It is assumed that UE1 version is R11.When network side needs to send downlink data to UE1, network side is believed by physical layer
The different mapping resource locations for receiving subframe business datum of order notice receiving side, network side can contemplate addition 2,3 or 4 bits
Into downstream grants information with CRS that need to be silent to UE notices resource location.
As shown in figure 3, if silent CRS resource location is needed using 4 bit notifications, then can apply all
12 kinds of states in 16 kinds of states:00,01,11,21,31,41,51,02,12,22,04,14,24, included in every kind of state
Two digital first digits to need the biasing of the CRS of silence frequency domain position in resource block, second digit is
Antenna port number.Because the frequency offset of a CRS port can be 0 to 5, therefore the state of 1 CRS port is:01,
11,21,31,41,51;Because the frequency offset of two-port can be 0 to 2, then the state of 2 ports is:02,21,22;Due to four
The frequency offset of port can be 0 to 2, then the state of 4 ports is:01,14,24.Described 00 represents not needing silence.
If it is considered that saving control signaling, silent CRS resource-niche can be needed only according to 2 ports and 4 ports notice
Put, at this moment need to introduce 3 bits, 7 kinds of states in all 8 kinds of states can be applied:00,02,12,22,04,14,24.
If notify to need silent CRS resource location, it is necessary to introduce 2 bits only according to 2 ports, including 4 kinds of states:
00,02,12,22.
Notify to need during silent CRS resource location according to 0 to 1 port, it is necessary to take the 0th in each subframe, 4,
7th, 11 OFDM symbols;, it is necessary to take in each subframe when notifying to need silent CRS resource location according to 2 to 3 ports
1st, 8 OFDM symbol.
UE can detect the silent CRS information bits in descending control signaling, to obtain the demapping resource of business datum
Position.

It is assumed that UE1 version is R11, when network side needs to send downlink data to UE1, network side is believed by physical layer
The different mapping resource locations for receiving subframe business datum of order notice receiving side, network side can contemplate addition 3,6 or 9 bits
Into downstream grants information, to notify to need the CRS of silence resource location corresponding to UE.
As shown in Figure 3, it may be considered that 6 CRS positions and the 2nd, 8 OFDM symbol in the 0th, 4,7,11 OFDM symbol
On 3 CRS positions, 9 positions altogether, it is therefore desirable to using the bitmap sequences of 9 bits.
If it is considered that always notify to need silent CRS resource location according to 2 ports, then it is contemplated that the 0th, 4,7,
3 CRS positions being respectively present on 3 CRS positions being respectively present in 11 OFDM symbols, and the 1st, 8 OFDM, altogether
6 positions, it is therefore desirable to using the bitmap sequences of 6 bits.
If it is considered that always notify to need silent CRS resource location according to 4 ports, then it is contemplated that the 0th, 1,4,
7th, 3 CRS positions in 8,11 OFDM symbols, it is therefore desirable to using the bitmap sequences of 3 bits.
If only consider to notify to need silent CRS resource location according to 2 ports, then it is contemplated that the 0th, 4,7,11
3 CRS positions in individual OFDM symbol, it is therefore desirable to using the bitmap sequences of 3 bits.
UE with the bitmap sequences in blind check downstream grants signaling, can need silent CRS resource location with acquisition, from
And obtain the demapping resource location of business datum.

Network side needs to know the CRS configuring conditions for the node that UE is detected during down-going synchronous, then according to same
The CRS time-frequency locations and port number of the node of step are come the mapping that is transmitted.UE is according to detecting during down-going synchronous
The CRS configuring conditions of node carry out the demapping of data.

Network side needs to know the CRS configuring conditions for the node that UE is detected during down-going synchronous, then according to same
The CRS time-frequency locations and port number of the node of step are come the mapping that is transmitted.UE is according to detecting during down-going synchronous
The CRS configuring conditions of node carry out the demapping of data.Network side also needs to add 1 bit in downstream grants signaling to notify
Whether UE present sub-frames are MBSFN sub-frame, if present sub-frame is MBSFN sub-frame, network side need not when mapping data
Consider CRS configuring condition, i.e., network side is when mapping data, it is not necessary to considers CRS position;UE is in demapping data
Without the concern for CRS configuring condition.
It should be noted that heretofore described CRS port informations and being related to the CRS information of silence, refer to data not
The time-frequency resource elements that can be mapped.In addition, the resource location of the CRS that need to be silent can be time-frequency location etc..
Visible in summary, either method is still reflected positioned at network side, the device of receiving side, data resource of the invention
Position treatment technology is penetrated, ensures that UE can correctly judge data resource mapping position under different scenes and CoMP transmission pattern,
So as to be properly received and detect required data, data resource can be saved as far as possible with for transmission services data.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the scope of the present invention.
