Embodiment
The present invention is specially adapted to have the LTE (3GPP long evolving system) of RS and IMT-Advanced (super 3G system).
After introducing RS, between BS and the RS and the transmission means between RS and the UT need rethink, mainly be demand, for example for the demand of reliability or whether need to consider power saving etc. according to receiving terminal.(as shown in Figure 1, 2) can obtain frequency diversity gain if down control channel adopts the FDM mode, promptly can be assigned to control information on the different subcarrier of distinct symbols, thereby can improve the reliability of control channel; If adopt TDM mode (as shown in Figure 3) then can help micro sleep pattern, promptly receiving terminal can obtain power saving effect preferably.In addition, the present invention has also utilized a kind of new transmission means HDM (HybridDivision Multiplex on the basis of existing TDM and FDM mode, it is multiplexing to mix branch) mode (shown in Fig. 4,5), be the mode that TDM and FDM combine, the HDM mode also can obtain better frequency diversity gain than the TDM mode.Among Fig. 1 to Fig. 5,

Expression control information (control), represents data service (data).
After introducing RS, according to the type difference of RS, consider the characteristic of frame structure and the different RS of RS, the multiplex mode of control channel also is different, mainly is to decide according to the demand of receiving terminal, specifies as follows:
When nontransparent RS, Downlink Control Information and data service all must be transferred to UT by RS.Nontransparent RS generally can not enter micro sleep pattern, and RS is receiving control information and business datum constantly.In order better to adjust the covering power and the frequency diversity gain of control information, at descending RS time slot, BS is handed down to control information employing FDM or the TDM+FDM form of RS, BS utilizes descending RS time slot to be issued to RS, RS carries out decoding processing after receiving complete time slot, afterwards control information is issued to UT again according to the mode of TDM.And the UT that can cover for BS directly is issued to UT to control information according to the mode of TDM.Particularly: the transmission of control information can be adopted following scheme:
● FDM or TDM+FDM are preferably adopted in the transmission of BS--＞RS down control channel, also TDM;
Owing to need not to consider the power saving problem of RS, preferably adopt FDM or TDM+FDM to transmit.Subcarrier mapping mode as shown in Figure 1 can be adopted when adopting the FDM mode, subcarrier mapping mode as shown in Figure 4 can be adopted when adopting the TDM+FDM mode, among the figure
Figure A20081008275100061
Expression pilot tone (Pilot),
Figure A20081008275100062
Expression control information (control), represents data service (data).
● TDM is preferably adopted in the transmission of RS--＞UT down control channel, also FDM or TDM+FDM;
Consider the power saving problem of UT, so the down control channel of RS and UT preferably adopts the TDM mode.
● TDM is preferably adopted in the transmission of BS--＞UT Downlink Control Information, also FDM or TDM+FDM;
Equally, consider the power saving problem of recipient UT, BS and UT down control channel preferably adopt the mode of TDM.
As seen, as UT during, all preferably adopt the TDM mode with the control channel of UT direct communication as receiving terminal.
When transparent RS, have only data service to be transferred to UT by RS.So transparent RS need take into full account micro sleep pattern, especially mobile RS battery is limited in one's ability.The micro sleep pattern that is to say RS only is used for transparent RS, and BS can activate RS and enter micro sleep, and RSmicro sleep pattern is identical with UT.It is identical to the mode that transparent RS and UT adopt that BS issues control information, and promptly BS directly is issued to RS and UT to control information according to the mode of TDM.The transmission of Downlink Control Information can be adopted following scheme:
● TDM is preferably adopted in the transmission of BS--＞RS down control channel, also FDM or
TDM+FDM；
Enter into micro sleep pattern for the ease of RS, so the down control channel of BS and RS preferably adopts the TDM mode.
● TDM is preferably adopted in the transmission of BS--＞UT Downlink Control Information, also FDM or TDM+FDM;
Equally, consider the power saving problem of UT, the down control channel of BS and UT preferably adopts the TDM mode.
Subcarrier mapping for FDM or TDM+FDM mode can be fixed, also can be that frequency hopping produces the subcarrier mapping ruler, for example Fig. 2 and Fig. 5 are through FDM mode and TDM+FDM mode after the frequency hopping, for fixed frequency, antijamming capability is stronger after the frequency hopping, and frequency hopping can adopt any in the existing frequency hopping.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
