sBe the time slot index of a sub-frame, 0～25 representes 26 states respectively.But be not limited thereto kind of a sort method.
For example, { at this moment 00010001} always has 2 whens group/frequency position and is the measuring assembly of cooperating, and each group utilizes 5 bits to indicate respectively, needs the 2*5+8=18 bit altogether if the bitmap of 8 bits is designated as.1～4 is designated as any one position of four positions, and 5～10 is the combination of any two positions, four positions, and 11～14 is the combination of any three positions of four positions, and 15 is that four positions all comprise; 16～17 is that a position is selected in two positions, and 18 is that two positions all comprise, 19～22 is that (configuration 19～22 like table 4 bit 6 is respectively: (9,1) and (3 for the combination of one 4 port position and a 1or2 port position; 1), (9,1) and (0,1), (3,1) and (9; 1), (3,1) and (6,1)), 23～24 is that (configuration 23～24 like table 4 bit 4 is respectively: (11 for the combination of one 4 port position and two 1or2 port position; 1) and (5,1) and (2,1), (5,1) and (11; 1) and (8,1)), 25 is positions of 8 ports.
The cycle and the sub-frame offset of each channel state information reference signals in the cooperation measuring assembly can be distinguished separate configurations, and 2 groups need to dispose at least 2 cycles and sub-frame offset signaling in the measuring assembly of for example cooperating.
What the cycle of all each channel state information reference signals of sub-district and sub-frame offset can be unified in sub-district except that the service sub-district in the cooperation measuring assembly or the cooperation set is configured, and 2 groups only need configuration one-period and sub-frame offset signaling in the measuring assembly of for example cooperating.And this signaling configuration cycle that can utilize Serving cell zero energy or non-zero power configuration and sub-frame offset carry out the notice of recessiveness, do not need extra increase cycle and sub-frame offset signaling.
The above is merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to replacement and improvement etc., all should be included within protection scope of the present invention.
