Description

A kind of method for transmitting signals and device

Technical field

The present invention relates to wireless communication technology field, particularly relate to a kind of method for transmitting signals and device.

Background technology

In order to realize the reliability of end-to-end transmission, existing method specifically includes that

Method 1, autonomous retransmission (Automatic Repeat reQuest, ARQ) and mixed automatic retransfer (Hybrid Automatic Repeat reQuest, HARQ):

ARQ is by adding check bit in transmitting data information bit, and receiving terminal can accurately judge number According to whether being properly received and feed back to transmitting terminal.If it occur that erroneous transmissions, transmitting terminal retransmits data, directly To being properly received or time-out.What HARQ transmitted the most every time is different redundancy versions, and this can bring Coding merges gain, can improve the correct probability of transmission further.

Method 1 ensure that the accuracy of data reaches predetermined requirement, but confirmation repeatedly and retransmit meeting Bring the delay of transmission, be suitable for the business less sensitive to time delay.

Method 2, time diversity are transmitted:

There is fading effect in the channel of mobile radio system, different time signals declines the most in time Subtract difference, if signal transmits during deep fade, then easily cause mistake.Can be by by signals disperse Transmit in different timeslices, thus overcome the impact deeply declined, improve the reliability of transmission.In order to ensure The effect of time diversity, needs the time interval of necessity, when being correlated with preferably over channel between being transmitted several times Between, thus too increase the time delay of transmitting.

Method 3, space diversity transmission:

Spatial decomposition transmission then utilizes the irrelevance of the sending and receiving end channel of diverse location, by signal respectively many Individual receipts or send out on antenna respectively or combine transmission, thus improve the correctness of packet transmission.Common Space diversity such as Rake receiver (a kind of can separate multipath signal and effectively merge multipath signal energy Final receiver), multiple-input and multiple-output (Multiple-Input Multiple-Output, MIMO) etc..

Method 4, channel redundancy encode:

Channel redundancy encodes the redundancy encoding by signal produces unnecessary original signal according to certain rule, Then receiving terminal is decoded according to the rule of equity, so when there is a small amount of bit information error of transmission, Receiving terminal can be correct correct transmission mistake.

In following 5G business, reliability that some business needs are high and extremely low time delay.Said method 1 Require time for transmission is repeated several times with method 2, it is impossible to meet delay requirement.As a example by LTE system, it is The subframe lengths of system is 1ms, and the round trip transmission delay being sent to receive is usually more than 3ms, in order to ensure Correct confirmation, then retransmit the time about 4ms needing to wait 1 time, in order to reach the Block Error Rate of necessity, and 3 Secondary re-transmission then needs to wait more than 12ms, is far longer than the requirement for time delay of the 5G business.

Said method 3 requires that channel is the most uncorrelated in space, needs between multiple transmission or reception antenna Keeping bigger distance, to the miniaturization of mobile communication system equipment, the project installation of base station etc. brings tired Difficulty, so system antenna number is generally not capable of designing too much incoherent antenna, said method 3 is the most uncomfortable For following 5G business.

Certain error correcting capability is there is in said method 4 to the opposing mistake brought of channel fading, but on the one hand Redundancy can be caused too high, and system transfers efficiency is low, on the other hand the limited error recovery capability of chnnel coding, It is difficult to ensure that the Block Error Rate of below 10-6 magnitude in fading channel, particularly it is constantly in deeply when subscriber channel It is difficult to during the decline phase correct mistake, it is impossible to meet the requirement for reliability of the 5G business.

Detailed description of the invention

Along with the development of mobile communication, system bandwidth is more and more wider, and such as 4G LTE just have employed basic band The system design of wide 20MHz.Signal is during radio transmission, and its decline is except being presented as time domain and sky Between decline outside, can also be embodied as frequency domain decline.The frequency domain of signal becomes with the delay spread of wireless channel fading period Inverse ratio.Such as, in the channel circumstance of urban district, the root mean square value of its delay spread is 2 (us), then corresponding The coherence bandwidth of the wireless channel being sent to reception is 500 (KHz).It is to say, signal is at frequency F1 With when transmitting on frequency F1+500KHz, channel fading characteristic is correlated with hardly.So, for improving the time The reliability of upper single transmission, the scheme that the embodiment of the present invention proposes, signal is incoherent in multiple frequencies Transmit on Resource Unit.

Below in conjunction with accompanying drawing, the technical scheme providing the embodiment of the present invention is described in detail.

The flow chart of the method for transmitting signals that Fig. 1 provides for the embodiment of the present invention, specifically includes and operates as follows:

Step 100, transmitting terminal obtain and carry out at least two Resource Unit that signal transmission is used, Qi Zhongren Anticipate and there is frequency interval between two Resource Units.

Step 110, transmitting terminal send the signal after coding on above-mentioned at least two Resource Unit.

The technical scheme that the embodiment of the present invention provides, uses frequency diversity transmission, is sent to exceeding by signal Transmit in multiple frequency resources of the coherence bandwidth of the wireless channel received, on the basis not increasing propagation delay time On, improve transmission reliability.It is spatially uncorrelated, therefore, it is possible to be applied to further, since need not meet Compact apparatus.

Wherein, it is preferred that the frequency interval between any two Resource Unit is not less than the nothing being sent to reception The coherence bandwidth of line channel.

Wherein, in step 110, both can be by the signals disperse after coding at above-mentioned at least two Resource Unit Upper transmission；The signal after sending coding can also be repeated on above-mentioned at least two Resource Unit.

Wherein, the implementation of above-mentioned steps 100 may is that

1 transmission error probability requirement that transmitting terminal transmits according to signal, determines that carrying out signal transmission is used Number of resource units so that carry out the error of transmission first of signal transmission according to the number of resource units determined Probability summation is less than 1 transmission error probability requirement, and number of resource units is the integer not less than 2；

Transmitting terminal is according to overall system bandwidth, the coherence bandwidth of the wireless channel being sent to reception and above-mentioned resource list Unit's quantity, obtains and carries out the Resource Unit that signal transmission is used.

Wherein, the delay spread that transmitting terminal transmits according to signal, determine the phase of the wireless channel being sent to reception Dry bandwidth, its specific implementation has multiple.Such as, the historical information that transmitting terminal utilizes signal to transmit determines Delay spread, determines the coherence bandwidth of the wireless channel being sent to reception according to this delay spread；Or, send out The pilot signal that sending end utilizes receiving terminal to send determines delay spread, determines according to this delay spread and is sent to connect The coherence bandwidth of the wireless channel received；Or, transmitting terminal is to receiving terminal pilot signal transmitted, and receives this and connect The coherence bandwidth of the wireless channel being sent to receive of receiving end feedback, wherein, is sent to the wireless channel received Coherence bandwidth be that receiving terminal determines according to pilot signal and feeds back.

The inverse of maximum multipath time delay it is approximately equal to owing to being sent to the coherence bandwidth of the wireless channel of reception.Cause This, it is possible to use the delay spread of signal transmission estimates the coherence bandwidth of the wireless channel being sent to reception. Such as, the value of the root-mean-square (RMS) of the delay spread of signal transmission is 2 (us), then, corresponding sends out The coherence bandwidth of the wireless channel delivering to reception is approximately 500 (KHz).

Wherein, 1 transmission error probability requires to determine according to actual application scenarios.Transmit according to signal 1 transmission error probability requirement, determine and carry out the number of resource units that signal transmission is used, its realize Mode has multiple.Such as: the error probability of estimation single single carrier transmission；According to 1 transmission error probability Require and the error probability of single single carrier transmission, determine and carry out the Resource Unit number that signal transmission is used Amount.This implementation is particularly suited for the data after encoding and repeats the field of transmission on multiple Resource Units Scape.Accordingly, above-mentioned number of resource units is iterative transfer times.Assume the mistake of single single carrier transmission Probability is P by mistake, and in n incoherent frequency, the cumulative error probability of transmission is at least Pⁿ, 1 transmission Error probability requires as P '.It is possible to by PⁿClosest to but the value of n less than P ' as above-mentioned Number of resource units.

Particularly, on multiple Resource Units, transmission is repeated if used, then:

1 error probability requires to be p1, and single single carrier transmission error probability is p2, (1 > p2 > p1), then Iterative transfer times n reaching 1 error probability requirement is:

The most such as, according to 1 transmission error probability requirement of signal transmission, and single Resource Unit transmission quantity Limit, determine and carry out the number of resource units that signal transmission is used.Concrete so that the resource list determined Unit's quantity had both met erroneous transmissions probability demand first, and on each Resource Unit, the semaphore of transmission does not surpasses Cross single Resource Unit transmission quantity to limit.

Such as, a width of N of overall system, the coherence bandwidth of the wireless channel being sent to reception is W, and signal passes Defeated used number of resource units is n, and the frequency interval between adjacent two Resource Units is D, it is desirable to D >=W.In order to ensure that irrelevance is more preferable, signal is dispersed in as far as possible in whole system bandwidth, it may be assumed that as Really W >=N/n, D=W；If W is < N/n, D=N/n.

Corresponding transport stream signal journey can be as shown in Figure 2.Wherein, original information block is carried out redundancy encoding After obtain redundant coded information block, Redundant coded data block is split into n Resource Block and is dispersed in n resource Send on unit.

Based on above-mentioned any means embodiment, before step 110, it is also possible to signal transmission will be carried out and made At least two Resource Unit and the coded system of signal notify to receiving terminal.

If it should be pointed out that, not by carry out at least two Resource Unit that signal transmission used notify to Receiving terminal, then, transmitting terminal and receiving terminal determine Resource Unit in the same fashion.If not by signal Coded system notify to receiving terminal, then, transmitting terminal is compiled according to the coded system arranged with receiving terminal Code.
