Description
Technical field
The present invention relates to the technology of uplink transmission block setting and transmission block emission in advanced Long Term Evolution (LTE-Advanced) GSM, what relate in particular to Physical Downlink Control Channel (PDCCH) format 4 in a kind of LTE-Advanced physical layer forbids transmission block method for transmitting, system, base station and subscriber equipment.

Here it is to be noted: need to support that the situation of single transport piece emission specifically comprises following content:
One: data re-transmission.Concrete, if in two transmission blocks that when new data sends, sent, one of them occurs and send mistake and need to retransmit, and the another one transmission block is correct and when having no new data to transmit, judging needs to support the single transport piece to launch.
Two: order descends.Concrete, because the order of channel matrix descends when causing being not suitable for high-order mimo, judging needs to support the emission of single transport piece.
Below in conjunction with accompanying drawing the enforcement of technical scheme is done further to describe in detail.
A kind of transmission block method for transmitting of forbidding, this method comprises: when base station side is encoded, the combined information of Modulation and Coding Scheme (MCS) and new data indication (NDI) is set, indicates and forbid the transmission block launched, UE is dispatched; When the UE side is decoded, parse the combined information of Modulation and Coding Scheme and new data indication, forbid launching the indicated transmission block of this combined information.
Further, the combined information of Modulation and Coding Scheme and new data indication specifically comprises: the value that Modulation and Coding Scheme is got is 29,30 or 31, and the value of the value of new data indication during with last the transmission is different.Here, because the value of new data indication can be 0 or 1, therefore, the value of the value of new data indication during with last transmission is different, is meant that upset has taken place the value that new data is indicated, and comprises that value becomes 1 from 0, and perhaps value becomes 0 from 1.
Further; The combined information of Modulation and Coding Scheme and new data indication is set; Indicate before the transmission block of forbidding launching, this method also comprises: the base station is configured to the radio resource control layer of UE can support a kind of emission mode of the multiplexing emission of upstream space through radio resource control layer.This moment, UE can launch two transmission blocks in a Transmission Time Interval.
