One, auxiliary carriers carry PDSCH information or descending ACK/NACK information or descending CQI information
As shown in Fig. 3 a, it is the transmission direction schematic diagram of beared information on the main carrier of terminal scheduling and auxiliary carrier wave for base station, different by the transmission direction on the 4th subframe of every 5ms subframe of Fig. 3 a main carrier and auxiliary carrier wave, on main carrier, the transmission direction of beared information is up, and on auxiliary carrier wave, the transmission direction of beared information is descending, and terminal is not supported in the opposite communication of while travel direction on major-minor carrier wave.In the embodiment of the present invention, the transformat of beared information on the time-domain resource of auxiliary carrier wave and auxiliary carrier wave will be determined according to following steps in base station:
The time-domain resource that on subframe 4, main carrier carrying ascending control information (can be PUCCH or up CQI or uplink ACK/NACK etc.) takies is determined in step 3, base station;
During concrete enforcement, after determining the time-domain resource that main carrier takies, just can determine the running time-frequency resource position that main carrier takies, i.e. OFDM (OFDM, Orthogonal Frequency Division Multiplexing) character position; For example, as shown in Fig. 3 b, base station determines that main carrier takies the first two OFDM symbol of subframe 4 (OFDM symbol number 1-2);
The available time-domain resource of auxiliary carrier wave is determined in step 4, base station;
Concrete, because available frequency domain resource on auxiliary carrier wave is determined, therefore, after determining available time-domain resource, just can determine the OFDM character position that auxiliary carrier wave can be used, as shown in Fig. 3 b, base station determines that the available OFDM character position of auxiliary carrier wave comprises that rear 12 OFDM symbols can use (OFDM symbol number 3-14); For major-minor carrier wave, when its time-domain resource that takies not simultaneously, on the OFDM character position that each leisure takies, transmission information just can not disturb.
Concrete, determine the time-domain resource that Downlink Control Information takies available time-domain resource from auxiliary carrier wave, obtain the running time-frequency resource position (being specially the OFDM character position) that this Downlink Control Information takies; And the running time-frequency resource positional information that the scheduling PDCCH constantly before the moment indicates this Downlink Control Information to take in current scheduling; Perhaps, determine in current scheduling constantly, when the time-domain resource that on the time-domain resource that the PDCCH information of auxiliary carrier wave takies and main carrier, institute's beared information takies is not conflicted, the running time-frequency resource positional information that this Downlink Control Information of indication takies in current scheduling PDCCH constantly.
for example, if while carrying PDSCH information on auxiliary carrier wave, maximum schedulable sign resources is 3-14(OFDM symbol number 3-14) the OFDM symbol, and the OFDM positional information that takies of the descending PDSCH information of subframe 4 can be before this subframe the PDCCH information of descending sub frame in indicate, for example indicate the resource start position information of the descending PDSCH information of current subframe in the PDCCH information of the descending sub frame before this subframe, in addition, if the PDCCH position of the auxiliary carrier wave of this subframe (for example can be transmitted, in subframe 4 constantly, the OFDM character position that on the OFDM character position that PDCCH information on auxiliary carrier wave takies and main carrier, institute's beared information takies do not conflict (be in this example and do not take the 1-2OFDM symbol)), also can indicate in the PDCCH of this subframe, especially, can be with the OFDM character position when (being the time-domain resource that auxiliary carrier wave can be used) is divided into two discontinuous zones on time-domain if auxiliary carrier wave is determined in base station, can determine the OFDM character position that PDSCH information takies in the OFDM of arbitrary district inclusion character position, also can determine respectively the OFDM character position that PDSCH information takies in the OFDM of two district inclusions character position, if during the OFDM character position that in the OFDM character position that comprises in two zones respectively, definite PDSCH information takies, the OFDM character position that can indicate respectively PDSCH information to take in two zones of current subframe at the PDCCH of subframe before, for example, can indicate respectively the resource start position information of PDSCH information in two zones of current subframe at the PDCCH of subframe before, preferably, in order to save transfer resource, base station also can be in the PDCCH of subframe before indication PDSCH information in current scheduling unappropriated resource location information constantly.
If on auxiliary carrier wave when bearing downlink ACK/NACK or descending CQI information, descending ACK/NACK or descending CQI information will be limited on the 3-14OFDM symbol, correspondingly, the OFDM character position indication information that descending ACK/NACK or descending CQI information take can be carried in this subframe descending sub frame PDCCH information before and indicate, in addition,, if the PDCCH position of the auxiliary carrier wave of this subframe can be transmitted, also can indicate in the PDCCH of this subframe.Especially, can be with the OFDM character position when (being the time-domain resource that auxiliary carrier wave can be used) is divided into two discontinuous zones on time-domain if auxiliary carrier wave is determined in base station, can determine from arbitrary zone ACK/NACK information or CQI information, also can determine in two zones the OFDM character position that ACK/NACK information or CQI information take respectively.If while determining respectively OFDM character position that ACK/NACK information or CQI information takies in two zones, base station need to indicate respectively ACK/NACK information or CQI information to take in two zones in the PDCCH of subframe before OFDM character position information; Preferably, in order to save transfer resource, base station also can be in the PDCCH of subframe before indication ACK/NACK information or CQI information in the unappropriated OFDM character position of current subframe information.
