Wherein, specific resources is meant the resource of the ad-hoc location in the subframe that receiving equipment can be clear and definite.

Generally speaking, the minimum particle size of resource mapping is referred to as resource units (RE, Resource Element), 1 resource group (REG, Resource Element Group) comprises 4 RE that can be used to bear control information in, 1 control channel unit (CCE, Control Channel Element) generally includes 9 REG.

For instance, the structure of the special subframe of base station configuration can be shown in Fig. 5-a, Fig. 5-b, Fig. 5-c, Fig. 5-d, Fig. 5-e or Fig. 5-f, but is not limited to this.

Shown in Fig. 5-a, the base station can be whole frequency ranges of special subframe with the frequency domain width configuration of channel A, and the time domain width configuration is one or more OFDM symbols.Specific resources on the 1st the OFDM symbol at the one PCFICH busy channel B place, the 2nd PCFICH also on the 1st the OFDM symbol at busy channel B place with the different specific resources in position of the shared specific resources of a PCFICH.

Shown in Fig. 5-e and Fig. 5-f, specific resources on the 1st the OFDM symbol at the one PCFICH busy channel B place, specific resources on a plurality of OFDM symbols at the 2nd PCFICH busy channel B place, for example base station and UE can be respectively ad-hoc location by the resource on a plurality of OFDM symbols at clear and definite the 2nd PCFICH busy channel B place of interweave algorithm and deinterleaving algorithm.

Be understandable that the common subframe of said structure and special subframe can also have the common subframe and the special subframe of other multiple structure certainly only for illustrating, no longer detailed the act herein.

Under a kind of application scenarios, consider that constantly the CoMP user in the sub-district and non-CoMP user's ratio may dynamic change in difference, for guaranteeing that channel resource makes full use of, the base station can be according to the current distribution proportion of above-mentioned all kinds user in the sub-district, frequency domain width and/or the time domain width of the channel A of real-time and dynamic adjustment configuration special subframe.

For instance, the base station can be with the frequency domain width configuration of channel A

(M=1,2,3 ...), be 0,1,2 with the time domain width configuration of CoMP user's dedicated channel, 3... OFDM symbol, wherein

Expression Resource Block number of subcarriers.Especially, do not have CoMP user to insert if the sub-district is current, the base station also can be directly is zero with frequency domain width and/or the time domain width configuration of channel A.

Under a kind of application scenarios, the base station can be according to the time-frequency configuring condition of channel A, generates the configuration indication information of channel A, and the configuration indication information of the channel A that the base station generates is mainly used in the time domain width of indicating channel A and/or frequency domain width etc.

Under another kind of application scenarios, the base station can be arranged the time domain width of channel A in advance with terminal, and this moment, the base station can generate the configuration indication information of the frequency domain width that is used for indicating channel A; Perhaps the base station can be arranged the frequency domain width of channel A in advance with terminal, and this moment, the base station can generate the configuration indication information of the time domain width that is used for indicating channel A.

Present embodiment generates simultaneously with the base station, and the configuration indication information of the time-frequency width of indicating channel A is that example is specifically described.Be understandable that the content and the form of the configuration indication information of the channel A that the base station generates can be content arbitrarily and the forms that subscriber equipment can be discerned.

Certainly, the base station can also be according to the time-frequency configuring condition of channel B, generates the configuration indication information of channel B, and the channel B configuration indication information that the base station generates is mainly used in the time domain width of indicating channel B and/or frequency domain width etc.

For instance, the configuration indication information channel A time-frequency configured corresponding relation indicated with it of the channel A that the base station generates can be as shown in table 1, but be not limited to this:

Table 1

As shown in table 1, the base station can utilize the configuration indication information of two bits to indicate four kinds of different time-frequency configurations of channel A respectively.For example, when the configuration indication information was 01, the frequency domain width of indicating channel A configuration was the frequency range of subframe 1/3, and the time domain width of configuration is 2 OFDM symbols of subframe.

Be understandable that because receiving equipment can clear and definite current subframe be common subframe or special subframe in advance, therefore, not needing to generate content in the present embodiment and be 00 configuration indication information is common subframe to indicate current subframe.

302, the base station is dispatched to the configuration indication information of second channel in the special subframe.

Under a kind of application scenarios, for further improving transmission reliability, the base station can be earlier carried out chnnel coding with the configuration indication information of the channel A that generates and is handled, and the configuration indication information that will carry out the channel A after the chnnel coding is dispatched among the 2nd PCFICH of special subframe.

For instance, the base station can become the configuration indication information chnnel coding of 2 bits the data of 32 bits, with the data dispatch of 32 bits in the channel of special subframe.

The base station also can be carried out chnnel coding with the configuration indication information of the channel B that generates and handled, and the configuration indication information that will carry out the channel B after the chnnel coding is dispatched among the PCFICH of special subframe.

Under a kind of application scenarios, the base station can dispose the shared specific resources of the 2nd PCFICH and be evenly distributed in one or more OFDM symbols as far as possible, so that receiving equipment obtains the time of the 2nd PCFICH institute beared information and/or the diversity reception gain of frequency.

For instance, shown in Fig. 5-a or Fig. 5-b in the special subframe of structure, with a PCFICH and the 2nd PCFICH respectively 4 fixing REG of the 1st the OFDM symbol at busy channel B place be example, use

The resource original position of representing the REG that a PCFICH takies,

The resource original position of representing the REG that the 2nd PCFICH takies.

The resource original position of the REG of the 1st the OFDM symbol at the one PCFICH busy channel B place can be as follows, but be not limited to this:

The resource original position of the 1st REG: $K_1^1=\stackrel{\‾}{k}=(N_{\mathrm{sc}}^{\mathrm{RB}}/2)\·\left(N_{\mathrm{ID}}^{\mathrm{cell}}\mathrm{mod}2N_{\mathrm{RB}}^{\mathrm{DL}}\right)$

The resource original position of the 2nd REG: $K_1^2=\stackrel{\‾}{k}+(N_{\mathrm{RB}}^{\mathrm{DL}}/2)\·N_{\mathrm{sc}}^{\mathrm{RB}}/2$

The resource original position of the 3rd REG: $K_1^3=\stackrel{\‾}{k}+(2N_{\mathrm{RB}}^{\mathrm{DL}}/2)\·N_{\mathrm{sc}}^{\mathrm{RB}}/2$

The resource original position of the 4th REG: $K_1^4=\stackrel{\‾}{k}+(3N_{\mathrm{RB}}^{\mathrm{DL}}/2)\·N_{\mathrm{sc}}^{\mathrm{RB}}/2$

The resource original position of the REG of the 1st the OFDM symbol at the 2nd PCFICH busy channel B place can be as follows, but be not limited to this:

The resource original position of the 1st REG: $K_2^1=\stackrel{\‾}{k}+N_{\mathrm{sc}}^{\mathrm{RB}}/2$

The resource original position of the 2nd REG: $K_2^2=\stackrel{\‾}{k}+[(N_{\mathrm{RB}}^{\mathrm{DL}}/2)+1]\·N_{\mathrm{sc}}^{\mathrm{RB}}/2$

The resource original position of the 3rd REG: $K_2^3=\stackrel{\‾}{k}+[(2N_{\mathrm{RB}}^{\mathrm{DL}}/2)+1]\·N_{\mathrm{sc}}^{\mathrm{RB}}/2$

The resource original position of the 4th REG: $K_2^4=\stackrel{\‾}{k}+[(3N_{\mathrm{RB}}^{\mathrm{DL}}/2)+1]\·N_{\mathrm{sc}}^{\mathrm{RB}}/2$

Again for instance, shown in Fig. 5-c or Fig. 5-d in the special subframe of structure, with a PCFICH 4 REG of the 1st the OFDM symbol at busy channel B place still, 4 REG of the 1st the OFDM symbol at the 2nd PCFICH busy channel A place are example.

The resource original position of the REG of the 1st the OFDM symbol at the 2nd PCFICH busy channel A place can be as follows, but be not limited to this:

The resource original position of the 1st REG: $K_1^1=\stackrel{\‾}{k}=(N_{\mathrm{sc}}^{\mathrm{RB}}/2)\·\left(N_{\mathrm{ID}}^{\mathrm{cell}}\mathrm{mod}{2N}_{\mathrm{RB}}^{\mathrm{DL}}\right)$

The resource original position of the 2nd REG: $K_1^2=\stackrel{\‾}{k}+(N_{\mathrm{RB}}^{\mathrm{DL}}/2)\·N_{\mathrm{sc}}^{\mathrm{RB}}/2$

The resource original position of the 3rd REG: $K_1^3=\stackrel{\‾}{k}+({2N}_{\mathrm{RB}}^{\mathrm{DL}}/2)\·N_{\mathrm{sc}}^{\mathrm{RB}}/2$

The resource original position of the 4th REG: $K_1^4=\stackrel{\‾}{k}+({3N}_{\mathrm{RB}}^{\mathrm{DL}}/2)\·N_{\mathrm{sc}}^{\mathrm{RB}}/2$

Wherein, above-mentioned

The expression physical-layer cell identifier,

Expression Resource Block number of subcarriers,

Expression downlink bandwidth Resource Block quantity.

Again for instance, shown in Fig. 5-e or Fig. 5-f in the special subframe of structure, the one PCFICH is 4 fixing REG of the 1st the OFDM symbol at busy channel B place still, and the resource that the 2nd PCFICH takies can be dispersed in the ad-hoc location on a plurality of OFDM symbols at channel B place relatively, so that receiving equipment obtains the time of the 2nd PCFICH institute beared information and the diversity reception gain of frequency.

In actual applications, the base station can be by the ad-hoc location of the resource on a plurality of OFDM symbols at clear and definite the 2nd PCFICH busy channel B place of the algorithm that interweaves, accordingly, UE can be by the ad-hoc location of the resource on a plurality of OFDM symbols at clear and definite the 2nd PCFICH busy channel B place of deinterleaving algorithm.

Be understandable that, only for illustrating, the shared specific resources of a PCFICH and the 2nd PCFICH also can be distributed in other certain location on one or more OFDM symbols in the position of the specific resources that the one PCFICH of foregoing description and the 2nd PCFICH are shared.

The base station can also be dispatched to control information to be sent or out of Memory the channel A of special subframe, with business datum to be sent or other data dispatch PDSCH to special subframe.

303, the base station sends special subframe.

Under a kind of application scenarios, the CoMP subscriber equipment can adopt different processing modes to handle the special subframe that the base station sends respectively with non-CoMP subscriber equipment.

For instance, if CoMP UE is receiving equipment, then CoMP UE can receive special subframe, detects and the 2nd PCFICH channel of demodulation special subframe, obtains the configuration indication information of the channel A of the 2nd PCFICH channel bearing; Can determine the time-frequency configuration of channel A according to the configuration indication information of the channel A that obtains then; And further according to the time-frequency configuration of channel A, receive and the control information of demodulated channel A carrying and the time domain starting point of definite PDSCH, the control information of channel A carrying can comprise the resource scheduling information of user service data; Then can be further according to the resource scheduling information of channel A carrying etc., receive and demodulation PDSCH loaded service data etc.

If LTE-A Non-CoMP UE is a receiving equipment, for LTE-A Non-CoMP UE, may carry its control information by channel B, also may carry its control information by channel A.

If carry its control information by channel B, then LTE-ANon-CoMP UE can receive special subframe, and at first detect and demodulation the one PCFICH channel, according to the configuration indication information of the channel B of a PCFICH channel bearing, receive and control information that demodulated channel B carries; And then detection and demodulation the 2nd PCFICH channel, the time-frequency that obtains channel A disposes and determines the time domain starting point of PDSCH; And according to the control information reception of channel B carrying and the user service data of demodulation PDSCH carrying etc.
