Step D30, NodeB, according to default timing relationship, send to UE by HS-DSCH transmission block by the HS-PDSCH channel on the carrier wave being scheduled;
Step D40, UE intercepts all HS-SCCH channels of distributing to UE in each subframe, according to the HS-DSCH control information of carrying on each the HS-SCCH channel listening to, receive and decoding HS-DSCH transmission block, according to decode results, generate ACK/NACK information, and according to the signal to noise ratio (Signal-Noise-Ratio of HS-PDSCH channel, hereinafter to be referred as: SNR) generate channel quality indication (Channel Quality Indicator, hereinafter to be referred as: CQI) information, and according to default timing relationship, ACK/NACK information and CQI information exchange are crossed on first carrier and sent to NodeB with the HS-SICH channel of HS-SCCH pairing,
After UE listens to HS-SCCH channel, according to the HS-DSCH control information of carrying on the HS-SCCH channel listening to, determine the HS-PDSCH channel of distributing to UE, and receive NodeB by the HS-DSCH transmission block of this HS-PDSCH channel transmission, according to the decoding parameter in HS-DSCH control information, HS-DSCH transmission block is carried out to decoding, and generate ACK/NACK information according to decode results.Concrete, when UE correct decoding HS-DSCH transmission block, generate ACK information; Otherwise, generate nack message.UE also will generate the CQI information of HS-PDSCH according to the SNR of HS-PDSCH.UE is by sending to NodeB with the HS-SICH channel of this HS-SCCH channel pairing by the ACK/NACK information of HS-DSCH transmission block and CQI information on first carrier.Here need explanation: HS-SCCH and HS-SICH by configuration.The every couple of HS-SCCH and HS-SICH comprise 1 HS-SCCH and 1 HS-SICH, are positioned on identical carrier wave.
Step D50, NodeB be according to default timing relationship, receives the HS-SICH channel on first carrier, extracts ACK/NACK information and CQI information, and by ACK/NACK information and CQI information reporting the scheduler to NodeB.
The multicarrier HSPA transmission method that the present embodiment provides, each carrier wave being scheduled by UE that each is scheduled carries out above-mentioned processing, can realize and in multi-carrier HSDPA, introduce MU MIMO technology, UE can obtain probability with the multiplexing same asset of other UE and equal that this UE obtains on each carrier wave and the probability sum of the multiplexing same asset of other UE on any one carrier wave, and UE can be significantly improved along with the increase of carrier number at descending peak rate and throughput.
