Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to a kind of method, Apparatus and system of indexed resource.
Background technology
Long Term Evolution (LTE, Long Term Evolution) with OFDM (OFDM, Orthogonal Frequency Division Multiplexing) be core, the basic thought of OFDM is high-speed data-flow to be distributed on the subcarrier of a plurality of quadratures transmit, thereby the character rate on the subcarrier is reduced greatly, symbol duration extends greatly, thereby expansion has stronger resistance to time delay, has reduced the influence of intersymbol interference.
Physical downlink control channel PDCCH (Packet Dedicated Control Channel) is by control channel unit (CCE, control channel elements) forms, Downlink Control Information (DCI, downlinkcontrol information) is carried on the CCE, in existing scheme, be designated as the particular location of the resource of UE distribution by the DCI bit.The effect of DCI form and each form is as shown in table 1:
Table 1
| The DCI form | Effect |
| DCI form 0 | Be used for uplink scheduling, the resource allocation and the transformat of indication UL-SCH channel |
| DCI form 1 | The descending scheduling that is used for the single antenna port |
| DCI form 1A | The descending scheduling of the single antenna port that is used to compress |
| DCI form 1B | The descending scheduling of single antenna port that is used for the compression of closed loop |
| DCI form 1C | Be used to support paging, RACH response and dynamic dispatching |
| DCI form | |
| 2 | The descending scheduling that is used for downlink closed-loop MIMO is supported the dicode word |
| DCI form 3 | Be used to send TPC order (2bit adjustment) |
| DCI form 3A | Be used to send TPC order (1bit adjustment) |
When using PDCCH, because multiple DCI form is carried on the CCE, promptly be carried on the PDCCH, so at first need 8 kinds of DCI forms correspondences shown in the table 1 are become 4 kinds of forms of PDCCH, 4 kinds of forms of PDCCH are as shown in table 2:
Table 2
| The PDCCH form | The CCE number | The PDCCH number of bits |
| ??0 | ??1 | ??72 |
| ??1 | ??2 | ??144 |
| ??2 | ??4 | ??288 |
| ??3 | ??8 | ??576 |
After the correspondence, for PDCCH, come the indexed resource position by the DCI bit, transmitting terminal is according to the resource location of DCI bit indication, and notice receiving terminal transmitting terminal is the resource location of its distribution, and receiving terminal is according to notifying corresponding resource location to receive data.
The CCE resource of PDCCH is limited, does concrete analysis below.
Because a CCE takies 36 RE, the supposing the system bandwidth is 5M, below the operating position of CCE is analyzed.Under the 5M bandwidth, each OFDM symbol can use 300 RE, if hypothesis has two antennas again, have the 8 groups of automatic request retransmission indicating channel of physical mixed (PHICH, PhysicalHybrid ARQ Indicator Channel), then PHICH takies 24 RE altogether, in addition, Physical Control Format Indicator Channel (PCFICH, Physical Control Format Indicator Channel) takies 16 RE, pilot tone takies 100 RE, and PHICH, PCFICH and pilot tone take 140 RE altogether, and then effective RE of taking of PDCCH is 160 (300-140=160).Because 36 RE form a CCE, so 160 RE can have 4.4 CCE.When more than having obtained 1 OFDM symbol, effective RE number and the CCE number of PDCCH.When under the situation of 2 OFDM symbols, have 600 RE, still use above-mentioned hypothesis, then this moment, the RE number that PDCCH effectively takies is 460, and (300 * 2-140=460) is individual, and the CCE number is 12.78.And the like, be under 3 or 4 s' the situation at the OFDM symbol, all can calculate number and CCE number that PDCCH takies effective RE.Reference table 3, when showing the OFDM symbol and be 1,2,3 and 4, PDCCH takies the number of available RE and the number of CCE.
Table 3
| ??n＝1 | ??n＝2 | ??n＝3 | ??n＝4 | |
| The effective RE number of PDCCH | ??160 | ??460 | ??760 | ??1060 |
| The CCE number | ??4.44 | ??12.78 | ??21.11 | ??29.44 |
Wherein, n is the OFDM symbol numbers.
According to table 3, when the OFDM symbol numbers is 3,, analyze the operating position of 4 kinds of form PDCCH below in conjunction with table 2, table 3.In table 3, when n=3, effective number of CCE is 21.11, and with 21.11 0.11 omit, then effective number of CCE is 21, and based on this, under 4 kinds of forms of PDCCH, the bar number of the PDCCH of every kind of form please refer to table 4.
In the table 4, the implication of second row is: it is 0 PDCCH that 21 wiht strip-lattice types are arranged, owing to during n=3,21 effective CCE are arranged, if all using forms are 0 PDCCH, because every wiht strip-lattice type is 0 PDCCH 1 CCE is arranged, so, have 21 wiht strip-lattice types and be 0 PDCCH.The implication of the third line is: it is that 0 PDCCH and 5 wiht strip-lattice types are 1 PDCCH that 11 wiht strip-lattice types are arranged, if 11 every wiht strip-lattice types of use are 0 PDCCH, then also have 10 effective CCE, for remaining 10 effective CCE, if using form is 1 PDCCH, because every wiht strip-lattice type is 1 PDCCH 2 CCE are arranged, be 1 PDCCH so can use 5 wiht strip-lattice types altogether, so 1 wiht strip-lattice type is that 0 PDCCH and 5 wiht strip-lattice types are that 1 PDCCH has 21 effective CCE.Table 4 following each go, the implication of last column is: it is 0 PDCCH that 1 wiht strip-lattice type is arranged, and 1 wiht strip-lattice type is 2 PDCCH, and 2 wiht strip-lattice types are 3 PDCCH, therefore, have 21 effective CCE.

More than analyzed the number of the spendable effective CCE of PDCCH.Below the shortcoming of PDCCH is analyzed.One skilled in the art will appreciate that generally speaking less data should be used less control information, for example, represent the bit number of control information generally should be less than the bit number of representative data.Under the less situation of data volume,, will make the control information bit number data bit number of comparing seem more if the amount of bits of control information does not correspondingly reduce.Therefore, for some particular services, such as Internet Protocol telephone (VoIP, Voice over Internet Protocol) business, this professional data quantity transmitted is very little, so VoIP is professional when using PDCCH, if also as other large-data operation, use more control information (for PDCCH, be CCE), under the limited condition of CCE number, can cause waste to the CCE resource.Generally speaking, by the particular location of the DCI bit among the PDCCH to the UE indexed resource, having increased the PDCCH signaling consumption in the existing scheme, is a kind of waste to the CCE resource of preciousness.
In addition, the signal that the terminal in the sub-district receives might produce error code in transmission course, therefore, need carry out chnnel coding to the signal of transmission, and to improve efficiency of transmission, the situation that reduces error code takes place.The basic thought of chnnel coding is to insert code element in source traffic, thereby reaches the purpose that receiving terminal is declared wrong and error correction.Be positioned at cell edge if handle the terminal of VoIP business, because communication quality might reduce, more likely in transport process, produce error code, therefore, when carrying out chnnel coding, need to insert more code element, promptly need to insert more bits, if use PDCCH, more bits means the more RE of needs, and in table 4, just probably needing using form is 3 PDCCH, every wiht strip-lattice type is that 3 PDCCH has 8 CCE, and be 3 o'clock in the OFDM symbol numbers, have 21 effective CCE, like this, can will reduce for effective CCE number that other terminal is used, probably influence the communication quality of other terminal.And, be 2 o'clock in the OFDM symbol numbers, this situation is more obvious.

Embodiment
The core of the embodiment of the invention is, adopts not comprise or the PDCCH of the less DCI of comprising bit, avoided prior art problems dexterously, the problem includes: the problem of the CCE that takies preciousness among the PDCCH.
Before describing,, at first introduce the scheduling scheme of VoIP for ease of understanding.The scheduling scheme of the VoIP that LTE determines is a semi-continuous scheduling.The main thought of semi-continuous scheduling is: dynamic dispatching and continuous dispatching are combined.So-called dynamic dispatching, promptly the resource location of Fen Peiing is unfixing, change through regular meeting, so-called continuous dispatching, promptly the resource location of Fen Peiing is more fixing, does not generally change.Process mainly comprises: the opening or closing of semi-continuous scheduling, promptly notify terminal to have semi-continuous scheduling or notice terminal semi-continuous scheduling will finish, if semi-continuous scheduling is for opening, carve at a time, activate semi-continuous scheduling by control channel, the resource location that the notice receiving terminal distributes when receiving expression that receiving terminal returns when having received the message of misdata, uses control channel to notify the resource location of receiving terminal as the misdata distribution again.
VoIP is primarily aimed at four kinds of Packet Services: the initial transmission bag of the initial transmission bag of active period speech (voice) bag, voice retransmission packet, quiet period (SID) bag and SID retransmission packet, semi-continuous scheduling to the processing mode of these four kinds of Packet Services are:
For voice initial transmission bag, predefine resource allocation;
For the voice retransmission packet, adopt dynamic dispatching, but up VoIP retransmission packet also can adopt the mode of predefine resource allocation;
For SID initial transmission bag, adopt dynamic dispatching;
For the SID retransmission packet, adopt dynamic dispatching, but up VoIP retransmission packet also can adopt the mode of predefine resource allocation.
From above semi-continuous scheduling as can be seen, owing to still there is dynamic dispatching, therefore still need control channel to the processing mode of four kinds of VoIP Packet Services.
For realizing goal of the invention, the embodiment of the invention no longer adopts the resource allocation of demonstration, but adopts the resource allocation of hint.The so-called resource allocation that shows, for adopting bit indexed resource position among the PDCCH, the resource allocation of so-called hint is not for adopting bit indexed resource position among the PDCCH.
Please refer to Fig. 1, the method flow diagram for indexed resource of the present invention comprises:
S101: user equipment (UE) is monitored the physical downlink control channel PDCCH of compression, and wherein, the PDCCH of described compression is obtained by the Downlink Control Information DCI correspondence of compressing;
S102: resource number is known in the control information that described UE resolves described PDCCH;
S103: described UE utilizes the resource number of precognition and the corresponding relation of resource location, the resource location of definite resource number correspondence of being known.
Wherein, the resource number of precognition and the corresponding relation of resource location can have two kinds of implementations, first kind of mode is: the base station is when distributing the initial transmission resource for user equipment (UE), by the corresponding relation of high-level signaling notice UE resource number and resource location, the second way is: be the corresponding relation of UE resource allocation numbering with resource location in advance.Hereinafter, be that example describes only in first kind of mode.
And resource number is meant the CCE numbering, and at this moment, UE directly corresponds to resource location according to the numbering of CCE among the PDCCH; Perhaps, resource number is meant the PRB numbering, and at this moment, UE directly corresponds to resource location according to the PRB numbering.Below these two kinds of specific implementations are described in detail.
Embodiment one, and the CCE numbering has been adopted in present embodiment indexed resource position.
At first, the indexed resource position is come by CCE number in the base station, please refer to Fig. 2, total N CCE, be respectively CCE1, CCE2 ..., CCEN, two Physical Resource Block of the numbering 1 arrow indication of CCE1 (PRB, physical resource block), wherein PRB is used for store data, two PRB of the arrow indication of the numbering 2 indication CCE2 of CCE2, two PRB of the arrow indication of the numbering N indication CCEN of CCEN.
Each CCE has indicated two PRB in the present embodiment, this is a kind of scheme, can also comprise other scheme certainly, such as, each PRB of CCE indication or more PRB, perhaps, can also make each CCE indicate the PRB of different numbers, for example, CCE1 indicates 1 PRB, CCE2 indicates 3 PRB, and CCE3 indicates 3 PRB, or the like.
Adopt CCE numbering indexed resource position, the process number of re-transmission can be determined by previous transmission pointer (PTR, previous transmission pointer).Please refer to Fig. 3, PTR=5 represents that the packet of the head indication of arrow 1 is the re-transmission of packet of the afterbody indication of arrow 1, and PTR=8 represents that the packet of the head indication of arrow 2 is re-transmissions of packet of the afterbody indication of arrow 2.Like this, the HARQ process number of re-transmission just can have been determined.
Owing to use CCE indexed resource position, the bit number of DCI will significantly reduce, and for the bit number that DCI is described better significantly reduces, provides the bit number of each control information of prior art DCI earlier, for the various forms of DCI, be that example describes only with DCI form 1.Please refer to table 5,
Table 5
| The control information territory | Existing DCI form 1 bit number |
| Distributed transmission sign (Distributed transmission flag) | 1 (indicating whether to use distributed) |
| Resource allocation head (Resource allocation header) | 1 (type0 or type1) |
| Resource block assignments (RB allocation) | ??25 |
| Modulating-coding grade (MCS) | ??5 |
| Mixed automatic retransmission request process number (Hybrid ARQ process number) | 3 or 4 |
| New data indication (New data indicator) | ??1 |
| Redundancy versions (Redundancy version) | ??2 |
| Power control commands word TPC | ??2 |
| Radio Network Temporary Identifier/check digit (RNTI/CRC) | ??16 |
| Total bit number | 56 or 57 |
When adopting CCE indexed resource position, in the table 5, the control information relevant with resource allocation in control information territory and some other control informations just can no longer need, its bit number will become 0, these control informations have: Distributed transmission flag, Resource allocation header, RBallocation, MCS, New data indicator.For convenience of description, the DCI form 1 that bit number is reduced calls the DCI of compression.
See also table 6, provided employing CCE indexed resource position, the bit number of each control information of the DCI of compression and the contrast of unpressed DCI,
Table 6
| The control information territory | Unpressed DCI bit number | The DCI bit number of compression |
| ??Distributed?transmission?flag | 1 | ??0 |
| ??Resource?allocation?header | 1 | ??0 |
| ??RB?allocation | 25 | ??0 |
| ?? |

| ??New?data?indicator | 1 | ??0 |
| ??Redundancy? |
2 | ??2 |
| ?? |
2 | ??2 |
| ??RNTI/CRC | 16 | ??16 |
| Total bit number | 56 or 57 | 23 or 24 |
As can be seen from Table 6, the bit number of DCI form 1 is reduced to 23 or 24 from original 56, perhaps, is reduced to 23 or 24 from original 57, at this, is that example describes to be reduced to 23 or 24 from 56 only.23/56=0.410,24/56=0.428, as seen, adopt CCE indexed resource position, the bit number of DCI form 1 nearly reduces half, bit number reduces, the symbol quantity of the OFDM that is modulated into will reduce, and then sign map is that the quantity of RE also can reduce, because CCE is made up of RE, RE reduces, and the CCE number also can reduce naturally.Because PDCCH is made up of CCE,,, the PDCCH of CCE number minimizing is called the PDCCH of compression at this for ease of describing.
It more than is exactly the bit number situation of each control information of the DCI of compression provided by the invention.During semi-continuous scheduling, just can use the PDCCH of compression provided by the invention.
Referring to Fig. 4, be embodiment one flow chart, comprising:
S401: the opening of terminal semi-continuous scheduling (promptly notify terminal to have semi-continuous scheduling, but uncertain when the beginning), duration are informed by high-level signaling in the base station, simultaneously the CCE number corresponding relation with resource location are notified to terminal.
S402: the base station adopts the DCI of compression provided by the invention to activate semi-continuous scheduling.
Activate the DCI notice terminal resource position that semi-continuous scheduling promptly uses compression for the first time herein.
S403: terminal receives data at the resource location of PDCCH appointment, if the data that receive do not have mistake, terminal is returned ACK message, makes a mistake in case detect the data that receive, and terminal is returned NACK message.
S404: NACK message is received in the base station, and the data that mistake occurs are retransmitted.
Need to prove, behind the base station activation semi-continuous scheduling, the short of NACK message that receives, just do not re-use the PDCCH notice terminal resource position of compression, and still new data is sent to the resource location of the PDCCH appointment of compression when activating, the resource location that terminal is learnt when activating receives data and gets final product, in case the base station receives NACK message, learn to retransmit some data, then use the resource location of the PDCCH notice terminal re-sends data of compression provided by the invention.
S405: terminal receives data retransmission to the resource location of data retransmission.
For non-data retransmission, the resource location that terminal is still learnt when activating receives data.
S406: the base station is by the pass (being that semi-continuous scheduling closes to an end) of high-level signaling notice terminal semi-continuous scheduling.
Embodiment two, are that with the difference of embodiment one two pairs of PRB Resource Block of embodiment number the indexed resource position, and the CCE of PDCCH and PRB have mapping relations.
Please refer to Fig. 5, show PRB block number indexed resource position.In advance the resource that sends is carried out the resource group # soon, every group of PRB distributed a PRB numbering, as No. 1 PRB group among Fig. 5, No. 2 PRB groups, No. 3 PRB groups.
Adopt PRB numbering indexed resource position, each the control information bit number of the DCI of compression and the contrast of unpressed DCI are as shown in table 7,
