Description
Technical field
The present invention relates to the transmission plan in wireless communication system, more particularly to based on Long Term Evolution (LTE-Long
Term Evolution) low latency transmission method and apparatus.
Background technology
In 3GPP (3rd Generation Partner Project, third generation cooperative partner program) RAN (Radio
Access Network, wireless access network) determine in #63 plenary session to study reducing the delay of LTE network this problem.
The delay of LTE network includes eating dishes without rice or wine to postpone, signal transacting delay, transmission delay between node etc..With wireless access network and
The upgrading of core net, transmission delay are can be effectively reduced.With the application for the new semiconductor for possessing higher height reason speed, signal
Processing delay is significantly reduced.In RAN#72 plenary session, the achievement in research based on early stage, 3GPP is determined to shortening TTI
The delay of (Transmission Time Interval, Transmission Time Interval) and signal transacting is standardized.
In existing LTE system, either subframe or PRB (Physical Resource Block) are right by a TTI
(Pair) 1ms (mill i-second, millisecond) is corresponded in time.In order to reduce network delay, 3GPP determines that standardization is shorter
TTI, row such as LTE FDD (Frequency Division Duplexing, FDD) system introducing 2 OFDM
(Orthogonal Frequency Division Multiplexing, OFDM) symbol or 1 time slot it is descending
TTI length, the up TTI length of 2 OFDM symbols, 4 OFDM symbols or 1 time slot.In LTE TDD (Time Division
Duplexing, time division duplex) system up-downgoing introduce 1 time slot TTI length.
LTE is an interference-limited wireless communication system, in order to by interference randomization so as to improve transmission performance,
Most of physical channel in LTE has all carried out Scrambling Operation before modulation.Used scrambler for 31 ranks Gold sequence simultaneously
And the maker of the scrambler can reinitialize in each subframe, i.e., initial scrambler sequence is and the son in a radio frames
Frame number linear correlation.
The content of the invention
After short TTI is introduced, for example, the short TTI of 2 OFDM symbol length, existing scrambler initial method, i.e., per frame
Reinitialize, can not be randomized interference between short TTI, so as to cause downstream transmission in multiple short TTI
It is continually subjected to compared with strong jamming.
Eat dishes without rice or wine to be delayed to reduce, one intuitively method be the brand-new TTI less than 1ms of design included in existing
In LTE subframes, thus make that multiple TTI less than 1ms can be included in an existing LTE subframe.If continue to use existing LTE
In scrambling code sequence generation method the channel transmitted in less than 1ms TTI is scrambled, will result in a subframe
Multiple TTI less than 1ms transmission all scrambler sequence is initialized using subframe numbers of the subframe in radio frames, from
And interference randomization can not be carried out between the TTI less than 1ms, may cause downstream transmission it is multiple less than 1ms TTI in connect
It is continuous to introduce or decline transmission performance by compared with strong jamming.Therefore the invention discloses it is a kind of can be in the TTI less than 1ms
Transmission provide interference randomization scheme.
For LTE after short TTI is introduced existing interference randomization problem, the invention provides solution.Need
