Description
Technical field
The present invention relates to field of communication technology more particularly to a kind of physical channel transmission method and equipment.
Background technique
Long term evolution (Long Term Evolution, LTE) frequency division duplex (Frequency Division Dual,
FDD frame structure Class1) is used in system, frame structure is as shown in Figure 1.In FDD system, uplink and downlink transmission uses different
Carrier frequency, but uplink and downlink transmission use identical frame structure.On each carrier, each 10 milliseconds of (ms) nothings
Line frame includes 10 1ms subframes, and each subframe is divided into two time slots, and each time slot is 0.5ms.What uplink and downlink data were sent
Transmission Time Interval (Transmission Time Interval, TTI) is 1ms.
Frame structure type 2 is used in LTE TDD system, frame structure is as shown in Figure 2.In a tdd system, uplink and downlink pass
Defeated different subframes or different time-gap using in identical frequency, each 10ms radio frames are made of two 5ms fields, each field
Subframe comprising 5 1ms length.Include three classes subframe in one radio frames, is respectively as follows: downlink subframe, sub-frame of uplink and special
Subframe, each special subframe are made of descender DwPTS, idle component GP and ascender UpPTS three parts, wherein
DwPTS can transmit descending pilot frequency, downlink service data and descending control signaling；GP does not transmit any signal；UpPTS is only transmitted
Accidental access signal and uplink pilot signal cannot transmit uplink business data or upstream control signaling.Each field includes extremely
A few downlink subframe and at least one sub-frame of uplink, and including most special subframes.
According to the definition of 3GPP TR36.912 Appendix B .2 chapters and sections, the user plane time delay (abbreviation U plane time delay) of LTE system
It is made of four base station (eNB) processing time, frame time alignment, TTI time and terminal device (UE) processing time parts,
In, frame time alignment, which refers to from business, reaches to business the waiting time that can be obtained between sub-frame transmission chance of eating dishes without rice or wine.
By taking LTE FDD downlink transfer as an example, since each subframe of FDD system has downlink transfer chance, when frame is aligned
Between average out to 0.5ms, base station handle the time in downlink be 1ms, in uplink be 1.5ms；Terminal device handles the time upper
It is 1ms when row, is 1.5ms in downlink.As shown in figure 3, in the case where not considering that HARQ is retransmitted, LTE FDD downlink U plane
Time delay=base station processing time 1ms+ frame time alignment 0.5ms+TTI time 1ms+ terminal device handles time 1.5ms, total 4ms.
Similarly, LTEFDD system does not consider hybrid automatic repeat-request (Hybrid Automatic Repeat Request, HARQ)
In the case where re-transmission, uplink U plane time delay is also 4ms.
The U plane time delay of LTE TDD system is equally handled by the base station time, frame time alignment, TTI time and terminal device
Handle four part of time composition, as shown in figure 4, wherein base station handle the time in downlink be 1ms, in uplink be 1.5ms；Eventually
The end equipment processing time is 1ms in uplink, is 1.5ms in downlink.The TTI time is all 1ms, frame time alignment with FDD phase
tFAUplink (Uplink, UL) used in the time reached with business and system-downlink (Downlink, DL) configuration is related.
For the UL-DL configuration #5 of the frame structure type 2 of TDD system as shown in Figure 5, if wherein base station is in subframe #1 completion transmitting terminal
Processing, could most send early in subframe #3, then the frame time alignment for being emitted to subframe of eating dishes without rice or wine is 1.5ms, the frame pair of remaining subframe
Neat time average out to 0.5ms, then the average value of the frame time alignment of downlink data is 0.6ms.Then UL-DL configures the downlink U of #5
Plane time delay is 4.1ms.
With the development of mobile communication business demand, future mobile communication system needs to define higher user face time delay
Energy.By being analyzed above it is found that shortening one of main method of user face delay performance is to reduce the length of TTI, such as by TTI
It shorten to 0.5ms.This just will appear the different terminal device of time delay length, be compatible with LTE Rel-8~Rel-13 terminal at the same time
In the system of equipment, when reverse link traffic channel corresponds to different length TTI, how uplink control channel is transmitted still without solution party
