Principal element, but exactly limited frequency spectrum resource excites the appearance of new technology.Capacity and covering in a wireless communication system be
Two important performance indicators.
In existing long term evolution (Long Term Evolution, referred to as LTE) system, in order to enhance upper line number
It is believed that road covering performance, a variety of advanced technologies have been used, including：(1) interference coordination (Inter-Cell of minizone
Interference Coordination, referred to as ICIC), such as high interference instruction (High Interference
Indication, HII) and overload instruction (Overload Indication, referred to as OI) method；(2) multiple-input and multiple-output
(Multiple Input Multiple Output, referred to as MIMO), for example, space diversity (Space Diversity, referred to as
For SD) and beam forming (Beamforming, referred to as BF) method；(3) cooperative multi-point (Coordinated Multiple
Point, referred to as CoMP), it is the technology to be grown up based on MIMO, such as cooperative scheduling/cooperative beam molding
(Coordinated Scheduling/Coordinated Beamforming, referred to as CS/CB) with combine receive (Joint
Receiver, referred to as JR) method.Due in current network and following a period of time, user equipment (User Equipment,
Referred to as UE) it is single antenna, MIMO and CoMP technologies are limited for the improvement of uplink.
In existing LTE system, although being used for multiple technologies to improve the transmission performance of uplink, especially on
Row covering performance, but found by current network test and emulation, the Physical Uplink Shared Channel (Physical of moderate rate
Uplink Shared Channel, referred to as PUSCH) it is still the channel that covering performance is limited in each channel, reason is
The transmission power of UE is limited.This proposes new demand to uplink moderate rate covering performance.
In order to further promote the covering of uplink moderate rate, transmission time interval (tti) bundle (Transmission Time
Internal Bundling, referred to as TTI Bundling) scheme has been proposed.TTI Bundling schemes refer to scheduling
Device is the radio resource that UE is allocated more than 1 TTI.The basic thought of the program is that UE is allowed to be continuously transmitted on continuous T TI together
One transmission block (Transmission Block, referred to as TB) redundancy versions (Redundancy Version, referred to as RV).Tool
Body, Fig. 1 is the uplink schematic diagram using TTI Bundling schemes according to the relevant technologies, as shown in Figure 1, by filling out
Add cyclic redundancy check (Cyclic Redundancy Check, referred to as CRC) bit, channel coding (Channel
Coding, referred to as CC) and rate-matched (Rate Matching, referred to as RM) process, 4 RV (RV0 related with certain TB
To RV3) it is generated；Then, above-mentioned 4 RV (RV0 to RV3) are sent out on continuous 4 TTI (TTI n to TTI n+3) respectively
It send.Wherein, compared with traditional scheme, TTI Bundling schemes, which are supported to send, has bigger transport block size
The transmission block of (Transmission Block Size, referred to as TBS) saves control and opens to obtain encoding and decoding gain
Pin finally realizes the raising of uplink covering.
It, must be accurate between eNB and UE to ensure that enhancing node B (evolved NodeB, referred to as eNB) is correctly decoded TB
It really realizes the synchronization of corresponding TBS, but how to be carried out when being carried out data transmission using TTI Bundling in the related technology
