In order to be described further to above-mentioned wireless communications method shown in FIG. 1, Fig. 2 is referred to, it illustrates the present invention The method flow diagram for the wireless communications method that another embodiment provides.The present embodiment is mainly applied to the wireless communications method Come in user equipment in M2M system for example, the wireless communications method may include:

Step 201, user equipment obtain the frequency domain spread spectrum factor, symbol level spreading factor and Transmission Time Interval grade spread spectrum because Son；

At least one in the frequency domain spread spectrum factor, symbol level spreading factor and Transmission Time Interval grade spreading factor be The spreading factor that base station is sent.Spreading factor is the integer more than or equal to 1.

User equipment can receive the frequency domain spread spectrum factor, symbol level spreading factor and the Transmission Time Interval of base station transmission Grade spreading factor；

Alternatively, user equipment also can receive the frequency domain spread spectrum factor, symbol level spreading factor and the transmission of base station transmission Part spreading factor in time interval grade spreading factor, and obtain the pre-stored frequency domain spread spectrum factor, symbol level spread spectrum Rest part spreading factor in the factor and Transmission Time Interval grade spreading factor.

Wherein, can be divided into can for the frequency domain spread spectrum factor, symbol level spreading factor and Transmission Time Interval grade spreading factor Become spreading factor and fixed spreading factor, wherein variable bandspread factor is that base station is determined according to predetermined spreading factor selection strategy Part spreading factor, fixed spreading factor is that system presets and is stored in the expansion of the rest part in user equipment and base station The frequency factor.

Specifically, when the frequency domain spread spectrum factor, symbol level spreading factor and Transmission Time Interval grade spreading factor be all can Become spreading factor when, user equipment receive base station sent with signaling method the frequency domain spread spectrum factor, symbol level spreading factor and Transmission Time Interval grade spreading factor；When the frequency domain spread spectrum factor, symbol level spreading factor and Transmission Time Interval grade spread spectrum because When part spreading factor in son is variable bandspread factor, user equipment receives the frequency domain spread spectrum that base station is sent with signaling method Part spreading factor in the factor, symbol level spreading factor and Transmission Time Interval grade spreading factor, and obtain pre-stored Rest part spreading factor in the frequency domain spread spectrum factor, symbol level spreading factor and Transmission Time Interval grade spreading factor.

Different spreading factors can be sent by base station with different types of signaling.For example, symbol level spreading factor It can be sent in a manner of physical layer signaling by base station, Transmission Time Interval grade spreading factor can be by base station in a manner of high-level signaling It sends；Alternatively, symbol level spreading factor can be by high-level signaling mode, Transmission Time Interval grade spreading factor can be by physical layer Signaling method is sent.

Step 202, user equipment is according between the frequency domain spread spectrum factor, symbol level spreading factor and the transmission time got Frequency domain spread spectrum, symbol level spread spectrum and Transmission Time Interval grade is carried out respectively to the first information to be sent every grade spreading factor to spread, Information after obtaining the first spread spectrum；

User equipment can generate the frequency expansion sequence of frequency domain spread spectrum according to the frequency domain spread spectrum factor got；According to generation The frequency expansion sequence of frequency domain spread spectrum carries out frequency domain spread spectrum to the first information to be sent.

Specifically, user equipment generates frequency domain according to the frequency domain spread spectrum factor got and expands by taking existing LTE system as an example The frequency expansion sequence of frequency, it is assumed that the frequency domain spread spectrum factor is N₁, then the frequency domain spread spectrum sequence generated is c₁=(c₁[0], c₁[1] ..., c₁[N-1]).User equipment can carry out frequency domain spread spectrum to the first information to be sent according to following formula:

Wherein, s₁It (t) is the information of first information to be sent after frequency domain spread spectrum, N₁For the frequency domain spread spectrum factor, a₁ [k] is k-th of data of first information to be sent, c₁[n] is n-th element in the frequency domain spread spectrum sequence, T_sFor input Data symbol duration,For subcarrier spacing, f₀For the carrier frequency of the 0th subcarrier,

The meaning of above-mentioned formula 1 is that the data of the first information to be sent repeat N on frequency domain₁Expand after secondary multiplied by corresponding Then frequency sequence is added, to obtain the effect of frequency domain spread spectrum.

It should be noted that above-mentioned frequency domain spread spectrum sequence can be ZC (Zadoff-Chu) sequence or Gray code.

User equipment can generate the frequency expansion sequence of symbol level spread spectrum according to the symbol level spreading factor got；According to life At the frequency expansion sequence of symbol level spread spectrum symbol level spread spectrum is carried out to the first information to be sent.

Specifically, user equipment generates the frequency expansion sequence that symbol level is spread according to the symbol level spreading factor got, it is false If symbol level spreading factor is N₂, then the symbol level frequency expansion sequence generated is c₂=(c₂[0], c₂[1] ..., c₂[N-1]).With Family equipment can carry out Transmission Time Interval grade spread spectrum to the first information to be sent according to following formula:

Wherein, s₂It (t) is signal of first information to be sent after symbol level is spread, N₂For symbol level spreading factor, s′₂It (t) is the signal of the first information to be sent, c₂[n] is the nth elements in symbol level frequency expansion sequence, T_sTo input number According to symbol period,

Above-mentioned 2 meaning of formula is that symbol period remains unchanged, multiplied by the code of a symbol level frequency expansion sequence on each symbol Piece is intuitively seen, is equivalent to and N is repeated in a symbol of information to be sent in the time domain₂Multiplied by corresponding symbol level after secondary Frequency expansion sequence achievees the effect that symbol level is spread.

User equipment can generate Transmission Time Interval grade spread spectrum according to the Transmission Time Interval grade spreading factor got Frequency expansion sequence；Transmission time is carried out to the first information to be sent according to the frequency expansion sequence of the Transmission Time Interval grade of generation spread spectrum Bay level spread spectrum.

Expand specifically, user equipment generates Transmission Time Interval grade according to the Transmission Time Interval grade spreading factor got The frequency expansion sequence of frequency, it is assumed that Transmission Time Interval grade spreading factor is N₃, then the Transmission Time Interval grade frequency expansion sequence generated is c₃ =(c₃[0], c₃[1] ..., c₃[N-1]).When user equipment can transmit the first information to be sent according to following formula Between bay level spread:

Wherein, s₃(t) signal for the first information to be sent after Transmission Time Interval grade spread spectrum, N₃For transmission time Bay level spreading factor, s '₃It (t) is the signal of the first information to be sent, c₃[n] is in Transmission Time Interval grade frequency expansion sequence Nth elements, T_TTiFor the Transmission Time Interval of the first information to be sent,

The meaning of above-mentioned formula 3 is similar with formula 2, and only Transmission Time Interval is constant, transmits in each Transmission Time Interval Signal repeats N in the time domain₃Multiplied by corresponding Transmission Time Interval grade frequency expansion sequence after secondary, reach Transmission Time Interval grade spread spectrum Effect.

It should be noted that symbol level spread spectrum and Transmission Time Interval grade spread spectrum belong to time domain spread spectrum.

Under the conditions of existing LTE, reach according to the method that the prior art provides to adapt to the demand of the scenes such as M2M The covering gain of 20dB theoretically needs the repetition at most carrying out about 100 times to information to be sent to send, it is contemplated that practical letter Road estimation also needs 2 to 3 times of repetition, i.e., at most needs 300 repetitions to send.And the side provided through the embodiment of the present invention Case, it is assumed that the frequency domain spread spectrum factor is 8, and symbol level spreading factor is 12, Transmission Time Interval grade spreading factor is 3, then total expansion Frequency gain is 8 × 12 × 3=288, is equivalent to and carries out 288 repetitions to information to be sent, can substantially meet gain requirements most Big value；If the channel circumstance where some user equipmenies does not need so more spreading gains, base station can be according to corresponding Channel circumstance selects the spreading factor of different symbol level spreading factor and Transmission Time Interval grade spread spectrum, such as certain channel Under environment, it can reach according to the repetition transmission that the method that the prior art provides only needs to carry out information to be sent 100 times The covering gain of 20dB, then it is 8 that base station, which can keep the frequency domain spread spectrum factor, and selecting symbol level spreading factor is 13, transmission time Bay level spreading factor is 1 (Transmission Time Interval grade is not used to spread), and spreading gain total at this time is 8 × 13 × 1= 104。

In addition, may result in channel circumstance since biggish spreading factor will lead to longer spread spectrum time and change Become, to influence the orthogonality between spreading code, therefore, Transmission Time Interval grade frequency expansion sequence is unsuitable too long.Work as actual needs Transmission Time Interval grade frequency expansion sequence length it is longer when, transmission time first can be carried out according to a shorter frequency expansion sequence Bay level spread spectrum, then the information obtained after spread spectrum is replicated, it will be able to ensuring not influence the orthogonality between spreading code In the case where, reach spread spectrum effect actually required

Specifically, Transmission Time Interval grade spreading factor may include practical spreading factor and replicator.User equipment Transmission Time Interval grade frequency expansion sequence is generated according to practical spreading factor, and according to the Transmission Time Interval grade frequency expansion sequence of generation Transmission Time Interval grade spread spectrum is carried out to the first information to be sent, obtains the first Transmission Time Interval grade spread spectrum information, further according to Replicator replicates the first Transmission Time Interval grade spread spectrum information of acquisition.For example, if replicator is N₄, then use First Transmission Time Interval grade spread spectrum information is copied as N by family equipment₄Times.In practical applications, user equipment can also be by One Transmission Time Interval grade spread spectrum information copies as 2N₄、3N₄Or 4N₄Times etc., in this regard, the embodiment of the present invention does not do specific limit It is fixed.

Specifically for example, if the length of Transmission Time Interval grade frequency expansion sequence actually required is 100, if being using length 100 Transmission Time Interval grade frequency expansion sequence, then may result in channel circumstance and change, to influence between spreading code Orthogonality, at this point it is possible to set 4 × 25 for Transmission Time Interval grade spreading factor, wherein 4 be practical spreading factor, 25 For replicator.User equipment generates length according to practical spreading factor as 4 Transmission Time Interval grade frequency expansion sequence, and according to The Transmission Time Interval grade frequency expansion sequence that the length generated is 4 carries out the expansion of Transmission Time Interval grade to the first information to be sent Frequently, then by the first Transmission Time Interval grade spread spectrum information obtained after Transmission Time Interval grade spread spectrum replicate 25 times.

Step 203, the information after first spread spectrum of acquisition is sent to the base station by user equipment；

User equipment will be after the spread spectrum that obtained after frequency domain spread spectrum, symbol level spread spectrum and Transmission Time Interval grade spread spectrum Information be sent to base station.

Step 204, user equipment receives the information after the second spread spectrum of base station transmission；

Wherein, the information after second spread spectrum is the base station according to the frequency domain spread spectrum factor, symbol level spreading factor and biography Defeated time interval grade spreading factor carries out frequency domain spread spectrum, symbol level spread spectrum and Transmission Time Interval to the second information to be sent respectively The information obtained after grade spread spectrum.

Step 205, user equipment is according between the frequency domain spread spectrum factor, symbol level spreading factor and the transmission time got Frequency domain is despread, symbol level is despread and is transmitted is carried out respectively to the information after second spread spectrum received every grade spreading factor Time interval grade is despread.

User equipment can generate the frequency expansion sequence of frequency domain spread spectrum according to the frequency domain spread spectrum factor got, and according to generation Frequency domain spread spectrum frequency expansion sequence to this second spread spectrum after information carry out frequency domain despread；According to the symbol level spread spectrum got After the factor generates the frequency expansion sequence of symbol level spread spectrum, and the frequency expansion sequence spread according to the symbol level of generation is to second spread spectrum Information carries out symbol level and despreads；Transmission Time Interval grade spread spectrum is generated according to the Transmission Time Interval grade spreading factor got Frequency expansion sequence, and according to the Transmission Time Interval grade of generation spread spectrum frequency expansion sequence to this second spread spectrum after information pass Defeated time interval grade is despread.

Specifically, when including multiple user equipmenies in a system, frequency expansion sequence phase that each user equipment is got Mutually between be orthogonality relation, therefore, user equipment can according to get the frequency domain spread spectrum factor, symbol level spreading factor and Transmission Time Interval grade spreading factor generates corresponding frequency domain spread spectrum sequence, symbol level frequency expansion sequence and Transmission Time Interval grade Frequency expansion sequence, and by the signal received from base station multiplied by the frequency domain spread spectrum sequence of generation, symbol level frequency expansion sequence and transmission Time interval grade frequency expansion sequence, it can filtering base station is sent to the information of other user equipmenies, obtain base station be sent to The information of family equipment.

After spreading to information, the interference between each user can be eliminated by frequency expansion sequence, therefore, by upper Wireless communications method is stated, different user equipmenies can be carried out wireless communication by the full bandwidth of system channel with base station simultaneously, To guarantee higher power system capacity and resource utilization while improving covering gain.

In conclusion wireless communications method provided in an embodiment of the present invention, by obtaining the frequency domain spread spectrum factor, symbol level expands The frequency factor and Transmission Time Interval grade spreading factor, and information is sent or received according to the spreading factor got, it is sending When information, the effect sent after being spread to sent information carries out when simple repetition is sent with by information to be sent Effect is identical, and duplicate number is the product of three spreading factors, when receiving information, due to root between different user devices There is orthogonality according to the frequency expansion sequence that spreading factor generates, despreading according to spreading factor to the information received can Eliminate the interference of other users equipment.Therefore, wireless communications method provided in an embodiment of the present invention, solves and exists in the prior art Transmitting efficiency is low when carrying out simply repeating to send on frequency domain or time domain, is delayed longer, and with user equipment each in band bandwidth Between the more serious problem of interference, so that different user equipmenies is can use identical physical channel and carried out simultaneously with base station Wireless communication has reached while improving covering gain, has improved the purpose of power system capacity and resource utilization；In addition, this hair The wireless communications method that bright embodiment provides, also by carrying out Transmission Time Interval to information to be sent according to practical spreading factor Grade spread spectrum, and the information obtained after Transmission Time Interval grade spread spectrum is replicated according to replicator, it solves when biography When defeated time interval grade spreading factor value is excessive, it may result in channel circumstance and change, to influence between spreading code Orthogonality the problem of, reached while obtaining spread spectrum effect actually required, guaranteed the orthogonality between spreading code Purpose.

Fig. 3 is referred to, it illustrates the method flow diagrams of wireless communications method provided by one embodiment of the present invention.This reality Come in the base station applying example and being mainly applied in M2M system with the wireless communications method for example, the wireless communications method can be with Include:

Step 301, the frequency domain spread spectrum factor, symbol level spreading factor and Transmission Time Interval grade spreading factor are obtained；

Step 302, the frequency domain spread spectrum factor that will acquire, symbol level spreading factor and Transmission Time Interval grade spread spectrum because All or part of spreading factor in son is sent to user equipment；

Step 303, the information after receiving the first spread spectrum of user equipment transmission, and according to the frequency domain spread spectrum got The factor, symbol level spreading factor and Transmission Time Interval grade spreading factor to receive this first spread spectrum after information respectively into Line frequency domain is despread, symbol level despreads and despreads with Transmission Time Interval grade, and the information after first spread spectrum is that the user sets It is standby that the first information to be sent is divided according to the frequency domain spread spectrum factor, symbol level spreading factor and Transmission Time Interval grade spreading factor It carry out not the information that obtain after frequency domain spread spectrum, symbol level spread spectrum and Transmission Time Interval grade spread spectrum；Alternatively, should according to what is got The frequency domain spread spectrum factor, symbol level spreading factor and Transmission Time Interval grade spreading factor carry out frequency to the second information to be sent respectively Domain spread spectrum, symbol level spread spectrum and Transmission Time Interval grade spread spectrum, the information after obtaining the second spread spectrum, by the letter after second spread spectrum Breath is sent to the user equipment.

In conclusion wireless communications method provided in an embodiment of the present invention, by obtaining the frequency domain spread spectrum factor, symbol level expands The frequency factor and Transmission Time Interval grade spreading factor, and information is received or sent according to the spreading factor got, believe sending When breath, the effect sent after being spread to sent information carries out the simple effect repeated when sending with by information to be sent Fruit is identical, and duplicate number is the product of three spreading factors, when receiving information, due to basis between different user devices The frequency expansion sequence that spreading factor generates has orthogonality, and the information received is despread and can be disappeared according to spreading factor Except the interference of other users equipment.Therefore, wireless communications method provided in an embodiment of the present invention solves in the prior art in frequency It is low to carry out simple transmitting efficiency when repeating to send on domain or time domain, is delayed longer, and with user equipment each in band bandwidth it Between the more serious problem of interference, so that different user equipmenies is can use identical physical channel and carry out nothing with base station simultaneously Line communication has reached while improving covering gain, has improved the purpose of power system capacity and resource utilization.
