Suppose that the numbering of 9 subbands is respectively [Subband 0, Subband 1 ..., Subband 8], the numbering (a kind of representation of position) of corresponding continuous print logical resource unit is respectively [SLRU ₀, SLRU ₁, SLRU ₂..., SLRU ₃₄, SLRU ₃₅], comprise 4 continuous print logical resource unit in each subband.

Alternatively, 1 bit in resource allocation information unit outside above-mentioned 11 bits can be used to indicate the resource index mode of current employing.Such as, in this example, have employed 1 bit before the bit that resource indication information takies, when described 1 bit is " 1 ", represents and adopt following resource index mode, otherwise, adopt other indexed mode.

Preferably, above-mentioned 11 bits are made to be used to indicate resource index based on 2 subbands (that is, specifying number is 2, at this for 2, but is not limited thereto).

Continuous print 7 the MSB bits be positioned at above are used to indicate index value corresponding to above-mentioned 2 subbands, index value production process following (also can adopt other index value production method, as long as ensure the combination one_to_one corresponding of index value and indicated subband numbering):

From 9 subband, select 2 subbands arbitrarily, and encoded by the numbering of following formula to these 2 subbands, wherein,

Index u and v represents that, by the numbering of two subbands selected, RIF represents the index value corresponding to above-mentioned two subbands.Such as, be numbered 2 and 4, i.e. u=2, v=4 in this example by the subband selected, then the index value of its correspondence is:

$\mathrm{RIF}=\left(\begin{array}{c}2\\ 1\end{array}\right)+\left(\begin{array}{c}4\\ 2\end{array}\right)=C_2^1+C_4^2=8$

Finally, one can be produced and there is C ₉ ²the indexed table of=36 list items, each list item describes the numbering of two subbands in 9 subbands and the corresponding relation of its index value; Base station or terminal can by tabling look-up, or perform the corresponding encryption algorithm of above-mentioned encryption algorithm or decoding algorithm to obtain two subbands numberings corresponding to this index value.

Alternatively optional execution mode, directly can construct an indexed table, and this form at least exists a list item, the generation of this list item is not based on said process; Now, base station or terminal can only obtain two subbands numberings corresponding to the index value of two subbands by the mode of tabling look-up.

Wherein, specify that a subband in two subbands is fully assigned, another subband is partly distributed, 1 bit be positioned at after 7 MSB bits is used partly to be distributed to indicate which subband, such as, in this example, this bit is set to " 1 ", represents that Subband 4 is partly distributed.

3 last bits are used to indicate the continuous print logical resource unit be assigned with in the subband that above-mentioned quilt partly distributes, be Subband 4 in this example, as illustrated in fig. 15b, wherein, " X " represents the logical resource unit be assigned with selected to logical resource unit indicating means.Namely in this example, the final logical resource element number distributed is [SLRU ₈, SLRU ₉, SLRU ₁₀, SLRU ₁₁, SLRU ₁₆, SLRU ₁₇].

It should be noted that, above-described embodiment is not limited to certain specific system bandwidth, but the number of the subband indicated as required or logical resource unit, combinationally use the various methods in above-described embodiment, such as, 16 continuous print logical resource unit, namely 4 subbands, can corresponding 5M, the standard bandwidth of 10M or 20M or equivalent bandwidth (such as, using ToneDropping technology), or the irregular bandwidth of 8.75M, but the indicating means of its Resources allocation is consistent under various bandwidth.Further, method described above and embodiment by formula of equal value or form or pictorial representation, as long as the effect of the indicated logical resource unit reached or resource allocation unit is identical, all can be considered as equivalent method, repeats no more.

Because resource in IEEE 802.16m system comprises subband and continuous print logical resource unit, institute is very applicable to this system in this way.For other communication system, also there is Practical significance.

In sum, it is lower that the method that above-described embodiment provides has complexity, realizes simple, and the advantage that resource indicating range is wider.

Obviously, those skilled in the art should be understood that, above-mentioned of the present invention each module or each step can realize with general calculation element, they can concentrate on single calculation element, or be distributed on network that multiple calculation element forms, alternatively, they can realize with the executable program code of calculation element, thus, they can be stored and be performed by calculation element in the storage device, and in some cases, step shown or described by can performing with the order be different from herein, or they are made into each integrated circuit modules respectively, or the multiple module in them or step are made into single integrated circuit module to realize.Like this, the present invention is not restricted to any specific hardware and software combination.

The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
