Wherein, specific resources refers to the resource of the ad-hoc location in 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) comprise 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 as 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.

As 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 is the specific resources different from the position of the shared specific resources of a PCFICH on the 1st the OFDM symbol at busy channel B place also.

As 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 common subframe and the special subframe of other various structures certainly only for illustrating, and lift no longer in detail herein.

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

For instance, the base station can be with the frequency domain width configuration of channel A (M=1,2,3 ...), be 0,1,2,3 with the time domain width configuration of CoMP user's dedicated channel ... individual OFDM symbol, wherein Expression Resource Block number of subcarriers.Especially, there is no a CoMP user access if the residential quarter 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 time domain width of channel A can be arranged in advance with terminal in the base station, and this moment, the base station can generate the configuration indication information of the frequency domain width that is used to indicate channel A; Perhaps the frequency domain width of channel A can be arranged in advance with terminal in the base station, and this moment, the base station can generate the configuration indication information of the time domain width that is used to indicate channel A.

For instance, the corresponding relation of the channel A time-frequency configuration that the configuration indication information of the channel A that the base station generates is indicated with it 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 respectively four kinds of different time-frequency configurations of channel A.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 generating content in the present embodiment is that 00 configuration indication information is to indicate current subframe as common subframe.

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

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

Under a kind of application scenarios, the base station can configure 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, as shown in Fig. 5-a or Fig. 5-b in the special subframe of structure, take a PCFICH and the 2nd PCFICH respectively 4 fixing REG of the 1st the OFDM symbol at busy channel B place as example, use

The resource original position that represents the REG that a PCFICH takies,

The resource original position that represents 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:

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, as 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, as 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 the specific position 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, CoMP subscriber equipment and non-CoMP subscriber equipment can adopt respectively different processing modes to process the special subframe that the base station sends.

For instance, if CoMP UE is receiving equipment, CoMP UE can receive special subframe, the 2nd PCFICH channel of detection and demodulation special subframe, the configuration indication information of the channel A of acquisition the 2nd PCFICH channel bearing; Then can according to the configuration indication information of the channel A that obtains, determine the time-frequency configuration of channel A; 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 the resource scheduling information that can further carry according to channel A etc., the business datum of reception and demodulation PDSCH carrying etc.

If LTE-A Non-CoMP UE is 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, LTE-A Non-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 configures 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.
