The CP length of all symbols is 16.67us.The uplink-downlink configuration supported is as shown in table 1:
Table 1
Wherein, to each subframe in a radio frames, " D " represents the subframe being exclusively used in downlink transfer, " U "
Representing the subframe being exclusively used in uplink, " S " represents special subframe, and it comprises descending pilot frequency time slot
(Downlink Pilot Time Slot is called for short DwPTS), (Guard Period is called for short at protection interval
And uplink pilot time slot (Uplink Pilot Time Slot, be called for short UpPTS) three parts GP).
In LTE system, in FDD system, owing to ascending-descending subframes is one to one, so working as PDSCH
(Physical Downlink Shared Channel, Physical Downlink Shared Channel) only comprises a transmission block
Time, UE to feed back ACK (determination)/NACK (negating) response message of 1 bit, work as PDSCH
When comprising two transmission blocks, UE to feed back the ACK/NACK response message of 2 bits, and UE uses
PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) format1a/1b
Send the ACK/NACK response message of 1/2 bit.In TDD system, due to ascending-descending subframes not
It is one to one, say, that the ACK/NACK response message that multiple descending sub frames are corresponding needs
Sending on the PUCCH channel of one sub-frame of uplink, the descending sub frame collection that wherein sub-frame of uplink is corresponding is charge-coupled
Become " bundling window ".The sending method of ACK/NACK response message has two kinds: Yi Zhongshi
Bundling (binding method), the core concept of the method be need this sub-frame of uplink feed back each
The ACK/NACK response message of the transmission block that individual descending sub frame is corresponding carries out logic and operation, if one
Individual descending sub frame has 2 transmission blocks, and UE to feed back the ACK/NACK response message of 2 bits, if
Each subframe only one of which transmission block, UE to feed back the ACK/NACK response message of 1 bit, UE
PUCCH format 1a/1b is used to send the ACK/NACK response message of this 1/2 bit；Another
Planting is multiplexing (PUCCH format1bwith channel selection, PUCCH format1b
Combined channel selects) method, the core concept of the method is to utilize different PUCCH channels and this letter
Modulation symbols different on road represents that the different of descending sub frame that needs feed back at this sub-frame of uplink feed back shapes
State, if there being multiple transmission block on descending sub frame, then is first fed back by multiple transmission blocks of descending sub frame
ACK/NACK carries out Channel assignment after carrying out logical AND (spatial bundling, spatial domain is bound) again,
UE uses format 1b with channel selection (selection of form 1b combined channel) to send
ACK/NACK response message.
Lte-a system is that lte-a system introduces carrier wave relative to LTE system the most significantly feature
Polymerization technique, namely carries out the bandwidth of LTE system being polymerized to obtain bigger bandwidth.Carry introducing
In the system of ripple polymerization, the carrier wave carrying out being polymerized is referred to as component carrier, and (Component Carrier is called for short
For CC), also referred to as one Serving cell (Serving Cell).It is also proposed that principal component carries
Ripple/community (Primary Component Carrier/Cell, referred to as PCC/PCell) and auxiliary component carrier
The concept of/community (Secondary Component Carrier/Cell, referred to as SCC/SCell).Entering
Go in the system of carrier aggregation, including at least a main Serving cell and auxiliary serving cell, the most main clothes
Business community is constantly in state of activation, and specifies that PUCCH only transmits on Pcell.
Under LTE-A carrier aggregation system, when HARQ (Hybrid Automatic Repeat Request,
Hybrid automatic repeat-request)-ACK response message when PUCCH sends, define two kinds of senders
Formula: use PUCCH format 1b combined channel to select (Format 1b with channel selection)
And PUCCH format 3 (PUCCH format 3).For configuring the UE of multiple Serving cells, as
If really UE at most can only support to be polymerized 2 Serving cells, described UE will use PUCCH format
The mode that 1b combined channel selects sends HARQ-ACK；If described UE can support more than 2
The polymerization of Serving cell, base station is to use PUCCH by further configuring described UE by high-level signaling
The mode that format 1b combined channel selects still uses PUCCH format 3 to send HARQ-ACK
Response message.In FDD system, PUCCH format3 uses the coding of single Reed-Muller (RM)
Mode, supports that the HARQ-ACK of most 10 bits sends, in TDD system, and PUCCH format3
Use the coded system of double RM, support that the HARQ-ACK of most 20 bits sends.TDD system
In it further provides for, when need send HARQ-ACK bit number more than 20 time, first will need send
HARQ-ACK re-uses PUCCH format3 and sends after carrying out space binding.
In prior art, PUCCH format3 supports that the HARQ-ACK of most 20 bits sends, and examines
Consider in later release, support that the carrier aggregation technology of at most 32 Serving cells causes needs to send
HARQ-ACK bit number exceeds well over 10/20 bit, thus PUCCH format3 cannot be used to send.
