Description
Technical field
The present invention relates to the method for in wireless communication system, information being encoded, perhaps more specifically to the method to encoding about the information of the first kind in wireless communication system or Equations of The Second Kind component carrier.The invention still further relates to method in transmission node and the method in receiving node, and transmission node wherein and receiving node.
Background technology
In wireless communication system, increasing system bandwidth is to improve a kind of method of systematic function (as peak data rate, throughput of system, capacity etc.).Although some advanced techniques such as multiple-input and multiple-output (MIMO), high order modulation and mixed automatic retransmission request (HARQ) can be used for the performance of further enhancing system aspect spectrum efficiency, system bandwidth remains the bottleneck that improves systematic function.Equally, be International Telecommunications Union (ITU) requirement of satisfying senior international mobile telecommunication (IMT), wireless communication system will must be able to be supported the bandwidth larger than existing bandwidth.
In Long Term Evolution (LTE) version-8 (Rel-8) communication system, the maximum system bandwidth of support can satisfy the requirement of descending/up (DL/UL) 100Mbs/50Mbps peak data rate up to 20MHz.Senior LTE (LTE-A) communication system (3GPP TR 36.913 v8.0.1) will become the innovation of LTE Rel-8 system, require to provide the system bandwidth up to 100MHz, thereby divide the peak data rate that obtains 1Gbps/500Mbps for DL/UL.
In order to obtain wider system bandwidth in LTE-A, must consider a plurality of component carriers of polymerization, corresponding operation is called as carrier aggregation.The component carrier of polymerization can be arranged in one or more frequency bands with connected or non-connected frequency.In LTE, only use the one-component carrier wave, this component carrier is the phase continuous frequency band spectrum in a certain bandwidth.
The important requirement of LTE-A system is the problem of backwards compatibility, this means that in the case LTE Rel-8 subscriber equipment (UE) should be able to work in the LTE-A communication system, that is, the LTE-A communication system should be transparent for LTE Rel-8UE.
In LTE Rel-8 system, supported system bandwidth pattern comprises 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz and 20MHz, and other carrier aggregation are not subjected to the support of LTE Rel-8 standard.In order to make the LTE-A system that adopts carrier aggregation can back compatible LTE Rel-8UE, have at least the component carrier of (preferably an each) polymerization can enter LTE Rel-8UE in the LTE-A system.Fig. 1 has shown the example that has the LTE-A system bandwidth of 100MHz by 5 connected 20MHz LTE Rel-8 component carriers of polymerization.
In the LTE-A system, imagine asymmetric carrier aggregation with supported, this means that the quantity of the component carrier in DL and UL is with difference.Usually, many than in UL of the polymerization component carrier in DL.This can should be used for promoting by precognition, this means that the DL traffic load is usually high than UL traffic load.For the consideration that reduces UE transmitter complexity, it also is fit to utilize quite few upstream components carrier wave very much.
In the LTE-A system, be not precluded between DL and UL component carrier and different bandwidth polymerization with varying number.For example, can be in DL the component carrier of two 20MHz of polymerization, and only use the component carrier of a 20MHz in UL, this example as shown in Figure 2.
For the relation between the DL carrier wave in LTE Rel-8UL and Frequency Division Duplexing (FDD) (FDD), a fixing acquiescence UETX-RX(transceiver is arranged) the centre carrier frequency interval, that is, the distance between DL centre carrier frequency and UL centre carrier frequency is fixed.In other words, the UL of LTE Rel-8UE identification and DL carrier wave should be by fixing default interval pairings.In Fig. 2, only have one of them DL component carrier and UL carrier wave to have fixing default interval, so LTE Rel-8UE can only work on this a pair of carrier wave.But for other DL carrier waves, in Fig. 2, LTE Rel-8UE can't access this component carrier, because there is no corresponding UL carrier wave.Therefore, this component carrier can not backward compatibility LTE Rel-8UE.
LTE Rel-8UE can not access the carrier wave of non-back compatible, and simultaneously, LTE-A UE can not identify and access this type of carrier wave.Therefore be difficult to stop the non-back compatible carrier wave of LTE Rel-8UE access, and support simultaneously LTE-A UE to work on backward compatibility and non-backward compatible carrier waves.
According to the prior art solution of suggestion, can carry out some changes to synchronous and/or reference signal sequence on non-back compatible carrier wave, make LTE Rel-8UE detect these carrier waves fully.This solution is hinting that backward compatibility carrier wave and non-backward compatibility carrier wave should use different synchronizing signals and/or reference signal sequence, and is hinting that further synchronizing signal or reference signal on non-backward compatibility carrier wave can't be identified by LTE Rel-8UE.Make in this way, LTE Rel-8UE can't access these non-backward compatibility carrier waves.
Yet the shortcoming of this suggested solution is the complexity that can increase eNodeB and LTE-A UE, because must generate or detect a plurality of synchronizing signals.Will stop like this solution of (for example) economical and efficient to be adopted as to realize the synchronous and popular chip of exploitation of Rel-8.To change the introducing synchronizing signal according to suggestion and also mean the complexity that needs is increased communication system architecture.

Accompanying drawing is intended to illustrate and explain the present invention, wherein:
Fig. 1 for example understands the connected carrier aggregation in wireless communication system, thereby obtains wider system bandwidth; And
Fig. 2 for example understands the asymmetric carrier aggregation in wireless communication system.
Embodiment
As described herein, the LTE-A communication system is considered to the innovation of LTE Rel-8 system.This paper also mentions, to obtain for DL/UL the peak data rate of 1Gbps/500Mbps, system bandwidth up to 100MHz must be provided, realize that this system bandwidth can adopt above-mentioned carrier aggregation technology, wherein component carrier is aggregated in single polymerization carrier wave in continuous or discrete mode.The LTE-A communication system also requires it should have back compatible, for example, and back compatible LTE Rel-8UE.
In addition, the new technical feature as to the senior version of LTE (for example, high-order mimo, cooperative multipoint transmission, relaying etc.) expectation may need to be thought of as these new transmission technologys non-back compatible carrier wave is optimized comprehensively.This type of carrier wave not necessarily will be subjected to the restriction of reference signal, transmission mode and feedback mechanism in LTE Rel-8 system, so Rel-8UE can not access these carrier waves.
Simultaneously, in order to simplify wireless communication system, the transmission structure difference between back compatible carrier wave (being applicable to LTE-A UE and LTE UE) and non-back compatible carrier wave (being only applicable to LTE-A UE) is preferably as far as possible little.Otherwise (for example) eNB need to be equipped with two groups of different emitter/receiver structures with non-back compatible carrier wave for the back compatible carrier wave with LTE-A UE, this means complexity and the cost that will increase constructing system.
On the back compatible carrier wave, in the search of initial zone flow process, at first UE uses synchronizing signal (comprising master sync signal and auxiliary synchronous signals) to come synchronizeing of acquisition time and frequency and residential quarter and residential quarter ID.UE can detect Physical Broadcast Channel (PBCH) to obtain basic system information (as system bandwidth, antenna port quantity etc.) afterwards.After obtaining these information, UE can detect other physical signallings, and sets up uplink synchronous.
According to the present invention, can not detect non-back compatible carrier wave in order to make LTE Rel-8UE, can block LTE Rel-8UE in the search of initial zone flow process, to avoid receiving the fundamental system information of non-back compatible carrier wave.Other transmission structures such as Physical Downlink Shared Channel (PDSCH), Physical Downlink Control Channel (PDCCH) also can similar or same system and the emitter/receiver structure that is used for simplifying eNB and LTE-A UE.
The present invention by a kind of in wireless communication system to about first or the information of the Equations of The Second Kind component carrier method of encoding solved the problems referred to above.According to the present invention, the corresponding back compatible carrier wave of first kind carrier wave, the corresponding non-back compatible carrier wave of Equations of The Second Kind carrier wave this means that LTE Rel-8UE can access first kind carrier wave, but can not access the Equations of The Second Kind carrier wave.The method comprises for carrying out scrambler at cyclic redundancy check (CRC) (CRC) bit of the transmission block of the channel of each first kind component carrier processes (the first set that the sequence of use belongs to sequence), and/or process (the second set that the sequence of use belongs to sequence) for carrying out scrambler at the CRC bit of the transmission block of the channel of each Equations of The Second Kind component carrier, and the sequence that wherein belongs to sequence the second set is different from the sequence that belongs to sequence the first set.That is, first of sequence the set does not have common element with the second set.Simultaneously, on each component carrier, has the physical channel of a transmission at least, as PBCH, PDCCH or PDSCH.
According to one embodiment of present invention, the problem of blocking non-back compatible carrier wave for LTE Re-8UE can be solved by revising PBCH, and the method can prevent that LTE Rel-8UE from detecting described signal, but this signal can be detected by LTE-A UE.On the back compatible carrier wave, the PBCH transmission structure will be explained hereinafter.
At first, the whole transmission block a of PBCH

L-1, wherein, A is the transmission block size, that is, the quantity of information bit, L is the quantity of CRC Parity Check Bits, is made as 16.Secondly, the CRC Parity Check Bits is 16 by a length
Sequence (CRC mask) carry out scrambler and process, the transmitting antenna of a certain quantity of the corresponding eNB configuration of this sequence, n=1 wherein, 2 or 4.After scrambler was processed, mask CRC Parity Check Bits was c

I=0,1 ..., 15.Mapping relations between three scrambler sequence and antenna port quantity are as shown in table 1.
The CRC mask of table 1:PBCH

| 1 | <0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0> |
| 2 | <1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1> |
| 4 | <0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1> |
Afterwards, mask CRC Parity Check Bits will append to the transmission block of PBCH, to obtain some bits, as a
0, a
1... a
A-1, c
0, c
1..., c
15Afterwards, all information bits (comprising BCH transmission block and CRC bit) all will be through processing such as chnnel coding, rate-matched, modulation, antenna mapping and transmissions.At receiver end, the blind spot that UE carries out PBCH detects, and this means that UE which mask in three CRC masks of test will cause to be correctly decoded.
Except in LTE Rel-8 system when first three CRC mask (these masks can be used for defining sequence first of the present invention and gather), the present invention also comprises introduction sequence second set of at least one extra CRC mask, to indicate existing of non-back compatible carrier wave.When launching PBCH on non-back compatible carrier wave, application is belonged to one of them extra CRC mask of sequence the second set.Three sequences can only identification table 1 listing due to LTE Rel-8UE are also carried out blind spot with these three candidate sequences and are detected, if therefore the CRC bit carries out the scrambler processing by these extra CRC masks, LTERel-8UE can not correctly detect PBCH.Therefore, they will can not detect PBCH, and can't access corresponding component carrier.
On the other hand, LTE-A UE understands the situation that exists of original CRC mask and newly-increased CRC mask.When LTE-A UE detects PBCH, it will be under the assumed condition of the transmitting antenna of varying number demodulation PBCH, carry out rate de-matching and decoding, then test each possible CRC mask hypothesis, understand which mask and can detect by CRC.If the CRC mask that has detected is not any one in three masks that define in LTE Rel-8 system, LTE-A UE will suppose that it is non-back compatible carrier wave, otherwise be assumed to the back compatible carrier wave.
Minimum Hamming distance between CRC mask in table 1 is 8, and the CRC mask of extra definition preferably should have the Hamming distance of beating as far as possible, is the possibility of back compatible carrier wave in order at utmost reduce LTE Rel-8UE with non-back compatible carrier wave wrong identification.For example, some can to keep minimum Hamming distance be that 8 extra CRC mask comprises:
<1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0>,<1,1,1,1,1,1,1,1,0,0,0,0,0,0,0,0>,<0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,1>,<1,1,1,1,0,0,0,0,1,1,1,1,0,0,0,0>,<0,0,0,0,1,1,1,1,0,0,0,0,1,1,1,1>,<1,1,1,1,0,0,0,0,0,0,0,0,1,1,1,1>,<0,0,0,0,1,1,1,1,1,1,1,1,0,0,0,0>.
According to the present invention, need in sequence second set at least one extra CRC mask to identify non-back compatible carrier wave.But, also can define a plurality of different CRC masks and be used for other information (for example, antenna port quantity etc.) are implied coding.For example, on a non-back compatible carrier wave, may exist:
● one group of LTE-A antenna port,
● one group of LTE Rel-8 antenna port, or
● one group of LTE-A and LTE Rel-8 antenna port,
Wherein LTE Rel-8 antenna port is defined according to LTE Rel-8 standard by public reference signal (CRS), and the LTE-A antenna port is defined according to the LTE-A standard by channel condition information reference information (CSI-RS).At eNB or via node one end, for each component carrier configures several LTE Rel-8 antenna ports and/or LTE-A antenna port.
Therefore, can use extra CRC mask that the relevant information of above combination is encoded.Namely, use certain mask can also indicate some Rel-8 antenna ports on non-back compatible carrier wave and/or the some LTE-A antenna ports on non-back compatible carrier wave, this means and use the coded message content of the sequence in sequence the second set may relate to more information in one embodiment.
In LTE Rel-8, may launch PBCH with one, two or four antenna port, and the CRC bit carries out scrambler by corresponding mask and processes.For diversity, space frequency block coding (SFBC) is applicable to two antenna ports, and the space frequency block coding frequency is switched emission (SFBC+FSTD) and is applicable to four antenna ports.In LTE-A, use four antenna ports just to be enough to carry out the PBCH emission, although more antenna ports can be supported in the residential quarter.The antenna port of PBCH can be from LTE Rel-8, or is the antenna port of the new definition of LTE-A system.Therefore, contingent situation is in the LTE-A system, and the antenna port that is used for emission PBCH is less than the available port (for example, 8 antenna ports) of specific cell.This means in order to form contrast with LTE Rel-8 system, we can consider to allow the CRC mask quantity that the some antenna ports of carrier wave are encoded be different from (greater than) be used for the antenna port quantity of emission PBCH.
The quantity that is used for the antenna port of emission PBCH can be fixed, and can be also configurable.If antenna port quantity is fixed as two antenna ports, this will mean that non-back compatible carrier wave must support at least two antenna ports all the time.Therefore, when using PBCH, the embodiment of the present invention contains following instance for non-back compatible carrier wave:
● the antenna port quantity of PBCH is fixed,
01 groups of LTE Rel-8 antenna ports are used for the PBCH emission
01 groups of LTE-A antenna ports are used for the PBCH emission
● the antenna port quantity of PBCH is configurable,
01 groups of LTE Rel-8 antenna ports are used for the PBCH emission
01 groups of LTE-A antenna ports are used for the PBCH emission
In order to set forth the present invention more thoroughly, we will introduce the unrestricted model embodiment of the present invention in different instances.
Example 1
Several transmitting antennas that are used for emission PBCH on non-back compatible carrier wave are (for example, the predefine) of fixing.For example, on each non-back compatible carrier wave, PBCH uses (two, four or eight a) transmitting antenna to launch all the time.New CRC mask only is used to indicate non-back compatible carrier wave.Therefore need the next signal to carrier wave transmitting antenna port arrangement of extra signaling.
Model embodiment 1:
Configuration mode is only have (two or four) LTE Rel-8 antenna port on each non-back compatible carrier wave, and PBCH to launch with LTE Rel-8 antenna port.In this example, only introduce a new CRC mask and be used to indicate non-back compatible carrier wave.If consider three CRC masks of current LTE Rel-8, PBCH will have four CRC masks altogether so, and will be as shown in table 2.
The CRC mask of table 2:LTE-A PBCH
Model embodiment 2:
Configuration mode is, the PBCH on each non-back compatible carrier wave launches with the LTE-A antenna port of fixed qty, and this antenna port quantity is default value.For example, default value can be 1(2,4 or 8), this means that PBCH is at 1(2,4 or 8) launch on individual LTE-A antenna port.The CRC mask configuration of LTE-A PBCH is as shown in table 3.
The CRC mask of table 3:LTE-A PBCH
Example 2
The quantity that is used for the transmitting antenna of emission PBCH on non-back compatible carrier wave is fixed.The new CRC mask of introducing is used to indicate the antenna port of non-back compatible carrier wave and several configurations.This is similar with the embodiment 1 and 2 with extra CRC mask.
Model embodiment 3:
Only configure 1(2 or 4 on non-back compatible carrier wave) individual LTE Rel-8 antenna port, and PBCH launches (perhaps according to embodiment 2, PBCH launches) on the LTE-A of fixed qty antenna port on these ports.New CRC mask is used to indicate the quantity of non-back compatible carrier wave and LTE-A antenna port.For example, the quantity of LTE-A antenna port can be 1,2,4 or 8, and will introduce 4 extra CRC masks and be used to indicate, and is as shown in table 4.
The CRC mask of table 4:LTE-A PBCH
Example 3
PBCH transmission structure on non-back compatible carrier wave is relevant to the configuration quantity of transmitting antenna port.For example, when two and four transmitting antennas are arranged, use respectively SFBC and SFBC+FSTD to carry out the PBCH emission.For this example, new CRC mask need to be identified the quantity of non-back compatible carrier wave and transmitting antenna port.
Model embodiment 4:
LTE Rel-8 antenna port quantity on non-back compatible carrier wave can be 1,2 or 4, and PBCH launches having on the LTE Rel-8 antenna port of respective transmissions structure.When only having 1 LTE Rel-8 antenna port on non-back compatible carrier wave, PBCH launches with normal mode; When 2 and 4 LTE Rel-8 antenna ports are arranged, PBCH will be respectively with the form emission of SFBC and SFBC+FSTD.Can observe PBCH and have identical transmission structure as on the back compatible carrier wave.In this example, the new extra CRC mask of introducing should be identified the quantity of the LTE Rel-8 antenna port of non-back compatible carrier wave and configuration.
The CRC mask of table 5:LTE-A PBCH
Model embodiment 5:
Unique difference of comparing with embodiment 4 is, the quantity of the LTE Rel-8 antenna port that configures on non-back compatible carrier wave is 1 or 2, and the CRC mask of introducing two correspondences is used to indicate the quantity of the LTE Rel-8 antenna port of non-back compatible carrier wave and configuration.
The CRC mask of table 6:LTE-A PBCH
Model embodiment 6:
On non-back compatible carrier wave, PBCH launches on the LTE-A antenna port, and the quantity of the LTE-A antenna port of configuration can be 1,2,4 or 8.Use 4 extra CRC mask non-back compatible carrier waves of identification and the quantity of LTE-A antenna port.
The CRC mask of table 7:LTE-A PBCH
In the LTE-A system, can consider the possible scheme that adopts relaying to be used as the Extended Cell coverage and improve cell-edge performance (as spectrum efficiency).If introduce via node in system, the standard traffic between eNB and UE, also will there be private communication between LTE-A eNB and via node.Therefore, need some private resource to realize information exchange between LTE-A eNB and via node, herein " special use " refer to the resource that UE can't use.
Non-back compatible carrier wave can also be used for communicating by letter between LTE-A eNB and via node.When this communication occured, LTE Rel-8UE can not access these configurations with LTE-A UE and be used for realizing the carrier wave that eNB communicates by letter with via node, and this carrier-specific transmits in the backhaul of via node.In order to stop that all UE access this type of carrier wave, a kind of special CRC mask that can't be identified by UE or use can be used for PBCH, the PBCH that namely is exclusively used on the carrier wave that the via node backhaul transmits can use special via node CRC mask.
