This.Except satisfaction or more than 3GPP TR 25.913：“Requirements for Evolved UTRA(E-UTRA)and
Outside all related needs of Evolved UTRAN (E-UTRAN) ", the IMT-Advanced of ITU-R propositions is also met or exceeded
Demand.Wherein, refer to the demand of LTERelease-8 backward compatibility：The terminal of LTERelease-8 can be in LTE-
Work in the network of Advanced；The terminal of LTE-Advanced can work in the network of LTE Release-8.
In addition, LTE-Advanced should be able to be in different size of spectrum disposition, including frequency more broader than LTE Release-8
Spectrum configuration (such as the continuous frequency spectrum resource of 100MHz) under work, to reach higher performance and Target peak rate.Due to
LTE-Advanced networks are required to access LTE user, so its operational frequency bands needs to cover current LTE frequency bands, at this
There is no the spectral bandwidth of assignable continuous 100MHz in frequency range.So LTE-Advanced needs one of solution directly
Connection technology is that the continuous component carrier frequency (frequency spectrum) (Component carrier) by several distributions on different frequency bands is aggregating
Form the 100MHz bandwidth that LTE-Advanced can be used.I.e. for the frequency spectrum after aggregation, n component carrier frequency is divided into
(frequency spectrum) (Component carrier), the frequency spectrum in each component carrier frequency (frequency spectrum) is continuous.

Window is the corresponding all descending sub frames of sub-frame of uplink (it should be noted that " correspondence " herein refers to that these descending sub frames exist
The sub-frame of uplink feedback acknowledgment information).
For TDD dual-modes, due to there may be configuration of the descending sub frame more than sub-frame of uplink in a radio frame
Scene, it is possible that the feedback information that there are multiple descending sub frames sends in same sub-frame of uplink.It is such a up
The corresponding multiple descending sub frames of subframe are referred to as feedback window.
Under to TDD ACK/NACK bindings or multiplexer mode, when feedback window is only 1,Determination method be：
For PDSCH transmission is indicated by PDCCH, or the transmission of the descending SPS releases of PDCCH instructions,Using
Piecemeal interweaves with mapping and obtains.For PDSCH transmission is indicated by PDCCH, thenDetermined by high-rise configuration and table 1, table one
