Up-downgoing identification information

What up-downgoing identification information indicated scheduling is up or descending, can be represented with a bit.If IDMA be served only for it is up or be served only for it is descending, without interaction the information.

Scheduling subframe information

Assuming that 3rd subframe of the scheduling subframe in next radio frames, then scheduling subframe information " 011 " expression, if scheduling subframe has several subframes, scheduling subframe information can also be represented successively, and scheduling subframe informational message information format can be：The information such as the edge UE interleaver of the information such as edge UE interleaver of subframe numbers+scheduling+subframe numbers+scheduling+....Or, using bit diagram（Abbreviation bitmap) the scheduling subframe information of next radio frames is indicated, such as " 0111000010 ", represent in # " 1,2,3 and 8 " individual subframe up-regulation degree.Message format can be：The information such as the edge UE interleaver in Bitmap+ scheduling subframes.Scheduling subframe information can not also be notified in interaction, but be used default Method.Such as give tacit consent to a few subframe up-regulation degree in next radio frames.For example, acquiescence is the 2nd of next radio frames, 5th, edge UE is scheduled on 8 work song frames, then eNB can send an information and represent whether it dispatches in these subframes, such as represented using bitmap, such as " 011 ", first 0 represents without scheduling edge UE in the 2nd subframe, the 5th, 8 subframe up-regulation degree edge UE.The form of scheduling subframe information can be：The information such as the edge UE interleaver of the 8 subframe up-regulation degree of information+the such as edge UE interleaver of the 5th subframe up-regulation degree of 011+.The form of scheduling subframe information can also be other modes.Above-mentioned message format is not limited in actual applications.Or, can preset can only next radio frames some subframe scheduling edge UE, then the scheduling subframe information need not be then transmitted in X2 interface.

Resource allocation information

Assuming that system bandwidth is 5M, i.e., 25 RB, if the indicating means distributed using continuous resource, then need " log₂(25 X 26 / 2)>9 bit come indicate distribution resource.Can certainly be by the way of other resource allocation, such as bitmap, the present invention is not limited.

MCS information

Edge UE MCS information is, it is necessary to which 5bit represents the information.The usual bad channel conditions of edge UE, the MCS that can preset edge UE is fixed, such as QPSK signal（Abbreviation QPSK), 1/3 coding, then avoid the need for transmitting MCS information on X2 interface.

Demodulated reference signal information

Demodulated reference signal information is used for position and/or the sequence information for indicating demodulated reference signal, if the position of demodulated reference signal and/or sequence are fixed or only relevant with cell ID, the demodulated reference signal information need not be transmitted on X2 interfaces.

C-RNTI

Due to Physical Uplink Shared Channel (Physical Uplink Shared Channel, abbreviation PUSCH) and Physical Downlink Shared Channel (Physical Downlink Shared Channel, abbreviation PDSCH) scrambled using a scrambler sequence, and scrambler sequence is initialized with C-RNTI, the sequence of demodulated reference signal is also relevant with C-RNTI, it is possible that needing to exchange the UE of scheduling C-RNTI information.In other implementations, these information can also be generated without C-RNTI, such as ^ _ set PUSCH and PDSCH using the sequence of a cell-specific to scramble, that is this scramble sequence is relevant with cell ID, the sequence of demodulated reference signal and/or position are also only relevant with cell ID, C-RNTI is not needed to generate these information, then to avoid the need for transmitting C-RNTI on X2 mouthfuls. Redundancy version information

The redundancy version information of data, if edge UE version is arranged into a fixed value, such as existing redundancy versions have four kinds, one kind are fixed into for edge UE, then redundancy version information need not be transmitted on X2 interface.

Above-mentioned interleaver information and iterative detection reference information can also do corresponding simplification, such as assume that the edge UE of sub- frame in scheduling interleaver is just as, then each subframe just can only notify an interleaver information just can be with；Or assume that in the information that X2 interface is once transmitted, what the interleaver in all subframes was just as, then can only notify an interleaver just can be with the information that X2 interface is once transmitted.

The default cycle can be used by carrying out above-mentioned interaction by X2 interface in each embodiment of the invention, between eNB, for example, being carried out once every 20ms.

In each embodiment of the invention, the first eNB is received in the way of described in each embodiment after the information of the 2nd eNB transmissions, can also send the first eNB information to the 2nd eNB by the way of a kind of simplification.For example, first eNB is received after the interleaver information and iterative detection reference information of the 2nd eNB transmissions, in order that edge UE is matched, first eNB can dispatch edge UE with the 2nd eNB identicals running time-frequency resource, and the edge UE of the first eNB subordinate uses the interleaver different with the edge UE of the 2nd eNB subordinate on running time-frequency resource identical from the 2nd eNB.In the case, the information format that first eNB is sent can be sent using simplified form, for example, interaction is all only sent acquiescence in a fixed subframe of next radio frames every time, several resource allocations and corresponding interleaver information are listed by the 2nd eNB, for example： #0 ~ 5RB:Interleaver #1; #20 ~ 21RB:Interleaver #2; #28 ~ 32RB:Interleaver #3, in the present embodiment exemplified by only interacting interleaver information, iterative detection reference information can use predetermined manner.So that the first eNB has two edge UE to dispatch as an example, the resource that two UE take is respectively #20 ~ 21RB and #28 ~ 32RB, the interleaver of use is respectively #6 and #8, then the first eNB feeds back " 011+ interleaver #6+ interleavers #8 " to the 2nd eNB, wherein latter two resource in three resources sent before the 2nd eNB of interleaver correspondence of " 011 " expression below.Or, the first eNB can also give tacit consent to be sent in the first two resource, then the first eNB feeds back " interleaver #6+ interleavers #8 " to the 2nd eNB.If the first eNB does not have edge UE to need scheduling, interleaver information and iterative detection reference information can not be fed back to the 2nd eNB.
