Embodiment
The flow chart of the resource allocation indicating method of a kind of repeated link that Fig. 2 provides for the embodiment of the invention.In the present embodiment, suppose between eNB and RN that in advance mutual each comfortable relay sub-frame is toward its shared OFDM (Orthogonal Frequency Division Multiplexing, OFDM) symbolic number of control channel of sending of UE down.This method comprises:
Step 21, determine repeated link Physical Downlink Shared Channel (Relay link Physical Downlink Shared Channel, initial OFDM character position R-PDSCH);
Specifically can be according to Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH) with repeated link Physical Downlink Control Channel (Relay link Physical Downlink Control Channel, R-PDCCH) the OFDM symbolic number that takies is determined the initial OFDM symbol of R-PDSCH; The initial OFDM symbol of described R-PDSCH is positioned at before or after the OFDM symbol that described R-PDCCH takies; The initial OFDM symbol of described R-PDCCH is fixed;
Step 22, with initial each RN of OFDM character position information notification of described R-PDSCH; Perhaps, each RN is informed to the OFDM symbolic number that the PDCCH of UE takies in OFDM symbolic number that R-PDCCH is taken and base station, so that described each RN determines the initial OFDM character position of described R-PDSCH.
Wherein, the initial OFDM character position information of described R-PDSCH comprises the deviate of described R-PDSCH with respect to the initial OFDM symbol of R-PDCCH, and perhaps described information is included as the absolute value of the initial OFDM symbol of described R-PDSCH.R-PDCCH is the control channel of eNB to RN, and PDCCH is the control channel of eNB to UE, and perhaps RN is to the control channel of UE.
Above-mentioned steps 21, step 22 can be carried out by base station such as eNB.
In the above-mentioned steps 21, the original position of R-PDCCH is fixed in after the shared symbol of described PDCCH, be to relaying link physical control format indicating channel (Relay link Physical Control Format Indicator Channel for fear of the transmitting-receiving conversion, R-PCFICH), repeated link combining retransmission indicating channel (Relay link Physical hybrid-ARQ indicator channel, R-PHICH), the influence of downlink relay link control channels such as R-PDCCH, and with R-PCFICH, R-PHICH, downlink relay link control channels such as R-PDCCH are placed on the sign resources after RN finishes transmitting-receiving conversion as far as possible and send.The sign resources that RN finishes after the transmitting-receiving conversion does not comprise the sign resources that is used to receive and dispatch conversion.On the one hand, because in the repeated link subframe, the PDCCH symbolic number that RN is sent to UE is no more than 2, and the time of finishing the transmitting-receiving conversion be no more than 1 OFDM symbol, therefore, the control channel primary sign of RN can be placed on the 3rd sign resources.On the other hand, must be placed on owing to the downlink relay link control channel on the PDCCH sign resources afterwards of tie link, and the PDCCH number of tie link is with system bandwidth
Figure B2009101747247D0000051
Difference, account for 3 and 4 sign resources at most respectively.Take all factors into consideration aforementioned two aspect factors, and under the situation that does not increase the overhead between eNB and the RN, the primary sign of downlink relay link control channel fixedly can be following two kinds of situations:
When
Figure B2009101747247D0000052
The time, R-PCFICH, R-PHICH, R-PDCCH shine upon from the OFDM sign-on of l=4, are about to give R-PCFICH, R-PHICH, R-PDCCH from the OFDM allocation of symbols that l=4 begins;
When
Figure B2009101747247D0000053
The time, R-PCFICH, R-PHICH, R-PDCCH shine upon from the OFDM sign-on of l=3, are about to give R-PCFICH, R-PHICH, R-PDCCH from the OFDM allocation of symbols that l=3 begins.
Change according to different system bandwidth and traffic carrying capacity because the shared sign resources of control channel of tie link is several, the dynamic change between 1～3 or 2～4 of the number of its shared OFDM symbol, and the original position of downlink relay link control channel is fixing, therefore, utilize the resource of downlink relay link for optimization, R-PDSCH can be by eNB according to the required OFDM symbolic number that takies of the various control channels that comprise repeated link and tie link in the relay sub-frame, dynamically the primary sign of decision R-PDSCH improves resource utilization effectively.
The OFDM symbolic number that eNB takies according to the control channel PDCCH to its following UE
Figure B2009101747247D0000061
And the OFDM symbolic number N that takies according to control channel R-PDCCH to RN R-PDCCH, the primary sign position of decision R-PDSCH resource mapping.Particularly, eNB remove send to its down UE PDCCH and send to the shared OFDM character position of R-PDCCH of RN, will think that the OFDM allocation of symbols that RN can begin to receive the earliest gives R-PDSCH, be the R-PDSCH Resources allocation.
Carry out the result of resource allocation shown in Fig. 3 A, Fig. 3 B, Fig. 3 C through above-mentioned steps 21.Wherein, a kind of centralized resources mapping schematic diagram of downlink relay link control channel in the resource allocation indicating method of the repeated link that provides for the embodiment of the invention of Fig. 3 A.Among Fig. 3 A, all R-PDSCH are in the relay and control channel band ranges.The another kind of centralized resources mapping schematic diagram of downlink relay link control channel in the resource allocation indicating method of the repeated link that Fig. 3 B provides for the embodiment of the invention.Among Fig. 3 B, the R-PDSCH that has is outside the relay and control channel band ranges.Downlink relay link control channel distributed resource mapping schematic diagram in the resource allocation indicating method of the repeated link that Fig. 3 C provides for the embodiment of the invention.Among Fig. 3 A, Fig. 3 B and Fig. 3 C, 31 is PCFICH, PHICH, the PDCCH from eNB to UE, 32 is PCFICH, PHICH, the PDCCH from RN to UE, 33 is the PDSCH from eNB to UE, 34 is the PDSCH from RN to UE, and 35 is R-PCFICH, R-PHICH, the R-PDCCH from eNB to RN, and 36 receive R-PCFICH, R-PHICH, R-PDCCH, R-PDSCH for RN from eNB, 37 is the R-PDSCH from eNB to RN, and 38 for sending to the transfer zone of reception.
Shown in Fig. 3 A, Fig. 3 B and Fig. 3 C, subframe N is a relay sub-frame.On relay sub-frame, channel conditions and the traffic carrying capacity of eNB by taking all factors into consideration each RN repeated link, can dispose width is BW semi-staticly RFrequency band be used to send downlink relay link control channels such as R-PCFICH, R-PHICH, R-PDCCH.This width is BW RBand resource can shown in Fig. 3 A, Fig. 3 B,, also can be depicted as distributed as Fig. 3 C for centralized.And, for fear of the influence of transmitting-receiving conversion, the primary sign of R-PCFICH, R-PHICH, R-PDCCH is fixed the downlink relay link control channel, promptly work as

The time OFDM sign-on mapping of l=4 in this subframe; When
Figure B2009101747247D0000063
The time OFDM sign-on mapping of l=3 in this subframe.
If the shared frequency resource of R-PDSCH is as shown in Figure 3A, in the shared frequency resource scope of downlink relay link control channel, then with the relay and control channel account for same frequency band R-PDSCH resource mapping primary sign be provided with as shown in table 1.
Table 1
Figure B2009101747247D0000071
At this moment, eNB is that the initial OFDM symbol that distributes of the R-PDSCH of all RN is identical.
If the shared frequency resource of the R-PDSCH of the RN that has is shown in Fig. 3 B, Fig. 3 C, outside the shared frequency resource scope of downlink relay link control channel, then the shared frequency resource of R-PDSCH is provided with as shown in table 2 in the R-PDSCH resource mapping primary sign of the shared extraneous RN of frequency resource of downlink relay link control channel.
Table 2
Figure B2009101747247D0000072
In the above-mentioned steps 22, because RN can't receive the PCFICH of eNB to UE, promptly RN can't know that eNB is to the shared OFDM symbolic number of the PDCCH of UE
Figure B2009101747247D0000081
Then eNB need adopt the initial OFDM symbol of certain message mechanism to RN indication R-PDSCH, such as: the OFDM symbolic number that can described R-PDCCH be taken by one group of source information of R-PCFICH sends to described each RN; Another group source information in described two groups of source information is used for the initial OFDM character position information of described R-PDSCH or described base station are sent to described each RN to the OFDM symbolic number that the PDCCH of UE takies.Perhaps, by OFDM symbolic number that described R-PDCCH is taken and the initial OFDM character position information of described R-PDSCH, or the OFDM symbolic number that takies of described R-PDCCH and described base station send to described each RN to the OFDM symbolic number combined coding that the PDCCH of UE takies in one group of source information of R-PCFICH.Perhaps, by increase DCI form in R-PDCCH or by in the DCI form, increasing bit number, the initial OFDM character position information of described R-PDSCH or described base station are sent to described each RN to the OFDM symbolic number that the PDCCH of UE takies, or by the shared OFDM symbolic number of high-level signaling indication R-PDCCH.
When the initial OFDM character position information of the R-PDSCH that sends as eNB was R-PDSCH with respect to the deviate of the primary sign position of R-PDCCH, the resource allocation methods of the repeated link that the embodiment of the invention provides also can comprise: the OFDM symbolic number that described R-PDCCH is taken sent to described each RN.Like this, each RN just can calculate the initial OFDM symbol that obtains R-PDSCH according to the OFDM symbolic number that deviate and R-PDCCH take.
At this moment, the source information of the R-PCFICH of 4 bits (bit) can be divided into two groups, every group of repeated link control format indication (R-CFI) source information that comprises 2bit, be used to refer to the initial OFDM symbol of shared symbol numbers of R-PDCCH and R-PDSCH respectively, that is, shared OFDM symbol numbers of R-PDCCH and the initial OFDM character position of R-PDSCH information are sent to each RN.Wherein, the initial OFDM character position of R-PDSCH information is the deviate of R-PDSCH with respect to the initial OFDM symbol of R-PDCCH, and the deviate corresponding relation that is used to refer to one group of R-CFI source information of the initial OFDM symbol of R-PDSCH and the initial OFDM symbol of R-PDSCH is as shown in table 3.
Table 3

The method that present embodiment provides is passed through the fixedly initial OFDM symbol of R-PDCCH, make R-PDCCH can not be subjected to transmitting-receiving and transform influence, and can on bigger frequency band, obtain frequency diversity gain, guaranteed the correct reception of repeated link control information, the OFDM symbolic number that takies to the PDCCH of UE as eNB more after a little while, before R-PDSCH is placed on R-PDCCH, made full use of the running time-frequency resource of repeated link.And, during the resource allocation of eNB side, need not to know that RN to the shared OFDM symbolic number of the PDCCH of UE, has saved certain signaling consumption, avoided forward scheduling.Further, initial OFDM character position information by sending R-PDSCH or base station make RN can know the resource allocation information of eNB side, thereby correctly receive the data among the R-PDSCH to the OFDM symbolic number that the PDCCH of UE takies.
The flow chart of the resource allocation indicating method of the another kind of repeated link that Fig. 4 provides for the embodiment of the invention.In the present embodiment, but the shared OFDM symbolic number of PDCCH that each RN prior notice eNB sends toward UE separately.This method comprises:
The shared OFDM symbolic number of PDCCH that step 41, each RN will send toward UE is separately informed eNB in advance, and eNB knows that each RN is to the shared OFDM symbolic number of the PDCCH of UE;
Step 42, eNB according to eNB to UE, RN to UE with the eNB OFDM symbolic number that need take to the control channel of RN
Figure B2009101747247D0000101
These 3 factors decide the initial OFDM symbol of R-PDSCH resource mapping.
It is that the frequency band of BWR is used to send downlink relay link control channels such as R-PCFICH, R-PHICH, R-PDCCH that eNB disposes width semi-staticly.This width is that the band resource of BWR can for centralized, also can be depicted as distributed as Fig. 3 C shown in Fig. 3 A, Fig. 3 B.And, for fear of the influence of transmitting-receiving conversion, the primary sign of R-PCFICH, R-PHICH, R-PDCCH is fixed the downlink relay link control channel, promptly work as The time OFDM sign-on mapping of l=4 in this subframe; When
Figure B2009101747247D0000103
The time OFDM sign-on mapping of l=3 in this subframe.Specifically see the explanation of above-mentioned steps 21 for details.
ENB removes and oneself sends to its PDCCH and the shared OFDM symbolic number of R-PDCCH that oneself sends to RN of UE down, also send to its down shared OFDM symbol numbers of PDCCH of UE according to each RN, the OFDM sign-on that can begin to receive the earliest from each RN is placed the R-PDSCH of each RN.At this moment, the R-PDSCH primary sign of each RN can be different.
If the shared frequency resource of R-PDSCH is as shown in Figure 3A, in the shared frequency resource scope of downlink relay link control channel, then with the downlink relay link control channel account for same frequency band R-PDSCH resource mapping primary sign be provided with as shown in table 4.
Table 4
Figure B2009101747247D0000111
If the shared frequency resource of the R-PDSCH of the RN that has is shown in Fig. 3 C, outside the shared frequency resource scope of downlink relay link control channel, then the out-of-band R-PDSCH resource of the downlink relay link control channel of these RN is shone upon initial OFDM symbol and is provided with as shown in table 5:
Table 5
Figure B2009101747247D0000112
Figure B2009101747247D0000121
If step 43 eNB does not have prior notice RN: the shared OFDM symbolic number of PDCCH that this base station relay sub-frame sends toward UE Then eNB adopts certain message mechanism to indicate the initial OFDM symbol of its R-PDSCH to RN in the relay and control channel.The mode of the initial OFDM symbol of eNB indication R-PDSCH sees the R-PCFICH indicating mechanism in the foregoing description for details.In the present embodiment, the R-CFI source information of R-PCFICH is used to indicate the absolute value of the initial OFDM symbol of R-PDSCH.The initial OFDM symbol corresponding relation of R-CFI source information and R-PDSCH is as shown in table 6.
Table 6
Figure B2009101747247D0000123
If eNB prior notice RN its
Figure B2009101747247D0000124
Then need not to notify the initial OFDM symbol of RN R-PDSCH, RN passes through
Figure B2009101747247D0000125
Can calculate the initial OFDM symbol that obtains R-PDSCH.As according to known
Figure B2009101747247D0000126
Obtain the initial OFDM symbol of R-PDSCH by above-mentioned table 1 or table 2.
The OFDM symbolic number that the method that present embodiment provides takies to the PDCCH of UE by each RN is that the R-PDSCH that eNB arrives each RN distributes the OFDM symbol, avoid receiving and dispatching transform influence in, the accuracy of the R-PDSCH resource allocation that has improved.
A kind of flow chart of knowing the method for shared channel resources assignment information that Fig. 5 provides for the embodiment of the invention.Present embodiment is corresponding with said method embodiment, specifically comprises:
The initial OFDM character position information of step 51, reception R-PDSCH; The OFDM symbolic number that OFDM symbolic number that the initial OFDM character position of described R-PDSCH takies to the PDCCH of UE according to eNB and R-PDCCH take is determined; The initial OFDM symbol of described R-PDSCH is positioned at before or after the OFDM symbol that described R-PDCCH takies; The initial OFDM symbol of described R-PDCCH is fixed;
Step 52, according to the described R-PDSCH of initial OFDM character position message pick-up of described R-PDSCH.
Above-mentioned steps 51, step 52 can be carried out by RN.
In the above-mentioned steps 51, RN receives the initial OFDM character position information of R-PDSCH, and R-PDSCH is with respect to the deviate of the initial OFDM symbol of R-PDCCH as described, or the absolute value of the initial OFDM symbol of described R-PDSCH.
In the above-mentioned steps 52, RN is according to the initial OFDM character position of the initial OFDM character position information acquisition R-PDSCH that receives R-PDSCH.In above-mentioned steps 51, when the information that RN receives is R-PDSCH with respect to the deviate of the initial OFDM symbol of R-PDCCH, shown in above-mentioned table 3, RN can obtain the deviate of R-CFI indication according to table 3, and calculates the initial OFDM symbol of acquisition R-PDSCH according to the OFDM symbolic number that this deviate and R-PDCCH take.In above-mentioned steps 51, when the information that RN receives is the absolute value of initial OFDM symbol of R-PDSCH, as above-mentioned table 6, can be directly obtain the initial OFDM symbol of R-PDSCH from table 6, and receive R-PDSCH from the initial OFDM symbol that obtains according to the information R-CFI that receives.
In the method that present embodiment provides, RN is by receiving the initial OFDM character position information of R-PDSCH, can accurately receive R-PDSCH, and because the initial OFDM symbol that R-PDSCH distributes obtains according to the fixing R-PDCCH of initial OFDM symbol, not influenced by the transmitting-receiving conversion thereby make RN receive R-PDSCH, guaranteed the correct reception of data message.
