Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
Please with reference to Fig. 1, the embodiment of the invention provides a kind of radio communication method, and it comprises:
Step 102: obtain bit sequence to be sent, said bit sequence to be sent is in the wireless signaling bit sequence that is used to indicate transmission information in leading;
The specification of the bit sequence described in the embodiment of the invention and content all can with reference in 802.11 standards for the regulation of VHT-SIG bit sequence, repeat no more at this.
Step 104: through the adjustment bit sequence said bit sequence to be sent is carried out that XOR is handled or XNOR is handled, to reduce the transmitted power peak-to-average force ratio of said bit sequence to be sent;
In the embodiment of the invention, said adjustment bit sequence is the binary sequence that " 0 " and " 1 " is formed, and said XOR is handled and comprised: according to the position of the bit " 1 " in the adjustment bit sequence, with the corresponding bits position negate of bit sequence to be sent.Said XNOR is handled and is comprised: according to the position of the bit " 0 " in the adjustment bit sequence, with the corresponding bits position negate of bit sequence to be sent.Said negate is meant " 0 " in the corresponding bits position in the bit sequence to be sent is become " 1 " that perhaps " 1 " becomes " 0 ".Because the object of the invention is exactly through the adjustment bit sequence arrangement mode of original bit sequence to be made amendment, with the bit sequence arrangement mode of the expectation that obtains.Therefore, in practical operation, can in " xor operation " and " XNOR operation " this two, choose any one kind of them and carry out.
Regulation according to 802.11ac standard card cage document (framework); In VHT-SIG bit sequence to be sent; Some bit arrangement modes fixing " fixed bit " are arranged, and it is constant in some cases that the bit value of these " fixed bit " must be arranged, such as reservation bit position (Reserved Bit; All be " 1 " or all for " 0 "), and know the Group ID various flag such as (continuous " 1 " is " 0 " perhaps) in the bit under clean culture and the broadcast/multi broadcast situation.Therefore; Can set adjustment in the bit sequence with the bit value corresponding bit of these fixed bit; Make in the adjustment bit sequence with the adjustment bit with know bit " 0 " and the staggered appearance of bit " 1 " on the corresponding bit of bit; With with in the bit sequence to be sent owing to reservation bit or know that continuous " 0 " and " 1 " that bit produces is modified as irregular bit sequence, the probability of higher peak-to-average power ratio reduce to occur.
Concrete; For example, establish the adjustment bit sequence and be: S1=1 01011, carries out XOR when handling through the adjustment bit sequence to sent bit sequence; First bit in the bit sequence to be sent is " 0 "; Therefore and corresponding first bit of adjustment bit sequence be " 1 ", thereby after the XOR processing, " 0 " of first bit in the bit sequence to be sent just is changed to " 1 "; Second bit of adjustment bit sequence is " 0 ", still is " 0 " on second bit to be sent through the XOR processing.That is to say that when being " 0 " on the bit of adjustment bit sequence, the bit words on the corresponding bits position on the bit sequence to be sent does not change in XOR is handled; And on the bit of adjustment bit sequence, be " 1 ", the bit words on the corresponding bits position on the bit sequence then to be sent is in XOR is handled " negate ".Here; If suppose in the bit sequence to be sent and S1=1 01011; Corresponding bit is " 000000 "; Then handle, that is to say and to carry out negate to the 1st, 3,5 and 6 bits wherein, just obtained new bit sequence " 101011 " at last through the XOR of adjustment bit sequence.The principle that mode that XNOR is handled and XOR are handled is similar, repeats no more at this.
According to mentioned above; Be appreciated that; In alternate embodiments, saidly said bit sequence to be sent is carried out that XOR is handled or XNOR is handled and can be comprised through the adjustment bit sequence: through the adjustment bit sequence to the reservation bit in the said bit sequence to be sent or know that bit does XOR and handle; Perhaps, through the adjustment bit sequence to " 1 " bit continuously of comprising in the said bit sequence to be sent or continuously " a 0 " bit carry out XOR and handle.
Step 106: will pass through the bit sequence to be sent that XOR is handled or XNOR is handled and encode, and the result that will encode sends.
Through the radio communication method described in the embodiment of the invention; Bit arrangement mode in the bit sequence to be sent can change according to the bit arrangement mode of adjustment bit sequence; Even thereby comprise continuous " 0 " perhaps " 1 " in the original bit sequence to be sent; Under the effect that XOR is handled or XNOR is handled of adjustment bit sequence, also can become irregular bit sequence, thereby reduce the peak-to-average power ratio when sending bit sequence to be sent.

Certainly; Only disclosed and reservation bit, nine corresponding bits of Group ID that knows bit and N_STS end in the bit sequence after the adjustment bit sequence S that preceding text provided, pending bit sequence and the processing; And in fact; Regulation according to 802.11; The VHT-SIG bit sequence also has other bits of 6 bits except that nine at reservation bit, the Group ID that knows bit and N_STS end, can be according to actual needs reset perhaps " 1 " on corresponding bit, the XOR of these bits is handled or XNOR is handled realizing.
In addition; When receiving terminal receives and pass through the bit preface time-like that XOR is handled or XNOR is handled; Only need to adopt identical adjustment bit sequence the bit sequence that receives is carried out XOR is handled or XNOR is handled again, can obtain the bit sequence identical with bit sequence to be sent.Therefore, the radio communication method that the embodiment of the invention provided can be compatible with existing standard.
