Description
Technical field
The present invention relates to the upstream data in wireless communication field, more particularly to a kind of tdd systems sends and receives
Method and apparatus.
Background technology
In Long Term Evolution（Long Term Evolution, LTE）In system, terminal is limited to（User Equipment,
UE）Maximum transmission power, each packet is in a Transmission Time Interval（Transmission Time Interval,
TTI）Interior utilizable power is very limited, therefore, under severe channel conditions, uplink does not reach performance requirement.In order to
Up covering is improved, LTE system adopts TTI binding（bundling）Technology, expects at least up to high speed uplink packet access
（High Speed Uplink Packet Access, HSUPA）Performance.So-called TTI bundling technologies, are UE bases
In a scheduling instruction of base station, same data transmission block is sent in multiple subframes（Transport Block, TB）In channel
Multiple redundancy versions after coding（Redundancy Version, RV）, as such, it is possible to the transmission gain of upstream data is improved,
So as to strengthen the coverage effect of upward signal.The plurality of sub-frame of uplink is referred to as a binding subframe beam（bundle）.
In time division duplex（Time division duplex, TDD）In-LTE system, introduce for three kinds of uplink-downlink configurations
TTI bundling technologies, and employ unified binding size（bundling size）, i.e., include in one bundle
Sub-frame of uplink number.Other uplink-downlink configurations do not support TTI bundling technologies.
For TDD-LTE system, continuous sub-frame of uplink number is less than bundle sizes, therefore multiple redundancies of packet
Version（RV）Send in discrete sub-frame of uplink.The TDD uplink-downlink configurations 0,1 and 6 of configuration TTI bundling operations
Uplink hybrid automatic repeat request（Hybrid Automatic Repeat reQuest, HARQ）Process is respectively such as Fig. 1-Fig. 3 institutes
Show.
For TDD uplink-downlink configurations 0, in non-bundling, ascending HARQ course number is 7；Configuration TTI
During bundling, ascending HARQ course number is 3.
For TDD uplink-downlink configurations 1, in non-bundling, ascending HARQ course number is 4；Configuration TTI
During bundling, ascending HARQ course number is 2.
For TDD uplink-downlink configurations 6, in non-bundling, ascending HARQ course number is 6；Configuration TTI
During bundling, ascending HARQ course number is 3.
In existing TDD-LTE system, there is following four：
First, only three kinds uplink-downlink configurations（That is uplink-downlink configuration 0,1,6）Support TTI bundling, other up-downgoings
Configuration cannot support TTI bundling, cause up covering to be limited；
Second, support that three kinds of uplink-downlink configurations of TTI bundling adopt unified bundling size, not pin
The sub-frame of uplink number of every kind of uplink-downlink configuration is optimized so that sub-frame of uplink utilization rate does not reach 100%, causes up covering
Lid is impaired；As shown in figure 1, in uplink-downlink configuration 0, though configuration it is maximum enter number of passes（3）, still have two sub-frame of uplink skies
It is not busy, it is impossible to transmit for TTI bundling.
3rd, due to HARQ sequential relationships complexity, it is impossible to support semi-continuous scheduling（SPS）；Semi-continuous scheduling is by high level
The periodic scheduling of triggering, it is possible to reduce the expense of uplink scheduling signaling, is particularly well-suited to the scene of small data packets（Such as VoIP industry
Business）.Dispatching cycle is by a series of values { sf10, sf20, sf32, sf40, sf64, sf80, sf128, sf160, sf320, sf640 }
Composition, unit is subframe（sf）.It is actual to be configured by high-level signaling using which value.But which value no matter selected with current TDD systems
The TTI bundling of system cannot be used in combination.By taking VoIP typical case's applications as an example, dispatching cycle is 20ms, and using upper and lower
Row configuration 1.If adopting SPS, when first VoIP bag is in the 3rd subframe of radio frames N（Subframe 2）Upper scheduled transmission, then
Three subframe of two VoIP bags in subframe N+2（Subframe 2）Upper scheduled transmission.But according to HARQ sequential relationships, subframe N+2
The 3rd subframe（Subframe 2）For the re-transmission of first VoIP bag.When retransmission takes place, first VoIP bag of re-transmission and
Two VoIP bags can be clashed.Therefore, in order to avoid conflict, current TDD system TTI bundling does not support SPS.Up and down
Go to match somebody with somebody to set to 0 same problem is there is also with 6.
4th, Bundling subframe is continuous sub-frame of uplink, and time diversity gain is limited.
