Embodiment

For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.

Fig. 1 is the flow chart of data transmission method embodiment mono-provided by the invention.The data transmission method of the present embodiment is applicable to RN realizes the scene of the data retransmission between UE and base station by time division multiplexing mode.As shown in Figure 1, the method for the present embodiment, comprising:

101, RN adopts the first sub-frame configuration type, carries out the mutual of data transmit-receive with DeNB.

102, described RN adopts the second sub-frame configuration type, carries out the mutual of data transmit-receive with UE; Wherein, described the first sub-frame configuration type is different from the second sub-frame configuration type.

Particularly, the first sub-frame configuration type, refers to the sub-frame configuration type on the return link being configured between DeNB and RN; The second sub-frame configuration type, refers to the sub-frame configuration type on the access link being configured between RN and UE.The first sub-frame configuration type is from second sub-frame configuration type is different refers to: both can adopt different subframe proportionings, or both adopt identical subframe proportioning, but sub-frame offset difference.Wherein, subframe proportioning refers to the ratio of ascending-descending subframes number in a frame, and the subframe type of each standard has a corresponding subframe proportioning.

In existing relaying technique, return link and access link use identical frequency range, for fear of self-interference, RN can not receive the upstream data that UE sends in the time receiving the downlink data of base station transmission, or RN can not send downlink data to UE in the time sending upstream data to base station simultaneously.Fig. 2 a is the operation principle schematic diagram of existing RN data transfer mode.As shown in Figure 2 a, existing data transfer mode is: at time slot (1), DeNB sends downlink data to RN; At time slot (2), RN sends downlink data to UE; Receive at time slot (3) RN the upstream data that UE sends; Receive at time slot (4) DeNB the upstream data that RN sends; Wherein, time slot (1), time slot (2), time slot (3) and time slot (4) are respectively 4 different time slots.In order to ensure this data transfer mode, it is the sub-frame configuration type of RN configuration that existing relaying technique requires DeNB on return link, be that the sub-frame configuration type of UE configuration is identical, and subframe proportioning adopts one of seven kinds of standard configurations with RN on access link.Table 1 is the ascending-descending subframes switching point allocation list of standard.As shown in table 1, wherein D represents downlink transfer subframe, and U represents uplink subframe, and S represents special subframe.Special subframe is made up of DwPTS, GP, UpPTS, and DwPTS is for downlink transfer, and UpPTS is for uplink, and the length of DwPTS and UpPTS can be joined.

And in embodiments of the present invention, for return link configures the first sub-frame configuration type, and for access link configures the second sub-frame configuration type that is different from the first sub-frame configuration type, also, on return link and access link, configure respectively different sub-frame configuration types.RN adopts the first sub-frame configuration type and DeNB to carry out the mutual of data transmit-receive, adopts the second sub-frame configuration type and UE to carry out the mutual of data transmit-receive, has realized RN and has received and dispatched up-downgoing data function simultaneously.RN receives and dispatches up-downgoing data function simultaneously, refers to, at synchronization, RN, in receiving the downlink data of DeNB transmission, can receive the upstream data that UE sends; Or RN, in sending upstream data to DeNB, can send downlink data to UE.Fig. 2 b is the operation principle schematic diagram of data transmission method embodiment mono-provided by the invention.As shown in Figure 2 b, receive the downlink data of DeNB transmission and the upstream data that UE sends at time slot (a) RN simultaneously; Send upstream data and send downlink data to UE to DeNB simultaneously at time slot (b) RN.Time slot (a) and time slot (b) are two different time slots.

The data receiving-transmitting method that the embodiment of the present invention provides, be configured by sub-frame configuration type and related signaling to return link and access link, for return link configures the first sub-frame configuration type, is different from the second sub-frame configuration type of the first sub-frame configuration type for access link configuration, make RN in adopting the first sub-frame configuration type and DeNB to carry out data transmit-receive mutual, can adopt the second sub-frame configuration type and UE to carry out the mutual of data transmit-receive, realized RN and received and dispatched up-downgoing data function simultaneously, system spectral resources utilance is high.

On the basis of above-described embodiment, whether open RN and receive and dispatch up-downgoing data function simultaneously, and when to open be optional, opening or close this function can be determined by RN or network side.Wherein, network side refers to DeNB or Operation and Maintenance (Operation and Maintenance is called for short OAM).In the time that DeNB or RN determine open or close this function, the instruction of being opened or closing RN and received and dispatched up-downgoing data function simultaneously by transmission, notifies corresponding RN or this function of DeNB On/Off.It should be noted that, OAM also can realize the data receiving-transmitting method of any embodiment of the present invention.

The implementation of simultaneously being received and dispatched up-downgoing data function by RN or DeNB decision unlatching RN at least can comprise following three kinds of modes:
