The method that is used for the resource that PDCCH sends in the eNB mapping will briefly be described in the LTE system below.

Usually, eNB can send scheduling assignment information and other control information through PDCCH.Can in the polymerization of one or more a plurality of CCE, send physical control channel.A CCE comprises nine resource element groups (REG).The quantity that is not assigned with the REG of the automatic repeat requests indicating channel of Physical Control Format Indicator Channel (PCFICH) or physics (PHICH) is N _REGThe CCE that can in system, use is 0 to N _CCE-1 (at this,

).PDCCH supports a plurality of forms as shown in table 2.By n continuously a PDCCH constituting of CCE begin (at this, i representes CCE number) from the CCE that is used to carry out i pattern n=0.Can send a plurality of PDCCH via a sub-frame.

[table 2]

The PDCCH form	The quantity of CCE	The quantity of resource element group	The quantity of PDCCH bit
				0	1	9	72
1	2	18	144
				2	4	36	288
3	8	72	576

With reference to table 2, eNB can depend on what the Region control information of transmission is confirmed the PDCCH form.In addition, UE is that unit reads control information etc. with CCE, thereby reduces expense.Similarly, via node can be that unit reads control information etc. with CCE.In the LTE-A system, resource element (RE) can be that unit shines upon with relay and control channel element (R-CCE), to send R-PDCCH to any via node.

With reference to (b) of Fig. 4, sub-frame of uplink can be divided into controlled area and data field in frequency domain.The controlled area is assigned to the Physical Uplink Control Channel (PUCCH) that carries ascending control information.The data field is assigned to the Physical Uplink Shared Channel (PUSCH) that carries user data.In order to keep single-carrier property, a UE does not send PUCCH and PUSCH simultaneously.The RB that the PUCCH of a UE is assigned in the sub-frame is right.Belong to the right RB of RB and occupy different subcarriers to two time slots.Thereby the RB that distributes to PUCCH is to carrying out " frequency hopping " at boundary of time slot.

Fig. 5 is the figure that the time-frequency resources network of the down link that uses among the present invention is shown.In the downlink signal transmitted from each slot can be used include

changes according to the downstream transmission bandwidth that disposes in the sub-district; And should satisfy

at this; The minimum downlink bandwidth that

expression wireless communication system is supported, the maximum downstream bandwidth that

expression wireless communication system is supported.Despite and

but the present invention is not limited thereto.The quantity that can change the OFDM symbol that comprises in the time slot according to the length and the subcarrier spacing of Cyclic Prefix (CP).Under the situation that multi-antenna transmitting is failed, can resource grid of each antenna port definition.

Be called as resource element (RE) to each element in the resource grid of each antenna port, and through the index in the time slot to (k is l) by sign uniquely.At this; K representes the index of frequency domain; L representes the index of time domain, and k has 0 ... Any value in

; L has 0 ... And any value in

and

can be predetermined value.For example,

and

can be given as shown in table 3ly.Therefore, a PRB comprises

individual RE.PRB time domain corresponding to a time slot and in frequency domain corresponding to 180kHz, but the invention is not restricted to this.

[table 3]

PRB has from 0 value in

scope at frequency domain.The quantity n of PRB in frequency domain _PRB(k, the relation between l) satisfies with RE in the time slot

The size of VRB equals the size of PRB.VRB can be divided into centralized VRB (LVRB) and distributed VRB (DVRB).For the VRB of each type, a pair of VRB that is arranged in two time slots of a sub-frame is assigned with single VRB n _VRB

VRB can have the size identical with PRB.Defined two types VRB: first type is centralized VRB (LVRB), and second type is distributed VRB (DVRB).For various types of VRB, on two time slots of a sub-frame, distribute VRB right with single VRB index (being called as hereinafter VRB number).In other words;

the individual VRB that belongs to first time slot between two time slots that constitute a sub-frame is assigned with from 0 any index to , and

the individual VRB that belongs to second time slot between two time slots is distributed from 0 any index to

similarly.

Can be applicable between eNB and the via node to radio frame structure, descending sub frame and the sub-frame of uplink of Fig. 5 description, the time-frequency resources network of down link etc. with reference to Fig. 3.

Hereinafter, with describing in the LTE system from the processing of eNB to UE transmission PDCCH.The eNB basis will be confirmed the PDCCH form to the DCI that UE sends, and to control information additional cycles redundancy check (CRC).According to all sides or the purposes of PDCCH, CRC is carried out mask with Radio Network Temporary Identifier symbol (RNTI).If PDCCH is used for particular UE, then can be with the unique identifier mask of UE to CRC.If R-PDCCH is used for the given trunk node, then can with the unique identifier of this via node for example sub-district-RNTI (C-RNTI) mask to CRC.Alternatively, if PDCCH is used for beep-page message, then can be with paging indicator identifiers (P-RNTI) mask to CRC.If PDCCH or R-PDCCH are used for system message, then can be with system message identifier and system message RNTI (SI-RNTI) mask to CRC.In order to indicate as response to UE or via node transmission random access guiding, can be with inserting RNTI (RA-RNTI) mask at random to CRC.Table 4 illustrates the example of mask to the identifier of PDCCH and/or R-PDCCH.

[table 4]

If C-RNTI is used; Then PDCCH or R-PDCCH carry the control information that is used for corresponding particular UE or given trunk node; And if another RNTI is used, then PDCCH or R-PDCCH carry the common control information that is received by whole or a plurality of UE in the sub-district or via node.ENB carries out chnnel coding to the DCI that has been added CRC, and produces through coded data.ENB carries out rate-matched according to the quantity of distributing to the CCE of PDCCH or R-PDCCH form.Afterwards, eNB modulates through coded data and produces modulated symbol.ENB arrives physics RE with modulated sign map.

Although existing 3GPP LTE version 8 (comprising version 9) system is based on based on transmission and reception on the single carrier frequency band of scalable frequency band size; But the LTE-AS can be supported to use in the identical time-domain resource (just; In subframe unit) one or more a plurality of carrier frequency bands on frequency domain resource (just, subcarrier or Physical Resource Block (PRB)) from the sub-district or eNB to the descending transmission of UE.

Similarly; The LTE-AS can be supported to use in the identical time-domain resource (just; In subframe unit) one or more a plurality of carrier frequency bands on frequency domain resource (just, subcarrier or Physical Resource Block (PRB)) from the up transmission of any UE to sub-district or eNB.These are called as descending carrier polymerization and up-link carrier polymerization respectively.Fig. 6 and Fig. 7 show and are used to send the physical layer (PHY) of the up of a plurality of distribution or descending carrier frequency band and the structure of layer 2 (layer 2 (MAC)) from the angle of arbitrary cells or UE.

(a) illustration of Fig. 6 the notion of a plurality of carrier waves among a plurality of MAC layer-management eNB, (b) illustration of Fig. 6 the notion of a plurality of carrier waves among a plurality of MAC layer-management UE.

Shown in Fig. 6 (a) and Fig. 6 (b), the MAC layer can be controlled carrier wave 1:1.In the system that supports multicarrier, carrier wave can be used continuously or discontinuously, no matter is up link or down link.The TDD system is configured to manage and includes descending and N carrier wave uplink; The FDD system is configured to use a plurality of carrier waves respectively in up link and down link.The FDD system can support asymmetric carrier aggregation, and is wherein different by the bandwidth of the quantity of the carrier wave of polymerization and/or carrier wave in up link and down link.

The notion of a plurality of carrier waves among a MAC layer-management of (a) illustration eNB of Fig. 7, the notion of a plurality of carrier waves among a MAC layer-management of (b) illustration UE of Fig. 7.

With reference to (a) of Fig. 7 and (b) of Fig. 7, one of MAC layer-management or more a plurality of frequency carriers are to send and to receive.Because the frequency carrier by a MAC layer-management must not be continuous, therefore resource management more flexibly is possible.In Fig. 7 (a) and Fig. 7 (b), for ease, a PHY layer means a CC.At this, a PHY layer must not mean independently radio frequency (RF) device.Usually, one independently the RF device mean a PHY layer, but be not limited to this.A RF device can comprise several PHY layers.

The a series of Physical Downlink Control Channel (PDCCH) that are used for sending the control information of L1/L2 control signaling can send under the state of the physical resource that is mapped to independent CC, and the control information that this L1/L2 controls signaling is from the packet scheduler generation of the structure of support Fig. 7 of MAC layer (a) and Fig. 7 (b).At this moment; Particularly; Authorize the phase related control information, or with unique PDSCH or separately a plurality of PDCCH of the Channel Assignment that is associated of the transmission of the Physical Uplink Shared Channel (PUSCH) of UE divided according to the CC that sends Physical Shared Channel; Be encoded and be generated as the PDCCH through dividing, this is called as the PDCCH of independent coding.As another method, the control information that is used to send the Physical Shared Channel of several component carriers can be built as a PDCCH and be sent out, and this is called as the PDCCH of combined coding.

In order to support descending or the up-link carrier polymerization; ENB can distribute and wants CC measured and/or report; The preparation that is used to send the link of PDCCH and/or PDSCH as foundation is handled, and makes the PDCCH that is used to send data and control information and/or PDSCH basis be sent out based on the situation of each particular UE or via node if perhaps set up link.This is distributed by the CC that is used for any purpose expresses.At this moment; ENB can the RRC signaling that dynamic characteristic is special-purpose via a series of UE or RN is special-purpose (UE special use or the special-purpose RRC signaling of RN) according to control send the CC assignment information under the situation that the CC assignment information is controlled by L3 RRM (RRM), perhaps can perhaps send the CC assignment information via a series of Dedicated Physical Control Channels that are used for only sending control information as L1/L2 control signaling via a series of PDCCH.

As another kind of method; Be grouped in the CC assignment information under the situation of scheduler control, can send the CC assignment information as L1/L2 control signaling or via a series of Dedicated Physical Control Channels that are used for only being used to sending control information or the PDCCH of L2MAC message format via a series of PDCCH.

Fig. 8 illustrates the figure of CC that configuration in eNB in the LET-A system or the via node zone is connected to down link and the up link of UE or via node.

With reference to Fig. 8, show the descending CC and the up CC of any eNB or via node distribution arbitrarily.For example, the quantity of descending CC is that the quantity of N and up CC is M.At this, the quantity of descending CC can equal or be different from the quantity of up CC.

In the LTE-A system, descending CC can be classified as three types.As first kind of CC, there is the backward compatibility CC of the backwards compatibility of support and LTE rel-8UE.As second kind of CC, existence can not be by the non-backward compatible CC of LTE UE visit (that is, only supporting LTE-AUE).In addition, as the third CC, there is expansion CC.

Backward compatibility CC as first kind of CC is the CC that not only sends PDCCH and PDSCH but also transmission reference signal (RS), primary synchronization channel (P-SCH)/auxiliary synchronization channel (S-SCH) and main broadcast channel (P-BCH) according to the LTE structure in the above, can support LTE UE visit.

Send the CC of PDCCH, PDSCH, RS, P-SCH/S-SCH and P-BCH in the above with the form of revising as the non-backward compatible CC of second kind of CC, to forbid LTE UE visit.

First kind of CC (that is, backward compatibility CC) makes that LTE UE and LTE-A UE can visited cell (perhaps eNB), and second kind of CC (that is non-backward compatible CC) only makes that LTE-A UE can visited cell.Expansion CC as the third CC forbids the UE visited cell and is called as first kind of CC or the auxiliary CC of second kind of CC.P-SCH/S-SCH, P-BCH and PDCCH do not send on the expansion CC as the third CC; And whole resources of the third CC can be used for sending PDSCH to UE, perhaps can be in sliding-modes (slip mode) operation down when not to the PDSCH scheduling resource.ENB or via node do not send control information to UE via the third CC.

That is to say, first kind of CC and second kind of CC can be set up a sub-district necessary or can dispose the independent CC type of a sub-district, the third CC can be the independent CC with or more a plurality of independent CC coexistences.

In the present invention, as the method for in based on the wireless communication system of sub-district, supporting via node, the method for multiplexing eNB shown in Figure 1 and back haul link between the via node and the access link between via node and the UE has been proposed.Particularly; Can consider to use frequency division multiplexing (FDM) scheme multiplexing to back haul link and access link on frequency axis; Send and receive via the signal of back haul link between via node and eNB supporting simultaneously, and send and receive via the signal of access link between via node and UE.Although the via node based on the LTE-A system has been described the present invention, the present invention can be applicable to the general mobile radio system based on the sub-district.

In the LTE-A system, introduce the Class1 via node as via node.The Class1 via node has unique Physical Cell Identifier symbol (ID).The Class1 via node has the ability of carrying out repertoire eNB, that be used to send the whole physical channels such as PDSCH, P-SCH, S-SCH, PDCCH and PBCH.The Class1 via node looks it is an eNB from the angle of UE.Just, the via node type of such wireless backhaul eNB is called as the Class1 via node: this wireless backhaul eNB is via the back haul link of the radio link configuration that is connected with eNB with higher server.

Because the via node of Class1 is used as an eNB and carries out work in the LTE-A system; Therefore the via node of Class1 should be supported backward compatibility (just; Should support the LTE system); This is the requirement to the LTE-A system, and therefore should send the common reference signal (CRS) of LTE version 8 via the access link of each subframe.At this moment, if the access link between back haul link between eNB and the via node and via node and the UE is operated on identical carrier frequency, then the communication performance of via node maybe deterioration.That is to say, if via node receives signal via back haul link from eNB, and send signal via access link to UE simultaneously, then communication performance maybe be owing to self disturb and obvious deterioration.In order to solve the deterioration of communication performance, can consider frame structure shown in Figure 9.

Fig. 9 illustrates to be used for the LTE-A system and to use the TDM scheme to come the figure of the structure of multiplexing and the frame of supporting back haul link and access link.

As shown in Figure 9, can use multiplexing access link of Time Division Multiplexing scheme and back haul link and via node to introduce pseudo-MBSFN subframe 910, be used for the backward compatibility back haul link and receive.Yet this method is disadvantageous, owing to must make amendment to the automatic repeat requests of the mixing of access link and back haul link (HARQ) two-way time (RTT).

This unfavorable in order to solve, in the present invention, propose to use the method for multiplexing back haul link of frequency division multiplexing (FDM) scheme and access link, so that via node can be supported back haul link and access link simultaneously in same sub.Particularly, with describing the multiplexing method that uses the FDM scheme according to above-mentioned CC type.

backhaul zone

In conjunction with Figure 10; If do not carry out backhaul transmission/reception via the descending/up backhaul zone (perhaps link) in the descending arbitrarily/sub-frame of uplink of via node, then repeater can use descending/up backhaul zone to carry out the transmission/reception of the access link of LTE-AUE.In the case, repeater can be via PDCCH zone 1016 receiving resource allocation informations of the downstream bands 1015 of supporting the LTE system.Although not shown among Figure 10, can prevent the predetermined protection frequency band that disturbs for the downstream bands 1015 of supporting the LTE system and the border branch between the descending
