Description
Technical field
The present invention relates to field of information transmission, be meant a kind of method, system, base station of notifying terminal to process message especially and carry out the terminal of Message Processing.
Background technology
Forward control channel is very important channel in communication process, and each frame all carries out message transmission, is mainly used in transmission access permission, resource assignation, replys message such as (ACK), power control.Be convenient and describe, below abbreviate forward control channel as control channel.Comprised in the control channel forward direction that is used for transmission resource management message share signaling channel (Forward Shared Signaling Channel, F-SCCH) and other channels.
(F-SBCCH is and the corresponding channel of main broadcast channel for Secondary BroadcastChannel, F-SBCCH) middle transmission at inferior broadcast channel for resource quantity that control channel takies and position.Usually, per two superframes, i.e. 48 frames resource quantity that the transmission primaries control channel takies on F-SBCCH and position, in the time of two superframes, the resource quantity of distributing to control channel remains unchanged.The resource quantity that takies estimates that with F-SCCH the maximum information number that carries is relevant, and the resource quantity that other subchannels in the control channel take remains unchanged substantially.
F-SCCH is used to transmit message such as access permission, resource assignation, comprises various control message, and as shown in table 1, these control messages length differ.In the time of need transmitting control message, each control messages zero padding can be become unified length, adopt identical code modulation mode then, and be used for medium access control (the Media Access Control of broadcast or multicast, MAC) (AccessTermination, MACID AT) carry out sending after scrambler is handled sign (MACID) or target terminal.Be called the control messages piece through the control messages after the above processing.All control messages pieces link together and constitute the control messages sequence, and the control messages sequence is mapped on the physical channel after interweaving.The quantity of the control messages piece of Fa Songing then before being mapped to physical channel, being added complete zero control messages piece and is reached needed length less than the systemic presupposition value after the control messages sequence if desired.Complete zero control messages piece does not comprise any control information, therefore can be described as the idle message piece, and relative therewith, the message blocks that has comprised control messages is called effective control messages piece.Can comprise the idle message piece in the control messages sequence.Owing to do not comprise any control information in the idle message piece, therefore,, can cause the waste on the resource to the transmission of idle message piece, when the quantity of idle message piece was many, this waste was particularly evident.
The structural representation of table 1 F-SCCH control messages
For the resource of waste is utilized, existing protocol has proposed the method for data channel shared control channel resource on the original basis, is about to idle message blocks takies in each frame of control channel resource, is that idling-resource is redistributed to data channel and used.
In order to reduce expense, at every turn according to the mixed automatic retransmission request (Hybrid Automatic RepeatRequest, when HARQ) retransmitting, the resource quantity that takies remains unchanged; Yet because control channel information transmitted difference, therefore, the untapped resource quantity of control channel is uncertain.Like this, share the transmission that the resource of using to data channel is preferably used in redundant information by control channel.Redundant information is meant those information that AT normal process business datum is not exerted an influence, and redundant information only is the performance that is used to improve business datum, that is to say, during the AT processing service data, even lack redundant information, still can correctly obtain business datum.
In order to realize the purpose of data channel shared control channel resource, (Access Network AN) needs the operating position of notice AT control channel (mainly being F-SCCH) to resource to access network, and further realizes the assignment to idling-resource.At present, (PacketData Control Assignment Message PDCAM), notifies the operating position of AT control messages piece to resource to AN by send bag Data Control assignment message to AT.
PDCAM indicates the operating position of control messages piece to resource by the method for bit indication (bitmap), be that the control messages number of blocks that comprises in the control messages sequence is when being N, need carry N bit among the PDCAM, whether each bit is used to identify corresponding control messages piece and is used.But because PDCAM adopts the operating position of bit sign control channel to resource, whether the control messages number of blocks that should comprise in the control messages sequence needs many PDCAM to be used to each control messages piece of AT full notification more for a long time.For example, the control messages piece adopts high-order modulating to transmit, and the resource of depositing a control messages piece originally can be carried a plurality of control messages pieces, and like this, the total quantity of control messages piece will be very many.At this moment, can determine corresponding control messages piece indicated among every PDCAM by the sub-mapping table call number (sub-bitmap index) shown in the table 1.Every PDCAM of transmission needs to take resource, when whether many PDCAM of needs transmission are used with each control messages piece of full notification AT, will cause excessively the taking of resource caused the waste on the resource.
In addition, (the former is called broadcast because each control messages piece all may carry out the scrambler processing with the MACID of broadcasting MACID or target AT, the latter is called unicast messages, effectively control messages comprises this two kinds of message), thus after AT receives the control messages sequence, may need twice of a control messages piece descrambling code, could determine whether this control messages piece is relevant with this AT, this must increase the load to AT, prolongs the AT control message processing required time of piece, reduces the handling property of AT.
In addition, give AT with the idling-resource assignment if desired, redundant information with transmission AT, then each assignment all needs to send a complete assignment message to AT, as forward link assignment message (FLAssignmentMessage, FLAM) etc., being used for the control messages piece that assignment idle message piece takies resource need additionally take resource, causes the waste to resource.
In sum, the effect and the transmission thereof of existing control messages piece make handling property very low.

Fig. 2 C shows PDCAM structural representation in the embodiment of the invention seven, shown in Fig. 2 C, in the present embodiment, AN transmits the broadcast control message piece on the desired location of control messages sequence, AN is transmission clean culture control messages piece on another desired location of control messages sequence further, and, the desired location of the control messages sequence of the current transmission broadcast control message of AN notice AT piece, and the clean culture control messages piece of transmission is at another desired location of control messages sequence.AN carries block type, broadcast control message number of blocks, clean culture control messages number of blocks and AT identity information in the PDCAM that AT sends.
After AT receives PDCAM, on the desired location of control messages sequence, according to the broadcast control message number of blocks broadcast control message piece is handled, promptly on the desired location of control messages sequence, the control messages piece is handled, use broadcasting MACID to broadcast control message piece descrambling code, the quantity of the corresponding control messages piece of handling is the broadcast control message number of blocks, on another desired location of control messages sequence, according to clean culture control messages number of blocks clean culture control messages piece is handled, use self MAC ID to clean culture control messages piece descrambling code, the quantity of the corresponding control messages piece of processing is clean culture control messages number of blocks; And, AT also need judge the AT identity information that whether comprises self in the AT identity information, if, then continue to determine at the desired location of control messages sequence and broadcast control message number of blocks, clean culture control messages number of blocks the position of idling-resource according to broadcast control message piece and clean culture control messages piece, determine the idling-resource of assignment then, this resource is used to self; Otherwise, finish current flow process.
When only carrying the broadcast control message number of blocks among the PDCAM, this broadcast control message number of blocks is replaceable to be clean culture control messages number of blocks, and concrete processing is identical substantially with above description, and just the corresponding change of descrambling code mode repeats no more herein.
When carrying effective control messages number of blocks among the PDCAM or not comprising the control messages number of blocks of control information, only need in PDCAM, to indicate quantity, can realize the function of PDCAM in the table 1, the information that needs the N bit to represent in having now only needs about log among the embodiment provided by the invention
2 NBit just can show.Because the The whole control channel need just be mapped to the actual physics channel through after interweaving, therefore, the scheme that various embodiments of the present invention provide can't produce any negative effect, and original diversity performance still can be good at satisfying.
When carrying broadcast control message number of blocks or clean culture control messages number of blocks among the PDCAM, AT can directly determine the descrambling code mode of corresponding control messages piece, it is incorrect and carry out the situation of descrambling code once more can not occur descrambling code mode that AT adopts again, improve the handling property of AT, compared with prior art reduced the load of AT.
When further carrying the AT identity information among the PDCAM, can realize assignment by a PDCAM to idling-resource, need not by independent assignment message idling-resource to be carried out assignment again, because an assignment message takies fundamental node resource (Base Node), like this, when saving M bar assignment message, just can save about M/3 to M/2 the shared resource of basic resources node, improve efficiency of transmission.
When above-described PDCAM transmits, the independent control allocated channel that is exclusively used in transmission PDCAM can be set, use this control allocated channel transmission PDCAM then; Also can use existing control channel (as F-SCCH) transmission PDCAM.
When PDCAM generates effective control messages piece, can not that order is through cyclic redundancy code (CyclicRedundancy Code, processes such as CRC) verification, coding, modulation, scrambler, but directly adopt the block encoding mode to generate effective control messages piece, and then transmit.For the relatively shorter PDCAM of length, the effect of block encoding mode is relatively good.Because the block encoding scheme is ripe prior art, is not described in detail specific implementation at this.
