Mode one, implicit expression advice method.

If index information is a cell number; Sub-district determination module 210 is after the cell number of receiving from network side; Receive the order of cell IDs according to receiver module 200, confirm the cell number corresponding district sign received, and definite cell ID corresponding district sub-district that is CoMP participating.

Wherein, cell number is that network side is confirmed according to the order of sending cell ID.

Comprise 3 sub-districts in the measurement cell basic set of receiving such as receiver module 200, i.e. A sub-district, B sub-district and C sub-district, sub-district determination module 210 confirms that the bit number that each cell number takies is ceil (log2 (3))=2bit.

Suppose that the order that receiver module 200 receives cell ID is the cell ID that receives the A sub-district earlier; Receive the cell ID of B sub-district again; Receive the cell ID of C sub-district at last, so sub-district determination module 210 can be confirmed the cell number of 3 sub-districts: (promptly 10) numbered and be 3 to A sub-district corresponding district numbering is 1 (promptly 00), B sub-district corresponding district numbering are 2 (promptly 01) and C sub-district corresponding district.

Suppose that the cell number that sub-district determination module 210 is received is 00 and 01, then sub-district determination module 210 confirms that A sub-district and B sub-district are the sub-districts of CoMP participating.

If index information is a bit; Sub-district determination module 210 is behind the bitmap that receives from network side; Receive the order of cell ID according to receiver module 200; Each bit corresponding district sign among the bitmap that confirms to receive is according to the value of bit and the sub-district of the definite CoMP participating of bit corresponding district sign.

Wherein, whether the sub-district in the measurement cell basic set of this bit correspondence of the value representation of bit belongs to the CoMP participating set of cells, and the order of each bit is that network side is confirmed according to the order of sending cell ID among the bitmap.

Such as: comprise 3 sub-districts in the measurement cell basic set that receiver module 200 is received, i.e. A sub-district, B sub-district and C sub-district, sub-district determination module 210 confirms that the bit number that bitmap take is 3bit.

The bitmap from network side that sub-district determination module 210 is received is 110.

Suppose that the order that receiver module 200 receives cell ID is the cell ID that receives the A sub-district earlier; Receive the cell ID of B sub-district again; Receive the cell ID of C sub-district at last; So sub-district determination module 210 just can confirm among the bitmap, the cell ID of corresponding the 1st reception of the 1st number (promptly 1), i.e. A sub-district; Corresponding the 2nd cell ID that receives of the 2nd number (promptly 1), i.e. B sub-district, the 3rd number (promptly 0) correspondence the 3rd cell ID that receives, i.e. C sub-district.

If index information is a bit; Sub-district determination module 210 is at the bitmap that receives from network side, and receiver module 200 is when receiving with cell ID that cell number is bound, according to the size of the cell number of receiving; Cell ID to receiving sorts; And according to the cell ID after the ordering, each bit corresponding district sign among the bitmap that confirms to receive is according to the value of bit and the sub-district of the definite CoMP participating of bit corresponding district sign.

Wherein, whether the sub-district in the measurement cell basic set of this bit correspondence of the value representation of bit belongs to the CoMP participating set of cells, and the order of each bit is that network side is confirmed according to the size of cell number among the bitmap.

Sub-district determination module 210 sorts to the cell ID of receiving according to the size (such as order from small to large) of the cell number of receiving, i.e. order after the cell ID ordering is the cell ID of A sub-district, the cell ID of C sub-district, the cell ID of B sub-district.

The bitmap from network side that sub-district determination module 210 is received is 101.

Because the order after the cell ID ordering is the cell ID of A sub-district, the cell ID of C sub-district, the cell ID of B sub-district is so sub-district determination module 210 just can be confirmed among the bitmap cell ID of the 1st number (promptly 1) corresponding A sub-district; The cell ID of the 2nd number (promptly 0) corresponding C sub-district; The cell ID of the 3rd number (promptly 1) corresponding B sub-district.
