In a kind of design, can in the FL control section in each PHY frame, send these control channels.The FL control section can comprise enough stock numbers, and for example, enough tile numbers are to carry the control information of all control channels.

Fig. 4 shows the design of FL control section 400.In this design, the FL control section comprises that common segment and zero or index are more a plurality of (K) link assignment piece (LAB) section of 0 to K-1.In the following description, word " index is the element of x " and " element x " are used interchangeably, and wherein element can refer to any amount.Common segment can comprise that index is 0 to L the FLCS tile of L-1, wherein L >=1 and can be configurable value.The FLCS tile is the tile that is used to the FL control section.K LAB section can comprise 3K FLCS tile, and each LAB section comprises three continuous FLCS tiles, as shown in Figure 4.Also can otherwise define the FL control section.In a kind of design, common segment carry in the table 1 maybe be except that F-SCCH all control channels.If there is the LAB section, then F-SCCH can send in K LAB section, otherwise can in common segment, send.

In a kind of design, common segment can be divided into N _FLCSIndividual FLCS resource, wherein N _FLCSCan exist with ... the number of the FLCS tile that is used for common segment and other possible factors.The FLCS resource is to simplify the logical resource of the distribution and the use of common segment.The FLCS resource can map to the transmission unit in the common segment in every way.Resource mapping can make common segment can realize following one or more:

Scalability-regardless of the number of FLCS tile, the mapping of the transmission unit in FLCS resource to L the FLCS tile all should be easy to convergent-divergent,

Divide collection-each FLCS resource can be mapped to the branch collection of a plurality of transmission units with realization FLCS resource,

S the FLCS resource that symmetrical mapping-L is continuous be integrated into another position that moves to the FLCS tile before can be mapped to L the same position in the continuous FLCS tile, S >=1 wherein,

The set of localization mapping-many FLCS resource can be mapped to FLCS interior adjoin transmission unit observing similar channel response,

Distributed mapping-the FLCS resource can be mapped to different FLCS tiles with observation randomization channel response continuously, and

Forbidding area-FLCS resource can be mapped to the available transmission unit, and avoids being mapped to the intrazonal unavailable transmission unit of forbidding.

Can be as follows reach above characteristic with describing.

In a kind of design, can obtain three diversity orders through three transmission units that each FLCS resource mapped at the most in three different FLCS tiles.Also can obtain other diversity orders (for example, 2,4 etc.) through the transmission unit that each FLCS resource is mapped to different numbers.For the purpose of clear, the major part supposition FLCS resource of below describing is mapped to and obtains three diversity orders.

In a FLCS resource mapping scheme, the FLCS resource is mapped to the transmission unit in the common segment with the mode of reaching scalability, three diversity orders and localization mapping.The one FLCS resource mapping scheme also can be called as piece channel resource (BRCH) mapping scheme.

For a FLCS resource mapping scheme, that kind that each FLCS tile can be as shown in Figure 3, and can comprise 110 transmission units that can be used for sending control information.If common segment comprises L FLCS tile as shown in Figure 4, the sum that then is used for the FLCS resource of common segment can be given as:

formula (1)

Wherein

expression rounds (floor) operator downwards.N _FLCSIndividual FLCS resource can be assigned 0 to N _FLCS-1 index.

Fig. 5 shows the design of the FLCS tile of three diversity orders that can be used for supporting a FLCS resource mapping scheme.In this design, the FLCS tile is divided into three tile sections 0,1 and 2.Each tile section comprises 36 transmission units that the FLCS resource can be mapped to.36 transmission units in each tile section can be assigned index 0 to 35 based on predetermined mapping.In the design shown in Fig. 5; Transmission unit 0 in time period 0 occupies the hop-ports 2 in the OFDM code-element period 0; Transmission unit 0 in time period 1 occupies the hop-ports 4 in the OFDM code-element period 6, and the transmission unit 0 in the time period 2 occupies the hop-ports 6 in the OFDM code-element period 0.Other 35 transmission units in each time period have been shown among Fig. 5.

Fig. 6 shows the mapping in order to FLCS resource to three transmission unit of three diversity orders of reaching a FLCS resource mapping scheme.In this design, index is that the FLCS resource of R is mapped to three transmission units that index in all three tile sections 0,1 and 2 of three continuous FLCS tiles at the most is all r.Map unit 610 can receive the index R of FLCS resource and can confirm that (i) is used for the index h and the (ii) index r of the transmission unit that is mapped to of FLCS resource of a FLCS tile of FLCS resource.FLCS resource R can be mapped to the transmission unit r in the tile section 2 of transmission unit r and FLCS tile h+2 of tile section 1 of transmission unit r in the tile section 0 of FLCS tile h, FLCS tile h+1 subsequently.For the purpose of clear, Fig. 6 shows three continuous FLCS tiles that are used to FLCS resource R.Three FLCS tiles also can be reeled like following description ground.

In the design shown in Fig. 6, when L >=3, three diversity orders are to reach through three transmission units that the FLCS resource mapped in three different FLCS tiles.In addition, the FLCS resource is mapped to three different tile sections in three FLCS tiles, and occupies the different time-frequencies position in three FLCS tiles thus.FLCS may observe frequency diversity (owing to mapping to three different hop-ports) and time diversity (owing to mapping to different OFDM code elements).

Regardless of the number of the FLCS tile that is used for common segment, the design shown in Fig. 6 all can be reached three diversity orders.If L=1, then the FLCS resource is mapped to three transmission units in three tile sections 0,1 and 2 of a FLCS tile.If L=2, then the FLCS resource be mapped to a FLCS tile tile section 0 and 2 and the tile section 1 of another FLCS tile in three transmission units.If L >=3, then the FLCS resource is mapped to three transmission units in the tile section 0,1 and 2 of three FLCS tiles.

In a kind of design, localization mapping can be trooped and reaches through four continuous FLCS resources being mapped to 2 * 2 of four transmission units.Look back Fig. 5; Four of can be mapped in three tile sections of four continuous FLCS resources adjoin transmission unit 0 to 3; Four of can be mapped in three tile sections of following four continuous FLCS resources adjoin transmission unit 4 to 7, and four of can be mapped in three tile sections of following again four continuous FLCS resources adjoin transmission unit 8 to 11 or the like.It is static relatively that radio channel response can be presumed to be on the trooping of per four transmission units.The value of control channel can be sent in four continuous FLCS resources, and can be mapped to each tile Duan Zhongsi subsequently and adjoin trooping of transmission unit.This value will be observed each constant relatively channel response of trooping subsequently, and this can promote demodulation performance.Transmission unit 32 to 35 is 1 * 2 modes of trooping, so that utilize all the other transmission units in the FLCS tile.Localization mapping also can be corresponding to other cluster size and shape---for example 2 * 3 troop, 3 * 3 troop etc.---carries out.

Fig. 7 also shows the mapping of each four FLCS resource collection of a corresponding FLCS resource mapping scheme to transmission unit.For each FLCS tile; Formula (3) maps to transmission unit 0 to 3 with the one or four FLCS resource collection in the FLCS tile; The two or four FLCS resource collection is mapped to transmission unit 4 to 7, and last four FLCS resource collections are mapped to transmission unit 32 to 35 (not shown in Fig. 7).

It is h that each FLCS resource is mapped to index ₀, h ₁And h ₂Three tile sections 0,1 and 2 of three different FLCS tiles at the most of---it is suc as formula such calculating shown in (4)---.h ₀Equal the initial FLCS tile index h that formula (2) is provided.h ₁And h ₂Corresponding to following two FLCS tiles, these two index possibly reel back 0 because of mod L calculates after reaching L-1.If L=2, then h ₂Can equal h, and if L=1, then h ₁And h ₂Can equal h.

Each FLCS resource is mapped to three transmission units that have same index r in three tile sections 0,1 and 2.For each tile section k---wherein k ∈ 0,1,2}, function F _P ^k() provides the hop-ports p of transmission unit r _k, and function F _S ^k() provides the OFDM code-element period t of transmission unit r _kFunction F corresponding to tile section 0 _P ⁰() and F _S ⁰() can be confirmed the function F of corresponding tile section 1 according to the left tile fragment among Fig. 5 _P ¹() and F _S ¹() can be confirmed according to middle tile section, and the function F of corresponding tile section 2 _P ²() and F _S ²() can be confirmed according to the right tile fragment.For design described above, FLCS resource R is mapped to (i) FLCS tile h ₀The OFDM code-element period t of middle tile section 0 ₀In hop-ports p ₀On transmission unit r, (ii) FLCS tile h ₁The OFDM code-element period t of middle tile section 1 ₁In hop-ports p ₁On transmission unit r and (iii) FLCS tile h ₂The OFDM code-element period t of middle tile section 2 ₂In hop-ports p ₂On transmission unit r.

In the 2nd FLCS resource mapping scheme, the mode that the FLCS resource can be reached scalability, three diversity orders and avoid forbidding the area is mapped to the transmission unit in the common segment.The 2nd FLCS resource mapping scheme also can be called as distributed resource channel (DRCH) mapping scheme.

Fig. 8 shows the design of the FLCS tile that can be used for the 2nd FLCS resource mapping scheme.In this design, drop in the forbidding area and the transmission unit that is not useable for the FLCS resource is marked as " X ".Unavailable transmission unit can be used for such as channels such as forward direction CPICH Common Pilot Channel, forward direction beacon pilot frequency channels.Not can be used for the FLCS resource at the intrazonal transmission unit of forbidding.The number N of available transmission unit _AVAILExist with ... the sum of transmission unit in the FLCS tile and the number of unavailable transmission unit.The available transmission unit can be assigned the uniqueness index, and this index starts from 0 corresponding to transmission unit in the lower left corner of FLCS tile and with N _AVAIL-1 finishes corresponding to the transmission unit in the upper right corner.In the example shown in Fig. 8, the FLCS tile comprises that 38 unavailable transmission units and index are 90 available transmission unit of 0 to 89.

For the 2nd FLCS resource mapping scheme, the sum of the FLCS resource of common segment can be given as:

formula (5)

N _FLCSIndividual FLCS resource can be assigned 0 to N _FLCS-1 index.The number M of the FLCS resource of every FLCS tile can be given as:

formula (6)

Fig. 9 shows the mapping in order to FLCS resource to three transmission unit of three diversity orders of reaching the 2nd FLCS resource mapping scheme.In this design, index is that the FLCS resource of R is mapped at the most three transmission units in three continuous FLCS tiles.Map unit 910 can receive the index R of FLCS resource and can confirm that (i) is used for the index h and the (ii) index r of the transmission unit that is mapped to of a FLCS tile FLCS resource of a FLCS tile of FLCS resource.FLCS resource R can be mapped to transmission unit r, the transmission unit r+M among the FLCS tile h+1 and the transmission unit r+2M among the FLCS tile h+2 among the FLCS tile h subsequently.For the purpose of clear, Fig. 9 shows three continuous FLCS tiles that are used for FLCS resource R.Three FLCS tiles also can be reeled like following description ground.

In the design shown in Fig. 9, when L >=3, three diversity orders are to reach through three different transmission units that the FLCS resource mapped in three different FLCS tiles.When one or two FLCS tile is used to common segment, also can reach three diversity orders.

For the 2nd FLCS resource mapping scheme, FLCS resource R can be mapped to three transmission units according to following program.

1. define h=R mod L.Formula (7)

2. define formula (8)

3. for k={0,1,2}

Figure 10 diagram the FLCS resource of corresponding the 2nd FLCS resource mapping scheme to the mapping of different initial FLCS tiles.Formula (7) cycles through the N of common segment _FLCSIndividual FLCS resource, and each FLCS resource mapped to corresponding initial FLCS tile, and from 0 beginning of FLCS tile and the FLCS tile 0 of after arriving FLCS tile L-1, reeling back.For a L FLCS resource, FLCS resource 0 to L-1 is mapped to initial FLCS tile 0 to L-1 respectively.For following L FLCS resource, FLCS resource L is mapped to initial FLCS tile 0 to L-1 respectively to 2L-1.Mapping is proceeded to be mapped to the initial FCLS tile of just fitting until all FLCS resources.Mapping among Figure 10 is symmetric, because L continuous FLCS resource is mapped to identical transmission unit in L the FLCS tile, and descends L FLCS resource to be mapped to another transmission unit in L the FLCS tile subsequently, or the like.

Figure 10 also shows the mapping of each FLCS resource of corresponding the 2nd FLCS resource mapping scheme to transmission unit.For each FLCS tile, formula (8) maps to the FLCS resource in the FLCS tile transmission unit 0, the 2nd FLCS resource is mapped to transmission unit 1, and the like.

It is h that each FLCS resource can be mapped to index ₀, h ₁And h ₂Three different FLCS tiles at the most in index be r ₀, r ₁And r ₂Three different transmission units, these index are to calculate suc as formula that kind shown in (9) and (10).h ₀Equal the initial FLCS tile index h that formula (7) is provided.h ₁And h ₂Corresponding to following two FLCS tiles, these two index can reel back 0 because of mod L operation after reaching L-1.r ₀Equal the transmission unit index r that formula (8) is provided.If L=2, then h ₂Can equal h, and if L=1, then h ₁And h ₂Can equal h.r ₁Equal r+M, and r ₂Equal r+2M.FLCS resource R is mapped to FLCS tile h ₀In transmission unit r ₀, FLCS tile h ₁In transmission unit r ₁, and FLCS tile h ₂In transmission unit r ₂

For the 2nd FLCS resource mapping scheme, transmission unit 0 to M-1 can be considered to belong to tile section 0, and transmission unit M can be considered to belong to tile section 1 to 2M-1, and transmission unit 2M can be considered to belong to tile section 3 to 3M-1.Each tile section can comprise M transmission unit.The 2nd FLCS resource mapping scheme can be similar to a FLCS resource mapping scheme, though three tile sections have different F _H ^k() and F _S ^k() mapping function.

System can only support a FLCS resource mapping scheme, only support the 2nd FLCS resource mapping scheme or this two kinds of mapping schemes.If support this two kinds of mapping schemes, then can selecting perhaps, the first or the 2nd FLCS resource mapping scheme uses.For example, can parameter UseDRCHForFLC be made as 0 to select a FLCS resource scheme or to be made as 1 to select the 2nd FLCS resource mapping scheme.

Below about common segment two kinds of FLCS resource mapping schemes have been described.The FLCS resource can otherwise map to the available transmission unit in L the FLCS tile of common segment based on other FLCS resource mapping schemes.

In a F-SCCH mapping scheme, P is divided into groups to mapping to the transmission unit in L the FLCS tile of common segment according to following program.

1. hop-ports counter i, block counter k, OFDM symbol counter j are initialized as 0.

2. initialization modulated symbol index p (n)=0, n=0 wherein, 1,2 ..., P-1.

3. if hop-ports counter i is the available hop-ports of F-SCCH, then

If the grouping that b. index is (a, 0) is to use QPSK to send, then define b=0

Otherwise, definition b=p (a) mod 2.Formula (12)

Be to use QPSK to send if c. divide into groups, then in k FLCS tile of common segment on i the hop-ports of j OFDM code element filling be that the index of the grouping of (a, 0) is the modulated symbol of p (a) from index.

If d. this grouping is to use 16-QAM to send; Then in k FLCS tile of common segment, filling from index on i the hop-ports of j OFDM code element is that (a, the index of grouping b) are the modulated symbol of

.

For a F-SCCH mapping scheme, program starts from OFDM code-element period 0, and traversal is through each all 16 hop-ports of L FLCS tile, and with a grouping to mapping to each transmission unit.The grouping that is mapped to the transmission unit among the hop-ports i of OFDM code-element period j among the FLCS tile k is to confirming according to formula (11).I increases progressively along with index, and it is right that formula (11) cycles through P grouping.

For each divides into groups to keep next code element that a counter p (a) and its indication will be sent in can be used for next right transmission unit of this grouping.Each right counter p (a) that divides into groups is initialized to 0.After this, when grouping was mapped to the available transmission unit and uses QPSK a, the code element p of grouping a (a) was mapped to this transmission unit and increments index p (a) subsequently.If use 16-QAM; Then alternately be mapped to and be used for the available transmission unit that it is right that this divides into groups from the code element of two groupings of grouping centering, for example, from (a that divides into groups; 0) code element is mapped to the available transmission unit that is used to divide into groups to a; Be mapped to next the available transmission unit that is used to divide into groups to a from the code element of divide into groups (a, 1) subsequently, or the like.

After traversal was through all the transmission unit/hop-ports in the OFDM code-element period, program pass was through all transmission units in next OFDM code-element period and repeat this mapping.Through all transmission units in all L the FLCS tiles of traversal common segment, each available transmission unit can and be used for F-SCCH by sign.

Figure 11 shows based on five groupings of the F-SCCH of F-SCCH mapping scheme example mappings to the transmission unit to common segment.Start from for simplicity, each divides into groups to a grouping that comprises that use QPSK sends.For each the FLCS tile in the common segment, being grouped among Figure 11 of each transmission unit of shining upon in the FLCS tile so far indicated.The transmission unit that is not useable for F-SCCH illustrates and is marked as " X " with gray shade.The transmission unit that can be used for F-SCCH by shadow-free illustrate, and come this transmission unit of mark with the index of the grouping that maps to each transmission unit.Start from for simplicity, Figure 11 supposes that only F-SCCH sends on common segment.If other control channels are sent out, the transmission unit that then is used for these other control channels is disabled and is marked as " X ".

From for simplicity, it is a grouping of 0 that Figure 11 only shows in this example in the middle of five groupings of sending on F-SCCH index.The code element of grouping 0 can be sent in each available transmission unit that grouping 0 is mapped to.Figure 11 shows some code elements of 0 mapping to 0 some the available transmission unit that are mapped to that divide into groups of dividing into groups.As described above, the code element of grouping 0 sequentially is mapped to and can be used for this transmission packets unit.Yet the mapping among Figure 11 looks like at random, because code element and FLCS tile be by numbering sequentially from top to bottom, and hop-ports is by numbering sequentially from top to bottom.The code element of each packets remaining can map to the available transmission unit in a similar manner.

Also can in K LAB section, send F-SCCH.In a kind of design, P grouping can in comprising each LAB section of 3 FLCS tiles, sending F-SCCH is right, and wherein P can exist with ... the number of available transmission unit of number and every LAB section of the right code element of per minute group.Index is 0 to PK-1 PK altogether and divides into groups to can in K LAB section, sending.Each divides into groups to comprising or under QPSK, sending and have an index (a; 0) two groupings of dividing into groups or under 16-QAM, sending and having index (a, 0) and (a, 1); Wherein a ∈ { 0; ..., PK-1} is the right index that divides into groups, and this right grouping 0 and 1 of dividing into groups (if being suitable for) of 0 and 1 sign.

2. initialization modulated symbol index p (n)=0, n=qP wherein ..., (q+1) P-1.

3. if hop-ports counter i is the available hop-ports of F-SCCH, then

A. define a=[(k+j+i) mod P]+qP.Formula (13)

If the grouping that b. index is (a, 0) is to use QPSK to send, then define b=0.

Otherwise, definition b=p (a) mod 2.Formula (14)

Be to use QPSK to send if c. divide into groups, then filling is that the index of the grouping of (a, 0) is the modulated symbol of p (a) from index on i the hop-ports of j OFDM code element in k the FLCS tile of LAB section q.

If d. this grouping is to use 16-QAM to send; Then in k the FLCS tile of LAB section q, filling from index on i the hop-ports of j OFDM code element is that (a, the index of grouping b) are the modulated symbol of .
