC is additional, the chnnel coding of chnnel coding, rate-matched, code block cascade, control information and rate-matched, business datum and control information are multiplexing, channel interleaving and data bit scrambling etc.

Symbol level is handled and is mainly comprised: the bit after the chnnel coding in each code word of transmitting on physical channel is carried out scrambling; Bit after the scrambling is modulated, obtained complex modulation symbols; Resulting complex modulation symbols is mapped in one or more transport layers; Every layer complex modulation symbols is carried out precoding; Complex modulation symbols on each antenna port is mapped in the resource unit; On each antenna port, produce the time-domain signal of plural number.

Step S203 specifically comprises:

Step S203a: the Physical Downlink Shared Channel PDSCH institute loaded information of the downlink user that mainboard and slave plate have been dispatched to main control module is respectively carried out the processing of bit-level and symbol level.

Or step S203b: Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel) institute's loaded information of the downlink user that mainboard and slave plate have been dispatched to main control module is respectively carried out the processing of bit-level and symbol level.

Step S204: the time domain data that slave plate produces to mainboard transmission slave plate.

Slave plate carries out the processing of bit-level and symbol level to the channel institute loaded information of the downlink user that main control module has been dispatched, obtains the time domain data that slave plate produces.Slave plate is transferred to mainboard with the time domain data that produces.
