In 2 symbol to time domains between the 3rd symbol reciprocal, then, the base station position of UERS resources in subframe determined by,
Reference signal is mapped in subframe and is sent to user equipment, so as to which UERS resources have moved to the centre position of each time slot,
Balanced distances of the UERS relative to other resources, can improve precision of channel estimation, and improve the demodulation performance on NCT.
On the basis of above-described embodiment, in FDD(Frequency Division Duplexing, hereinafter referred to as
FDD)In system, the 6th symbol and the 5th symbol progress PSS and SSS transmission in the time domain of subframe in the prior art can be avoided
When the generation that conflicts, or in time division duplex(Time Division Duplexing, hereinafter referred to as TDD)In system, subframe
The 5th symbol carries out the generation to conflict during SSS transmissions in time domain, further, because UERS resources are relative on prior art LCT
UERS resources time domain on translated, that is, moved to the centre position of each time slot, balanced UERS is relative to it
The distance of his resource, so as to improve precision of channel estimation.
Position of the UERS resources in subframe specifically can be set as follows:
If subframe is normal CP subframes, the position of UERS resources in the burst is the 2nd symbol in the time domain of subframe,
3rd symbol, the 9th symbol and the 10th symbol;
If subframe is extension CP subframes, the position of UERS resources in the burst is the 1st symbol in the time domain of subframe,
2nd symbol, the 7th symbol and the 8th symbol.
The present embodiment in FDD system, can be avoided in the prior art in subframe according to the setting of the position of UERS resources
The generation that middle progress PSS and SSS conflict when sending, or in a tdd system, the generation to conflict when carrying out SSS transmissions in subframe,
Further, because UERS resources are translated relative to the UERS resource locations on prior art LCT, that is, moved to every
The centre position of individual time slot, balanced distances of the UERS relative to other resources, so as to improve precision of channel estimation.

Include the first CSI-RS and/or the 2nd CSI-RS in instruction subframe.
Specifically, the first CSI-RS that can include in notice signaling for indicating subframe and/or the 2nd CSI-
RS resources, it can at least include 3 kinds of implementations, wherein,
First implementation, the first CSI-RS is only included in the notice signaling for indicating subframe, wherein, first
The resource index that CSI-RS includes is 0 to 19 CSI-RS, such as in the prior art CSI-s of the LCT in FDD system
RS resources.
Second implementation, the second CSI-RS is only included in the notice signaling for indicating subframe, wherein, including money
Original label is 20 to 31 CSI-RS, such as the CSI-RSs of LCT in a tdd system in the prior art.
3rd implementation, the notice signaling for indicating subframe include the first CSI-RS and provided with the 2nd CSI-RS
Source, specifically, in the prior art, LCT in order to avoid the position of the reference symbol of antenna port 5, is especially set in a tdd system
CSI-RS is put, both resource index was 20 to 31 CSI-RS.However, NCT no longer supports antenna port 5, therefore
NCT need not be in the CSI-RS that the resource index in prior art LCT TDD system is 20 to 31, simultaneously, it is contemplated that the
One CSI-RS may only use 20 resource index of the LCT in FDD system, therefore according to different editions in the prior art
Between CSI-RS overlap it is The more the better, can by the resource index of TDD system in LCT be 20 to 31 12 CSI-RS
Resource application in the present embodiment, i.e., sets the resource index of the second CSI-RS as 20 to 31 in the present embodiment.
