In LTE TDD systems, because ascending-descending subframes are not one-to-one, that is to say, that multiple descending sub frames
HARQ-ACK response messages need to send on the PUCCH channels of a sub-frame of uplink, descending son wherein corresponding to sub-frame of uplink
Frame set constitutes feedback window.The sending method of HARQ-ACK response messages has two kinds:One kind is to bind (bundling), the party
The core concept of method is the HARQ-ACK responses transmission block corresponding to each descending sub frame for needing to feed back in the sub-frame of uplink
Message carries out logic and operation, if a descending sub frame has 2 transmission blocks, UE will feed back the HARQ-ACK responses letter of 2 bits
Breath, if each subframe only has a transmission block, UE will feed back the HARQ-ACK response messages of 1 bit;Another kind is multiplexing
(multiplexing), this method refers mainly to PUCCH format 1b combined channels selection (PUCCH format 1b in LTE
With channel selection) method, the core concept of this method is to utilize on different PUCCH channels and the channel not
With modulation symbol come represent need the sub-frame of uplink feedback descending sub frame different feedback states, if on descending sub frame
There are multiple transmission blocks, then the HARQ-ACK for first feeding back multiple streams of code words of descending sub frame carries out spatial logic with (being also referred to as
Spatial domain bind) after carry out Channel assignment again, then using PUCCH format 1b send.Wherein, bind in window (on namely
Row subframe needs the descending sub frame set fed back) HARQ-ACK (i) response messages and the PUCCH channels of selection of each descending sub frame
