Embodiment
In order to solve the problems referred to above that prior art exists, the embodiment of the invention provides a kind of technical scheme to the RN control information transmission, by being the general network identities of a plurality of RN distribution, and use this general network identity to send control information at a plurality of RN, make a plurality of RN under the DeNB control can receive this control information, thereby improve the efficiency of transmission of backhaul link, and then improve the backhaul resource utilization.
In the embodiment of the invention, the control information that need send to RN is meant at each target RN all needs the information with identical content that sends, this control information can comprise one of following or combination in any:
Part system control signaling information comprises wireless resource configuration, or/and the content of SIB (system broadcast message) 13, or/and the other system broadcast content relevant with RN;
The configuration information in MBSFN zone comprises MBSFN area I D, session (session) information, PMCH (Physical Multicast Channel, Physical Multicast Channel) assignment information content;
Other need send to the control signaling information of RN.
Below in conjunction with the accompanying drawing in the embodiments of the invention, the technical scheme in the embodiments of the invention is clearly and completely described, obviously, the embodiments described below only are the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of embodiments of the invention protection.
In the embodiment of the invention, RN disposes two kinds of network identities (RNTI), and a kind of is the network identity of each RN special use, is used for RN of unique identification, C-RNTI for example, and perhaps other can distinguish the sign of this RN; A kind of is the shared network identities of a plurality of RN, can identify a plurality of (or one group) RN, R-RNTI for example, and promptly a plurality of RN have identical R-RNTI.These two kinds of network identities can be when the RN connecting system, and (or any moment after inserting) disposed by network side (as DeNB), perhaps other modes are obtained from network side, perhaps before connecting system, pass through manual type, or the mode of system's regulation, or other modes are pre-configured in RN.
Fig. 3 shows when the RN connecting system dedicated network sign (C-RNTI) that will be distributed for RN by DeNB and universal network and identifies (R-RNTI) and be configured to process among the RN.As shown in the figure, when the RN connecting system, DeNB can will send to this RN for C-RNTI and the R-RNTI that this RN distributes by dedicated control signaling.Wherein, DeNB can distribute C-RNTI and R-RNTI by once being configured to RN, promptly will send to RN for C-RNTI and the R-RNTI that RN distributes by a signaling, perhaps be configured to RN and distribute C-RNTI and R-RNTI by independent twice, promptly will send to RN for the C-RNTI that RN distributes, will send to RN for the R-RNTI that RN distributes by a signaling again by a signaling.
After RN configure dedicated network identity and the universal network sign, can use the dedicated network sign to receive network side, perhaps use the dedicated network sign to send control information or the data message relevant with this RN to network side at control information or data message that this RN sends.RN can also use universal network sign to receive the control information of the identical content that DeNB sends at this RN and other RN that disposes this universal network sign.
Wherein, based on the dedicated network sign of RN, the process that RN and network side communicate can realize according to the message transmission mechanism of existing RN and network side; Universal network sign based on RN, the information transmission mode of RN and network side, can be: DeNB will need to be carried on the control signaling to the control information of the identical content of a plurality of RN transmissions, and the universal network of using RN identifies, at the appointed time sends this control signaling, the RN that disposes this universal network sign at the appointed time uses the universal network sign to receive this control signaling, thereby gets access to the control information of wherein carrying.
Fig. 4 shows the process of a kind of universal network sign based on RN to the RN control information transmission, wherein, RN under the DeNB control has disposed universal network sign (R-RNTI), when network side need send the control information of identical content to all RN under its control, as needs when these RN send MBSFN area configurations information, as shown in the figure, this process can comprise:
The MBSFN area configurations information-bearing that step 401, DeNB will need to send is in the control signaling, and the R-RNTI of use RN sends this control signaling.
In this step, DeNB can use the R-RNTI of RN that the control signaling is carried out scrambler, sends this control signaling at the MBSFN of appointment subframe time slot.This control signaling can be PDCCH (PhysicalDownlink Control Channel, Physical Downlink Control Channel) signaling, also can be MAC (MediaAccess Control, media interviews control) layer signaling, can also be RRC (Radio ResourceControl, Radio Resource control) layer signaling.
Step 402, RN use R-RNTI to go to receive the control signaling that DeNB sends in the time of appointment.
In this step, RN is the control signaling of removal search DeNB transmission at the appointed time, and the control signaling of using the R-RNTI descrambling to search.For the RN that disposes this R-RNTI, this control signaling that can descrambling searches, and can further obtain the MBSFN area configurations information that DeNB sends by resolving this control signaling.
In the above-mentioned flow process, DeNB control each RN down receives the time that DeNB employing R-RNTI sends control signaling, and can be disposed by network side, as being configured by DeNB when the RN connecting system; Perhaps before sending corresponding control signaling, notify, notify the RN time of reception by dedicated control signaling as DeNB by DeNB; Perhaps specify in agreement (in the standard).
Based on identical technical conceive, the embodiment of the invention also provides a kind of via node equipment and base station equipment.
