Figure 13 a kind ofly is used to make the coding method 1300 of BS communicating control information to RS and UE according to what an exemplary embodiment illustrated.Referring to Figure 13, BS adds CRC parity check bit (1302) to DCI, and judges whether this DCI will be sent to RS (1304).If BS judges that RS is delivered in this not tendency to develop of DCI but UE (1304-"No") is delivered in tendency to develop, then BS uses the sign (for example RNTI of UE) of UE that the CRC parity check bit is carried out scrambling (1306), and also DCI is carried out chnnel coding to produce coded signal (1308).When UE received the DCI that has through the CRC of scrambling parity check bit, UE can carry out descrambling to the CRC parity check bit by the RNTI that uses himself and successfully receive DCI.
And if BS judges this DCI tendency to develop and deliver to RS (1304-"Yes") that then BS uses the sign (for example RNTI of RS) of RS that the CRC parity check bit is carried out scrambling (1310).BS judges also whether this DCI indicates the resource allocation (1312) that is used to relay the data to UE.If it is the resource allocation (1312-"Yes") that indication is used to relay the data to UE that BS judges DCI, then BS also uses the RNTI of UE that the CRC parity check bit is carried out scrambling (1314).(otherwise 1312-"No"), then BS carries out chnnel coding to DCI, to produce coded signal (1308).BS also can carry out rate-matched (1316) to these coded signals.When RS received the DCI that has through the CRC of scrambling parity check bit, RNTI that RS can be by using himself and/or the RNTI of UE carried out descrambling to the CRC parity check bit and successfully receive DCI.
Figure 14 is used to make the process 1400 of BS communicating control information to RS and UE according to what an exemplary embodiment illustrated.For example, BS can have the DCI 1402 of CRC parity check bit to transmit as additional the control information that is used for UE, and the control information that will be used for RS has the DCI 1404 of CRC parity check bit to transmit as additional.
Referring to Figure 14, BS is encoding among some CCE 1406 (for example 4 CCE) DCI 1402 for being sent to UE, and DCI 1404 is encoding among the CCE 1408 (i.e. 4 CCE) of similar number for being sent to RS.BS also transmits CCE 1406 and CCE 1408 in the different frequency resource.On the UE end, UE can use blind interpretation method 200 (Fig. 2) to decipher CCE 1406, and on the RS end, RS also can use blind interpretation method 200 (Fig. 2) to decipher CCE 1408.Thus, UE and RS just can decode respectively CCE 1406 and CCE 1408, and after CRC, receive DCI 1402 and DCI1404.
In an exemplary embodiment, BS transmits CCE 1406 and CCE 1408 in same subframe N.Explain as Figure 13, because BS can use UE and RS RNTI separately that the CRC parity check bit of UE and RS is carried out scrambling, so UE and RS can distinguish correctly decode CCE 1406 and CCE 1408.
